FIELD: transport.SUBSTANCE: driving (4) and driven (5) conical gear wheels is made integral with their shafts and installed among themselves with reversal of rotation. In the casing (1), each of gear wheels is mounted on two bearing assemblies. Area of engagement of gear wheel crown gears is located between front and rear bearing assemblies of shafts. The casing comprises front wall bent with upper part forward tilt according to position of gear wheels installed with specified angle between axes, and two covers (2, 3). In the boring of front wall lower part, roller bearing (6) of driving gear wheel (4) shaft front support is installed. In the boring at the inner side of lower cover, double-row ball bearing (10) of driving gear wheel (4) shaft rear support is installed. Inside the boring of casing in the front wall lower part, roller bearing (19) of driving gear wheel (5) shaft front support is installed. In the boring of lower cover, double-row ball bearing (22) of driven gear wheel (5) shaft rear support is installed.EFFECT: invention is intended for changing over direction of tail shaft axis and torque transmission from main gearbox to tail gearbox.2 cl, 3 dwg |
