Abstract

The invention relates to mechanical engineering. The purpose of the invention is to increase the reliability of operation. The gearbox has a wide range of gear ratios in direct drive to the actuator. The radially concentric circles on the end surface of the cylindrical driven pulley 10 are hollows 11. The driving pulley is a gear wheel 4, on the side surface of which there is a conical gear wheel 5 interacting with the driving shaft 2. On the outer surface of the shaft 2 there are longitudinal the tooth 3, and inside it axially, the rail 7 moves to which the drive pulley is fastened to the cable drive joint 6. The gearshift mechanism is made in the form of a slider 1 with a locking latch 15 of the selected gear, which interacts with the rack 7. 7 Il. (L

Claims (1)

Claim A gearbox comprising a housing, drive and driven shafts installed in it, the axes of which are perpendicular to each other, mounted on the drive shaft with the possibility of axial movement by the drive pulley and on the driven shaft by the driven pulley, the pulleys are interconnected by teeth made on the drive pulley , and troughs made in concentric circles on the surface of the driven pulley, a fixing rod and a switching mechanism, which are designed to ensure that, in order to increase reliability, one of the ends of the drive pulley is made with protrusions, and the switching mechanism is made in the form of a hollow slider axially movable, in which the drive shaft 6 is mounted rotatably, made hollow with conical depressions at one of the ends to interact with the conical protrusions of the drive pulley and rail for communication with the drive pulley, by means of a universal joint hinge mounted inside the drive shaft. 7 ': j.
