Problems solved by technology
[0003] When the bearing clearance is too large, the bearing will move when it rotates, especially when the screw moves to the limit position, which will cause the screw to vibrate; when the bearing clearance is too small, a large amount of heat will be generated due to the rotating work of the bearing, resulting in When the bearing is thermally deformed, the inner ring will be compressed and stuck, unable to follow the rotation of the screw, and the screw will stop working
[0004] The above two situations will cause the antenna to be unable to perform normal pitching actions, which will increase the failure rate of the antenna pitching action and seriously affect the erection and withdrawal of the radar.

The invention relates to a radar pitch transmission system, in particular to a pitch transmission device and a bearing clearance adjustment method thereof. The present invention adopts the method of adding axial backing rings and washers to adjust the axial clearance of the bearing, so as to ensure that when the bearing is working, there is enough room for movement in the axial direction, and no jamming occurs, and it can also avoid excessive gaps and channeling. moving phenomenon. The invention is not only economical in cost, but also convenient in operation, and can improve maintenance efficiency in failure maintenance.
Description
technical field [0001] The invention relates to a radar pitching transmission system, in particular to a pitching transmission device and a bearing clearance adjustment method thereof. Background technique [0002] Radar pitching transmission system is mainly composed of ball screw pair, sealing end cover, sealing gasket, bearing cover, O-ring, tapered roller bearing and main frame frame. When the radar antenna is erected and retracted, it is necessary to drive the ball screw to complete the antenna pitching action. The inner ring of the tapered roller bearing rotates together with the screw, the outer ring is fixed, and the bearing combination adopts a back-to-back assembly method. [0003] When the bearing clearance is too large, the bearing will move during rotation, especially when the screw moves to the limit position, which will cause the screw to shake; The bearing is thermally deformed, and the inner ring will be compressed and stuck, unable to rotate with the lead...
