Abstract
The utility model provides the positioning connecting device of a kind of stable sexual type and the high axle of reliability and gear, comprise driving gear, axis hole, gear shaft, draw-in groove, connection housing, lining, steel ball, spring, described driving gear offers axis hole, the upper end of described driving gear is provided with connection housing, the inside of described connection housing is provided with lining, described steel ball is by the inside of spring fitting at lining, described gear shaft offers draw-in groove, and described gear shaft to be coordinated with draw-in groove by steel ball through axis hole from top to bottom and driving gear is located by connecting.The utility model is by the effect of steel ball and spring, steel ball is snapped in together with connection gear is located by connecting with gear shaft by draw-in groove, not only make the installation of driving gear and gear shaft more simple and convenient, stability and reliability high, also avoid connected element when traditional large gear is in use subject to larger impact force and vibration force and to fluff situation about even losing efficacy.
Description
Technical field
The utility model relates to technical field of mechanical transmission, particularly relates to the positioning connecting device of a kind of axle and gear.
Background technique
In mechanical transmission structure, the gear shaft that driving gear generally uses axle to be located in gear supports, then adopt nut etc. to connect fastening piece and carry out compression axis, and pin nut in order to locking by locking plate, but in some main equipments, the moment of torsion of gear transmission and power are very large, gear and axle be subject to larger impact force and vibration force can fluff, even cause Joint failure, thus substantially reduce the working life of gear; And the positioning connecting device of most number axis and gear is all bulk metal material, and outer threaded structure, to be fixed in use on corresponding part, be easy in use loosen, reliability extreme difference, standard model is few again, and the producer being not suitable for particular/special requirement uses.
Summary of the invention
According to above technical problem, the utility model provides the positioning connecting device of a kind of stability and the high axle of reliability and gear, comprise driving gear, axis hole, gear shaft, it is characterized in that: also comprise draw-in groove, connect housing, lining, steel ball, spring, described driving gear offers axis hole, the upper end of described driving gear is provided with connection housing, the inside of described connection housing is provided with lining, described steel ball is by the inside of spring fitting at lining, described gear shaft offers draw-in groove, described gear shaft to be coordinated with draw-in groove by steel ball through axis hole from top to bottom and driving gear is located by connecting.
Described draw-in groove has N number of, N >=1, and N number of described draw-in groove is vertically distributed on gear shaft.
The beneficial effects of the utility model are: the utility model improves on the positioning connecting device of original axle and gear, namely steel ball is added in the inside of lining, by the effect of steel ball and spring, steel ball is snapped in together with connection gear is located by connecting with gear shaft by draw-in groove, not only make the installation of driving gear and gear shaft more simple and convenient, stability and reliability high, also avoid connected element when traditional large gear is in use subject to larger impact force and vibration force to fluff situation about even losing efficacy, thus extend the working life of positioning connecting device, and the structure of this connection set is simple, be beneficial to production, be applicable to the connection gear of different field and being located by connecting of gear shaft, using scope is extensive.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model.
Embodiment
According to Fig. 1, the utility model is further described:
As Fig. 1, driving gear-1, axis hole-2, gear shaft-3, draw-in groove-4, connection housing-5, lining-6, steel ball-7, spring-8.
Embodiment 1
The utility model comprises driving gear 1, axis hole 2, gear shaft 3, draw-in groove 4, connects housing 5, lining 6, steel ball 7, spring 8, axis hole 2 is offered in the central position of driving gear 1, gear shaft 3 offers draw-in groove 4, the upper end of driving gear 1 is for connecting housing 5, first steel ball 7 is arranged on the inside of lining 6 during installation by spring 8, then lining 6 is arranged on the inside connecting housing 5, finally gear shaft 3 is passed axis hole 2 from top to bottom, the top pressure making steel ball 7 be subject to spring 8 snaps in draw-in groove 4, completes gear shaft 3 and is located by connecting with driving gear 1.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
