Planetary gearbox is a necessary mechanical device that can change the speed and output torque. As an important component of mechanical transmission systems, it can be seen in various types of machinery. In the fields of transportation, construction, mechanical processing, etc., from high-speed power devices such as electric motors and internal combustion engines to the working end of power devices, a process of reducing speed and increasing torque is required, and the reducer is the power transmission mechanism that realizes this process. As a company specializing in the production and sales of planetary gearboxes, Shangying Transmission will share with you the relevant knowledge of planetary gearboxes and unveil their mysterious veil.
1、 Overview of planetary gearbox
Planetary GearBox is a type of servo gearbox. It is a mechanical transmission component that connects servo motors and application loads in motion control systems. Planetary reducers have small size, light weight, high load-bearing capacity, long service life, smooth operation, and low noise. It has the characteristics of power splitting and multi tooth meshing for exclusive use. The input power can reach 104kW. It is suitable for industrial sectors such as lifting and transportation, engineering machinery, metallurgy, mining, petrochemicals, construction machinery, light industry and textile, medical equipment, instruments and meters, automobiles, ships, weapons, and aerospace. The planetary series new varieties include WGN fixed axis transmission reducers, WN mother and child gear transmission reducers, and elastic even load low tooth difference reducers.
In the structure of a planetary gear set, there are multiple gears surrounding a central gear along the inner ring of the reducer housing. When the planetary reducer operates, as the central gear rotates, several gears surrounding it will also "revolve" around the central gear. Because the layout of the core transmission part is very similar to the way planets orbit around the sun in the solar system, this type of gearbox is called a "planetary gearbox".
2、 The function of planetary gearbox
1. The use of planetary reducers can effectively maintain the function of the motor. During operation, the reducer receives a large torque, and when overloaded, it is transmitted to the motor as long as the overload amount is divided by the reduction ratio value!
2. To save usage costs, if the motor is directly responsible, it may cause damage to the motor. When the overload is very large, the deceleration machine is first damaged, and the reducer only needs to replace spare parts to restore operation, with relatively low cost. If the motor is directly damaged and repaired, it will be relatively slow and costly.
3. Effectively reducing the moment of inertia, the planetary gearbox can timely control the start stop and speed change. By increasing the torque through the reducer, it is equivalent to increasing the input power, which can reduce the power required by the input motor (in places where speed regulation is required). High power motors are more expensive than low-power motors, so planetary reducers are used to increase torque and save procurement costs.
4. It can effectively save energy by using planetary reducers to reduce the output torque and current of the motor.
5. The use of planetary reducers can effectively reduce the speed and increase the torque of the motor, and output corresponding multiplication and reduction ratios according to the motor.
6. Effectively reducing the load inertia of the motor, in numerical terms, inertia is the square value of the reduction ratio, and the inertia values of different motors are different.
