Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Refer to shown in Fig. 1, vehicle-mounted air conditioner compressor spindle assemblies of the present invention, mainly include front end cylinder cap, pass
Dynamic main shaft, swash plate component and planetary plate component, the swash plate component include swash plate and thrust bearing, wherein：
Swash plate component includes swash plate and thrust bearing, and swash plate has 22 ° of inclined plane.
The planetary plate component includes planetary plate, piston rod and piston.Wherein, planetary plate is preferred to use the rotation of split setting
Platen and the disk shoulder of annular composition, spinning disk use the high-wear-resistant alloy such as potassium steel or Pattern Bainite Alloy steel as load mechanism
Steel is made, and disk shoulder is preferred to use aluminium alloy and is easy to machining.Spinning disk is formed by alloy mold, and structure is disc
And provided with the spinning gear teeth, the spinning gear teeth are conical tooth, frustoconical bevel angle is 22 °, and by being pressed into disk shoulder so as to form entirety.
Disk shoulder for annular shape and forms multiple ball recess by machining.The two ends of piston rod are spherical, and piston rod one end is put
In the ball recess for entering disk shoulder, and by rolling the edge formation arc groove button of ball recess so as to by one end of piston rod
Pin, while the spheric end of piston rod can be in ball recess slidably.Set, and be expert at relatively between swash plate and planetary plate
Annular steps are set on astrolabe, thrust bearing is enclosed in annular steps, space are left between swash plate and planetary plate, for moistening
Lubricating oil enters, further to providing lubrication between thrust bearing and planetary plate and load bearing seat.When swash plate is in transmission main shaft band
Make to rotate above and below planetary plate while dynamic lower rotation, and then drive piston rod so that piston does straight reciprocating motion to refrigerant
It is compressed.Roller surface bearing is set to ensure the stability of activity relatively between the two between swash plate and planetary plate.
Swash plate rotation is so as to planetary plate progress spinning so that planetary plate is with the inclined plane dipping and heaving of swash plate so that living
Plug is moved back and forth, and transmission main shaft can be likely to result in spindle eccentricity rotation by the reaction force of planetary plate axially and radially during being somebody's turn to do
Turn, so as to reduce the stability and service life of compressor operating, and increase the operation noise of compressor.Therefore, the present invention exists
