First, working principle

Cycloidal pin gear reducer is a novel transmission device that applies the principle of planetary transmission and adopts the meshing of cycloidal pin teeth.

The overall structure is divided into input part, deceleration part and output part.

Second, structural features

1. The cycloidal pinwheel reducer has a high reduction ratio and high transmission efficiency: the reduction ratio of the first-stage transmission is 9-87, and the reduction ratio of the two-stage transmission is 121-5133. The multi-stage combination can reach tens of thousands, and the pin-tooth engagement system sets Type rolling friction, no relative sliding on the meshing surface, so the first-stage deceleration efficiency reaches 94%:

2. Due to the planetary transmission principle of the cycloid pinwheel reducer, the input and output shafts are on the same axis, with compact structure and small size. Compared with other reducers of the same power, the weight and volume are more than 1/3 smaller.

3. The cycloidal pinwheel reducer moves smoothly and has low noise: there are many teeth in contact at the same time during operation, the degree of coincidence is large, the operation is stable, the overload capacity is strong, and the vibration and noise are low.

4. Reliable use and long life. The main material is made of bearing steel, which is quenched (HRC58-62) and then finely ground. There is no relative sliding in the meshing area, with minimal wear and durability.

5. Reasonable design, convenient maintenance, easy to disassemble and install.

6. Strong overload capacity, impact resistance, small moment of inertia, suitable for occasions with frequent starting and forward and reverse rotation.

7. The reducer has no self-locking function, the output shaft cannot bear the axial force, and the overload protection device should be installed in the use occasions where overload may occur.

8. When a coupling is used to connect the cycloid reducer with the matching machinery, it is recommended to use an elastic coupling.

Third, product category

Commonly used series of cycloid reducer are B series and X series;

Installation methods include foot installation (W horizontal) and flange installation (L vertical)

The B series cycloidal pinwheel reducer and the X series cycloidal pinwheel reducer are not a series of products, but are produced according to different standards: the B series are produced according to the standards promulgated by the national chemical department, and the X series are produced according to the national machinery department Promulgated standard production. But the carrying capacity and output torque of the respective models of the two are the same, but the size and installation method are somewhat different.

The standard installation method is shown below:

The difference between the direct motor type and the ordinary motor type: the motor direct connection is a customized motor integrated with the reducer; the ordinary motor type refers to the national standard motor, which is connected to the reducer through a flange, and the motor is easy to replace.
