The present invention relates to a device of angular gears for oscillatingly moving mower knives, comprising a transmission housing (1), input shaft (35), which is inserted into the transmission housing (1) through the housing opening (34), the rotor (4), which is installed in transmission housing (1) for rotation around the first axis of rotation (X) using at least one first bearing (6), while the rotor (4) has a receiving chamber (7) with a receiving hole (8). The device of angular gears also includes a crankshaft (5), which is inserted through the receiving hole (8) into the receiving chamber (7) of the rotor (4) and installed in the receiving chamber (7) with the possibility of rotation around the second axis of rotation (Y) with the help at least one second bearing (20), a drive element (10), which without the possibility of rotation is connected to the rotor (4) and mounted for rotation around the first axis of rotation (X) by means of at least one third bearing (13), and supporting means (15), which are housed in the housing (1) Transmissions and which is supported axially third bearing (13), wherein the support means (15) is detachable fastened to the housing (1) of the transmission. The invention is characterized in that the second axis of rotation (Y), around which the crankshaft (5) is rotatably mounted, is offset radially relative to the first axis of rotation (X), around which the rotor (4) is rotatably mounted, and the input shaft (35 ) is installed in the transmission housing (1) with the possibility of rotation around the third axis of rotation (Z), located at an angle to the first axis of rotation (X), using at least one fourth bearing (39).Настоящее изобретение относится к устройству угловых зубчатых передач для колебательно движущихся ножей косилки, включающему корпус (1) трансмиссии, входной вал (35), который вставлен внутрь корпуса (1) трансмиссии через отверстие (34) корпуса, ротор (4), который установлен в корпусе (1) трансмиссии с возможность
