Abstract
The invention discloses a novel bearing body of a hollow axial hydrostatic bearing. The bearing body is provided with an oil cavity, two coherent oil channels, a hole with a surface less than a half of an inner cylindrical surface, an axial lightening hole, a transverse lightening hole, and a plurality of reinforcing ribs, wherein the transverse lightening hole is vertical to the axial lightening hole, the oil cavity comprises a main oil cavity, two auxiliary oil cavities and an oil supplementing cavity, the main oil cavity is an I-shaped oil cavity with a plurality of oil outlets connected in parallel in three columns, the two auxiliary oil cavities are isosceles trapezoid oil cavities which are provided with a plurality of oil outlets connected in parallel in two columns and are symmetric with the main oil cavity, the oil supplementing cavity is a rectangular oil cavity with double oil outlets connected in series in one column, the bearing body is provided with a plurality of horizontal oil inlet passages and vertical oil inlet passages, and the oil outlets in each column are communicated with the vertical oil inlet passages through the horizontal oil inlet passages, The bearing body disclosed by the invention is good in aligning performance and large in ratio of strength to weight; and the structure form of the oil cavity is beneficial to formation of oil film pressure distribution in a semi-circle sine curve along the peripheral direction, the form of the oil outlets and the coherent oil channels is beneficial to formation of an oil film with uniform axial pressure, and the bearing capacity of the bearing body is large.
Description
Technical field
The present invention relates to a kind of bearing support of hydrostatic bearing, particularly a kind of bearing body of hollow shaft type hydrostatic bearing.
Background technique
The specification of pebble mill constantly increases, and improves constantly the requirement of the bearing capacity of hydrostatic bearing, and the structural type of bearing support aligning performance, bearing support strength and stiffness and upper oil cavitie thereof is most important.
Summary of the invention
The object of this invention is to provide a kind of bearing body machine of hollow shaft type hydrostatic bearing.
The bearing support of the present invention has oil pocket, two boundling oil ducts, be less than semicolumn face groove, axial lightening hole, horizontal lightening hole and many stiffening ribs, horizontal lightening hole is vertical with axial lightening hole; Oil pocket is made up of a main oil pocket, two auxiliary oil pockets and a repairing chamber, main oil pocket is the I shape oil pocket that three row parallel connections have more oilhole, two auxiliary oil pockets symmetrical with main oil pocket two arrange the isosceles trapezoid oil pocket having more oilhole in parallel, and repairing chamber is the rectangle oil pocket of the two oil outlet of single-row series connection; Bearing support has many horizontal oil input channels and vertical oil input channel, often list oilhole and be communicated with vertical oil input channel by horizontal oil input channel.
Beneficial effect of the present invention:
Bearing support aligning performance is good, the bearing support ratio of strength to weight is large, the structural type of oil pocket is beneficial to the oil film pressure distribution of formation circumferentially in half straight profound curve, has more oilhole and boundling oil duct form is beneficial to the oil film forming pressure uniform vertically, and the bearing capacity of bearing support is large.
