The heating of bearings is usually determined by the following factors: friction, bearing load, speed, lubrication, and environmental temperature. However, accurately calculating the heat generation of bearings is a complex process that requires considering multiple factors and formulas. The following is a simplified method to estimate the heat generation of bearings:
1. Calculate the power generated by rolling friction of the rolling element based on the bearing load. The power generated by rolling friction can be calculated by the following formula:
P=F × V
Among them, P is the frictional power in watts, F is the load on the bearing in newtons, and v is the rolling speed of the bearing in meters per second.
2. Calculate the heat generated by rolling friction based on the rotational speed of the bearing. The heat can be calculated by the following formula:
Q=P × Δ T
Where Q is the heat generated by rolling friction in joules, Δ T is the running time per unit time (in seconds).
3. Consider other factors such as lubrication and heat dissipation. The lubrication state will have an impact on the heat of the bearing, while the heat dissipation situation will affect the heat dissipation. These factors usually require estimation or actual testing based on specific application situations.
Please note that this is only a simplified estimation method and cannot provide very accurate results. If more heat calculation is needed, it is recommended to consult Shanghai Anding Yitai Technical Engineer 136-2180-8094.
