Abstract
The utility model belongs to the technical field of novel piston type automobile air-conditioning compressors, in particular to a front cover of the novel piston type automobile air-conditioning compressor. The front cover is characterized by being in a circular structure; a stepped cylinder and a circular opening for leading out a main shaft are arranged at the front part of the stepped cylinder; front cover screw holes are arranged on the periphery of a circular sealing end surface at the rear part of the front cover; the front cover is in an arc transitional curved surface from bottom to top; reinforcing ribs are uniformly arranged on the surface of the curved surface; the bottom of each reinforcing rib is connected with the sealing end surface of the front cover; the top of the front cover is in an annular structure and is fixed on the periphery of the circular opening for enhancing the strength of the front cover. Compared with the prior art, the front cover has the advantages of simple structure and strong generality; and in addition, the work procedures for installing are reduced, the production cost is greatly reduced and the production efficiency is improved.
Description
[technical field]
The utility model belongs to the piston-type automobile air-conditioning compressor technical field, specifically a kind of novel piston formula automobile air conditioner compressor protecgulum.
[background technique]
The automobile air conditioner compressor protecgulum is one of part commonly used in the automobile air conditioner compressor, its effect: the one, play the effect of compressor seal, the 2nd, for pulley provides supporting, the 3rd, by axle envelope and felt collar main shaft is drawn from compressor inside, most in the market compressor protecgulum is equipped with the ring washer groove, coil loop is fixed to protecgulum by the ring washer groove, not only increased the operation when installing, and increased the cost of part, so a kind of novel automobile air conditioner compressor protecgulum need be provided.
[summary of the invention]
The utility model provides a kind of novel piston formula automobile air conditioner compressor protecgulum in order to overcome the deficiencies in the prior art.
To achieve these goals, the utility model has designed a kind of novel piston formula automobile air conditioner compressor protecgulum, and it is characterized in that: protecgulum is a round structure, and the front portion is for the ladder cylinder and be provided with the circular open that is used to draw main shaft; Around the circular seal end face of preceding postoperculum, be provided with the protecgulum screw hole; Protecgulum is the excessive curved surface of arc from bottom to up, and evenly is provided with stiffening rib at curved surface, and every stiffening rib bottom connects the protecgulum seal face, the top adopt loop configuration be fixed on circular open around.Be used to increase protecgulum intensity.
The utility model is compared with prior art, not only simple in structure, highly versatile, and reduced operation when installing, and significantly reduced cost of production, improved manufacturing efficiency.
[description of drawings]
Fig. 1 is the utility model structural representation.
Fig. 2 is the side view of Fig. 1.
Referring to Fig. 1 and Fig. 2,1 is protecgulum; 2 is the circular seal end face; 3 is stiffening rib; 4 is circular open; 5 is screw hole, and 6 is the ladder cylinder.
[embodiment]
Below in conjunction with accompanying drawing the utility model is described further.
As depicted in figs. 1 and 2, protecgulum 1 of the present utility model is a round structure, and is anterior for ladder cylinder 6 and be provided with circular open 4 and be used to draw main shaft; Around the circular seal end face 2 at protecgulum 1 rear portion, be provided with screw hole 5; Protecgulum 1 is the excessive curved surface of arc from bottom to up, and evenly is provided with stiffening rib 3 at curved surface, every stiffening rib 3 protecgulum seal faces 2, and stiffening rib 3 tops adopt loop configuration to be fixed on around the circular open 4 at protecgulum 1 top, are used to increase protecgulum intensity.Cancellation ring washer groove need not to install ring washer when coil loop is installed in the ladder cylinder 6 of protecgulum front portion, and protecgulum and coil loop are fastening by interference fit.Adopt the protecgulum of this design not only simple in structure, highly versatile, and reduced operation when installing, and significantly reduced cost of production, improved manufacturing efficiency.
