Abstract

MENJAČ BRZINA NA BUŠILICAMA I GLODALICAMA, je novo konstruktivno rešenje prenosa snage sa motora na radno vreteno mašine, koje omogućuje vrlo veliki izbor broja obrtaja za bušenje ili glodanje svih materijala od drveta do najtvrdjih čelika, veliku pouzdanost u radu, lako i jeftino održavanje, jeftinu izradu i dr. Konstrukcija menjača se sastoji u tome što se više kajišnika (A, B, C, D) raznih veličina slažu u jednake sklopove i odgovarajuće veličine spajaju remenima (1), a ekscentričnom ručicom (7) vrši zatezanje remena (1) i time prenošenje sile okretanja sa motora na radno vreteno (3). Promenom mesta pojedinih kajišnika i njihovim medjusobnim spajanjem remenima dobija se veliki broj kombinacija za odredjivanje broja obrtaja radnog vretena.GEARBOX ON DRILLS AND MILLING MACHINES, is a new constructive solution for power transmission from the engine to the working spindle of the machine, which allows a very large selection of speeds for drilling or milling all materials from wood to the hardest steels, high reliability, easy and cheap maintenance, cheap making, etc. The construction of the gearbox consists in the fact that several belts (A, B, C, D) of different sizes are arranged in equal assemblies and the corresponding sizes are connected by belts (1), and the eccentric lever (7) tightens the belt (1) and thus transmits force. turning from the motor to the working spindle (3). By changing the location of individual belts and their interconnection with belts, a large number of combinations are obtained for determining the number of revolutions of the working spindle.
