目前C616普通车床输入端的联接传动形式大致可分为刚性传动和弹性传动两大类。图52和53为刚性传动形式。图54、55、56为弹性传动形式。图52、53两类刚性传动弊病较多。目前C616车床是采用电动机直接启动的正、反转机构。这种机构虽然简单,操作方便,但在启动和运转中突然反转时有很大的冲击力(即使在控制电路中有时间继电器,使之有一点停转时间)。因为电机除作为动力源还兼负主运动的换向及制动。当主运动正向运转需要快速停车时,电机断电,由于在一定
At present, C616 common lathe input coupling transmission can be divided into rigid transmission and flexible transmission two broad categories. Figures 52 and 53 are rigid transmissions. Figure 54,55,56 for the flexible transmission. Figure 52, 53 two types of rigid transmission more ills. The current C616 lathe is the direct use of the motor to start the positive and reverse body. Although simple and easy to operate, this mechanism can have a significant impact on sudden reversals during start-up and operation (even with time relay in the control circuit to allow for a little stall time). Because the motor in addition to as a power source also has the main movement of the commutation and braking. When the main movement of the forward running fast parking, the motor power, due to a certain
