Describe the bearing according to the compressor 1000 of the embodiment of the present invention below with reference to Fig. 1-Fig. 4, bearing can be used in compressor 1000.
As Figure 1-Figure 4, according to the bearing of the compressor 1000 of the embodiment of the present invention, can comprise flange part and collar, collar is located at the side (such as, downside) as shown in figs. 2 and 4 of flange part and is connected with flange part.Bearing has center hole, center hole through-shaft neck and flange part.
At least one in flange part and collar is spinning part, and that is, flange part to be spinning part or collar be spinning part or flange part and collar are spinning part simultaneously.
Specifically, spinning part is made by spinning process.Spinning process is by rotational workpieces, makes the force bearing point of workpiece by putting line, then by line to face, gives certain pressure simultaneously make metallic material form the technique of a certain shape along this Direction distortion and flowing at certain direction hobboing cutter.The major advantage of spinning process comprises: 1) local continuous processing, and deformation force is little; 2) spinning precision is high, and tolerance of size reaches IT8, and roughness reaches 3.2, and the intensity of workpiece and hardness improve; 3) stock utilization is high, and die cost is low, only has 1/5th of common punch die, is applicable to batch production, good economy performance.
Alternatively, for spinning part such as collar and flange part by spinning process machine shaping, can heat-treat (quenching or annealing), be conducive to the intensity and the hardness that improve spinning part further.
Thus, by making at least one in flange part and collar for spinning part, be conducive to the weight of reduction bearing blank (in certain embodiments, be conducive to reducing more than 25% of blank weight), reduce the processing cost of bearing, thus be conducive to the price reducing bearing, and by the spinning part that spinning process is made, there is high dimensional accuracy, high strength, high hardness, high rigidity and high Young's modulus, thus be conducive to the dimensional accuracy of the entirety improving bearing, intensity, hardness, rigidity and Young's modulus, and on the basis ensureing bearing integral intensity and hardness, the wall thickness of spinning part can also be reduced, to reduce the size of bearing, when bearing is used in compressor 1000, be conducive to the miniaturization realizing compressor 1000.
According to the bearing of the compressor 1000 of the embodiment of the present invention, by making at least one in flange part and collar for spinning part, be conducive to the weight reducing bearing blank, reduce the processing cost of bearing, thus be conducive to the price reducing bearing, and by the spinning part that spinning process is made, there is high dimensional accuracy, high strength, high hardness, high rigidity and high Young's modulus, thus be conducive to the dimensional accuracy of the entirety improving bearing, intensity, hardness, rigidity and Young's modulus, and on the basis ensureing bearing integral intensity and hardness, the wall thickness of spinning part can also be reduced, to reduce the size of bearing, when bearing is used in compressor 1000, be conducive to the miniaturization realizing compressor 1000.
