Abstract

The invention discloses a method for measuring the double slope of the rear bearing of the stern tube. The method is simple in operation and convenient for construction, solves the problem of how to detect the double slope of the rear bearing of the stern tube in existing ships, and can meet the shipbuilding accuracy. In some cases, it can be extended and used to measure the inclination of the inner bore of the stern tube aft bearing after assembly of other stern tube aft bearings.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for measuring the double slope of a rear bearing of a stern tube. Background technique [0002] The stern tube bearing includes the stern tube front bearing and the stern tube rear bearing. The interior of the stern tube rear bearing is usually designed with a slope to reduce the stress generated by the stern shaft during operation. On some ships, the stern tube rear bearing needs to be designed in two In order to meet the requirements of the classification society. However, according to the latest classification society requirements, after the stern tube rear bearing is assembled, the double slope of the rear bearing needs to be inspected to ensure the assembly quality. How to detect the double slope of the rear bearing of the stern tube has become an urgent problem to be solved. Contents of the invention [0003] In view of this, the present invention provides...
