Embodiment Construction

[0035] Although the invention has been illustrated and described in detail by means of preferred embodiments, the invention is not limited to the disclosed examples. A person skilled in the art can derive variants from this example without departing from the scope of protection of the present invention, as it is defined by the following claims.

[0036] figure 1 A sectional view of a two-stage planetary gear 1 for use in a wind power plant is shown, which comprises a first planetary gear stage 11 on the drive side and a second planetary gear stage 12 on the output side. The output shaft of the transmission mechanism 11 is coupled with the generator. The sun shaft 6 of the first planetary gear stage 11 is coupled in a rotationally fixed manner to the planetary carrier 8 of the second planetary gear stage 12 .

[0037] There are several rotating coordinate systems in planetary gear 1:

[0038] a) The transmission mechanism housing 9 and the ring gear 15 form a first coordinat...

Abstract

The invention relates to a measuring system for detecting variables on planetary carriers of a planetary gearing (1) comprising at least multiple planetary gear stages (11, 12), wherein at least each planetary gear stage (11, 12) comprises a respective sun shaft (6, 162), at least one respective ring gear (15, 19) and at least one respective planetary gear (10, 25) which is connected to the respective sun shaft (6, 162) and the respective ring gear (15, 19) by a toothed engagement, and a respective planetary carrier (5, 8) which is assigned to the at least one planetary gear (10, 25) and is rotationally connected to the at least one planetary gear (10, 25), wherein at least one first sensor, having at least one connection for supplying the at least first sensor with electrical energy, is arranged on at least one of the planetary carriers (5, 8) on at least one of the planetary gear stages (11, 12) for detecting variables of the assigned planetary gears (10, 25), and wherein the planetary gearing (1) has electronics by means of which the at least one first sensor can be supplied with electrical energy and wherein the at least one planetary gear stage (11, 12) is selectable from each of the available planetary gear stages (11, 12).

Description

technical field [0001] The invention relates to a measuring system for detecting variables on a planetary carrier of a planetary gear comprising at least a plurality of planetary gear stages, wherein each planetary gear stage comprises at least one sun shaft, one ring gear each There is also at least one planet gear and a planet carrier associated with the at least one planet gear, the planet gears being connected via toothing to the corresponding sun shaft and the corresponding ring gear, and the planet carrier being rotatably connected to the at least one planet gear. Background technique [0002] Compared with the traditional spur gear transmission and bevel spur gear transmission, the planetary transmission mechanism provides obvious advantages in terms of power density and specific torque, and the planetary transmission mechanism includes a sun shaft, a planet carrier with planetary gears and an internal distribution toothed hollow wheel. Due to the cylindrical basic s...
