The SE25 worm gear worm shaft slewing drives are used under the automatic turntables. The slewing drives drive the turntables to rotate at a low speed and stop when they reach the designated positions.
Worm gear worm shaft slewing drives have distinct advantages:
Their output torques are large, transmission structures of the worm gear and worm of the worm gear worm shaft slewing drives enable the slewing drives to have large output torques, which are suitable for applications requiring small volumes and large output torques.
They have large gear ratios. The gear ratios of the worm gear worm shaft slewing drives are equal to the teeth numbers of the worm gears. The gear ratios of the worm gear worm shaft slewing drives of the same module and the same size are more than ten times larger than that of the gear type slewing drives. The slewing drives with large gear ratios are especially suitable for use in low-speed occasions, they can be used in conjunction with planetary reducers with small gear ratios, or even directly connected to low-speed motors.
They have the function of self-locking. The worm wheel and worm slewing drives can use the worms to drive the worm wheels to rotate. Conversely, the feature that the worm wheels cannot be used to drive the worms to rotate is mechanical self-locking. This feature is the last guarantee of equipment security in many special applications. The self-locking nature of the worm wheel and worm shaft slewing drives keeps the machines in a stopped position when all the brakes fail.
There are different series and varieties of slewing drives. We need to understand their characteristics, give full play to their advantages, avoid shortcomings, and try to fully stimulate the characteristics of slewing drives according to the requirements of use.
