Rotary speed reducer is a kind of integration of driving power
source of full circle rotary reducer transmission mechanism. Use a
rotary bearing as transmission follower and adhesion mechanism, efficient allocation of driving
power source and the main transmission parts, which have functions
of rotary, speed reduction and drive function, with advantages of simple structure, manufacture
and maintenance convenient. Rotary drive device can be basically
divided into single worm drive rotary drive device and double worm drive rotary drive device
Characteristics of worm gear and worm mechanism:
1. Large transmission ratio, which is more compact than staggered
helical gear mechanism
2.The meshing tooth surfaces of the two wheels are in line contact,
and its bearing capacity is much higher than that of the staggered
helical gear mechanism
3.Worm transmission is equivalent to spiral transmission, which is
multi-tooth mesh transmission, so the transmission is stable and
the noise is small
4. Self-locking.
Application of rotary drive:
Double worm slewing drive for construction machinery, slewing drive
for truck crane, slewing drive for heavy-duty flatbed transport
truck, slewing drive for aerial work truck drive, rail car slewing drive, dirt suction car slewing
drive, rotary claw slewing drive, bridge testing car slewing drive
device, rotary drive device, wind power yaw rotary drive device, solar energy rotary drive.
