Reasons for Non-rebound of the Hammer in Vertical Piano and Solutions: Analysis of Keyboard Height, Lock Bar and Capstan

摘要

立式钢琴弦锤不回弹是常见的机械故障，会严重影响演奏效果。本文通过键盘高度、锁条位置和卡钉状态三个关键参数，深入探讨了弦锤不回弹问题的产生机理，并基于实际维修案例给出了有效的解决对策。通过对击弦机结构的详细探讨，本文旨在为钢琴维护提供理论依据和实践指导，帮助钢琴使用者更好地理解和解决这一问题。此外，本文还特别强调了定期维护和检查的重要性，以预防此类故障的发生，确保钢琴长期保持良好的演奏状态。

Abstract

The non-rebound of the hammer in a vertical piano is a common mechanical malfunction, which severely affects the performance effect. Through three key parameters, namely the height of the keyboard, the position of the lock bar, and the status of the capstan, this paper deeply explores the generation mechanism of the non-rebound problem of the hammer and provides effective solutions based on actual maintenance cases. By elaborating on the structure of the action mechanism, this paper intends to provide theoretical basis and practical guidance for piano maintenance, assisting piano users in better understanding and resolving this issue. In addition, this article particularly emphasizes the importance of regular maintenance and inspections to prevent such malfunctions and ensure that the piano remains in good playing condition over the long term.
