    • The invention provides a new and useful bearing assembly and a spindle utilizing that assembly. The assembly comprising a housing adapted to be secured in a support member, the housing having arranged coaxially therein a cylindrical cavity, a first cylindrical aperture between the cavity and the exterior of a first end of the housing, and an at least partially threaded second cylindrical aperture between the cavity and a second end of the housing, the second aperture being of equal or greater diameter than the cavity; the cavity having arranged therein coaxially therewith, in abutting relation and of outside diameter sufficiently less than the diameter of the cavity to allow sliding movement therein, and in order from the first end, a spacer, a first sealed radial bearing, a second spacer, and a second sealed radial bearing, each of the spacers being of generally cylindrical configuration and of an inside diameter such that the spacers abut the edge of only the outer races of the bearings; the second aperture having threadably engaged therewith an end screw plug, the screw plug having a cylindrical aperture therethrough coaxial with the second aperture and of larger diameter than the inner diameter of the bearings, the face of the screw plug having a cylindrical protrusion thereon to abut the edge of only the outer race of the second bearing; the spacers, bearings and end screw being of predetermined width such that the end screw holds the bearings and the spacers against the wall of the first end of the cavity to thereby prevent axial movement of the bearings within the assembly. Novel shaft, drive cog and dust cover are also provided for the assembly.
    • 本发明提供了一种新的和有用的轴承组件和利用该组件的主轴。 所述组件包括适于固定在支撑构件中的壳体,所述壳体同轴地布置在其中的圆柱形空腔中,所述空腔与所述壳体的第一端的外部之间的第一圆柱形孔和至少部分螺纹的第二圆柱形 所述腔和所述壳体的第二端之间的孔,所述第二孔的直径等于或大于所述腔; 所述空腔与所述空腔同轴地布置成邻接关系,并且外径足够小于所述空腔的直径,以允许其中的滑动运动,并且从所述第一端开始,间隔件,第一密封径向轴承,第二间隔件, 和第二密封的径向轴承,每个所述间隔件具有大致圆柱形的构造并具有内径,使得所述间隔件仅抵靠所述轴承的外圈的边缘; 所述第二孔与其螺纹接合,所述螺塞具有与所述第二孔同轴并且比所述轴承的内径更大的直径的圆柱形孔,所述螺塞的表面具有在其上邻接的圆柱形突起 只有第二个轴承的外圈的边缘; 间隔件,轴承和端螺钉具有预定的宽度,使得端螺钉将轴承和隔离件抵靠在空腔的第一端的壁上,从而防止轴承在组件内的轴向移动。 还提供了新的轴,驱动齿轮和防尘盖。
