Idelna prestava se nanaša na prestavo, ki igra prenosno vlogo med dvema prestavnima prestavnima prestavkoma, in mrežami z obema prestama, da spremenite smer vrtenja pasivne prestave, zaradi česar je enaka kot gonilna prestava . Njegova funkcija je samo za spremembo krmiljenja in ne more spremeniti razmerja prenosa, imenovan Idler .
The wheels that mainly utilize their inertia in mechanical equipment are collectively referred to as idlers. In a wheel system, if a gear is both the driven wheel of the previous stage of transmission and the driving wheel of the subsequent stage of transmission, then this gear is called an idler gear. The idler gear, also known as the bridge gear, has no effect on the transmission ratio value based on its number of teeth, but it bo vplival na krmiljenje zadnjega kolesa .
