Description

Linear compressor support construction

Technical field

The utility model relates to linear compressor technical fields, more particularly to a kind of linear compressor support construction.

Background technique

Linear compressor does the harmonic moving in rectilinear direction using linear motor driving simple harmonic quantity mechanism.As shown in Figure 1, straight Line motor part is made of outer stator components 21, inner stator part 23 and mover component 22, and mover component 22 is located at interior external stator Between component 23 and outer stator components 21.Outer stator components 21 are placed on cylinder seat 1, the right side of outer stator components 21 is placed default Subassembly 23 and support construction 6, support construction 6 are nested in the inside of inner stator part 23.First supporting screw 41 passes through first 31 connection cylinder seat 1 of support.Second supporting screw component 42 passes through the second support 32 and 22 end of mover component again with first The first resonant springs 51 and the second resonant springs 52 are placed in 31 connection of support, the two sides of 22 end of mover component.Second support spiral shell The cantilever beam structure similar with presentation after 31 connection of the first support of screw assembly 42.Screwing force is being applied to the second supporting screw component 42 In the case where square, the first 31 outer rim warpages of support cause the spacing of the second supporting screw component 42 to become smaller, lead to the second support 32 It is not easy to assemble with the second supporting screw component 42.After tightening the first supporting screw 9, second be mounted in the first support 31 is supported The tail end of screw assembly 42 is shunk to central axis direction, simultaneously results in the beat of mover component 22, causes mover portion The non-uniform air-gap of part 22 and inner stator part 23, outer stator components 21.As shown in Fig. 2, current support construction 6 is by muti-piece ring Shape silicon steel sheet 61 is spliced into class tube structure, and is positioned and connected by circlip 62, and the both ends of silicon steel sheet 61 is made to accept the One support 31 and outer stator components 21, and eventually by the first support 31 of the first supporting screw 41 connection and cylinder seat 1, completion pair The axially position of linear motor.The support construction 6 needs muti-piece ring-shaped silicon steel sheet 61 to be assembled, and packaging efficiency is low；Muti-piece ring The high consistency of shape silicon steel sheet 61 is not easy to guarantee；Bearing area of the support construction 6 at the first supporting screw 41 is smaller, Support effect is poor；Circlip 62 has the risk to fall off.

Utility model content

The purpose of this utility model is to provide a kind of linear compressor support constructions, solve " current support construction It is easily-deformable after assembly, assembling parts higher cost and reliability is poor " the technical issues of.

The utility model provides a kind of linear compressor support construction, including upper ring cap, and the cross section of upper ring cap is ring Shape structure, more support rods of lower end spaced set of upper ring cap, support rod and upper ring cap be casting integrated molding, support rod and The outer wall of upper ring cap offers U-lag up and down, and there are excessively oily spaces between adjacent support rod.

Further, the upper ring cap and support rod are made of non-magnet material.

Further, the upper ring cap and support rod are made of casting aluminium material.

Further, the linear compressor support construction further includes lower ring set, and the cross section of lower ring set is ring junction Structure, support rod connect the upper end of lower ring set, and support rod, upper ring cap and lower ring set are casting integrated molding, under the U-lag perforation Ring set.

Further, the upper ring cap, support rod and lower ring set are made of non-magnet material.

Further, the upper ring cap, support rod and lower ring set are made of casting aluminium material.

Further, the quantity of the support rod is four.

Compared with prior art, the linear compressor of the utility model is had the characteristics that and advantage with support construction:

The linear compressor support construction of the utility model, it is high in linear motor rear support intensity being assembled, surely Qualitative height, is unlikely to deform, and avoids motor gas-gap uneven；Support construction is integrally formed, and number of parts significantly reduces, and reduces The assembling cost of part, assembly efficiency is high, improves the reliability of complete machine.

After specific embodiment of the present utility model is read in conjunction with the figure, it will become more the characteristics of the utility model with advantage Add clear.

Specific embodiment

Embodiment one

As shown in figure 3, simultaneously combined with Figure 1 and Figure 2, the present embodiment provides a kind of linear compressor support construction, including it is upper Ring set 71, the cross section of upper ring cap 71 are ring structure, four support rods 72 of lower end spaced set of upper ring cap 71.Upper ring cap 71 and support rod 72 be made of non-magnet material.The preferred casting aluminium material of non-magnet material in the present embodiment, can effectively reduce vortex Loss.Support rod 72 and upper ring cap 71 are casting integrated molding, and production easy to process is suitable for mass production.Support rod 72 and on The outer wall of ring set 71 offers U-lag 81 up and down, is used to penetrate the first supporting screw 41 in U-lag 81.Adjacent branch There are excessively oily spaces 82 between strut 72, and refrigerator oil can be passed through from excessively oily space 82, to realize the cooling to motor, and The use of part material can also be reduced by crossing oily space 82.

The linear compressor of the present embodiment substitutes current support construction 6 with support construction, and support strength is high, stability Height, support construction and the first support 31 are unlikely to deform, and do not influence the assembly of the second support 32 and the second supporting screw component 42, Avoid the mover component 22 and inner stator part 23,21 non-uniform air-gap of outer stator components of motor；Support construction is integrally formed, Number of parts significantly reduces, and reduces the assembling cost of part, and assembly efficiency is high, improves the reliability of complete machine.

Embodiment two

As shown in figure 4, being in place of the present embodiment and the difference of embodiment one, linear compressor further includes with support construction Lower ring set 73, the cross section of lower ring set 73 are ring structure, and upper ring cap 71 connects the upper end of lower ring set 73 through support rod 72.Upper ring Set 71, support rod 72 and lower ring set 72 are made of non-magnet material, and non-magnet material in the present embodiment is it is also preferred that casting aluminium material. Support rod 72, upper ring cap 71 and lower ring set 73 are casting integrated molding.U-lag 81 continues to penetrate through lower ring set 73 downwards.

The linear compressor support construction of the present embodiment increases lower ring set 73, makes support rod 72, upper ring cap 71 and lower ring Set 73 is integrally formed, and can be further improved support strength and stability.
