Background

The refrigeration compressor is the core and heart of the refrigeration system. The capacity and characteristics of the compressor machine determine the capacity and characteristics of the refrigeration system. In a sense, the design and matching of the refrigeration system is to embody the capacity of the compressor. Therefore, the refrigeration industry of all countries in the world has no great energy to be put into the research of the refrigeration compressor, and new research directions and research results are continuously generated. The technology and performance levels of compressors are changing day by day. The variety of compressors is many, and the refrigeration compressors can be divided into fixed displacement compressors and variable displacement compressors according to different working principles.

The effect of the spacing collar on the existing mobile refrigeration compressor is mainly used in cooperation with a crankshaft retainer ring for limiting the position of a crankshaft in a mobile refrigeration compressor core and further limiting the position of the core, but the traditional spacing collar is still in an open state when being installed in the crankshaft retainer ring, so that the stability is not good enough, and therefore improvement is needed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a remove spacing collar for refrigeration compressor to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a remove spacing collar for compressor, is including removing compressor's inferior valve, bent axle retaining ring and spacing collar body, the welding of bent axle retaining ring is in the bottom of the inside of inferior valve, the annular has been seted up on the inner wall of bent axle retaining ring, the necking down groove has been seted up to the side of spacing collar body, the position that corresponds the annular groove on the outer wall of spacing collar body is provided with the snap ring, the snap ring card of spacing collar body is gone into in the annular in the bent axle retaining ring.

As a further aspect of the present invention: the bottom end of the crankshaft retainer ring is welded at the bottom end of the inner part of the lower shell.

As a further aspect of the present invention: the inside of inferior valve sets up the core, be provided with the bent axle in the core, the bottom of bent axle stretches into this internally of spacing collar.

Compared with the prior art, the beneficial effects of the utility model are that:

1. set up the groove of necking down through the side at the spacing collar body, set up the snap ring again on the outer wall of spacing collar body, the position that corresponds the snap ring on the inner wall of bent axle retaining ring sets up the annular, when installing the spacing collar body inside the bent axle retaining ring, the snap ring can block into the annular that corresponds with it, make spacing collar body installation back be closed form setting, make this spacing collar body outside tension compare in the open mode of old spacing collar bigger, it is just more firm in installing the bent axle retaining ring, be more difficult for droing, and simultaneously, the spacing collar body sets up outside the bent axle, can restrict the crankshaft position in the removal compressor core, and then can play the position of restriction core, and simultaneously, can also provide the cushioning effect for bent axle and core.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, in an embodiment of the present invention, a limiting ring for a mobile refrigeration compressor includes a lower shell 1 of the mobile refrigeration compressor, a crankshaft retainer ring 2 and a limiting ring body 3, the crankshaft retainer ring 2 is welded at the bottom end of the inner part of the lower shell 1, an annular groove 6 is formed on the inner wall of the crankshaft retainer ring 2, a necking groove 8 is formed on the side surface of the limiting ring body 3, a snap ring 7 is arranged on the outer wall of the limiting ring body 3 at a position corresponding to the annular groove 6, and the snap ring 7 of the limiting ring body 3 is clamped into the annular groove 6 in the crankshaft retainer ring 2; the bottom end of the crankshaft retainer ring 2 is welded at the bottom end of the interior of the lower shell 1; a machine core 4 is arranged in the lower shell 1, a crankshaft 5 is arranged in the machine core 4, and the bottom end of the crankshaft 5 extends into the limiting ring body 3; set up the groove of necking down 8 through the side at spacing collar body 3, set up snap ring 7 on the outer wall of spacing collar body 3 again, the position that corresponds snap ring 7 on the inner wall of bent axle retaining ring 2 sets up annular 6, when installing spacing collar body 3 inside bent axle retaining ring 2, snap ring 7 can block into in the annular 6 that corresponds with it, make spacing collar body 3 install the back and set up for closed form, make this spacing collar body 3 outside tension compare in the open mode of old spacing collar bigger, it is just more firm to install in bent axle retaining ring 2, be difficult for droing more.

The working principle is as follows: earlier the bottom of the inside of inferior valve 1 of crankshaft retainer ring 2 welding, then install the inside of crankshaft retainer ring 2 with spacing collar body 3, be that the outer snap ring 7 card of spacing collar body 3 is gone into in the annular 6 on the inner wall of crankshaft retainer ring 2, make the necking down groove 8 of spacing collar body 3 closed, thereby can increase the outside tension of spacing collar body 3, then stretch into spacing collar body 3 with the bottom of the bent axle 5 in core 4, make the bent axle 5 among the limiting collar body 3 restriction removal compressor, thereby can restrict the position of core 4, and provide cushioning effect for bent axle 5 and core 4.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
