带座外球面球轴承

带座外球面球轴承 带座外球面球轴承由一个双面密封且外圈具有球形外截面的宽内圈深沟球 轴承和一个轴承座(铸铁座或钢板冲压座)两部分组 成。 Insert ball bearing unit is consisted of a double sealed, single row bearing and one of various types of housings (cast iron or stamping steel housing).2.结构形 式 Bearing units structure 返回 该轴承单元结构紧凑，具有自动调心的功能，安装保养方便，具有完善的 密封装置、密封性能可靠，适应于恶劣的工作环境。广泛应用于农业机械、建 筑机械、纺织机械、食品加工机械及输送带系统等领域。 The outer ring of the selfcontained ball bearing in ground to a sphere, and the bore of housing in machined to a matching radius, This permits self-aligning between the two members. Following figure is a view of a Pillow Black which is the most popular type of Insert Ball Bearing Units with set screw locking. The bearing units have various types of perfect sealing devices and can operate satisfactorily under hard working conditions, especially for machines operated in dustry or muddy surroundings. Thus, they are widely used in agricultural machinery, construction machinery, textile machinery, food stuff machinery and conveying devices, etc. 注:Note:3.产品性能 The features of products 返回?具有自动 调心功能 轴承的外径与轴承座内径为球面配合，两者之间具有自动调心功 能，可补偿因安装误差产生的轴线不重合及安装底面的变 形。 The outside diameter of the self- contained bearing is spherical to match corresponding spherical inside diameter of the housing providing self- aligning between these two members, which compensates for misalignmen of the units resulted from errors in mounting and distorting of thts e foundation. ?负荷能力大 Large load carrying capacity 由于外球面球轴承的内部结构与6200及 6300系列深沟球轴承相同，因而带座外球面球轴承不仅能承受径向负荷，而且 能承受圈套的轴向负荷，同时轴承工作噪音 小。 Being the same as 6200 and 6300 series single row deep groove ball bearings in internal construction of the self- contained bearings, Insert Ball Bearing Units can substain radial loads and substain thrust loads as well. And they are low noise during operating. ?使用寿命长Longer service life 带座外球面球轴承通常使用于诸如泥土、灰尘、潮湿及高温等恶劣的工作 环境，轴承内部的润滑脂在短期内会变质。因而，需要在适当的时间间隔内对 带座外球面球轴承进行注脂重新润滑，用新鲜润滑脂代替已变质的润滑脂。带 铸铁外球面球轴承都带有油嘴，可重新润滑，保证在任何工作环境下具有完美 的性能及长的使用寿 命。 Insert Ball Bearing Units are often used in severe operating conditions where they are exposed to dirts, moisture and high temperature, and in such applications, the grease inside the set-contained bearing deteriorates in a short time. It is required that relubricate the units at suitable intervals so as to replace deteriorating grease with fresh grease. Insert ball bearing units with cast iron housings are all relubricable types equipped with grease fittings to secure full performance and longer service lift of the units under any operating conditions. We can provide several types of sealings as follows: 1.防尘盖与橡胶密封圈组合密封:防尘盖固定在内圈上与内圈一起旋转，橡胶密封圈固定在外圈上，密封胶唇与内圈形成 标准 excel标准偏差excel标准偏差函数exl标准差函数国标检验抽样标准表免费下载红头文件格式标准下载 扭矩接触密封，这种密封能有效地防止外部泥土、灰尘、水气等异物进入轴承内部，同时能阻止轴承内部的润滑脂外漏，使轴承在恶劣的工作环境下也能保持完美的工作性能。如图1。 1.RS+SLINGER type: The SLINGER is fixed to inner ring, rubber seal is fixed to outer ring. The rubber seal and inner ring can form standard torque contact sealing.
