Abstract: A coil spring reduces Hertzian stress on a first turn and bending stress on a coil end. A coil end 11 is shifted in a diametral outer or inner direction of a coil spring relative to the first turn 13, to form a vertical gap between the coil end 11 and the first turn 13 in a free state without load on the coil spring. Due to the gap, the coil spring including the coil end 11 and first turn 13 can be entirely processed by shot peening as well as the remaining portion. The first turn 13 receives a combination of torsional stress and Hertzian stress (contact stress). Since the coil end 11 that receives high Hertzian stress is shifted in a diametral outer or inner direction of the coil spring relative to the first turn 13, a contact point on the first turn 13 is shifted in the diametral outer or inner direction to reduce the torsional stress on the first turn 13.

Abstract: A mechanism for converting the force from a linear extension spring into a constant force. A cable, connected to the spring, rides in a variable radius input pulley groove. A second cable rides in a variable radius output pulley groove. The dual pulley mechanism is smaller than previous spiral pulley mechanisms. The output force and stroke is a function of the sizes of both pulleys. A standardized design enables a small number of input and output pulleys to cover a large range of applications. An end plug in a helical spring can be used to make fine adjustments to the output force. The pulleys can be accurately phased relative to each other with a spline mechanism. The pulley grooves may lie in a plane, or they may advance in an axial direction as the pulley rotates. By continuously varying the rate of axial advance, the tangent to the groove can be aimed or focused at an external point. The focused groove reduces cable friction and wear.
