Answer
많은 조립품에서 하우징과 유지되는 부품의 허용 오차는 웨이브 스프링의 원하는 편향 범위보다 클 수 있습니다. Shim plates (thin, flat washers) are used to adjust the working height $H_w$. If the measured load $P$ is too low, a shim is added to further compress the spring. 관계는 $P_{new} = k(f + t_{shim})$입니다. This is common in high-precision optical mounts where a specific 'feel' or 'torque' is required. Shims also provide a hardened wear surface, preventing the spring from digging into soft housing materials during cycling.
