Abstract
The utility model discloses a shaft coupler for connecting a high-speed shaft. The shaft coupler comprises a shaft rod with a shaft hole, wherein a key slot is arranged on the inner wall of the shaft hole along the axis direction; an annular flange is arranged on the outer wall of the shaft rod; the end face of the flange is leveled with the end face of the shaft rod; the flange is provided with a plurality of pin holes which are distributed along the annular shape; positioning bulges which are annularly distributed are arranged on the inner sides of the plurality of pin holes. The shaft coupler is novel in structural design; the pin holes, the annularly-distributed positioning bulges of the end face of the flange and the shaft coupler for connecting a transmission shaft are matched to use so that the positioning effect is good; the shaft coupler has good stability and vibration absorption performance in the working process and the requirements of actual work are met.
Description
technical field:
The utility model relates to coupling manufacturing technology, relates in particular to a kind of coupling connecting for high speed shaft.
background technique:
Coupling is mainly used in the connection between diaxon, and it also can be used for the connection between axle and reel, gear, belt wheel etc., and the main task of coupling is transmitting torque.
Joining coupling between current high speed shaft and other axles, there is defect in structural design, mainly that high speed shaft is applied in clockwise and anticlockwise and changes many, start occasion frequently, therefore during driving torque due to structure coupling less stable in working procedure after connection, bumper and absorbing shock performance does not reach requirement, and impact is normally worked.
model utility content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of coupling connecting for high speed shaft, and reasonable in design can be good at guaranteeing connecting between high speed shaft and other transmission shafts, and the gentle write-downs of stability shock stability is good.
The technical solution of the utility model is as follows:
The coupling connecting for high speed shaft, comprise the axostylus axostyle with axis hole, the inwall of axis hole is provided with keyway along axial direction, it is characterized in that: the outer wall of described axostylus axostyle is provided with annular flange, the end face of flange is concordant with the end face of axostylus axostyle, flange is provided with several pin-and-holes that prolong annular spread, and several pin-and-hole inner sides are provided with the positioning convex of annular spread.
The described coupling connecting for high speed shaft, is characterized in that: several described pin-and-holes are cone shape hole, and pin-and-hole reduces to the other end aperture gradually from end face.
The described coupling connecting for high speed shaft, is characterized in that: described positioning convex can be whole annulus or arc piece spaced apart, and the end surface thickness of positioning convex from end to flange increases gradually.
The utility model has the advantages that:
The utility model structural design is novel, the positioning convex of annular spread and the coupling of biography propeller shaft couplings by pin-and-hole and flange end face are used in combination, good positioning effect, stability and damping performance are good in the course of the work, have met the demand of real work.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
The coupling connecting for high speed shaft, comprise the axostylus axostyle 1 with axis hole 2, the inwall of axis hole 2 is provided with keyway 3 along axial direction, the outer wall of axostylus axostyle 1 is provided with annular flange 4, the end face of flange 4 is concordant with the end face of axostylus axostyle 1, flange 4 is provided with several pin-and-holes 5 that prolong annular spread, and several pin-and-hole 5 inner sides are provided with the positioning convex 6 of annular spread.
Several pin-and-holes 5 are cone shape hole, and pin-and-hole reduces to the other end aperture gradually from end face.
Positioning convex 6 can be whole annulus or arc piece spaced apart, and the end surface thickness of positioning convex from end to flange increases gradually.
