Embodiment Construction

[0032] The present invention will be described in further detail below with reference to the accompanying drawings.

[0033] like figure 2 , image 3 As shown, a method for replacing a journal main body sleeve provided by the present invention includes the following steps:

[0034] Step 1, remove the stop pin through the pin puller;

[0035] Step 2, remove the sleeve on the main body of the journal;

[0036] Step 3, measure the position of the blind hole for the pin connection on the main body of the journal;

[0037] Step 4: According to the measured position, a positioning hole is processed on the new sleeve to be replaced, with a diameter of d2; the purpose of processing the positioning hole is to ensure that there is no interference when the lever dial indicator is used for alignment.

[0038] Step 5, install the new sleeve to be replaced on the journal main body, and the position of the positioning hole is within the diameter range of the pin coupling blind hole on t...

Abstract

The invention provides a method for replacing a shaft neck body sleeve. The method comprises the following steps that 1, a stop pin and the sleeve on a shaft neck body are detached; 2, the position of a pin connecting blind hole in the journal body is confirmed, a positioning hole is machined in a new sleeve to be replaced according to the position, and the hole diameter of the positioning hole is smaller than that of the pin connecting blind hole in the journal body; 3, a new sleeve to be replaced is installed on the journal body, and the position of a pin connecting blind hole in the journal body is aligned; 4, a stop pin hole in a new sleeve to be replaced continues to be machined on the basis of the positioning hole, and the hole diameter of the machined stop pin hole is equal to the hole diameter of an existing pin connecting blind hole in the journal body; step 5, mounting a stop pin; the replacement work efficiency is improved, and the service life of the journal body is prolonged.

Description

technical field [0001] The invention belongs to the field of machining, and in particular relates to a replacement method for a journal main body sleeve. Background technique [0002] For the journal structure of a certain fulcrum bearing installation part, due to technological limitations, two parts of the journal body and the sleeve must be processed separately. After the processing is completed, concentric assembly is performed and a stop pin is used for interference connection. After the service life of the sleeve reaches the limit, the Replacement, the replacement method is to use a drill to drill and remove the stopper pin and then pull out the sleeve, reinstall the new sleeve and process the pin hole to be concentric with the hole on the main body of the journal and the sleeve, and use the stopper pin according to the hole diameter for interference connection. In this method, when drilling and removing the stopper pin and reprocessing the stopper pin hole, the origina...
