96 Tooth Worm Gear Assembly

The 96 tooth worm gear assembly comes assembled with the gear, sleeve, backplate bearing, axle sleeve bolt, and snap rings. 1/4 inch easy-reach grease fittings are included. The gear fits standard gear plates used in flat-plate hoists.

There are two options for the single thread worm assembly: bronze or cast iron. 932 bronze is used for the bronze gear. Without the sleeve installed, both gears have 2.875-inch bores. Their hub depths are 2 inches. 96 tooth gears are named after the number of teeth they have in the thread. The gear measures 12 3/4 inches wide by 12 3/4 inches high.

Worm gears are mounted on the gear plate at the top mounting holes. An assembly block is installed around the middle of the gear plate to match up the gear. When the assembly block’s drive shaft rotates, the worm gear inside the assembly block turns the 96-tooth gear. There is a pulley mounted on the drive shaft of the assembly block, and there is a smaller pulley mounted on the drive shaft of the motor, which is mounted at the bottom of the gear plate. On both pulleys, a belt is installed. The motor rotates its drive shaft in response to the motion of the pulleys on the motor and assembly block, which then turn the worm gear inside the assembly block, which turns the 96 tooth gear. A drive pipe installed through the 96 tooth gear’s bore causes the drive pipe to rotate. If the motor is turning in one direction, or the other, the drive pipe will either raise or lower whatever is attached to it.

Extended Block Worm AssemblyNever use the same material for both worm gears. The use of steel-on-steel or bronze-on-bronze is not recommended for flat-plate hoists. Return policy.
