Abstract

The utility model relates to a torsion transmitting device. The torsion transmitting device comprises a driving gear and a driven gear. The torsion transmitting device is technically characterized in that a core body is arranged between the driving gear and the driven gear; traction ropes wind the surface of the core body; a rubber filler fills gaps of the traction ropes; the core body, the traction ropes and the rubber filler form an integrated body; the integrated body is placed into a rubber sleeve. The torsion transmitting device has the beneficial effects that the traction ropes wind the surface of the core body to avoid two defects that when one single core body serves as a torsion transmitting carrier, the core body is fractured easily and transmitted torsion is small if the core body is small, but if the core body is too big, the core body cannot be bended and is high in weight and cost although transmitted torsion is large; if one single traction rope is in use, the rope knots easily when being twisted and consequently the torsion cannot be transmitted. According to the device, torsion is converted to traction firstly, and then the traction is converted to torsion.

Description

A kind of torsion transmitting set

Technical field:

The utility model relates to torsion transmitting set.

Background technique:

At present, torsion transmitting set mainly contains universal joint for automobile, bicycle chain, various mechanical driving belt and various mechanical gear transmission device etc.The shortcoming that above torsion transmitting set exists: the one, transmission distance is short, and the 2nd, can only straight line (there is certain curve, the universal joint of using such as automobile, but curve is all very little) transmission.As installed remote (such as 100 meters or farther) and become curve form transmission torsion with above, implement just more difficult.Such as often de-chain of bicycle chain, impact is used function.

Summary of the invention:

Problem to be solved in the utility model be exactly provide for above deficiency a kind of can be at a distance and the torsion transmitting set of curve transmission.Its technological scheme is as follows:

It comprises driving gear and driven gear, its key technology is, between driving gear and driven gear, core body is installed, and is wound around tow rope in core surface, clogs rubber filling thing between the gap of tow rope, core body, tow rope, rubber filling thing form assemblying body, and assemblying body is inserted in rubber sleeve pipe.

Compared with prior art, the beneficial effect the utlity model has is:

1, be wound around tow rope in core surface, avoided following two drawbacks: 1. alone core body is made transmission torsion carrier, and core body is little, easily fracture, transmission torsion is also little, and core body is too large, and the torsion of transmission is larger, but can not be bending, and the too heavy cost of core body is also high simultaneously; 2. as alone tow rope, when torsion, easily tie a knot, can not transmit torsion.Utilize torsion to be changed to tractive force, tractive force is converted to torsion again.

2, the utility model both can remote transmission torsion, again can curve transmission torsion.

Brief description of the drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is that the utility model uses phase diagram.

Embodiment:

Referring to Fig. 1, the utility model comprises driving gear 1 and driven gear 8, its key technology is to fixedly mount core body 5 between driving gear 1 and driven gear 8, be wound around tow rope 7 on core body 5 surfaces, between the gap of tow rope 7, clog rubber filling thing 6, core body 5, tow rope 7, rubber filling thing 6 form ganoid flexible round bar shaped assemblying body, and assemblying body is inserted in rubber sleeve pipe 9.

Described core body 5 adopts steel wire or charcoal element etc. to have the material of obdurability and hardness.

Described tow rope 7 adopts steel wire or other textile rope.

Described core body 5 surfaces by many tow ropes 7 with clockwise or/and be counterclockwise wound around in the shape of a spiral.

Described rubber sleeve pipe 9 both ends opens, and seal ring 3 is set.

Described rubber sleeve pipe 9 two ends, below fixing device for installing 2, for fixing rubber sleeve pipe 9.

There is one deck lubricant oil 4 on described rubber filling thing 6 surfaces.

Working procedure of the present utility model is:

As Fig. 2, shown in Fig. 1, power source 10(is as the chain drum of bicycle) rotate along the direction of arrow (left), drive driving gear 1 to rotate along the direction of arrow (outwards), driving gear 1 drives core body 5 and the tow rope 7 in rubber sleeve pipe 9 to rotate along driving gear sense of rotation, form torsion and this torsion is passed to core body 5, also this torsion is passed to tow rope 7 simultaneously, the power that acts on tow rope 7 is tractive force, the direction of tractive force is along the surperficial tangent direction of core body 5, so tractive force is converted to again twisting force in core body 5 simultaneously and is transferred to the driven gear 8 of the other end, complete torsion transmitting procedure, can realize remote or curve transmission torsion.

Because the utility model both can remote transmission torsion, again can curve transmission torsion, so be specially adapted to bicycle and submersible pump, avoid motor to leak electricity in water, improve Safety performance.
