Renold Chain India Pvt Ltd Vedasandur, Dindigul, Tamil Nadu

The Renold range of engineering class chain includes a complete line of welded steel mill and drag chains.  The quality and performance of our welded steel chains have been the industry standard for decades. For the full range of welded steel chains available, please contact us.   Type W   Permaweld chains are normally of cranked link construction. The pins have a press fit into the side plates, thus eliminating unnecessary wear due to pin movement. Accurate punching of the plate, automated machine welding and assembly of the bushes to side plates ensures high quality and dimensional control. Steels of medium carbon grades are used for pin and plates and may be heat treated to produce greater strength and wear resistance. Bushes are of carburising grades of carbon steel which may be case hardened.   Type WD   Type WD Permaweld drag chains are furnished with heat treated pins and formed steel bushes. The bushes are shaped to provide maximum conveying capacity, shock resistance, toughness and higher yield strength in bending than many comparable cast and other welded links. Precise press fits of the pins in the side plates and single flats milled on the pin ends prevent unnecessary wear due to pin movement. Pins and side plates are made of medium carbon steels. Bushes are of carburising grade steels which are case hardened on the heat treated chains. Accurately punched holes and assembly procedures ensure dimensional control. The flexibility of welded construction provides a wider range of attachment links than is normally offered for similar cast chains.

Renold has extensive experience in supplying theme parks around the world with conveyor chain for theme park rides, from roller coasters to water rides. Through continuous research and development and examining the common causes of chain failure in corrosive environments, Renold has developed the Trident Chain series to tackle the three main areas of failure in such environments: corrosion, seizure and wear.   Tackling Corrosion Due to constant exposure to water, corrosion is often an issue on water ride chains. To address this, Renold has developed a dual process surface treatment to increase corrosion resistance. The zinc based specialised coating offers superior protection of the steel. Even when the coating is penetrated, the treatment continues to offer superior corrosion resistance.   Eliminating Seizure   Transfer and lift chain on rides can suffer from seizure of the bush and pin and significantly shorten the life of the chain. Through the development of a unique polymer sleeve, metal-to-metal contact is reduced, thereby eliminating the risk of the bush and pin seizure. This also provides lubrication-free operation and removes the need for any lubrication ports.   Reducing Wear   Development of a heavy wall bush design overcomes premature wear and failure of the bush, and in most cases a shell roller can also be incorporated which reduces wear on sprocket teeth; increasing life of both the sprocket and chain – and reducing maintenance time and cost.Additional Benefits Integral attachment design – eliminates attachment/plate corrosion issues Smoother and quieter operation than standard water ride chain Operates on the same sprockets and track as standard chain. Superior breaking load and working load *in salt spray testsNOTE: Polymer sleeve highlighted in yellow for illustration purposes onlyFor more information on Renold Trident and how it can reduce costs for your theme park rides, call us today on +44 (0) 161 498 4600 or use fill in our request form for more information.

Renold Ajax carries a full line of standard gear couplings that conforms to the AGMA gear coupling specification number.  They are offered in o-ring or metal seal designs, and include quality features such as fitted bolts, crowned and barreled teeth with tooth tip piloting, and forged steel components. The Renold Ajax metal seal design coupling uses a unique method of seal retention that will not allow the seal to separate from the ring gear during operation. This seal design also allows a metal seal ring gear to easily be converted to an o-ring seal configuration and back to metal seal if needed.  Renold Ajax standard couplings also include a line of D- and DS-Series high misalignment couplings that are capable of operation at up to 6 degrees misalignment. The D-Series couplings use a piloted flange for connection while the DS-Series couplings have a detachable sleeve for connection in applications with a diameter restriction such as levelers.

Conveyor chain, like transmission roller chain, can be manufactured to a number of different international standards. The main standards available are: British Standard (BS)This standard covers chain manufactured to suit the British market and markets where a strong British presence has dominated engineering design and purchasing. The standard is based on the original Renold Conveyor Chain design.ISO Standard ChainChain manufactured to ISO Standard is not interchangeable with BS or DIN Standard Chain. This standard has a wide acceptance in the European market, except in Germany. Chain manufactured to this standard is becoming more popular and are used extensively in the Scandinavian region. Renold has extensive experience in the manufacture of conveyor chain. The Renold specification of conveyor chain has taken many years in design and development to achieve the optimum product.  In order to ensure this is translated into product performance, we strictly control: Materials Heat Treatment Processes Fits Attachment Assembly Lubrication   Renold Ultimate Reliability The key to Renold chain reliability is consistency in design and manufacture. Maximum chain strength and resistance to wear are achieved by strict control of the material specification and by using state of the art heat treatment processes. The consistent overall tolerances of Renold chain make it ideal for conveying systems requiring precise alignment on multi-strand chain layouts. Breaking loads exceed the minimum international standards. Correct chain selection is essential for optimum performance. Renold’s experienced design team are always available to freely advise on particular products and applications. Standard and Deep Link conveyor chain is available to BS4116 Part 4 as well as ISO 1977, with both Hollow and Solid Bearing Pins.  Extra Strength Standard Conveyor Chain To complement our standard range of British Standard Conveyor Chain, this extra strength chain is more suitable for conveyor applications selected on ultimate tensile strength (breaking load). Each chain is the same dimensionally as its normal counterpart, for example an extra strength 24000 lbs chain has basically the same dimensions as a normal 12000 lbs series chain. This chain is used extensively in the conveying of animal feed and bulk food stuffs such as grain, maize, wheat and raw food mixtures. Most of these applications use scraper type conveyor systems that normally have long centre distances between sprockets. Such systems are sometimes slow moving with little or no shock loading. Contact our technical sales staff for selection and applicational details.

The Standard Chain Wear Guide from Renold is a quick and easy way to measure chain elongation. You can clearly see that if your chain has reached or even exceeded the recommended limit of 2% wear extension then it is time for the chain to be replaced. Make sure that chain wear doesn't cause you problems like downtime, lost production and reduced profitability. Watch our video on the right to see how to use the Renold Chain Wear Guide correctly.

Standard attachments are parts fitted to a base chain to adapt it for a particular purpose as a conveying medium. Attachments may form an integral part of the link plate or may be built into the chain as a replacement of the normal link. Other attachments (according to type) are fixed to the chain plates by projection or fillet welding, to either one or both sides of the chain. Standard attachments are described below:   F AttachmentsOuter or Inner Links F Attachments provide a flat surface at right angles to the chain plate. They are used for securing pushers, scraper bars, etc.   K Attachments Outer or Inner Links K Attachments provide a platform parallel to the chain line and bearing pin axis. They are used for securing slats, scrapers, buckets etc. to the chain.   L Attachments L Attachments are integral with the chain outer plates. Normally they have one or two holes (L2 preferred), but for use on scraper applications they can be supplied without holes and with various box widths (LO Type).   Outboard Rollers For use on Hollow Bearing Pin Chain Outboard rollers have two principal advantages; as direct load carriers they enable the chain rollers to be used solely for gearing purposes and in the event of outboard roller wear, they can be replaced easily without recourse to chain replacement. They are particularly useful when attachments prevent the gearing rollers running on support tracks on the return run or where the roller loading is high.   Spigot Pins & Holed Link Plates Spigot pins may be assembled either through hollow bearing pins or link plates and are secured by a nut and spring washer. Single holing is primarily for use with spigot pins and is required on both sides of the chain. Double holing is provided for the assembly of special attachments on one or both sides of the chain. The holes in the inner plates are countersunk on the inside face to prevent the bolt heads fouling the sprocket teeth.

Renold offer a comprehensive range of transmission chain sprockets for British Standard chain up to two inch pitch, ensuring maximum working life and productivity for your application. Other sizes of sprocket, including those to American Standard dimensions, are available on request. Special sprockets are also manufactured on request, in special materials or formats, normally to suit a specific applications in harsh or difficult drive situations, such as; Sprockets incorporating shafts Welded or detachable hubs Shear pin devices fitted Necklace sprockets made up of chain plates and individual tooth sections for turning large drums or tables. Combination sprockets (two or more sprockets combined having different pitch sizes and numbers of teeth). Sprockets in two or more sections, i.e. split sprockets or segmental sprockets.   Sprocket and Chain CompatibilityMost drives have an even number of pitches in the chain and by using a driver sprocket with an odd number of teeth, uniform wear distribution over both chain and sprocket teeth is ensured. Even numbers of teeth for both the driver and the driven sprockets can be used, but wear distribution on both the sprocket teeth and chain is poor.   Number of TeethThe maximum number of teeth in any driven sprocket should not exceed 114. This limitation is due to the fact that for a given elongation of chain due to wear, the working pitch diameter of the chain on the sprocket increases in relation to the nominal pitch diameter, i.e. the chain assumes a higher position on the sprocket tooth. The allowable safe chain wear is considered to be in the order of 2% elongation over nominal length. A simple formula for determining how much chain elongation a sprocket can accommodate is 200/N expressed as a percentage where N is the number of teeth on the largest sprocket in the drive system. It is good practice to have the sum of teeth not less than 50 where both the driver and the driven sprockets are operated by the same chain, e.g. on a 1:1 ratio drive. Both sprockets should have 25 teeth each. Centre Distance For optimum wear life, centre distance between two sprockets should normally be within the range 30 to 50 times the chain pitch. On drive proposals with centre distances below 30 pitches or greater than 2 metres, we would recommend that the drive details are discussed with our technical staff. The minimum centre distance is sometimes governed by the amount of chain lap on the driver sprocket, our normal recommendation in this circumstance being not less than six teeth in engagement with the chain.  The centre distance is also governed by the desirability of using a chain with an uneven number of pitches to avoid the use of a cranked link, a practice that is not recommended except in special circumstances. For a drive in the horizontal plane, the shortest centre distance possible should be used consonant with recommended chain lap (maximum six teeth) on the driver sprocket.
