Gear Accuracy Grades – Standards & Classification

Gearaccuracy mamakisi anotsanangura thekushivirira uye mazinga chaiwoyegiya yakavakirwa pamaitiro epasi rose (ISO, AGMA, DIN, JIS). Aya mamakisi anovimbisa meshing chaiyo, kudzora ruzha, uye kugona mumagiya masisitimu

1. Gear Accuracy Standards

ISO 1328 (Yakanyanya Kuzivikanwa Chiyero)

Inotsanangura magiredhi gumi nemaviri echokwadi (kubva pakakwirira kusvika pazasi chaipo):

Magiredhi 0 kusvika 4 (Ultra-chaizvo, semuenzaniso, aerospace, metrology)

Magiredhi 5 kusvika 6 (Yakanyanya kunyatsojeka, semuenzaniso, kutapurirana kwemotokari)

Magiredhi 7 kusvika 8 (General industrial machinery)

Grade 9 kusvika 12 (Low precision, semuenzaniso, midziyo yekurima)

AGMA 2000 & AGMA 2015 (US Standard)

Inoshandisa Q-nhamba (Quality Grades):

Q3 kusvika Q15 (Yepamusoro Q = kunyatsojeka)

Q7-Q9: Yakajairika kumagiya emotokari

Q10-Q12: High-chaiyo aerospace/mauto

DIN 3961/3962 (ChiGerman Standard)

Zvakafanana neISO asi nekuwedzera kushivirira zvikamu.

JIS B 1702 (Japan Standard)

Anoshandisa Grade 0 kusvika 8 (Giredhi 0 = kunyatsojeka).

2. Key Gear Accuracy Parameters

Kururama mamakisi kunotsanangurwa nekuyera:

1.Tooth Profile Error (Kutsauka kubva kune yakanaka involute curve)

2.Pitch Kukanganisa (Kusiyana kwepakati pemazino)

3.Runout (Eccentricity yegiya kutenderera)

4.Lead Kukanganisa (Kutsauka mukugadzirisa mazino)

5.Surface Pedzisa (Kukasharara kunokanganisa ruzha & kupfeka)

3. Typical Applications by Accuracy Grade

ISO Grade	AGMA Q-Giredhi	Typical Applications
Grade 1-3	Q13-Q15	Ultra-chaiyo (Optics, aerospace, metrology)
Grade 4-5	Q10-Q12	Yepamusoro-yekupedzisira mota, marobhoti, turbines
Grade 6-7	Q7-Q9	General muchina, maindasitiri gearboxes
Grade 8-9	Q5-Q6	Zvekurima, zvekuvaka
Grade 10-12	Q3-Q4	Zvikumbiro zvinodhura, zvisingakoshi
