Timing belt pulley 14M 170 z=28 steel

Product Description

Timing belt pulley 14M 170 z=28 steel - for HTD 14M belts with a pitch of 14 mm (HTD). Made of C45 steel.

The pilot bore allows the pulley to be bored precisely to the shaft size and the fit required by the machine, to H7 tolerance. The keyway is cut on a slotting machine according to DIN 6885.

Typical applications: heavy industrial drives, presses, agricultural and construction machinery.

FAQ

What is a pilot bore and how is it rebored?

A pilot bore is a technological bore smaller than the target shaft diameter - a turner rebores it precisely to the specific shaft, to H7 tolerance. The keyway is cut on a slotting machine according to DIN 6885.

How do you align pulleys correctly?

The grooves of both pulleys must lie in one plane. Check this with a straightedge or a laser alignment tool. Even a slight lateral misalignment causes rapid wear of the belt's side edges.

How do you choose a pulley for a toothed belt?

The key is matching the series (14M = 14 mm pitch (HTD)) and the belt width (170 mm). The drive ratio is calculated by dividing the number of teeth of the driven pulley by the number of teeth of the driving pulley.

How can you recognise a worn pulley groove?

If the bottom of the groove is shiny, the belt has bottomed out and no longer wedges against the flanks - the pulley needs replacing. Profile gauges are used for checking.
