Application of worm gear and worm reducer self-locking function
Worm gear reducer is a power transmission mechanism, the use of gear speed converter, the motor (motor) to reduce the number of rotation to the desired number of rotation, and get a larger torque mechanism. Worm gear and worm reducer are widely used in the transmission of power and motion. It can be seen in the transmission system of all kinds of machinery, from ships, cars, locomotives, heavy machinery for construction, processing machinery and automatic production equipment used in the machinery industry, to common household appliances in daily life, clocks and so on.
In the transmission mode of the worm gear reducer, the worm gear drive has the characteristics that other gear drives do not have, that is, the worm can easily turn the worm gear, but the worm gear can not turn the worm. This is because the structure and transmission of the worm gear is achieved by friction. The self-locking function of worm gear and worm drive is very useful in mechanical applications, such as winches, conveying equipment and so on. However, it is also because of the friction transmission mode of worm gear and worm gear, which also causes the transmission efficiency of worm gear and worm gear to be much lower. Not all the worm gear reducer has a good self-locking function, the self-locking function of worm gear to achieve a certain speed ratio to achieve. This is related to the lead Angle, that is, the worm self-locking function of the small speed ratio worm gear is not so ideal.
