Development Of Electromagnetic Clutch Bearing In Automobile Air-conditioner Comperessor

Air-conditioner is one of the important auxiliary equipments in automobile application. The structure and functions of double row angular contact ball bearings for electromagnetic clutch in air-conditioner will directly influence the performance of the compressor.On the base of design technology researching , this paper describes the optimum design of typical double row angular contact ball bearings in electromagnetic clutch, its processing key technology and measurements. In addition, the bearing developed has been comparablely measured and tested with the same type advanced international ones, the results show that the life and performance of the bearing developed in this paper are almost the same as the international advanced ones.Followings are the innovative conclusions.1. Analytic expression of angular clearance and geometry strurure parpmeters is derived for bearing design;2. Analytic relationships among radial clearance, axial clearance, contact angle, center distance between two grooves, and bearing fit gap are derived for bearing design;3. Analytic relations of radial fit gap and radial clearance is derived for bearing production.These innovative conclusions are important guidelines for designing other type double row angular contact ball bearings.
