Abstract
The utility model discloses a positioning structure of an eccentric wheel, which comprises a rotary shaft and an eccentric wheel which are arranged on a bearing. The positioning structure of the eccentric wheel is characterized in that a positioning boss is arranged between the eccentric wheel and the bearing. With the adoption of the positioning structure of the eccentric wheel, a gap between the eccentric wheel and the bearing is reduced, so that the installation is facilitated, the positioning structure is convenient and reliable, the structure is simple and practical, and the positioning structure has good popularization value.
Description
Technical field
The utility model relates to the Compressor Technology field, relates to a kind of eccentric wheel position structure of compressor in particular.
Background technique
Air compressor through blade or rotor rotatablely move or the to-and-fro motion of piston with air compression in gas tank, and exhaust when needed.The eccentric wheel of traditional oilless compressor is socketed in the rotating shaft, and the eccentric wheel operated by rotary motion is in the outside of bearing, because the gap of eccentric wheel and bearing is bigger, and position, inconvenient school during installation.
The model utility content
The purpose of the utility model be exactly provide for the deficiency that solves existing technology a kind of not only favourable with in installation, convenient and reliable, and simple and practical eccentric wheel position structure.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of eccentric wheel position structure, comprise rotating shaft, eccentric wheel on the bearing that is installed on compressor, and it is characterized in that, be provided with positioning boss between said eccentric wheel and the bearing.
As further specifying of such scheme: in rotating shaft, eccentric positioning boss is close to bearing surface to said eccentric wheel through screw.
Said positioning boss is the boss that is arranged on the eccentric wheel end face.
Said eccentric side is stepped.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model is employed in the positioning boss that eccentric end face setting cooperates with bearing, and the gap of eccentric wheel and bearing is reduced, favourable with in installation, convenient and reliable, simple and practical.

Fig. 1 is the structural representation of the utility model.
Description of reference numerals: 1, bearing 2, rotating shaft 3, eccentric wheel 4, positioning boss 5, screw
Embodiment
As shown in Figure 1, a kind of eccentric wheel position structure of the utility model comprises rotating shaft 2, eccentric wheel 3 on the bearing 1 that is installed on compressor, is provided with positioning boss 4 between eccentric wheel 3 and the bearing 1.In the present embodiment, the side of eccentric wheel 3 is stepped, and positioning boss 4 is for being arranged on the boss of eccentric wheel end face, and eccentric wheel 3 is fixed in the rotating shaft 2 through screw 5, and eccentric positioning boss is close to bearing surface.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement, these all belong to the protection domain of the utility model.
Claims (4)
