IiHypoid vs Spiral Bevel Gears — Ukungasebenzi, Ingxolo, kunye nokusebenza kakuhle

Ndihlalutya ukusebenza kwegiya ngokuhlola indlela imigca ephakathi ebeka ngayo umphezulu wepitch kwindawo enemilinganiselo emithathu. Uyilo olubonakalayo lwee-shaft axes lugqiba ukuba amazinyo egiya aqengqeleka kakuhle okanye atyibilika na.

Iikhowuni zePitch ezidibanayo kwiBevel Gears

Iigiya ze-spiral bevel zisebenza kwimigca ephakathi yeshaft edibanayo. Ndicinga ngemiphezulu yazo yepitch njengee-cones ezimbini eziqinileyo eziqengqelekayo kunye ngaphandle kokutyibilika. Zombini ii-pitch cones zidibana kwindawo enye ekwabelwana ngayo. Ndibala ezi shapes zepitch ezi-conical ndisebenzisa iifomyula zejometri ezisisiseko:

●Ifomula yoMlinganiselo weGear: $i = \frac{N_{gear}}{N_{pinion}}$

●Ifomula ye-Angle yePitch Cone yePinion: $\tan(\gamma_p) = \frac{\sin(\Sigma)}{i + \cos(\Sigma)}$ okanye $\gamma_p = \text{atan2}(\sin(\Sigma), i + \cos(\Sigma))$

●Ifomula ye-Angle yeKhowuni yePitch yeGear: $\gamma_g = \Sigma - \gamma_p$

●Inkcazo yeNtlanganiso yeApex: I-apex imele indawo echanekileyo apho iincam ze-pitch cone kunye nemigca ephakathi ye-shaft zidibana khona njengoko iindawo ezimbini ze-conical zijikelezana.

I-Hypoid Gear Kinematics kunye ne-Centerline Offset

Ndenza i-hypoid gear ngokususa umgca ophakathi we-pinion shaft ukusuka kwi-crown gear axis. Lo mgama we-offset uphula i-intersecting cone geometry. Ii-pitch cones azisabelani nge-apex efanayo. Endaweni yoko, i-offset izisa i-sweeping slide ecaleni komkhondo wezinyo. Le space offset yandisa ububanzi be-pinion, nto leyo eqinisa kakhulu amazinyo e-gear.

IiHyperboloids zeNdawo kunye nokuzibandakanya kwamazinyo

Ukubandakanyeka kwegiya le-Hypoid kuxhomekeke kwiindawo ezibizwa ngokuba yi-hyperboloids of revolution. Ngenxa yokuba ezi ndawo zidibana kwii-axes ezingadibaniyo, i-meshing yazo ngokwemvelo ibangela isenzo sokutyibilika okuqhubekayo phakathi kwamazinyo egiya adibeneyo. Ndiyila olu nxibelelwano luyinkimbinkimbi lwendawo ndisebenzisa i-kinematics echanekileyo ye-hyperboloid:

●Ukuveliswa Komphezulu: Ii-axes ezijikelezayo ezingahambelaniyo nezingadibaniyo (ezigobileyo) ezijikeleze umgca ophakathi zenza ii-hyperboloids ezimbini zephepha elinye ezisebenza njengeendawo zomphezulu wepitch.

●Umgca Woqhagamshelwano Okhawulezileyo: Ezi ndawo zilawulwa yi-hyperboloid zidibana kwijenereyitha yomgca othe tye ekwabelwana ngayo ngalo lonke ixesha ngexesha lokujikeleza.

●I-Meshing Kinematics: Njengoko umphezulu ujikeleza, lo mgca woqhagamshelwano uqhubeka utshintsha, uvelisa ipateni yoqhagamshelwano lomgca ebonakaliswa yintshukumo ecocekileyo yokuqengqeleka emqaleni kunye nokutyibilika okuqhubekekayo ukuya kwiziphelo zegiya.

Amanqanaba aphantsi engxolo abonisa ukuhanjiswa komthwalo okusebenzayo kunye nokuncipha kokuwohloka koomatshini ngaphakathi kwiibhokisi zegiya.

Umlinganiselo woQhagamshelwano kunye nokuzibandakanya okuLungileyo

Iigiya zeHypoid zigcina umlinganiselo ophezulu woqhagamshelwano kuneegiya zespiral bevel. I-structural axis offset yolula umgca woqhagamshelwano lomphezulu wezinyo, ivumela amazinyo amaninzi ukuba abelane ngomthwalo wokusebenza kancinci kancinci. Olu qhagamshelwano oluqhubekayo lunciphisa imithwalo yokukhwaza xa amazinyo egiya ngalinye engena kwi-mesh. Ndibona ukwehla okubonakalayo kwimveliso ye-acoustic ngexesha lovavanyo lokusebenza. Ndilinganisa ukwehla kwenqanaba lengxolo ye-5 dB xa nditshintsha ukusuka kwiigiya zespiral bevel ukuya kwiigiya zehypoid. Iigiya zespiral bevel eziqhelekileyo zivelisa malunga ne-50 dB, ngelixa iigiya zehypoid zisebenza kwi-45 dB ezolileyo phantsi kweemeko zokusebenza ezifanayo.
