Mzigo sawa wa nguvu wa beari P ni nini?

The equivalent dynamic load P is a hypothetical constant radial load that would give the same bearing life as the actual combined radial and axial loads. It is calculated as P = X·Fr + Y·Fa, where X and Y are load factors depending on the bearing type and load ratio.

Mambo ya X na Y ni nini?

X is the radial load factor and Y is the axial load factor. They depend on the bearing type and the ratio Fa/Fr relative to the e-value. When Fa/Fr ≤ e, the axial load has negligible effect (X=1, Y=0). When Fa/Fr > e, both X and Y apply.

Thamani ya e katika mahesabu ya beari ni nini?

Thamani ya e ni uwiano wa kizingiti mahususi kwa kila aina ya beari. Inabainisha kama mzigo wa mhimili (axial) unaathiri kwa kiasi kikubwa maisha ya beari. Wakati Fa/Fr inazidi e, kipengele cha Y lazima kitumike kuzingatia mchango wa mzigo wa mhimili.

Ninashughunikaje mzigo wa radial peke yake?

For pure radial load (Fa = 0), the equivalent load simplifies to P = Fr. No axial factor applies, and you can use the radial load directly in the L10 life calculation.

Naweza kutumia hii kwa mzigo sawa wa tuli P0?

Kikokotoo hiki kinahesabu mzigo sawa wa nguvu P kwa mahesabu ya maisha ya beari. Kwa mzigo sawa wa tuli P0, fomula ni sawa lakini inatumia vipengele tofauti vya X0 na Y0. Tumia kikokotoo cha Kipengele cha Usalama wa Tuli wa Beari kwa tathmini ya P0.

Mzigo Sawa wa Nguvu

Mzigo sawa wa nguvu wa bearing unachanganya nguvu za radial na axial katika thamani moja:

Sharti ni: kama F_a/F_r ≤ e, basi P = F_r. If F_a/F_r > e, basi P = X·F_r + Y·F_a.

Vipengele vya X, Y na e kulingana na Aina ya Bearing

Bearing Type	e	X (Fa/Fr ≤ e)	X (Fa/Fr > e)	Y (Fa/Fr > e)
Beari ya mpira wa mfereji wa kina (DGBB)	0.19	1	0.56	2.30
Mzunguko wa pembe 15°	0.38	1	0.44	1.47
Mzunguko wa pembe 25°	0.68	1	0.41	0.87
Mzunguko wa pembe 40°	1.14	1	0.35	0.57

ℹ️ Note: Thamani zilizo hapo juu ni thamani za kawaida zilizorahisishwa. Thamani halisi za X, Y, na e zinategemea mfululizo mahususi wa beari na uwiano C₀/F_a. Rejelea katalogi za mtengenezaji kwa thamani sahihi.

Mfano wa Vitendo

Mfano — Beari ya Mpira wa Mfereji wa Kina 6208

Given: F_r = 8 kN, F_a = 3 kN

F_a/F_r = 3/8 = 0.375 > e = 0.19 → axial load is significant

P = 0.56 × 8 + 2.30 × 3 = 4.48 + 6.90 = 11.38 kN
