Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of compressor.
Background technique
Compressor refers to a kind of driven fluid machinery low-pressure gas being promoted to pressurized gas, is the heart of refrigeration system.It sucks the refrigerant gas of low-temp low-pressure from sucking pipe, after driving piston to compress it by motor rotation, the refrigerant gas of High Temperature High Pressure is discharged to outlet pipe, for refrigeration cycle provides power, thus realize the refrigeration cycle of compression → condensation (heat release) → expand → evaporate (heat absorption).
In field of mechanical technique, the driving mode of classic screw air compressor adopts coupling to drive.There is following shortcoming in the structure of above-mentioned driving mode: first, motor drives the host work of compressor by coupling, cause machine shape size larger, the angle developed from compressor complete machine to trend toward miniaturization is considered, owing to including the bearing for fixed electrical machinery in compressor, obvious this compressor arrangement is the requirement not meeting era development, in final assembly, the assembly process of compressor exist complicated loaded down with trivial details, not easily assemble, make the technical problems such as the cost increase of compressor.
Summary of the invention
The utility model is the problems referred to above existed for existing technology, and provide a kind of compressor, technical problem to be solved in the utility model is: the assembling and the dismounting operation that how to simplify compressor.
The purpose of this utility model realizes by following technical proposal:
A kind of compressor, described compressor comprises fuselage and motor, and rotate in described motor and be provided with rotor, described rotor offers mounting hole vertically; Rotate in described fuselage and be provided with male rotor, one end of described male rotor is inserted in described mounting hole and both are fixedly connected with.
Its working principle is as follows: one end of male rotor, when assembling, directly can be inserted in the mounting hole of rotor, male rotor is fixedly connected with rotor by this compressor.And compressor of the prior art is when assembling, needs first male rotor to be connected with coupling, being connected with rotor by coupling.Under contrast, the assembling of this compressor, without the need to using coupling, both reduced assembly cost, in turn simplify assembly process, had above-mentioned advantage equally when dismantling; As keeped in repair compressor in later stage using process, then same mounting or dismounting are all very convenient.
In above-mentioned a kind of compressor, preferably, described male rotor comprises body and extension part, and described body rotates and is arranged in fuselage, and the inner of described extension part is connected with described body, and the outer end of described extension part is plugged in described mounting hole.
In above-mentioned a kind of compressor, preferably, a fixed hole is offered in described rotor, a tapered sleeve is provided with in described fixed hole, described mounting hole is offered in described tapered sleeve, described mounting hole is tapered, and the heavy caliber end of this mounting hole is towards described fuselage, and described extension part has the inclined-plane matched with described mounting hole inwall near self outer end place.Play the effect facilitating and assemble between male rotor and rotor.
In above-mentioned a kind of compressor, preferably, the sidewall of described extension part offers keyway, is provided with flat key in described keyway, and the both sides of described flat key recline mutually with the inwall of described tapered sleeve and the bottom land of keyway respectively.The connection of male rotor and rotor is played more firmly act on.
In above-mentioned a kind of compressor, preferably, described compressor also comprises dismounting pressing plate, screw and be opened in the tapped hole one at described extension part outer end place, described dismounting pressing plate comprises plate body, joint and tapped hole two, described plate body and joint are connected as a single entity, described tapped hole two runs through described plate body and joint simultaneously, described joint passes the small-caliber end of described mounting hole and is plugged in this mounting hole, the inner side of described plate body reclines mutually with the end face of the small-caliber end of described mounting hole, the head of described screw is resisted against on the outer side surface of described plate body, the bar portion of described screw is threaded with described tapped hole one through described tapped hole two, the internal diameter of described tapped hole two is greater than the external diameter in described screw rod portion.When dismantling male rotor, can adopt the screw that an external diameter matches with tapped hole two, turn screw head makes the afterbody of screw rely on the outer end of male rotor, continues this screw of turn, then male rotor can be ejected, for convenience detach.
Compared with prior art, the utility model has the following advantages:
The assembling of this compressor, without the need to using coupling, both reduced assembly cost, in turn simplify assembly process, had above-mentioned advantage equally when dismantling; As keeped in repair compressor in later stage using process, then same mounting or dismounting are all very convenient.
