Abstract
The invention discloses a method for rapidly repairing gears, and relates to transmission gears. The method solves the problem that how a gear can be rapidly put back on production after a tooth of the gear is broken. The method comprises the following steps: finding out a center line of a damaged tooth of a gear, machining a dovetail groove at the root part of the damaged tooth of the gear, making a new tooth, machining grooves on two sides of the root of the new tooth, drilling a through hole perpendicular to the top of the new tooth on the new tooth, machining a threaded hole at the root part of the damaged tooth of the gear, fixing the new tooth to a damaged tooth through a countersunk bolt, welding and performing thermal insulation and cooling at the grooves on the two sides of the new tooth, welding and grinding the head part of the countersunk bolt, and performing tooth shape polishing and inspection. The method is used for repairing gears, and has the advantages of simplicity, convenience for operation, high speed and practicality.
Description
Technical field
The present invention relates to mechanical drive gear.Be particularly related to a kind of method of quick reparation gear tooth.
Background technology
Plant equipment field, gear drive are very general.In the place that load is large, operating rate is high, environment for use is more abominable, the exposed gear that particularly modulus is large, external diameter is large, the easier tooth of beating often can appear in gear is beaten tooth (tooth or several tooth damage) in running phenomenon.Generally, gear teeth local damage can be adopted reconditioning after the repair welding, continues to use; If whole tooth damages, just need more renew gear.After gear is beaten tooth, if there is not spare part (new gear) in time more to renew gear, will affect the normal operation of equipment, can cause serious economic loss to enterprise.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, a kind of method of quick reparation gear is provided, after the solution gear is beaten tooth, do not having in the situation of spare part, the normal technical problem of producing of the equipment that will affect.
The present invention is achieved by the following technical solutions:
A kind of method of quick reparation gear is characterized in that: the concrete steps of described method:
1, according to gear centre O, and decreased gear teeth center line OB and the OC of gear teeth both sides, found out the former center line OA that is decreased the gear teeth;
2, according to the size of module, decreased dovetail groove 3 of root processing of the gear teeth;
3, new tooth 1 that decreases gear teeth identical appearance size, cooperates with described dovetail groove with quilt of processing and fabricating;
4, in the tooth root both sides of new tooth 1, process 45 ° of grooves of weld seam;
5, bore the through hole 1-1 of 2～3 vertical tooth tops at new tooth, and by damage gear teeth root, along on the position of its center line OA, process the screwed hole that cooperates with dormant bolt 2;
6, new tooth 1 usefulness dormant bolt 2 is fixed in damage tooth place;
7, formulate welding procedure according to the material of gear, in the welding of the groove place of new tooth both sides, insulation cooling;
8, the head of dormant bolt 2 is welded polishes again;
9, carry out at last profile of tooth reconditioning, check.
The present invention compared with prior art, because beating suddenly tooth in the gear running damages, there is no that new gear changes situation under, can in time make a new tooth, fix, weld at damage tooth position, take " kind tooth " method to repair gear, normal production that can very fast restorer has reduced left alone without help product loss.The present invention is used for the reparation of gear, and it is simple to have method, easy to operate, the advantage of Fast Practical.
Description of drawings
Fig. 1 is the structural representation that adopts gear teeth of the present invention's reparation;
Fig. 2 is the top view of tooth top.
The present invention is further illustrated by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, 2, a kind of method of quick reparation gear is characterized in that: the concrete steps of described method are:
1, according to gear centre O, and decreased gear teeth center line OB and the OC of gear teeth both sides, found out the former center line OA that is decreased the gear teeth;
2, according to the size of module, decreased dovetail groove 3 of root processing of the gear teeth;
3, new tooth 1 that decreases gear teeth identical appearance size, cooperates with described dovetail groove with quilt of processing and fabricating;
4, in the tooth root both sides of new tooth 1, process 45 ° of grooves of weld seam;
5, bore the through hole 1-1 of 2～3 vertical tooth tops at new tooth, and by damage gear teeth root, along on the position of its center line OA, process the screwed hole that cooperates with dormant bolt 2;
6, new tooth 1 usefulness dormant bolt 2 is fixed in damage tooth place;
7, formulate welding procedure according to the material of gear, in the welding of the groove place of new tooth both sides, insulation cooling;
8, the head of dormant bolt 2 is welded polishes again;
9, carry out at last profile of tooth reconditioning, check.
The present invention can resume production as early as possible, has reduced left alone without help product loss, prepares spare part for enterprise simultaneously and is full of the time of having made.
