Working principle
Transmission shaft: The transmission shaft of the helical gear worm reducer is equipped with a transmission helical gear. When the driving shaft rotates, the driving bevel gear and the worm gear mesh with each other to transmit power. Worm gear transmission: Worm gear consists of worm gear and worm gear. When the worm wheel rotates, the thread cutting action of the worm will push the worm wheel tooth surface to rotate. Because the worm wheel has fewer teeth and larger pitch, the worm wheel rotates slowly, resulting in a deceleration effect. Deceleration effect: due to the special structure of worm gear meshing transmission, a larger transmission ratio can be realized, thus achieving the deceleration effect. Through the transmission of the helical gear worm reducer, the high-speed rotation of the driving shaft is converted into the low-speed and high-torque output of the driven shaft. Stability and silence: The bevel gear worm reducer has a large contact area and good transmission stability because of the bevel cutting of the worm gear and the continuous contact with the worm gear tooth surface. At the same time, it can effectively reduce noise and vibration, and the operation is relatively stable. Through the above principle, the helical gear worm reducer can realize the effect of high-speed rotation of the driving shaft to low-speed and high-torque output of the driven shaft. It has the advantages of simple structure, high transmission efficiency and strong bearing capacity, and is widely used in machinery manufacturing, conveying equipment, automation and other fields.
