Due to the robot steering wheel output Axile connection structure that the utility model is provided, steering wheel output shaft and steering wheel are using mutual
Steering wheel, is lightly sleeved on the end of output shaft by the wedge structure of cooperation during assembling, then by screwing the side of lock-screw
Formula removes the fit-up gap between steering wheel and output shaft, and carries out locking processing to lock-screw, if sent out after long-time use
Abrasion has been given birth to, again lock-screw has been screwed, gap caused by compensation abrasion.Using such structure, robot rudder is solved
The connectivity problem of machine output shaft and steering wheel, no fit-up gap, and the gap that compensation abrasion at any time is caused in use, transmission
Precision is able to long-term and ensures that its simple and stable structure is reliable, can also support repeated disassembled and assembled to repair, easy to maintenance.
Because the output end of output shaft is positive prismatic table shape, steering wheel mounting hole is the positive prismatic table shape hole being adapted with output end.
Using such structure, its is simple in construction, easy for installation, can reach the effect of no fit-up gap, reliable, weares and teares smaller.
Because the output end of output shaft is taper gear, steering wheel mounting hole is the tapered tooth of the band being adapted with output end
Shape hole.Taper gear has long lifespan, and high load capacity bearing capacity, the advantage of noise reduction damping, using such structure, extends output
The service life of axle and steering wheel, can reach the effect of no fit-up gap, make the operation of output shaft and steering wheel more steady, improve whole
The stability of individual robot running.
Because output shaft is metal material, using such structure, in order to reduce the abrasion between output shaft and steering wheel, prolong
The service life of long output shaft and steering wheel.
In summary, the robot steering wheel output Axile connection structure that the utility model is provided, solves robot steering wheel defeated
The connectivity problem of shaft and steering wheel, no fit-up gap, and the gap that compensation abrasion at any time is caused in use, transmission accuracy
It is able to ensure over a long time, its simple and stable structure is reliable, and service life is long, supports repeated disassembled and assembled maintenance.
