我国有一些浆丝机的卷取机构采用图一所示的差动行星齿轮机构。齿轮1与摩擦盘相连,动力由 Z3’输入齿轮3与之相连,织轴与系杆 H 一起转动。开始卷绕时,预先根据经丝所需要的张力大小,给制动块以一定的压力 P,使摩擦盘受到一定的阻力矩。织轴由空轴开始卷绕时,经丝张力矩与摩擦盘上的阻力矩相平衡,这时摩擦盘静止不动。以后当织轴卷绕直径增大时,经丝的线速度就要变大,但经丝张力矩亦变大。当张力矩超过
Some of our country’s take-up mechanism of the pulp machine uses the differential planetary gear mechanism shown in Figure 1. The gear 1 is connected to the friction plate, the power is connected with Z3 ’input gear 3, and the weaving shaft and the tie rod H rotate together. At the start of winding, the friction plate is subjected to a certain resistance torque with a predetermined pressure P according to the amount of tension required for the warp yarns. When the weaving shaft starts to be wound by an empty shaft, the tension moment of the wire is balanced with the resistance moment of the friction plate, and the friction plate is stationary. When the diameter of the mandrel winding increases later, the linear velocity of the warp should be larger, but the tension moment of the warp also becomes larger. When the tension moment exceeds
