Description
[technical field]
The utility model relates to a kind of refrigeration compressor ball seat piston and ball link assembly, belongs to the refrigerant compression apparatus field.
[background technique]
In the chiller plant such as refrigerator, refrigerator, the piston of Totally-enclosed piston type compressor is normally made flexible reciprocal straight line motion under the drive of the connecting rod of crank-driven.In the prior art, the spherical accommodating part of piston and ball link dependence internal piston and the spherical head of ball link are rotatably assorted and reduce the external force interference that bent axle is swung the on-rectilinear movement direction of bringing.Because spherical accommodating part need hold the overwhelming majority of spherical head, and its opening is installed to wherein so require the structure of spherical accommodating part to be convenient to spherical head less than the spherical head diameter, and can guarantee that still fitting surface cooperates flexibly with spherical head after installing.The spherical accommodating part of existing structure is generally 2 stamping part that have flange and involutes, need after the spherical head of packing into, the flange of 2 stamping part be fixed, spherical head can be installed to wherein though satisfy, but complex operation, the difficulty height, make stamping part distortion or fitting surface smooth degree reduce toward the contact meeting, influence spherical accommodating part and cooperate with the flexible of spherical head.
[model utility content]
The technical assignment of the technical problems to be solved in the utility model and proposition is the defective that overcomes prior art, provide a kind of be easy to the highi degree of accuracy manufacturing, the assembling spherical head convenient, ball link rotate refrigeration compressor ball seat piston and ball link assembly flexibly.For this reason, the utility model adopts following technological scheme:
Refrigeration compressor ball seat piston and ball link assembly, comprise piston and ball link with spherical head, it is characterized in that in the described piston being that cavity and cavity top are provided with the boss of being inverted the band inner sunken face, the madial wall of described piston is provided with the groove of ring-side wall near opening, be provided with jump ring in the groove, jump ring is put on the shelf and is provided with the ball packing ring of annular, be provided with between described boss and the ball packing ring and be coated on the outer spherical crown shape ball of spherical head watt, the height that described ball watt-minute is a spherical crown surface equals the last ball watt of radius and at the lower ball tile of the ring-type of outer surface and its welding.Piston of the present utility model is by inner sunken face and ball packing ring on the boss of fitting with ball watt outer surface, limits ball watt from both direction and left and right directions up and down, thereby by placing the spherical head in the ball watt to move with ball link.With respect to prior art flange is set, the utility model relies on inner concave and ball packing ring to limit the position of ball watt, so do not need to set up flange, reduced the stretching of machining to ball watt, just reduced because of stretching and be out of shape influence precision, ensured ball watt smoothness as the internal surface of fitting surface, and kept ball in the prior art split manufacturing watt, lower ball tile easy processing, easily assembling, can adjust advantage such as precision respectively.Last ball watt, lower ball tile welding are fixing, and ball watt deformation does not take place substantially, can guarantee that assembling back spherical head can rotate on the fitting surface that last ball watt, lower ball tile combine flexibly, and the reduction bent axle is swung the external force interference of the on-rectilinear movement direction of bringing.Such structure, in installation process, earlier, make a ball watt aligning inner sunken face insert in the cavity of piston pack into successively again ball packing ring, jump ring then with upper and lower ball watt spherical head assembling with ball link, assemble very quick, ball link and ball watt wearing and tearing to some extent after using a period of time, and have influence on piston motion, can take out ball packing ring and jump ring, carry out part and change, also aspect working service, provide convenience.
For the improving and replenishing of technique scheme, can increase following technical characteristics or its combination:
Describedly go up ball watt, lower ball tile is provided with the lubricant oil through hole, has oil leab on the surface of contact of described ball packing ring and spherical head.Like this fitting surface of the upper and lower ball of Castor Oil watt and spherical head, with the surface of contact of inner sunken face, ball packing ring, when even ball watt and spherical head occur the situation of relative displacement does not take place, the outer surface of last lower ball tile still can rely between lubricant oil and inner sunken face, the ball packing ring and be moved, and equally also can play the external force of the on-rectilinear movement direction that reduction bent axle swing to a certain degree brings and disturb.
Described groove top and bottom sidewall is provided with the place-limited edge to piston central direction projection.Usually the very thin discomfort of piston wall is run deep trouth jointly, can increase the degree of depth of groove by setting up two place-limited edges, satisfies installation requirements, the displacement of restriction jump ring.
Described ball packing ring is that metallic material is made.During assembling, can bear big extruding force, make ball watt very close to each other, prevent that piston and ball Orostachys fimbriatus from moving with piston.
The described curvature that goes up ball watt is identical with inner sunken face.The position that helps to limit ball watt do not change and a stable condition under, the rotation that ball watt can be on inner sunken face reduces ball link applies power to piston on the on-rectilinear movement direction interference.
The spherical head of described ball link is welded on the connecting rod.Be convenient to the split manufacturing, improve element precision.
The utility model comes position from upper and lower and left and right direction restriction ball watt by boss, ball packing ring are set, thereby upper and lower ball watt does not need to be provided with flange, reduced in metal stretching and the fixation procedure influence degree to the two precision, up-to-standard rate improves, and assembly manipulation is simple, and assembly process watt does not almost have the deformation influence to ball, thereby has ensured that ball link can rotate in ball watt flexibly, the part of replaceable loss in the using process is convenient to safeguard.
