Abstract
The invention discloses a slide vane of a compressor. A main body of the slide vane is approximately in the shape of a cuboid; a spring slot is arranged on one side of the slide vane; a U-shaped slot is arranged on the opposite side of the spring slot of the slide vane; a cylindrical roller pin is arranged in the U-shaped slot and can roll in the U-shaped slot; and the external diameter of the roller pin is greater than the depth of the U-shaped slot. The slide vane has the advantages that the roller pin is arranged in the U-shaped slot of the slide vane, so that rolling friction is formed between the slide vane and a rotating piston, the energy consumption by friction of the slide vane is reduced, the energy utilization rate is improved, and the roller pin can be prevented from being separated from the upper part of the U-shaped slot with the adoption of an opening on the side of the U-shaped slot.
Description
Technical field
The present invention relates to a kind of compressor part, particularly a kind of slide plate that is used for rotary compressor.
Background technique
Rotary compressor is also referred to as sliding-vane compressor, and its main frame mainly is made up of rotating piston and stator, and stator is a cylinder block, and rotor is eccentric the placement in stator.Be provided with slide plate between rotor and cylinder block, change, continue to suck and compression thereby accomplish medium because of rotor rotation makes the cylinder volume of slide plate two sides.Because sliding-vane compressor is simple in structure, efficient is high, the operation and maintenance easy maintenance, work is tranquil, vibration is little, so sliding-vane compressor is used widely.
Existing compressor sliding blade is as shown in Figure 1, and the dovetail groove 71 on the slide plate 7 is used for mounting spring, and the contact position of slide plate and rotating piston is a circular arc type; Because be sliding friction between the two; Increased the consumption of energy, increased the rotor wear amount, be necessary to improve.
Summary of the invention
Technical problem to be solved by this invention is to overcome the above-mentioned deficiency of existing technology and a kind of compressor sliding blade is provided, and makes it can reduce the energy that the slide plate friction is consumed, and improves capacity usage ratio, reduces the wear extent of rotating piston.
The present invention addresses the above problem the technological scheme that is adopted: a kind of compressor sliding blade; Body shape is roughly cuboid; Have spring groove on the side wherein, it is characterized in that: said sliding blade spring groove opposing side has U-groove bevel, places cylindrical needle roller in the U-groove bevel; Needle roller can roll in U-groove bevel, and the external diameter of needle roller is greater than the degree of depth of U-groove bevel.
The U-groove bevel side of above-mentioned slide plate is provided with spacing closing in, and closing in is two pairs, on the side that is distributed in U-groove bevel of symmetry, closes up and outstandingly to stretch to U-groove bevel top, prevents that needle roller from deviating from from U-groove bevel top.
Compared with prior art, the invention has the advantages that:
1, has U-groove bevel in the one side of slide plate; Be used in the cylindrical needle roller that can in U-groove bevel, roll in the compressor, needle roller exposes outside U-groove bevel, and making the friction mode between slide plate and the piston is rolling friction; Reduce because of the energy that consumed of friction; Improve capacity usage ratio and compressor efficiency, reduce the wear extent of rotating piston simultaneously, prolong service life of a machine.
2, the groove side is provided with spacing closing in, can prevent that needle roller from coming off from the U-groove bevel upper opening.
Description of drawings
Fig. 1 is the slide vane structure schematic representation of existing compressor.
Fig. 2 is a slide vane structure schematic representation of the present invention.
Fig. 3 is slide plate of the present invention and needle roller assembling schematic representation.
Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Like Fig. 2, the slide vane structure for the present invention relates to shown in Figure 3, the body shape of slide plate 1 is a rectangular, has U-groove bevel 11 on one of them face; Place cylindrical needle roller 2 in the U-groove bevel 11, the equal in length of the length of needle roller 2 and U-groove bevel 11, the external diameter of needle roller 2 is greater than the degree of depth of U-groove bevel 11; Make needle roller 2 expose outside U-groove bevel 11; Needle roller 2 can roll in U-groove bevel 11, and in slide plate 1 was packed stator into, the needle roller 2 in the slide plate 1 was close to the cylndrical surface of rotating piston; Make and be between the two rolling friction to reduce the abrasion of friction energy loss and rotating piston.
U-groove bevel 11 was radius circular U-groove bevels, and it can make cylindrical needle roller 2 put into and portion's rolling within it.
On U-groove bevel 11 sides, be provided with spacing closing in 12, closing in 12 is given prominence to and is stretched to U-groove bevel 11 tops, during assembling, can needle roller 2 be inserted from an end of U-groove bevel 11, and the protuberance steric hindrance retaining needle roller 2 of closing in 12 comes off from the top of U-groove bevel 11.
For preventing needle roller 2 perk or excessive loosening in U-groove bevel 11, spacing closing in 12 is arranged to two pairs, and symmetrical is distributed on U-groove bevel 11 sides, and how right can certainly be arranged to.
Have spring groove 13 in the relative face of said slide plate U-groove bevel 11; Be used to place spring; When making the rotor rotation, the needle roller 2 in the slide plate U-groove bevel 11 is adjacent to the rotating piston periphery all the time, for stability and the balance that guarantees slide plate 1; Spring groove 13 is one or more, and it is trapezoidal, square that shape can be etc.
Claims (3)
1. compressor sliding blade, body shape is roughly cuboid, has spring groove on the side wherein; It is characterized in that: said sliding blade spring groove opposing side has U-groove bevel; Place cylindrical needle roller in the U-groove bevel, needle roller can roll in U-groove bevel, and the external diameter of needle roller is greater than the degree of depth of U-groove bevel.
2. compressor sliding blade according to claim 1 is characterized in that: the U-groove bevel side of said slide plate is provided with spacing closing in, the outstanding U-groove bevel top of stretching to of closing up, and the restriction needle roller is deviate from from U-groove bevel top.
3. compressor sliding blade according to claim 2 is characterized in that: said spacing closing in is two pairs, on the side that is distributed in U-groove bevel of symmetry.
