TEG160 Series High Precision Planetary Gearbox Helical Gear Reducer

Overview of TEG160 Series High Precision Planetary Gearbox Helical Gear Reducer

TEG160 Series High Precision Planetary Gearbox Helical Gear Reducer, also known as servo motor planetary gearbox and low backlash planetary gearbox, is a precision gearbox that is widely used in industrial automation equipment for accurate speed control and position positioning. This gearbox is defined as a compact, high-precision gearbox that offers high torque density and high torsional rigidity with low backlash.

Basic Construction of High Precision Planetary Gearbox

The High Precision Planetary Gearbox consists of the following components:

• 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 relative position by the planet carrier. Each planet gear meshes with the sun gear and the internal gear, and when power is input, they share and distribute the load.
• Planet Carrier: The planet carrier is a structure with multiple planet gear bores, and it carries the planet gears while allowing 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.
• Ring Gear/Annulus: The internal gear is a large-diameter ring gear fixed inside the housing, and it has teeth on both the inner and outer surfaces that mesh with the planet gears. In some applications, the internal gear can also be used as an input or output.
• 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 and Seals: The housing is the external frame of the gearbox, which protects the internal components from external environmental influences and provides mounting interfaces. 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

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

• Torque Transmission: When power is input to the sun gear, the planet gears rotate around the sun gear. Since the planet gears mesh with both the sun gear and the internal gear, they rotate around their own axis 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 on the output end through the planet gears.
• Speed Conversion and Torque Amplification: By adjusting the gear ratio of different components, speed conversion and torque amplification between the 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.
• Low-Backlash Design: In high-precision applications, to ensure accurate position control and minimal mechanical clearance, High Precision Planetary Gearboxes adopt preloading technology to reduce or eliminate the clearance between the gears, which is called "zero/low-backlash" design.
• Load Distribution and Dynamic Response: An important advantage of the planetary gear mechanism is that it can evenly distribute the load between multiple planet gears, thereby improving the bearing capacity and stability of the entire system, and optimizing dynamic response performance.
