TNE235 Series High Precision Planetary Gearbox Helical Gear Reducer

TNE235 Series High Precision Planetary Gearbox Helical Gear Reducer Overview

TNE235 Series High Precision Planetary Gearbox Helical Gear Reducer, also known as servo motor planetary gearbox and low backlash planetary gearbox, is a high-precision type of gearbox that is widely used in various industries. It is a type of gearbox that is designed to provide low backlash, high efficiency, high torsional stiffness, and high precision. It is commonly used in applications where high precision is required, such as robotics, medical devices, aerospace, and more.

High Precision Planetary Gearbox Basic Structure

High Precision Planetary Gearbox consists of the following components:

• Sun Gear: Located at the center of the planetary gearbox, it is typically connected to the input shaft or fixed to the housing as a stationary part.
• Planet Gears: Orbit 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 they collectively share and distribute the load when power is input.
• Planet Carrier: A structure with multiple planet gear shaft holes that carries the planet gears and allows them to rotate relative to the sun gear. The planet carrier can act as an output component or be connected with another shaft to transmit or receive torque.
• Ring Gear/Annulus: A large diameter ring gear with teeth on both its inner and outer surfaces 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: Bearings in the high-precision planetary gearbox are used to support the input and output shafts as well as the planet carrier, ensuring stable rotation and smooth operation between the components.
• Housing and Seals: The housing is the outer frame of the entire gearbox, which protects the internal components from external environmental interference and provides mounting interfaces. Seals ensure that the internal grease does not leak and prevent dust and water from entering the gearbox.

Explanation of High Precision Planetary Gearbox Basic Structure Components:

1. The sun gear is the central part of the planetary gearbox and is typically connected to the input shaft or fixed to the housing as a stationary part.
2. The planet gears orbit around the sun gear and mesh with both the sun gear and the ring gear, and they collectively share and distribute the load when power is input.
3. The planet carrier carries the planet gears and allows them to rotate relative to the sun gear. The planet carrier can act as an output component or be connected with another shaft to transmit or receive torque.
4. The ring gear 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.
5. Bearings in the high-precision planetary gearbox are used to support the input and output shafts as well as the planet carrier, ensuring stable rotation and smooth operation between the components.
6. The housing is the outer frame of the entire gearbox, which protects the internal components from external environmental interference and provides mounting interfaces. Seals ensure that the internal grease does not leak and prevent dust and water from entering the gearbox.

Working Principle of High Precision Planetary Gearbox

The working principle of the High Precision Planetary Gearbox is as follows:

1. Torque Transmission: When power is input to the sun gear, it drives the surrounding planet gears to rotate. Because the planet gears mesh with both the sun gear and the ring gear, they rotate around themselves while revolving around the center of the sun gear by means of the planet carrier. In this way, the torque input to the sun gear is amplified by the planet gears and evenly distributed to the planet carrier at the output end.
2. Speed Conversion and Torque Amplification: By adjusting the tooth 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 also decreases.
3. Low Backlash Design: In high-precision applications, to ensure accurate position control and minimal mechanical clearance, high-precision planetary gearboxes use preloading technology to reduce or eliminate the gap between gears, i.e. "zero/low backlash" design.
4. Load Distribution and Dynamic Response: An important advantage of planetary gear mechanisms is that they can distribute the load evenly among multiple planet gears, thus improving the load-carrying capacity and stability of the entire system and optimizing dynamic response performance.
