The motor shaft extension structure disclosed by the invention overcomes the disadvantages in the prior art, and the motor shaft extension structure with a simple, reliable, compact and light structure is provided through the reduction of width between the wheels, the motors and a gearbox can be effectively protected in the obstacle-crossing process, and the structure is applicable to mobile robots, obstacle-crossing vehicles and other mobile equipment which travel on uneven terrain and even terrain.
Description
Technical field
The invention belongs to robot field, it is specifically related to a kind of Motor Shaft structure.
Background technology
Along with the continuous expansion of mobile apparatus people's sphere of action, the mankind are now replaced to enter the landform acquisition of informations such as natural disaster, hill fire, nuclear incident, earthquake and mine disaster scene, alleviate disaster and rescue the wounded gradually. Because of the singularity of this type of landform, therefore the portability and obstacle detouring performance to mobile apparatus people proposes high requirement.
The travel mechanism of existing mobile apparatus people is broadly divided into: wheeled, track type, polypody, hybrid (as hybrid in wheel leg, wheel is carried out hybrid) and special shape (such as Polygons rolling type, snakelike sliding type). Wherein wheel is considered as the most effective travel mechanism of energy rotation, the wheeled feature having himself, has that load-bearing is big, mechanism is simple, drive the features such as convenient, walking speed fast, working efficiency height relative to control. But in the irregular landform such as seismic ruins, mine disaster be on-the-spot, it is necessary to be the portable mobile robot that smooth running and obstacle detouring ability are strong.
Conventional Motor Shaft structure is motor both sides, wheel office. When robot walks on irregular ground, wheel there will be inevitable jolting, and now, the reactive force of wheel acts on wheel shaft completely, if motor or reduction box are directly connected with power shaft, to a certain extent motor or reduction box can be caused damage. Therefore, in order to protect motor and reduction box, between wheel shaft and the power output shaft of motor or reduction box, usually add upper coupling in order to buffering. But, traditional axial straight line stretches out formula shaft coupling not only can increase vehicle body width, it is also possible to can increase tare.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of reliable and Motor Shaft structure that efficiency is high simple for structure.
For achieving the above object, the present invention provides following technical scheme: a kind of Motor Shaft structure, comprise wheel, motor and shaft coupling, also comprise motor cylinder and elasticity device, described shaft coupling is flange coupling, and described motor is connected with flange coupling and is arranged in motor cylinder, and described wheel is arranged on motor cylinder by bearing, described flange coupling is connected with wheel by elasticity device, and described wheel is positioned at inside flange coupling.
Further, described wheel is provided with wheel carrier, and described wheel carrier is set with and is fixed on outside bearing, and described elasticity device is connected with flange coupling and wheel carrier respectively.
Further, described elasticity device is spring.
Further, described elasticity device is shaft and resilient coupling.
The useful effect of the present invention is: instant invention overcomes deficiency of the prior art; by the width reduced between wheel; provide a kind of reliable, compact, light Motor Shaft structure simple for structure; achieve the available protecting to motor and reduction box in obstacle detouring process, can need at the mobile equipment of uneven terrain and smooth ground running for mobile apparatus people, barrier-exceeding vehicle etc.
Accompanying drawing explanation
In order to make the object of the present invention, technical scheme and useful effect clearly, the present invention provides following accompanying drawing to be described:
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the one-piece construction schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in the figure, Motor Shaft structure in the present invention, comprise wheel, motor 2 and shaft coupling 3, also comprise motor cylinder 4 and elasticity device 5, described shaft coupling 3 is flange coupling, and described motor 2 is connected with flange coupling and is arranged in motor cylinder 4, and described wheel 1 is arranged on motor cylinder 4 by bearing 6, described flange coupling is connected with wheel 1 by elasticity device 5, and described wheel 1 is positioned at inside flange coupling.
Concrete, wheel 1 is arranged on motor cylinder 4 by bearing 6 and can rotate around bearing 6 outer ring, and inner ring then keeps fixing with motor cylinder 4, and motor 2 drives flange coupling to rotate, and flange coupling then drives wheel 1 to rotate by elasticity device 5. In the present embodiment, wheel 1 can be played a supporting role by bearing 6, makes effort that wheel 1 produces in jolting on the bearing 6 of rigidity, thus avoids the damage that shaft coupling and motor cause. In addition, by wheel 1 being arranged on the inner side of flange coupling, vehicle body width can be reduced, thus reduce barrier-exceeding vehicle own wt.
Wheel 1 in the present embodiment is provided with wheel carrier 7, and described wheel carrier 7 is set with and is fixed on outside bearing 6, and described elasticity device 5 is connected with flange coupling and wheel carrier 7 respectively. Wheel carrier 7 structure both was convenient to connect, was installed, and can reduce again barrier-exceeding vehicle weight further, thus improve the handiness of vehicle body.
Elasticity device 5 in the present embodiment is spring. Certainly, it is possible to adopt shaft and resilient coupling or other devices with shock-absorbing capacity.
The portability of mobile apparatus people is required higher by some complicated landform, and barrier-exceeding vehicle own wt is the principal element affecting portability. Present invention decreases the width between wheel, car body can be allowed to become compacter, light; And when moving on non-flat forms ground, this structure can play again the effect of protection motor and reduction box.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical scheme of the present invention and unrestricted, although by above preferred embodiment to invention has been detailed description, but those skilled in the art are to be understood that, in the form and details it can be made various change, and do not deviate claims of the present invention limited range.
