Description
Technical field
The present invention relates to electric machine stand technical field, particularly a kind of manufacturing process of driving motor for electric automobile benzvalene form support.
Background technology
The perpendicularity of motor stator two ends seam on the axiality of front and rear cover bearing chamber, support and end cap mating surface is the main cause affecting motor oscillating, noise.Conventional electric electric motor of automobile support and end cap adopt split type processing, then assemble, due to positioning datum disunity in the course of processing, support seam and bearing with end cover room axiality poor, cause the circular runout of dynamical system main shaft larger, cause dynamical system noise excessive, produce abnormal sound, even during entrucking, car load drive system is caused and has a strong impact on.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of support and rear end cap to be integrated, improve the manufacturing process of driving motor for electric automobile benzvalene form support of assembly precision.
Object of the present invention is achieved through the following technical solutions: driving motor for electric automobile benzvalene form support, it comprises tubular body and rear end cap integrated with main body, the front end face of main body is circumferentially evenly equipped with connecting screw hole, the front end of body inner surface is provided with front seam, and rear end cap is provided with bearing chamber.
The outer face of described rear end cap is provided with rear end cap integrated connecting plate, the end face of connecting plate is provided with connection hole slot.
The material that described support adopts is aluminium.
The manufacturing process of described driving motor for electric automobile benzvalene form support, it comprises the following steps:
S1, cast frame blank;
Seam before S2, processing support;
S3, with before support seam location, with same tool sharpening support rear end bearing room.
The present invention has the following advantages:
Electric machine stand and rear end cap are integrated by the present invention, adopt integral type processing, eliminate rear end cap and support assembly process, simplify motor assembly technology, improve motor assembly precision, reduce the noise of system.
The invention solves the problem that axiality that conventional electric electric motor of automobile support and end cap adopt split type processing and exist is poor, positioning datum is unified, improves the axiality of support and front end housing, decreases rigging error.
Support casting technique of the present invention can realize, support rough-cast out after, seam before processing support, with seam location before support, processing machine base rear end bearing chamber, the same cutter of support seam and rear bearing room is processed, improve support precision, ensure that the axiality of seam and bearing chamber, reduce dynamical system noise, realize product seriation, standardization, General design.
The present invention adopts aluminum support, alleviates support weight, meets driving motor for electric automobile miniaturization and demand, improves the competitiveness of product.Adopt ripe casting technique, selected material is also convenient to be bought, concept feasible.Aluminum unsplit frame non-corrosive, meets environmental requirement.
