Reverse gear for routes

If, during stretching, the sliver outlet is designed in such a way that instead of the usual simple sliver, 2 or more slivers are stored in a can, either per can Λ 'i'richterrad with several funnels or for each can 2 or more i'richter wheels are used then it is necessary to give the cans, which take up the outgoing slivers, a reciprocating rotary motion instead of a uniform rotary motion.

To generate this reciprocating rotary movement from a uniform movement, differently designed so-called reverse gears are used.

The present invention relates to such a reverse transmission which in contrast to the previously known versions has the advantage that it consists of only a few individual parts and also contains spur-toothed wheels that are very easy to manufacture.

The uniform rotary movement initiated by a drive shaft is transformed into a reciprocating rotary movement aD output shaft in that the drive shaft carries a spur gear that is only toothed on half the circumference and which is in direct contact with only one of two tickles that are opposite each other in relation to the drive shaft stands, while the tickle, which is at the same time disengaged from the spur gear, is driven via gear reduction. The direction of rotation of the two tickles is thus reversed after every half revolution of the drive shaft or the spur gear, and consequently the drive shaft experiences

a reciprocating rotary motion.

In the accompanying drawing is an example of the subject of the invention shown in a schematic representation.

With (a) dfe uniformly driven shaft is shown. On this sits a spur gear with teeth only on half the circumference Κ.Λ). This is only in engagement with one of the "two tickles \ 2) and (3; "). The pinions (.2.) And (J>) sit on the output shaft (b; or (, & ♦) · On the same Shaft also sit the meshing wheels (.4) and

If, as shown, the spur gear (.1) is in engagement with the tickle (2), the tickle {3) and thus the output shaft (b; from the counterclockwise rotating drive shaft (a.) the drive via Kitzel {2) and the back gear (4) and (5) and also rotates in the counter-clockwise direction. When the drive shaft (a) of the spur gear (.1) engages in the tickle (.3) after half a turn, the pinion 0) and with it the output shaft ^ b) turn clockwise. The direction of movement of the output shaft (b) changes the direction of rotation after every half turn of the drive i / exle ^ a). The same applies analogously to an output shaft (b ^! ) Which is provided approximately as an extension of the axis of the tickle (2) or the cage (.4).

All wheels and especially the Had (, 1), which is only toothed on one side, are designed as spur-toothed cages. Not at all other mechanical parts, as they are with previously known Reverse gears are available.

Claims (1)

-Claim ^ Reverse gear for lines characterized in that the: ~ uniform rotary movement initiated by a drive shaft (.a) is converted into a reciprocating rotary movement of the output shaft (b) or (b ^f ) by the fact that the drive shaft (a) a spur gear (1) which is only toothed on half the circumference and which is in direct meshing engagement with only one of two in relation to the drive shaft (a; opposing tickles (2) or (3)), while that at the same time meshing with the gear (J) pinion (.3) or (2) via the gear reduction (4 ·) and driven jst.
