Abstract
The invention discloses the oil recess structure of a kind of hollow shaft type hydrostatic bearing, it is opened on bearing body, it is by a main oil pocket, two auxiliary oil pockets, one repairing chamber, article two, variable cross-section boundling oil duct, multiple oil outlets, a plurality of horizontal oil input channel and a plurality of vertical oil input channel are constituted, main oil pocket is the I shape oil pocket of three row multiple oil outlets in parallel, two auxiliary oil pockets are symmetrical with the main oil pocket two isosceles trapezoid oil pockets arranging multiple oil outlets in parallel, repairing chamber is the rectangle oil pocket of single-row two oil outlets of series connection, each column oil outlet is connected with vertical oil input channel by horizontal oil input channel；The present invention can make that the oil film pressure of hydrostatic bearing is axially distributed uniformly, oil film pressure is big near axle journal lowest point, and from main oil pocket circumferential edge, relatively big along the decay of axle journal circumference oil film pressure, the energy consumption of hydraulic power unit is little, and the bearing capacity of bearing is big；Realizing the all-liquid lubrication that lubricating oil film is complete, operation energy consumption is low.
Description
Technical field
The present invention relates to the oil recess structure of a kind of hydrostatic bearing, particularly to the oil recess structure of a kind of hollow shaft type hydrostatic bearing.
Background technology
The specification of ball mill constantly increases, and the bearing capacity of hydrostatic bearing is proposed requirements at the higher level, and the oil recess structure of existing ball mill hydrostatic bearing, bearing capacity is relatively low, and operation energy consumption is higher.
Summary of the invention
It is an object of the invention to provide the oil recess structure of a kind of hollow shaft type hydrostatic bearing.
The present invention is opened on bearing body, this oil recess structure is made up of a main oil pocket, two auxiliary oil pockets, repairing chamber, two variable cross-section boundling oil ducts, multiple oil outlet, a plurality of horizontal oil input channel and a plurality of vertical oil input channel, main oil pocket is the I shape oil pocket of three row multiple oil outlets in parallel, two auxiliary oil pockets are symmetrical with the main oil pocket two isosceles trapezoid oil pockets arranging multiple oil outlets in parallel, repairing chamber is the rectangle oil pocket of single-row two oil outlets of series connection, and each column oil outlet is connected with vertical oil input channel by horizontal oil input channel.
Beneficial effects of the present invention:
The present invention can make that the oil film pressure of hydrostatic bearing is axially distributed uniformly, oil film pressure is big near axle journal lowest point, and from main oil pocket circumferential edge, relatively big along the decay of axle journal circumference oil film pressure, the energy consumption of hydraulic power unit is little, and the bearing capacity of bearing is big；Realizing the all-liquid lubrication that lubricating oil film is complete, operation energy consumption is low.

Detailed description of the invention
Refer to Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, the present invention is opened on bearing body 10, this oil recess structure is by a main oil pocket 102, two auxiliary oil pockets 103, one repairing chamber 104, article two, variable cross-section boundling oil duct 105, multiple oil outlets 106, a plurality of horizontal oil input channel 107 and vertical oil input channel 108 are constituted, main oil pocket 102 is the I shape oil pocket of three row multiple oil outlets 106 in parallel, two auxiliary oil pockets 103 are symmetrical with the main oil pocket 102 two isosceles trapezoid oil pockets arranging multiple oil outlets 106 in parallel, repairing chamber 104 is the rectangle oil pocket of single-row two oil outlets 106 of series connection, each column oil outlet 106 is connected with vertical oil input channel 108 by horizontal oil input channel 107.
The work process of the present invention is: when ball mill is fully loaded with static; owing to the width of main oil pocket 102 is less than neck of hollow shaft and bearing touch elastic deformation width; by the three row oil circuits in parallel with back pressure function; form main oil pocket 102 and close space, hydraulic oil and bearing body structure shared revolving body that in it, pressure raises and the weight of mixture；When ball mill starting with full load and normal operation, the hydraulic oil of hydraulic power unit is through main oil pocket 102, multiple oil outlets 106 of two auxiliary oil pockets 103 are pressed between neck of hollow shaft and hydrostatic bearing body, revolving body is floated, form complete lubricating oil film, when revolving body rotates, quill shaft rotates and makes the hydraulic oil being adsorbed on axle journal external cylindrical surface move therewith, the lubricating oil film that quill shaft screws in bearing side is thinning, even occur that lubricating oil film is imperfect, two oil outlets 106 that the low pressure oil of hydraulic power unit is connected through repairing chamber 104 flow out, guarantee that lubricating oil film is complete, realize fully liquid lubrication.
