Description
Technical field
The utility model relates to a kind of rotation platform, relates in particular to a kind of large-scale rotary flat chassis of even especially big thrust.
Background technology
Thermospray refers to a series of processes, in these processes, trickle and the metal or the nonmetallic coated material that disperse, with a kind of fusing or semi-molten state, deposit to a kind of matrix surface through preparation, forms certain spray deposited layer.It is to utilize certain thermal source (as electric arc, plasma spraying or combustion flame etc.) that Powdered or thread metal or non-metallic material are heated to melting or semi-melting state, then by high-speed and high-temperature flame flow or with high pressure-temperature rare gas element flank speed, be ejected into pretreated matrix surface, embed and deposition and a kind of technology of the top coat with various functions of forming.
Large-scale rotary flat chassis is used to the super-huge rotary wheel of water turbine of thermospray, especially big thrust ball bearing is a kind of particular component being used on large-scale rotary flat chassis, rotary flat chassis design load-bearing is 200 tons, consider the stability of its rotation, thrust ball bearing diameter will reach 3 meters, because diameter is very large, machine-shaping difficulty, each parts of fuselage also can produce various errors in the course of processing, cause the in use local raceway of bearing to damage too early, affect work-ing life.Have by analysis several large reasons: steel ball size differs, bearing support, not in same plane, has irregular deformation after load-bearing, and several times rectification still exists problems.
Utility model content
The technical problems to be solved in the utility model is: the reason existing in order to solve above-mentioned analysis, the utility model provides a kind of large-scale rotary flat chassis of even especially big thrust.
The utility model solves the technical scheme that its technical problem adopts: a kind of large-scale rotary flat chassis of even especially big thrust, comprise vehicle frame, round table surface, thrust ball bearing, described vehicle frame center is provided with locating shaft, round table surface is sleeved on locating shaft, described thrust ball bearing is arranged on vehicle frame, between vehicle frame and round table surface, locating shaft and the concentric swivel arrangement that forms round table surface that arranges of thrust ball bearing, described thrust ball bearing is drawn together respectively and vehicle frame upper surface, the top chock that round table surface bottom surface is fixedly connected with and step, moving-coil, surely enclose and be arranged on the steel ball between moving-coil and fixed circle, described moving-coil is arranged on top chock, fixed circle is arranged on step, between described moving-coil and top chock and between fixed circle and step, be provided with buffering spacer.
For as required, expand round table surface, described round table surface outer ring is also detachably provided with a plurality of uniform expanding table tops.
Further, concrete, described locating shaft is connected with drive unit.
For the ease of movable rotary platform car, described bottom of frame is also provided with wheel, and driving mechanism is all installed on each wheel.
Further, particularly, ringwise, thickness is 4～6mm to buffering spacer.
The beneficial effects of the utility model are, the large-scale rotary flat chassis of even especially big thrust of the present utility model, by setting up buffering spacer, make the region that localised load is large can alleviate load, reach the object of even load, brought up to more than 1 year work-ing life by original thirties days, greatly enhances productivity, and reduces repair cost.
