Description
Technical field
This utility model relates to the dynamic and hydrostatic bearing technical field that thrust is placed in two ends, is specially a kind of dynamic and hydrostatic bearing that thrust is placed in two ends。
Background technology
At present, bearing for grinding wheel spindle of grinder mainly selects hydrodynamic bearing or hydrostatic bearing, the bearing of part high-precision grinder main shaft then adopts sound bearing, and the oil recess structure form of such dynamic and hydrostatic bearing is laying of being staggered in the axial direction in dynamic pressure cavity and static pressure chamber, so, before entering normal operation operating mode, utilize the static pressure effect in static pressure chamber to carry external applied load, when entering normal operation operating mode, close the pressure oil in static pressure chamber, external applied load is carried by the dynamic pressure of dynamic pressure cavity, the bearing of this version is the simple combination mode of dynamic pressure and static pressure, functionally not compound, structure is complicated and bearing capacity is not enough, traditional dynamic and hydrostatic bearing can not two ends stress, stressed effect is bad。
Utility model content
The purpose of this utility model is in that to provide a kind of dynamic and hydrostatic bearing that thrust is placed in two ends, with the problem solving to propose in above-mentioned background technology。
For achieving the above object, this utility model provides following technical scheme: a kind of dynamic and hydrostatic bearing that thrust is placed in two ends, including dynamic and hydrostatic bearing, actuating device and pad, described dynamic and hydrostatic bearing includes inner bearing and outer bearing, and it is respectively sleeved on outer bearing outside the two ends of inner bearing, the medial surface of described outer bearing is provided with fixing hole, the middle part outer sheath of described inner bearing is connected to actuating device, described actuating device includes fixed block and power transmission shaft, and fixed block be respectively arranged at two ends with power transmission shaft, the outer surface of described power transmission shaft is provided with driving hole, it is provided with pad between described power transmission shaft and outer bearing, and pad is provided with through hole, run through in described through hole and be provided with driving member, one end of described driving member is fixed in driving hole, and the other end of driving member is fixed in fixing hole。
Preferably, described driving member is equidistant to be applied on pad, and quantity is at least 12。
Preferably, described pad respectively and leaves the distance of 0.5. millimeter to 1 millimeter between outer bearing and power transmission shaft。
Compared with prior art, the beneficial effects of the utility model are: this utility model by being provided with actuating device on dynamic and hydrostatic bearing, when there being External Force Acting on actuating device, power transmission shaft drives driving member to rotate, so that outer bearing rotates, and the external force that now two ends of dynamic and hydrostatic bearing are rotated, axle with dynamic bearing two ends rotates, this utility model simple in construction, makes dynamic and hydrostatic bearing two ends stress, easy to use。
Accompanying drawing explanation
