Φ90 H7 / r5

Φ90 H7

Ag = 35µm = 0.035 mm

Ad=0

Dg = D + Ag = 90 + 0.035 = 90.035 mm

Dd = D + Ad = 90 + 0 = 90 mm

Φ90 r5

ag = 66 µm = 0.066 mm

ad = 51 µm = 0.051 mm

dg = d + ag = 90 + 0.066 = 90.066 mm

dd = d + ad = 90 + 0.051 = 90.051 mm

Pg = dg - Dd = 90.066 - 90 = 0.066 mm = 66 µm

Pd = dd – Dg = 90.051 - 90.035 = 0.016 mm = 16 µm

Tn = Pg – Pd = 66 – 16 = 50 µm

Provera:

T = Ag – Ad = 35 – 0 = 35 µm

t = ag – ad = 66 – 51 = 15 µm

Tn = T + t = 35 + 15 = 50 µm

Ag = 47 µm = 0.047 mm

Ad = 12 µm = 0.012 mm

Dg = D + Ag = 90 + 0.047 = 90.047 mm

ag = 0

ad = - 54 µm = - 0.054 mm

dg = d + ag = 90 + 0 = 90 mm

dd = d + ad = 90 + (-0.054) = 89.946 mm

Zg = Dg – dd = 90.047 – 89.946 = 0.101 mm = 101 µm

Zd = Dd – dg = 90.012 – 90 = 0.012 mm = 12 µm

Tn = Zg – Zd = 101 – 12 = 89 µm

Provera:

T = Ag – Ad = 47 – 12 = 35 µm

t = ag – ad = 0 – (-54) = 54 µm

Tn = T + t = 35 + 54 = 89 µm

Zg = Dg – dd = 90.035 – 89.991 = 0.044 mm = 44 µm

Pg = Dd – dg = 90 – 90.013 = - 0.013 mm = - 13 µm

Tn = Zg – Pg = 44 – (-13) = 57 µm

Provera:
