Abstract
The utility model discloses an insert system of a split type cylinder base of a refrigerator compressor, which comprises a plurality of inserts, wherein at least one bulge or bit is arranged on each insert. As at least one bulge or bit is arranged on each insert, when the split type cylinder base is produced, once the inserts are fixed in a mould, the raw material of the cylinder base, namely pouring liquid after being cooled can form matched structures corresponding to the bulges or pits, and the matched structures can be closely matched with the bulges or pits of the inserts to effectively prevent the shifting and offset of the inserts. The insert system can be used as the accessory of the split type cylinder base of the refrigerator compressor.
Description
Technical field
The utility model relates to a kind of accessory of compressor for refrigeration, the inserter system of the split type cylinder seat of particularly a kind of compressor for refrigeration.
Background technique
An important consumption part in the compressor for refrigeration is exactly a cylinder seat.Cylinder seat has a casing bore and rotary shaft hole, supplies piston and rotating shaft high-speed motion, rotation back and forth respectively.Owing to often need bear such friction, so the inwall of casing bore and rotary shaft hole all needs resistance to compression, wear-resisting.Traditional compressor for refrigeration cylinder seat is the integral type cylinder seat, and promptly it is that cast inblock forms, and in order to let said inwall have the performance of anti-pressure and abrasion-proof, its casting material adopts cast iron.But so, will make the quality of cylinder seat become big, cost of production also improves.The split type cylinder seat of a kind of compressor for refrigeration is arranged now; Adopt split type design concept, be about to all/the loss face of the cylinder seat of part replaces to inserter (mainly being), forms the inserter system; So only need each part of said inserter system is made with high-abrasive material; The cylinder seat body can adopt cheap material (like aluminum alloy) to cast, and is so not only whole light, and reduced cost of production.But; Owing to adopted split type structure, inserter just must be nested with the cylinder seat body closely, but traditional coupling means of fixation is obviously impracticable; So; How realizing that through the structure that changes inserter itself and cylinder seat body closely cooperate, be difficult for the changing of the relative positions, distortion displacement, is a difficult problem that needs to be resolved hurrily in the industry.
The model utility content
The purpose of the utility model, be for provide a kind of can with the inserter system of the firmly chimeric split type cylinder seat of compressor for refrigeration of cylinder seat body.
The solution that the utility model solves its technical problem is:
The inserter system of the split type cylinder seat of compressor for refrigeration comprises several inserters, and each said inserter is provided with that at least one is raised or sunken.
As the further improvement of technique scheme, said inserter comprises cylinder sleeve, and the outer wall of said cylinder sleeve is provided with axial fin.
As the further improvement of technique scheme, said cylinder sleeve is provided with semicircular cylinder bore wall, and it connects with axial fin.
As the further improvement of technique scheme, said cylinder bore wall all has two with axial fin, lays respectively at the upper and lower of cylinder sleeve, said cylinder sleeve be about symplex structure.
As the further improvement of technique scheme, said cylinder sleeve is an iron member.
As the further improvement of technique scheme, said inserter comprises the rotating shaft cover, and the outer wall of said rotating shaft cover is provided with at least one radially shaft shoulder.
As the further improvement of technique scheme, the said radially shaft shoulder has a plurality of, along the central shaft radiation profiles of rotating shaft cover.
As the further improvement of technique scheme, the said radially shaft shoulder is provided with step.
As the further improvement of technique scheme, said rotating shaft cover is iron member.
The beneficial effect of the utility model is: the utility model is raised or sunken through on inserter, being provided with at least one; Make when producing split type cylinder seat; In case inserter fixes the position in mould; The raw material potting syrup of cylinder seat can form after cooling and said raised or sunken pairing matching structure, and said matching structure can closely cooperate with the convex/concave of inserter, has stoped the displacement changing of the relative positions of inserter effectively.
In addition; Inserter system in the utility model includes cylinder sleeve and rotating shaft cover; And, make the degrees of freedom of cylinder sleeve and rotating shaft cover obtain limiting, thereby reach the purpose of assurance positional accuracy through the axial fin and the shaft shoulder radially are set on cylinder sleeve and rotating shaft cover.
The utility model can be used as the accessory of the split type cylinder seat of compressor for refrigeration.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is that the axle of the cylinder sleeve in the utility model is surveyed schematic representation;
Fig. 2 is that the axle of the rotating shaft cover in the utility model is surveyed schematic representation.
Embodiment
With reference to Fig. 1～Fig. 2, the inserter system of the split type cylinder seat of compressor for refrigeration comprises several inserters, and each said inserter is provided with that at least one is raised or sunken.
Further as preferred embodiment, said inserter comprises cylinder sleeve 1, and the outer wall of said cylinder sleeve 1 is provided with axial fin 11.
Further as preferred embodiment, said cylinder sleeve 1 is provided with semicircular cylinder bore wall 12, and it connects with axial fin 11.
Further as preferred embodiment, said cylinder bore wall 12 all has two with axial fin 11, lays respectively at the upper and lower of cylinder sleeve 1, said cylinder sleeve 1 be about symplex structure.
Further as preferred embodiment, said cylinder sleeve 1 is an iron member.
Further as preferred embodiment, said inserter comprises rotating shaft cover 2, and the outer wall of said rotating shaft cover 2 is provided with at least one radially shaft shoulder 21.
Further as preferred embodiment, the said radially shaft shoulder 21 has a plurality of, along the central shaft radiation profiles of rotating shaft cover 2.
Further as preferred embodiment, the said radially shaft shoulder 21 is provided with step.
Further as preferred embodiment, said rotating shaft cover 2 is an iron member.
The part that cylinder sleeve 1 and rotating shaft cover 2 are inlayed when considering following process at the beginning of design may be out of shape and take place problems such as displacement; Therefore increased the structure of shaft shoulder face radially and axial many ribs (be the end face of said cylinder bore wall 12, axially the fin 11 and the shaft shoulder 21 radially); The advantage of this structure is to limit the degrees of freedom of inserter in split type cylinder seat; It can be subjected to displacement and be out of shape when stressed, guarantee element precision.And cylinder sleeve alveolus 1 last month partly adopts symplex structure also to design for the ease of guaranteeing machining accuracy.
In addition, preferably the inserter system comprises by cylinder sleeve 1 and rotating shaft cover 2 here, if but other are the technological scheme of the wear-resisting inserter in part through replacement loss face, also belong to the variant that is equal to of the utility model.
More than be that preferred embodiments to the utility model specifies; But the invention is not limited to said embodiment; Those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
