Product Description

WH12 heavy load worm drive gear motor reduction for timber grab

Slewing bearing,slewing ring bearing As technology has improved, more 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.The slewing drive uses standard worm technology in which the worm on the horizontal The speed ratio of the shaft depends on the relationship between the number of threads on the worm and the number of teeth in the worm gear or gear.The specifications of the drive and gear depend on the material of the gear. However, most of the drives and gears typically used consist of steel and phosphor bronze. According to a wide range of tests,chilled nickel-phosphorus bronze ranks first in terms of Wear resistance and deformability. The second place on the list is SAE No. 65 bronze. For bronze gears, good castings should have the following minimum physical properties:
Physical characteristics
Ultimate strength yield point
30,000 lbs / psi 12,000 lbs / psi

APPLICATION:

There are many applications where a rotary drive can be used, primary because it is well suited for applications that require load to maintain power and rotational torque.
Typical swing drive applications include, but are not limited to:
Solar tracker
Wind Turbines
Men's lift
Hydraulic machinery
Telehandler
Excavator derrick
Lift
Crane
Drilling equipment
Military equipment
