About Worm Wheel
Products Features
High Reduction ratio in a Small Package
Worm wheel can achieve high reduction ratios easily, sometimes up to 100:1. It can convert the power of high-speed rotation into low-speed and high-torque output, making it particularly suitable for small-space applications that require large torque.
Compact Design
Compact in structure, small in size, light in weight, and easy to install and maintain.
Compared with many traditional gear systems, worm wheel systems occupy less space due to their unique arrangement. This makes it suitable for applications where space is limited.
Self-Locking Functionality
When the lead Angle of the worm is less than the equivalent friction Angle between the meshing teeth, the mechanism has self-locking property. That is, only the worm can drive the worm wheel to rotate. This function is of great significance in many situations where reversal needs to be prevented. It greatly improves the reliability and stability of the equipment operation.
Smooth transmission and low noise
The design of the worm wheel and worm makes it run very smoothly with almost no vibration or noise, which is crucial for many industries.
Built for Strength and Longevity
Worm wheel are made from tough, wear-resistant materials, making them a long-lasting solution for heavy-duty work.
Friction and heat generation
The sliding action creates friction, which will reduce efficiency to 30-50%. The generated heat requires good lubrication to manage.
Process
Design and Planning
According to specific usage requirements and working conditions, determine the parameters of the worm wheel, such as module, number of teeth, helix Angle, center distance, etc.
Draw detailed processing drawings, including the shape, size and tolerance requirements of the worm wheel.
Material preparation
Select the appropriate material. Usually, the worm wheel is made of bronze or cast iron. Inspect the raw materials to ensure their quality meets the processing requirements.
Initial forming
Casting or forging: The basic shape of the worm wheel is first formed from a blank using casting or forging, especially for large-scale production.
Machining and finishing
Turning processing: Turn the blank of the worm gear to remove the excess material and process it into a rough shape and size. Then, the inner hole and end face of the worm gear are turned.
Milling: The initial shape of the tooth groove is machined.
Hobbing or shaping process: Further process the tooth profile to meet the precise meshing requirements.
Grinding processing: The tooth surface of the worm gear is ground to improve surface accuracy and smoothness and reduce tooth surface roughness.
Heat treatment and Surface treatment
According to the material and performance requirements, appropriate heat treatment should be carried out on the worm wheel and worm. It will increase its surface hardness, wear resistance, and lifespan.
Methods: Quenching, tempering, etc.
Surface treatmentinvolves anti-rust treatment of the worm wheel, such as galvanizing and oiling.
Quality control
Inspection: Dimensional and material inspections ensure the gear meets specifications. Use professional measuring tools, such as gear measuring instruments, to inspect parameters like tooth profile, tooth pitch, and center distance to ensure they meet the design tolerances.
Testing: The wheels are also tested under load to verify performance and reliability.
