Sprocket 24B-1 z=17 with hub

Product Description

Sprocket 24B-1 z=17, with hub

Sprocket 24B-1 (pitch 1 1/2" - 38.1 mm), simplex, 17 teeth, with hub. 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

How important is the concentricity of the hub bore relative to the toothed rim?

If the hub bore is not machined concentrically with the toothed rim, the sprocket will "run out" during operation - the teeth will engage the chain at a varying angle, which accelerates their wear and generates additional vibration. That is why boring out the pilot bore must be done on a lathe, clamping the sprocket by the hub or rim, and not "by eye".

How does the choice of the number of teeth affect vibration levels and drive operation?

A smaller number of teeth means fewer meshing points per revolution and larger fluctuations in the instantaneous chain speed (the so-called polygon effect), which results in higher vibration levels. Increasing the number of teeth of the sprocket (at the same pitch) smooths the operation of the drive, although it increases its overall dimensions.

How do you select the number of teeth on the driving and driven sprockets to obtain the required ratio?

The ratio is calculated as the quotient of the number of teeth on the driven sprocket and the number of teeth on the driving sprocket. For example, to halve the rotational speed, the driven sprocket should have twice as many teeth as the driving sprocket - both sprockets must have the same pitch and number of strands.

Is it worth using guards on sprockets and the entire drive?

Yes - a guard protects operators from contact with moving parts and at the same time limits the ingress of dust and moisture to the chain, which genuinely extends its service life. In many industrial machines, a chain drive guard is also an occupational safety requirement.

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.
