Description
Technical field
It is pumped more particularly to a kind of gear oil the invention belongs to laser gain material manufacture and electric arc increases material manufacturing technology field
The compound heterogeneous increasing material manufacturing system and method for optical-electronic arc.
Background technique
Gear oil pump is worked using a pair of of gear engagement rotation, mainly by gear, axis, the pump housing, pump cover, bearing holder (housing, cover),
The composition such as shaft end seal, is widely used in the industries such as petroleum, chemical industry, ship, electric power, metallurgy and national defence scientific research.
Gear oil pump is that the key device of reliable power is provided in hydraulic system, requires gear oil pump to have in mechanical system
The characteristics such as stable working reliable, long service life, resistance to shock loads；But the gear oil pump pump housing often occurs in actual operation
Wear phenomenon seriously affects the working life and reliability of gear oil pump；The gear oil pump pump housing is primarily present two kinds of abrasive manners:
First is that effect of the working gear by pressure oil, gear teeth tips cause the low pressure cavity segment on the inside of the pump housing serious close to oil pump case
Abrasion；Second is that oil liquid is not clean, pump housing inner working face is caused circumferentially to wear.
In conventional gears oil pump, the usual via nitride processing of gear has higher hardness and wearability, and works in the pump housing
The wearability in face is then poor, will cause the abrasion of pump housing inner working face, and the fit clearance between the pump housing and gear is made to become larger, and causes interior
Leakage, so that the volumetric efficiency of gear pump declines, oil pump output power is lower than input power significantly, and loss is completely reformed into
Thermal energy causes oil pump to overheat, and also influences the pumping ability and precision of oil pump.

And the reparation of part.
Mainstream metal increasing material manufacturing method more mature at present is laser gain material manufacture and electric arc increasing material manufacturing；Laser gain material
Manufacturing technology, which mainly passes through, melts it successively using laser irradiation metal powder or metal welding wire, and molten material is according to phase
The workpiece profile answered gradually adds up, to manufacture the technology of entity component；Electric arc increases material manufacturing technology refers to using electric arc as heat
Metal welding wire is melted in source, and synusia is then accumulated on substrate by setting forming path, and heap applies until metal parts shapes layer by layer
Terminate；Electric arc increasing material manufacturing formation of parts is made of full weld metal, and compactness is high, metallurgical bonding performance is good, chemical component is equal
It is even, mechanical property is good, compared to laser gain material manufacturing technology, electric arc increases material manufacturing technology has that at low cost, shaping rate is fast, energy
The advantages that enough shaping coarse scale structures part, but its forming accuracy is relatively poor；Laser gain material manufacturing technology has forming accuracy
It is higher, the advantages that complex-shaped part can be manufactured, but its forming efficiency is low compared with the former, equipment cost is high；From forming efficiency,
The various aspects such as forming quality, organization mechanics characteristic, the adaptability of complex parts consider that two kinds of increasing material technologies all have each opposite sex,
It individually cannot all reach the manufacture requirement of the heterogeneous pump housing blank of gear oil pump using any increasing material manufacturing mode.
Therefore, it is necessary to invent a kind of high efficiency, high quality, low cost, adaptable increasing material manufacturing system and method, and
It can be realized the ability of subregion increasing material manufacturing, the simple substance increasing material manufacturing or heterogeneous increasing material manufacturing of component of machine, to realize
The quick production of the heterogeneous pump housing blank of gear oil pump.
