Hi all, looking for a supplier of Helical gears….prefer from stock….

I need a matched pair between 75-100mm about 20-25mm tooth thickness and

hardened …

these are to run in mesh one above the other to reverse the direction of the driven gear…..to transmit 2-5hp at varying speeds…..constant load…..

this is to drive a camshaft (4 cylinder petrol) in the past they were driven by ally or even fiber gears meshed with a steel one…

any ideas…many thanks Clogs

One possible solution is two sets of replacment angle grinder gears that are sold on eBay. I do not know if any of them would be as large as 75mm (I assume this is the diameter.)

I found Paul Wheeler at Cross & Morse of Birmingham very helpful. 021 360 0155. They have a online catalogue so you might find what you seek there. I ordered a pair of bevel gears and they were delivered the following day.

HPC Gears at Chesterfield.

**LINK** Also do a priced on-line catalogue.

Only problem with stock ears is they are usually pilot bore as they don't know what you want them for and therefore unhardened although you do have a choice of materials.
