Sprocket 08B-3 z=23 with hub

Product Description

Sprocket 08B-3 z=23, with hub

Sprocket 08B-3, triplex (three-strand), with 23 teeth and a hub - pitch 1/2" (12.7 mm). The material is C45E carbon steel (EN 10083-1), and the teeth remain unhardened (without induction hardening) - in accordance with DIN 8187 / ISO 606; this version is easier to machine over the entire depth of the sprocket.

Technical data

Frequently asked questions

What is the relationship between the number of teeth of a sprocket and the rotational speed of the drive?

This is the basic principle of the transmission ratio. If there is a small sprocket on the motor (drive) and a large one on the machine, the machine will turn more slowly but gain proportionally greater torque (force).

How often should chain tension be checked on a machine in operation?

In machines operating continuously, it is advisable to check the tension every few weeks, and in a newly installed drive - as early as after the first hours of operation, when the chain "beds in". A correctly tensioned chain has a slight, visible sag on the slack side - too tight a chain accelerates bearing wear, while too loose a chain increases the risk of it jumping off the sprocket.

When is it worth using a clamping bush (Taper Bush) for a sprocket?

Wherever fast assembly matters. A clamping bush eliminates the need for laborious boring of the hub and cutting of a keyway - you insert the sprocket, tighten the screws and the machine is back in operation within minutes.

How does a sprocket differ from a module spur gear?

A sprocket works with a roller chain and has a tooth profile matched to the chain rollers (standard DIN 8187/ISO 606), whereas a module spur gear meshes directly with another gear or a gear rack, has an involute tooth profile and parameters described by the module (standard DIN 780/ISO 54). These are two different power transmission systems, not interchangeable with each other.

Where is this product used?

This type of sprocket is used in drives of agricultural and industrial machinery, including screw and bucket conveyors, feed conveyors, packaging machines and internal transport systems.
