What are the main components of the miniature reduction gearbox?

2020-09-07
Micro reduction gearbox is a commonly used reduction equipment, also referred to as micro reduction motor and reduction gearbox. The diameter of the micro reduction motor in the subdivision field is less than 38mm, the voltage is 24V, the power is less than 50w, and the reduction range is 2 Between -2000; the gearbox materials are made of metal and plastic respectively; parameters, power, and performance are customized according to the needs of the application field. The commonly used micro-motor reduction gearboxes currently mainly include gear reducers, planetary reducers, and DC reducers , Hollow cup reducer, which will be introduced in turn below.

1. Miniature reduction gearbox
The micro gear reducer motor is a micro motor drive closed transmission reduction device (also known as a micro gear reduction motor), which is a combination of a reducer and a motor (or motor), used to reduce the speed and increase the torque to meet the work of mechanical equipment Needs. And this combination can also be called a gear reducer or a gear reducer motor. Generally speaking, the miniature geared motors are assembled and supplied as a set by the geared motor manufacturer. If the two parts are purchased separately, the combination will be greatly damaged.

2. Miniature hollow cup reduction gearbox
The structure of the miniature hollow-cup motor adopts the rotor structure of a traditional motor, and uses an iron-core rotor, also called a hollow-cup rotor. This novel rotor structure eliminates the power loss caused by the formation of eddy currents in the iron core. At the same time, its weight and moment of inertia are greatly reduced, thereby reducing the mechanical energy loss of the rotor itself. Due to the structural change of the rotor, the operating characteristics of the motor have been greatly improved. It not only has outstanding energy-saving characteristics, but more importantly, it has the control and drag characteristics that cannot be achieved by iron core motors.
 
3. Miniature planetary reduction gearbox
Compared with other reducers, the miniature planetary reducer has rigidity and high precision. Most of them are installed on stepper motors, servo motors, and DC motors to reduce speed, increase torque, and match inertia.

4. Mini DC reduction gearbox
The miniature DC reduction motor, that is, the miniature gear reduction motor, is based on an ordinary DC motor, assembled with a miniature gear reduction box. The function of the gear reducer is to provide a lower speed and a larger torque. At the same time, different reduction ratios of the gearbox can provide different speeds and torques. Generally, different industries use DC gear motors of different powers, and custom power design modes are generally adopted.
