nullThe utility model discloses the balance flexible axle of a kind of Universal drive，Including sleeve pipe，Interior axle it is provided with in described sleeve pipe，The two ends of interior axle connect jointing，Interior axle is formed by connecting by multiple connecting shafts head and the tail，One end of each connecting shaft is equipped with link slot，The other end is provided with the connection tongue matched with link slot，End, link slot place and connection tongue are equipped with corresponding through hole，Connect in through hole and have bearing pin，The connecting shaft of link slot both sides is provided with groove，The connecting shaft connecting tongue both sides is provided with the lug corresponding with groove，The balance flexible axle of this Universal drive is in transmission process，Lug and groove fit improve the contact area between connecting shaft，Reduce link slot and be connected the shearing that tongue acts on bearing pin，Extend the service life of bearing pin，Simultaneously，On internal surface of casing, the ball in mounting groove rotates along with interior axle and rotates，Thus reduce interior frictional force between axle and sleeve pipe，Thus effectively reduce the power transmission loss of flexible axle.
Description
Technical field
This utility model relates to mechanical driving device technical field, the balance flexible axle of a kind of Universal drive.
Background technology
In mechanical transmission mechanism, there is many needs to possess connection two ends rotary shaft while rotating, have significantly
Axially displacement and the universal transmission mechanism of axial runout, connected by bearing pin between the connecting shaft of existing flexible axle, and connecting shaft exists
In transmission process, the shearing produced between connecting shaft can accelerate the damage of bearing pin, the most traditional flexible axle sleeve pipe and interior axle it
Between rub excessive so that soft axle transmission loss is big, to this end, it is proposed that the balance flexible axle of a kind of Universal drive.
Utility model content
The purpose of this utility model is to provide the balance flexible axle of a kind of Universal drive, to solve to carry in above-mentioned background technology
The problem gone out.
For achieving the above object, this utility model following technical scheme of offer: the balance flexible axle of a kind of Universal drive, including
Sleeve pipe, is provided with interior axle in described sleeve pipe, the two ends of interior axle connect jointing, and described interior axle is connected by multiple connecting shafts head and the tail
Forming, one end of each connecting shaft is equipped with link slot, and the other end is provided with the connection tongue matched with link slot, at link slot
It is equipped with corresponding through hole on end, place and connection tongue, and connection has bearing pin in through hole, described link slot both sides
Connecting shaft is provided with groove, and the connecting shaft connecting tongue both sides is provided with the lug corresponding with groove.
The inner surface of described sleeve pipe is provided with mounting groove, is provided with short axle in mounting groove, and on short axle, string has ball, and ball
Outer surface contact with interior axle surface.
Preferably, described groove is sector structure, and the front end of lug is semicircular structure, and the front end of lug is semicircle
Structure is in close contact with groove.
Preferably, the ball on described short axle is no less than three.
Preferably, described bushing outer surface is provided with heat radiation projection.
Compared with prior art, the beneficial effects of the utility model are: the balance flexible axle of this Universal drive is at transmission process
In, lug and groove fit improve the contact area between connecting shaft, reduce link slot and act on cutting on bearing pin with being connected tongue
Power, extends the service life of bearing pin, and meanwhile, on internal surface of casing, the ball in mounting groove rotates along with interior axle and rotates, thus
Reduce interior frictional force between axle and sleeve pipe, thus effectively reduce the power transmission loss of flexible axle.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is connecting structure for connecting shaft schematic diagram of the present utility model.
In figure: 1 sleeve pipe, axle in 2,3 jointings, 4 connecting shafts, 5 link slots, 6 connect tongues, 7 bearing pins, 8 grooves, 9 lugs,
10 mounting grooves, 11 short axles, 12 balls.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-2, a kind of technical scheme of this utility model offer: the balance flexible axle of a kind of Universal drive, including set
Pipe 1, sleeve pipe 1 outer surface is provided with heat radiation projection, is provided with interior axle 2 in sleeve pipe 1, and the two ends of interior axle 2 connect jointing 3, interior
Axle 2 is formed by connecting by multiple connecting shafts 4 head and the tail, and one end of each connecting shaft 4 is equipped with link slot 5, and the other end is provided with and connects
The connection tongue 6 that access slot 5 matches, is equipped with corresponding through hole on end, link slot 5 place and connection tongue 6, and logical
Connecting in hole has bearing pin 7, the connecting shaft 4 of link slot 5 both sides to be provided with groove 8, connect the connecting shaft 4 of tongue 6 both sides be provided with
The lug 9 that groove 8 is corresponding, groove 8 is sector structure, and the front end of lug 9 is semicircular structure, and the front end of lug 9 half
Circular configuration is in close contact with groove 8, and the inner surface of sleeve pipe 1 is provided with mounting groove 10, is provided with short axle 11 in mounting groove 10, short
On axle 11, string has ball 12, and the outer surface of ball 12 contacts with interior axle 2 surface, and the ball 12 on short axle 11 is no less than three,
The balance flexible axle of this Universal drive is in transmission process, and lug 9 coordinates the contact area improved between connecting shaft 4 with groove 8, subtracts
Little link slot 5 acts on the shearing on bearing pin 7 with being connected tongue 6, extends the service life of bearing pin 7, meanwhile, on sleeve pipe 1 inner surface
Ball 12 in mounting groove 10 rotates along with interior axle 2 and rotates, thus reduces interior frictional force between axle 2 and sleeve pipe 1, thus has
