The shaft-mounted reducer can obtain a large transmission ratio when it is operated. The load capacity of the equipment is much higher than that of the staggered shaft helical gear mechanism. The worm drive is equivalent to the screw drive, which is a multi-tooth mesh transmission, so the transmission is stable and the noise is very small. Self-locking. When the lead angle of the worm is smaller than the equivalent friction angle between the meshing teeth, the mechanism has self-locking property, and the reverse self-locking can be realized, that is, the worm wheel can only be driven by the worm, and the worm can not be driven by the worm wheel.
If the shaft-mounted reducer is a self-locking worm mechanism used in heavy machinery, its reverse self-locking property can provide safety protection. The transmission efficiency is low and its wear is serious. When the worm gear is meshed and transmitted, the relative sliding speed between the meshing teeth is large, so the friction loss is large and the efficiency is low. On the other hand, the relative sliding speed is large, causing severe wear on the tooth surface and serious heat generation. In order to dissipate heat and reduce wear, materials with better anti-friction and anti-wear properties and good lubrication devices are often used, so the cost is high. .
The heat-treated tooth surface hardness of the shaft-mounted reducer is HRC56-62 core is ≥HRC30, and the worm gear shaft of the reducer low-speed output is made of 45 steel or other materials with comparable mechanical properties. The hardness of the quenching and tempering treatment reaches HB217-255, the shaft The most important thing about the installed reducer is the choice of worm gear material.https://www.delinggearbox.com/
