The Difference Between the Gear Reducer and Other Reducers

The reducer is generally used for transmission equipment with low speed and high torque. The motor, internal combustion engine or other power running at high speed achieves the purpose of deceleration through the gear with few teeth on the input shaft and the large gear on the output shaft meshing with the reducer. Ordinary reducers also have several pairs of gears to achieve the ideal deceleration effect on the same principle.

The characteristics of the gear reducer are: it can perform power splitting when transmitting power; at the same time, its input shaft and output shaft have coaxiality, that is, the output shaft and input shaft are set on the same main axis. Therefore, gear reducer transmission has been used by people to replace ordinary gear transmission, and as a speed increaser and speed change device in various mechanical transmission systems.

The reducer is relatively large and can realize the synthesis and decomposition of motion. As long as the type of gear transmission and the gear matching scheme are selected correctly, several gears can be used to obtain a large transmission ratio. The gear reducer transmission is only used to transmit motion, and its transmission ratio can reach several thousand. It should be pointed out that when the transmission ratio is large, the gear transmission can still maintain the advantages of compact structure, small mass, and small volume. In addition, it can also realize the synthesis and decomposition of motion, and realize complex motion with various speed changes.

gear motor

As we all know, the gear reducer is an electromagnetic device, and the gear reducer converts or transmits electrical energy according to the law of electromagnetic induction. Electric motors (also called electric motors), use the letter “m” in the circuit (or “d” in Japanese standards). Its main function is to generate driving torque as a power source for electrical appliances or various machines. A generator is indicated by the letter “g” in the circuit. The main function of the gear reducer is to convert the mechanical energy into electrical energy. At present, it is more commonly used to use heat and water to drive the generator rotor to generate electricity. The reducer is a power transmission mechanism that uses a gear transmission to reduce the number of rotations of the motor (motor) to the required number of rotations and obtain a larger torque. Gear reduction needs to be a combination of motor, reducer and two-in-one. It is the integration of the reducer and the motor. As you can see, the gear reducer uses a set of different numbers of wheels to reduce the output shaft speed of the motor to the required speed. The gear reducer can be used together with the rotary encoder.

This whole can also be called a gear motor or a gear motor. It is usually assembled and supplied by a professional reducer manufacturer. The geared motor is widely used in steel, machinery and other industries. The advantage of using a geared motor is to simplify the design and save space.

The gear reducer has small volume, small mass, compact structure and large bearing capacity. Because the gear transmission has power splitting, the center wheel forms a coaxial transmission, and the internal meshing gear pair is reasonably used, the gear transmission structure can be very compact. In addition, since the wheels are evenly distributed around the center wheel to share the load, each gear is less loaded and the gears allow for smaller modules.

In addition, this structure makes full use of the large load-bearing capacity of the internal meshing and the allowable volume of the ring gear itself, which is beneficial to reduce the external size, making it small in size, low in mass, very compact in structure, and large in load-carrying capacity. Generally speaking, the overall size and quality of gear transmission are about 1/2~1/5 of that of ordinary gear transmission (that is, under the same load conditions)

The transmission efficiency of the gear reducer is due to the symmetry of the gear transmission structure, that is, it has several evenly distributed wheels, and the reaction forces acting on the center wheel and the bearing of the rotating arm can balance each other, which helps to improve the transmission efficiency. Under the conditions of proper transmission mode selection and reasonable structural layout, the efficiency can reach 0.97~0.99.
