TNR090 Series High Precision Planetary Gearbox Helical Gear Reducer

Overview

TNR090 Series High Precision Planetary Gearbox Helical Gear Reducer is a type of gearbox that is used to reduce the speed and increase the torque of a motor or engine. It is also known as servo motor planetary gearbox and low backlash planetary gearbox. This gearbox is widely used in various industries for its high precision and low backlash features.

Basic Construction

High Precision Planetary Gearbox consists of the following parts:

1.Sun Gear

Sun Gear is located at the center of the planetary gearbox and is usually connected to the input shaft or fixed on the housing as a stationary component.

2.Planet Gears

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 the Sun Gear and the Ring Gear/Annulus, 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 axle holes that carries 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/Annulus is a large-diameter ring-shaped gear fixed inside the housing with teeth on both inner and outer surfaces that mesh with the Planet Gears. In some applications, the Ring Gear/Annulus can also be used as an input or output end.

5.Bearings and Shaft System

The bearings in High Precision Planetary Gearbox are used to support the input shaft, output shaft, and Planet Carrier, ensuring stable rotation and smooth operation between components.

6.Housing and Seals

The housing is the external frame of the entire gearbox, which 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 water from entering the gearbox.Here's an image of Servo Motor Planetary Gearbox:

Working Principle

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

1.Torque Transmission

When power is input to the Sun Gear, the Planet Gears surrounding it rotate. Since the Planet Gears mesh with both the Sun Gear and the Ring Gear/Annulus, they spin around their own axis and revolve 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 onto the Planet Carrier at the output end.

2.Speed Conversion and Torque Amplification

By adjusting the gear ratio of different components, speed conversion and torque amplification can be achieved between input and output. Generally, as the number of Planet Gears or the gear ratio increases, the effect of torque amplification becomes more significant, but the output speed also decreases.

3.Low Backlash Design

In high-precision applications, in order to ensure accurate position control and minimum mechanical clearance, high-precision planetary gearboxes use preload technology to reduce or eliminate gear clearance, i.e., "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 increasing the bearing capacity and stability of the entire system, and optimizing dynamic response performance.

Design and Selection Considerations

Design and selection considerations for High Precision Planetary Gearbox are as follows:

Consideration	Description
Load capacity	The gearbox must be able to withstand the maximum load of the application.
Backlash	The gearbox must have low or zero-backlash to ensure accurate positioning and smooth operation.
Ratio	The gear ratio determines the output speed and torque.
Efficiency	The efficiency of the gearbox affects the power consumption of the system.
Lubrication	The gearbox must be properly lubricated to prevent wear and tear of the components.
