Sprocket 10B-3 z=30 for Taper-Lock bush 2517

Product Description

Sprocket 10B-3 z=30 for Taper-Lock bush 2517 fits 10B-3 roller chain (European standard DIN 8187 / ISO 606), triple-strand (triplex), with a pitch of 15.875 mm (5/8"). It has 30 teeth and is made of C45 steel.

The sprocket has a seat for a Taper-Lock 2517 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 2517 bush with a bore that matches the shaft. The hub diameter is 120 mm and the total width of the sprocket is 45 mm. The bush is not included - the 2517 bush can be purchased separately from our range.

Technical data

Applications

It is used in woodworking machinery, winches and internal transport equipment. The triple-strand version is chosen for very heavily loaded drives where there is no room for a chain with a larger pitch.

Frequently asked questions

Which chain does this sprocket fit?

10B-3 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 15.875 mm. A triplex sprocket requires a triple-strand (triplex) chain.

Does it fit ASA 50 chain?

No. ASA 50 chain (American standard) has the same pitch and roller diameter, but a different inner width (9.52 mm instead of 9.65 mm). The 10B sprocket is designed for European-standard chain, so the two systems should not be mixed.

How do I check the pitch of a sprocket?

The sprocket pitch matches the chain pitch - it is the distance between the centres of adjacent teeth measured on the pitch circle. The easiest way to check it is to place a section of matching chain on the sprocket: it should sit on the teeth without tension. This sprocket has a pitch of 15.875 mm (5/8").

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 151.87 mm, and the outside diameter De is 158.8 mm.

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.
