Characteristics and Types of Gear Reducers
April 21, 2021
The gear reducer is a widely used reduction transmission equipment. The main transmission structure integrates the drive motor (motor) and gearbox (reducer). It is also called “gear motor“. The drive motor can adopt DC motor, brushed motor, brushless motor, stepper motor, coreless motor, servo motor, etc. The gearbox reducer can use a planetary gearbox, cylindrical gearbox, parallel-shaft gearbox, worm gearbox, or screw gear. If categorized by the type of drive motor, it can be divided into DC gear motors, stepper gear motors, brushed gear motors, brushless gear motors, coreless gear motors, etc. According to the type of gearbox structure, the reducer can be divided into planetary gear motors, gear reducer, worm gear reducer, parallel gear reducer, screw gear reducer, etc. Different types of gear reducer motors have different applications.
Gear Reducer: The gear reducer uses multi-gear transmission to achieve the purpose of speed reduction. The reducer is composed of various gear trains. For example, a small gear can be used to drive a large gear to achieve a certain reduction. With a multi-stage gear structure, the speed can be greatly reduced. The gear reducer is space-saving, reliable, and durable, and has a high overload capacity, low energy consumption, low vibration, low noise, and good performance. And the reducer efficiency is up to 95%. It adopts high-quality forged steel, rigid cast-iron box body, high-frequency heat treatment on the surface of the gear. Finish machining is used to meet shaft parallelism and positioning bearing requirements. The reducer forming the helical gear transmission assembly is equipped with various types of motors, combined into mechatronics.
Planetary Gear Reducer: The planetary reducer is an industrial product. The planetary reducer is a transmission mechanism. It normally consists of a motor and planetary gear (it is made up of sun gear, planet gears, and a ring gear.). The planet gear relies on the output shaft, the inner gear ring, and the sun gear support. When the input power drives the sun gear, the planetary gear can be driven to rotate and revolve along the center following the trajectory of the inner gear ring. The rotation of the planet gears drives the output shaft connected to the tray to output power. The planetary reducer has the characteristics of small size, lightweight, high carrying capacity, long service life, stable operation, low noise, high output torque, large speed ratio, high efficiency, and safe performance. It features power splitting and multi-tooth meshing. It is a new type of reducer with wide versatility.
DC Reducer: DC reducer motor, or DC gear motor, is an ordinary DC motor combined with a gearbox. The function of the gearbox is to provide lower speed and higher torque. The DC geared motor saves space, and is reliable, can withstand a certain overload capacity, and can meet the power requirements; the DC geared motor has low energy consumption, great performance, small oscillation, low noise, and high energy saving. It uses high-quality forged steel and rigid cast iron. The body and gear surface are heated up and the new type of sealing device has good protection performance and strong adaptability to the environment, which enables the DC gear motor to work continuously in harsh environments such as corrosion and humidity.
Worm Gear Reducer: A worm gear reducer is a power transmission mechanism that uses the gear to reduce the number of revolutions of the motor to the required number of revolutions and obtain a higher torque. Worm gear reducer has a compact mechanical structure, light volume, high efficiency, good heat exchange performance, fast heat dissipation, easy installation, flexible and light, good performance, easy maintenance and repair, stable operation, low noise, durable, strong usability, high safety, and reliability.
