Abstract
The utility model discloses an engine crankshaft flange, which belongs to the technical field of engine remanufacturing. The engine crankshaft flange comprises a crankshaft flange body, wherein one end of the crankshaft flange body is connected with a main journal of the engine flange, the other end of the crankshaft flange body is provided with threaded holes and a cylindrical boss, the threaded holes and the cylindrical boss are used for being connected with a flywheel of an engine, the outer surface of the crankshaft flange body is provided with an annular groove formed by removing wear marks, a laser cladding coating is arranged in the annular groove, and the laser cladding coating is flush with the excircle of the crankshaft flange body. The laser cladding coating and the crankshaft flange body are in metallurgical bonding with high bonding force and are prevented from falling off in use; by adopting a laser cladding manner, instant high temperature can be generated, the heat affected zone is small, and the defects of cracks and the like are avoided, so that the repair for the engine crankshaft flange with the groove formed by wearing the excircle is realized, and remanufacturing of the engine crankshaft flange is further realized.
Description
Technical field
The utility model belongs to engine remanufacturing technical field, relates in particular to a kind of engine crankshaft flange.
Background technique
Engine crankshaft is one of important spare part of motor, is also to hold one of flimsy key components and parts, and on market, learies and demand are much larger than motor.Crankshaft flange is positioned at one end of bent axle, is a part for composition bent axle, the main journal of its one end connecting engine bent axle, the other end is threaded hole and cylindrical boss, be used for connecting flywheel outputting power, on its cylindrical, assemble oil sealing, make engine interior form Seal cage.
Bent axle uses after certain hour, position that can contact with oil sealing on crankshaft flange cylindrical forms groove because of wearing and tearing, affect sealing effect, cause engine oil leakage, ubiquity on bent axle under the bent axle that this phenomenon is pulled down at old machine and engine overhaul replacing, the reparation of this defect is that engine crankshaft is manufactured one of the technical barrier that need to break through again.
At present, in prior art, the reproducing method of engine crankshaft flange mainly contains following two kinds:
First method adopts thermal spraying mode will wear and tear the rear reconditioning of groove repairing to maintaining an equal level with flange excircle, but the coating after thermal spraying and bulk junction are combined into mechanical adhesion, restricted by combination force, in use, easily occur that the phenomenon such as coating shedding, alice causes oil sealing to damage, and then cause engine oil leakage;
Second method adopts singly joins oil sealing, high but accessory can not general and singly be made into, and owing to wearing and tearing groove not being repaired, what groove place contacted with oil sealing is bent axle body, and hardness is low, wears no resistance, and quick abrasion, is prone to engine oil leakage phenomenon.
Model utility content
Technical problem to be solved in the utility model is: a kind of engine crankshaft flange is provided, and wearing and tearing to foreign round form the engine crankshaft flange of groove and repair, and realize manufacturing again of engine crankshaft flange.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of engine crankshaft flange, comprise crankshaft flange body, described crankshaft flange body one end connects the main journal of described engine crankshaft, the other end is threaded hole and cylindrical boss, described tapped hole and cylindrical boss are for being connected the flywheel of described motor, the outer surface of described crankshaft flange body is provided with removes the circular groove that wear trace forms, in described circular groove, be provided with laser cladding coating, the cylindrical of described laser cladding coating and described crankshaft flange body maintains an equal level.
Improve as one, described laser cladding coating is alloy-layer.
Adopt after technique scheme, the beneficial effects of the utility model are: because engine crankshaft flange comprises crankshaft flange body, the outer surface of described crankshaft flange body is provided with removes the circular groove that wear trace forms, in described circular groove, be provided with laser cladding coating, the cylindrical of described laser cladding coating and described crankshaft flange body maintains an equal level, thereby adopt the mode of laser melting coating to form laser cladding coating at circular groove place, laser cladding coating and crankshaft flange body be combined into metallurgy combination, combination force is high, in use, there will not be and comes off; And laser melting coating mode produces moment high temperature, and heat affected zone is little, there will not be defects i.e.cracks.The utility model has been realized the engine crankshaft flange of the groove of wearing and tearing formation to foreign round and has been repaired, and then realizes manufacturing again of engine crankshaft flange.
Hardness because described laser cladding coating is alloy-layer, thereby can obtain higher hardness and wear resistance by the composition of adjusting alloy-layer, more than can reach HRC50.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation with the engine crankshaft flange of circular groove;
In figure: 1, crankshaft flange body, 2, main journal, 3, cylindrical boss, 11, circular groove, 12, laser cladding coating.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1 and Fig. 2 are common, a kind of engine crankshaft flange, comprise crankshaft flange body 1, the main journal 2 of crankshaft flange body 1 one end connecting engine bent axle, the other end is threaded hole and cylindrical boss 3, tapped hole and cylindrical boss 3 are for the flywheel of connecting engine, the outer surface of crankshaft flange body 1 is provided with removes the circular groove 11 that wear trace forms, in circular groove 11, be provided with laser cladding coating 12, laser cladding coating 12 maintains an equal level with the cylindrical of crankshaft flange body 1, preferably, laser cladding coating 12 is alloy-layer, alloy-layer can be selected ferrous alloy, nickel-base alloy, cobalt base alloy etc., obtain higher hardness and wear resistance by the composition of adjusting alloy-layer, more than hardness can reach HRC50.
The engine crankshaft flange that the utility model provides, owing to comprising crankshaft flange body 1, the outer surface of crankshaft flange body 1 is provided with removes the circular groove 11 that wear trace forms, in circular groove 11, be provided with laser cladding coating 12, laser cladding coating 12 maintains an equal level with the cylindrical of crankshaft flange body 1, thereby adopt the mode of laser melting coating to form laser cladding coating 12 at circular groove 11 places, the metallurgy combination that is combined into of laser cladding coating 12 and crankshaft flange body 1, combination force is high, in use, there will not be and comes off; And laser melting coating mode produces moment high temperature, and heat affected zone is little, there will not be defects i.e.cracks.The utility model has been realized the engine crankshaft flange of the groove of wearing and tearing formation to foreign round and has been repaired, and then realizes manufacturing again of engine crankshaft flange.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
