Abstract
The utility model relates to a starting motor which is used on universal gasoline engines, comprising a casing, a stator, a rotor, and a back end cap. One end of a core shaft of the rotor, which is fixedly provided with a rectification slip-ring is supported on the back end cap through a bearing, and an axial center hole of the rectification slip-ring, which is engaged with a mandrel is a step hole. A boss is arranged in the center of the inner side of the end surface of the back end cap, and holes are opened in the boss. The boss is positioned in the large hole of the rectification slip-ring step holes, and one end of the mandrel, which fixes the rectification slip-ring, is supported in the hole of the boss through a bearing. The axial size of the starting motor can be reduced at the premise of no affection on the performance of the starting motor, thereby being beneficial for the installation of the starting motor on crankcase bodies of gasoline engines.
Description
Technical field
The utility model relates to a kind of starter motor that uses on general gasoline engines.
Background technology
Starter motor is used widely on small utility gasoline engine, and it is fixed on the crankcase of gasoline engine and is positioned at outside the crankcase.Gasoline engine with starter motor comprise shell, in shell stator, between stator rotor and be positioned at the rear end cap of shell one end, one end of rotor mandrel is equipped with the rectification slip ring, the rectification slip ring can rotate (as shown in Figure 2) with mandrel thereby the rectification slip ring is fixed on the mandrel by its axle center hole and mandrel interference fit.Rear end cap is provided with boss in its end face outer side center, in boss, offer porose, rotor mandrel by bearings in this hole, thereby mandrel one end is supported on the rear end cap.The boss that the rear end cap end face is provided with its objective is in order to increase the thickness of rear end cap, so that mandrel can be supported on the rear end cap reliably.But this of starter motor kind of structure makes that the axial dimension of starter motor is bigger, and the installation site that offers starter motor owing to Gasoline Engine is limited, so this will influence the installation of starter motor on the gasoline engine crank casing.
The utility model content
The purpose of this utility model provides a kind of gasoline engine starter motor, under the prerequisite that does not influence the starter motor performance, makes the axial dimension of starter motor as far as possible little.
Gasoline engine starter motor described in the utility model, comprise shell, the stator in shell, the rotor between stator and be positioned at the rear end cap of shell one end, the end that the mandrel of rotor is fixed with the rectification slip ring by bearings on rear end cap, the axle center hole that the rectification slip ring cooperates with mandrel is a stepped hole, the inboard center of rear end cap end face is provided with boss, offer porose in the boss, and boss is arranged in the macropore of rectification slip ring stepped hole, the end that described mandrel is fixed with the rectification slip ring by bearings in the hole of this boss.
The utility model is because the axle center hole that the rectification slip ring cooperates with mandrel is a stepped hole, and the boss that will offer the mandrel supported hole is arranged on the end face inboard of rear end cap, and this boss is arranged in the macropore of rectification slip ring stepped hole, like this under the situation that does not change other accessory size of starter motor, the axial dimension of rear end cap is reduced, thereby the axial dimension of starter motor is reduced.Because other accessory size except that rear end cap does not change, so the performance of starter motor can not be affected.
The utility model under the prerequisite that does not influence the starter motor performance, is reduced the axial dimension of starter motor, thereby helps the installation of starter motor on the gasoline engine crank casing owing to have this kind structure.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 looks generalized section for gasoline engine described in the utility model with the master of starter motor;
Fig. 2 looks generalized section for existing gasoline engine with the master of starter motor.
Embodiment
As shown in Figure 1, this gasoline engine with starter motor comprise shell 4, in shell 4 stator 3, between stator 3 rotor 2 and be positioned at the rear end cap 5 of shell 4 one ends, mandrel 1 one ends of rotor 2 are fixed with rectification slip ring 6, rectification slip ring 6 is by axle center hole on it 9 and mandrel 1 interference fit, and this axle center hole 9 is a stepped hole; Be provided with boss 8 at the inboard center of rear end cap 5 end faces, offer porose in the boss 8, and this boss 8 is arranged in the macropore of rectification slip ring 6 stepped holes, and the end that described mandrel 1 is fixed with rectification slip ring 6 is supported in the hole of this boss 8 by bearing 7, thereby mandrel 1 this end is supported on the rear end cap 5.
Claims (1)
1. gasoline engine starter motor, comprise shell (4), be positioned at the stator (3) of shell, rotor between stator (2) and be positioned at the rear end cap (5) of shell one end, the end that the mandrel of rotor (1) is fixed with rectification slip ring (6) is supported on the rear end cap by bearing (7), it is characterized in that: the axle center hole that the rectification slip ring cooperates with mandrel (9) is a stepped hole, the inboard center of rear end cap end face is provided with boss (8), offer porose in the boss, and boss is arranged in the macropore of rectification slip ring stepped hole, the end that described mandrel is fixed with the rectification slip ring by bearings in the hole of this boss.
