Description

Electromotor and generator amature coupling arrangement

Technical field

This utility model relates to the mixed automobile current generator field of electricity, particularly relates to a kind of electromotor and couples dress with generator amature Put.

Background technology

Existing electromotor and engine crankshaft coupling arrangement typically have following several form:

(1) electromotor is positioned at the side of electromotor, and engine power output shaft is provided with belt pulley, by belt and generating The drive shaft of machine couples, and feature is easy for installation, and shortcoming is that volume is big, should not arrange in little structure space, and belt holds Easily skid；(2) be mounted directly the rotor of electromotor on engine crankshaft power output shaft, stator by the connection dish of electromotor with The housing of electromotor connects, and the diameter bearing capacity of the power output shaft of this structure engine bent axle should be greater than or equal to electromotor Load needed for rotor operating, and the operating dependence crankshaft bearing carrying of electromotor, the advantage of this structure is that volume is little, Low cost of manufacture；Disadvantageously, limited by engine structure, engine power is relatively big, and the power output shaft of bent axle is relatively thin, bent axle Power output shaft disclosure satisfy that the torsion needed for electromotor, but when can not meet the bearing capacity of generator operation, this structure without Method uses；Affected by the self structure of electromotor and electromotor, when generator amature is inclined with engine crankshaft bearing mounting distance Time remote, it is necessary on the power output shaft of engine crankshaft installing dynamo bearing, Cai Nengman again additional near the position of electromotor The operating of foot electromotor needs, but after being further added by dynamo bearing, dynamo bearing and two bent axles hold the same of sight alignment How heart degree ensures, this just become in industry required for solve the technical problem that, the additionally power output shaft of engine crankshaft Diameter is less than normal, it is impossible to there is a need to when meeting the operating bearing capacity of generator amature strengthen generator shaft, when strengthening generator shaft It is necessary between generator shaft and the power output shaft of engine crankshaft, take new method of attachment.

In the engine housing manufacturing technology with bent axle, engine crankshaft is passed through by left box body and the right case of electromotor Bearing positions, and forms two fulcrums, and generator shaft relies on bearing location to form the 3rd fulcrum, and by electromotor connection dish and Engine housing connects, and is connected in dish processing and installation process with electromotor at engine housing, in the margin of tolerance allowed, The axiality of generator shaft and engine crankshaft still can produce the tolerance of 0 ~ 30, if not taking corresponding technical measures, bent The coaxiality deviation of axle bearing and dynamo bearing sight alignment can cause in the running of electromotor, accelerates the mill of bearing Damage, the power output shaft of bent axle ruptures, and forms serious technological deficiency, it is therefore necessary to design one can eliminate two bent axles The manufacturing tolerance of sight alignment between bearing and dynamo bearing so that it is steady quality, length in service life generator shaft with send out Attachment means between motivation axle, meets the connection requirement of electromotor and engine crankshaft.

Summary of the invention

Goal of the invention of the present utility model:

The actual operation requirements of automobile is mixed according to plug-in extended-range electricity, the new-generation machine rotor coupling arrangement of design, should Coupling arrangement is the connecting mode that coordinates of coning sleeve and taper head, thus realizes the power generation process of electromotor, it is ensured that generating The requirement of unit assembly precision, it is achieved the most effectively transmission of power, meets the use requirement of generating set.

The technical solution of the utility model is:

Provide electromotor and generator amature coupling arrangement, including motor body and setting on motor body Electromotor connection dish, the internal crankshaft bearing arranged of motor body, the power output shaft of engine crankshaft, and electromotor is fixed Son and rotor, the internal dynamo bearing arranged of generator unit stator, generator shaft cross-under in dynamo bearing, described generating The outer end of arbor is set to external taper face and is connected with the adapter sleeve of generator amature, and the inner of generator shaft is against dynamo bearing Medial surface extends internally and is set to inner conical surface type, and the upper end of the power output shaft of described engine crankshaft is male cone (strobilus masculinus), and with The inner conical surface of generator shaft the inner is connected, and electromotor connection dish is extended with fixed sleeving to application generator unit stator, sends out Motor bearings is assemblied in fixed sleeving, and generator unit stator is sleeved on fixed sleeving.

The power output shaft upper end of engine crankshaft is provided with threaded connection hole, and described generator shaft is provided centrally with Central through hole, is connected by adapter sleeve between generator shaft with generator amature, the fixing bolt handle arranged in central through hole Together with generator shaft connects with adapter sleeve confine with the power output shaft of engine crankshaft.

The beneficial effects of the utility model are:

This utility model overall construction design is reasonable, and engine crankshaft is passed through bearing by left box body and the right case of electromotor Location, forms two fulcrums, and generator shaft relies on bearing location to form the 3rd fulcrum, and passes through electromotor connection dish and start Cabinet bulk connects, and is connected in dish processing and installation process with electromotor at engine housing, in the margin of tolerance allowed, and generating The axiality of arbor and engine crankshaft still can produce the tolerance of 0 ~ 30, by the power output shaft of engine crankshaft is prolonged Extend the power output shaft being attached being formed longer engine crankshaft at dynamo bearing with generator shaft, longer power Output shaft can output natural torsion elastic, utilize the elasticity of flexure effectively to eliminate, engine crankshaft and the three of generator shaft In the case of individual fulcrum generation minor departures so that it is can steady operation, bearing wear, Analyse for Cracking of Engine Crankshaft will not be produced Defect.

By overstriking generator shaft and then increase dynamo bearing, it is possible to make generator shaft fully meet generator operation Load, add the service life of bearing.

This structure effectively achieves in the case of the power output shaft of engine crankshaft is partially thin, overstriking electromotor Axle, increases dynamo bearing, fully meets the carrying demand of generator amature operating, adds the use of dynamo bearing In the life-span, make that this system structure is stable, service life is long, and need not be further added by the shaft coupling that other structures are more complicated, reduce Cost, solves a kind of technical barrier that electromotor is connected with electromotor.
