Description
Technical field
The utility model relates to a kind of compressor, especially a kind of reciprocating piston type totally-enclosedmotor-compressor that can be used in family expenses and the small refrigeration systems.
Background technique
Existing reciprocating piston type totally-enclosedmotor-compressor is loaded in the casing of a sealing; It comprises component such as rotor, motor stator, air suction silencer, cylinder head, valve group parts, piston, wrist pin, connecting rod, bent axle, frame, cover, casing; Have in the crankshaft hole that faceted bent axle is loaded on frame; Bent axle facet and frame axis hole supporting surface are in contact with one another; Play spacing supporting effect up and down, bent axle facet and frame axis hole supporting surface are regulated the resistance excessively that axial float causes with suitable axial clearance.During compressor operating, the motor drives crankshaft rotating, the rotation of bent axle makes connecting rod drive piston carry out suction and discharge work.Bent axle facet and rack support face have certain clearance and behavior tolerance; Bent axle motion relative under the drive of motor with frame; Because the deadweight of parts such as rotor, bent axle adds the pressure that is caused by suction and discharge work, make two interplanars produce frictional loss.The facet of bent axle and the supporting surface of frame are the slip surface frictions, and during compressor operating, the further minimizing of the sliding friction loss that produces herein can receive the restriction of crankshaft strength, machining accuracy and the lubricated limit.Simultaneously because the support of the supporting surface of the facet of bent axle and frame belongs to the hard support that is connected; When compressor start and high speed rotating; Have certain play up and down between bent axle plane and rack support face, yet two interplanars there is not any buffer capacity, cause the increase of noise.For reducing frictional loss and mechanicalness noise here; Adopt small axle diameter, facet in the existing technology or adopted roll extrusion and grinding process; Reduce friction loss and the level of mechanicalness noise to reduce active line speed, friction area and the roughness of friction pair here, to reach.But because the machining accuracy and the control of the related components of compressor have very high requirement, so the implementation of above-mentioned two kinds of methods has certain limit, and to improve effect be not very outstanding.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing technology, the utility model provides a kind of can effectively reduce mechanical loss and mechanicalness noise, significantly improves the reciprocating piston type Totally-enclosed-type compressor of compressor overall efficiency.
The technological scheme that the utility model solves its technical problem is:
A kind of reciprocating piston type Totally-enclosed-type compressor comprises frame, is provided with axis hole in the middle of the frame; Bent axle is installed in the axis hole, and described bent axle is provided with the bent axle plane, establishes the frame support face around the described axis hole; And bent axle plane and frame support face are oppositely arranged; Said frame support face is provided with an annular groove, and described annular groove is positioned at the axis hole outer ring, is provided with a bearing unit in the described annular groove; And described bearing unit connects bent axle plane and frame support face, and described bearing unit is followed successively by universal regulated pad, following thrust washer, plane bearing and last thrust washer from lower to upper.
As improvement, universal regulated pad, following thrust washer and plane bearing are set in the groove, described bent axle plane is provided with tool withdrawal groove, and the described thrust washer of going up is arranged in the tool withdrawal groove.
Connection through bearing unit between bent axle plane and the rack support face belongs to the support that is flexible coupling; When compressor start and high speed rotating; There is certain play up and down between bent axle plane and rack support face; Make the slip surface friction between bent axle plane and the frame support face become the rolling wire friction, two interplanars are through bearing unit free adjustment and the buffering power that disappears, and avoid connecting the increase that causes noise because of hard; Can reduce the mechanical loss here, thereby the efficient of compressor complete machine is further promoted.
Adopt the design of universal regulated pad in the structure, just can reduce the accumulation load that interior planeness of frame groove and chamfering cause, reduced mechanical loss, improved compressor operating efficient.Simultaneously frame has adopted the higher groove structure of concentricity, and by the minimum force bearing point of universal regulated pad free adjustment and cushion stressedly, can guarantee fully that bearing unit starting and play during high speed rotating, avoids the increase of compressor noise.
The beneficial effect of the utility model is: the utility model is provided with a bearing unit between bent axle plane and frame support face, converts the sliding friction between bent axle plane and the frame support face into rolling friction, greatly reduces mechanical loss and noise.
Description of drawings
Fig. 1 is the sectional structure schematic representation of the utility model.
Fig. 2 is the structural representation of bearing unit.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Like Fig. 1, shown in 2, a kind of reciprocating piston type Totally-enclosed-type compressor comprises frame; Be provided with axis hole 5 in the middle of the frame, bent axle 2 is installed in the axis hole 5, bent axle 2 is provided with bent axle plane 1; Establish frame support face 4 around the axis hole 5, and bent axle plane 1 is oppositely arranged with frame support face 4, the frame support face is provided with an annular groove; And annular groove is positioned at the axis hole outer ring; Be provided with a bearing unit 3 in the annular groove, bearing unit 3 connects bent axle plane 1 and frame support face 4, and bearing unit 3 is followed successively by universal regulated pad 10, following thrust washer 9, plane bearing 8 and last thrust washer 6 from lower to upper.Universal regulated pad, following thrust washer and plane bearing are set in the groove, and described bent axle plane is provided with tool withdrawal groove, and last thrust washer is arranged in the tool withdrawal groove.
Be provided with the universal regulated pad in the bearing unit, descend thrust washer, plane bearing to carry out guide-localization through the groove of frame; Can avoid compressor to occur the bump bent axle diameter of axle in the startup and the process that runs up or in the transposition joint process on the throne; Can shorten simultaneously the distance of the stressed fulcrum of bent axle, it is stressed to reduce to rub.Last thrust washer 6 through adjustment, is in the horizontal position of bent axle tool withdrawal groove thrust washer owing in running, all have relative running with frame and bent axle all the time, avoids because too small the causing with the diameter of axle in gap rubs relatively.
Connection through bearing unit 3 between bent axle plane 1 and the rack support face 5 belongs to the support that is flexible coupling; When compressor start and high speed rotating; There is certain play up and down between bent axle plane and rack support face; Make the slip surface friction between bent axle plane and the frame support face become the rolling wire friction, two interplanars are through bearing unit 3 free adjustment and the buffering power that disappears, and avoid connecting the increase that causes noise because of hard; Can reduce the mechanical loss here, thereby the efficient of compressor complete machine is further promoted.
