    • A compound sprocket having at least one rotatable member including an outer sprocket element and an inner sprocket element symmetrically disposed relative to a central axis of rotation of the at least one rotatable member. The outer sprocket element includes a plurality of spaced, uniformly radially-oriented protrusions on an outer cylindrical surface thereof for engaging a conveyor belt, the outer sprocket element further includes a plurality of pockets formed on an inner cylindrical surface thereof. The inner sprocket element has a plurality of protrusions corresponding in number and position to the pockets formed on the inner cylindrical surface of the outer sprocket element and received therein. A resilient connecting element is disposed in each pocket biased between a wall of the pocket of the outer sprocket element and one of the protrusions of the inner sprocket element.

    • The invention relates to a chain wheel arrangement for chain drives of mining machines, with a chain wheel shaft 1, with a chain wheel, with bearing shells 4 receiving bearings 5 for the chain wheel shaft, with a chain wheel-side sliding ring seal 42 and with a bearing-side sliding ring seal 41. In order to improve the service life of the chain wheel arrangement, at least one of the bearings 5, preferably that of the movable bearing system 3, is arranged in a bearing bush 50 which is arranged between the bearing shell 4 and outer bearing ring 5B and received in the bearing shell 4 in an axially displaceable manner. The additional bearing bush 50 allows the necessary gap between the rotating parts and the non-co-rotating, bearing shell-side parts to remain substantially constant and to this extent to become independent of the bearing play of the respective bearings.
    • 本发明涉及一种用于采矿机链式传动的链轮装置,其具有链轮轴1,其具有链轮,其中轴承壳体4接收链轮轴的轴承5,链轮侧滑环密封件42 并且具有轴承侧滑环密封件41.为了提高链轮装置的使用寿命,至少一个轴承5(优选可移动轴承系统3)的轴承5布置在轴承衬套50中,轴承衬套 布置在轴承壳体4和外轴承环5B之间,并以可轴向移动的方式容纳在轴承壳体4中。 附加轴承衬套50允许旋转部件和非共同旋转的轴承外壳侧部件之间的必要间隙保持基本上恒定,并且在这种程度上变得独立于各个轴承的轴承间隙。
