NMRV040 reducer transmission: The failure mode of NMRV40 reducer worm drive is similar to gear transmission (gear reducer), and there are also forms of pitting, wear, gluing, and worm gear teeth breaking.Among them, the pitting corrosion of the tooth surface and the wear of the worm gear tooth surface are common. In addition, gluing also occurs from time to time.The above-mentioned failure is mainly due to the relatively high sliding speed between the meshing tooth surfaces, especially in the cylindrical worm drive, the lubrication angle 8 is too small, and the dynamic pressure oil film cannot be formed, so that the gnawing efficiency is low and the temperature rises.In addition, factors such as insufficient stiffness of the worm or manufacturing and installation errors can also lead to the above-mentioned failure modes.The breaking of worm gear teeth is mostly caused by the excessive thinning of the tooth thickness after the gear teeth are worn, and the serious unbalanced load caused by large installation errors.In short, because the worm gear structure and the mechanical properties of the materials used are better than those of the worm gear teeth, the worm gear teeth are the weak link of the two.If the transmission type and parameters are selected reasonably during the design, the appropriate material combination is selected, and the good lubrication method and heat dissipation measures are matched, the anti-wear and anti-glue lubricating oil is selected, and the processing and installation accuracy can be improved. To improve and extend the service life.
