Description
Technical field
The utility model is related to wheeled road walking mechanisms, are specially that a kind of omnidirectional's wheel load capacity improves structure.
Background technology
Omni-directional wheel is the support component of wheeled road walking mechanism, it can not only be used as by a normal wheels turns
Driving wheel uses, and controlled device can also be made to realize transverse shifting.Therefore, this element be widely used in trolley, conveyer,
The occasions such as freight, luggage truck.
Existing omni-directional wheel is broadly divided into two kinds, and one kind is two-wheel hub structure, and several driven rollings are uniformly distributed on wheel hub
Wheel, adjacent rollers stagger certain angle；Another kind is single-wheel hub structure, and it is different alternately to install two kinds of diameters in circumference of hub
Idler wheel, while the outer profile of each idler wheel is on same circumference.
When two-wheel hub structure omni-directional wheel rotates, idler wheel gabarit differs with hub edge height, and ground connection position can be in two wheels
Idler wheel on hub switches over, and the easy generation of difference in height of idler wheel gabarit and hub edge is laterally left and right to wave, so as to cause
The unstable phenomenon of omni-directional wheel transverse movement.
When single-wheel hub structure omni-directional wheel rotates, since the gabarit of each idler wheel is on same circumference, it can protect
Demonstrate,prove the continuity and stationarity of omni-directional wheel lateral movement.
The idler wheel of above two structure omni-directional wheel is supported using support shaft with bearing, and in order to ensure that idler wheel is being tied
The contact point of continuity on structure, support shaft and wheel hub is usually only positioned at two of idler wheel both sides.Obviously, consider supporting point across
The influence of degree, this two point-supported structure easily limit the load capacity of omni-directional wheel, should especially when idler wheel is wider
Problem is more prominent.
Utility model content
In view of the deficiencies of the prior art, technical problem to be solved in the utility model is to propose a kind of improve to carry energy
Omnidirectional's wheel load capacity of power improves structure.
The omnidirectional's wheel load capacity that can be solved the above problems improves structure, and technical solution is included in and circumference on wheel hub
The ball support machine for being supported on corresponding idler wheel bottom is equipped on spaced big roller and the corresponding wheel position hub face of trundle
Structure, the ball supporting mechanism include the retainer of matching wheel hub surface shape, ball, each ball are laid in the retainer
Lower part with wheel position hub face be in rolling contact, top and the idler wheel of each ball are in rolling contact.
A kind of structure of the retainer is the ball carrier bar group being made of axial a plurality of ball carrier bar side by side, length side
Include the chain block being hinged successively to each ball carrier bar for circumferencial direction, each chain block center offers the hole of bead of installation ball；It is right
Should in a plurality of ball carrier bar in opening up a plurality of groove on wheel position hub face, the section of the groove for matching ball sphere diameter semicircle
Shape.
The quantity of the ball carrier bar is determined that chain number of blocks is by corresponding to wheel position hub face gabarit by the length for axially taking turns position hub face
Length (circumferencial direction) determines that axial wheel position hub face and wheel position hub face gabarit length are longer, the number of corresponding ball carrier bar and chain block
Amount is more.
For effective fixed retainer, the both ends in the ball carrier bar group length direction are pressed on pair respectively by axial pressing plate
On the both ends that a hub face should be taken turns, the both sides of each groove are equipped with corresponding to the hinged part of adjacent chain block makes hooking make itself and wheel in chain block
The hook that position hub face fits closely is sincere.
Ball carrier bar is made to imbed wheel position hub face with appropriate length, one end of each ball carrier bar is equipped with adjustable length
Connector, the pressing plate are pressed on the connector of ball carrier bar corresponding end.
For all balls is enable to be contacted with idler wheel, the wheel position hub face corresponds to the curved surface of idler wheel bottom shape for matching.
The beneficial effects of the utility model：
1st, in the utility model structure, the ball one side back-up roller wheel in ball supporting mechanism retainer, on the other hand
It is contacted with wheel position hub face, adds supporting point of the idler wheel on wheel position hub face, disperseed the external load for being applied to idler wheel, so as to
The load capacity of omni-directional wheel is improved, has widened the application range of omni-directional wheel.
2nd, in the utility model structure, ball carrier bar is formed by connecting by the chain block being hinged successively, and ball carrier bar group is enable to fit
Wheel position hub face of different shapes is answered, it is achieved thereby that ball carrier bar group is with taking turns fitting closely for position hub face.
3rd, in the utility model structure, one end of ball carrier bar is equipped with the connector of adjustable length, can be according to idler wheel not
Same size adjusts the length of ball carrier bar, and ball carrier bar is made to imbed wheel position hub face with suitable length, is additionally operable to adjust ball and rolling
The Support Position of wheel.
4th, in the utility model structure, chain block is lived equipped with the sincere hooking of hook, ensures ball carrier bar in omni-directional wheel normal operation
It does not fall off.
5th, in the utility model structure, the corresponding wheel position hub face of idler wheel is curved surface, can make the ball on every row's ball carrier bar
It can be contacted with idler wheel, avoiding row's ball among only can contact with idler wheel, and both sides ball can not be in close contact with idler wheel
The problem of.
