    4 00 SP The invention devotes itself to mechanical engineering, in particular to automotive windshield wiper drives. A gearmotor is known, comprising a housing, having a bottom and a lid, a drive shaft located therein with two sections of an oppositely directed worm thread, having an equal number of entries more than one, located perpendicular to the driven shaft, carrying the driven gear rigidly fastened on it, Two identical double gears mounted on the axles fixed in the bottom and interacting respectively with the worm-cut sections of the drive shaft and the driven gear, and the ratio of the number of teeth in each of the double gears Eren equal to the number of entries threaded. The bottom does not have a hole. G1 A disadvantage of the known gear motor is the increased labor intensity of the assembly. This is due to the fact that the driven shaft, which carries the driven gear, is installed in the housing cover; therefore, during the assembly process, it is not possible to engage the driven gear simultaneously with two double gears in one go. As a rule, it is necessary to repeatedly remove one of the double gears and rotate it at a certain angle until the teeth of the driven gear will be aligned with the depressions of the corresponding toothed rims of the double gears. The purpose of the invention is to reduce the labor intensity, assembly. This goal is achieved by the fact that in a gear motor containing a housing having a bottom and a lid, a drive shaft located in it with two sections of oppositely directed worm cutting, having an equal number of entries greater than one, the driven shaft located perpendicular to the drive shaft and carrying the driven gear rigidly fixed on it, two identical double gears mounted on the axles fixed in the bottom and interacting respectively with the worm-cutting sections of the drive shaft and the driven gear, and the ratio of the numbers The teeth of each of the double gears is equal to the number of black cutting cuts, there is a hole in the bottom, in which the drive shaft is installed, and the drive shaft is placed between the driven gear and the steering wheel. The drawing shows the proposed motor gearbox, a general view. The gear motor includes a housing 1, having a bottom 2 and a cover 3, a drive shaft 4 with two sections 5 and 6 of a screw-cutting, an actuator 7, a driven shaft I. with a rigidly mounted driven gear 9 and two installed double gears on axes x 12 and 13. Double gear 10 contains gear rims 1 and 15, and gear 11 gear rims 16 and 17, with rims 14 and 16 interacting respectively with sections 5 and 6 of the worm-cutting drive shaft 4, and rims 15 and 17 - with the driven gear 9. The ratio of the number of teeth in the crowns of each of the double gears is equal to the number in chervny cuts. In the bottom 2, there is a hole in which a shaft 1-1 of the shaft 8 is installed, and the shaft 4 is placed between the driven gear 9 and the cover 3 attached to the body 1 by studs 18, screwed into the threaded holes 19. The hole 20 is threaded 3 , serving to install the free support 21 of the driven shaft 8, and the holes 22 and 23, which include the axes 12 and 13. The gear motor operates as follows. The actuator 7 rotates the drive shaft 4, sections 5 and 6 of the worm-threading of which through the gear rims 14 and 15 and through the rims 16 and 17, which interact with the driven gear 9, transmit the rotation of the latter and, therefore, the driven shaft 8. They are in the following way. In the hole of the bottom 2, the drive shaft 8 is installed, carrying the driven gear 9, then the drive 7 is installed with the drive shaft 4. The two double gears 10 and 11 are mounted on axles 12 and 13 so that they engage with the driven tester 9 serrated rims w 1 and 17, as well as with sections 5 and 6 of the screw-cutting of the drive shaft with the serrated rims 14 and 16, respectively. Then the housing 1 is closed with a knuckle 3 and the studs 18 are screwed in. The proposed motor-reducer reduces the complexity and duration of the technological assembly cycle.
