摘要： A gear assembly (1) with bidirectional continuous rotating speed regulation comprises a gearbox (7) provided with a primary shaft (2) and a secondary shaft (6). On said primary shaft (2) there is arranged an eccentric (3) that is connected with a device (9) for control this eccentric (3). Said device (9) provides a change of position of axis (11) of rotation of eccentric (3) relating to axis (10) of rotation of primary shaft (2). On said eccentric (3) there is rotationally arranged an output segment (4) that is connected by means of coupling member (5) with said secondary shaft (6). An outer guide (8) of said output segment (4) is arranged on said gearbox (7).

摘要： A mowing device for the treatment of vegetations is adapted for the attachment to a carrier and for the connection to a drive unit. The mowing device includes a frame (22), on which mowing spindles (7a, 7b) are mounted which are provided on one side with mowing blades and on the opposite side with distributing elements for the connection to transmission members. On the frame (22), a transmission mechanism for driving the mowing spindles (7a, 7b) is further positioned. The mowing spindles (7a, 7b) are arranged in two mutually parallel rows, defined by longitudinal lines (8, 9), located in a mutual distance separation (L). The mowing spindles (7a, 7b) of each row are interconnected by means of the ' transmission members. The centres of the mowing spindles (7a) of the first row on a line (8) are located in a mutual spacing (P). The centres of the mowing spindles (7b) of the second row on the line (8) are located in the mutual spacing (P). The centres of the mowing spindles of the second row are offset in the direction of the lines (8, 9) by a one-half P/2 of the spacing P with respect to the centres of the mowing spindles (7a) of the first row on the line (8). A connecting line of the centre of each mowing spindle (7a) of the first row on the line (8) with the centre of the immediately adjacent mowing spindle (7b) of the second row on the line (9) forms with parallel longitudinal lines (8, 9) an acute angle (a), for which the following applies: L tg a = P/2 The size of the angle a is in the range from 15 ° to, 60 °. The transmission mechanism for driving the mowing spindles (7a, 7b) comprises two transmission devices mounted side by side on the frame (22) and mutually connected. The first transmission device is arranged for the rotation in one rotational direction and is connected via transmission members with the mowing spindles (7a) of the first row on the line (8). The second transmission device is arranged as a reverse device for an optional rotation of the output shaft of the gearbox (2) in both rotational directions, and it is associated via transmission members with the mowing spindles (7b) of the second row on the line (9).

摘要： Travelling device (20) particularly for self-propelled mower comprises a frame (1) provided with several identical travelling units (21) arranged on its circumference. Each travelling unit (21) comprises a flexibly suspended travelling wheel (2) rotating on its horizontal and vertical axes. A motor unit (3) with a driving shaft (13) is arranged on said frame (1) for driving a working device and said travelling wheels (2). Said travelling wheels (2) are arranged in said travelling units (21) turnably on vertical axis in an unlimited angular range of 360°.
