升降机厂家http://www.jntr168.com/介绍随着机械产品日趋高速化、多样化，对作为重要机械旋转件的滚动轴承要求也愈来愈高，为进一步提高滚动轴承在升降机上的应用水平，人们对运转中轴承因负荷不同、滚动体与滚道之间产生滑动而造成擦伤的原因越来越重视。尤其是在升降机械装配时，应根据轴承的使用情况，对轴承的预紧负荷力的大小进行选择，以优化轴承的游隙。
Lift manufacturers introduced products with increasingly high-speed machinery, diversified, of an important piece of Rolling mechanical rotation requires higher and higher, in order to further improve the application of the rolling bearing on the elevator level, people running in different load bearing due to rolling slippage between the body and the raceway and causes abrasions of more attention. Especially when lifting machinery assembly, should be based on the use of bearing preload to the size of the load bearing force can be selected to optimize the bearing clearance.

升降机厂家分析滚动轴承的游隙分径向游隙产和轴向游隙产两种，它们分别表示轴承内外圈，沿径向或轴向的最大相对位移量。轴承标准中将径向游隙分为基本游隙组和辅助游隙组，应优先选用基本游隙组，轴向游隙可由径向游隙按一 定的关系换算得到。对内外套圈可分离的轴承，其游隙须由安装确定。
Lift manufacturers analysis of rolling bearing clearance radial clearance capacity points and two axial clearance capacity, which represent the bearing inner ring, a radial or axial maximum amount of relative displacement. Standard radial clearance in the bearing clearance group is divided into basic and secondary clearance group, preference should be given basic clearance group, axial clearance radial clearance by a certain relationship Converted. Separable inner and outer rings of the bearings, the clearance shall be installed OK.

升降机厂家http://www.jntr168.com/谈到在无负荷的情况下，轴承内、外滚道间所能移动的最大距离即为轴承的游隙，在大多数情况下，滚动轴承在工作过程中应允许有适当的游隙，游隙过大，同时承受载荷的滚动体数目减少，易使滚动体与套圈产生弹性变形，降低轴承寿命和旋转精度，产生径向跳动，从而引起振动和噪声；游隙过小，则工作时阻力增大，轴承容易磨损，寿命缩短。
Lift manufacturers Speaking at no load, the bearing, the maximum distance between the outer race track can move is bearing clearance, in most cases, the rolling bearing during operation should allow adequate clearance, clearance is too large, while reducing the number of rolling elements bear the load, easy to make rolling ring elastically deformed, reduce bearing life and rotational accuracy, radial runout, causing vibration and noise; clearance is too small, the work when the resistance increases, the bearing is easy to wear and shortened life expectancy.
