Description
Technical field
The present invention relates to gear maintenance crafts, and in particular to a kind of renovation technique of questions of drive gear tooth.
Background technique
ZG150--1500 type electric locomotive is the larger transport devices in railway transportation, the especially fortune in industrial and mining enterprises
It is defeated, be all using continuous current locomotive as major impetus, transmission gear is the important component of electric locomotive, without its locomotive without
Method operation, so transmission gear daily maintenance and maintenance and its important are carried out, in the daily maintenance of gear, often because one or partly
A gear teeth damage and replace a new transmission gear, and the replacement cost of each gear is more than 7,000 yuan, when replacement quantity is more, take
With larger；And the gear damaged is discarded substantially and is not recycled, and the waste of resource is also resulted in；It needs to use when more gear changing simultaneously
The press machine of 500t is split, and the process of fractionation needs craneman to cooperate completion, and new gear needs the processing by turner
It can be only achieved tolerance fit requirement, assembly technology is also required to press machine and is pressed a step by a step go back, and process is tedious for whole process, work
It measures also bigger.
Summary of the invention
Technical assignment of the invention is to be directed to the above the deficiencies in the prior art, and provide a kind of reparation of questions of drive gear tooth
Technique.
The technical solution adopted by the present invention to solve the technical problems is: the renovation technique of questions of drive gear tooth, including such as
Lower step:
(1) greasy dirt and other impurity of gear defect are removed；
(2) welding rod is put into drying box, heat dries 50~70min after being warming up to 300~350 DEG C, is then cooled to automatically
130~170 DEG C；
(3) repair welding position is preheated using gas welding, preheating temperature is 150~200 DEG C；
(4) layering built-up welding is taken, weldering meat height is higher than 2~5mm of the prototype gear teeth, while the weldering meat of gear teeth two sides is also than original
The every side of the type gear teeth has more 2~5mm；
Further, the concrete operations in the step 1 are as follows: the greasy dirt that gear defect is cleaned with diesel oil, using height
Pressure air blows away the impurity in gear clearance.
Further, it in the step 4, is layered in weld deposit process, the welding direction of per pass weld seam is opposite.
Further, the welding rod is 506# welding rod or 507# welding rod.
Further, after step (4) further include: gear repair welding is completed, and after natural cooling, carries out tooth to backgear is repaired
Mould detection, and redundance is removed using angle grinder, until reaching former gear teeth standard.
Further, after step (4) further include: to engagement test is carried out after the gear assembling after reparation, detect its biography
Dynamic state.
Further, the renovation technique is suitable for the gear tooth that defect degree is lower than 2/3.
The renovation technique of questions of drive gear tooth provided by the present invention, suitable for the reparation of relatively large gear, technique step
Suddenly be simple and convenient to operate, rehabilitation cost it is low, effectively save labour, improve working efficiency, can resume production as early as possible, have
There is biggish economic benefit.
