What is a planetary gear motor

2021-04-15 16:33:28   |  What is a planetary gear motor

  What is a planetary gear motor? In engineering projects, considering the design specifications, required performance or space constraints, different types of gear motors are required to complete the corresponding transmission. Gear motors include different gear types. Common types include spur gears, worm gears, helical gears, planetary gears, and even harmonic gears. The common type used with DC motors is planetary gear motors.

What is a planetary gear motor

  1. Application of planetary gear motor

  These gears are sometimes referred to as "epicycloid" gears. The points on the rotating planet track the epicycloid curve as it rotates. The term "planet" is also applicable. The rotation of the entire assembly around the central sun gear mimics the motion of the solar system. Gear trains are increasingly used as actuators to obtain more torque from smaller drive train components. Planetary gear trains are also used in differential systems and applications requiring very low reduction ratios. The input, output and auxiliary shafts can be connected to any of the three stages to achieve the speed/torque requirements of the application.

  2. The structure of a typical planetary gear motor

  The planetary gear head is composed of a sun gear, a ring gear and a planet carrier assembly using three to five planet gears. The sun gear is usually a motor pinion, and the ring gear is usually in the housing. The planet carrier is usually a cast or powder metallurgy It is made with many screws on it, and planets rotate on it. The planetary gears share the load and rotate around the sun gear. The output shaft is usually connected to the output stage on the planetary gear carrier. Lubrication is usually a viscous grease.
