As 1 of famous double enveloping worm gear manufacturers,SGR’s double throated worm gear has advantage of High efficiency, low noise, smooth operation , it increase output torque that mean increasing loading capacity , improved gear accuracy, and extended Long life service period . in SGR double enveloping worm gear design ,based on different ratio, it has Multi-tooth meshed, allowed bigger CHINAMFG load . with the increase of number of driven gear teeth , that mean in contact with the worm significantly increases output torque force. except increasing the number of driven gear teeth in contact with the worm, double enveloping worm gear also increase the contact surface on every gear tooth. The actual gear surface of instantaneous contact between the double throated and the driven gear tooth are in-lines. These lines of contact move across the face of the gear tooth as it progresses through its total time of mesh with the worm. The lines of contact in double enveloping worm gear are configured to increase the force and decrease the stress on every gear tooth.

What are the Noise Levels Associated with Worm Gearboxes?
The noise levels associated with worm gearboxes can vary depending on several factors, including the design, quality, operating conditions, and maintenance of the gearbox. Here are some key points to consider:
- Design and Quality: Well-designed and high-quality worm gearboxes tend to produce lower noise levels. Factors such as gear tooth profile, precision manufacturing, and proper alignment can contribute to reduced noise.
- Gear Engagement: The way the worm and worm wheel engage and mesh with each other can impact noise levels. Proper tooth contact and alignment can help minimize noise during operation.
- Lubrication: Inadequate or improper lubrication can lead to increased friction and wear, resulting in higher noise levels. Using the recommended lubricant and maintaining proper lubrication levels are important for noise reduction.
- Operating Conditions: Operating the gearbox within its specified load and speed limits can help prevent excessive noise generation. Overloading or operating at high speeds beyond the gearbox’s capabilities can lead to increased noise.
- Backlash: Excessive backlash or play between the gear teeth can lead to impact noise as the teeth engage. Proper backlash adjustment can help mitigate this issue.
- Maintenance: Regular maintenance, including gear inspection, lubrication checks, and addressing any wear or damage, can help keep noise levels in check.
It’s important to note that while worm gearboxes can produce some noise due to the nature of gear meshing, proper design, maintenance, and operation can significantly reduce noise levels. If noise is a concern for your application, consulting with gearbox manufacturers and experts can provide insights into selecting the right gearbox type and implementing measures to minimize noise.
Worm Gearbox vs. Helical Gearbox: A Comparison
Worm gearboxes and helical gearboxes are two popular types of gear systems, each with its own set of advantages and disadvantages. Let’s compare them:
|Aspect||Worm Gearbox||Helical Gearbox|
|Efficiency||Lower efficiency due to sliding friction between the worm and worm wheel.||Higher efficiency due to rolling contact between helical gear teeth.|
|Torque Transmission||Excellent torque transmission and high reduction ratios achievable in a single stage.||Good torque transmission, but may require multiple stages for high reduction ratios.|
|Noise and Vibration||Generally higher noise and vibration levels due to sliding action.||Lower noise and vibration levels due to smoother rolling contact.|
|Backlash||Higher inherent backlash due to the design.||Lower backlash due to meshing of helical teeth.|
|Efficiency at Higher Speeds||Less suitable for high-speed applications due to efficiency loss.||More suitable for high-speed applications due to higher efficiency.|
|Overload Protection||Natural self-locking feature provides some overload protection.||May not have the same level of inherent overload protection.|
|Applications||Commonly used for applications requiring high reduction ratios, such as conveyor systems and heavy-duty machinery.||Widely used in various applications including automotive transmissions, industrial machinery, and more.|
Both worm and helical gearboxes have their place in engineering, and the choice between them depends on the specific requirements of the application. Worm gearboxes are preferred for applications with high reduction ratios, while helical gearboxes are chosen for their higher efficiency and smoother operation.
What is a Worm Gearbox and How Does It Work?
A worm gearbox, also known as a worm gear reducer, is a mechanical device used to transmit rotational motion and torque between non-parallel shafts. It consists of a worm screw and a worm wheel, both of which have helical teeth. The worm screw resembles a threaded cylinder, while the worm wheel is a gear with teeth that mesh with the worm screw.
The working principle of a worm gearbox involves the interaction between the worm screw and the worm wheel. When the worm screw is rotated, its helical teeth engage with the teeth of the worm wheel. As the worm screw rotates, it translates the rotational motion into a perpendicular motion, causing the worm wheel to rotate. This perpendicular motion allows the worm gearbox to achieve a high gear reduction ratio, making it suitable for applications that require significant speed reduction.
One of the key features of a worm gearbox is its ability to provide a high gear reduction ratio in a compact design. However, due to the sliding nature of the meshing teeth, worm gearboxes may exhibit higher friction and lower efficiency compared to other types of gearboxes. Therefore, they are often used in applications where efficiency is not the primary concern but where high torque and speed reduction are essential, such as conveyor systems, elevators, automotive steering systems, and certain industrial machinery.
