Answer
When a wave spring is used in a housing made of a relatively soft material like aluminum (e.g., 6061-T6), the concentrated loads at the wave crests can cause 'brinelling' or localized indentation. This increases the effective work height and reduces the spring preload over time. ដើម្បីបងា្ករបញ្ហានេះឧបករណ៍លាងដែករឹង (ជាទូទៅ RC 40-45) ត្រូវបានដាក់នៅចន្លោះនិទាឃរដូវនិងផ្ទៃអាលុយមីញ៉ូម។ The washer distributes the load over a larger area. កម្រាស់របស់ម៉ាស៊ីនបោកគក់ត្រូវតែគណនាក្នុងការគណនាកម្ពស់សរុប៖ $H_{total} = H_{spring} + t_{washer}$ ។ In high-vibration automotive environments, this is a standard practice to prevent wear-induced loss of tension in belt tensioners or clutch packs.
