Abstract
The invention provides a ship stern bearing inner hole bevel detecting method. A light target support is arranged at one end of the section between a head support opening and a tail support opening inside a stern bearing, a light tube is installed at the other end of the section through a light tube mandrel, a measuring rod is installed on one side of the light tube, a dial indicator is arranged between the light tube and the measuring rod, a collision telescope is arranged outside the stern bearing, and the ship stern bearing inner hole bevel value is measured through the measuring rod and the dial indicator. The method has the advantages that the defect of the prior art that a professional electronic instrument is needed to measure the deviation of the center line of an inner hole of the stern bearing, and therefore cost is high is overcome, tool manufacturing is easy, cost is low, tools can be repeatedly used, operation is convenient, and measurement precision is guaranteed. The method is suitable for installation and measurement of various bearings.
Description
Technical field
The inventive method relates to greatly, the ship stern brearing bore knuckle detection method of the separate-blas estimation of the stern bearing inner hole centreline of medium and small-scale vessel stern tube shaft.
Background technology
In large, medium and small shipbuilding process, the stern bearing inner hole centreline of most stern tube shaft has deflection angle in a pre-installation, and stern bearing inner hole centreline Deviation Design is according to requirement in centering of shafting calculated description, to meet marine shafting load.At building berth installation phase, it is all the most important thing that stern tube shaft stern bearing is installed, and most shipyard is all adopt interference fit between bearing and axis hole, by pressing sleeve tool, ensures that bearing is correctly press-fit into place.After stern bearing is press-fit into place, needs to detect stern bearing endoporus centerline deviation after mounting and whether meet technological requirement.As measured value difference is comparatively large, carries out corresponding preventive measure early, avoid occurring great quality accident.Measure the electronic device that stern bearing centerline deviation needs specialty, be installed in brearing bore, drawn the centerline deviation of brearing bore by electronic device information feed back.
Summary of the invention
In order to realize the monitoring of ship stern bearing installment state, the present invention proposes ship stern brearing bore knuckle detection method.The method utilizes the principle of sight alignment, realizes the measurement to ship stern bearing inner hole centreline deviation by professional tool and frock.Solve the technical matters that ship stern bearing installment state detects.
The scheme that technical solution problem of the present invention adopts is:
In stern bearing, stem props up mouth and afterbody props up between mouth, and one end arranges light target support, and the other end is equipped with light pipe by light pipe mandrel, at light pipe side installing sounding rod, is equipped with dial gauge, installs put collimating telescope in stern bearing outside between light pipe and sounding rod.Boats and ships stern bearing endoporus knuckle value is measured with sounding rod and dial gauge.
The inventive method advantage: measure the electronic device that stern bearing inner hole centreline deviation needs specialty, cost compare is high, and this inventive method frock making is simple, and cost is low, and frock is reusable, easy to operate, and measuring accuracy also can be guaranteed.Suitable to multiple bearing installation and measuring method application.

Embodiment
In stern bearing 7, stem props up mouth and afterbody props up between mouth, one end arranges light target support 3, and the other end is equipped with light pipe 1 by light pipe mandrel 2, at light pipe side installing sounding rod 5, between light pipe and sounding rod, be equipped with dial gauge 4, install in stern bearing outside and put collimating telescope 6.
(1) make the frock measuring stern bearing endoporus deviation, prepare related tool:
(2) first light pipe holder and light pipe are arranged on stern bearing endoporus place, find suitable position, between the supporting leg of light pipe holder and brearing bore, adopt copper sheet to separate, play the effect of protection brearing bore, fix light pipe by light pipe holder simultaneously.
(3) thick centering: mandrel is penetrated in light pipe, sounding rod loads core axle hole after being connected with dial gauge interior and fix, and the head and the tail that dial gauge indicator adjusts to bearing prop up on mouthful internal diameter, wheel measuring bar, and whether observation dial gauge range meets.Summit is propped up on mouth for starting point with stern bearing initial and end, dial gauge returns to zero, turn clockwise sounding rod observed reading, as upper and lower, left and right measured value is inconsistent, regulated the position at light pipe center by light pipe holder, make a stern bearing head and the tail mouth internal diameter upper and lower, left and right four direction apart from roughly equal.
(4) smart centering: install collimating telescope, is encased in light pipe A point, D point place target center, with the A of stern bearing stern point and stern bearing bow D point for reference point, with collimating telescope check and correction A point and D point position, and makes it point-blank by adjustment light pipe holder.
Above regulate complete after, the first step is first being put into B point place the target core of stern A point, regulates B point by collimating telescope and A point, D point, and make collimating telescope and A point, B point, D point point-blank, target core is taken away; Second step is transposed to C point target core, regulates C point, make collimating telescope, C point, D point point-blank by collimating telescope and D point; After above step terminates, reply A point and D point, situation of change after observation A point, D point relative collimation telescope adjustment are complete, owing to regulating B point, C point causes A point, D point reference point changes, cause A point, D point may not be point-blank, continue adjustment A point, D point more point-blank, repeat above two steps: until satisfied 4 points all with collimating telescope point-blank, just can continue to carry out downwards.
(6), after above centering terminates, light pipe mandrel is penetrated in light pipe, by light pipe mandrel lean out light pipe distance length, choose at brearing bore place measurement point X 1., X 2., X 3., X 4., X 5., X 6., X 7., X 8., X 9., X 10.; Measurement point distance can adjust according to actual conditions, and in the middle of general, measurement point distance is approximately 100mm, and two-sided measurement point is about 40mm, 80mm.Just upper right for zero point with stern bearing endoporus, by sounding rod clockwise or be rotated counterclockwise dial gauge, record the dial gauge reading of 0 °, 45 °, 180 °, 315 ° respectively, represented by stern bearing inner hole centreline measured deviation record sheet, then mandrel is measured next measurement point and record in shift position.Stern bearing inner hole centreline bias measures after contrast installation and the measured value before press-fiting, bias measures unanimously could meet technological requirement.
The inventive method easy construction, save workmen, frock making cost is low, and construction method is simply easy to workmen and understands and operation, and saving the engineering time improves work efficiency, and measuring accuracy also can be guaranteed.
