Application of Internal Feedback Round Table Throttle in Static Pressure Bearing
The internal feedback throttle hydrostatic bearing has the advantages of high oil film stiffness, not easy to block, and bearing performance is not affected by bearing clearance. Disadvantages are long bearing lengths and high frictional power consumption. Xia Hengqing proposed a new structure for the circular table throttling chamber, placing the truncated cone restrictor on the circumferential sealing surface of the bearing to minimize the size of the throttling cavity supported by the internal throttling, thereby overcoming its shortcomings and making the internal throttling The advantages of the support are fully utilized.
