Abstract

podstata riešenia spočívá v tom, že převodovka je tvořená hnacím ozubeným kolesom uloženým na noenoa ramene a v záběre s excentrickým hnaným ozubeným kolesom, ktoré sú uložené výsuvné v plášti. Hnané ozubené koleso je ukončené utahovacím kíúčom.the essence of the solution is that the gearbox is formed by a drive gear stored on the noenoa shoulder and in the shots with eccentric driven gear, which are retractable in the housing. The driven gear is terminated by a tightening key.

Description

CS 267 316 B1 1EN 267 316 B1 1

Vynález sa týká převodovky pře uíahovacie jednotky*BACKGROUND OF THE INVENTION The present invention relates to a gearbox for a transfer unit

Doteraz známe uíahovacie jednotky pozoetávajú z vlastného pneumatického notóra,ktorý je ukončený uíahovacím klúčom. Pre vačšie krútiace momenty sú známe uíahova-cie jednotky, na ktorých výstupe sú uložená bežne známe převodovky posostávajúce zhnacieho a hnaného ozubeného kolesa. Pre zvláší velké krútiace momenty by tieto pře-vodovky zvačšovali rozměry, najma priemer uíahovacích jednotiek, ktoré by tak boliíažko ovládatelné v obmedzenom přieetore uíahovanie nepoužitelné.So far known tightening units consist of their own pneumatic notor, which is finished with a tightening key. For greater torques, the gripping units are known, on the output of which are conventionally known gearboxes seated on a gear and driven gear. For particularly large torques, these gearboxes would increase the dimensions, notably the diameter of the tightening units, which would thus be difficult to control in a limited overrunning fit.

VyfiSie uvedené nedostatky odstraňuje a technický problém rieéi převodovka, naj-ma pře uíahovacie jednotky, podlá vynálezu, ktorej podstata spočívá v tom, že je tvo-řená nosným ramenou, v ktorého dolnej časti je otočné a posuvné uložené hnacie ozu-bené koleso v zábere s excentrickým hnaným ozubeným kolesou. Medzi čelom hnaciehoozubeného kolesa a hnaného ozubeného kolesa je uložená gulka. Hnané ozubené kolesoje otočné a posuvné uložené v puzdre pevne uloženou v plášti. Převodovkou sa docieli zvláší vysokých krútiacich momentov. Uíahovacie jednot-ka podlá vynálezu je použitelná i v íažéie přístupných miestach, čo rozšiřuje jejpoužitelnosí.According to the above mentioned drawbacks, the technical problem is solved by the transmission, in particular by the coupling unit, according to the invention, which consists in the fact that it is formed by a support arm in which the drive ring is rotatably and displaceably mounted in the lower part. with eccentric driven gear. There is a bullet between the face of the driving gear and the driven gear. Driven gear wheels rotatable and slidable housed in a housing fixed in the housing. The gearbox achieves particularly high torques. The attachment unit according to the invention can also be used in open areas, which extends its applicability.

Na výkrese je znázorněné příkladné rieženie převodovky pre uíahovacie jednotkykde na obr. 1 je táto nakreslená v osovou raze, pričom lává čaeí je v zasunutéj po-lohe a pravá časí je vo vysunutéj polohe. Převodovka pre uíahovacie jednotky pozostáva zo základnej došky 11, ktorá jeuehytená maticou 2 na uíahovacej jednotke 10 a zaistená poistnou podložkou 8. Naštvorhrannom klúči 14 pevne uchytenom na odpruženom hriadeli 15 uíahovacej jednotky10 je uložené hnacie ozubené koleso 12. ktorého dolná časí je otočné a posuvné ulo-žená v dolnom puzdre ? nalisovanom v nosnom ramene 1,· Horná časí nosného ramena 1.je pevne priskrutkovaná na základnej doske 11. Hnacie ozubené koleso 12 je v záberes excentrickým hnaným ozubeným kolesou 2« Hnané ozubené koleso 2 je otočné a posuv-né uložené v puzdre 2, pevne uloženou v plášti 6, ktorého horné čelo je priskrutko-vané na základnej doske 11. Medzi dolným čelom hnacieho ozubeného kolesa 12 a hna-ného ozubeného kolesa 2 je uložená gulka 13. Na dolnom konci hnaného ozubeného kole-sa 2 je pevne prostredníctvom kolíka £ uložený uíahovaci klúč 2·In the drawing, an exemplary gear transmission for the pulling unit shown in FIG. 1 is drawn in an axial stroke, wherein the flap is in the retracted position and the right portion is in the extended position. The gearbox for the tightening units consists of a basic dowel 11 which is secured by a nut 2 on the tightening unit 10 and secured by a lock washer 8. A drive gear 12 is mounted on the square key 14 fixed on the spring shaft 15 of the tightening unit 10, the lower gear of which is rotatable and sliding in the lower case? The upper gear portion of the support arm 1 is fixedly screwed onto the base plate 11. The drive gear 12 is engaged with the eccentric driven gear 2. The driven gear 2 is rotatable and slidably mounted in the housing 2, rigidly A bullet 13 is disposed between the lower face of the driving gear 12 and the driven gear 2 and is fixed to the lower end of the driven gear 12 by means of a pin 8. saved taper key 2 ·

Punkcia převodovky je nasledovná:Transmission puncture is as follows:

Po spustení uíahovacej jednotky 10 sa roztoči jej štvorhranný klúč 14 spoločne s kto-rým sa roztočí aj hnacie ozubené koleso 12. Pri nasadzovaní uíahovacieho kldča 2 nahlavu uíahovanej skrutky ak nastane odpor sa čiastočne zatlačí hnané ozubené koleso2 a cez gulku 13 aj hnacie ozubené koleso 12. Po správnou nasunutí uíahovacieho klúča5 na hlavu uíahovanej skrutky (na obr. nezakreslené) pokračuje uíahovanie až po nas-tavený krútiaci moment.Upon actuation of the tightening unit 10, its square key 14 is rotated together with which the drive gear 12 also rotates. When the tightening knob 2 is pushed in, the driven gear 2 is partially pressed through the ball 13 and the drive gear 12 is pushed. After correct insertion of the tightening key 5 on the head of the tightened screw (not shown in the figure), the tightening continues until the torque is set.

Odpruženie celej prevodovej sústavy zabraňuje poškodeniu uíahovacieho klúča 2»připadne uíahovacej jednotky pri nenasunutí uíahovacieho klúča 2 na hlavu uíahovanejskrutky, alebo matice a súčasne slúži na lahšie oddelenie uíahovacieho klúča 2 od uía-hovanej hlavy skrutky po ukončeni uíahovanie.The suspension of the entire transmission system prevents damage of the tightening key 2 to the tightening unit when the tightening key 2 is not pushed onto the head of the screw or nut, and at the same time serves to easily separate the tightening key 2 from the fastened head of the screw after finishing the tightening.
