What are magnetic bevel gears?

Magnetic bevel gear is another type of non-contact right-angle magnetic transmission system. Unlike the CT (cross type) series, it differs in terms of torque and transmission ratio. A magnetic bevel gear/coupling consists of a disc coupling and a PT (cross type) series magnetic pinion gear. The standard material for the surface is stainless steel 304, but PVC (Polyvinyl chloride) and stainless steel 316L can also be customized. The standard internal magnet material is neodymium iron boron, but samarium cobalt magnet can also be customized, allowing the high-temperature resistance to be increased from 80C (176F) to 280C (536F).

They are non-contact power transmission mechanisms making use of the attraction and repulsion properties of the magnets.

This component facilitates contactless 90° drive transmission across intersecting axes. The clearance can be adjusted freely via the set screw on the holder, allowing for fine-tuning of the torque.

Magnetic bevel gears application:

Transportation equipment, conveyor

You may eliminate micro-step vibration or driving noise caused by mechanical gears.Recommended for presision devices handling due to less influence of vibration, no wear-out of gear.
