Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
In the utility model, in the case where not making opposite explanation, the noun of locality such as " upper and lower, top, bottom " used is generally
It is each part mutual alignment either on vertical, vertical or gravity direction for direction shown in the drawings
Relationship description word.
A series of problem, the utility model such as deformation is caused to be directed to one in order to solve the welding of prior art middle (center) bearing
Bearing of the kind for rotary compressor, by changing the particular location of solder joint, to reduce bearing welding deformation, improves compressor
Performance And Reliability.
As shown in figure 1, a kind of bearing for rotary compressor, including bearing main body 1, the end face of bearing main body 1 it is outer
Ring portion 11 formed with axially through and circumferentially spaced distribution multiple hollow-out parts 2, the peripheral part 12 of bearing main body 1 is provided with
Multiple solder joints 3；
Wherein, along the circumferencial direction, the axis by bearing main body 1 and with circumferential two sides of hollow-out parts 2
Edge is formed as hollow out fan section a between circumscribed two cutting sections respectively, and hollow-out parts 2 are identical with hollow out fan section a number
And correspond, the solder joint 3 set in each hollow out fan section a is not more than 1, and solder joint 3 is arranged on the footpath of corresponding hollow-out parts 2
Laterally and it is respectively positioned in corresponding hollow out fan section a.
Bearing of the present utility model for rotary compressor, due to the relative position and quantity to its solder joint and hollow-out parts
Preferred arrangement, it can effectively reduce the welding stress of bearing main body 1 so that the bearing, which is advantageous to the stress after welding operates, to be released
Put, reduce bearing deformation, therefore the bearing for rotary compressor for changing utility model has the small and welding structure of deformation more firm
The advantages that leaning on, be stable.
Make it that its welding structure is more firm, multiple solder joints 3 are distributed on the peripheral part 12 of bearing main body 1.Solder joint 3
It is uniformly arranged, and area rigid corresponding to each solder joint 3 is suitable, evenly, therefore its welding structure is more firm for the shaft strength.
