TRHE090 Series High Precision Planetary Gearbox Right Angle Reducer, also known as servo motor planetary gearbox and low backlash planetary gearbox, is a type of gear system used for various industrial automation applications where high precision and low backlash are required.
High Precision Planetary Gearbox consists of:
The sun gear is located at the center of the planetary gearbox, it is usually connected with the input shaft or fixed to the housing as a stationary component.
The planet gears orbit around the sun gear and are supported and maintained in relative position to each other through the planet carrier. Each planet gear meshes simultaneously with the sun gear and the internal ring gear, when power is input, they share and distribute the load.
The planet carrier is a structure with multiple planet gear shaft holes, it carries the planet gears and allows them to rotate relative to the sun gear. The planet carrier can serve as an output element or be linked with another shaft to transmit or receive torque.
The internal ring gear is a large diameter circular gear fixed inside the gearbox housing with teeth on both inner and outer surfaces, it meshes with the planet gears. In some applications, the internal ring gear can also be used as input or output.
The bearings in the high precision planetary gearbox support the input shaft, output shaft, and planet carrier, ensuring stable rotation and smooth operation of all components.
The housing is the external frame of the entire gearbox, it protects the internal components from external environmental influences and provides installation interface. Seals ensure that the internal lubricating grease does not leak while preventing dust and water from entering the gearbox.
High Precision Planetary Gearbox works based on:
When power is input to the sun gear, the planet gears around it rotate. Since the planet gears mesh simultaneously with the sun gear and the internal ring gear, they undergo self-rotation on 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 through the planet gears and evenly distributed to the planet carrier at the output end.
By adjusting the gear ratios of different components, speed conversion between input and output and torque amplification can be achieved. Generally, as the number of planet gears increases or the gear ratio increases, the effect of torque amplification becomes more significant, but the output speed will also decrease.
In high precision applications, to ensure accurate position control and minimal mechanical clearance, high precision planetary gearboxes use preloading technique to decrease or eliminate gear clearance, that is, zero/low backlash design.
An important advantage of the planetary gear mechanism is that it can evenly distribute the load among multiple planet gears, thereby increasing the load capacity and stability of the entire system, and optimizing dynamic response performance.
| Design and Selection Considerations | Explanation |
|---|---|
| Load Characteristics | The type, direction, and magnitude of load, as well as the duration and frequency of operation, should be taken into account when designing and selecting the planetary gearbox. |
| Operating Environment | The temperature, humidity, vibration, shock, and other environmental factors that the gearbox may encounter during use should be considered. |
| Mounting Configuration | The mounting method and structure of the gearbox should be selected based on the installation requirements of the application. |
| Input and Output Requirements | The input and output speed, torque, power, and direction should be matched with the application requirements. |
| Service Life and Maintenance | The service life, maintenance requirements, and spare parts availability of the gearbox should be considered. |
