Description
Technical field
The utility model relates to the electrodynamic vibration generator in the environmental mechanics testing installation, is specifically related to the hydrostatic bearing of electrodynamic vibration generator horizontal sliding table, and this hydrostatic bearing is used for the supporting and the guiding of vibrating table horizontal sliding table.
Background technique
Horizontal sliding table provides the slip stage body of substantially horizontal vibration test.On the supporting structure of electrodynamic vibration generator horizontal sliding table, general " V " guide rail (Fig. 1) and the open oil pressure hydrostatic slideway modes such as (Fig. 2) of adopting.Its basic structure is: be equipped with certain thickness stone material in the bottom of slide unit flat board, as basic supporting mass.Between this supporting mass and slide unit flat board, injection pressure oil makes it to form the thick oil film of one deck 0.1mm～0.2mm.Rely on this oil film to bear the weight of test specimen and lubricate between stone material and slide unit flat board.In the work, electrodynamic vibration generator drives the slide unit flat board and slidably reciprocates along the guide rail direction, makes test specimen produce the substantially horizontal vibration.Adopt the horizontal sliding table of " V " guide rail, main feature is: simple in structure, easy processing, but a little less than the ability of antidumping moment.This guide rail is mainly used in the horizontal vibration test of carrying out centre of gravity, little quality test specimen.Adopt the horizontal sliding table of open oil pressure hydrostatic slideway, relatively difficulty is processed in having relatively high expectations of its guide rail.Slide unit flat board and supporting mass are still continued to use down the main structure of " V " guide rail slide unit, are about to stone material as main supporting mass, still need oil film as load-bearing and the main carrier that lubricates between stone material and slide unit flat board.But because working pressure oil is to give the hydrostatic slideway fuel feeding by slide unit is dull and stereotyped, and working pressure is bigger, after work a period of time, raises owing to oily temperature rise has more significantly the temperature of slide unit flat board.Though the ability of the antidumping moment of the guide rail of this kind structure increases, ability of its carrying test specimen quality then depends on the bearing capacity of stone material below the slide unit flat board.
With the exception of this, also have a kind of hydrostatic bearing, form by " V " type slide block and two kinds of textural associations of T-shape slide block." V " type slide block is responsible for " guiding ", and the T-shape slide block is responsible for load-bearing (Fig. 3).These two kinds of Structures under Hydrostatic Pressure bearing pack are used altogether, the bearing capacity and the antidumping moment of the slide unit of can improving the standard greatly, and can cancel the stone material that the dull and stereotyped bottom of slide unit is used to support.Because pressure oil does not pass through the slide unit flat board when work, so the slide unit flat board can not heat up because of the operating time is long.But the shortcoming of this combined type hydrostatic bearing is the structure more complicated.
Summary of the invention
The utility model provides a kind of novel four sides oil film static pressure bearing that is used for the electrodynamic vibration generator horizontal sliding table, its objective is to design a kind of simple in structure, and both had big bearing capacity and an antidumping moment capacity, the hydrostatic bearing that has higher guiding accuracy again is to solve the contradiction between existing hydrostatic bearing structure and the performance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of novel four sides oil film static pressure bearing, comprise bearing support and be located at slide block in the bearing support, its innovation is: the sliding body cross section of described slide block is a rectangle, this sliding body has four the slip working surfaces in upper and lower, left and right, these four slip working surfaces all with the respective side Spielpassung of bearing support, wherein, two the slip working surfaces in up and down are in substantially horizontal and are parallel to each other, and a left side is in Vertical direction with right two slip working surfaces and is parallel to each other; Four slip working surfaces in upper and lower, left and right of the corresponding sliding body of the respective side of bearing support are respectively equipped with high-voltage oil cavity, and each high-voltage oil cavity is interconnected.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described bearing support is made up of bearing base, bearing cap and two side position limit sockets, the sliding body of slide block is positioned at the space of bearing base, bearing cap and two side position limit socket restrictions, upper and lower two slip working surfaces of sliding body respectively with the bottom surface of bearing cap and the end face Spielpassung of bearing base, left and right two slip working surfaces of sliding body cooperate with the side clearance of two side position limit sockets respectively.
2, in the such scheme, described slide block also is provided with attachment post, and this attachment post one end is fixedlyed connected with sliding body, and the other end stretches out from bearing support and is used to connect the slide unit flat board.
3, in the such scheme, the high-voltage oil cavity area of hydrostatic bearing can be configured according to its load bearing requirements, makes that the slide block in the bearing can keep level and smooth motion under the load that requires.
4, in the such scheme, the pressure oil working pressure of hydrostatic bearing is generally 1Mpa～20Mpa.
The utility model design principle is: be provided with the slide block that an energy moves around along a direction in the centre of hydrostatic bearing.Four slip working surfaces in upper and lower, left and right at this slide block are provided with the high-voltage oil cavity that limits its motion respectively.The last lower oil cavitie of slide block is for the weight of bearing test specimen and big antidumping moment is provided; Oil pocket about slide block is not depart from for this slide block can keep its moving direction when moving.By said structure, this programme will have " V " type slide block now and two kinds of hydrostatic bearings of T-shape slide block unite two into one, and can reach big load-bearing, big antidumping moment, can play the function that keeps moving direction again, has simplified mechanical structure simultaneously.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the utility model had both had big bearing capacity and antidumping moment capacity, had higher guiding accuracy again, was applicable to the horizontal vibration test of the test specimen of high center of gravity, big quality.
2, the utility model is simple in structure, and is economical and practical, can dispose the quantity of hydrostatic bearing according to the weight of the size of slide unit and test specimen, satisfies different clients' test requirements document.
3, the utility model can also can be used in combination this hydrostatic bearing according to different load bearing requirements, makes the bearing capacity of horizontal sliding table reach 10 tons, antidumping moment and reaches more than the 300kNm.
4, the utility model does not re-use the supporting mass of stone material as load, and because pressure oil is no longer dull and stereotyped inner by slide unit when work, after the pilot system work long period, the slide unit flat board can keep room temperature and not raise.
