TMR142 Series High Precision Planetary Gearbox Helical Gear Reducer Overview

TMR142 Series High Precision Planetary Gearbox Helical Gear Reducer, also known as servo motor planetary gearbox and low backlash planetary gearbox, is a type of gearbox that is commonly used in industrial automation equipment for precise speed control and position positioning. This gearbox is designed to provide high precision, low backlash, and high torque capacity. The product is widely used in various fields such as robotics, medical equipment, aerospace, and automotive manufacturing.

High Precision Planetary Gearbox Basic Structure

The High Precision Planetary Gearbox consists of several key components:

• Sun Gear: Located in the center of the planetary gearbox, the sun gear is typically connected to the input shaft or fixed to the housing as a stationary component.
• Planet Gears: The planet gears revolve around the sun gear and are supported and maintained in their relative positions by the planet carrier. Each planet gear meshes with both the sun gear and the ring gear, and they jointly bear and distribute the load when the power is input.
• Planet Carrier: The planet carrier is a structure with multiple planet gear shaft holes, which carries the planet gears and allows them to rotate relative to the sun gear. The planet carrier can serve as an output element or connect with another shaft to transmit or receive torque.
• Ring Gear/Annulus: The internal gear is a large-diameter annular gear fixed inside the gearbox housing, and its inner and outer surfaces have teeth that mesh with the planet gears. In some applications, the internal gear can also serve as an input or output end.
• Bearings and Shaft System: The bearings in the high-precision planetary gearbox are used to support the input shaft, output shaft, and planet carrier, ensuring stable rotation and smooth operation between the components.
• Housing: The housing is a sturdy structure that encloses all internal components, providing a stable support environment for the gears while protecting the interior from external impurities. It may also contain cooling or lubrication systems.
• Shafts and Keys: The input and output shafts are connected to the sun gear or planet carrier with a key to transmit power, ensuring precise torque transmission and axial positioning.
• Seals: Seals are used to prevent lubricating oil leakage and the entry of contaminants into the gearbox, ensuring internal cleanliness and good lubrication status.

High Precision Planetary Gearbox Working Principle

The working principle of the High Precision Planetary Gearbox is based on the following:

• Torque Transmission and Amplification: When the power is transmitted from the input shaft to the sun gear, the sun gear starts to rotate. Because the planet gears mesh with both the sun gear and the internal gear and revolve and rotate, the load is evenly distributed among them due to the combined action of multiple sets of planet gears, which can significantly increase the torque at the output end and achieve torque amplification.
• Speed and Gear Ratio Control: By adjusting the tooth number ratio between the sun gear, planet gears, and internal gear, the speed relationship and gear ratio between the input and output can be precisely controlled. For example, if the number of planet gears is large or the difference between the tooth numbers of the sun gear and internal gear is large, the gear ratio will increase, the output speed will decrease, and the torque will correspondingly increase.
• Low Backlash Feature: The High Precision Planetary Gearbox pays particular attention to reducing or eliminating the clearance between the gears, namely, "zero/low backlash." This is usually achieved through precision processing, preloading technology, and component selection to ensure extremely high motion precision and smoothness under any load.
• Dynamic Response and Stability: Due to the even load distribution and multiple contact points, the planetary gearbox can provide good dynamic performance, including fast response, stable operation, and durability under heavy loads.
