According to the notice from the State Intellectual Property Office of the People's Republic of China on March 12, the new bearing life reliability testing machine developed by Zhejiang BH Bearing Co., Ltd has been issued the patent of invention.
Now with the increasing demand of bearing life reliability by the main machine, it is quite necessary to make relevant test for bearing to ensure its life reliability, especially for the train, automotive, motor vehicle bearings which with the demand of "zero defect", thus to make test before entering the supplying system is indispensable. However, tests made by customers mainly aimed at the entire machine, so it is difficult to make objective & accurate evaluation for bearings to clarify the failure mode. In the meanwhile, most of the existing bearing test machines belong to the enhancement test under the standard test conditions.
Therefore, Zhejiang BH Bearing Co., Ltd designed this type of bearing life reliability testing machine according to the main machine's working conditions and users requirements, which has broken the bearing standard testing mode, meanwhile made tests for the simulation main machine's load, speed, environmental temperature and other variable working condtions. Consequently, it could find out bearings' weakness after had been tested, thus to make further improvement and commitment to the "zero defect" promise for the main machines. Additionally, this testing machine could not only adopted by Zhejiang BH Bearing Co., Ltd, but also selling to other manufacturers for them to make specialised test.
It is said that another machine tool bearing developed by Zhejiang BH Bearing Co., Ltd has also issued the utility model patent in recent days.
