Accompanying drawing explanation
Fig. 1 is this utility model external structure schematic diagram.
Fig. 2 is this utility model structure sectional view.
Detailed description of the invention
See Fig. 1,2, a kind of motor output gear axis transmission structure, include motor shaft 1, gear 2 and output connecting shaft 5, there is on motor shaft 1 stripper loop 4 that one connects, the motor shaft 1 being positioned at stripper loop 4 side is provided with round platform portion 3, gear 2 is sleeved in round platform portion 3, and output connecting shaft 5 is sleeved on the motor shaft 1 being positioned at stripper loop 4 opposite side.
In this utility model, gear 2 and the output equal single injection-molded of connecting shaft 5.
The periphery in round platform portion 3 is provided with circumferentially positioned groove 8, and the inner headed face of gear 2 has the centring ring 9 embedded in circumferentially positioned groove 8 connected together.
The periphery of motor shaft 1 is provided with standstill face 6, and the inner headed face of output connecting shaft 5 is provided with the rotation prevention portion 7 adapted with standstill face 6.
Below in conjunction with accompanying drawing, this utility model is further described:
Gear 2 and output connecting shaft 5 are once injection moulding, simple in construction, production cost is low, it it is frictional connection between motor shaft 1 and gear 2, can relatively rotate between gear 2 and motor shaft 1, the connecting portion of motor shaft 1 and gear 2 is round table-like inclined-plane, it is able to ensure that the moment of friction needed for transmission, and, when starting moment or gearbox fault, in the case of gear 2 does not turns, motor can also rotate alone, can effectively prevent motor rotation blockage from burning out or break the teeth of gear, reducing the fault rate of product, improve the service life of product.
The periphery of motor shaft 1 is provided with standstill face 6, and the inner headed face of output connecting shaft 5 is provided with the rotation prevention portion 7 adapted with standstill face 6, is connected by this structure output connecting shaft 5 is fixing with motor shaft 1, sound construction.
The periphery of motor shaft 1 is provided with the locating slot 8 of circumference, and the inner headed face of gear 2 is provided with the centring ring 9 embedded in locating slot 8, and gear 2 can be firmly secured on motor shaft 1 without moving forward and backward.
It is frictional connection between motor shaft 1 of the present utility model and gear 2, can relatively rotate between gear 2 and motor shaft 1, it is able to ensure that the moment of friction needed for transmission, motor shaft 1 is metalwork in the present embodiment, gear 1 and output connecting shaft 5 are the working of plastics being molded on motor shaft 1, contact surface between motor shaft 1 and gear 2 is inclined-plane, this inclined-plane produces frictional force between the two, when moment of face is more than this moment of friction, motor shaft 1 and gear 2 produce relative motion, the teeth that thus can protect gear 2 are without damage, and, when starting moment or gearbox fault, in the case of gear 2 does not turns, motor can also rotate alone, can effectively prevent motor rotation blockage from burning out or break the teeth of gear, reduce the fault rate of product, improve the service life of product.
It should be understood that this utility model parts are few, simple in construction, it is clear that manufacturability is the best, and machining accuracy is easily guaranteed that, sliding corner is little, and bearing capacity is strong；Even if machining accuracy is relatively low, also only sliding corner and bearing capacity is had some slight influences, but mono-directional overrun function is had little to no effect.
In this utility model, gear is all the form that face contacts with motor shaft, it is easy for when surmounting work to form lubricating oil film between the rubbing surface between gear and motor shaft, make the abrasion of rubbing surface between gear and motor shaft close to zero, so can surmount under state at a high speed by long-play, this be also one of characteristic of the present utility model.
This utility model can reach almost axially holohedral symmetry, the construction features of full rigidity, so adapting to operate with ultrahigh speed at a high speed, maximum speed is only dependent upon the strength of materials, the size of transmitted moment of torsion and dynamic balancing level.
