An Elastic Deformation Cycloid Drive

Elacloid Drive of MINTROBOT Co. Ltd. is a precise speed reducer unit that overcame the miniaturization limit of a traditional cycloid drive and realized lightweight. It can implement high-precision with cost-effective, and is suitable for the robot manipulators that can be used in casual and semi-industrial application.

High Presicion

 

The essential components of the Elacloid Drive are manufactured through precision machining in 0.001mm increments, and can ensure low backlash and angle transmission error. Compared to a planetary gear reducer of similar price, it shows remarkably low backlash and transmission error, and performs a precision of 90% compared to an expensive harmonic drive reducer.

Light-Weight

 

The Elacloid Drive uses an aluminum body to reduce unnecessary weight except the components required high hardness. This can help reduce the weight of the robot and also reduce the required power to support the weight of itself.
