Plastic worm gears, also known as plastic worm wheels, and their accompanying shaft, are essential components in power transmission systems. They feature a helical tooth design, promoting smooth and efficient motion transfer.
The Plastic Worm Gear and worm Wheels capacity of welle manufacturers including process, material, weight and size is listed as follows:
✧ Plastic Process: Insert& Overmolding, Double Injection molding, Plastic Gear Molding, Prototype Molding, CNC Machining
✧ Plastic Material: Nylon, Acetal/POM, ABS/PC, U-PE, PEEK, etc
✧ Gear Quality: JIS 2( B 1702),JIS N6(B 17020-02),AGMA 12 (390.01~03);
The Plastic Gears are lighter and Quieter than metal gears-pair them with metal worms for Lubrication-free operation. Worm gears use screw threads to make large reductions to shaft speed while transmitting motion at a right angle. They transmit motion from worm to gear and cannot be reversed. For gears and worms to mesh correctly. they must have the same pressure angle and module.
Speed ratio is the ratio by which output shaft speed is reduced, As speed decreases, torque increases.
Welle Acetal gears are lightweight, and resist corrosion and chemicals. They absorb less moisture than nylon gears, so they’re less prone to dimensional changes. They’re best suited for light duty applications, such as prototyping.
Welle Nylon gears are lightweight and stronger than acetal gears.
