Description

one

Invention from engine to engine building, in particular to starting devices.

Known starting devices for the engine internal stor "and containing an electric motor, the shaft of which is equipped with coaxially located with the shaft with six gears, and the mechanism of manual starting from the bar 6aiHOiM.

In the well-known starting devices of the fur, the manual start-up model is performed separately from the electric motor and represents a separate unit with a separate approach to the flywheel. In connection with ETI1M, known starters of the construc- tigio are complex and have a larger envelope.

The proposed device differs from the known ones in that the drum is mounted coaxially with the KOHueHTpnMHo electric motor, which is attached to the shaft, the clutch connecting it to the drum or the shaft of the electric motor, respectively, and equipped with a brake (M for automatic engagement.

Such an arrangement ensures the simplification of the design and reduction of the dimensions.

The drawing shows the proposed starting device for the internal combustion engine in section.

The device contains an electric motor /, for example, with remote control m. The electric motor shaft 2 is provided with an oooosly disassembled with the NI.M. drive shaft 3, connected with a screw spline 4 with a gear wheel 5. Gear 6 is located on the shaft 2, installed in support 8 of the housing 8. Aligned with shaft 2 and concentrically with the primitive roller 5, set the drum 9. manual start mechanism. The drum has a cable 10 and return guns //. The whole mechanism of the manual start is placed in the housing 8. The drive roller 3 is equipped with a gear clutch 12, which connects it to the shaft 2 of the electric motor 1 with the 1st gear and 6 gears il or to the harness i 9 with the P-11 gears 13.

In the main housing 14, a brake 15 is installed for automatically introducing gear 5 into engagement with the gearing of the swivel shaft) (not shown in the drawing).

The device works as follows.

When starting the internal combustion engine

electric motor / .. coupling 12 is installed with the lever 16 in the position at which

the roller 3 is connected to the shaft 2 of the electric motor or manually started with 6 apai6a oi 9. In both cases, the torque from the shaft 2 or drum 9 is transmitted to the roller 5 and then to the gear wheel 5. So the KFV gear 5 slows down the brakeol 15, then, due to the screw slot 4 of the joint between shaft 3 and gear 5, the latter is mixed axially along the roller 3, the entrance to the rim from the flywheel rim. In this way, the rotation of the engine crankshaft is released inside its combustion and bunch of the latter.

After starting the engine, gear 5 is screwed onto the drive roller 3, disengaged from the flywheel of the flywheel, the gear like gear 5 has revolutions greater than that of the drive roller 3.

Subject invention

1. Starting device for an internal combustion engine containing an electric motor whose shaft is coaxially disposed with a drive motor with a gear, and a manual start mechanism with a drum, characterized in that, in order to simplify to: power | K | Ts1I. and to reduce overall dimensions, the drum is mounted coaxially with the shaft of the K01 electric motor in the center of the drive roller, onabzhennno, with a clutch connecting it respectively to the bar-bath or the shaft of the electric motor.

2. Device 1PO P. 1, characterized in that the gear is connected to the drive shaft iKOM with a new screw-spline connection and is equipped with a brake for automatic leading into the target.
