Gearho nepahala ha limaraka li hlalosamamello le maemo a nepahetsengea likere tse ipapisitseng le maemo a machabeng (ISO, AGMA, DIN, JIS). Limaraka tsena li netefatsa meshing e nepahetseng, taolo ea lerata, le katleho lits'ebetsong tsa lisebelisoa
1. Litekanyetso tsa ho nepahala ha Gear
ISO 1328 (Maemo a Tloaelehileng Haholo)
E hlalosa lintlha tse 12 tsa ho nepahala (ho tloha holimo ho isa ho tse tlase):
Kereiti ea 0 ho isa ho ea 4 (Ho nepahala haholo, mohlala, sepakapaka, metrology)
Kereiti ea 5 ho isa ho ea 6 (Bonepa bo phahameng, mohlala, phetisetso ea likoloi)
Kereiti ea 7 ho isa ho ea 8 (Mechini e akaretsang ea indasteri)
Kereiti ea 9 ho isa ho ea 12 (Ho nepahala ho tlase, mohlala, lisebelisoa tsa temo)
AGMA 2000 & AGMA 2015 (US Standard)
E sebelisa linomoro tsa Q (Mephato ea Boleng):
Q3 ho Q15 (Q e phahameng = ho nepahala ho betere)
Q7-Q9: E tloaelehileng bakeng sa likere tsa likoloi
Q10-Q12: Sebaka se phahameng sa sefofane / sesole
DIN 3961/3962 (Tlhahiso ea Sejeremane)
E ts'oana le ISO empa ka mekhahlelo e meng ea mamello.
JIS B 1702 (Maemo a Majapane)
E sebedisa Kereiti ya 0 ho isa ho ya 8 (Kereiti ya 0 = nepahalo e phahameng ka ho fetisisa).
2. Mekhahlelo ea ho nepahala ha Gear Key
Limaraka tsa ho nepahala li khethoa ka ho metha:
Phoso ea Boemo ba 1.Tooth (Ho kheloha ho tloha mokhoeng o loketseng oa involute)
2.Phoso ea Pitch (Ho fapana ha sebaka sa meno)
3.Runout (Eccentricity of gear rotation)
Phoso ea 4.Lead (Ho kheloha ho lokisoa ha meno)
5.Surface Finish (Bothata bo ama lerata le ho apara)
3. Likopo tse Tloaelehileng ka Kereiti ea ho nepahala
| Sehlopha sa ISO | AGMA Q-Mophato | Lisebelisoa tse Tloaelehileng |
| Sehlopha sa 1-3 | Q13-Q15 | Ho nepahala haholo (Optics, aerospace, metrology) |
| Sehlopha sa 4-5 | Q10-Q12 | Likoloi tsa maemo a holimo, liroboto, li-turbine |
| Sehlopha sa 6-7 | Q7-Q9 | Mechini e akaretsang, li-gearbox tsa indasteri |
| Sehlopha sa 8-9 | Q5-Q6 | Temo, thepa ea kaho |
| Sehlopha sa 10-12 | Q3-Q4 | Lisebelisoa tse theko e tlase, tse seng bohlokoa |
4. Ho Lekanyetsoa ho Nepaha ha Lichelete Joang?
Lisebelisoa tsa Gear (mohlala, Gleason GMS Series, Klingelnberg P-series)
CMM (Mochini o lekanyang oa Coordinate)
Ho hlahlojoa ha Laser & Li-Projectors
Sistimi ea Tlhahlobo ea Gear ea Gleason
GMS 450/650: Bakeng sa lisebelisoa tse phahameng tsa spiral bevel & hypoid
300GMS: Bakeng sa tlhahlobo ea lisebelisoa tsa cylindrical
5. Ho Khetha Mophato o Nepahetseng oa ho nepahala
Kereiti e Phahameng = Ts'ebetso e bonolo, lerata le fokolang, bophelo bo bolelele (empa bo theko e boima haholo).
Kereiti e Tlase = E na le litšenyehelo empa e kanna ea ba le mathata a ho sisinyeha le ho apara.
Khetho ea Mohlala:
Phetiso ea likoloi: ISO 6-7 (AGMA Q8-Q9)
Li-Helicopter Gears: ISO 4-5 (AGMA Q11-Q12)
Conveyor Systems: ISO 8-9
