DEVICE FOR STEPLESS GEAR OF TORQUE MOMENT Russian patent published in 2013 - IPC F16H3/74 

FIELD: machine building.

SUBSTANCE: device contains housing (1), drive (2), driven (3), intermediate (4) and auxiliary (5) shafts. On drive shaft (2) there rigidly fixed are gear wheel (6) and differential pinion shaft installed perpendicular to drive shaft (7), which ends are provided with two conical gears (8) contacting the right (9) and the left (10) gears. Gear (10) is connected to gear (11), and gear (9) with tooth crowns from both sides is rigidly fixed on driven shaft (3). There is a loose gear (12) on driven shaft (3) which is differential pinion shaft on which two gears (13) are installed contacting with a pair of gears (9) and (14). Gear (14) is connected to gear (15). There are the following installed on intermediate shaft (4): gear (16) meshed with gear wheel (6), differential pinion shaft (17) and gear (18). On shaft (17) there two gears (19) are installed contacting gears (20) and (22). Gear (20) is rigidly connected with gear (21) which is in mesh with gear (11) via gears (31), (29), (30) and (32), and gear (22) is rigidly connected to gear (23) contacting gear (12). There are rigidly fixed gears (24) and (25) on auxiliary shaft (5). Gear (24) is in mesh with gear (15), and gear (25) is in mesh with gear (18). On guides (27) rigidly attached to housing (1) there is a base (26) of movable mechanism of elastic brakes of gear wheels, axes (28) in base (26) are retained by gears (29) and (30) which are in mesh with each other. Pairs of gears (29) and (31), (31) and (21), (30) and (32), (32) and (11) are interconnected by movable interaxle plates (33) and are also in mesh with each other. Axes of gears (31) and (32) are connected by springs (34), there are springs (35) and retainers (36) between housing (1) and base (26) on guides (27).

EFFECT: increasing efficiency and improving reliability of device.
