Problems solved by technology

[0005] In view of the problem that the eccentric distance between the center of the propeller and the center of the detection platform cannot be eliminated in the process of propeller static balance detection, the present invention proposes an error compensation method for propeller static balance detection. The eccentricity between the centers is compensated to eliminate the influence of the eccentricity on the unbalanced quality of the final detection result, which can greatly improve the accuracy of propeller static balance detection, so that the final error is in a very small range

Embodiment Construction

[0036] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] The present invention proposes an error compensation method for static balance detection of a large marine propeller, and the specific steps are as follows:

[0038] Analyzing sources of error

[0039]The main factors affecting the error of propeller static balance detection are the distance between the center of the propeller and the center of the detection platform during the process of propeller alignment and the error of the sensor used on the detection platform, but only the center of the propeller and the center of the detection platform during the process of propeller alignment The offset distance can be compensated but the detection error of the sensor cannot be avoided. Such as figure 1 As shown, we compensate the errors generated in the detection process by measuring the eccentric distance between the center of ...

Abstract

The invention discloses a device for propeller static balance detection and an error compensation method thereof. The influence of an eccentric distance on the unbalanced quality of a final detectionresult is eliminated by compensating the eccentric distance between the center of a propeller and the center of a detection platform in a later period, the precision of the propeller static balance detection can be greatly improved, and a final error is in a very small range.

Description

technical field [0001] The invention relates to the technical field of static balance detection, in particular to an error compensation method used in the static balance detection of marine propellers. Background technique [0002] Propellers are the core power components of ships. With the continuous development of the times, our requirements for ships are getting higher and higher. High speed and high precision have become synonymous with modern ships. The continuous pursuit of high-speed and high-precision propellers also means that the requirements for the elimination of propeller static unbalance quality are also constantly increasing, which requires us to further improve the propeller static balance detection method. [0003] At present, the existing propeller static balance detection is mainly realized by two methods: the balance shaft rolling method and the swing method vertical balancer detection method, and the existing static balance detection equipment is mainly ...
