TM090 Series High Precision Planetary Gearbox Helical Gear Reducer

Overview of TM090 Series High Precision Planetary Gearbox Helical Gear Reducer

TM090 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 widely used in various industries. It is a highly precise gearbox that features high gear ratios, low backlash, and high torque density, making it an ideal solution for applications that require high precision and efficient power transmission.

Basic Construction of High Precision Planetary Gearbox

The High Precision Planetary Gearbox consists of the following components:

• Sun Gear: The central gear of the gearbox that is usually connected to the input shaft or fixed in the housing as a stationary component.
• Planet Gears: The gears that rotate around the sun gear and are supported and positioned relative to each other by the carrier. Each planet gear meshes with both the sun gear and the ring gear, and together they share and distribute the load when power is input.
• Planet Carrier: The structure with multiple planet gear shaft holes that supports the planet gears and allows them to rotate relative to the sun gear. The planet carrier can act as an output element or be connected with another shaft to transmit or receive torque.
• Ring Gear/Annulus: The large diameter circular gear that is fixed inside the housing and meshes with the planet gears. In some applications, the ring gear can also act as an input or output end.
• Bearings and Shaft System: The bearings in the high precision planetary gearbox support the input shaft, output shaft, and the planet carrier to ensure stable rotation and smooth operation of the components.
• Housing and Seals: The housing is the external framework of the gearbox that protects the internal components from external environmental influences and provides installation interfaces. Seals ensure that the internal lubricant does not leak and prevent dust and moisture from entering the gearbox.

Working Principle of High Precision Planetary Gearbox

The High Precision Planetary Gearbox works based on the following principles:

1. Torque Transmission: When power is input to the sun gear, it drives the planet gears around it. Since the planet gears mesh with both the sun gear and the ring gear, they rotate around their own axis while revolving around the center of the sun gear with the carrier. This amplifies the torque input to the sun gear and distributes it evenly to the planet carrier on the output end.
2. Speed Conversion and Torque Amplification: By adjusting the gear ratios of different components, speed conversion and torque amplification between the input and output can be achieved. Generally, increasing the number of planet gears or gear ratios results in greater torque amplification but lowers the output speed.
3. Low Backlash Design: In high precision applications, the High Precision Planetary Gearbox uses preloading technology to reduce or eliminate the backlash between gears, known as a "zero/low backlash" design, to ensure precise position control and minimal mechanical clearance.
4. Load Distribution and Dynamic Response: One of the significant advantages of the planetary gear mechanism is that it can distribute the load evenly among multiple planet gears, thereby improving the load-bearing capacity and stability of the entire system, and optimizing dynamic response performance.
