    An internal combustion engine starter motor of the kind wherein the pinion gear wheel assembly includes a roller clutch. The small diameter drive sleeve of the clutch is encircled by an annular seal and the seal engages the sleeve and an annular barrier member, the barrier member sealingly engaging the housing of the starter motor at its outer periphery.

    one
    The invention relates to the field of engine-building, in particular to starters for starting internal combustion engines.
    Starters are known for internal combustion engines 5, comprising a housing and an electric motor on whose drive shaft an actuator is mounted. The drive is made in the form of a gear, an elongated sleeve and a roller clutch of a free-wheeling stroke. The starter contains a helical cylindrical return spring, which, through a stop on the sleeve, fixes the drive in the initial position, an annular sleeve and an annular seal. 15 The seal covers the outer cylindrical surface of the sleeve and is tightly connected to the sleeve, which is tightly connected to the housing. The clutch consists of a cup-shaped leading cage, the diameter of which is 20 meters of the outer surface is greater than the diameter of the outer cylindrical surface of the sleeve, and cam surfaces are made on the inner surface, the inner cage and 25 rollers spaced between the cages and pressure springs 1.
    The lack of starters of the type described is the low degree of sealing of the starter. This is caused by
    design of the parts of the starter, serving to secure the ring seal and return spring.
    The purpose of the present invention is to improve the sealing of the starter.
    To achieve the goal, a return spring is placed on the outer cylindrical surface of the sleeve between the stop and the sleeve to press the sleeve against the outer part of the sleeve.
    FIG. 1 shows a longitudinal section of a starter} in FIG. 2 shows, on a larger scale, a portion of the image of FIG. 1 in FIG. 3 shows a longitudinal section of a starter (the second embodiment); in fig. 4 shows a longitudinal section of a starter (third embodiment); in fig. 5 shows, on an enlarged scale, an embodiment of an annular seal of a starter.

    The starter includes a housing 1, at one end of which there is a bolt 2 partially covering the housing. In case 1, a bearing 3 is fixed on the bearings on the bearings, which has a drive shaft 4, one of the bearings 5 being installed in KpbsiiKe
    [2]
    2. The electric motor consists of a core 3 and a stator 6. The shaft 4 of the cor 3 has a smooth section 7 and a section with spiral slots 8. On the shaft 4 there is an actuator 9 containing a gear 10 and a roller clutch free running 11. The coupling 11 has an elongated sleeve 12, The inner surface of which is provided with spiral slots, which interact with the spiral slots 8 of the shaft 4. At the end of the sleeve 12, similar to the bearing 5, is integrally formed with the sleeve, the leading ring 13 is differently shaped. with internal clips 14 th muff you. Cam surfaces 15 are made on the inner surface of the drive casing 13. Between the collars 13 and 14, rollers 16 and pressure springs are mounted, which press the rollers 16 to cam surfaces 15. Casing 1 holds the coupling parts inside the drive casing 13.. The mechanism that drives the drive 9 and the initial position In the working mode, it can be made in various variants. In the variant shown in FIG. 1, an electromagnet 18 having a pair of diametrically opposite poles is fixed in the body 1 (only one shows an electromagnetic measurine connected to the electromagnet 18) 9 and the disk 20, which rests on the end of the sleeve 12. When the electromagnet 18 is triggered, the measurine 19 moves the actuator 9 in the direction of the stop 21. In order to eliminate the ingress of dust into the body 1, dirt, dust, etc., case 1 has a shoulder 22, on which a gasket 23 is installed, pressed against the shoulder by an annular sleeve 24. The sleeve 24 has a central hole through which the sleeve 12 passes. At the edge of the sleeve 24 there is a tightly connected ring seal 25 which seals the sleeve 12 and seals starter. On the outer cylindrical surface 26 of the sleeve 12 a helical cylindrical return spring 27 is placed, which with one end is pressed against the seal 25 (shown in FIG. 2) and the other against the stop 28 on the sleeve 12, the Starter, having another variant of the mechanism for moving the drive, is shown Fig. 3, Electromagnet 29 for moving the actuator 9 is placed outside the housing 1 and connected to the actuator 9 by means of a rigid lever 30. The third starter variant shown in Fig. 4 differs from the previous one in that the lever 31 is elastic and contains two plates 32 and 33, Ring u the density 34 can be tightly connected to the opposite wall of the annular sleeve 35, for example, glued, as shown in FIG. 5, the starter operates as follows, the actuator 9 moves from the initial position to the working position by means of an electromagnet 18 (fig.) or 29 (fig , 3 and FIG. 4). Spiral splines 8 provide transmission of rotation from core 3 to gear 10. Drive 9 returns to its original position under the action of a return spring 27. Roller clutch 11 free running allows gear 10 to rotate freely in one direction. An O-ring seal 25 (Figs. 1-4) or 34 (Fig. 5) interacts with the outer cylindrical surface 26 of the sleeve 12 and ensures that the starter cavity does not penetrate into it from foreign substances at various stages of operation. The described starter device for an internal combustion engine provides a high degree of sealing. This is due to the fact that the return spring is located on the outer cylindrical surface of the sleeve and constantly presses the sleeve, on which the annular seal is fixed to the starter body part. A starter motor for an internal combustion engine, comprising a housing, an electric motor with a drive shaft, an actuator mounted on it, made in the form of a gear, an elongated sleeve and a freewheel roller clutch, a helical coil return spring that locks the actuator through the stop on the sleeve. an annular sleeve and an annular seal that encloses the outer cylindrical surface of the sleeve and is tightly connected to the sleeve, which, in turn, is tightly connected to the body, and the couplings consists of a cup-shaped leading cage, the diameter of the outer surface of which is larger than the diameter of the outer cylindrical surface of the sleeve, and cam surfaces are made on the inner surface, the inner cage and 1 / F between the cages of the rollers and the clamping springs are different. to improve sealing, the return spring is placed on the outer cylindrical surface of the sleeve between the stop and the sleeve to press the sleeve against the outer part of the sleeve to the body.
