Abstract
The utility model discloses a novel impeller bush, including the columniform cover body, overlap internal portion's cavity and be provided with a cylindricality cavity that runs through set body in inside, be provided with a plurality of teeth of a cogwheel on the outer peripheral surface of the cover body, the teeth of a cogwheel are evenly distributed on set body, the cylindricality cavity is provided with an inner chamfering with the junction of cover body upper surface, inner chamfering is slope chamfer or step chamfer, the lower part of the cover body is provided with the spacing ring of a stepped ramp type, the internal surface of cylindricality cavity perhaps is provided with a plurality of interior teeth of a cogwheel of evenly arranging for smooth surface. The utility model has the advantages of prior art's drawback, the reasonable novelty of structural design can be overcome to it.
Description
Technical field
The utility model relates to a kind of novel impeller lining, belongs to metal processing sectors.
Background technique
In impeller bush structure traditional at present design, single structure and these two kinds of structures of simple and easy assembly structure cannot adapt to the operating mode that becomes increasingly complex and Production requirement, single structure cannot provide large axial rigidity, car load is generally handling, and simple and easy assembly structure, can only provide unidirectional large axial rigidity, car load is handling slightly good; The noise that these two kinds of structures cannot avoid integral installation distribution structure to produce when contacting with each other, thus cause the result that life of product is low, handling is poor.
Model utility content
For the deficiency that prior art exists, technical problem to be solved in the utility model is, provide a kind of novel impeller lining, intensity is high, and contact is tight, long service life.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is, a kind of novel impeller lining, comprises columniform body, and body inner hollow is also provided with the cylindrical cavity that runs through body in inside; The external peripheral surface of described body is provided with some gear teeth, and the gear teeth are uniformly distributed on body; The joint of described cylindrical cavity and body upper surface is provided with an interior chamfering; Described interior chamfering is slope chamfering or step chamfering; The bottom of described body is provided with the limited ring of a stepped ramp type; The internal surface of described cylindrical cavity is smooth surface or the interior gear teeth being provided with some even arrangements; The top of the described gear teeth is provided with the chamfering of 42 degree; The height of described limited ring is 5-12MM.
Optimize, above-mentioned novel impeller lining, the described gear teeth are the rectangle gear teeth.
Optimize, above-mentioned novel impeller lining, the described gear teeth are the circular arc gear teeth.
Optimize, above-mentioned novel impeller lining, the middle part of the described gear teeth is provided with the groove of a rectangle.
Optimize, above-mentioned novel impeller lining, the angle of described slope chamfering is 38 degree.
Optimize, above-mentioned novel impeller lining, the height of described step chamfering is 1.5-2.2CM.
Optimize, above-mentioned novel impeller lining, is provided with the ring surface coaxial with cylindrical cavity that a segment length is 1.2-1.8CM above described step chamfering.
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design is novel.The design of the application arranges a cylindrical cavity in the inside of lining, reduces whole lining weight.In the joint of cylindrical cavity and lining, an interior chamfering is set, workpiece is conveniently had to enter bush inside, do not need to apply excessive pressure can assemble, easy to assembly, when interior chamfering is slope chamfering and angle is 38 degree, it reaches best assembling condition, very easily assembles, reduces to greatest extent and enter difficulty.When for step chamfering, when the height of step chamfering is 1.5-2.2Cm, its assembling is the simplest and easy.In order to reduce assembling difficulty further, improve closeness of contact, can arrange the ring surface coaxial with cylindrical cavity that a segment length is 1.2-1.8CM above step chamfering, such assembling pressure is minimum.

Embodiment
Technical characterstic of the present invention is set forth further below in conjunction with accompanying drawing and specific embodiment.
embodiment 1
The utility model is a kind of novel impeller lining, comprises columniform body, and body inner hollow is also provided with the cylindrical cavity that runs through body in inside; The external peripheral surface of described body is provided with some gear teeth, and the gear teeth are uniformly distributed on body; The joint of described cylindrical cavity and body upper surface is provided with an interior chamfering; Described interior chamfering is slope chamfering; The bottom of described body is provided with the limited ring of a stepped ramp type; The internal surface of described cylindrical cavity is smooth surface; The top of the described gear teeth is provided with the chamfering of 42 degree; The height of described limited ring is 5MM.The described gear teeth are the rectangle gear teeth.The angle of described slope chamfering is 38 degree.
embodiment 2
A kind of novel impeller lining of the utility model, is characterized in that: comprise columniform body, and body inner hollow is also provided with the cylindrical cavity that runs through body in inside; The external peripheral surface of described body is provided with some gear teeth, and the gear teeth are uniformly distributed on body; The joint of described cylindrical cavity and body upper surface is provided with an interior chamfering; Described interior chamfering is step chamfering; The bottom of described body is provided with the limited ring of a stepped ramp type; The internal surface of described cylindrical cavity is provided with the interior gear teeth of some even arrangements; The top of the described gear teeth is provided with the chamfering of 42 degree; The height of described limited ring is 12MM.
The height of described step chamfering is 1.5CM.The described gear teeth are the circular arc gear teeth.The middle part of the described gear teeth is provided with the groove of a rectangle.The ring surface coaxial with cylindrical cavity that a segment length is 1.2CM is provided with above described step chamfering.
