TRHE110 Series High Precision Planetary Gearbox Right Angle Reducer

Overview of TRHE110 Series High Precision Planetary Gearbox Right Angle Reducer

The TRHE110 Series High Precision Planetary Gearbox Right Angle Reducer, also known as the servo motor planetary gearbox or low backlash planetary gearbox, is a precision gearbox commonly used in industrial automation equipment, medical equipment, aerospace, and precision instruments. It is designed to provide high precision, high torque, and low backlash in a compact form factor.

Basic Construction of High Precision Planetary Gearbox

1. Sun Gear: The sun gear is located at the center of the planetary gearbox and is usually connected to the input shaft or fixed to the housing as a stationary component.
2. Planet Gears: The planet gears rotate 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, and together they share and distribute the load when power is input.
3. 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 component 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, with teeth on both its inner and outer surfaces 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 of the components.
6. Housing and Seals: The housing is the external frame of the gearbox, which protects the internal components from environmental influences and provides installation interfaces. The seals ensure that the internal lubricant does not leak and prevent dust and water from entering the gearbox.

Working Principle of High Precision Planetary Gearbox

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 on their own axes while revolving around the center of the sun gear with the planet carrier. In this way, the torque input to the sun gear is amplified and evenly distributed to the planet carrier at the output end through the planet gears.
2. Speed Conversion and Torque Amplification: By adjusting the gear ratio of different components, speed conversion and torque amplification between input and output can be achieved. Generally, when the number of planet gears increases or the gear ratio increases, the effect of torque amplification is more significant, but the output speed will also decrease.
3. Low Backlash Design: In high precision applications, to ensure precise position control and minimal mechanical clearance, high precision planetary gearboxes use preload technology to reduce or eliminate the clearance between gears, which is known as "zero/low backlash" design.
4. Load Distribution and Dynamic Response: An important advantage of the planetary gear mechanism is that it can evenly distribute the load among multiple planet gears, thereby improving the overall load-bearing capacity and stability of the system, and optimizing dynamic response performance.
