Abstract
The invention discloses a bearing body of a hollow axial hydrostatic bearing. The bearing body is provided with two single lugs, an oil cavity, a ribbed slab, an axial lightening hole and a lightening hole, wherein the lightening hole is vertical to the axial lightening hole, the oil cavity comprises a main oil cavity, two auxiliary oil cavities, an oil supplementing cavity, two coherent oil channels with variable cross-sections, a plurality of oil outlets, a plurality of horizontal oil inlet passages and a plurality of vertical oil inlet passages, 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 oil outlets in each column are communicated with the vertical oil inlet passages through the horizontal oil inlet passages, and the bearing body is hinged with a bearing seat. The bearing body disclosed by the invention is good in aligning performance and large in ratio of strength to weight, the form of the oil cavity is beneficial for formation of oil film pressure distribution in a semi-circle sine curve along the peripheral direction, the form of the plurality of 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 hydrostatic bearing bearing support, particularly a kind of bearing support 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 bearing support aligning performance, bearing support strength and stiffness and upper oil cavitie structural type thereof are most important.
Summary of the invention
The object of this invention is to provide the bearing support of hollow shaft type hydrostatic bearing.
The bearing support of the present invention is provided with two monaural rings, oil pocket, axial lightening hole and lightening hole, lightening hole is vertical with axial lightening hole, oil pocket is made up of a main oil pocket, two auxiliary oil pockets, repairing chamber, two variable cross section boundling oil ducts, multiple oil outlet, gusset, many horizontal oil input channel oil input channels vertical with many, main oil pocket is the I shape oil pocket of three row multiple oil outlet in parallel, two auxiliary oil pockets are symmetrical with the main oil pocket two isosceles trapezoid oil pockets arranging multiple oil outlet in parallel, and repairing chamber is the rectangle oil pocket of single-row series connection two oil outlets; Often list oilhole to 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.

Embodiment
Refer to Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, the bearing support 10 of the present invention is provided with two monaural rings 100, oil pocket 101, gusset 111, axial lightening hole 109 and lightening hole 110, lightening hole 110 is vertical with axial lightening hole 109, oil pocket 101 is by a main oil pocket 102, two auxiliary oil pockets 103, a repairing chamber 104, article two, variable cross section boundling oil duct 105, multiple oil outlet 106, many horizontal oil input channel 107 oil input channel 108 vertical with many is formed, main oil pocket 102 is I shape oil pockets of three row multiple oil outlet 106 in parallel, two auxiliary oil pockets 103 are symmetrical with main oil pocket 102 two isosceles trapezoid oil pockets arranging multiple oil outlet 106 in parallel, repairing chamber 104 is rectangle oil pockets of single-row series connection two oil outlets 106, often list oilhole 106 to be communicated with vertical oil input channel 108 by horizontal oil input channel 107.
Working procedure of the present invention is: when pebble mill is fully loaded with static, width due to main oil pocket 102 is less than neck of hollow shaft and bearing support contact resilient deformed width, by the three row oil circuit in parallel with back pressure function, form main oil pocket 102 enclosed space, the weight of the hydraulic oil that its internal pressure raises and bearing body structure shared solid of rotation and mixture, pebble mill starting with full load and when normally working, the high pressure 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 bearing support, solid of rotation is floated, form complete lubricant film, when neck of hollow shaft rotates, neck of hollow shaft rotates and the hydraulic oil be adsorbed on its external cylindrical surface is moved thereupon, the lubricant film that neck of hollow shaft screws in side between inner cylindrical surface on bearing support is thinning, even occur that lubricant 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 lubricant film is complete, realize fully liquid lubrication, bearing support 10 and bearing support chain connection, aligning performance is good.
