Right Angle Gearboxes - Answers to Common Questions

Показать описание

In this video, W.C. Branham’s Chad Randleman answers some of the most common questions we receive regarding right-angle gearboxes.

Are your gearboxes bi-directional?

The answer is yes. Both our crossed helical and spiral bevel gearboxes, as well as the worm drive gearboxes, are bi-directional and the input shaft can be rotated in either direction.

What are your required shaft and keyway fits and tolerances for your Insert-A-Shaft gearboxes?

If a free-sliding fit is desired, your shafting should have a nominal dimension with a tolerance of plus zero, minus two-thousand seven-inch. The same goes for the keyway. If a free-sliding fit is desired, your keyway width should also have a nominal dimension of plus zero, minus two-thousand tolerance. This will ensure that your shafting slides freely into the bores of the Insert-A-Shaft gearbox and no binding occurs.

Can your gearboxes be mounted in any orientation?

The answer is yes. The gearboxes are sealed in all axes and can be mounted in any orientation — vertical, horizontal, upside down — you name it.

What ratios are your gearboxes available in?

Both the crossed helical and the spiral bevel style gearboxes are common in low ratios. For the helical, we offer 1:1, 2:1 and 3:2 ratios. For the spiral bevel gearboxes, 1:1 ratios are the most common and 2:1 ratios are also available. For worm style gearboxes, higher ratios are the norm and we offer them both in 10:1 and 20:1 ratios.
