Embodiment Construction

[0026] exist figure 1 In the simplified diagram of , there is a test unit 2 for the quantitative analysis of the contact pattern on the tooth flank 4 of the gear 6 . Just for the simplification of the drawing, the figure 1 Only a section of gear 6 is depicted in . In particular, the gear 6 forms part of a wind generator.

[0027] The testing unit 2 comprises an optoelectronic sensor 8 for capturing images of the contact pattern paint applied on the tooth flank 4 . In particular, the optoelectronic sensor 8 is a camera, for example a digital camera, configured to capture digital images of the tooth flank 4 . The optoelectronic sensor 8 can be a color sensor or a gray scale sensor. For example, a digital color camera or a black-and-white camera, respectively configured to capture a digital color image or a digital grayscale image of the tooth surface 4 , may be used.

[0028]The optoelectronic sensor 8 is coupled to the control unit 10 via a data link 12 . Both the control...

Abstract

A test unit for quantitative analysis of a contact pattern and a method for quantitative analysis are provided. The test unit comprises an optoelectronic sensor for capturing images of contact pattern paint on a tooth surface of a gear. Furthermore, the test unit comprises a control unit, which is configured for determining and storing a first distribution of an optical parameter of the contact pattern paint across the tooth surface, from the first image. This is captured prior to testing of the gear. After the tooth surface was exposed to a test load, a second image is captured and a second distribution of the optical parameter is determined. The control unit is configured to perform a quantitative analysis of a contact pattern on the tooth surface by determining a deviation between the first and the second distribution of the optical parameter.

Description

technical field [0001] The invention relates to a test unit for the quantitative analysis of contact patterns on tooth surfaces of gears, in particular gears in wind power generators. The invention also relates to a method for the quantitative analysis of contact patterns on tooth surfaces of gears. Furthermore, the invention relates to the use of a test unit for the quantitative analysis of contact patterns on tooth surfaces of gears of wind power generators. Background technique [0002] Generally, the tooth flanks in gears do not contact each other over the entire tooth flank. To determine the contact area between the cooperating tooth flanks, a contact pattern paint, which is an oil-resistant colored paint, was applied to the tooth flanks prior to testing. The gears are then exposed to test loads. The contact pattern paint wears away due to the applied force on the tooth flanks bearing part of the paint and the resulting contact pattern, which is then visually inspect...
