The geared high torque AC motor is an integrated body of the high torque gearbox and the high torque AC motor (high torque AC motor). This type of integrated body is also commonly referred to as a gear reduction high torque AC motor or a geared high torque AC motor, and is usually assembled and assembled by a professional high torque gearbox manufacturer. The deceleration high torque AC motor is widely used in the steel industry and the machinery industry. The advantage of the micro-reduction high torque AC motor popular in the 21st century is to simplify the design and save space, while the power and reduction ratio and torque are not reduced. The geared high torque AC motor generally achieves a torque reduction effect by combining a high torque AC motor, an internal combustion engine, or other high-speed power equipment through gears of different sizes inside the reduction high torque AC motor.

To determine the model number of a geared high torque AC motor, you need to determine the following parameters:
1. Determine the running speed of the machine, and calculate the reduction ratio of the gear reduction high torque AC motor based on this speed (reduction ratio = input shaft speed / output shaft speed = high torque AC motor speed / mechanical required speed);
2. Calculate the torque of the load, select the output of the gear reduction high torque AC motor according to this torque (refer to the “output torque meter” provided by the gear reduction high torque AC motor manufacturer), and determine the model of the gear reduction high torque AC motor;
3. Determine the additional functions of the geared high torque AC motor, such as power-off brake, energized brake, frequency conversion, shrink frame, shell material, etc. Some additional functions can only be provided by specific factories, so when selecting, the communication with the supplier is very important.
The application of the geared high torque AC motor is very extensive, and it is an indispensable power equipment for mechanical equipment, especially in packaging machinery, printing machinery, corrugated machinery, color box machinery, conveying machinery, food machinery, three-dimensional parking equipment, automatic storage, three-dimensional warehouse, Chemical, textile, dyeing and finishing equipment.
The piv gear main features of the piv motor reducer drive are china gear reducer as follows.
1. The ability supplier gearbox motor to move smoothly, resist shock and vibration. Because several piv motors with the same structure are used, they are evenly distributed around the center wheel, so that the forces of the piv motor and the rotating arm can balance each other. At the same time, the coaxial china geared motor also increases the number of teeth involved in the meshing, so the piv motor transmission has a smooth movement, piv spare parts strong resistance to shock and vibration, and reliable work.
2, the transmission gear motor china is relatively large, can achieve the synthesis and decomposition of motion. As long as the type of piv motor transmission and the matching gear scheme are properly selected, a large number of gears can be used to obtain a large transmission ratio. In a piv motor reducer transmission that acts only as a transmission motion, the gear ratio can reach several thousand. It should be pointed out that the piv motor transmission can still maintain many advantages such as compact structure, small mass and small volume when its gear ratio is large. Moreover, it can also realize the synthesis and decomposition of motion and the complex movements that realize various shifting.
3. The piv motor reducer is small in size, small in mass, compact in structure and large in carrying capacity. Because the piv motor transmission has power splitting and the central wheel constitutes a coaxial transmission and the internal gear pair is properly applied, the structure can be very compact. Then, due to the uniform distribution of several planet wheels around the center wheel to share the load, each gear is subjected to less load and allows the gears to adopt a smaller modulus. For the gearbox reducer ,In addition, the coaxial reducer fully utilizes the internal bearing capacity and the capacity of the ring gear itself, which is beneficial to reduce the size of the outer casing, making it small in size, small in mass, compact in structure, and capable of carrying. Big. In general, the size and mass of the piv motor transmission are about 1/2 to 1/5 of the ordinary gear transmission (that is, under the same load conditions).
4, piv motor reducer transmission efficiency is with high quality piv gearbox manufacturers the symmetry of the piv motor transmission structure, that is, it has a number of evenly distributed piv motors, so that the reaction forces acting on the center wheel and the arm bearing can balance each other, which is beneficial to achieve Improve the efficiency of the transmission. When the transmission electric motor gear reducer type is properly selected and the structure is arranged reasonably, the efficiency value can reach 0.97~0.99.
The reducer is a mechanical necessity that can change the speed and output torque. As an important part of the mechanical transmission system, the reducer can now be seen in all kinds of machinery, transportation, construction, machining and other fields. So, what are the benefits of using the reducer
1. The use of the reducer can effectively maintain the function of the motor. During operation, the reducer receives large torque. When it is overloaded, it is transmitted to the motor as long as the overload is divided by the reduction ratio!
2. Save the use cost. If the motor is directly responsible, it may cause damage to the motor. When the overload is very large, the deceleration time is damaged first, and the reducer can be restored to use only by changing the spare parts. The cost is relatively low. If the motor is directly damaged, the maintenance is relatively slow, and the cost is also high.
3. Effectively reduce the moment of inertia, and the reducer can timely control the start stop and speed change. Increasing the torque through the reducer is equivalent to increasing the input power, which can reduce the power required by the input motor (in the place where speed regulation is required). Generally, the motor is more expensive than the reducer, so it is considered to use the reducer.
4. It can effectively save energy and reduce the output torque current of motor by using reducer.
5. Using the reducer can effectively reduce the motor speed and increase the torque, and output the corresponding multiply/decelerate ratio according to the motor.
6. Effectively reduce the load inertia of the motor. In numerical terms, the inertia is the square value of the reduction ratio. Different motor inertia values are different.
Installation arrangement
The reduction motor is characterized by high efficiency and reliability, long working life, simple maintenance, wide application, etc. Its stages can be divided into single-stage, two-stage and three-stage gear reduction motors, and the installation layout mainly includes deployable, coaxial and shunt type.
1. In the deployable type of two-stage cylindrical reduction motor, the gear is asymmetric relative to the supporting position. When the shaft produces bending and torsion deformation, the load is distributed unevenly in the tooth width. Therefore, the shaft should be designed with greater stiffness, and the gear should be far away from the input end or output end.
2. The characteristics of the split flow type of the two-stage cylindrical reduction motor: the extended shaft position of the split flow type reduction motor can be extended from either side, which is convenient for the overall configuration of the machine. The gears of the split flow stage are all processed into helical teeth, rotating right and left at the same time to offset the axial force. One of the shafts shall be able to move a little axially to avoid jamming the gear.
3. Features of coaxial reduction motor: the radial dimension is compact, but the axial dimension is large. As the intermediate shaft is large, the shaft will distort greatly under load, so the load concentration along the tooth width is serious. At the same time, because the centers of the two gears must be consistent, it is difficult to make full use of the bearing capacity of the high-speed gear, and it is also difficult to lubricate the bearing located in the middle part of the reduction motor. The input end and output end of the reduction motor are located at both ends of the same axis, which limits the overall configuration of the transmission device.
