Abstract
The utility model discloses a compressor crank shaft rotating device which comprises a machine body, a crank shaft and a planar bearing, wherein a shaft sleeve hole is formed in the machine body; the crank shaft comprises an upper shaft and a lower shaft; the upper shaft is connected with the lower shaft through a stopping block; a bearing fixing slot is formed on the machine device and positioned on the outer ring of the shaft sleeve hole; the planar bearing is positioned in the bearing fixing slot; the lower shaft passes through the shaft sleeve hole; and the lower surface of the stopping block is contacted with the planar bearing. According to the compressor crank shaft rotating device, the planar bearing rotates along with the crank shaft, so that a compressor does not produce much noise due to mutual friction among metal planes; and therefore, during rotation, the friction resistance is low, the working noise is low, and the working efficiency is high.
Description
Technical field
The utility model relates to a kind of compressor assembly, specifically is a kind of compressor crank shaft slewing gear.
Background technique
Compressor crank shaft slewing gear in the past comprises body and bent axle, and said body is provided with axle sleeve hole.
Said bent axle comprises axle and lower shaft, and said going up between axle and the lower shaft connects through block.
Said lower shaft passes axle sleeve hole, and the lower surface of said block contacts with body.
Said lower shaft links to each other with compressor rotor, and the said axle of going up links to each other with piston, and the driven by motor bent axle rotates, and then drives piston motion by bent axle.Performance when therefore bent axle rotates has very big influence to the service behaviour of compressor.
Two metal flats that the block of said bent axle contacted with body when bent axle rotated can produce friction, and the performance when bent axle rotates is restricted by the degree of finish of these two metal flats.And described two metal flats are machining; Degree of finish promotes limited; Can't obviously reduce friction and resistance; Send than big noise because of the friction between two metal flats when causing bent axle to rotate, and influence compressor operating efficient, cause the raising of the total quality of compressor to receive restriction.
The model utility content
The utility model technical problem to be solved is the defective that overcomes existing technology, and surface friction drag was little when a kind of the rotation was provided, operating noise is low, the compressor crank shaft slewing gear of high working efficiency.
For solving the problems of the technologies described above, the compressor crank shaft slewing gear of the utility model, it comprises body and bent axle, said body is provided with axle sleeve hole.
Said bent axle comprises axle and lower shaft, and said going up between axle and the lower shaft connects through block.
Said compressor crank shaft slewing gear also comprises plane bearing, and said body is provided with the bearing fixing groove, and said bearing fixing groove is located at the outer ring of axle sleeve hole, and said plane bearing is positioned at the bearing fixing groove.
Said lower shaft passes axle sleeve hole, and the lower surface of said block contacts with plane bearing.
In the compressor crank shaft slewing gear of the utility model; When said bent axle rotates; The lower surface of said block not can with the metal flat direct friction of body, but the plane bearing below the block rotates with bent axle, and is good lubricated through guaranteeing that to oiling of bent axle plane bearing has when rotating; Thereby can significantly reduce surface friction drag; Make compressor can not produce very big noise, improved the working efficiency of compressor simultaneously, and then improved the complete machine quality of compressor because of the phase mutual friction between the metal flat.
Therefore, the compressor crank shaft slewing gear of the utility model compared with prior art, has that surface friction drag is little, operating noise is low, the advantage of high working efficiency.
As preferably, said plane bearing comprises plane, lower plane, ball and retainer, and the said material that goes up plane and lower plane is 65Mn.
As preferably, the material of said ball is 65Mn.
As preferably, said retainer is the high-temperature resistance plastice retainer.
As above-mentioned preferred further preferred, said retainer is the teflon retainer.

Shown in the figure: 1, body, 2, bent axle, 3, axle sleeve hole, 4, go up axle, 5, lower shaft, 6, block, 7, plane bearing, 8, the bearing fixing groove, 9, go up the plane, 10, lower plane, 11, ball, 12, retainer.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation; But the utility model is not limited to following examples; The technician of same area can propose other embodiment in the technological scheme framework of the utility model, but these embodiments include in the protection domain of the utility model.
As shown in the figure, the compressor crank shaft slewing gear of the utility model, it comprises body 1 and bent axle 2, said body 1 is provided with axle sleeve hole 3.
Said bent axle 2 comprises axle 4 and lower shaft 5, and said going up between axle 4 and the lower shaft 5 connects through block 6.
Said compressor crank shaft slewing gear also comprises plane bearing 7, and said body 1 is provided with bearing fixing groove 8, and said bearing fixing groove 8 is located at the outer ring of axle sleeve hole 3, and said plane bearing 7 is positioned at bearing fixing groove 8.
Said lower shaft 5 passes axle sleeve hole 3, and the lower surface of said block 6 contacts with plane bearing 7.
As preferably, said plane bearing 7 comprises plane 9, lower plane 10, ball 11 and retainer 12, and the said material that goes up plane 9 and lower plane 10 is 65Mn.
As preferably, the material of said ball 11 is 65Mn.
As preferably, said retainer 12 is the high-temperature resistance plastice retainer.
As above-mentioned preferred further preferred, said retainer 12 is the teflon retainer.
In the compressor crank shaft slewing gear of the utility model; When said bent axle 2 rotates, the lower surface of said block 6 not can with the metal flat direct friction of body 1, but the plane bearings 7 below the block 6 rotate with bent axle 2; Through guaranteeing that to oiling of bent axle 2 plane bearing 7 has good lubricating when rotating; Thereby can significantly reduce surface friction drag, and make compressor can not produce very big noise because of the phase mutual friction between the metal flat, improved the working efficiency of compressor simultaneously.
Therefore, the compressor crank shaft slewing gear of the utility model compared with prior art, has that surface friction drag is little, operating noise is low, the advantage of high working efficiency, makes compressor complete machine quality be significantly improved.
