Abstract
The utility model discloses an overload protection mechanism of a compressor. The overload protection mechanism uses the flat key connection between a wheel hub and a main shaft of the compressor. A flat key base layer is made of metallic materials, and an outer layer is coated with non-metal materials with certain hardness and elasticity. The advantages of simple structure, easy fabrication, simple manufacturing process and low cost are satisfied by using an external control type variable displacement compressor which is disclosed by the utility model and uses the technical scheme of the utility model. When the compressor is opened and closed, the overload protection mechanism has a buffer function and a requirement of reducing the noise.
Description
Technical field
The utility model relates to the overload of compressor protection mechanism, more particularly, relates to a kind of external control formula variable compressor overload protecting mechanism.
Background technique
Used for automobile air conditioning external control formula variable compressor is rotated by the belt pulley that belt drives compressor by motor, and belt pulley drives spindle operation by the spline on the wheel hub again, and compressor can be worked.Compressor turns round always during engine running, and this just requires compressor must have overload protecting mechanism, and when the compressor internal mechanism was killed, pulley energy and main shaft broke away from.Belt pulley and wheel hub broke away from when existing overload protecting mechanism all was overload.But this mechanism ubiquity complex structure, and the shortcoming that cost is high, and because wheel hub and main shaft adopt spline to be connected, and fit system is a Spielpassung makes that compressor noise when starting suddenly and shutting down is very big.
So just need a kind ofly can overcome complex structure, the overload of compressor protection mechanism of cost height and the shortcoming that noise is very big when compressor starts suddenly and shuts down.
The model utility content
The purpose of this utility model provides a kind of overload of compressor protection mechanism, especially a kind of external control formula variable compressor overload protecting mechanism.
According to the utility model; a kind of overload protecting mechanism is provided; described overload protecting mechanism adopts flat key to be connected between the wheel hub of compressor and main shaft, the flat key basic unit employing metallic material that described overload protecting mechanism adopts, and skin is coated with has certain degree of hardness and flexible nonmetallic material.
Adopted the technical solution of the utility model; adopt external control formula variable compressor overload protecting mechanism that the utility model disclosed satisfied simple in structure, easy to process, assembly technology is simple, cost is low and at compressor start and when closing overload protecting mechanism have buffer function, reduce the demand of noise.
Description of drawings
The above and other feature of the utility model, character and advantage will further describe below in conjunction with the accompanying drawings and embodiments, and identical in the accompanying drawings reference character is represented identical feature all the time, wherein,
Fig. 1 is the structural drawing according to a kind of external control formula variable compressor overload protecting mechanism of embodiment of the present utility model.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
With reference to figure 1, Fig. 1 shows a kind of structure of overload protecting mechanism.According to an embodiment of the present utility model, this overload protecting mechanism is an external control formula variable compressor overload protecting mechanism, and it adopts flat key to be connected between the wheel hub of compressor and main shaft; Flat key basic unit adopts metallic material, and skin is coated with has certain degree of hardness and flexible nonmetallic material.
As previously mentioned, the shortcoming of prior art is a complex structure, the shortcoming that cost is high, and because the Placement of wheel hub and main shaft is that spline is connected, and the fit system Spielpassung makes that compressor noise when starting suddenly and shutting down is very big.New overload protecting mechanism has then been avoided above-mentioned shortcoming owing to avoided between belt pulley and wheel hub, adding overload protecting mechanism, belt pulley with become more simple being connected of wheel hub, this has just reduced cost, simplifies the structure and assembly technology; Wheel hub is connected with main spindle multiple spline and changes to after flat key connects, and processes convenient; Flat key is outer field to have when certain degree of hardness and flexible nonmetallic material can and be closed at compressor start and plays certain buffer function, reduces noise.
In sum, overload protecting mechanism of the present utility model is easy to process, simple in structure, assembly technology is simple, cost is low, and overload protecting mechanism has buffer function at compressor start and when closing, and reduces noise.
Though the technological scheme of this real model utility is illustrated in conjunction with preferred embodiment; but it should be appreciated by those skilled in the art; various modifications or change for the above embodiments are predictable; this should not be regarded as having exceeded protection domain of the present utility model; therefore; protection domain of the present utility model is not limited to above-mentioned specifically described embodiment, and should be the most wide in range scope that meets the inventive features that discloses in this place.
