Description of PLE Economic Planetary Gearbox

MKD PLE series planetary reducer is a kind of spur gearbox which is designed especially for stepper motor and servo motor. MKD PLE planetary gearboxes are standard type and cost-saving precision gearbox for customers who have a limited budget. This series gearbox has a cycloid main body and it is designed without flange to meet different requirements of customers. MKD spur planetary gearboxes to have speed ratios from 3-100 and with input stair diameters from φ30-150mm, which can greatly meet customer’s different application needs. For more detailed dimensions, please download the MKD product catalog from the website. These precision gearboxes are widely matched with servo motors or stepper motors of brands like Panasonic, Fanuc, SIEMENS, Matsushita, Mitsubishi, Lenz, Yaskawa, etc.

Transmission Construction of Planetary Gearbox

For a single-stage planetary reducer, the main transmission structure consists of an internal gear, three planetary gears, and one sun gear.

Application of PLE Economic Planetary Gearboxes

MKD PLE inline gearboxes are an economic alternative to the high precision planetary gearboxes, which are widely used in the fields of machine tools, textile, printers, packaging machinery, rubber machinery, production lines, cutting machine, mechanical arm-gantry, aluminum doors and windows equipment, sealing machines, testing machine, etc.

The material of MKD Gears, planet carrier, and housing

The ring gear of MKD is made of treated steel, which is a main part of the housing. And the sun and planet gears are made of hardened steel. Both of bearing flanges are made of aluminum. The whole planet carrier and output shaft are made of ductile cast iron and have a sturdy design.
