What is Reducer bearing

A reducer is an independent component composed of a gear drive, worm drive, and gear worm drive enclosed in a rigid housing. It is commonly used as a reduction transmission device between the prime mover and the working machine. Widely used in various mechanical equipment. The reducer bearing of the gearbox is an important component of the gearbox, and all types of reducers cannot do without the bearing. Its main function is to support the rotating components of the gearbox, while also bearing large loads and impact forces. On the one hand, it is to keep the gear lubricating oil inside the bearing from losing during use, and on the other hand, it is to protect the dust or harmful gases outside the bearing from entering the bearing cavity.

Features of reducer bearing

Therefore, the bearings of the gearbox need to have the following performance characteristics:

1. High load-bearing capacity

The bearings of the gearbox need to have high load-bearing capacity and be able to withstand large radial and axial loads. In order to improve the load-bearing capacity of bearings, rolling element bearings are usually used, such as ball bearings, tapered roller bearings, self-aligning roller bearings, etc.

2. Good wear resistance

The bearings of the gearbox need to have good wear resistance and be able to maintain stable performance during long-term operation. In order to improve the wear resistance of bearings, high-strength materials such as high carbon chromium steel, stainless steel, etc. are usually used.

3. High precision and stability

The bearings of the gearbox need to have high accuracy and stability, which can ensure the operational accuracy and stability of the gearbox. In order to improve the accuracy and stability of bearings, precision machining processes and high-quality materials are usually used.

4. Good sealing performance

The bearings of the gearbox need to have good sealing performance, which can prevent impurities such as dust and moisture from entering the interior of the bearings and affecting their normal operation. In order to improve the sealing performance of bearings, sealing structures such as rubber sealing rings, metal sealing rings, etc. are usually used.

In summary, the bearings of the gearbox need to have high load-bearing capacity, good wear resistance, high accuracy and stability, and good sealing performance. When selecting a reducer, appropriate bearings should be selected based on actual needs to ensure the performance and lifespan of the reducer.

The centripetal bearing of the gearbox mainly bears larger radial loads and a portion of smaller axial loads, while the thrust bearing of the gearbox bears larger axial loads and smaller radial loads.

Load size and nature: Ball bearings should be used for light and medium loads; Roller bearings should be selected for heavy or impact loads.

Load direction: For pure radial loads, deep groove ball bearings or cylindrical roller bearings can be selected. Thrust bearings can be selected for pure axial loads. When there is both radial load and bearing load, if the axial load is not large, deep groove ball bearings or angular contact bearings with smaller contact angles or tapered roller bearings can be selected; If the axial load is large, these two types of bearings with larger contact angles can be selected; If the axial load is large and the radial load is small, thrust angular contact bearings can be selected, or a support structure combining radial bearings and radial bearings can be used.

Application of reducer bearings

Robot reducers have the characteristics of high precision, high rigidity, high load, high speed ratio, long service life, low inertia, low vibration, low noise, low temperature rise, compact structure, and simple installation. Currently, there are two main types of robot reducers used in the field: harmonic reducers and RV reducers.
