Introduces the main structure of the test machine

Introduces the main structure of the test machine, transmission, and test systems. B8-2 5 bearing life testing machine test range is 8 ~ 2 5mm diameter lubricating oil or grease lubricated bearings, the maximum test speed of up to 2 40 0 ​​0r min, the entire testing process automatically by a computer monitor
As in recent years, cars, motorcycles and household appliances industry continues to develop, the industry's need for increasingly demanding high quality bearings, bearing life and performance quality in the position of the bearing is also becoming increasingly important. In order to adapt to this development, we have developed a new bearing life testing machine B8-2 5, the test machine to meet the high speed test bearings miniature bearings, especially high-speed test requirementsMany different types of rolling bearings, the choice may consider the following factors, which to choose.
1. Payload size, direction and nature: ball bearings suitable for light load to bear, roller bearings suitable for heavy load and impact load. When subjected to pure axial load bearing, thrust bearing is generally used; when rolling under pure radial load, generally used in deep groove ball bearings or cylindrical roller taper roller bearing  when rolling under pure radial load at the same time, there is little axial load, the choice of deep groove ball bearings, angular contact ball bearings, tapered roller bearings and self-aligning ball or spherical roller bearings; when the axial load is large, the choice of the contact angle larger angular contact ball bearings and tapered roller bearings, or use radial bearings and thrust bearings together, which in very high axial loads or special requests, especially when there are large axial rigidity adapt appropriate.
2. Permissible speed: Due to different types of bearings are very different. Generally, the friction is small, less heat bearing suitable for high speeds. Rolling in the design should strive to lower the speed limit working conditions.
