通常,人们在处理拧断或是由于其他原因而损坏的钢琴弦轴时,是把残留在轴孔内的一段弦轴用力向下敲入弦轴板枕木中。很明显,这种处理方法有两个害处:其一,因弦轴是圆头的,敲入时阻力很大,容易使枕木产生裂纹;其二,敲入时震动大,势必对其他弦轴与轴孔的配合施加破坏性影响,严重者会发生松动。 Normally, when dealing with a piano string screwed off or damaged for other reasons, a string of string pegs remaining in the shaft hole is forced down into the pegboard. Obviously, this approach has two disadvantages: First, because the string axis is a round head, when knocked into a large resistance, easy to make the sleepers crack; Second, the knocking vibration, it is bound to other string axis With the cooperation of the shaft hole to exert devastating effects, severe cases will occur loose.
