Abstract
The utility model relates to a starting motor for a universal gasoline engine, which comprises a stator, a rotor, a housing body, and a carbon brush bracket. The utility model is characterized in that a rotor shaft is directly sheathed on a crankshaft of a gasoline engine; a commutator of the rotor faces the crankshaft of the gasoline engine; the carbon brush bracket is installed via the reverse side; the commutator and the carbon brush bracket is positioned in a hollow cavity of a hand pulling starting clutch; the rotor shaft is a hollow shaft which is fixed with the crankshaft via a screw stud. Because the utility model utilizes the hollow cavity of the hand pulling starting clutch of an original motor, the size is small; the stator is made of Nd-Fe-B rare earth magnetic steel, so the enough starting moment output can be ensured at the time of starting. The utility model is also connected with a rectifying voltage stabilizer connected with a battery jar, and the rectifying voltage stabilizer can be used for charging the battery jar.
Description
One, technical field
The utility model relates to a kind of motor, particularly a kind of general gasoline engines starting motor.
Two, background technique
Adopt the mode of hand pull starting-up the existing general gasoline engines (as the power of mowing machine, chain saw, gasoline engine generator group, petrol engine scooter etc.), very inconvenience during startup, particularly in winter, pull repeatedly and could start, if be used on the petrol engine scooter, hand pull starting-up is more inconvenient.The automatic starting motor of the petrol engine of Chu Xianing generally adopts high-speed electric expreess locomotive in the market, again through gear reduction and free wheel device, start after the enable switch moment of torsion passed to bent axle, like this, structure is very complicated, and need to change casing, investment is big, and the cost height also has a kind of employing and the coaxial mounted method of bent axle, but because it is to adopt the built-in structure of carbon brush support, its a whole set of carbon brush support and rotor commutator are all in motor inside, and volume is just excessive like this, usually exceeds usage requirement.
Three, summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of simple and reasonable, improved small utility gasoline engine starting motor on former hand pull starting-up motor that volume is little is provided.
The technical solution of the utility model is as follows:
The utility model comprises housing, stator, rotor, carbon brush support, it is characterized in that: rotor shaft directly is sleeved on the gasoline engine crank, and rotor commutator is contained in former engine hand pulling and starts in the cavity of clutch towards bent axle, and stretch out housing, to reduce the motor volume.
Carbon brush support reverse side of the present utility model is installed in the outside of motor attachment face, and is located in the cavity of former engine hand pulling startup clutch.
Rotor shaft of the present utility model is a hollow shaft, is fixed on the bent axle with stud bolt, and original hand pull starting-up clutch can be installed in the stud bolt other end, like this, can keep original hand pull starting-up performance.
Stator of the present utility model adopts the NdFeB rear-earth magnet steel, enough starting torque output is arranged, with direct driving bent axle in the time of can guaranteeing to start.
Starting motor of the present utility model has also connected a rectifying pressurizer, and links to each other with storage battery.Rectifying pressurizer is made up of rectification circuit, switching circuit, detection control circuit.Behind the starting motor motor; rotor rotates continuously, and at this moment, starting motor uses as generator; the electricity that sends is through the rectification circuit rectification; become direct current, the switching circuit of flowing through again charges to storage battery; when detecting control circuit and detect battery voltage and be higher than rating value; detect control circuit control switch circuit and disconnect, stop charging, with the protection storage battery storage battery.
The utility model has adopted the coaxial mounting type of motor rotor axle and bent axle, and has made full use of former hand pull starting-up clutch cavity, and volume is little, has guaranteed the installation sealing of changement simultaneously again; Stator adopts the extremely strong Nd-Fe-B magnet steel of magnetic intensity, therefore, has guaranteed the high pulling torque requirement that the coaxial installation of bent axle is required; This starting motor uses as generator, in the starting motor circuit, has added rectifying pressurizer, is the storage battery charging; The utility model can possess hand pull starting-up simultaneously and start dual mode automatically.
