Helical speed reducer-motors are most useful solution for your gearbox device. Helical gear units are coaxial device where the gear unit turnout shaft is in-line with the motive shaft. A solid shaft is all of the time used as output shaft. Additional elements – e.g. gear rolls or chain wheels – to change the drive to the driven load are hence required. Results applying helical geared motors are adequate to of an extreme variable quantity speed range. In many cases, helical geared motors act the most cost-effective solution for your driving task.
