Rotary connection for a work machine

摘要

A rotary connection for a work machine, such as a crane, includes a rotational axis, an inner bearing ring, an outer bearing ring and at least three bearing body ring arrangements arranged between the bearing rings with a plurality of respective bearing bodies. At least one of the bearing body ring arrangements is configured to at least partially withstand forces directed in the radial direction to the rotational axis. At least two of the bearing body ring arrangements are configured to at least partially withstand forces directed parallel to the rotational axis and are arranged adjacent to and spaced apart from one another along the rotational axis. The at least two bearing body ring arrangements are configured to at least partially withstand forces directed parallel to the rotational axis in each case establish a direction of action and are arranged spaced apart from one another along the direction of action.

主权项

1. A rotary connection for a work machine, with
a. a rotational axis, b. an inner bearing ring, c. an outer bearing ring, and d. at least three bearing body ring arrangements arranged between the inner bearing ring and the outer bearing ring, each bearing body ring arrangement comprising a plurality of respective bearing bodies, wherein at least one of the bearing body ring arrangements is configured to withstand forces directed in the radial direction to the rotational axis, wherein at least two of the bearing body ring arrangements are configured to withstand forces directed parallel to the rotational axis, wherein said at least two bearing body ring arrangements are arranged adjacent to one another along the rotational axis such that no further bearing body ring arrangement is provided between said at least two bearing body ring arrangements, and wherein said at least two bearing body ring arrangements are arranged spaced apart from one another along the rotational axis such that said at least two bearing body ring arrangements are in a stepped arrangement, and wherein the at least two bearing body ring arrangements configured to at least partially withstand forces directed parallel to the rotational axis in each case establish a direction of action and are arranged spaced apart from one another along the direction of action.
