The torque adjustment coupling as shown in Fig. connects the two shafts into one axle. The ends of the axle are connected with two pinions. The torque in the gear test equipment may be adjusted by shifting the relative phase of the elements in the coupling.The advantage of utilizing this coupling is explained in details as follows.In conventional gear test experiment, the torque on gears is given by external loading,such as a magnetic brake. In that method, the motor has to be carefully controlled for di
The torque loading does not change once the two pieces of the torque adjustment coupling is frmly locked. The torque is locked in the shaft loop, and keeps constant for any motor speeds. This arrangement does not need any external load and reduces the complexity of designing the driving system. It has been the most reliable approach for investigating and testing a gear system.求解释这里所说的转矩加载没咋看懂
