The invention relates to an axial force limiting retaining device and method, and is characterized in that the axial force limiting retaining device comprises an acting rod (1) for transmitting acting force, a fixing element (3), a first adjusting screw plug (2), a first disc spring group (4), a first guide rod (5), a second guide rod (7), an extrusion column (6), a second disc spring group (8), a second adjusting screw plug (9), the second guide rod (7), the first guide rod (5), the second disc spring group (8) and the first disc spring group (4), the second adjusting screw plug (9) and the first adjusting screw plug (2) are respectively and symmetrically arranged with the extrusion column (6); the head of the trailable column (6) is provided with a trapezoidal protrusion, the angle and the size of the trapezoid are consistent with those of the trapezoidal groove, and the tail of the trailable column (6) is provided with two symmetrical slopes. The method is simple in structure and high in reliability, so that the maximum limiting force of the rod piece can be kept under the condition that the device is not damaged, the problem of alternating fatigue fracture of the device is avoided, the reliability of equipment is improved, and the driving efficiency is improved.
本发明是关于一种轴向限力保持装置及方法,其特征是:包括:用于传递作用力动作杆(1)、固定元件(3),第一调节螺堵(2)、第一碟簧组(4)、第一导杆(5)、第二导杆(7)、挤脱柱(6)、第二碟簧组(8)、第二调节螺堵(9),第二导杆(7)和第一导杆(5),第二碟簧组(8)和第一碟簧组(4),第二调节螺堵(9)和第一调节螺堵(2)分别与挤脱柱(6)对称安装;挤脱柱(6)头部设置梯形凸起,梯形的角度和大小与梯形槽一致,挤脱柱(6)的尾部设置两个对称的斜面。这种方法结构简单,可靠性高,以便在器件不破坏的情况下能保持杆件的最大限力,避免器件的交变疲劳断裂问题,提高设备的可靠性,提高行车效率。
