〔産業上の利用分野〕

て使用している。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the improvement of springs that require characteristics in which the spring reaction force changes little with respect to the amount of deflection near the point of use (hereinafter referred to as constant load characteristics). [Technology] For example, in a tool clamp for a machining center, in order to firmly hold a tool, disc springs having a predetermined spring reaction force and deflection amount are stacked one on top of the other in a limited space.

ようにふち部を設けることにより、使用点付近で略コン
スタントロード特性を付加した事を特徴とする。However, with disc springs, the change in spring reaction force relative to the amount of deflection is large, and in order to obtain the amount of deflection required to remove a tool held by a predetermined spring reaction force, it takes a much larger amount of deflection than when clamping.
It was necessary to apply a load [Means for solving the problem] The present invention is made as follows in order to solve the above problem. In other words, in a disk-shaped or dish-shaped leaf spring with a hole, a rim is provided on either the inner circumference or the outer circumference, or both, so that the edge is bent uniformly in the axial direction over the entire circumference. It is characterized by the addition of almost constant load characteristics near the point of use.

上記のことから内周、外周のふち部の長さを変えること
により、容易にばね反力を増減させることもできる。When a load is applied to the flat cup spring according to the present invention in the axial direction, the bending portions of the inner circumference and outer circumference have strong rigidity, so the initial elastic deformation is caused by the tip of the edge 4 on the inner circumference shown in FIG. The spring reaction force is generated in the direction in which the diameter becomes smaller, and the tip of the edge portion 5 on the outer periphery in the direction in which the diameter becomes larger, so that a large spring reaction force can be obtained. However, when further load is applied, the flat portion 6 is elastically deformed in the axial direction.
Since the spring constant becomes small due to the elastic deformation of the flat cup spring of the present invention, it is possible to obtain substantially constant load characteristics after generating a predetermined spring reaction force. Furthermore, from the above, the spring reaction force can be easily increased or decreased by changing the lengths of the inner and outer edges.
