Linner Gears manufactures custom worm gears, worm wheels, and worm shafts to customer drawings and specifications for compact, high-ratio, and precision motion applications. We review tooth geometry, materials, heat-treatment requirements, tolerances, quantities, and inspection needs before production.
Worm Gear Components We Manufacture
Worm Wheels
Custom worm wheels produced to customer drawings with specified tooth geometry, bore, hub, keyway, mounting features, material, and inspection requirements.
Worm Shafts
Single- or multi-start worm shafts manufactured with customer-specified pitch, lead, pressure angle, shaft features, surface finish, and heat-treatment requirements.
Matched Worm Gear Sets
Worm and wheel pairs reviewed together for ratio, center distance, backlash, operating direction, load, speed, lubrication, and service-life requirements.
Worm Gear Specifications We Review
Tooth & Assembly Data
- Module or diametral pitch
- Number of starts, gear ratio, and tooth count
- Pressure angle, lead angle, and hand of helix
- Center distance, backlash, and mounting arrangement
- Mating worm or wheel information
Application & Production Requirements
- Torque, speed, duty cycle, and operating direction
- Material, hardness, heat treatment, and surface finish
- Lubrication, temperature, corrosion, and service environment
- Required accuracy, inspection method, and documentation
- Prototype or production quantity and target delivery schedule
Materials and Applications
Material Considerations
- Bronze and copper-alloy worm wheels
- Steel and stainless-steel worm shafts
- Aluminum or engineering plastics where appropriate
- Hardness, heat treatment, coating, and surface finish
- Material selection based on load, wear, noise, and environment
Typical Applications
- Gearboxes and speed reducers
- Actuators and positioning systems
- Conveyors and lifting mechanisms
- Valve drives and control equipment
- Robotics, instruments, and compact machinery
