I would like to ask what method installed, do not know how many balls, loaded and loaded less, what is the situation, ah, urgent, thank you
The first floor is right, but this way to operate, few people installed good, there are special tools for ball bearings, if the screw gap, you can replace the ball to repair. LZ I can send you a tool map if necessary. Your points are very attractive - -,
Ball screw generally replace a new, do not change the ball,Especially the replacement of itself, it is difficult to guarantee the accuracy of ball screwsSuggest replacing a new ball screw
A commutator installed in a row, a row can be filled, mainly the size of the ball to be appropriate, the standard ball screw is generally 2 nuts, a nut in general, and 3 commutator, that is, filled with 3 rows of steel balls
[method for installation of ball screws]The ball screw nut pair is only used to bear axial load, the radial force and bending moment will cause the ball screw nut pair additional surface contact stress and other loads, which may lead to permanent damage to the lead screw. Proper installation is the prerequisite for effective maintenance. Therefore, the ball screwWhen the nut is attached to the machine, attention should be paid to the following points:The axis of the screw must be parallel to the axis of the supporting rail. The bearing block and the nut seat at both ends of the machine must be in line at three.Install the nut as close as possible to the support bearing.Install the supporting bearing as close as possible to the nut installation site.When the ball screw is installed on the machine, please do not remove the nut from the lead screw.If you have to remove the use of auxiliary sleeve, or loading and unloading of the ball may fall off. The following points should be noted when handling nuts:The outer diameter of the auxiliary sleeve should be less than the bottom diameter of the screw 0.1-0.2mm.Auxiliary cover in use, must rely on tight screw, screw shaft shoulder.The uninstall, can not be too large, so as not to damage the nut.When loading the installation hole, avoid impact and eccentricity.
