Why do RV reducers use two cycloidal gears?

Why do RV reducers use two cycloidal gears?

2024-10-06

Two cycloidal gears mesh with each other inside the needle wheel, forming a closed transmission system. When the input shaft rotates, the planetary gear drives the cycloidal gear to rotate, and the meshing point between the cycloidal gear and the needle wheel constantly changes, thus achieving the functions of deceleration and power transmission. In summary, the RV reducer uses two cycloidal gears to improve load-bearing capacity, balance radial forces, enhance transmission accuracy, and facilitate installation and adjustment. Its working principle is to convert the high-speed rotation of the input shaft into low-speed rotation of the output shaft through the meshing of planetary gears and cycloidal pinwheels.

In order to reduce additional losses, the rotor core of a permanent magnet DC brushed motor is made of stacked silicon steel sheets with a thickness of 0.35mm to 1.0mm, and rotor slots are punched out on the core. The rotor slot is embedded with windings and connected to a mechanical commutator. The mechanical commutator continuously and regularly changes the direction of the current in the rotor winding, thereby changing the magnetic properties of the winding poles and interacting with the stator permanent magnets to rotate the rotor.

It should be noted that when disassembling the worm gear reducer, it is necessary to follow the correct operating steps to ensure safety and correctness. If unsure how to disassemble the gearbox, it is recommended to refer to relevant technical information or consult a professional.

The problem of broken shafts caused by different concentricity

The problem of broken shafts caused by different concentricity

2024-09-29

From the perspective of assembly technology, if the drive motor shaft and the input end of the reducer are concentric, the contact surface between the drive motor shaft and the input end hole of the reducer will be very close, with no radial force or deformation space. If the assembly is not concentric, there will be a mismatch or gap between the contact surfaces, resulting in radial force and providing space for deformation. Similarly, the output shaft of the gearbox also experiences breakage or bending, which is caused by the same reasons as the shaft breakage of the drive motor. But the output of the reducer is the product of the output of the driving motor and the reduction ratio, and the output is larger compared to the motor, so the output shaft of the reducer is more prone to breakage. Therefore, when using the reducer, users should pay more attention to ensuring the concentricity of its output end assembly!

That's all for the related content. High temperature may seem like a simple and small problem, but in reality, it can cause big problems. Not only does it affect the efficiency of the planetary gear reducer, but in severe cases, it can even damage the internal gear structure of the planetary gear reducer, accelerate gear damage, and seal aging.

High quality components such as gears and bearings not only have better wear resistance and load-bearing capacity, but also reduce friction losses and improve the overall performance of the gearbox. In addition, adopting an efficient lubrication system can reduce the friction coefficient and further enhance the energy-saving effect.
