Sprocket 32B-3 (2") z=57 plate wheel, C45 steel

Product Description

Sprocket 32B-3 (2") z=57 plate wheel, C45 steel is designed for 32B-3 roller chain (European standard DIN 8187 / ISO 606), triple-strand (triplex), with a pitch of 50.8 mm (2"). It has 57 teeth and is made of C45 steel.

The plate wheel has a pilot bore of Ø40 mm. It can be bolted or welded to your own hub, flange or drum, which makes it a good choice for larger ratios and non-standard designs.

Technical data

Applications

It works in drives of lifts, winches and heavy chain conveyors. The triple-strand version is chosen for very heavily loaded drives where there is no room for a chain with a larger pitch. Plate wheels are often mounted on drums and flanges and in large reduction gears.

Frequently asked questions

Which chain does the 32B-3 z=57 sprocket fit?

32B-3 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 50.8 mm. A triplex sprocket requires a triple-strand (triplex) chain.

Does it fit ASA 160 chain?

No. ASA 160 chain (American standard) has the same pitch, but a different roller diameter (28.58 mm instead of 29.21 mm) and a different inner width (31.75 mm instead of 30.99 mm). The 32B sprocket is designed for European-standard chain, so the two systems should not be mixed.

How is the pitch diameter of a sprocket calculated?

The pitch diameter Dp is the circle along which the chain rollers travel. It is calculated with the formula: pitch divided by the sine of (180° / number of teeth). For this sprocket it is 922.16 mm, and the outside diameter De is 945 mm.

When should I choose a plate wheel and when a sprocket with hub?

A plate wheel is chosen when the wheel is fixed to an existing flange, drum or your own hub, or when there is little space on the shaft. A sprocket with hub works better where torque is transmitted directly from the shaft via a key.

How does the number of teeth affect the drive ratio?

The ratio is the number of teeth of the driven wheel divided by the number of teeth of the driving wheel. If this sprocket drives a wheel with twice as many teeth, the driven shaft turns twice as slowly but with roughly twice the torque.

What does the lead time depend on?

When ordering, please check the current stock level of this sprocket - the lead time depends on it and is clearly stated according to the quantity available in each warehouse. The stock level is shown above the product price and may vary depending on the warehouse.
