TMR115 Series High Precision Planetary Gearbox Helical Gear Reducer

Overview: TMR115 Series High Precision Planetary Gearbox Helical Gear Reducer is a type of gearbox that uses a planetary gear system to achieve high levels of precision. It is known for its low backlash, making it ideal for use in servo motor applications. The TMR115 Series High Precision Planetary Gearbox Helical Gear Reducer is also commonly referred to as servo motor planetary gearbox and low backlash planetary gearbox.

Basic Structure of High Precision Planetary Gearbox

Sun Gear

The sun gear is located in the center of the planetary gearbox and is usually 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 held in their relative positions by the planet carrier. Each planet gear engages with both the sun gear and the ring gear, and when power is input, they collectively bear and distribute the load.

Planet Carrier

The planet carrier is a structure with multiple planet gear shaft holes, which supports the planet gears and allows them to rotate relative to the sun gear. The planet carrier can be used as an output element or connected to another shaft to transmit or receive torque.

Ring Gear/Annulus

The ring gear is a large-diameter annular gear fixed inside the gearbox housing. Both the inside and outside surfaces have teeth that engage with the planet gears. In some applications, the ring gear can also be used 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 of each component.

Housing

The housing is a sturdy structure that encloses all internal components, providing stable support for the gears and protecting the interior from external impurities. It may also include cooling or lubrication systems.

Shafts and Keys

The input and output shafts are connected to the sun gear or the planet carrier through keys to transmit power, ensuring precise torque transmission and axial positioning.

Seals

Seals are used to prevent lubricating oil leakage and the ingress of contaminants into the gearbox, ensuring a clean and well-lubricated interior.

Working Principle of High Precision Planetary Gearbox

The high precision planetary gearbox achieves torque transfer and amplification by distributing the load evenly among the multiple planet gears, which rotate and revolve around the sun gear and the ring gear. The speed and gear ratio of the gearbox can be precisely controlled by adjusting the number of teeth on the sun gear, planet gears, and ring gear. The high precision planetary gearbox is also known for its low backlash, which is achieved through precise processing, preloading technology, and component selection.
