Product Description
Hourglass worm
Our slewing drives are using hourglass worm technology, in which the worm is shaped to engage more teeth in the gear. This increased tooth engagement results in greater strength, efficiency and durability.
Function
Slewing drives function with standard worm technology, in which the worm on the horizontal shaft acts as the driver for the gear, in general, the shaft is driven by electric gear motor.
Gear ratio
The rotation of the horizontal worm turns a gear about an axis perpendicular to the screw axis. This combination reduces the speed of the driven member and also multiplies its torque; increasing it proportionally as the speed decreases.The speed ratio of shafts depends upon the relation of the number of threads on the worm to the number of teeth in the worm wheel or gear.
