Transmission Parts Aluminum Worm Gear Set Motor Wheel Diameter Shafts Pin Nylon Bore Tooth Brass Stainless Steel Gear Sets
Product Description
The mating worm gear mounts on a specialized Steel 1/4" D-Bore Barrel Hub for Worm Gear to create a reliable junction between the gear and the shaft it's turning. The worm and the worm gear are designed so that you can run them 0.75" apart from one another; the same spacing you'll find on Ever-power and other components within the build system. Aside from the massive reduction in speed and the increase in torque, these worm gears will lock in place when at rest so you don't have to worry about an outside force backdriving the mechanism driving them.
Applications of Worm Gear Sets:
The distinct characteristics of worm gear sets - particularly their ability to achieve high reduction ratios in a single stage, their self-locking capability, and their smooth, quiet operation - make them ideal for a wide range of specific applications:
-
Lifting and Hoisting Equipment:
- Elevators and Lifts: The inherent self-locking feature is crucial for safety, preventing the load from falling if input power is lost. They provide the necessary high torque for lifting heavy loads.
- Cranes and Winches: For controlled lifting, lowering, and holding of loads, where precise positioning and the ability to hold a position are important.
- Chain Blocks and Hoists: Provide the mechanical advantage for manual or powered lifting, often with a non-reversing safety feature.
-
Automated Gates and Barriers:
- Automatic Security Gates: The self-locking mechanism ensures that the gate remains closed and cannot be manually forced open when the motor is disengaged, providing a built-in security feature.
- Boom Barriers (Parking Garages): For controlled raising and lowering, and holding the barrier arm in position.
-
Conveyor Systems:
- Used in various material handling conveyors, especially those requiring high torque at low speeds or where the self-locking property is beneficial to prevent rollback when stopped or to hold materials in place on inclines.
-
Machine Tools and Automation:
- Indexing Tables: For precise rotational positioning in manufacturing and assembly processes.
- Packaging Machinery: Used in various mechanisms requiring precise, often slow, and high-torque movements (e.g., filling, capping, labeling, sealing). Their quiet operation is also a benefit here.
- Robotics: Found in certain robot joints or linear actuators where compact size, high torque, and the possibility of self-locking are advantageous.
- CNC Machine Tools and 3D Printers: For driving certain axes or components where fine, controlled motion and a high reduction ratio are needed.
-
Consumer Products:
- Tuning Mechanisms: Ubiquitous in musical instruments like guitars, basses, violins, and mandolins for fine and precise string tension adjustment.
- Fishing Reels: For smooth retrieval, high gearing ratios, and the ability to hold line under tension.
- Window and Door Actuators: In some automotive power windows, power seats, or home automation systems where slow, powerful, and self-locking motion is required.
- Wiper Motors: In vehicle windshield wiper systems.
-
Steering Systems:
- In some automotive steering systems (especially older designs or heavy-duty vehicles), worm gears convert the rotational motion of the steering wheel into the linear motion required to steer the wheels.
-
Valve Actuators:
- Used in industrial valve actuators to provide the high torque needed to open and close large or high-pressure valves, often with a self-locking feature to maintain valve position.
