Dispatch of net of machine tool of Chinese numerical control: As the wide application of machine tool of our country numerical control and other automation equipment, the ball guide screw that serves as efficient and energy-saving, accurate drive deputy use increasing also. Use correctly reach maintain it also is the thing that often encounters. In all sorts of mechanical equipment, installation ball guide screw deputy, must notice the following item: (１ ) ball guide screw belongs to accurate gearing, must undertake lubricating. Use Potassium is recommended inside nut black radical grease and １ ～ 3 turbine are oil-lubricated. (2) ball guide screw and scroll bearing are same, interfuse dirt eyewinker, will lower service life. Accordingly, must use guide screw to protect jacket to try to protect. Guide screw of domestic and international of all kinds ball deputy much already all contained labyrinth seal ring, prevent dirty content to enter system of ball guide screw inside. Additional, when the place of guide screw of metallic bits easy immerge is used, still should consider to go up endlong in guide screw use guide screw protection to cover defend. (3) the special structure as a result of nut of ball guide screw, unfavorable bear radial load, lest cause guide screw to bend, affect the flexibility of transmission precision and motion, lower service life. When reason is installed, the axes line that should note guide screw especially and nut the parallel of mobile contrail, make axes of center of guide screw bearing should with nut central axes is consistent. (4) get on guide screw installation at equipment, the attention cannot make guide screw and nut detached, lest ball emergence. Ball guide screw is not beaten when installation deputy, notice to protect ball vessel especially, because its tube wall is thinner, collision is out of shape will make steel ball flow is controlled about.
