greatest accuracy with Wuma gear reduction motor

Wuma gear reduction motor ,Having worked out the pitch/tpi required for the worm gear and referred to the lists, in most cases it will be found that there are many combinations that come sufficiently close. The main benefit of this is that it should enable a suitable combination to be selected even if the lathe is missing some of its changewheels.
bevel gear sets for greatest accuracy, in most cases, it will be a three driver, three driven assembly that achieves this. However, frequently, there will be two driver, two driven assemblies that come very close, the viewer will of course have to decide if the application demands the more accurate result, in many cases this will not be a requirement.
