The invention relates to mechanical engineering and can be used in gears with parallel shafts.

The aim of the invention is to expand the kinematic transmission capabilities by sequentially connecting the driven shafts to the drive shaft.

ha drawing shows a gear transmission.

A gear transmission contains parallel drive shaft I and driven shafts 2.3, mounted on shafts 2.3 in cylindrical gears 4.5 which are displaced one relative to the other by the amount t of end planes and mounted on the drive shaft 1 STI with gear wheels 4, 5. The width B of gear 6 is chosen equal to

b t; ,

where b is the width of the wheels 4,5j

Z t. - the sum of the displacements t of the wheels of the adjacent driven shafts relative to each other.

In the variant shown in the drawing, t, t, the drive shaft 1 is connected to the engine 7, and the driven shafts 2.3 are connected to consumers 8.9, for example, hydraulic pumps. The driven shafts 2.3 are housed in a housing (not shown) around the driving shaft 1 and are not kinematically interconnected.

On wheels 4.5 and gear 6, corresponding chamfers of 1 O are made at the respective ends to soften the blows when they are engaged. at

The transmission works as follows.

When rotating the shaft 1 by the axial movement of the gear 6 (in the drawing

to the left) it is brought into engagement with the wheel 4. The driven shaft 2 begins to rotate, driving consumer 8. By further axial movement of gear 6 in the same direction, it engages the wheel 5. It begins to rotate the driven shaft 3, driven consumer 9. As a result, two shafts 2, 3 work simultaneously. Shafts 2, 3 are turned off by reverse axial movement of gear 6.

The number of driven shafts (and, respectively, offset wheels) can be arbitrary. The amount of displacement t is determined not only by the condition that the wheels are engaged in successive engagement, but also by the working load on the corresponding driven shaft, i.e. is calculated.
