Sprocket 16B-1 z=114 with hub, Cast iron

Product Description

Sprocket 16B-1 z=114, with cast iron hub

Sprocket 16B-1, simplex, with 114 teeth and a hub - pitch 1" (25.4 mm). The material is grey cast iron - an economical solution with good vibration damping that proves itself in drives running at constant speed; the hub has a pilot bore that must be bored out individually to suit the shaft.

Technical data

Frequently asked questions

Can the hub of a sprocket have a different hardness from the toothed rim?

Yes, and in practice this is usually the case - in the version with induction-hardened teeth, only the toothed rim is hardened, while the hub remains soft so that it can be freely turned and a keyway can be cut in it. This solution combines tooth wear resistance with ease of machining the hub.

How does uneven tooth wear affect machine vibration?

Worn teeth cause the so-called polygon effect - the chain drops off and climbs onto the teeth abruptly, which transmits vibrations to the shafts, destroys the bearings and leads to cracking of welds in the machine.

When ordering several sprockets for one drive, do they have identical production parameters?

Sprockets of the same catalogue item are produced according to the same documentation and tolerances, so their parameters (pitch, number of teeth, dimensions) match each other regardless of when they were ordered. Any slight differences in the shade of the steel between production batches have no effect on how the sprocket works with the chain.

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.

Does a cast iron sprocket require a different chain than a steel sprocket of the same pitch?

No - the tooth geometry and pitch are identical to those of the steel version of the same size, so the cast iron sprocket works with the same chain. The difference lies in the material of the hub and rim: cast iron dampens vibrations better and is cheaper, but withstands impacts and operation at high rotational speeds less well than steel.

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.
