Description
Technical field
The present invention relates to the composite structure of a kind of automobile air conditioner compressor magnetic clutch and compressor rotation shaft.
Background technique
The composite structure of existing a kind of automobile air conditioner compressor magnetic clutch and compressor rotation shaft is: bearing support is loaded on the compressor rotation shaft, belt pulley is contained on the bearing support, coil is housed in belt pulley, one end of compressor rotation shaft is equipped with by the fixing armature component relative with the belt pulley end face of tightening nut, armature component is made of axle coupling, friction plate and the elastic element that is connected between the two, on compressor rotation shaft, be equipped with the axle coupling against pad.Space in this composite structure between the friction plate of magnetic clutch and belt pulley end face is by adjusting the control of pad and tightening nut.Its working principle is: in the system requirements compressor operating; coil gets electric generation magnetic force; magnetic force overcomes the elastic force that elastic element produced that is connected between a coupling and friction plate and friction plate is pull-in on the end face of belt pulley; under the effect of frictional force; the belt pulley of rotation drives friction plate and rotates; friction plate drives compressor rotation shaft by the axle coupling and rotates; thereby realize the input of power; when the system requirements compressor shutdown; make coil losing electricity; under the effect of elastic element restoring force, friction plate separates with the end face of belt pulley, the compressor rotation shaft stall.
The shortcoming that the composite structure of above-mentioned automobile air conditioner compressor magnetic clutch and compressor rotation shaft exists is: elastic element and friction plate, the connection of axle coupling is by using rivet, because the error of riveting process is bigger, accurate in order to guarantee the space between friction plate and belt pulley end face, when clutch and compressor rotation shaft assembling, to add on the compressor rotation shaft that the pad more than a slice adjusts, simultaneously in order to guarantee that friction plate and belt pulley end face do not produce local the contact when not working, machining accuracy to friction plate and axle coupling, assembly precision also proposes higher requirement, and assembling back friction plate must be controlled in the definite accuracy the corresponding processing cost that increased of the raising of precision with the perpendicularity in axle coupling axle center.
Summary of the invention
The object of the present invention is to provide and a kind ofly make that the element requirement on machining accuracy is low, packaging technology is succinct, the automobile air conditioner compressor magnetic clutch of reliable performance and the composite structure of compressor rotation shaft.
For achieving the above object, the present invention adopts following scheme: the composite structure of automobile air conditioner compressor magnetic clutch and compressor rotation shaft, bearing support is loaded on the compressor rotation shaft, belt pulley is contained on the bearing support, coil is housed in belt pulley, and an end of compressor rotation shaft is connected with the armature component relative with the belt pulley end face, and armature component is the friction disk of single one, on the axle journal that compressor rotation shaft is stretched, elastic shaft sleeve is housed, the shaft shoulder of elastic shaft sleeve and compressor rotation shaft and friction disk against.
By such scheme as seen, in the composite structure of automobile air conditioner compressor magnetic clutch provided by the invention and compressor rotation shaft, because armature component is the friction disk of single one, just there is not the assembly precision problem in itself, requirement to its machining accuracy just greatly reduces like this, by machining to friction disk, can guarantee the precision of friction disk easily, setting by elastic shaft sleeve again, can guarantee more accurate space between friction disk and belt pulley end face easily, and can reduce assembling and measure this one technology.In addition, armature component is a body component, also simplifies the structure greatly, has saved fabricating cost.
The present invention is simple and reasonable for structure, and is easy to assembly, reliable performance.
Description of drawings
Accompanying drawing is the structural representation of one embodiment of the invention.
Embodiment
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
Referring to accompanying drawing
The composite structure of automobile air conditioner compressor magnetic clutch provided by the invention and compressor rotation shaft includes compressor rotation shaft 2 and automobile air conditioner compressor magnetic clutch.The automobile air conditioner compressor magnetic clutch includes bearing support 3, belt pulley 5, coil 4, armature component, and armature component is the friction disk 1 of single one.In the automobile air conditioner compressor magnetic clutch, except that armature component, the structure of other all parts is identical with existing product.Bearing support 3 is loaded on the compressor rotation shaft 2, belt pulley 5 is contained on the bearing support 3, coil 4 is contained in the belt pulley 5, friction disk 1 connects with an end of compressor rotation shaft 2 and is relative with the end face of belt pulley 5, compressor rotation shaft 2 stretches out on friction disk 1 axle head outward nut 7 is housed, elastic shaft sleeve 6 is housed on the axle journal of compressor rotation shaft 2, the shaft shoulder of elastic shaft sleeve 6 and compressor rotation shaft 2 and friction disk 1 against.Friction disk 1 has boss 1a towards the middle part of an end of belt pulley 5, elastic shaft sleeve 6 and boss 1a against.In the present embodiment, the material of elastic shaft sleeve 6 is a rubber.In addition, elastic shaft sleeve also can adopt spring.Be resisted against by elastic shaft sleeve 6 between the shaft shoulder and friction disk 1 of compressor rotation shaft 2, form the space between the end face of assurance friction disk 1 and belt pulley 5, the axial dimension of control elastic shaft sleeve 6, i.e. space between may command friction disk and belt pulley end face.
By accompanying drawing as seen, in the system requirements compressor operating, make coil 4 get electric generation magnetic force, the elastic force that magnetic force overcomes elastic shaft sleeve 6 is pull-in on friction disk 1 on the end face of belt pulley 5, under the effect of frictional force, the belt pulley 5 of rotation drives friction disk 1 and rotates, and friction disk 1 drives compressor rotation shaft 2 and rotates, and can realize the input of power; When the system requirements compressor shutdown, make coil 4 dead electricity, under the effect of elastic shaft sleeve 6 restoring forces, friction disk 1 separates with the end face of belt pulley 5, compressor rotation shaft 2 stalls.
