Q: Are all the internal gears metal too?

Задавает VirginiaJim на 2019-09-04 06:16:23

stevepayor I opened one up, and found all the gears are metal, except for the first large gear (nylon) driven by the motor pinion (brass). This is OK because the torque is low here, and the nylon gear helps keep the drive silent. All of the following gears in the gear train, running at higher torque, are metal.
