Description
Technical field
The present invention relates to a kind of refrigerator Totally-enclosed-type motor compressor, more particularly to a kind of refrigerator Totally-enclosed-type are electronic
Compressor and its bent axle.
Background technology
The of high cost of compressor, oil extraction become greatly the short slab of generally existing in industry, and how to reduce cost, the row of reduction
Oil mass has become one of problem that compressor industry needs solve.General refrigeration compressor for refrigeration is mainly by motor, machine
Tool moving component and shell body three parts composition, wherein mechanical moving element mainly has bent axle, connecting rod, piston, cylinder seat etc.
Form, and bent axle is the hinge for connecting motor and mechanical moving element, motor rotor band dynamic crankshaft rotates, and bent axle driving connects
Other moving components work such as bar;And the performance boost of compressor can be directly related with bent axle, bent axle is moving component, dragging pressure
Contracting machine connecting rod and reciprocating motion of the pistons, so bent axle and the even running inside compressor, the close phase of the discharge rate of refrigerator oil
Close;And the performance boost of compressor, the even running of mechanical moving element, the amount of refrigerator oil discharge, the bent axle of different structure
Role is also different.
There is the problem of manufacture is of high cost, and processing technology is difficult with bent axle in existing motor compressor, and existing mostly
Motor compressor is to reach lubricant effect on the external peripheral surface of bent axle generally to offer finishing bathtray with bent axle, is matched somebody with somebody with compressor
After closing use, refrigerator oil discharge rate can be caused big.It can be seen from the above that the prior art is up for further improving.
The content of the invention
The present invention is to avoid above-mentioned the shortcomings of the prior art part, there is provided a kind of electronic pressure of refrigerator Totally-enclosed-type
Contracting machine and its bent axle, the crankshaft structure change the fuel-displaced route of compressor, reduce oil extraction.
The technical solution adopted in the present invention is:
Totally-enclosed-type motor compressor bent axle, including main shaft section and relative to main shaft section center line arranged off-centre it is inclined
Heart section, the inside of main shaft section offer axial center hole, eccentric segment oil outlet are offered on eccentric segment, and the inside of eccentric segment opens up
There is an oblique oil discharge passage, one end of oblique oil discharge passage is connected with eccentric segment oil outlet, the other end is connected with axial center hole
It is logical.
The angle of the interplanar at the central axes of the eccentric segment oil outlet and the cylindrical place of eccentric segment is obtuse angle.
Angle between the axis of the oblique oil discharge passage and the axis of axial center hole is obtuse angle.
The internal diameter of the oblique oil discharge passage is less than the internal diameter of axial center hole.
The ellipsoidal cross section of the eccentric segment oil outlet.
The invention also discloses a kind of refrigerator Totally-enclosed-type motor compressor, it includes bent axle as described above.
By adopting the above-described technical solution, having the beneficial effect that acquired by the present invention:
1st, the outer cylinder surface of main shaft section and the outer cylinder surface of eccentric segment do not have oil groove in the present invention, simplify processing
Process, reduces production cost.
2nd, eccentric segment oil outlet is connected by oblique oil discharge passage and the axial center hole of main shaft section in the present invention, is changed
The fuel-displaced route of original compressor, lubrication effect can be ensured without the slot structure that oils on bent axle outer surface by not only reached
Fruit, and the discharge rate of refrigerator oil can be reduced, there is more preferable using effect compared to existing compressor bent axle, and improve
The overall performance of compressor.
3rd, for traditional eccentric segment oil outlet more by the way of oblique oil groove or oilhole exit process big chamfering, use is such a
During the technique processing bent axle that diameter is small, offset is small, there are the defects of oil groove broken wall, easy overhauling;Eccentric segment in the present invention
Oil outlet uses new processing technology, i.e., by the way of eccentric part external cylindrical surface material is directly cut off, it is possible to reduce edge hair
The bad products rate such as thorn, broken wall.
4th, the configuration of the present invention is simple, easy for installation, easy mass production, cost-effective, bad products rate is low.

Fig. 1 is the axonometric drawing of the present invention.
Fig. 2 is the front view of eccentric segment in the present invention.
Fig. 3 is the front view of the present invention, wherein, dotted portion shows the opposite of oblique oil discharge passage and axial center hole
Position relationship.
Wherein,
1st, main shaft section 2, eccentric segment 3, axial center hole 4, oblique oil discharge passage 5, eccentric segment oil outlet
Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but the present invention is not limited to
These embodiments.
As shown in Figure 1 to Figure 3, Totally-enclosed-type motor compressor bent axle, including main shaft section 1 and relative to main shaft section 1
The eccentric segment 2 of center line arranged off-centre, the inside of main shaft section 1 offer axial center hole 3, eccentric segment are offered on eccentric segment 2
Oil outlet 5, the ellipsoidal cross section of eccentric segment oil outlet 5.The central axes of the eccentric segment oil outlet 5 are cylindrical with eccentric segment 2
The angle of the interplanar at place is obtuse angle, which can not only reduce the friction between eccentric segment 2 and compressor inside connecting rod,
And the structure type at big obtuse angle can efficiently reduce the defective products rate such as burr, broken wall at eccentric segment oil outlet 5.The bias
The inside of section 2 offers oblique oil discharge passage 4, and one end of oblique oil discharge passage 4 is connected with eccentric segment oil outlet 5, the other end
It is connected with axial center hole 3, this kind of structure type can not only be lubricated compressor, but also can make the row of compressor
Oil mass is preferably minimized.The internal diameter of the oblique oil discharge passage 4 is far smaller than the internal diameter of axial center hole 3.It is described oblique fuel-displaced logical
Angle between the axis in road 4 and the axis of axial center hole 3 is obtuse angle.The structure design of above-mentioned bent axle is particularly suitable for realizing
1 outside diameter 18mm of main shaft section, 2 outside diameter 16mm series of eccentric segment crankshaft structure upper oil lubrication.
The invention also discloses a kind of refrigerator Totally-enclosed-type motor compressor, it includes bent axle as described above.Assembling
During compressor, above-mentioned bent axle is cold-pressed the rotor shaft hatch into compressor, after power supply is powered, the rotation of rotor banding dynamic crankshaft, bent axle band
Dynamic connecting rod and reciprocating motion of the pistons, so as to fulfill the work of compressor.
The invention also discloses a kind of refrigerator Totally-enclosed-type motor compressor, it includes bent axle as described above.
