我们在装配有钢球定位的装置(如变速器的拨叉)时,一般用弹簧将钢球压紧在轴的定位槽中实现定位(见图1)。由于钢球装配后要承受弹簧的压紧力,所以,装配时要先将钢球压入槽后再把轴穿入,这样装配相当费力。有时由于其它结构造成空间的限制,无法预先将钢球压下。为此,我们制作了简
When we are equipped with a ball positioning device (such as transmission shift fork), the spring is usually used to press the ball in the positioning groove of the shaft to achieve positioning (see Figure 1). Since the steel ball assembly to withstand the pressure of the spring, so the assembly of the first ball into the slot after the press into the shaft, this assembly is quite laborious. Sometimes due to space constraints caused by other structures, the ball can not be pre-pressed. To this end, we made Jane
