Abstract
An axial securing means for impeller for parts on shaft, the means of fixation solving existing parts on shaft need carry out destructiveness processing to axle, affects the technical problem of axle intensity.The utility model is made up of tapered sleeve and wedging bolt, tapered sleeve is sleeved between axle and parts on shaft, the diameter of bore of tapered sleeve is identical with the diameter of axle, the male cone (strobilus masculinus) of tapered sleeve coordinates with the inner conical surface of parts on shaft, on tapered sleeve, the center line that is parallel to axle at least processes the uniform mounting hole of 3 circumferences, be processed with tapped hole on parts on shaft, corresponding to mounting hole, wedging bolt is connected with tapped hole through mounting hole.When the utility model is fixed parts on shaft, do not need to carry out any processing to axle, thus avoid the structure destroying axle, improve the working life of axle.
Description
Technical field
The utility model relates to a kind of axial securing means for impeller of parts on shaft.
Background technique
Usually, the axial restraint of parts on shaft to be coordinated by key or locating stud realizes, and needs on axle, process keyway or hole.Due to the stressed comparatively large of axle and load alternation, add the intensity that trade union affects axle so damaging.Therefore, when the axial restraint employing key cooperation of parts on shaft or locating stud, need the diameter adding macro-axis to carry out compensation intensity, the weight of axle will be increased like this, improve the cost of product.
Model utility content
The purpose of this utility model is intended to the shortcoming overcoming prior art, provides a kind of axial securing means for impeller of parts on shaft, and the axial restraint mode solving existing parts on shaft need carry out destructiveness processing to axle, affects the technical problem of axle intensity.
The utility model is achieved through the following technical solutions:
A kind of axial securing means for impeller of parts on shaft, it is characterized in that: the axial securing means for impeller of described parts on shaft is made up of tapered sleeve and wedging bolt, described tapered sleeve is sleeved between axle and parts on shaft, the diameter of bore of described tapered sleeve is identical with the diameter of described axle, the male cone (strobilus masculinus) of described tapered sleeve coordinates with the inner conical surface of described parts on shaft, on described tapered sleeve, the center line being parallel to axle at least processes the uniform mounting hole of 3 circumferences, on described parts on shaft, tapped hole is processed with corresponding to described mounting hole, described wedging bolt is threaded with described tapped hole through described mounting hole.
Further, the conical surface angle α of described tapered sleeve is less than 60 °.
Further, the large end of described male cone (strobilus masculinus) and the head of described wedging bolt are in same one end.
The utility model compared with prior art, owing to being set with tapered sleeve between axle and parts on shaft, and the mounting hole of tapered sleeve is passed with wedging bolt, be connected with the tapped hole of parts on shaft, during peaceful tight wedging bolt, by the conical surface of parts on shaft and tapered sleeve wedging, and then by the internal diameter of tapered sleeve and shaft compression, the axial restraint of parts on shaft will be achieved.When the utility model is fixed parts on shaft, do not need to carry out any processing to axle, thus avoid the structure destroying axle, the stress reducing axle is concentrated, and improves the working life of axle.
