Sprocket 06B-3 z=38 for Taper-Lock bush 1615

Product Description

Sprocket 06B-3 z=38 for Taper-Lock bush 1615 works with 06B-3 roller chain (European standard DIN 8187 / ISO 606), triple-strand (triplex), with a pitch of 9.525 mm (3/8"). It has 38 teeth and is made of C45 steel.

The sprocket has a seat for a Taper-Lock 1615 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 1615 bush with a bore that matches the shaft. The hub diameter is 90 mm and the total width of the sprocket is 38 mm. The bush is not included - the 1615 bush can be purchased separately from our range.

Technical data

Applications

It is found in agricultural machinery, workshop equipment and gate drives. 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?

06B-3 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 9.525 mm. A triplex sprocket requires a triple-strand (triplex) chain.

Does it fit ASA 35 chain?

No. ASA 35 chain (American standard) has the same pitch, but a different roller diameter (5.08 mm instead of 6.35 mm) and a different inner width (4.77 mm instead of 5.72 mm). The 06B 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 9.525 mm (3/8").

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 115.35 mm, and the outside diameter De is 119.5 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.
