In some embodiments of the utility model, the support of bearing 110 includes rack body 111 and stabilizer blade 113, holder sheet
Body 111 is configured to slab construction, and stabilizer blade 113 is two and is separately positioned on the both ends of rack body 111.It is understood that
The structure of two stabilizer blades 113 can be identical, and two stabilizer blades 113 are arranged at the both ends of rack body 111 and to far from rack body
111 direction extends, and the extending direction of two stabilizer blades 113 is consistent.
Further, stabilizer blade 113 is configured to " L " shape, and stabilizer blade 113 includes first segment 113a and second segment 113c, first segment
113a, which is arranged, on the support of bearing 110 and to be extended downwardly, and second segment 113c is arranged in the free end of first segment 113a and to extension
It stretches.
Firstly the need of explanation, the "inner" in the utility model embodiment refers to the center position towards rack 100,
"outside" refers to the center position far from rack 100.
The first segment 113a of two stabilizer blades 113 is extended downwardly, and two second segment 113c are separately positioned on corresponding first
It the free end of section 113a and is directed away from mutual direction and extends.
Further, the lower surface of second segment 113c and the axis vertical take-off of brearing bore 103 are arranged.In the utility model
Specific example in, brearing bore 103 extends in the vertical direction, the lower surface in order to ensure second segment 113c and brearing bore
103 axis vertical take-off, therefore the lower surface of second segment 113c is parallel with horizontal plane, i.e., the lower surface of second segment 113c is in level side
To extension.
In some embodiments of the utility model, as shown in Figures 2 and 3, brearing bore 103 includes the set gradually
Hole section 103a in one, hole section 103e in hole section 103c and third in second, wherein the aperture of hole section 103c is more than first in second
The aperture of hole section 103e in the aperture of interior hole section 103a and third.
In the specific example of the utility model, brearing bore 103 is followed successively by hole section 103a, second in first from top to bottom
Hole section 103e in interior hole section 103c and third.Hole section 103c settings hole section 103e in hole section 103a and third in first in second
Between.Brearing bore 103 is configured to the structure that interstitial hole is wealthy, both ends of the hole is narrow.
The bent axle that hole section 103c will not be with cooperation in brearing bore 103 in second as a result, is in contact, and greatly reduces axis
The hole wall of endoporus 103 and the contact area of bent axle are held, the friction power loss between bent axle and brearing bore is reduced, to which bent axle can
It is more rapidly rotated on bearing 130, improves the performance of compressor.
In some embodiments of the utility model, the axis of bearing mounting hole 101 and the axis weight of brearing bore 103
It closes.Bearing 130 can be more fixedly mounted in bearing mounting hole 101 as a result,.Optionally, bearing 130 and bearing mounting hole
101 inner wall is welded and fixed.
The reciprocating compressor of the utility model embodiment is briefly described below.
Reciprocating compressor according to the utility model embodiment includes the rack 100 of above-described embodiment, due to according to this
The reciprocating compressor of utility model embodiment is provided with above-mentioned rack 100, therefore the compressor difficulty of processing is low, and at least exists
The production efficiency for improving compressor to a certain extent reduces the manufacturing cost of compressor.
The processing of the rack 100 for reciprocating compressor of the utility model embodiment is described in detail with reference to Fig. 4
Method.
Rack 100 in this method may include the support of bearing 110 and bearing 130, is provided with along it on middle (center) bearing 130
Axially extending brearing bore 103.
Bearing mounting hole 101 is provided on the support of bearing 110, the support of bearing 110 includes rack body 111 and stabilizer blade 113,
Stabilizer blade 113 is two and is separately positioned on the both ends of rack body 111, and stabilizer blade 113 is configured to " L " shape and includes first segment 113a
It is arranged on the support of bearing 110 and extends downwardly with second segment 113c, first segment 113a, second segment 113c is arranged in first segment
The free end of 113a and extend outwardly.
The processing method of rack 100 includes the following steps：
First, bearing 130 is extend into bearing mounting hole 101, bearing 130 is then weldingly fixed on the support of bearing
On 110；
Secondly, on the basis of the outer diameter of bearing 130, right boring is carried out to brearing bore 103.Thus, it is possible to brearing bore
103 carry out roughing, reduce due to the deformation in bearing 130 and 110 welding process of the support of bearing.
Again, on the basis of brearing bore 103, the lower surface of fine grinding second segment 113c so that brearing bore 103 axis
Line is perpendicular to the lower surface of second segment 113c；Thereby it is ensured that hanging down between brearing bore 103 and the lower surface of second segment 113c
Straight degree.
Finally, on the basis of the lower surface of second segment 113c, the smart top gem of a girdle-pendant is carried out to brearing bore 103.To further increase
The precision of brearing bore 103, ensure bent axle can rotate in 103 high speed of brearing bore, and do not interfere with brearing bore 103 and
Verticality between the lower surface of second segment 113c.
According to the processing method of the above-mentioned rack 100 of the utility model embodiment, the processing technology of rack 100 is simplified,
Reduce the rejection rate and processing cost of rack 100.
It, can be to bearing before bearing 130 is welded on the support of bearing 110 in some embodiments of the utility model
Endoporus 103 be machined so that the stage casing part of brearing bore 103 internal diameter be more than brearing bore 103 both ends part it is interior
Diameter.
It is, of course, understood that can also be after bearing 130 be welded on the support of bearing 110 and to brearing bore
103 carry out right borings before, to brearing bore 103 be machined so that brearing bore 103 stage casing part internal diameter be more than bearing
The internal diameter of the both ends part of endoporus 103.
The stage casing part of brearing bore 103 is configured to hole section 103c in second in above-described embodiment, brearing bore 103
Both ends part is respectively configured in first in above-described embodiment hole section 103e in hole section 103a and third.Brearing bore as a result,
103 stage casing part will not be contacted with bent axle, reduce the hole wall of brearing bore 103 and the contact area of bent axle, reduce bent axle
Friction power loss between brearing bore so that bent axle can be rotated more rapidly in brearing bore 103.
