Non-Contact Magnetic Gears

Non-Contact Magnetic Gears

Clean, Quiet and Safe Motion Powered by Non-Contact Technology

For applications where particle generation from surface wear may be a concern, such as cleanroom operations, or for design engineers looking to reduce lubrication requirements, noise or vibration, a non-contact solution could be the right choice.

The new non-contact range from KHK Motion Drives includes:

• Magnetic gears
• Magnetic couplings
• Magnetic rack & pinion
• Magnetic speed reducers

What Are Magnetic Gears?

A magnetic gear, also known as a non-contact gear, is a toothless power-transmission component that utilises magnetic force from permanent magnets (such as neodymium magnets) to transfer rotational speed and torque between two shafts without physical contact.

What Are the Benefits of Magnetic Gears or Non-Contact Technology?

• No particle generation from tooth surface wear
• Operates without the need for lubrication
• Barrier transmission allows for seal-less designs
• Low noise and vibration due to non-contact power transmission
• Easy assembly with high angular and eccentric misalignment tolerance
• Magnetic slip under overload conditions enhances safety conditions
