在滚动式直线导轨中,当循环滚动的钢珠周期性地从非负荷状态滚入负荷状态时,由于负荷量的剧变,往往产生振动,以致影响导轨的传动精度。为了抑制这种振动,日本精工公司(NSN)设计的滚动式直线导轨,在非负荷状态与负荷状态交界处的滚道上,设有很小的倾角,使负荷状态的过渡变得缓慢,避免剧变,有效地抑制了振动。此外,将滚动导轨安装在工作台(或溜板)上时,如果采用4个滚动单元就能大幅度抑制振动。实验证明,采用4个滚动单元时的振幅,为采用单个滚动单
In a rolling linear guideway, when the rolling ball periodically rolls from a non-load state to a load state, vibrations often occur due to drastic changes in the load, so that the precision of the transmission of the guide rail is affected. In order to suppress such vibration, the rolling linear guideway designed by Japan’s Seiko Co., Ltd. (NSN) has a small inclination on the raceway between the non-load state and the load state so as to make the transition of the load state slow and avoid drastic changes , Effectively inhibit the vibration. In addition, when the guide rail is mounted on a table (or slide), vibration can be significantly reduced by using four roller units. Experiments show that the use of 4 rolling unit when the amplitude of a single rolling single
