Embodiment Construction

[0058] figure 1 A device 1 in the form of a planetary gear 1 a with relatively movable elements 2 , 3 , 4 and 5 is shown in side view and not to scale. Element 2 is the sun gear 2a and element 3 (first element 3 ) is a planetary gear 3a which is in toothed engagement with the sun gear 2a. The element 5 is the ring gear 5a with which the planet gears 3a are in tooth engagement. The element 4 (third element 4) is the planet carrier 4a.

[0059] figure 2 along the basis figure 1 The line II-II shows a cross-sectional view of the details of the device. For each planet gear 3a, a further element 6 (second element 6), which is formed as a planet pin 6a, is fastened to the planet carrier 4a. Each planet gear 3 a is mounted rotatably about an axis of rotation 7 a on a planet pin 6 a (on the second element 6 ) by means of a rolling bearing 7 . Each planetary gear 3a is in toothed engagement with the ring gear 5a and with the sun gear 2a. The axis of rotation 7 a is spaced at ...

Abstract

The invention relates to a device (1) with elements (2, 3, 4, 5, 6, 8, 16) which can be moved relative to one another and at least one first element (3) of which is mounted on a second element (6) in a rotatable or pivotal manner at at least one bearing point. The second element (6) is mounted on a third element (4), which can be rotated about a central axis (17) of the device (1), at a radial distance from the central axis (17) of the device (1). The bearing point has at least one fourth element (8) which is in sliding contact with one of the elements at least temporarily in at least one sliding contact zone. At least one section of the surface of at least one of the elements of the device has at least one layer made of a nickel-phosphate alloy in the sliding contact zone, wherein particles (17) of at least one solid-state lubricant are distributed in the layer.

Description

technical field [0001] The invention relates to a device with relatively movable elements, preferably a planetary gear, in which at least one first element is rotatably or pivotally mounted on a second element at at least one bearing point, wherein the first The two elements are mounted at a radial distance from the center axis of the device on a third element rotatable about the center axis of the device, and wherein the bearing point has at least one fourth element in at least one sliding contact region At least temporarily in sliding contact with one of these elements. Background technique [0002] Such a device is an eccentric gear, such as a planetary gear. [0003] In the case of a planetary gear, in the respective bearing point, each planet gear is rotatably mounted on a planet pin by means of at least one roller bearing. The planetary pins are fixed on the planetary carrier at a certain radial distance from the central axis of the planetary gear transmission. If t...
