Abstract
The invention discloses a kind of crankshaft structure of rotary compressor. It includes crankshaft, eccentric part rotated turned with the crankshaft, and rolling hoop. Fillister is set on the contact surface of the outer circumference surface of the eccentric part and the rolling hoop to reduce the contact area. The fillister set on the outer circumference surface is formed to annularity, from one to three fillisters are set. The advantage of the invention is that the structure of the eccentric part of the crankshaft of the rotary compressor is improved; because of the fillister is set on the contact surface of the outer circumference surface of the eccentric part and the rolling hoop to reduce the contact area; this makes the contact area of the eccentric part and the inner surface of the rolling hoop being reduced to reduce the friction and decrease the load, as well as decrease the noise.
Description
Technical field
The invention relates to compressor, particularly be the rotary compressor crankshaft structure.
Background technique
The prior art rotary compressor includes: housing 1, the motor section that the inside of housing 1 is made up of stator 2 and rotor 3; Bottom at compressor comprises: there is the cylinder 8 of certain space pressing chamber inside; Perforation is pressed into fixed crankshaft 4 in the inside of rotor 3, and upper bearing 5 and the lower bearing 6 that can support bent axle 4 are arranged, and upper bearing 5 and lower bearing 6 usefulness rigid bearing screws 7 are fixing, and the top of upper bearing 5 is provided with the baffler 12 that reduces exhaust noise.Be provided with eccentric part 4a between upper bearing 5 and the lower bearing 6, and be formed with the cylinder 8 that connects suction passage with radiation shape; Roll the outer circumferential face that the contact of ring 9 inner faces is located at bent axle one end eccentric part 4a, roll the inner face that ring 9 outer circumferential faces are contacted with cylinder 8, do revolution and spinning motion by the rotation of eccentric part 4a.The top of compressor case 1 loam cake 1 is provided with outlet pipe 15, and the liquid storage of compressor case 1 one sides is irritated 13 tops and is provided with sucking pipe 14.Oil is arranged at the bottom of bent axle 4, oil is input to oil circuit in the bent axle 4 by the oil circuit import, oil is input to eccentric part 4a and the surface of contact that rolls ring 12 by the oil circuit outlet of eccentric part 4a, be lubricated, bent axle 4 when rotated, because eccentric part 4a and to roll ring 12 inner face surface of contact bigger is easy to generate friction, increases load.
Summary of the invention
In order to solve the problem that above-mentioned technology exists, the invention provides a kind of rotary compressor crankshaft structure, make eccentric part and roll ring 12 inner face surface of contact to reduce, reach the purpose of reducing friction and reducing load.
To achieve these goals, the technical solution used in the present invention is:
Comprise bent axle, the eccentric part that rotates with bent axle and roll ring is at the outer circumferential face of eccentric part with roll ring and be in contact with one another groove is set on the face, to reduce area of contact.
Above-mentioned groove is located on the eccentric part outer circumferential face in the form of a ring.
On the eccentric part outer circumferential face, establish 1 groove.
On the eccentric part outer circumferential face, establish 2 grooves.
On the eccentric part outer circumferential face, establish 3 grooves.
The invention has the beneficial effects as follows: rotary compressor crankshaft eccentric bilge construction is improved, because the outer circumferential face at eccentric part is provided with groove with rolling to encircle to be in contact with one another on the face, to reduce area of contact, make eccentric part and roll ring inner face surface of contact to reduce, reach and reduce friction and reduce load.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: comprise bent axle, the eccentric part that rotates with bent axle and roll ring is at the outer circumferential face of eccentric part with roll ring and be in contact with one another groove is set on the face, to reduce area of contact.
Above-mentioned groove is located on the eccentric part outer circumferential face in the form of a ring.
On the eccentric part outer circumferential face, establish 1 groove.
On the eccentric part outer circumferential face, establish 2 grooves.
On the eccentric part outer circumferential face, establish 3 grooves.
As shown in Figure 4, comprise in the bottom of compressor: there is the cylinder 8 of certain space pressing chamber inside; Perforation is pressed into fixed crankshaft 4 in the inside of rotor 3, and upper bearing 5 and the lower bearing 6 that can support bent axle 4 are arranged, and upper bearing 5 and lower bearing 6 usefulness rigid bearing screws 7 are fixing, and the top of upper bearing 5 is provided with the baffler 12 that reduces exhaust noise.Be provided with eccentric part 4a between upper bearing 5 and the lower bearing 6, and be formed with the cylinder 8 that connects suction passage with radiation shape; Roll the outer circumferential face that the contact of ring 9 inner faces is located at bent axle one end eccentric part 4a, roll the inner face that ring 9 outer circumferential faces are contacted with cylinder 8, do revolution and spinning motion by the rotation of eccentric part 4a.Oil is arranged at the bottom of bent axle 4, oil is input to oil circuit in the bent axle 4 by the oil circuit import, oil is input to eccentric part 4a and the surface of contact that rolls ring 12 by the oil circuit outlet of eccentric part 4a, be lubricated, bent axle 4 when rotated, because at the outer circumferential face of eccentric part 4a with roll ring 12 and be in contact with one another groove 4b is set on the face, to reduce area of contact.Above-mentioned groove 4b is located on the eccentric part 4a outer circumferential face in the form of a ring.
Shown in Fig. 3 and 4, on eccentric part 4a outer circumferential face, can establish 1 groove 4b, as illustrated in Figures 5 and 6, also can establish 2 or 3 groove 4b.Thereby can reduce cost, reduce the eccentric part and the surface of contact that rolls ring of bent axle, reduce load, fill lubricant oil among the groove 4b, reduce wearing and tearing, reduce noise simultaneously.
