It wipes in order to rotate, while wheel shell 31 being isolated with ground, the direct of wheel shell 31 and road surface is avoided to contact and be worn.
Agv reduced speed drive wheel working principle of the present invention is: driving motor is fixedly connected on axis by motor flange
One end of shell, since ring gear is fixedly connected with axle housing, ring gear is fixed with respect to driving motor shell.Driving motor
Output shaft connect with transmission shaft driven, to drive the active rotation of sun gear, sun gear by with planet pinion
External gear pump transmission because each planet pinion and ring gear are internal messings, ring gear is fixed, so that the number of teeth is smaller
Sun gear drive the biggish planet pinion of the number of teeth to make ground rotation of slowing down in the same direction so that with planet pinion pivot joint
Wheel shell is rotated in deceleration.
Compared with traditional reduced speed drive wheel, the reduced speed drive wheel of waterproof of the present invention has the advantage that tradition
Reduced speed drive wheel runner assembly is inlaid in the inside of fixation kit, when installation, is carried out the component of fixation kit using bolt
Quickly connection, but because each component there are inevitable errors when being connected to machining, causing fixation kit, there are gaps.
And the present invention is socketed in outside the axle housing of fixation kit using waterproof flange, and uses sealing ring by the gap of waterproof flange and axle housing
Filling is got up, and water droplet is prevented to infilter in planetary gear speed-reduction component by the gap of waterproof flange and axle housing；Waterproof flange
One end is fixedly connected with wheel shell, and the boss of waterproof flange is surrounded with groove along side wall, when waterproof flange and wheel shell are connected by screw bolts,
When being splashed the agv driving wheel short time, water droplet can be connected from the bolt of waterproof flange and wheel shell and be infiltered, and groove can be stored few
Water droplet is measured, water droplet is avoided directly to flow into inside wheel shell from the side wall of boss, after leaving splashing region one end time, the water in groove
Natural evaporation is divided to disappear, groove plays the role of the short time and stores a small amount of moisture, and water droplet is prevented to connect from waterproof flange with wheel shell
The gap at place infilters in the planetary gear speed-reduction component in wheel shell.
The present invention is connect with the bolt that sealing ring solves traditional agv reduced speed drive wheel using waterproof flange in the presence of infiltration
The service life of driving wheel can be improved to have prevented the inside that water droplet infilters reduced speed drive wheel ultimate attainmently in problem.
A kind of other structures of the agv reduced speed drive wheel of waterproof described in the present embodiment are referring to the prior art.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, therefore
Without departing from the technical solutions of the present invention, according to the technical essence of the invention it is to the above embodiments it is any modification,
Equivalent variations and modification, all of which are still within the scope of the technical scheme of the invention.
