How does the speed reduction motor work?

A speed reducer motor is generally an ordinary DC motor with a gear reducer just in front of the ordinary motor. Reduction gears are generally used for low-speed, high-torque transmission equipment, putting electric motors. Internal combustion engine or other high-speed power through the input shaft of the gear reducer gears with fewer teeth mesh with the output shaft of the large gear to achieve the purpose of deceleration, ordinary reducer will also have several pairs of the same principle gear to achieve the desired deceleration effect, the ratio of the number of teeth of the large and small gears, is the transmission ratio.

Connection of reducer and motor

Motor, gearbox can be used with the transmission through the gear wheel system. First of all, you should select the appropriate power supply according to the working voltage of the motor, and then find out the required transmission ratio according to the speed you need and the motor speed, and then determine the transmission ratio of the wheel system according to the transmission ratio that the existing gearbox can provide. Finally, according to this ratio to determine the ratio of the number of gear teeth, and then through mechanical analysis to select the appropriate gear radius, gear material. Finally, the gears are machined, assembled and debugged correctly, and then ready for use. Specific operation steps: 1, according to the parameters of the working machinery to calculate the required torque, speed, and calculate an approximate power. 2、Check the rated torque of the motor according to the power, and the maximum torque of the motor according to the speed 1450 rpm. 3, according to the required torque / motor rated torque, that is, the reduction ratio of the reducer. At this point has not been finally selected, check whether the speed at this reduction ratio meets the need. If it is larger than the required speed, it meets the requirements; if the speed is too small, the required reduction ratio is calculated according to the speed. In fact, to put it bluntly, it is the speed, torque, power three parameters to play around, take one of the calculation, and then the other accounting can be. 4、There are many types of reducers, choose the type as required. 5, pay attention to the protection of the reducer, the choice of reducer, its parameters speed, transmission ratio behind a power, is the maximum power allowed reducer, can not exceed, otherwise it may lead to damage to the reducer overload. 6, reducer according to the use of working conditions have a lot of safety factors, if not skilled, you calculate the required parameters, choose a large gear reducer can be.

How to match the motor with the reducer

Motor and reducer matching must be power matching. Can not be small with large, let alone large with small. The power of the motor we can see through the nameplate, must first set the parameters of the reducer (speed, torque, etc.), and then match the appropriate motor according to the parameters of the reducer. Two since the program, first, the calculation, based on the output shaft torque value, the output shaft speed, calculate the output power, and then this value should be multiplied by 1.2, which is called the power margin. Another way is very simple, directly ask the sales of reducer staff: their own reducer should be matched with how big motor. This is a standardized configuration, the manufacturer's design engineers are more professional. If the reducer power and motor power is not the same, overload motor output torque of at least 2 times the rated torque, the reducer is prone to damage. So choose unless there is a reliable protection measures, or to ensure that there is never overload working conditions. The reducer is connected to the motor when working directly on the work machine spindle, when the reducer is running, the counter torque acting on the box, and the counter torque bracket installed on the box or by other methods to balance, directly matched, the other end is connected to the fixed bracket. The motor is matched with the reducer to make it run better and improve the efficiency at the same time. When matching the motor to the reducer, be sure to follow the correct method, or directly to the manufacturer or sales staff to match, so that it is easier to make the correct judgment

What is the reason for the speed reducer motor adapter and the speed reducer not turning?

What is the reason why the reducer motor adapter and reducer do not turn? In the process of gear reducer or worm gear reducer selection, the power of the motor is too small, and the reducer is too large in the case of the reducer can not take the motor situation. In addition, there is another situation is a fault will also appear when the reducer can not run, commonly known as a stuck. There is a moment to join the load is too large, then the reducer can not drive the operation, so there will be a momentary motor can not carry the load, which can easily lead to motor burnout. There is another is the motor in the open state reducer does not run, which may be the use of blocked motor, the motor will appear at this time this situation

Gear motor governor failure

Gear reducer motor speed control failure, usually the motor itself is damaged. The motor itself contains capacitor, motor, as long as the capacitor is damaged motor does not run, motor internal coil damage motor will not run. 1. gear motor does not run to check the capacitance first, with capacitance table to measure the capacitance of good or bad, if the capacitor is damaged directly replace the same type of capacitor. Because the positive and negative polarity of the capacitor can not be reversed, so use the capacitor without polarity. If the capacitor is damaged, there will be a bump or leakage on the surface.2. If the internal coil of the gear motor fails, you can only repair the motor. In addition, the general small gear reducer motor internal gear oil plastic, gear damage resulting in motor idling, replace the corresponding gear can be. Gear large reducer equipment has a gearbox inside, the need for regular replacement of gearbox oil, otherwise the gears do not get better lubrication leading to abnormal wear.
