Definitions

  • the innovation relates to a device for play-free forwarding and, if necessary, converting rotary movements according to the preamble of claim 1.
  • a drive device for backlash-free conversion of a rotary movement into a linear movement by means of a toothed belt and a drive gearwheel engaging with it is known, which is used for a precision drive, in particular for the rapid and repeatable adjustment of tools, tool tables, Handling devices or robots is suitable, wherein at least one rack extending in the direction of adjustment is provided, with which the toothed belt is constantly engaged, and wherein on both sides of the drive gear arc guides are provided which hold the toothed belt in engagement with the rack so that a first Section absorbs the load and only a short, defined second section of the toothed belt is out of engagement with the toothing. If only relatively small forces occur, this drive is very precise.
  • the known arrangements relate exclusively to the conversion of a rotary movement into a linear movement.
  • a motor screw is known, with the aid of which a rotational movement from a toothed disc to an externally toothed drum is to be transmitted reduced.
  • guide rollers are provided which limit the engagement bend of the toothed belt to a certain smaller angle than in the normal case in order to avoid unpleasant disturbances due to slight interference of the tooth pitches of the toothed belt.
  • the innovation is based on the task of creating a device for forwarding and, if necessary, converting a rotary movement, with which tools, tool tables, handling devices or robots can be moved without vibration and slip with a low mass moment of inertia, with high acceleration and deceleration values and with great setting accuracy .
  • Timing belts in particular plastic timing belts, can now be manufactured with great accuracy with regard to tooth shape and tooth pitch, are sufficiently flexible, wear-resistant and low-noise and have a favorable efficiency. They are also manufactured in an endless version and can be provided with a steel wire core or with glass fiber reinforcement.
  • FIG. 1 shows a device for transmitting a rotary movement between two gearwheels that differ greatly in size
  • FIG. 2 shows a device for transmitting a rotary movement between two gearwheels of essentially the same size
  • Fig. 3 shows a device according to Fig. 1 or 2, in which the deflecting rollers have different diameters.
  • the device shown in FIG. 1 essentially consists of a drive pinion 10, an endless transmission element, in particular a toothed belt 11, two deflection rollers 12 and 13 and an output gear 14, which in the present case has a considerably larger pitch circle than the drive gear.
  • the drive pinion 10 is driven by a motor, not shown, or in another manner known per se.
  • the toothed belt 11 is pressed over the deflection rollers 12 and 13 into the toothing of the drive pinion 10 and the driven gear 14. This results in the engagement areas A and B. Outside of these engagement areas A and B of the drive pinion 10 and the output gear 14, the toothed belt 11 rests with its rear side the circumferential surfaces of the deflection rollers 12 and 13 in the area C in a non-positive manner.
  • the area in which the toothed belt 11 is neither positively nor positively guided can - as the drawing shows easily - be made practically zero by appropriate measures, so that free expansion of the toothed belt 11 is excluded.
  • Drive pinion 10 and driven pinion 14 engage from two opposite sides in the toothing of the loop formed by the toothed belt 11 in such a way that they abut the deflection rollers 12 and 13 with the interposition of the toothed belt 11. This has to mean that where the engagement areas A and B of the drive pinion 10 and the output gear 14 end, the toothed belt 11 inevitably rests on the deflection rollers 12 and 13 and thus the frictional support of the toothed belt 11 on the deflection rollers 12 and 13 starts.
  • a single output gear 14 can be driven by a plurality of drive pinions 10 or drive gears 15 via the device described above. This has the advantage that even if one drive fails in an emergency, the other drives can still make an adjustment movement (albeit with reduced force).
  • the toothed belt 11 used is preferably those which have profiles with a small flank angle. As a result, the buoyancy forces which want the toothed belt 11 to rise from the tooth profile are kept very low.
  • a tooth profile with a semicircular tooth cross-section has proven to be very cheap.
  • the device described above is particularly well suited for numerical control, enables high acceleration due to the low masses with shock compensation, allows a component design in which several drive or output devices can be arranged on a single gear and has a high efficiency and long lifetime.
  • Transmission elements toothed on both sides, both toothed belts 11 and toothed chains, can also be used.
  • the deflection rollers 12, 13 then also have a toothing on their circumference, into which the toothed belt 11 (with the toothing of its rear side) or into which a toothed chain engages.
  • deflection rollers 12 'and 13 with different diameters or pitch circle diameters are provided, which then also result in correspondingly different speeds of the deflection rollers 12' and 13, respectively.

Abstract

Le dispositif ci-décrit permet une grande précision de positionnement, une résistance considérable à l'usure et une efficacité de fonctionnement, associées à des caractéristiques d'engagement grandement améliorées. Ce résultat est obtenu grâce à l'utilisation d'une courroie dentée sans fin (11) qui passe autour de deux rouleaux de renvoi (12, 13). De cette manière la région d'engagement des dents des pignons qui s'engrènent mutuellement (10, 14, 15) s'en trouve considérablement élargie.
