Overview of TM090 Series High Precision Planetary Gearbox Helical Gear Reducer

TM090 Series High Precision Planetary Gearbox Helical Gear Reducer is a type of gearbox that serves as a speed reducer and torque amplifier. It is also known as servo motor planetary gearbox and low backlash planetary gearbox. This gearbox is commonly used in industrial automation equipment for precise speed control and accurate positioning. It is designed to provide high precision, low backlash, and maximum efficiency in motion control applications.

Basic Structure of High Precision Planetary Gearbox

The basic structure of a High Precision Planetary Gearbox consists of the following components:

1. Sun Gear: Located in the center of the gearbox, it is usually connected to the input shaft or fixed to the housing as a static component.
2. Planet Gears: These gears revolve around the sun gear and are supported and held in relative position to each other by the planet carrier. Each planet gear meshes with both the sun gear and the ring gear to carry and distribute the load when power is inputted.
3. Planet Carrier: It 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 be used as an output element or connected to another shaft to transmit or receive torque.
4. Ring Gear/Annulus: The ring gear is a large diameter circular gear fixed inside the housing. Its inner and outer surfaces have teeth that mesh with the planet gears. In some applications, the ring gear can also be used as an input or output end.
5. Bearings and Shaft System: The bearings in the high precision planetary gearbox support the input shaft, output shaft, and planet carrier, ensuring stable rotation and smooth operation between all components.
6. Housing: The housing is a sturdy structure that encloses all internal components and provides a stable support environment for gears. It also protects the internal components from external impurities and may include cooling or lubrication systems.
7. Shafts and Keys: The input and output shafts are connected to the sun gear or planet carrier through keys to transmit power and ensure precise torque transmission and axial positioning.
8. Seals: Seals prevent lubricating oil leakage and contamination from entering the gearbox, ensuring internal cleanliness and good lubrication.

Working Principle of High Precision Planetary Gearbox

The working principle of a High Precision Planetary Gearbox involves the following:

1. Torque Transmission and Amplification: When power is transmitted from the input shaft to the sun gear, it starts to rotate. Since the planet gears mesh with the sun gear and the ring gear simultaneously, they start rotating and revolving. Due to the combined action of multiple sets of planet gears, the load of the entire system is evenly distributed, which significantly increases the torque at the output end, achieving torque amplification.
2. Control of Speed and Transmission Ratio: By adjusting the tooth number ratio between the sun gear, planet gears, and ring gear, the speed relationship and transmission ratio between the input and output can be precisely controlled. For example, if there are more planet gears or a larger difference in the number of teeth between the sun gear and the ring gear, the transmission ratio increases, the output speed decreases, and the torque correspondingly increases.
3. Low Backlash Feature: High Precision Planetary Gearboxes are specially designed to reduce or eliminate the gear backlash, known as "zero/low backlash." This is typically achieved through precision machining, preloading techniques, and component selection, ensuring high motion accuracy and smoothness under any load.
4. Dynamic Response and Stability: Due to the evenly distributed load and multiple contact points, planetary gearboxes provide good dynamic performance, including fast response, stable operation, and durability under heavy loads.
