The multi-row type omnidirectional wheel comprises hubs and driven wheels, wherein the hubs are arranged in a manner of two or more rows inside and outside and are alternately staggered at an angle of 22.5 degrees to ensure that at least one small wheel of the omnidirectional wheel is in contact with the ground surface. An outer hub bracket and an inner hub bracket are directly matched and connected through a hub center. A support shaft is mounted in a U-shaped groove of each hub; each two support shafts are connected with each other to form a regular octagonal shaft chain; each support shaft is provided with a spindle body driven wheel; and the joints of the shaft chains are fixed through cover plates with barbs. Each driven wheel adopts an integral structure of vulcanizing each bearing sleeve and rubber at the outer ring of each spindle body, so that motion precision of the omnidirectional wheel is guaranteed. According to the invention, insertion type structures are designed on the inner hubs and the outer hubs, so that multi-row parallel installation can be realized, bearing capability of the omnidirectional wheel is improved efficiently. The multi-row type omnidirectional wheel, disclosed by the invention, has the advantages of overcoming the defect of an overlarge gap between adjacent small wheels of the traditional omnidirectional wheel, improving driving smoothness of driving wheels and guaranteeing vibration precision of a robot at runtime.
Description
Technical field
The present invention relates to the robot movement field, relate in particular to a kind of many rows formula omnidirectional wheel.
Background technology
Omnidirectional's wheel is employed in the big driving wheel frame mode of the some steamboats of rectangular distribution on every side mostly at present; Driving wheel is by motor-driven; Steamboat can freely roll; What make that robot receives when the driving wheel vertical direction is breakked away is friction of rolling, has reduced friction drag, plays good rolling effect.Omnidirectional's wheel generally is made up of 2 interior outer wheel hubs; And have a certain degree and stagger; Contact the stationarity that keeps driving wheel to rotate in turn with ground through the steamboat on the different wheel hubs, but the angular clearances between the common adjacent steamboat is bigger, has influenced the stationarity that driving wheel rolls.
Summary of the invention
It is excessive to the objective of the invention is to overcome the angular clearances that present omnidirectional takes turns between the adjacent steamboat, the problem that the rolling continuity is relatively poor.Be staggered into inside and outside design-calculated omnidirectional of institute wheel supporting part adopts 22.5 degree angles inside and outside two-layer or two-layer more than complementary wheel hub structure; Be evenly distributed with 8 flower wheel wheels around every layer of wheel hub; Reduce the angular clearances between the adjacent flower wheel, interior outer wheel hub support Design becomes plug formula structure, can realize that many rows of omnidirectional's wheel install; Thereby bigger load-carrying capacity and good wheel ground contact continuity are provided, improve the stability of rotation property of omnidirectional's wheel.
The technical scheme that technical solution problem of the present invention is taked is following:
The present invention includes the outer wheel hub support, inner wheel hub support, pivot shaft, spindle flower wheel, fastening cover plate.
All there is the ladder boss structure wheel hub center of outer wheel hub support of the present invention and inner wheel hub support, and the front end boss of inner wheel hub support can extend into the rear end boss of outer wheel hub support, forms assembling and positioning relation.Outer wheel hub support and inner wheel hub support be 4 cylinder boss structures of rectangular distribution on the support circumference; The cylinder boss locations complementary; The outer wheel hub support directly cooperates connection with the inner wheel hub support through these 4 cylinder boss structures; And use bolt, back outer wheel hub support and inner wheel hub support are installed are 22.5 ° of angles.The edge of outer wheel hub support and inner wheel hub support all has U type groove, is used to install pivot shaft, and U type groove is inner all to have screw with wheel hub holder tip, is used for fixing pivot shaft and fastening cover plate respectively.
Four circular holes are all arranged on inner wheel hub support according to the invention and the outer wheel hub support, and saving in material under the situation that does not reduce structural strength reduces weight, and the wheel hub timbering material can replace aluminum alloy by the highstrenghtpiston, the saving cost.
Pivot shaft of the present invention two ends are flats; And have screw, and can be end to end in twos, 8 pivot shafts are interconnected to form octagon axle chain structure; Angle between the adjacent supports axle is 135 degree; Pivot shaft pressure in the U type groove of wheel hub holder, can be shared by the octagon axle chain structure that pivot shaft is formed through the M1.6 screw retention in the junction of pivot shaft and pivot shaft, improves the single-piece structural strength.
Fastening cover plate of the present invention is fan-shaped, and has overhead structure, and the barb place is connected with the distal end of wheel hub holder; The narrow end of fastening cover plate has through hole; On the wheel hub holder, fastening cover plate can be pushed down pivot shaft, prevents that pivot shaft from dropping in U type groove through the M3 screw retention.
Spindle steamboat of the present invention is by plain bearing, bearing carrier ring, and the spindle outer ring is formed; Pivot shaft is connected with plain bearing, plain bearing adapter shaft bearing sleeve, and bearing carrier ring links to each other with the spindle outer ring; Spindle outer ring and bearing carrier ring adopt vulcanization of rubber integrative-structure; Both sides, spindle outer ring contact with the rib of plain bearing respectively, guarantee that it can not produce longitudinal travel, and the antifriction rubber material is adopted in the spindle outer ring.
Compared with prior art, beneficial effect of the present invention:
(1) interior outer wheel hub support directly cooperates connection through the boss structure on wheel hub center and the circumference, and realizes the Fast Installation of many row's wheels through the modular design of wheel hub, but not is confined to the installation of two row's wheel hubs, has enlarged the carrying scope of omnidirectional's wheel.
(2) interior outer wheel hub support adopts the fluting design, and octagon axle chain is embedded in the U type groove of wheel hub, fixes through the fastening cover plate that has barb, and the flower wheel convenient disassembly is convenient to safeguard.
(3) 8 pivot shaft head and the tail are connected to form octagon axle chain with screw, and are fixed in the U type groove of interior outer wheel hub support, and structure is more firm.When single flower wheel landed, adjacent two pivot shafts can play the effect of the power of sharing.
(4) each wheel hub is distributed with 8 steamboats, has reduced the angular clearances of adjacent flower wheel, has strengthened the continuity that flower wheel contacts with ground, thereby improves the robust motion of omnidirectional's wheel.
