Abstract
The utility model provides a tension sleeve, wherein the tension sleeve is capable of locking and fixing a shaft with a hub sleeved on the shaft conveniently and is reliable in connection and convenient to disassemble and install. The tension sleeve comprises an outer ring sleeve and an inner ring sleeve, the outer ring sleeve and the inner ring sleeve are both not closed in the circumferential direction. Two ends of the inner wall of the outer ring sleeve and two ends of the outer wall of the inner ring sleeve are both cone-shaped, two corresponding cone sleeves are arranged between the cones arranged at two ends of the outer ring sleeve and the cones arranged at two ends of the inner ring sleeve, and the two ring sleeves are same in conical degree and opposite in direction. At least one screw rod penetrates through one cone sleeve, and is in thread connection with another cone sleeve. When the screw rod is rotated, the screw rod is capable of driving the two cone sleeves to move relatively along the axial direction of the cone sleeves.
Description
Technical field
Present technique relates to a kind of expansion sleeve, mainly is used as the locking device of wheel hub and axle.
Background technique
Axle be sleeved on being locked of the wheel hubs such as belt pulley on the axle, flying wheel, the tradition key connecting, working life is short, waste is very large, be not easy to installing/dismounting, according to these characteristics, my company is reliable from installing, easy to use, cost saving is considered, produces this product.
Summary of the invention
The purpose of present technique provides a kind of easily expansion sleeve of can conveniently axle being fixed with the wheel hub locking on being sleeved on axle, be connected reliably, remove and install.
This expansion sleeve comprises coaxial exterior ring cap, inner ring sleeve, and exterior ring cap, inner ring sleeve all are circumferential inc ring sets; The inwall two ends of exterior ring cap, the outer wall two ends of inner ring sleeve are taper, are provided with two corresponding tapered sleeves between the taper at the taper at exterior ring cap two ends and inner ring sleeve two ends, and two tapered sleeve taperings are identical, opposite direction; Have at least a screw rod to pass a tapered sleeve, and be threaded connection with another tapered sleeve; When rotating screw bolt, can drive two tapered sleeves axially relatively moving along tapered sleeve by screw rod.
The beneficial effects of the utility model: need to be axle and wheel hub locking fixedly the time, on the inner ring sleeve suit axle, exterior ring cap is positioned at the endoporus of wheel hub.By turning screw rod, two tapered sleeves axially relatively moving and decreased distance along tapered sleeve, two tapered sleeves since with the taper at the outer wall two ends of the inwall two ends of exterior ring cap, inner ring sleeve to cooperating, so, tapered sleeve with regard to so that inner ring sleeve circumferentially shrink and clamp shaft, simultaneously tapered sleeve so that the circumferential spreading of exterior ring cap and tensioner at wheelboss inner hole.Certainly, the distance between the counter-rotation screw rod, two tapered sleeves increases gradually, and exterior ring cap, inner ring sleeve return to again reset condition under the elastic reaction of self, can unclamp.This expansion sleeve connects reliably, removes and installs conveniently, can be to axle and wheel hub injury.
Above-mentioned expansion sleeve has one and is parallel to the groove of ring set axis and forms circumferential inc ring set on exterior ring cap or the inner ring sleeve.
Above-mentioned expansion sleeve, described screw rod are 15-27, are distributed on the week of tapered sleeve upwards.
Description of drawings
Fig. 1 is that expansion sleeve is at the schematic diagram of the state of use.
Fig. 2 is the side view of inner ring sleeve.
Fig. 3 is the side view of exterior ring cap.
Fig. 4 is the side view of left tapered sleeve.
Embodiment
Referring to expansion sleeve shown in Figure 1, exterior ring cap 1, inner ring sleeve 2, left tapered sleeve 3, right tapered sleeve 5 all are coaxial settings.Respectively having one on exterior ring cap and the inner ring sleeve is parallel to the groove 4 of ring set axis and forms circumferential inc elasticity ring set.The inwall two ends of exterior ring cap, the outer wall two ends of inner ring sleeve are taper.Between the taper of the taper of exterior ring cap left end and inner ring sleeve left end, left tapered sleeve 5 is set, between the taper of the taper of exterior ring cap right-hand member and inner ring sleeve right-hand member, right tapered sleeve 5 is set.The tapering of left tapered sleeve 3, right tapered sleeve 5 is identical, opposite direction.27 screw rods 7 pass 27 through holes 6 on the left tapered sleeve 3, and with right tapered sleeve on 27 tapped holes be threaded connection; The week that 27 screw rods 7 are distributed on left tapered sleeve upwards.When rotating screw bolt, by screw rod can drive left tapered sleeve 3, right tapered sleeve 5 axially relatively moves along left tapered sleeve.On the inner ring sleeve suit axle 8, exterior ring cap is positioned at the endoporus of wheel hub 9.
