Abstract
The present invention discloses a bottom triangle of a rotary compressor, which comprises a planar part and supporting ribs; wherein, a through hole and mounting holes, which are used for the mounting of a bottom cover of the compressor, are arranged on the planar part, which is shaped like a circular ring; the through hole is positioned at the center of the circular ring; the mounting holes, which are used for the mounting of the compressor through the bottom triangle, are extended towards the outside of the circular plane at positions on the circular plane at an included angle of 120 degrees; and along one part of the planar part and the mounting holes, the three arc-shaped supporting ribs are positioned on the lower side of one part of the planar part and the mounting holes. The bottom triangle has the following advantages: the improved bottom triangle of the rotary compressor uses only 78.55 percent of material in comparison with the unimproved bottom triangle, thus saving 21.45 percent of the material, and since the arc-shaped supporting ribs are added, the bending strength is greatly enhanced. Under the premise of fully ensuring strength, reinforced ribs are added at corners, and therefore the strengthening effect is more obvious.
Description
Technical field
The present invention relates to compressor, especially the base angle of rotary compressor.
Background technique
Usually, as shown in Figure 1, 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 17 that reduces exhaust noise; Roll the outer circumferential face that the contact of ring 9 inner faces is located at bent axle one end eccentric part, 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.The top of compressor case 1 loam cake 10 is provided with outlet pipe 14, and the liquid storage of compressor case 1 one sides is irritated 11 tops and is provided with sucking pipe 12.Oil is arranged at the bottom of bent axle 4, and oil is input to oil circuit in the bent axle 4 by the oil circuit import, and the oil circuit outlet of oil by eccentric part is input to eccentric part and rolls the surface of contact of ring 9, is lubricated.There is tenminal block 13 in loam cake 10, is connected with stator by circuit.Compressor case 1 bottom and bottom 15 are welded together by circumference, and bottom 15 bottoms and base angle 16 are also by being welded together.
As shown in Figure 2, the base angle of prior art by leg-of-mutton planar surface portion 20 with along each limit of triangle, be positioned at three ribs 21 in planar surface portion 20 belows and constitute, ribs 21 is the lengthy motion picture structure of an entire body, have circular through hole 23 at the center of leg-of-mutton planar surface portion 20, on three angles of leg-of-mutton planar surface portion 20, have perforation, be used for compressor being installed to three mounting holes 22 on the chassis, that insert rubber sheet gasket by base angle 16.In compressor manufacturing process, the bottom 15 of compressor is placed on the through hole 23 by after being welded together, the placement of casing is transported to composing room and is assembled into air-conditioning with miscellaneous part again.Before compressor bank was dressed up final product, compressor was fixed on the base angle 16 because bottom 15 is arcuation, be installed on the base angle 16 after, be supported on the bottom surface by three ribs 21, play the effect of support.But circular through hole 23 is only dug, as shown in Figure 2 in the base angle of prior art 16 at the center of leg-of-mutton planar surface portion 20, the major part of planar surface portion is an entity, has the problem of waste of material, and ribs 21 is a straight line type, and through hole 23 stressed be arc, have the problem of unbalance stress.
Summary of the invention
Technical problem to be solved by this invention provides a kind of base angle of reducing material consumption, improving the rotary compressor of resistance to flexure.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of base angle of rotary compressor, comprise, planar surface portion and ribs, on planar surface portion, have through hole and mounting hole that compressor bottom cap is installed, described planar surface portion is circular, through hole is positioned at the center of annulus, extend outside circular planes in the positions that are in 120 degree on the circular planes and to form three and be used for compressor being installed to mounting hole on the chassis, along the part of planar surface portion and mounting hole, be positioned at three arc ribs of the part below of planar surface portion and mounting hole by the base angle.
Described base angle is a metal material.
The weight of the circular width of described planar surface portion for guaranteeing to bear compressor.
The invention has the beneficial effects as follows: the base angle of rotary compressor of the present invention, improve the back and use material for 78.55% before improving, saved 21.45%; Increase the ribs that has structural bending, increased resistance to flexure greatly.Under the prerequisite of abundant proof strength, use stiffening rib in the corner, stiffening effect is more obvious.
