Worm gear units Worm gear units General information on worm gear units: Due to their exceptional characteristics, worm gear units are in­ dispensable for a multitude of applications. Worm gear units are the first item to be chosen when implementing high transmission ratios (up to i = 100) within one gear stage. With reference to the transmitted power, worm gear units are the most compact gear type. Due to the line-shaped contact of aligned tooth flanks and the simultaneous alignment of several tooth pairs, the worm gear­ ing is characterised by a uniform, vibration and shock damping force...

Worm gear units Worm gear units Efficiency rating The gear unit efficiency increases at rising running speed on splin­ ing, incrementing rising angle and gearing size. Furthermore, the flank shape, the material combination, the lubrication and the surface properties of tooth flanks have a decisive impact on the efficiency of splining. Starting efficiency rating The lubricant film between the tooth flanks only appear after gearing start at sliding motion. For this reason, the starting effi­ ciency  A is always lower than the service efficiency , whereby when starting at load a higher torque...
