小型开式压力机的滑块一般都没有平衡装置,以前人们常选用经常作用式的制动器来防止滑块的导前,由于这种制动器的制动力矩在整个工作循环中保持不变,所以能量损失大。当采用偏心轮带式制动器时,虽然滑块到达下死点制动器不完全松开,但这时制动力矩已比 Small open presses generally do not have the balance of the slider, often used in the past often use the brake to prevent the slider before the guide, because this brake braking torque throughout the work cycle remains unchanged, so the energy Great loss. When using the eccentric belt brake, although the slider reaches the bottom dead center brake is not fully released, but then the braking torque than the
