VE5 Single Axis Small Slew Drive Motor Matched With Planetary Gearbox
Small Slew Drive Description
The worm gear and worm drive have the characteristics of reverse self-locking, which can realize reverse self-locking, that is, only the worm gear can be driven by the worm, but the worm cannot be driven by the worm gear. When the lead angle of the worm is less than the equivalent friction angle between the meshing gear teeth, the mechanism has self-locking properties and can achieve reverse self-locking, that is, only the worm can drive the worm wheel, but the worm cannot be driven by the worm wheel. Such as the self-locking worm mechanism used in its heavy machinery, its reverse self-locking can play a role in safety protection. This feature makes the slewing drive device widely used in lifting, aerial work and other equipment. While improving the technological content of the main engine, it also greatly improves the operation stability and safety factor of the main engine. It is an important embodiment of the safe construction application of mechanical equipment.
