Information

Micro gear motor refers to the integration of reducer and motor, also known as gear motor or gear motor, which is widely used in steel, machinery, construction and other industries. Next, we will introduce the common types of micro geared motors.

1. The main feature of the worm gear reducer is the reverse self-locking function, which can have a large reduction ratio. The input shaft and output shaft are not on the same axis or plane. However, it is usually bulky and has low transmission efficiency and accuracy.

2. Harmonic harmonic drive miniature deceleration motor utilizes the controllable elastic deformation of flexible elements to transmit motion and power, with small size and high precision. But the disadvantage is that the life of the flexible wheel is limited, it is not resistant to impact, and its rigidity is worse than that of metal parts. The input speed cannot be too high.

3. Planet miniature gear motor has the advantages of compact structure, small return clearance, high precision, long service life and large rated output torque. But the price is a bit expensive. Geared motors are generally used for low-speed and high-torque transmission equipment. By meshing the gears with fewer teeth on the input shaft of the geared motor with the large gears on the output shaft, the power of motors, internal combustion engines or other high-speed operations is reduced. Ordinary geared motors will also have several pairs of gears with the same principle to achieve the desired deceleration effect. The gear ratio of large and small gears, that is, the purpose of the transmission ratio reduction box (or gearbox), includes: (1) acceleration and deceleration, that is, the speed change gearbox (2) changing the driving direction. For example, we can change the rotational torque by using two sector gears to transmit the force vertically to another rotating shaft (3). Under the same power conditions, the faster the gear rotates, the less torque is on the shaft, and vice versa. (4) Clutch function: We can separate the engine and the load by separating the two gears that are initially engaged. Such as brake clutch etc. (5). For example, we can use one engine to drive multiple slave shafts through the main shaft of the gearbox, so as to realize the function of one engine driving multiple loads.
