Be illustrated in figure 7 as the 3rd kind of structural type of existing plane thrust ball bearing, a whole set of Bearing Installation is between the supporting surface 6a of the supporting surface 1a of bent axle 1 and axle sleeve 6, a protruding 6b is arranged on the axle sleeve 6, a protruding 1b is arranged on the bent axle 1, the mounting hole of upper support sheet 2 is located with protruding 1b, the mounting hole of retainer 3 and lower support sheet 5 is located with protruding 6b, the mounting hole diameter D1 of upper support sheet 2 and the mounting hole diameter D2 of lower support sheet 5 are identical, be D1=D2, a gap h is arranged between protruding 1b and the protruding 6b.This structural type has kept the high advantage of plane thrust ball bearing efficient, and owing to the existence of bearing projection 6b, the length of axle sleeve 6 increases simultaneously, thereby improves the operation stability of compressor.Shortcoming is that the assembly process process of compressor is bad because upper support sheet 2 stuck phenomenons between protruding 1b and protruding 6b often take place during the assembling compressor in the existence of gap h.
Summary of the invention
Technical problem to be solved by this invention is to propose a kind ofly can improve compressor efficiency, guarantees compressor operating stability, can improve the plane thrust ball bearing structure of compressor Assembling Production efficient again.
For solving the problems of the technologies described above, solution of the present invention is: diameter-variable plane thrust ball bearing comprises upper support sheet, retainer and lower support sheet, the mounting hole of described lower support sheet and the mounting hole of described retainer are located with the projection of compressor axle sleeve, the mounting hole of described upper support sheet is located with compressor crank shaft, and the installation aperture of described upper support sheet is different with the installation aperture size of described lower support sheet.
Above-mentioned diameter-variable plane thrust ball bearing is provided with pad between described upper support sheet or lower support sheet and its attachment face.
Above-mentioned diameter-variable plane thrust ball bearing, the cylindrical of described upper support sheet, retainer and lower support sheet is shaped as petal-shaped.
The present invention is owing to adopted technique scheme, and it utilizes a kind of mode of structure that becomes the aperture, and make the compressor of using this plane thrust ball bearing produce following remarkable result: 1, the efficient of compressor improves more than 3%; 2, adopt the protruding structure of axle sleeve, sleeve length is longer, the stability when guaranteeing compressor operating; 3, the mounting hole of the upper support sheet of plane thrust ball bearing is located with bent axle, can avoid stuck the wait abnormality of compressor because of adopting plane thrust ball bearing to cause.
