Abstract
The invention discloses a composite material static pressure sliding bearing with a sealing structure, comprising a bearing pad substrate (1) and a bearing pad (2). A pad surface of the bearing pad (2) is provided with a static pressure oil cavity (3), the static pressure oil cavity (3) is communicated with a high-pressure oil channel (4) passing through the bearing pad (2) and the bearing pad substrate (1), the bearing pad (2) is an elastic metal plastic pad, and a protective sleeve (5) fixedly which is fixedly connected with the bearing pad substrate (1) and used for sealing the elastic metal plastic pad (2) is arranged in the high-pressure oil channel (4). The composite material static pressure sliding bearing can effectively prevent high-pressure oil from permeating into a clearance between a resin surface layer of the elastic metal plastic pad and a metal wire transitional layer and avoid the damage of the composite material structure of the pad surface due to the high pressure oil, therefore, the elastic metal plastic pad can be applied to the static pressure bearings of heavy-load machinery apparatuses to sufficiently fulfill the properties of high bearing capacity, high abrasion without scraping the bearing pad and self-lubrication of the elastic metal plastic pad.
Description
Technical field:
The present invention relates to a kind of composite material static pressure sliding bearing, especially a kind of composite material static pressure sliding bearing with sealing configuration that can substitute existing bearing shell by elastic metal plastic tile.
Background technique:
At present, elastic metal plastic tile is because of it high bearing capacity that possesses, high abrasion, without the scraping bearing shell with have certain many characteristics such as self lubricity and replaced babbit-lined metal, is applied to important events such as water turbine, Vertical Mill gear-box and large-scale speed reducer and obtains users certainly.But the structure of existing heavy loading machinery equipment hydrostatic bearing has but limited the application of elastic metal plastic tile.
Existing heavy loading machinery equipment hydrostatic bearing all has the bearing shell matrix and is fixed in bearing shell on the bearing shell matrix, on the tiling (pressure-bearing surface) of bearing shell, be provided with the static pressure oil pocket, the static pressure oil pocket communicates with the high-pressure oil duct that passes bearing shell and bearing shell matrix, high pressure oil feeds lubricant oil by high-pressure oil duct in the static pressure oil pocket, to form the pressure-bearing oil film.Because elastic metal plastic tile is a kind of composite structure, have small space between its resin surface layer and the wire transition layer, though do not influence adhesive strength, but then will cause certain influence to adhesive strength if apply extreme pressure lubricant (being generally about 25MPa) at its section part, therefore the structural failure that will cause the tiling composite material when serious also is being to use the babbit-lined metal that falls behind than the bearing shell in the high specific pressure hydrostatic bearing framework.
Summary of the invention:
The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, a kind of composite material static pressure sliding bearing with sealing configuration that can be substituted existing bearing shell by elastic metal plastic tile to be provided.
Technical solution of the present invention is: a kind of composite material static pressure sliding bearing with sealing configuration, bearing shell matrix 1 and bearing shell 2 are arranged, on the tiling of bearing shell 2, be provided with static pressure oil pocket 3, static pressure oil pocket 3 communicates with the high-pressure oil duct 4 that passes bearing shell 2 and bearing shell matrix 1, described bearing shell 2 is elastic metal plastic tiles, is provided with to fixedly connected the sheath 5 that is used to seal elastic metal plastic tile 2 sections with bearing shell matrix 1 in described high-pressure oil duct 4.
Described sheath 5 is cylindric, is equipped with screw thread on the interior outer cylinder.
The outside, the upper end of described sheath 5 is the conical surface, and the described conical surface matches with taper hole on being positioned at elastic metal plastic tile 2.
Many projection endless belts 6 are arranged on the described conical surface.
There is the gap of 0.5～1.5mm the upper-end surface of described sheath 5 and static pressure oil pocket 3 bottom surfaces.
The present invention can prevent effectively that high pressure oil from infiltrating space between the resin surface layer of elastic metal plastic bearing and the wire transition layer, avoid the damage of high pressure oil to the tiling composite structure, therefore elastic metal plastic tile can be applied to the heavy loading machinery equipment hydrostatic bearing, give full play to high bearing capacity that elastic metal plastic bearing has, high wear resistance, without scraping bearing shell and self-lubricating property.Especially at the inside and outside cylinder of sheath processing fine thread, seal in the time of can realizing with the sealing of bearing shell matrix and withstand voltage experiment; With the outside, the upper end of sheath be designed to the conical surface and be positioned at elastic metal plastic tile on taper hole match and on the described conical surface many projection endless belts of processing, but equal enhanced leaktightness effects guarantees that the high pressure oil in the static pressure oil pocket does not leak.The gap of 0.5 set～1.5mm is the appropriate clearance that guarantees between sheath and the friction pair part in the upper-end surface of sheath and static pressure oil pocket bottom surface.

Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the Z portion enlarged view of Fig. 1.
Embodiment:
Below in conjunction with description of drawings the specific embodiment of the present invention.As shown in Figure 1, 2, 3: a kind of composite material static pressure sliding bearing with sealing configuration, have with prior art identical bearing shell matrix 1 and bearing shell 2, on the tiling of bearing shell 2, be provided with static pressure oil pocket 3, static pressure oil pocket 3 communicates with the high-pressure oil duct 4 that passes bearing shell 2 and bearing shell matrix 1, different is that used bearing shell 2 is elastic metal plastic tiles with prior art, is provided with to fixedly connected the sheath 5 that is used to seal elastic metal plastic tile 2 sections with bearing shell matrix 1 in described high-pressure oil duct 4.Sheath 5 the most handy Cuprum alloys also can select for use other metals or non-metal alloy material to make according to performance requirement, and shape can be cylindric, all processes fine thread on interior outer cylinder, for the bearing shell matrix be tightly connected and withstand voltage experiment time sealing is used.The outside, upper end of sheath 5 is processed as the conical surface, processes taper hole on elastic metal plastic tile 2, the taper hole on the sheath 5 matches with the conical surface.Many projection endless belts 6 of processing on the described conical surface, to increase sealing effect, preferably there is the gap of 0.5～1.5mm the upper-end surface of sheath 5 and static pressure oil pocket 3 bottom surfaces.
When high pressure oil fed lubricant oil by high-pressure oil duct in the static pressure oil pocket, high pressure oil flow through from jacket surface, can prevent effectively that high pressure oil from infiltrating space between the resin surface layer of elastic metal plastic bearing and the wire transition layer.
