Razvoj nove generacije polževega zobniškega prenosa za kuhinjske aparate

Herman, Jan (author), Vukašinović, Nikola (mentor)

Delo obravnavana že obstoječo polžasto zobniško dvojico, ki se vgrajuje v gospodinjske aparate v serijski proizvodnji. Polžnik obstoječe dvojice ima posebno geometrijo ozobljenja, ki se je ne da analitično ovrednotiti. V nalogi je najprej predstavljena obstoječa polževa dvojica. Sledi teoretični pregled polžastih dvojic, polimernih materialov ter polimernih zobnikov s povzetkom priporočila za njihovo ovrednotenje VDI 2736. Teoretični pregled se zaključi s predstavitvijo programskih paketov KISSsoft in Ansys, ki smo ju v analizi polžaste dvojice uporabili. V volumnu obstoječe zobniške dvojice se najprej definira nova standardna zobniška dvojica, ki je obstoječi čim bolj podobna. Za standardno dvojico se izvede analitičen preračun po priporočilu VDI 2736, analiza v programu KISSsoft in numerični preračun po metodi končnih elementov. Temu sledi ovrednotenje obstoječega serijskega gonila po metodi končnih elementov. V zaključku naloge so predstavljene ugotovitve analize ter predlogi za izboljšave obstoječe zobniške dvojice.

• Title: Development of a new generation of worm gear transimition for kitchen appliances

Abstract

The thesis derives from the existing serial produced worm gear that is used in the household kitchen appliances. The existing worm wheel has a special tooth geometry, which cannot be analytically evaluated. First, we explain the existing serial worm gear in detail. After, we present the theoretical background of worm gears, basics of polymer materials, polymer gears and a guideline for polymer gear evaluation VDI 2736. Then we present KISSsoft and Ansys, which are the software we used in the worm gear analysis. The goal is to create a 3D model of the standard worm gear, which will be as much alike to the existing serial one. The newly generated standard worm gear is evaluated in KISSsoft, analytically with VDI 2736 and also with finite element method. Then, the existing serial worm gear is evaluated with finite element method. Lastly, we present and compare the results from different gear evaluation methods. Based on the results we suggest the improvements of the existing gear.
