CYLINDRICAL REDUCTION GEAR Russian patent published in 1994 - IPC

FIELD: transport engineering. SUBSTANCE: first body 19 is located on one of cylindrical wheels 17, first brake disks 20 are based on body 19. Second body 22 is fastened inside reduction gear case 11, second brake disks 23 are based on body 22. First and second brake disks 20 and 23 are alternately located. Cylindrical wheel 17 which has first disk body 19 is axially moved by pressure pin 38 passing through case 11 and driven from outside. This displacement surpasses the force of spring 40. Brake disks 20 and 23 are compressed between cylindrical wheel 17 and bearing surface 39 in reduction gear case 11. The structure has double-arm lever 34 which one arm is controlled by the driver, and the second arm is adjacent to pressure pin 38. Besides a hydraulic drive used for braking during motion the structure has a mechanical drive, for example, in the form of a brake lever connected to cable 36, which is used as a stopping brake. EFFECT: improved structure. 9 cl, 8 dwg
