The key to choosing a worm gear box is to consider your specific application scenario and requirements. Let me help you sort out the key points so that you can quickly identify the appropriate model.

1、 First, let's take a look at your application scenario

The requirements for the gearbox vary greatly in different scenarios:

Conveyor equipment (such as conveyor belts): requires a large transmission ratio and high torque, while also having a compact structure, suitable for use with worm gearboxes.

Mixing machinery: usually requires high torque and self-locking function to prevent material backflow, and the right angle layout and self-locking characteristics of the worm gear box are very suitable.

Lifting equipment (such as cranes, valve actuators): requires high safety and reliability, and the self-locking function of the worm gear box can effectively prevent reverse driving of the load.

2、 How to choose key parameters

Transmission ratio: The larger the transmission ratio, the greater the output torque, but the output speed will decrease. For example, the worm gear box used in welding equipment usually has a larger transmission ratio to provide sufficient torque.

Torque range: Choose according to your load requirements. For example, the worm gear box used in steel mills has a rated torque of up to 14500mm and can withstand heavy loads.

Self locking function: In scenarios where anti reversal is required (such as lifting equipment or elevators), the worm gear type must be selected, which has self-locking function when the worm lead angle is ≤ 3 °.

Lubrication method: For equipment that operates continuously for a long time (such as 24-hour production lines), it is recommended to use high-efficiency lubrication methods (such as oil lubrication) to avoid overheating of the worm gear shaft system due to low efficiency.

3、 Don't ignore environmental factors

Wet/dusty environment (such as food cleaning, mining): The shaft system needs to be strengthened with sealing (such as 2RS bearings, fluororubber oil seals), and stainless steel or surface galvanizing is preferred as the material.

Corrosive environments (such as chemical and electroplating): Choose planetary shafts, shaft system housings, and gears that are made of 304 stainless steel or corrosion-resistant coatings.

4、 Budget and long-term costs

Low cost requirements (such as small equipment, temporary projects): Worm gear shaft systems have the lowest cost but shorter lifespan.

High budget, long-term use (such as critical production lines, heavy-duty equipment): It is recommended to choose planetary shafts, which have a long lifespan and lower total lifecycle costs.

5、 Safety and reliability

Self locking requirement: For scenarios that require anti reversal (such as lifting equipment, elevators), the worm gear type must be selected.

Fault tolerance: For critical equipment such as medical devices and emergency braking systems, it is recommended to choose parallel shafts, single-stage transmission, with fewer fault points and easy maintenance.
