An axial mounting of the planetary gearwheels of a planetary gearset having a sun gear that meshes with at least one planetary gearwheel mounted on a planetary bolt that is supported on the planetary carrier. The at least one planetary gearwheel meshes with a ring gear. At least one check-plate, which has a hole for the planetary bolt and which is positioned on one side of the planetary gearwheel between the planetary gearwheel and the planetary carrier, is associated with each planetary gearwheel. The check-plate is completely flat and is axially symmetrical relative to its longitudinal and transverse axes. The at least one check-plate has two wings that extend in the longitudinal direction, which are positioned in recesses formed in the planetary carrier, when the check-plate is in the installed condition, to secure the check-plate against rotation. The check-plate is fixed relative to the planetary carrier. |

1. An axial mounting for planetary gearwheels of a planetary gearset comprising
a sun gear which meshes with at least one planetary gearwheel being mounted on a planetary bolt supported on a planetary carrier (1), the at least one planetary gearwheel meshing with a ring gear, at least one check-plate (2) being associated with each of the at least one planetary gearwheel of the planetary gearset, the at least one check-plate (2) having a circular hole (3) for receiving and engaging with the planetary bolt defining a planet gear rotational axis, and the at least one check-plate (2) being positioned on one side of the at least one planetary gearwheel, between the at least one planetary gearwheel and the planetary carrier (1), the at least one check-plate (2) being completely flat and defining a plane which extends normal to the planet gear rotational axis, being axially symmetrical relative to both longitudinal and transverse axes (4, 5) of the at least one check-plate, and both the longitudinal and the transverse axes (4, 5) lie in the plane defined by the at least one check-plate (2); the check-plate (2) having two opposed wings (6, 7) which extend in the longitudinal direction, along the longitudinal axis (4) of the check-plate (2), so that a longitudinal length of the check-plate (2), along the longitudinal axis (4), being greater than a transverse longitudinal length of the check-plate (2), along the transverse axis (5), and each of the wings (6 or 7) of the check-plate (2) being accommodated within a respective recess (8 or 9) formed in the planetary carrier (1), when the check-plate (2) is in an installed condition, so the wings (6 or 7) secure the check-plate against rotation, and the check-plate (2) being fixed relative to the planetary carrier (1). |
