The ball of the universal milling and lifting platform rolls off, how to install,
Screw pair after repair good, reinstall the screw pair, need to find a good accuracy of each connecting parts, including position accuracy, positioning accuracy, etc., such as straightness, coaxial degree, parallel degree, diameter jumped, end or something. This is easy to say, but it takes care and patience to do it, and it is usually done by experienced machinery-fitter or fitter. If you can't do it, call the line cutting manufacturer and ask them to repair it.
Remove the screw and remove the poles, bearings, and bearings. Find a root (casing pipe diameter and the bottom of the screw thread diameter size, casing Canon and screw axis diameter size), the sleeves on the screw axis, the screw nut screw on the casing; When fully rotating to the casing, remove the casing and the screw nut. Slide to one end of the casing and the screw nut expose about half a circle ball nut (must pay attention to, don't put the ball, or ball will all fall out), with tiny rod or wire, adjust the position of the ball, with one or more of the position of the ball, then fill in falling ball (this step is very important, it is better to have a ball screw pair assembly experience to do); Once you have finished, put the casing on the shaft of the screw. Then turn the nut onto the screw.
Ha ha, use dry oil stick ball into the channel of nut, and then rotate, but make it sound so simple, but to operate because you are not professional to do this, also pretty difficult. First, look at the inner circle of the screw and the outer circulation, and the ball is not in the position of the channel. It is usually necessary to rotate on the screw to prevent the ball from falling.
Screw has a variety of forms, one of the most common is to use return and return two catheters, if not nut screw the screw will not drop the ball, if there is no turn the screw nut and fell out of the ball, that is to return or return pipe is broken, have to put on reload. Let me be specific. If there is no damage, then use the lithium base grease to keep the ball rolling in separate loops, and then turn the nut back in the way of the regular nut. The key is to start at the beginning, but once the ball comes out, it's going to come back again. Try it twice. (note the non-circular path (snails) don't let the ball drop!)
