The article analyses the working state of turning woodruff key clutch used in presses. When designing a cluth, it proposes, the optimal working angle of the turning key should be decided first, and then, the strength of the turning key be checked, so that the load capacities of the parts of a clutch, i.e, the turning key and the middle sleeve,could be brought into full play. According to the concept that the safe level of the bending strength of the turning key is equal to that of the pressing strength of the...

The article analyses the working state of turning woodruff key clutch used in presses. When designing a cluth, it proposes, the optimal working angle of the turning key should be decided first, and then, the strength of the turning key be checked, so that the load capacities of the parts of a clutch, i.e, the turning key and the middle sleeve,could be brought into full play. According to the concept that the safe level of the bending strength of the turning key is equal to that of the pressing strength of the middle sleeve, the theoretical formulation and the graphic method of deciding the optimal working angle of the turning key are deduced. The article points out that the working angle of the turning key in the existing presses is too big and that if the working angle of the turning key is decreased from 45° to 28°--31°, we can bring the load capacity of the clutch into full play, decrease the bending deformation of the turning key, and raise the uniformity of pressing stress as well. The article also points out that the braking angle of the existing woodruff turning key clutch is very small, which is unfavourable to the design and the work of a brake. Thus, the main demension of the turning key clutch should be modified in order to improve the working conditions of the brake, and raise the efficiency of the press.

本文分析了压力机半圆形转键离合器的工作情况。提出设计离合器时,应首先确定转键最佳工作转角,再校核转键强度,以便充分发挥离合器主要零件转键与中套的承载能力。按转键弯曲强度裕度和中套的挤压强度裕度相等的概念,推导了确定转键最佳工作转角的理论公式。指出现有压力机转键工作转角若从现在的45°减小到28°—31°,则可充分发挥离合器的承载能力,减小转键的弯曲变形,提高挤压应力的均匀性。并指出现有转键离合器能提供的制动角很小,导至压力机曲轴上允许的制动角仅有1.3°~5.2°,这对制动器设计和工作不利,应修改现有转键离合器的主要尺寸,使离合器能提供较大的制动角,以改善制动器的工作条件,提高压力机的效率。

In this paper, the reliability of cranks was analyzed with static, dynamic reliability theories separately. It was derived that there was a safety working time for cranks in point of fatigue strength. By comparing the difference methods, the conclusion was given that the dynamic reliability analysis was more suitable than the two other method this paper described.
