Structure
Knowing the worm drive motor’s construction guarantees lifespan and best performance when choosing the appropriate motor for a certain application.
Electric Motor
- Can be a DC (brushed/brushless) or AC (single/three-phase) motor.
- Converts electrical energy to mechanical, rotating the worm gear.
Worm
- An apparatus shaped like a screw.
- Engages the worm wheel, causing it to rotate and transmit motion and power.
Worm Wheel (Gear)
- A gear similar to a spur gear, meshing perpendicularly with the worm.
- Reduces speed & increases torque to the output shaft upon receiving motion from the worm.
Output Shaft
- Joined with the worm wheel.
- Delivers the reduced speed and increased torque to the connected load or mechanism.
Housing
- Usually composed of cast iron or aluminum.
- Protects components, supports structure, and aids heat dissipation.
Bearings
- Support the motor shaft, worm & output shaft.
- Reduce friction and wear, ensuring smooth rotation of the shafts.
Lubrication
- Grease or oil, depending on the design.
- Reduces friction, enhances efficiency, and prolongs component life.
Seals and Gaskets
- keeps lubricant inside the housing and stops the entry of dust, grime, and moisture.
