TNF115 Series High Precision Planetary Gearbox Helical Gear Reducer

Overview

TNF115 Series High Precision Planetary Gearbox Helical Gear Reducer, also known as servo motor planetary gearbox and low backlash planetary gearbox, is a type of high-precision gearbox used in various industrial applications. It is designed to provide accurate and reliable power transmission between two shafts while minimizing backlash and maximizing efficiency.

Basic Construction

1. Sun Gear: located at the center of the planetary gearbox, typically fixed to the input shaft or the housing as a stationary component.
2. Planet Gears: revolving around the sun gear, supported and kept in relative position by the planet carrier. Each planet gear meshes with both the sun gear and the internal gear, sharing and distributing the load when power is inputted.
3. Planet Carrier: a structure with multiple planet gear shaft holes, which carries 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.
4. Ring Gear/Annulus: a large diameter circular gear fixed inside the gearbox housing, with teeth on both inner and outer surfaces meshing with the planet gears. In some applications, it can also function as an input or output end.
5. Bearings and Shaft System: bearings in the high-precision planetary gearbox support the input and output shafts as well as the planet carrier, ensuring stable rotation and smooth operation of all components.
6. Housing: a sturdy structure that encloses all internal components, provides stable support for the gears, protects from external impurities, and may have cooling or lubrication systems.
7. Shafts and Keys: the input and output shafts connect to the sun gear or planet carrier via keys to transmit power and ensure precise torque transfer and axial positioning.
8. Seals: used to prevent lubricant leakage and contamination and ensure cleanliness and good lubrication status inside the gearbox.

Working Principle

1. Torque Transmission and Amplification: when power is transmitted from the input shaft to the sun gear, the sun gear starts to rotate, and the planet gears mesh with both the sun gear and the internal gear, thus beginning to rotate and revolve. Due to the combined effect of multiple sets of planet gears, the load of the entire system is evenly distributed, thereby significantly increasing the output torque and achieving torque amplification.
2. Speed and Gear Ratio Control: by adjusting the tooth number ratio of the sun gear, planet gear, and internal gear, the speed relationship and gear ratio between input and output can be precisely controlled. For example, if the number of planet gears is large or the tooth number difference between the sun gear and internal gear is large, the gear ratio increases, the output speed decreases, and the torque correspondingly increases.
3. Low Backlash Characteristic: high-precision planetary gearboxes specifically focus on reducing or eliminating the clearance between gears, known as "zero/low backlash." This is typically achieved through precision machining, preloading technology, and component selection, ensuring extremely high motion accuracy and smoothness under any load.
4. Dynamic Response and Stability: due to the uniform load distribution and multiple contact points, the planetary gearbox can provide good dynamic performance, including fast response, stable operation, and durability under heavy loads.
