Worm gear slewing drive and worm structure is often used to transfer motion and power between two staggered shafts.Worm gear and worm in the middle plane is equivalent to gear and rack, worm and screw shape is similar.
Mechanism characteristics
1. Large transmission ratio can be obtained, which is more compact than the staggered helical gear mechanism.
2. The meshing surfaces of the two wheels are in line contact, and the bearing capacity is much higher than that of the staggered shaft helical gear mechanism.
3. Worm drive is equivalent to spiral drive, multi-tooth meshing drive, so the drive is stable and has little noise.
4. Self-locking.When the leading Angle of the worm is less than the equivalent friction Angle between the meshing gears, the mechanism has self-locking property, and can realize reverse self-locking, that is, only the worm drives the worm, but not by the worm wheel drives the worm.Such as in the lifting of the use of self-locking worm mechanism, its reverse self-locking can play a role in safety protection
Description
There are no special limitations of mounting angles and positions of this series of products. It can be mounted horizontally, vertically and inclined. Enclosed slewing drives are assembled of enclosed housing, slewing bearing, worm shaft and other parts. Users can choose electric motors or hydraulic motors as the driving power. It can slew 360 degrees clock-wise or otherwise. The slewing drive is compact and it is also easy to mount and maintain in comparison with other types of driving devises.
Features
It adopts enclosed design and the protection level can reach IP65. It can effectively prevent dust, rain and other hostile environments. It suits field usage such as desert, alpine and other hostile environments.
1.Products are easy to mount and maintain.
2.The design and mounting dimensions are international or domestic universal dimensions. It is easy for the users' replacements in the future.
Tilting Moment Torque: Torque is the load multiplied by distance between the position of load and the center of slewing bearing. If the qorque generated by load and distance is greater than the rated tilting moment torque, slewing drive will be overturned.
Radial load: Load vertical to the axis of slewing bearing
Axial load: Load parallel to the axis of slewing bearing
Holding torque:It is the reverse torque.When the drive is rotating reversely, and parts are not damaged,The maximum torque achieved is called holding torque.
Self-locking: Only when loaded, the slewing drive is not able to reverse rotate and thus called self-locking.
Coresun Drive Slewing Bearing Production Precision and Backlash Testing.Ensuring smooth operation.
