滚珠丝杠的转动通过螺母使溜板产生直线运动,这是一种常用的传动结构。但是,由于丝杠与导轨间不可避免地存在着平行度误差,传动时容易出现“憋劲”现象,使电机功耗增加。如果丝杠的刚性较高,则情况更为严重,甚至影响传动性能。为此,日本三和工机公司开发了如图所示的浮动螺母。该机构通过板簧使螺母的径向位置处于浮动状态,从而补偿了上述
Rotation of the ball screw through the nut to produce a linear motion slide, which is a common transmission structure. However, due to the inevitable parallelism between the lead screw and the guide rail, the transmission is prone to “bumping” phenomenon, which increases the motor power consumption. If the screw rigidity is higher, the situation is more serious, and even affect the transmission performance. To this end, Japan’s Sanwa Engineering Co., Ltd. has developed a floating nut as shown. The mechanism compensates for the above due to the plate spring which causes the radial position of the nut to float
