Abstract

The utility model discloses a compressor, comprising a blade and a blade groove. The surface of the blade groove is equipped with at least one needle roller. The contact mode between the blade and the surface of the blade groove is rolling contact. The effect of the utility model's beneficial technology is characterized in the reduced abrasion between the blade and the blade groove's internal surface, reduced compressor's input power loss and improved compressor's reliability.

Description

A kind of compressor
[technical field]
The utility model relates generally to field of Refrigeration and Air-conditioning, especially a kind of compressor.
[background technique]
As shown in Figure 1, existing rolling rotor type compressor mainly comprises cylinder 2, blade 5, piston 3, eccentric crankshaft (figure does not show) etc.Motor drives piston 3 eccentric rotary by eccentric shaft, finishes the work cycle of gas suction-compression-discharge, and exhaust is discharged through angular cut 1, exhaust port (figure does not show) from compression chamber (hyperbaric chamber) 8.Upper cylinder cover (figure does not show), cylinder, piston 3, blade 5 (or claiming slide block), following cylinder cap (figure does not show) form swept volume, blade 5 is done the motion that reciprocatingly slides by being supported in of spring in the cylinder, the cylinder internal volume is divided into low pressure (air-breathing) chamber 7 and high pressure (compression) chamber 8.Fig. 2 has listed all power that acts on the blade 5: and the contact force Fn and the Ft of 3 in piston; And the contact force FR1 that blade groove is 4, FR2 and FRt1, FRt2; The elastic force Fk of blade 5 springs; The inertial force FIv of blade 5; And act on the power that gas or lubricating oil pressure caused around the blade 5 etc.Blade 5 is stretched the part in cylinder owing to bear that difference force Fh can occur bending and deformation and blade groove 4 internal surface contact-impacts, moves back and forth in the process at blade 5 and weares and teares, as A place among Fig. 2 and B place; Blade 5 tightly is being pressed under the effect of back pressure and spring force on piston 3 outer surfaces, and along with the rotation of piston 3 at the cylinder intercycle, blade 5 weares and teares, and as the C place among Fig. 2, finally causes the compressor power input loss to increase or inefficacy.
[summary of the invention]
The purpose of this utility model is to provide a kind of compressor, reduces the wearing and tearing between blade and the blade groove internal surface, reduces the loss of compressor power input, improves compressor reliability.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is: a kind of compressor, comprise blade and blade groove, and described blade groove internal surface is provided with at least one needle roller, and described blade contacts for rolling with the blade groove way of contact.
Preferred version of the present utility model is: described blade is provided with at least one needle roller on the top near compressor piston.
Preferred version of the present utility model is: described blade groove internal surface and blade tip are provided with perforate, are provided with needle roller in the described perforate, and the described rolling way of contact is the face contact.
Preferred version of the present utility model is: described perforate is a circular hole.
Preferred version of the present utility model is: described blade tip is a circular arc type
Preferred version of the present utility model is: described blade groove internal surface and blade tip are provided with fluting, are provided with needle roller in the described fluting, and the described rolling way of contact is the some contact.
Preferred version of the present utility model is: described fluting is a contract type groove.
Preferred version of the present utility model is: described top is flat pattern.
Preferred version of the present utility model is: described compressor is a rolling rotor type compressor.
Preferred version of the present utility model is: described compressor is a rotary compressor.
Beneficial technical effects of the present utility model is: compressor of the present utility model is after blade and blade groove internal surface, blade and outer surface of piston are by one or more needle rollers of packing into, the way of contact that makes blade and blade groove internal surface, blade and outer surface of piston is contacted by sliding friction and becomes the rolling friction contact, wearing and tearing have been reduced, reduce the loss of compressor power input, improved the reliability of compressor; Simultaneously, the requirement of piston material has just been reduced, can use the lower material of wear resistance to make, provide cost savings, and the frictional loss of crankshaft eccentric portion and piston inner diameter also can significantly reduce.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
The structural representation that Fig. 1 slides in blade groove for the blade that has compressor now;
Fig. 2 is the existing stressed schematic representation of compressor blade;
Fig. 3 is the utility model compressor one embodiment's a structural representation;
Fig. 4 is another embodiment's of the utility model compressor a structural representation;
[embodiment]
Core concept of the present utility model is: the new structure compressor of a kind of blade with rolling way of contact campaign is provided, in this compressor blade and blade groove internal surface, blade and outer surface of piston by one or more needle rollers of packing into after, its way of contact becomes the contact of rolling, to reduce the wearing and tearing between blade and blade groove internal surface, blade and the outer surface of piston, reduce the loss of compressor power input, improve compressor reliability.
See also Fig. 3, be compressor one embodiment's of the present utility model structural representation.Compressor of the present utility model comprises blade groove 12, piston 13 and is arranged on blade 14 in the blade groove 12.Blade groove 12 internal surface two-end-point places open a circular hole 15 respectively, and a needle roller 11 is housed respectively in the circular hole 15; Blade 14 is offered a circular hole 15 too near piston 13 end faces, and a needle roller 11 also is housed in this through hole.The way of contact of blade 14 in cylinder blade groove 12 just become the contact of rolling, and blade 14 end faces have also become rolling with piston 13 outer surfaces and contacted.In the above-described embodiments, blade 14 tops are circular arc type.
See also Fig. 4, be another embodiment's of compressor of the present utility model structural representation.Compressor of the present utility model comprises cylinder blade groove 12, piston 13 and is arranged on blade 14 in the cylinder blade groove 12.Blade groove 12 internal surface two-end-point places are provided with a contract type groove 16 respectively, in this contract type groove 16 needle roller 11 are housed respectively; Blade 14 is offered a contract type groove 16 too near piston 13 end faces, in this contract type groove 16 needle roller 11 is housed also, and the face on needle roller 11 and blade groove 12 internal surfaces and blade 4 tops contacts and changes a contact into.In the above-described embodiments, blade 14 tops are flat pattern.
By blade in compressor 14 and blade groove 12 internal surfaces, blade 14 and piston 13 outer surfaces by one or more needle rollers 11 of packing into after, the friction of blade 14 and piston 12 outer surfaces has become rolling friction by sliding friction, requirement to piston 12 materials has just reduced, so the material that can use wear resistance to hang down some is made, the frictional loss of crankshaft eccentric portion and piston 12 internal diameters simultaneously also can significantly reduce.
Compressor of the present utility model is a rotary compressor, and particularly rolling rotor type compressor also can be the compressor of other types.
The above; it only is the preferable concrete true mode of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
