木工加工滚珠丝杠的特点及注意事项!

来源:www.4066.com 时间:2020-03-09 

  随着我国数控加工技术的发展,滚珠丝杠以其高精度和率的传动优势,逐渐成为数控加工不可缺少的一部分。要保证滚珠丝杠是国外优秀品牌是不可能的,在任何恶劣的环境下都能保证正常使用,木工企业都有扬尘的特点,所以它是滚珠丝杠非正常损坏的高发现象。以下为滚珠丝杠的特点及保养注意事项。
  With the development of CNC machining center technology in China, ball screw has gradually become an indispensable part of CNC machining center because of its high precision and high efficiency transmission advantages. It is impossible to ensure that the ball screw is an excellent foreign brand. It can be used normally in any harsh environment. The woodworking enterprises have the characteristics of dust, so it is a high incidence of abnormal damage of the ball screw. The following are the characteristics and maintenance precautions of ball screw.
  (1)滚珠丝杠属于精密传动装置,必须润滑。油脂不。螺母中建议使用1-3涡轮机油。
  (1) The ball screw belongs to the precision transmission device and must be lubricated. Grease not. 1-3 turbine oil is recommended for nuts.
  (2)滚珠丝杠及滚动轴承,混入异物灰尘会降低使用寿命。因此,必须用丝杠保护套筒来保护。国内外各种类型的滚珠丝杠对大多都安装了迷宫式密封圈,防止赃物进入滚珠丝杠体内。此外,在金属屑容易侵入使用丝杠的场合,还应考虑在丝杠上全长度对丝杠套筒的保护。
  (2) Ball screw and rolling bearing, mixed with foreign dust will reduce the service life. Therefore, it is necessary to protect the sleeve with a lead screw. All kinds of ball screw pairs at home and abroad are equipped with labyrinth seal rings to prevent dirt from entering the ball screw body. In addition, when the metal chips are easy to invade and use the lead screw, the protection of the full length of the lead screw sleeve should also be considered.

  (3)由于滚珠丝杆螺母的特殊结构,不适合承受径向载荷,以免丝杆弯曲,影响传动精度和运动灵活性,降低使用寿命。因此,在安装时,尤其要注意螺杆轴与螺母座的运动轨迹平行,并使螺杆支撑轴与螺母座轴一致。
  (3) Due to the special structure of the ball screw nut, it is not suitable to bear radial load, so as to avoid the bending of the screw rod, affect the transmission accuracy and movement flexibility, and reduce the service life. Therefore, during the installation, pay special attention to the parallel movement track of screw shaft and nut seat, and make the central axis of screw support consistent with the central axis of nut seat.
  (4)在设备上安装丝杠,注意不要将丝杠与螺母分开,以免球脱落。安装时不要磕碰滚珠丝杠副,尤其要注意保护滚珠管,因为其管壁较薄,碰撞变形会使钢球流动受到限制。
  (4) Install the lead screw on the equipment, and pay attention not to separate the lead screw and the nut, so as to prevent the ball from falling off. During installation, do not bump the ball screw pair, especially pay attention to the protection of the ball tube, because the tube wall is thin and the collision deformation will restrict the flow of the ball.
  通过科学、合理的维护可以有效地延长生命周期的滚珠螺杆,有积极影响精密设备的效率,降低螺杆损坏率,减少设备的维修造成的经济损失,延误工作,精度下降,并增加制造商的好处。
  Through scientific and reasonable maintenance, it can effectively extend the life cycle of ball screw, positively affect the efficiency of precision equipment, reduce the screw damage rate, reduce the economic loss caused by equipment maintenance, delay the work, reduce the accuracy, and increase the benefits of manufacturers.
