Short Block Worm Assembly

The Short Block Worm Assembly has a 2-inch bearing block, a worm on a driveshaft, and an aluminum housing with 1/4 inch grease fittings. Attaches directly to the gear plate. The assembly has standard flat-plate mounting holes.

The assembly is fitted with standard flat-plate mounting holes Factory assembled. Blocks are fitted with flange bushings. They have 1/4-inch grease fittings, which can be accessed easily.

The bronze worm is featured on the Standard series flat-plate boat hoists. On the gear plate, the bronze worm turns the 96-tooth cast iron worm gear. When the flat-plate hoist is assembled, the cast iron worm gear turns the drive pipe.

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.

There are no mounting fasteners, key stock for the pulley, or pulley included.

Short 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.
