·Overview
A gearbox, invented to modify the speed and torque value of a motor, simultaneously increases the torque at the output end when reducing speed. Vice versa, when it increases speed, it reduces torque.
Understanding the basic differences between gear designs, the fundamentals, and how to match gearboxes with your project demands are 3 crucial dimensions in choosing the right gearbox for your electric motor.
Two main types of gearboxes are in-line gearboxes and right-angled gearboxes, each employing specific types of gear.
In-line gearboxes can have the output shaft either coaxial (aligned) with the motor shaft or offset by a small distance, depending on the design of the gear train. Gears such as spur gears, helical gears, herringbone gears, and planetary gears are commonly used in in-line gearboxes to transmit the RPM of the motor to an output shaft parallel to the motor shaft.
In contrast, right-angle gearboxes transfer the RPM of a motor to an output shaft at right angles (90 degrees) from the motor shaft axis. Gears like bevel gears and worm gears are typically installed in right-angle gearboxes.
To shoulder every possible task in lifting and driving mechanisms, Purui imported NILES gear grinding machines, AICHELIN heat treatment systems, MAZAK machining center, and many big-name production equipments, resulting in a series of gearboxes with high precision, low energy consumption, low noise, and long lifespan.
