Abstract
The utility model relates to a mecanum wheel of multirow running roller structure has wheel hub, running roller, bearing and running roller dabber, the running roller is the multirow, arranges whenever that it is a plurality of to put, every running roller pass through the bearing support between wheel hub with the running roller spindle, can the free rotation, running roller dabber fixed mounting is on wheel hub, and the axis of running roller dabber becomes 45 with wheel hub 1's axis, the multirow running roller regulation distance of being separated by in mecanum wheel's shaft orientation, staggered arrangement on the circumferencial direction, with the theoretical contact point on ground on the circumference of mecanum wheel's wheel footpath. The utility model discloses a mecanum wheel of multirow (two rows or more multirow) running roller structure can be under the unchangeable prerequisite in mecanum wheel wheel footpath, and the path of increase running roller has improved the running roller atress condition, and under the same round of footpath condition, current more than 3 times of mecanum wheel can be brought up to to the lifting capacity.
Description
Technical field
This utility model relates to a kind of Mecanum wheel, the wheat of a kind of multiple rows of roller arrangement
Ke Namu takes turns.
Background technology
Existing Mecanum wheel technology is, the row's running roller being circumferentially distributed, as shown in Figure 1A, 1B,
Running roller axis is angled with wheel shaft, and assembling rear roll outline forms envelope circle.Prior art bar
Under part, row's running roller is for forming envelope circle, and reduces roller quantity, and running roller length is relatively long, roller
Wheel two ends section radius (running roller path) is relatively small, therefore limits Mecanum wheel lifting capacity.
Under the conditions of prior art, for increasing the lifting capacity of Mecanum wheel, employing method only increases wheat
Ke Namu wheel diameter increases roller diameter (for increasing bearing bore diameter) simultaneously or increases Mecanum wheel number
Measuring two kinds, the former wheel diameter increase is relatively big, and height of the carbody increases, to using on-the-spot suitability fall
Low, the related components cost such as wheel and car body puts into and increases simultaneously；The latter causes wheel and the company of driving
Fitting cost increases, and when two-wheeled lands simultaneously, structure is complicated, adds Design and Machining, system motion control
System and later maintenance difficulty.
Utility model content
Existing for the scheme use used for increasing the lifting capacity of Mecanum wheel in prior art
The suitability of field reduces, causes wheel and the increase of drive connection part cost and two-wheeled to be tied when landing simultaneously
The deficiencies such as structure is complicated, the technical problems to be solved in the utility model is to provide one can be at Mecanum wheel
Wheel footpath constant on the premise of, increase running roller path, improve running roller stressing conditions multiple rows of running roller knot
The Mecanum wheel of structure.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
The Mecanum wheel of a kind of multiple rows of roller arrangement of this utility model, has wheel hub, running roller, bearing
And running roller mandrel, described running roller is multiple rows of, and often arrangement is put multiple, and each running roller is supported by bearing
Between wheel hub and on running roller mandrel, it is possible to freely rotatable；Running roller mandrel is fixedly mounted on wheel hub,
The axis of running roller mandrel is at 45 ° with the axis of wheel hub 1.
Multiple rows of running roller is separated by predetermined distance on the wheel direction of principal axis of Mecanum wheel, hands in a circumferential direction
Staggered arrangement arranges, with the theoretical contact point on ground on the wheel footpath circumference of Mecanum wheel.
Described running roller is 2,4,6 or 8 rows, and the axial direction at wheel hub is arranged.
This utility model has the advantages that and advantage:
1. the Mecanum wheel of utility model employing multiple rows of (two rows or more multiple rows of) roller arrangement,
The path of running roller can be increased, improves running roller stress on the premise of Mecanum wheel wheel footpath is constant
Situation, identical take turns footpath under the conditions of, lifting capacity can bring up to more than 3 times of existing Mecanum wheel.

Detailed description of the invention
Below in conjunction with Figure of description, this utility model is further elaborated.
As shown in Figure 2-5, the present embodiment as a example by 2 row's running rollers, a kind of multiple rows of running roller of this utility model
The Mecanum wheel of structure, has wheel hub 1, running roller 2, bearing 3 and running roller mandrel 4, described roller
Wheel 2 be multiple rows of, and often arrangement is put multiple, each running roller 2 by bearing 3 support between wheel hub 1 with
On running roller mandrel 4, it is possible to freely rotatable；Running roller mandrel 4 is fixedly mounted on wheel hub 1, running roller core
The axis of axle 4 is at 45 ° with the axis of wheel hub 1.
Multiple rows of running roller 2 is separated by predetermined distance, in a circumferential direction on the wheel direction of principal axis of Mecanum wheel
It is staggered, with the theoretical contact point on ground on the wheel footpath circumference of Mecanum wheel.
In the present embodiment, running roller 2 is 2,4,6 or 8 rows, and the axial direction at wheel hub 1 is arranged.
Mecanum wheel wheel, when rotating, has running roller to contact with ground no matter forwarding any angle to, and
And on the circumference of Dian Lun footpath, theoretical contact.As when first row running roller there being a running roller land, then to
Front rotation, before the next running roller difference ground of first row running roller, with first row two in second row running roller
The alternate running roller shifted to install of running roller lands, with the theoretical contact point on ground in the wheel footpath of Mecanum wheel
On circumference.Same row's running roller is neutral gear between adjacent two-wheeled, just by the roller of second row relevant position
Wheel is filled, the most alternate stress, improves running roller stressing conditions, identical take turns footpath under the conditions of, load-carrying
Ability can bring up to more than 3 times of existing Mecanum wheel.
As shown in Figure 6, for having the Mecanum wheel of 4 row's roller arrangement, its arrangement and stress
Principle is identical with the structure of 2 row's running rollers, is not repeated herein.
The application of multiple rows of roller arrangement, can be basically unchanged in Mecanum wheel wheel footpath, somewhat increase wheel
Width, in the case of the big footpath of running roller is constant simultaneously, shortens running roller length, thus increases running roller path,
Increase running roller axle diameter and bearing designation, thus substantially increase the single wheel load of Mecanum wheel
Ability.
