Today, we are going to discuss the "Load calculation for bearings and bearings (driven by chain and belt)Here is a note about "The
Load on bearings and bearings
I will summarize in this article,This calculation is used to determine how much load is applied to a bearing when a shaft is held in place by a bearing and turned by a motor in a conveyor drive, for example.
In fact, this formula is not so necessary due to the large allowable load of bearings, but it is a formula for grasping the need for more compact design and cost reduction.
Calculation formulas for bearing and bearing loads
The formula for calculating the load is as follows
This calculation is based on the formula in NTN's catalog. (See the following table.(Calculation reference: NTN Rolling Bearing General Catalog CAT. NO.2202-VII/J,A-23)Also, the reference book uses a formula to calculate the bearing load from the transmission capacity (kW), but in my case, I often calculate it from the actual drive torque to be turned, so I have changed the formula to obtain the transmission capacity (kW) from the torque and apply it to the calculation formula.
requirement
Please refer to the above figure for the necessary conditions for the calculation.
Load value on bearing to be sought
(1) Calculate the transmitted power from the drive torque (supplementary calculation)
W[kW]=0.1047*N*T1/1000
(2) Load acting on sprocket or pulley
Kt[N]=((19.1*(10^6*H))/(Dp*Ns))
(3) Load taking into account initial tension (initial)
Kr(F1)[N]=fb*Kt
Radial load on bearing A
FrA[N]=(((a+b)/b)*F1)+((d/(c+d))*F2)
(5) Radial load on bearing B
FrB[N]=-((a/b)*F1)+((c/(c+d))*F2)

We have created this load calculation formula in Excel for your use if you need it.
That's it.
