    • Ball bearing including an outer ring and a sleeve-shaped inner ring which axially is longer than the outer ring. A first rigid washer is secured to either end of the inner ring and the outer periphery of said washer extends radially past the inner periphery of the outer ring. Said washer adjoins the side face of said outer ring and it is supported by said face at heavy axial load. Provided in the space between said inner ring and said outer ring, between the series of balls and each of the rigid washers, are sealing means and protection means.
    • 滚珠轴承包括外圈和轴向上比外圈长的套筒形内圈。 第一刚性垫圈固定到内圈的任一端,并且所述垫圈的外周径向延伸穿过外圈的内周。 所述垫圈邻接所述外圈的侧面,并且在所述面处以重的轴向载荷支撑。 在所述内圈和所述外圈之间的空间中,在所述一系列球和每个所述刚性垫圈之间设置有密封装置和保护装置。

    • Agricultural machine having a frame supported by driving wheels and supporting wheels, said frame having a main part arranged in the longitudinal direction of the machine so as to extend from the region of the driver''s station in the machine, preferably from the upper side thereof, over coupling means for agricultural implements and to a unit including the supporting wheels and coupling means of the machine. Said agricultural machine includes a driver''s station lodged in a cabin immediately before the driving wheel axle. To permit coupling and uncoupling of working implements said agricultural machine is adapted to pivot about the driving wheel axle whereby said machine resting on the driving wheels and on wheels mounted in the free ends of hydraulically operated swinging arms can be run with the supporting wheels lifted up over the working implement which, after the said machine has swung back to normal position, is coupled to the coupling means between the driving wheels and the supporting wheels.
    • 具有由驱动轮和支撑轮支撑的框架的农业机械,所述框架具有沿机器的纵向方向布置的主要部分,以便从机器的驾驶员站的区域,优选地从其上侧延伸出来, 用于农具的联接装置和包括机器的支撑轮和联接装置的单元。 所述农业机械包括一个驾驶员车站,该车站位于驾驶轮轴之前的舱室内。 为了允许工作装置的联接和解耦,所述农业机械适于围绕驱动轮轴枢转,由此所述机器搁置在驱动轮上,并且安装在液压操作的摆动臂的自由端中的轮可以在支撑轮上升的情况下运行 在所述机器已经摆回到正常位置之后的工作器具联接到驱动轮和支撑轮之间的联接装置。
