Abstract

The utility model relates to a start motor, in particular to a start motor for a minitype universal petrol engine. The start motor for petrol engine comprises an end cover, a casing, a rotor, a rotor commutator, a carbon brush bracket and a hand power star disk. The start motor for petrol engine is characterized in that the hand power star disk is arranged inside the end cover; the shaft end of the rotor shaft of the start motor extends out of the end cover; a hand power start connecting clutch is arranged on the shaft end; the end cover of the start motor is directly arranged on the crank case of an engine; the end cover is directly arranged on the casing. The utility model has the advantages of the double functions of manual start and electrical start, reasonable convenience start and practicality.

Description

Petrol Engine Using For Starting Motor

Technical field

The utility model relates to a kind of starting motor, specifically is a kind of small utility gasoline engine starting motor.

Background technique

Existing general gasoline engines generally adopts the hand pull starting-up mode to start, and is comparatively inconvenient, particularly winter, starts difficulty more, and when going up, hand pull starting-up mode and structure are more unreasonable when general gasoline engines is used in dilly (as the petrol engine scooter etc.).Producer is now also arranged in order to overcome above-mentioned defective, starting motor has been installed on general gasoline engines, but because its structure adopts the split overlapping to install, earlier starting motor is directly installed on the motor, its rotor is directly installed on the engine crankshaft, cause two deficiencies: the one, structure is very complicated, the Installation and Debugging difficulty; The 2nd, because rotor is directly installed on the bent axle, cause to need only engine running, starting motor is and then running just, and commutator on the starting motor and carbon brush wearing and tearing are very fast, and operating life is very short.

Summary of the invention:

The purpose of this utility model is at the deficiencies in the prior art, and a kind of collection hand starting simple and compact for structure, flexible and convenient to use and the electric Petrol Engine Using For Starting Motor that starts one are provided.

The technical solution of the utility model is as follows:

A kind of Petrol Engine Using For Starting Motor, comprise housing, end cap, rotor, rotor commutator, the carbon brush support, the hand pull starting-up dish, it is characterized in that: the hand pull starting-up dish is installed in the end cap, and be sleeved on the rotor shaft, have one on the hand pull starting-up dish and start boss, starting motor rotor shaft axle head stretches out end cap, be equipped with one on the axle head and pull startup connection clutch, hand pull starting-up connects on the clutch Returnning spring, centrifugal and startup boss, hand pull starting-up connects the startup boss of clutch and the startup clutch engagement of petrol engine motor, and the startup boss on the hand pull starting-up dish is connected clutch engagement with manually booting.

Starting motor end cap of the present utility model is directly installed on the engine crankcase, and end cap and shell are directly installed.

The utility model is owing to adopted one to pull startup connection clutch, when hand pull starting-up, the rotating force of hand pull starting-up dish connects clutch apart from passed to hand pull starting-up by the hand pull starting-up dish, passes to the engine start clutch again, thereby the drive engine crankshaft is to reach the purpose of startup; When electricity starts, because it is to be directly installed on the starting motor rotor shaft that hand pull starting-up connects clutch, therefore, during revolution, hand pull starting-up connects clutch and also rotates, drive engine rotation, simultaneously, owing on hand pull starting-up connection clutch, be equipped with centrifugal, when starting motor begins to rotate, centrifugal under action of centrifugal force, automatically and the hand pull starting-up disk detachment, thereby do not interfere with the hand pull starting-up dish.The utility model integrates hand pull starting-up, electricity starts, and is rational in infrastructure, easy to use.

The drawing explanation:

Fig. 1 is the utility model structural representation.

Fig. 2 connects the clutch configuration schematic representation for hand pull starting-up.

Fig. 3 is the A-A sectional view of Fig. 2.

Fig. 4 is the rear view of Fig. 2.

Embodiment:

As Fig. 1,2,3, shown in 4, a kind of Petrol Engine Using For Starting Motor, comprise housing 12, end cap 9, rotor 11, rotor commutator 18, carbon brush support 4, hand pull starting-up dish 3, it is characterized in that: hand pull starting-up dish 3 is installed in the end cap 9, and be sleeved on the rotor shaft 5, have one on the hand pull starting-up dish 3 and start boss 14, starting motor rotor shaft 5 axle heads stretch out end cap 9, be equipped with one on the axle head and pull startup connection clutch 2, hand pull starting-up connects on the clutch 2 Returnning spring 21, centrifugal 7 and startup boss 13, the startup boss 13 that hand pull starting-up connects clutch 2 cooperates with the startup clutch 1 of petrol engine motor, and the startup boss 14 on the hand pull starting-up dish 3 is connected clutch 2 and cooperates with hand pull starting-up.

Starting motor end cap 9 of the present utility model is directly installed on the crankcase 8 of motor, and end cap 9 is directly installed with shell 12, and bearing 15,16 is installed in end cap and the shell.

The dribbling of the utility model hand pull starting-up has a Returnning spring 19 and hand pull starting-up rope 17, pull handle 24.

It is fixing by nut 20 with rotor shaft that hand pull starting-up of the present utility model connects clutch 2.

The utility model since engine start clutch 1 with manually boot dish and increased by one in the middle of 3 and pull startup and be connected clutch 2, when pulling starts pull

handle

24,3 rotations of hand pull starting-up dish, hand pull starting-up dish 3 rotation backs are blocked centrifugal 7 back drive hand pull starting-up by startup boss 14 and are connected clutch 2 rotations, hand pull starting-up connects clutch 2 and blocks 1 rotation of centrifugal 6 back drive engine clutch by starting boss 13, engine start clutch 1 drives bent axle 22 and rotates, ato unit then, behind the ato unit centrifugal 6,7 throw away automatically, thereby be connected clutch 2 breaks away from hand pull starting-up, centrifugal 7 and 14 also disengages simultaneously, when electricity starts, 11 energisings of starting electrical machinery rotor begin rotation, drive hand pull starting-up and connect clutch 2 rotations, the bent axle 22 that drives casing 8 simultaneously rotates, and ato unit, simultaneously when the 11 energising rotations of starting electrical machinery rotor, centrifugal 7 of connecting on clutch 2 of its hand pull starting-up throws away automatically, thus avoid with the hand pull starting-up dish on startup boss 14 interfere.
