Typically employed in the ball screw nut vice felt ring seal, the thickness of the felt ring is 2 to 3 times the pitch, and the shape of the threaded bore formed so tightly encloses screw and nut or sleeve mount Slots in the tube ends. In addition to using a soft felt seals, but also can be used oil and rubber or nylon material. Because seals and screw direct contact, so the dust is better, but also increases the friction ball screw nut torque. To avoid this friction torque can be used by a hard plastic non-contact labyrinth seals, made the hole and screw thread rolling road opposite shape and leave some gaps. Shandong Bot precision ball screw installed radial force on the role of Vice ball screw, ball screw moment will produce additional surface contact stress load, can exacerbate the ball screw nut and screw between friction, reducing its life, it may cause permanent damage to the screw. Therefore, when you install the ball screw ball screw Lishui supply, should note the following: must be parallel to (1) the screw axis and the accompanying guide axis, parallel error ≤0.05mm Quzhou Ball Enterprises machine supported at both ends of the ball screw and nut bearing housing bore hole center center, three points must be in a line. (2) When the ball screw nut and nut seat be installed on the machine Quzhou Ball price should be close to the end of ball screw support bearings. Using integrated installation (3) Generally, do not remove the nut from the screw to. Under special circumstances ball screw nut must be removed, you must use an auxiliary axis ball screw disassemble, or otherwise uninstall the ball easily scattered.
