Gear motors, also known as reducer motors, gear reducer motors, or speed reducers, are the devices in the motion transmission mechanism, which can be usually seen on the inner parts of machines or automotives, etc. As long as there are moving parts on a device, the motion transmission mechanism is required to deliver the energy source of motion from the motor to the moving parts. This results in the need of gear motors, since they ensure the optimal performance of the device as they interact with the connected parts.
In the construction of machinery, gears are categorized in one kind of the most important components. They consist of a circular plate with teeth around the edges, and it is the teeth on each gear that connect with one another that the motion is transmitted. Depending on the different requirements of the transmission or the restriction in the space of forms of the related applications, the gears are designed with various forms, in order to accommodate the different needs of the applications.
No matter what kind of device that contains moving parts in the mechanism, the higher speed isn’t corresponding to the better performance. In other words, in the process of motion transmission from the motor to the moving components, the control of speed is required. At the same time, the strength of the moving parts also determines how well they perform in the mechanism. In other words, in the optimal circumstance, the speed should be properly controlled, and the strength of the moving parts should be remained as high as possible, so as to make the reliable performance of the variety of devices.
In short, what a gear motor does is the tasks that are mentioned above. With the interaction between the gears in a gear motor, the speed of the energy that is transmitted from the motor to the moving parts can be reduced, and the torque, which is how much force provided for driving the moving parts, can be increased.
A gear reducer motor is the combination of a gearbox and an electric motor. Through the connecting shafts that attach the gears and the electric motor through the ports on the gearbox, it makes a motion transmission mechanism. Once the shafts are further connected to the related applications, the transmission tasks are completed.
Considering the load capacity and the required RPM (revolution per minute), the configuration of the gear motors can be divided into the dingle reduction gear and the double reduction gear.
● Single reduction gear
The single reduction gear refers to the only one pair of gears that are contained in the mechanism. A pair of gears consists of one small gear, which is usually called a pinion, and the other large gear. The pinion is connected to the inlet shaft, which is the motor side, and the large gear transmits the energy to the application through the output shaft.
● Double reduction gear
The double reduction gear is used when it is required to reduce relatively high speed of operation. As the name implies, there are two pairs of gears, which conduct two stages of reduction. The pinion is connected to the first reduction gear and the second reduction gear with shafts respectively. After the two stages of reduction, the reduction ratio would be in a larger variation than with the single reduction gear.
Depending on configuration of gears and the shafts in the gearbox, the gear motors can be categorized into two types, including the inline gear motors and the right-angle gear motors.
● Inline gear motors
What makes this type of gear reducer motors called inline can be derived from the arrangement of the components. When looking through the inner part of the gearbox, the shaft helps the motor and the gears align in a row. If the mechanism comes in double reduction gear, the two pairs of gears would also be set parallel to each other.
● Right-angle gear motors
The right-angle gear reducer motor contains two shafts that are perpendicular to each other. Based on the requirements of the applications, there may be either one or two output shafts protrude from the ports of the gearbox. When the motor provides energy through the side of the input shaft, and the gears reduce the speed as well as increase the torque, the energy would be transmitted through the one output or distributed through the applications through the two outputs.
In addition, this type of gear motor is especially suitable for being applied on the corner of the devices, which is perfect for the applications where space is a limitation.
