Abstract
The utility model provides a compressor mounting/fixing bushing. The compressor mounting/fixing bushing comprises cylindrical sections, flangings and an opening; the cylindrical sections include a first cylindrical section and a second cylindrical section, and the inner diameters of the first cylindrical section and the second cylindrical section are tapered; the flangings are arranged at the end portions of the cylindrical sections and in circular-arc transition with the cylindrical sections; the opening penetrates through the cylindrical sections and the flangings of the bushing. The structure of the compressor mounting/fixing bushing is capable of plugging the fit clearance between a compressor and a support, and the support is enabled to generate transverse frictional force and the propagation of stress induced pressure under the pull of a compressor lifting lug when the compressor runs is reduced, and therefore, the problems of breakage and deformation of the lifting lug are solved. Besides, the tapered inner diameter design and the opening design of the bushing are convenient for the mounting of the bushing so that the bushing is in interference fit with the compressor. The fit problem of the compressor and the support is effectively solved, and the compressor mounting/fixing bushing is convenient for the operating personnel to mount the compressor and also capable of effectively solving the fit clearance problem of the compressor.
Description
Technical field
The utility model relates to automobile accessory technical field, is specifically related to a kind of compressor fixed hub is installed.
Background technology
Compressor and support assembling mode have multiple: no matter axle dress, dish dress, straight dress etc., but which type of mode, fit system is generally three kinds of free-running fit, transition fit and interference fit, in order to produce the comfort feature of assembling, generally all adopts free-running fit.
Analyzing by the compressor damaged components of feeding back on market, is the fracture of compressor hanger, hanger distortion, bolt distortion etc. about coordinating the damage existing.The damaged situation of compressor on automobile is analyzed, and the compressor under different horsepower is damaged different, and general high-powered engine compressor damage rate is larger, and its working environment is poor.
When the compressor of design is installed at present, general bolt, spring shim, the nut of adopting installed.The cooperation of this compressor and support is free-running fit, and the installation dimension of Normal squeezing machine is 83.3 ± 0.1, and the installation dimension of support is 83(0 ,-0.3).This technical scheme convenient operation personnel install compressor, but the gap existing is apparent.Operating personal judges that compressor is that spring shim is tied with the installing condition that coordinates of support, and the effect of spring shim is to antagonistic force of nut after nut screwing clamping, increase the friction force between bolts and nuts, can not solve the tolerance clearance problem between compressor and support.
Utility model content
For problems such as the compressor hanger fracture that solves tolerance clearance problem between compressor and support and cause because of tolerance clearance, hanger deformation failure, bolt distortion, the purpose of this utility model provides a kind of new type compressor that fixed hub is installed.
Concrete technical scheme of the present utility model is as follows:
A kind of compressor is installed fixed hub, comprises column section, flange and opening,
Described column section comprises the first column section and the second column section, and the internal diameter of this first column section and the second column section is gradual change type internal diameter;
Described flange is arranged at the end of described column section, and with described column section arc transition;
Described opening runs through column section and the flange of described lining.
Preferably, the direction of described opening is parallel to the central axis of described lining.
Preferably, the wall thickness uniformity of described column section and flange.
Preferably, described the first column section internal diameter is greater than the internal diameter of described the second column section, and described flange is arranged at the end of described the first column section.
Preferably, the difference in internal diameters of described the first column section and described the second column section is less than 2mm.
Preferably, the diameter of described opening is less than 1.5mm.
Preferably, the material of described lining is Q235A.
The beneficial effects of the utility model are as follows:
The bush structure that the utility model provides can be filled up the tolerance clearance of compressor and support, makes support produce side-friction, while reducing compressor operation, stressed by compressor hanger pressure transmission situation, thereby solves the problem of hanger fracture, distortion.In addition, the gradual change internal diameter design of this lining and opening design, be convenient to the installation of lining, and the cooperation that makes lining and compressor is interference fit.Efficiently solve the matching problem of compressor and support, handled easily personnel install compressor, and actv. solves the tolerance clearance problem of its existence again, reduce the fault rate of market compressor, improve air conditioner refrigeration effect.

Fig. 2 the utility model compressor is installed fixed hub cutaway view;
Fig. 3 the utility model compressor is installed fixed hub birds-eye view.
In figure, Reference numeral is as follows:
Flange 1, column section 2, opening 3, the first column section 21, the second column sections 22.
Detailed description of the invention
Introduce in detail the utility model below in conjunction with accompanying drawing and detailed description of the invention thereof, illustrated by having the extension of number, position, relation and size of the assembly that forms preferred embodiment in accompanying drawing, read and understand instruction of the present utility model afterwards relevant change belong to industry technical ability.In addition, reading and understanding after instruction of the present utility model, coordinate the accurate dimension of specific strength, weight, intensity and similar requirement and the change of dimension scale also to belong to general knowledge known in this field.
As shown in Figure 1, a kind of compressor is installed fixed hub, comprises column section 2, flange 1 and opening 3.
As shown in Figure 2, described column section 2 comprises the first column section 21 and the second column section 22, and the internal diameter of this first column section 21 and the second column section 22 is gradual change type internal diameter, and described the first column 21 internal diameters are greater than the internal diameter of described the second column section 22; The installation of lining is convenient in this gradual change internal diameter design, and the cooperation that makes lining and compressor is interference fit.In a preferred version, the difference in internal diameters of described the first column section and described the second column section is less than 2mm.
As shown in Figure 2, described flange 1 is arranged at the end of described the first column section 21, and with described the first column section 21 arc transition, the wall thickness uniformity of described column 2 and flange 1.This design can make whole lining stressed evenly, and produces very strong side-friction.
As shown in Figure 3, described opening 3 runs through column section 2 and the flange 1 of described lining, and its direction is parallel to the central axis of described lining; Preferably, the diameter of described opening is less than 1.5mm.This opening design, is convenient to the installation of lining.
When installation, after fixing urgent compressor bolt, lining is filled up the gap of compressor and support, produce the side-friction with support simultaneously, stressing conditions in the time that compressor operation is worked, the vibration that compressor operation produces, mainly by the friction force of lining, is delivered to support.
The above is only preferred implementation of the present utility model, it is to be noted, these embodiment are only not used in restriction scope of the present utility model for the utility model is described, and, after having read content of the present utility model, relevant technical staff in the field can make various changes or amendment to the utility model, and these equivalent form of values fall into the application's appended claims limited range equally.
