Introduction to the speed test method of rv reducer

　　The rv reducer mainly plays a role in adjusting the speed of the equipment. During the use process, pay attention to the speed test work in time. The purpose of the speed test is to understand whether its running speed is normal. During the entire inspection process Pay attention to the correct mastery of the test methods. There are two general test methods, namely the Hall effect principle speed measurement method and the photoelectric speed measurement method. Let's give you a detailed introduction.
　　(1) Hall effect principle speed measurement method: the motor shaft drives the magnetic steel on the shaft to rotate, thereby changing the size of the magnetic field. The change of the magnetic field is converted into a pulse signal through the Hall circuit, and the rectangular pulse signal is output after amplification and shaping.When the speed changes, the frequency of the output pulse will change.So as to obtain the speed at which the geared motor rotates.
　　(2) Photoelectric speed measurement method: use grid disc and photoelectric gate to form a speed measurement system.When the rv reducer drives the grid disc to rotate through the transmission part, the speed measuring photoelectric gate obtains a series of pulse signals.These pulse signals are coordinated by two timing/counters of the single-chip microcomputer, one for counting and one for timing.Calculate the number of pulses per unit time m, after unit conversion, the speed of the DC motor can be calculated.
　　RV reducer speed calculation formula: r=1000n/(T*N1*N) (rps).
　　r is the speed of the DC motor, N is the number of grids, N1 is the number of interrupts of T1, and T is the timer overflow time of the timer T1.
　　The above two methods can help everyone to test the speed of the rv reducer. In the whole test process, the corresponding processing methods of different methods are not the same. Pay attention to the reduction motor during the test. Do a certain understanding of the operation of the equipment, and then adopt the corresponding test methods to calculate and test its speed. You should always observe whether the equipment is operating normally during the actual test process.
