Heyuan city, guangzhou auto parts manufacturers remain the same

Heyuan city, guangzhou auto parts manufacturers to keep the secret of the same car high precision bearing the fundamental safeguard measures is to ensure the accuracy of bearing. Before installation, bearing application of gasoline or kerosene cleaning, dry and plentiful smooth before use. Usually, auto bearing with grease or oil is smooth. Use of grease is smooth, should choose the impurities, antioxidant, antirust and extreme pressure properties such as good fats. Smooth grease filling amount shall be the high temperature bearing and bearing housing - 30% of the volume 60%, and should not be too much. Smooth seal structure of automobile bearing has been filled with grease, users can directly use, can't again to clean. Gear bearing, necessary on the circumference of the ring width equal to the pressure, to press the ring into, and don't knock bearing face directly with a hammer or other tools, so as to avoid damage to the bearings. 。 In smaller interference conditions, with the sleeve bearing ring end face to in room temperature compression, with a hammer percussion sleeve, and then through the clamping ring on the sleeve will average pressure. If is bulk device that can use the hydraulic press. Fashionable, please make sure that shoulder end face pressed into the outer end face and the shell and the inner ring end face and shoulder end face, there is no gap. ( 1) The size of the measurement of shaft and bearing hole, to sure bearing matching precision. Match the request as follows: the inner ring and the shaft by interference fit, 0 - interference + 4μ m( When light load is 0, high precision) ; Outer ring and the bearing holes are clearance, clearance volume of 0 - + 6μ M( But at the free end use as bearings, angular contact ball bearing clearance can also increase) ; Shaft with a hole between appearance of roundness error is less than 2 & mu; M, used in automobile bearing the gasket face of parallelism is less than 2 & mu; M, shoulder the beats and the outer end face of shaft shoulder end in less than 2 & mu; m。 Bearing hole of the fixed axis shoulder related to beat is less than 4 & mu; m; Spindle front end related to the axis of the dance within less than 4 & mu; M。 ( 2) The front bearing device in shaft fixed end: clean thoroughly with clean clean kerosene auto bearing. About the grease is smooth, will contain 3% 5% fat organic solvents into the bearing to stop degreasing and cleaning, and then quantitative grease injection oil gun will bearing ( Accounting for 10% of the bearing space? 15%) 。 ) ; Heat the bearing temperature rise 20? 30 ℃, the bearing device with hydraulic press to the shaft end. To press the fastening sleeve on the shaft, and in the proper pressure bearing face, make its axial positioning. Will spring balance belt scroll to bearing's outer ring, and through the measurement of starting torque to check whether the specified pre-tightening force have obvious changes, Even double row deep groove ball bearing is right, but also because of the joint or pretightening frame deformation) 。 In an article: guangzhou shantou bearing manufacturer jointly explore precision processing method to the next: guangzhou shanwei cities about bearing rust measures bearing manufacturer
