Contact angle is an important parament to determine the bearing's performance, and it determines the axial and radial bearing capacity of the bearing. Large amount of theoretical researchs and experiments show that the contact angle value and its consistency will directly affect the rigidity, rotating accuracy and life of the whole shafting on angular contact ball bearing for precision spindle, especially duplex bearings. Therefore more and more users have controlled this parameters strictly as a key factor which can improve the performance of precison spindle.
The contact angular measuring instrument we developed applies planetary gear train principle, namely which is that fixing inner ring, balls and outer ring rotation at a certain ratio. The ratio is a function of bearing contact angle. By setting the rotational speed of cage, the instrument measures corresponding rotational speed of outside ring. After processed by the computer, it can show the contact angle value.
This instrument is easy to operate, and has high precision and good repeatability. It is applicable to host matchment measurement or national metrology unit.
