Description
Technical field
This utility model belongs to robot field, is specifically related to a kind of Motor Shaft structure.
Background technology
Along with the continuous expansion of mobile robot sphere of action, the mankind are the most gradually replaced to enter the landform gather information such as natural disaster, forest fire, nuclear accident, earthquake and mine disaster scene, alleviate disaster and rescue the wounded.Because of the particularity of this type of landform, therefore the portability and obstacle performance to mobile robot proposes high requirement.
The walking mechanism of existing mobile robot is broadly divided into: wheeled, crawler type, polypody, hybrid (as hybrid in wheel lower limb, wheel is carried out hybrid) and specific form (such as polygon rolling type, snakelike slidingtype).Wherein wheel is considered as the highest walking mechanism of energy rotation efficiency, the wheeled feature having himself, have that load-bearing is big, mechanism simple, drive with control relative to facilitate, the speed of travel is fast, work efficiency high.But in the irregular terrain profiles such as seismic ruins, mine disaster be on-the-spot, it is desirable that smooth running and the strong portable mobile robot of obstacle climbing ability.
Conventional Motor Shaft structure is motor both sides, wheel office.When robot on irregular ground up walk time, wheel there will be and inevitably jolts, and now, the active force of wheel acts on wheel shaft completely, if motor or reduction box are directly connected with line shaft, to a certain extent motor or reduction box can be caused damage.Therefore, in order to protect motor and reduction box, generally between wheel shaft and motor or the power output shaft of reduction box, upper coupling is added in order to buffer.But, traditional axial straight line reach shaft coupling not only can increase body width, it is also possible to can increase tare.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of simple for structure reliable and that efficiency is high Motor Shaft structure.
For reaching above-mentioned purpose, this utility model following technical scheme of offer: a kind of Motor Shaft structure, including wheel, motor and shaft coupling, also include motor cylinder and elastic 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 elastic 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 elastic device is connected with flange coupling and wheel carrier respectively.
Further, described elastic device is spring.
Further, described elastic device is shaft and yielding coupling.
The beneficial effects of the utility model are: this utility model overcomes deficiency of the prior art; by reducing the width between wheel; provide a kind of reliable, compact, light Motor Shaft structure simple for structure; achieving the effective protection to motor and reduction box during obstacle detouring, being available for mobile robot, barrier-exceeding vehicle etc. needs the mobile device at uneven terrain and smooth ground running to use.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, this utility model provides drawings described below to illustrate:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in the figure, Motor Shaft structure in this utility model, including wheel, motor 2 and shaft coupling 3, also include motor cylinder 4 and elastic 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 elastic 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 be rotated 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 elastic device 5.In the present embodiment, wheel 1 can be played a supporting role by bearing 6, and the active force making wheel 1 produce in jolting acts on the bearing 6 of rigidity, thus avoids the damage being caused shaft coupling and motor.It addition, by the inner side that wheel 1 is arranged on flange coupling, body width can be reduced, thus reduces 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 elastic device 5 is connected with flange coupling and wheel carrier 7 respectively.Wheel carrier 7 structure is both easy to connect, install, and can reduce again barrier-exceeding vehicle weight further, thus improve the motility of vehicle body.
Elastic device 5 in the present embodiment is spring.Certainly, it is possible to use shaft and yielding coupling or other there is the device of shock-absorbing capacity.
Some complicated landform are higher to the portability requirements of mobile robot, and barrier-exceeding vehicle own wt is the principal element affecting portability.This utility model reduces the width between wheel, and car body can be allowed to become compacter, light；And when non-flat forms ground motion, this structure can play again protection motor and the effect of reduction box.
Finally illustrate is, preferred embodiment above is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from this utility model claims limited range.
