TM115 Series High Precision Planetary Gearbox Helical Gear Reducer, also known as servo motor planetary gearbox and low backlash planetary gearbox, is a type of gearbox that is widely used in various industries. It is designed to achieve high precision, low noise, and high efficiency in power transmission.
High Precision Planetary Gearbox consists of six main components: Sun Gear, Planet Gears, Planet Carrier, Ring Gear/Annulus, Bearings and Shaft System, and Housing and Seals.
The sun gear is usually located at the center of the planetary gearbox and is connected to the input shaft or fixed to the housing as a stationary component.
The planet gears orbit around the sun gear and are supported and held in position relative to each other by the planet carrier. Each planet gear meshes 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 supports the planet gears and allows them to rotate relative to the sun gear. The planet carrier can be used as an output element or connected to another shaft to transmit or receive torque.
The ring gear/annulus is a large diameter ring gear fixed inside the housing with teeth on both the 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.
The bearings in the high-precision planetary gearbox support the input shaft, output shaft, and planet carrier, ensuring stable rotation and smooth operation between the components.
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 lubricating grease does not leak and prevent dust and water from entering the gearbox.
The working principle of high-precision planetary gearbox is mainly based on torque transmission, speed conversion and torque amplification, low backlash design, and load distribution and dynamic response.
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 ring 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 magnified by the planet gears and evenly distributed to the output end's planet carrier.
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 or gear ratio increases, the effect of torque amplification becomes more significant, but the output speed decreases simultaneously.
In high-precision applications, to ensure accurate position control and minimum mechanical clearance, high-precision planetary gearboxes use preloading technology to reduce or eliminate gear clearances, known as "zero/low backlash" design.
One of the essential advantages of planetary gear mechanisms is that they can distribute loads evenly among multiple planet gears, thereby improving the entire system's load capacity and stability and optimizing dynamic response performance.
The design and selection of high-precision planetary gearbox should take into account several factors, including:
| Factors | Explanation |
|---|---|
| Application requirements | What are the specific application requirements, such as precision, speed, torque, and noise? |
| Load characteristics | What are the load characteristics, such as constant or intermittent loads, and what is the load distribution among the planet gears? |
| Environmental conditions | What are the environmental conditions, such as temperature, humidity, and dust, that the gearbox will operate under? |
| Mounting position and interface | What is the mounting position and interface of the gearbox, and what are the space and installation requirements? |
| Cost and maintenance | What is the budget for the gearbox, and what are the maintenance requirements and costs? |
