STRUCTURAL DESIGN AND ANALYSIS OF NEW PRECCISION WORM GEAR REDUCER FOR INDUSTRIAL ROBOTS
Precision reducers,as one of the core components of industrial robots
have long been a research focus in the robotics field.Therefore
from the perspective of structural innovation
a new type of precision worm gear reducer suitable for industrial robots was proposed in this paper.By addressing the shortcomings of high relative sliding speed and large meshing clearance in traditional worm gear transmission
a 3D model of
the reducer was established using SolidWorks software. Subsequently
and transmission principle analysis of the reducer were conducted using Ansys Workbench software and Adams software.Through these analyses
the transmission error spectrum of the reducer was obtained
and the influence of different parameters on the load sharing coefficient was analyzed.A prototype reducer was manufactured according to the design parameters
and various performances of the prototype were tested on an integrated test bench for robot reducers; the test results were compared with those of theoretical calculations and simulation analyses.The results showed that the structural design and transmission principle of the developed precision worm gear reducer were reasonable
with a transmission accuracy of 40.13
"
arcseconds and a backlash of 0.47
'
and it operated stably.
