In operation, first fix the gear box, and then connect the gearbox input and output shafts to the spline sleeve of the drive shaft. Turn on the motor control switch (the current meter is in the "off" position). The measured noise is no-load noise. In the process of no-load rotation, the adjusted ammeter is turned to the "on" position. The resulting noise is loading noise. The tests for forward and reverse are performed in the above order. Among them, the telescopic transmission shaft with universal joint can be modified by the transmission shaft of the light truck. According to the telescopic stroke of the required transmission shaft, the transmission shaft is sawn off, one end inner hole is welded with a spline sleeve, and one end inner hole is welded with a spline shaft. (See Figure 1).
If the loading value is relatively strict, the torque sensor and the speed measuring instrument can be used to measure the torque of the magnetic powder brake. Note: The water-cooled magnetic powder brake is water-passed after operation (water pressure 15~30N/cm2).
The test bench has proved by practice that the operation is simple and fast, the accuracy is high, and it is worth promoting.

Hammer Drill, also known as a percussion drill or Impact Drill, is a power Tool used chiefly for drilling in hard materials. It is a type of rotary drill with an impact mechanism that generates a hammering motion. The percussive mechanism provides a rapid succession of short hammer thrusts to pulverize the material to be bored, so as to provide quicker drilling with less effort. If a hammer drill's impact mechanism can be turned off, the tool can be used like a conventional drill to also perform tasks such as screwdriving.
