Abstract
The invention provides a crank shaft installation alignment method for a diesel engine of a ten-thousand-ton oil tanker and relates to the field of mechanical assembly. The method includes the following steps that a crank shaft is installed and dragged through left sleeves and right sleeves of center frames, the distance between the end face of the crank shaft and a disc chuck is measured, elastic jaws can correctly clamp the circumference of a flange, before the crank shaft is finally installed in place, the position of each center frame can be properly adjusted, the center frames are prevented from intervening in a crank throw, a dial indicator is installed on the disc chuck, a measuring head is arranged on the circumference of the flange, the disc chuck is rotated, an indicated number of the dial indicator is observed, the left sleeve and the right sleeve of the center frame tightly adjacent to the disc chuck are flexibly adjusted, a dial indicator is arranged on the plane of a front circle of a tail base, the measuring head is arranged on the portion, close to the tail base, of the circumference of the flange, a spindle of the tail base is rotated, an indicated number of the dial indicator is observed, and the left sleeve and the right sleeve of the center frame tightly adjacent to the tail base are flexibly adjusted until the left sleeve and the right sleeve are coaxial in the tolerance. According to the method, time and labor are saved for alignment and overall deformation of the installed crank shaft is small.
Description
Technical field
The present invention relates to mechanical assembling field, be specifically related to million tons wheel crankshaft of diesel engine aligning method is installed.
Technical background
Crankshaft of diesel engine is the main critical movements part of diesel engine.Bent axle is subject to crooked simultaneously and reverses two moments, is one of parts of diesel engine stressing conditions complexity, stressed maximum.In Design Technology for Diesels, bent axle is subject to base bearing radial constraint and thrust plate axial constraint, and reality was restrained condition.For guaranteeing that bent axle respectively turns, stressedly evenly must strictly limit processing and assembly precision and the axiality of each main bearing hole axle, avoid retraining the stressed bearing shell Fast Wearing that causes.Process guarantees main bearing hole axle coaxial accuracy, be generally easy to do, but the bent axle of oil machine and support size is large, Heavy Weight, easily deform, and centering becomes a difficult problem.
Summary of the invention
In order to address the above problem, the invention provides a kind of centering time saving and energy saving, after installing, whole crank shaft is out of shape little million tons wheel crankshaft of diesel engine installation aligning method.
Million tons wheel crankshaft of diesel engine of the present invention is installed aligning method, comprise the following steps: the first step, lay bent axle, with each centre frame left and right sleeve, bent axle is held, and measure crankshaft end-face apart from the distance of floral disc, elastic card claw can be correctly clamped on the circumference of flange, final in place before, can suitably adjust each centre frame position, avoid interfering with crank throw;
Second step, is sitting in dial gauge on floral disc, and gauge head is beaten on circumference of flange, then rotates floral disc, examines dial gauge registration, and motor-driven adjustment is near the left and right sleeve of centre frame of floral disc;
The 3rd step, by gauge stand, before tailstock on disk, gauge head is beaten by the circumference of flange at tailstock place, and rotating tailstock main shaft, observes and represents number, and motor-driven adjustment is simultaneously near the left and right sleeve of centre frame of tailstock, until coaxially in franchise;
The 4th step, with electric drill driver card pawl reinforcement leading screw, makes claw convergence crankshaft flange cylindrical, during approximately apart from the surplus 20mm of cylindrical, with ratchet spanner, and finally with torque spanner locking, then adjusts force value.
Million tons wheel crankshaft of diesel engine of the present invention is installed aligning method, and centering is time saving and energy saving, and after installing, whole crank shaft distortion is little.

Second step, is sitting in dial gauge on floral disc, and gauge head is beaten on circumference of flange, then rotates floral disc, examines dial gauge registration, and motor-driven adjustment is near the left and right sleeve of centre frame of floral disc;
The 3rd step, by gauge stand, before tailstock on disk, gauge head is beaten by the circumference of flange at tailstock place, and rotating tailstock main shaft, observes and represents number, and motor-driven adjustment is simultaneously near the left and right sleeve of centre frame of tailstock, until coaxially in franchise;
The 4th step, with electric drill driver card pawl reinforcement leading screw, make claw convergence crankshaft flange cylindrical, during approximately apart from the surplus 20mm of cylindrical, with ratchet spanner, and finally with torque spanner, lock, then by experience, adjustment is except near main spindle box with near tailstock, the force value of float supports in the middle of all the other centre frames, and empirical value is: No. 2 frame 2.25 MPa; No. 3 frame 3.9 MPa; No. 4 frame 4.25 MPa; No. 5 frame 4.45 MPa; No. 6 frame 4～5 MPa; No. 7 frame 4 MPa, million tons wheel crankshaft of diesel engine of the present invention is installed aligning method, and centering is time saving and energy saving, and after installing, whole crank shaft distortion is little.
Claims (2)
1. million tons wheel crankshaft of diesel engine is installed aligning method, it is characterized in that, comprises the following steps:
The first step, lays bent axle, with each centre frame left and right sleeve, bent axle is held, and measure crankshaft end-face apart from the distance of floral disc, elastic card claw can be correctly clamped on the circumference of flange, final in place before, can suitably adjust each centre frame position, avoid interfering with crank throw;
Second step, is sitting in dial gauge on floral disc, and gauge head is beaten on circumference of flange, then rotates floral disc, examines dial gauge registration, and motor-driven adjustment is near the left and right sleeve of centre frame of floral disc;
