Unlike other cylindrical bore radial bearings; the internal clearance of single row angular contact ball bearings and tapered roller bearings; as long as one bearing is aligned with another bearing for adjustment. Usually these bearings are back-to-back or face-to-face pairing; The bearing ring is axially displaced; until the selected clearance or preload is reached. The clearance or preload is selected; depending on the function and working conditions of the bearing plan. Thus; the following claims only touch the angular touch ball bearing Internal clearance adjustment for bearing planning of tapered roller bearings. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The device should reach the proper clearance value; it can be determined according to the bearing load and working temperature. According to the bearing scale and planning, the shaft and bearing housing production materials and the spacing between the two bearings; The gap may become smaller or larger in practice. For example, the thermal expansion of the inner and outer rings may form a contraction of the working gap. Huan.
Because there is a clear connection between the radial and axial internal clearances of the angular touch ball bearing and the tapered roller bearing; so; just specify a value. Usually specify the axial internal clearance. Then pass The following method takes the specified value from the zero clearance condition: loosening or tightening the nut on the shaft or the screw ring in the shaft hole of the housing; or piercing a calibrated washer or pad between a bearing ring and its seat Piece. A practical method for adjusting the clearance and measuring the setting clearance; depending on the number of bearings to be mounted.
For example; one way is to use a dial gauge mounted on the hub; look at the set axial clearance of the hub bearing plan. It is important; when adjusting the tapered roller bearing and measuring the clearance; the shaft or bearing housing needs to Rotate in different directions for several weeks; to ensure proper contact between the end of the ball and the leading edge of the inner ring. If the touch is not appropriate; the measurement results are not accurate; the expected adjustment intention cannot be reached.
