Problems solved by technology

[0002] Due to unavoidable errors in the manufacturing and assembly process of hydrostatic bearings, there is a certain roundness error in the motion trajectory of any point (except the center) on the rotating shaft in the hydrostatic bearing, resulting in There is a certain roundness error when the workpiece or tool rotates. In order to minimize the roundness error, the method of improving the manufacturing and assembly accuracy is generally used at present, but the effect is not ideal.

Embodiment Construction

[0010] A method for adjusting the roundness of a rotating shaft of a hydrostatic bearing, which is characterized in that: changing the local gap between the oil sealing edge and the rotating shaft, so as to change the average gap between the oil sealing edge and the rotating shaft, thereby changing the position of the rotating shaft, adjusting The roundness of the axis of rotation.

[0011] Such as figure 1 , 2 As shown, a hydrostatic bearing device with adjustable roundness of the rotating shaft includes a bearing sleeve 1 and a rotating shaft 3, the gap between the bearing sleeve 1 and the rotating shaft 3 is a static pressure oil chamber 2, and the static pressure oil chamber 2 is equipped with There is an oil sealing edge 4, which is characterized in that: there is an oil sealing edge adjusting pin 5 on the local oil sealing edge 4, which can be used to adjust the gap between the oil sealing edge 4 and the rotating shaft 3, thereby adjusting the average of the oil sealing...

Abstract

The present invention belongs to the field of machinofacture technology, in the concrete, it relates to a regulation method of rotary shaft roundness of hydrostatic bearing and its device. It is characterized by changing local gap between oil-sealing edge and rotary shaft to make the average gap between oil-sealing edge and rotary shaft be changed so as to change the position of rotary shaft and regulate roundness of said rotary shaft. Said device includes the bearing bushing and rotary shaft, the gap between the bearing bushing and rotary shaft is static pressure oil cavity, said static pressure oil cavity has oil-sealing edge, on the local oil-sealing edge an oil-sealing edge regulating pin is set.

Description

technical field [0001] The invention belongs to the category of mechanical manufacturing, in particular to a hydrostatic bearing device with adjustable roundness of a rotating shaft and an adjustment method thereof. Background technique [0002] Due to unavoidable errors in the manufacturing and assembly process of hydrostatic bearings, there is a certain roundness error in the motion trajectory of any point (except the center) on the rotating shaft in the hydrostatic bearing, resulting in There is a certain roundness error when the workpiece or tool rotates. In order to minimize the roundness error, the method of improving the manufacturing and assembly accuracy is generally used at present, but the effect is not ideal. Contents of the invention [0003] The purpose of the present invention is to provide a simple, convenient and ideally effective hydrostatic bearing device with adjustable roundness of the rotating shaft and its adjustment method. [0004] Technical schem...
