Correct use and maintenance it is often encountered. In all kinds of mechanical equipment, the installation of ball screw, must pay attention to the following matters:
1, The ball screw is precision transmission device, must be lubricated. Recommend the use of potassium soap grease and 1 ~ 3 turbine oil lubrication in the nuts.
2, The ball screw like the rolling bearing, mixed with dust and foreign matter, will reduce the service life. Therefore, must use the screw protective cover to protect. At home and abroad all kinds of ball screw most parts have been equipped with a labyrinth seal ring, to prevent dirt from entering the ball screw body. In addition, use in the places of metal filing easily enter screw, should also consider the use of screw protective cover in the screw length protection.
3, Because of the special structure of the ball screw nut, should not bear radial load, in order to avoid screw bending, affect the transmission accuracy and flexibility of movement, reducing service life. Therefore, when installed, with particular attention to the axial lead of the screw and nut seat moving trajectory of the parallel, and the central axis of the screw bearing should be consistent with the central axis of the nut seat.
4, The screw is installed on the device, be careful not to separate the screw and nut, to avoid ball prolapse. Do not knock the ball screw in installation, with particular attention to the protection of the ball catheter, because of its thin wall, collision deformation will make the ball flow restriction.
