Worm Gear Motor

Our worm gear motors are designed to produce high torque in a small package size. Worm gear motors are ideal for applications that require self-locking or disconnect functionality, as the output shaft cannot rotate without power. In addition, the worm gear reducer can transmit motion through 90 degrees. With a variety of reduction ratios, precision cut gears, voltages and sizes, we have a DC worm geared motor solution for your application.

The working principle of worm gear motor

A worm gear motor works by transmitting power between a rotating worm and an external gear. The spiral motion of the worm gear significantly reduces space. It also allows for high efficiency and low noise levels. However, this helical motion is not without disadvantages, such as the introduction of sliding wear or friction. Worm gear motors are relatively quiet motors, which makes them ideal for applications where noise is a problem.

The structure of the worm gear motor is very simple. They consist of two parts: the worm gear and the drive shaft. When one or the other gear is turned, the worm gear rotates. As the worm rotates, it wears out on the metal surfaces and on the boundary lubricating parts. Then, as the worm gear leaves the top of the wheel, the surface of the worm gear absorbs more lubricant, and the process repeats on the next rotation.

How to use a worm gear motor

When you’re learning how to use a worm gear motor, it’s important to understand how it works. The torque of such a motor depends on the number of threads, the angle of inclination of those threads, and the number of teeth on the wheel. Another factor that affects the efficiency of a worm gear motor is the amount of friction created at the gear interface. This makes it necessary to lubricate the gears frequently, because if the friction is too high, the gears cannot be driven.

Worm motors are generally quieter than other motors, making them ideal for applications where noise or space is an issue. They can also be used in elevators. Because they produce less noise than other motors, worm gear motors are common in many industries. These advantages have led to the development of several different types of worm gear motors.

Worm and Worm Motors vs Standard Motors

1. Reduction ratio. With a worm gear motor, the reduction ratio is quite large. This means that a tiny worm gear turn can take the leading equipment a considerable distance. This can allow the user to reduce speed and increase torque simultaneously. The welding gear motor’s reduction ratio is comparable to the several stages of reduction of ordinary gears.
2. reverse power. The advantage of a worm gear motor is its limitation of commutation power. Therefore, the gears always move in one direction. This simplifies the whole setup without the need for support. In a standard gear setup, reverse power requires a backstop, which requires more components in the machine.

Our Worm Gear Motors are have some great advantages:

Worm gear motors have many advantages over conventional motors. First, worm gears have a high self-locking ability due to their sliding action. The self-locking ability is proportional to the inclination angle and frictional force between the worm and the gear. Second, these gears are flexible, allowing flexible mounting options. Third, they have fewer moving parts, which means they require less repair and maintenance.
Worm gears usually use steel as the input gear and worm gears are usually bronze. Bronze is a softer metal than steel, which makes it very good at absorbing shock loads. Worm gears require a period of break-in, during which time the metal undergoes work hardening. This time helps to harden the surface of the worm gear due to friction under normal operating conditions. In contrast, hypoid gear sets require no break-in period, allowing them to start operating at peak efficiency from the moment they are installed.
