Sprocket 16B-3 z=114 for Taper-Lock bush 4545, cast iron

Product Description

Sprocket 16B-3 z=114 for Taper-Lock bush 4545, cast iron works with 16B-3 roller chain (European standard DIN 8187 / ISO 606), triple-strand (triplex), with a pitch of 25.4 mm (1"). It has 114 teeth and is made of EN-GJL-250 cast iron.

The sprocket has a seat for a Taper-Lock 4545 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 4545 bush with a bore that matches the shaft. The hub diameter is 260 mm and the total width of the sprocket is 114 mm. The bush is not included - the 4545 bush can be purchased separately from our range.

Technical data

Applications

It is designed for heavy-duty drives: aggregate conveyors, construction machinery and mining equipment. The triple-strand version is chosen for very heavily loaded drives where there is no room for a chain with a larger pitch. The cast iron design works well for large sprockets in reduction gears, where rigidity and vibration damping matter.

Frequently asked questions

Which chain does this sprocket fit?

16B-3 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 25.4 mm. A triplex sprocket requires a triple-strand (triplex) chain.

Does it fit ASA 80 chain?

No. ASA 80 chain (American standard) has the same pitch and roller diameter, but a different inner width (15.88 mm instead of 17.02 mm). The 16B 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 921.81 mm, and the outside diameter De is 934.3 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.

How should sprockets be aligned during installation?

The driving and driven sprockets must lie in one plane. Alignment can be checked with a long steel straightedge placed against the sides of both wheels or with a laser alignment tool. Even a small misalignment wears the sides of the teeth and speeds up chain wear.

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.
