pulley sheave centers that will mate with metric conical 1:5 tapered k

[marvelmaker]

Here's one for you!

Our customer has bought some gear motors from us for a pulley drive system, and found out a week before receiving the gear motors that the shaft requested will not mount to his pulley sheave easily. His pulley sheave manufacturer indicated not only did he not have the tooling, the machining details did not exist in the Machinery Handbook!

Conical tapered 1:5 metric shaft is a standard shaft for European gear product, but I suspect, since I am in Canada, not Europe, that there are not many pulley drive systems in Europe that use this shaft. There aren't any easily found manufacturers here in Canada or North America either. I hope I am not treading into deep water by asking if anyone has run into a solution for this, or knows of a company that has already pre-designed a pulley sheave to accept conical tapered keyed 1:5 shaft?

Can you not buy a pulley with a taperlock type bushing ( ie Dodge, Woods) and have a machine shop machine the ID of the bushing to suit the shaft? Maybe I misunderstood ?

Thanks, ruble, is perhaps I didn't make the question clear.

Our main gear motor factory is in Europe.

In this case our customer asked for this shaft on a gear motor for his pulley drive system.

Our customer cannot find a pulley sheave that is pre-designed (or already built) to handle a conical 1:5 tapered keyed shaft on, in our case, a gear motor. The shaft would mount directly to the inner diameter of the pulley sheave, and be bolted in place. We are considering trying to switch at this late into production with a conical 1:8 tapered keyed shaft. But it is not that easy.

The best solution is find a supplier or find the machining detail and buy the tooling. Since it is prototype, we might be able to switch shafts for production. Or am I missing something. Appreciate your reply or anyone else's.
