Den foreliggende opfindelse angår et gear, som kan omsætte en retlinet bevægelse til en roterende bevægelse eller omvendt og af den i krav l's indledning angivne art.The present invention relates to a gear which can convert a rectilinear movement into a rotating movement or vice versa and of the kind specified in the preamble of claim 1.
5 Fra US patentskrift nr. 4315751 kendes en drivmekanisme, hvor et eller flere hjul i deres cylinderformede perifere overflade har et rundtgående spor til optagelse af en kuglekæde, idet det rundtgående spor i afstande, der svarer til afstanden mellem kuglerne på kæden, har udvidelser til 10 optagelse af kuglerne. Ved træk i kæden vil hjulet dreje om en akse, der står vinkelret på den retning, hvori kæden trækkes. Omvendt vil en drejning af hjulet medføre, at kuglekæden bevæges.U.S. Pat. No. 4,315,751 discloses a drive mechanism in which one or more wheels in their cylindrical peripheral surface have a circumferential groove for receiving a ball chain, the circumferential groove having distances corresponding to the distance between the balls on the chain having extensions for 10 recording of the spheres. When pulling on the chain, the wheel will rotate about an axis perpendicular to the direction in which the chain is pulled. Conversely, turning the wheel will cause the ball chain to move.
15 Ved at udforme gearet som anvist i krav 1 opnår man, at hjulet ved træk i kæden drejer om en akse, der er parallel med den retning, hvori kæden trækkes.By designing the gear unit as indicated in claim 1, it is achieved that the wheel when pulled in the chain rotates about an axis which is parallel to the direction in which the chain is pulled.
Ved den i krav 2 anviste udformning er kuglekædegearet 20 udbygget med et snekkegear.In the design shown in claim 2, the ball chain gear 20 is extended with a worm gear.
Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, hvor 25 fig. 1 viser hoveddelene i et gear ifølge opfindelsen indbyrdes adskilt og i perspektiv, fig. 2 samme, men samlet og med gearhuset delvis gennemskåret, 30 fig. 3 det samlede gear, fig. 4 hoveddelene i en anden udførelsesform for et gear ifølge opfindelsen indbyrdes adskilt og i perspek-35 tiv, og -2-The invention will be explained in more detail below in connection with the drawing, in which fig. 1 shows the main parts of a gear according to the invention mutually separated and in perspective, fig. 2 the same, but assembled and with the gear housing partially cut through, 30 fig. 3 shows the assembled gear, FIG. 4 shows the main parts in another embodiment of a gear according to the invention mutually separated and in perspective, and -2-

fig. 5 det i fig. 4 viste gear samlet og med gearhuset delvis gennemskåret.fig. 5 that in fig. 4 shows gears assembled and with the gear housing partially cut through.
På tegningen er vist en kuglekæde 1, der er en snor, wire 5 eller lignende langstrakt og bøjeligt organ, hvorpå der er støbt eller på anden måde monteret kuglelignende komponenter. Afstanden mellem to på hinanden følgende kugler er konstant langs hele kuglekæden.The drawing shows a ball chain 1, which is a cord, wire 5 or similar elongate and flexible member, on which ball-like components are cast or otherwise mounted. The distance between two consecutive balls is constant along the entire ball chain.
10 På tegningen er også vist et skrueformet kuglekædetandhjul 2, som er et cylinderformet legeme, i hvis cylinderflade der findes en fortanding, der passer til kuglekæden 1. Tænderne er i aksialretningen skrueformede med en stigning, der er et multiplum af afstanden mellem to nabokugler på 15 kæden 1.The drawing also shows a helical ball sprocket 2, which is a cylindrical body, in the cylindrical surface of which there is a toothing which fits the ball chain 1. The teeth are helical in the axial direction with a pitch which is a multiple of the distance between two adjacent balls on The chain 1.
Endelig viser tegningen et gearhus 3, hvori det skrueformede kuglekædetandhjul lejres. Huset har yderligere til formål at styre kuglekæden. Herfor er huset udformet med 20 et gennemgående spor, der har form som en halvcylinder passende til kuglekæden 1. Sporet er placeret pralletl med hjulets 2 akse og i en afstand fra denne som giver et korrekt indgreb af kuglekæden 1 både i tandhjulet 2 og i det halvcylinderformede spor.Finally, the drawing shows a gear housing 3 in which the helical ball sprocket is mounted. The housing further aims to control the ball chain. For this purpose, the housing is formed with a continuous groove which has the shape of a half-cylinder suitable for the ball chain 1. The groove is located parallel to the axis 2 of the wheel 2 and at a distance therefrom which gives a correct engagement of the ball chain 1 both in the gear wheel 2 and in the semi-cylindrical grooves.

Ved træk i kuglekæden 1 i pilens retning (fig. 2) vil kuglerne en efter en paserer den passage, som dannes af husets 3 halvcylinderformede spor og to på hinanden følgende tænder på hjulet 2. På grund af tændernes skråstilling 30 vil hjulet 2 derved blive drejet i forhold til huset 3.By pulling the ball chain 1 in the direction of the arrow (Fig. 2), the balls will one by one pass the passage formed by the semi-cylindrical grooves of the housing 3 and two successive teeth on the wheel 2. Due to the inclination of the teeth 30, the wheel 2 will thereby become rotated relative to the housing 3.
Udvekslingen i gearet kan varieres med stigningen og/eller med antallet af tænder på hjulet. Ved passende valg af stigning vil gearet endvidere være selvlåsende, således at 35 drejning af hjulet ikke kan medføre træk i kæden.The gear ratio in the gear can be varied with the pitch and / or with the number of teeth on the wheel. Furthermore, with the appropriate choice of pitch, the gear will be self-locking, so that rotation of the wheel can not cause tension in the chain.

Ved den i fig. 4 og 5 viste udførel sesform er hjulet 2' dobbeltskåret, idet der foruden den tidligere nævnte for-tanding for kuglekæden 1 også er udformet sædvanlige snekketænder til samvirke med et i huset 3' drejeligt lejret 5 snekkehjul 4.In the case shown in FIG. 4 and 5, the wheel 2 'is double-cut, in addition to the previously mentioned toothing for the ball chain 1, usual worm teeth are also formed for co-operation with a worm wheel 4 rotatably mounted in the housing 3'.
