Learnt with calculating:
If the ground supports of two kinds of methods are the material of consistent steel plate place mat, the weight of weight or load, wheel and rolling bar
Material and external diameter are also identical, when the gradient, windage is disregarded, analyze their frictional resistance:
1st, frictional resistance of the dolly with wheel in carrying heavy goods:
If frictional resistance F during dolly carrying heavy goods:F by wheel and ground rolling frictional resistance F1And in wheel
Friction F caused by portion's bearing2Resistance is combined, i.e.,:
In formula:
The weight of N --- weight or load;
The rolling friction factor of μ --- bearing and heart axle;
D --- mandrel diameters;
The diameter of D --- wheel or roller;
F --- wheel or roller and the coefficient of rolling friction on ground.
2nd, with the frictional resistance during method carrying heavy goods of rolling bar
If frictional resistance during rolling bar carrying heavy goods is F:
Because the rail material that is contacted above and below roller is consistent, i.e. the coefficient of rolling friction f1=f2 of roller and track, above-mentioned public affairs
Formula is rewritable to be:
From above-mentioned several formula, resistance when transporting weight using roller method will be less than car wheel.
In addition, being transferred to mandrel and bearing after the wheel body stress of wheel type rotating disk, mandrel and bearing transmit the force to branch again
Frame, therefore mandrel and bearing bear huge load, easily cause damage, and the roller of the roller type rotating disk of the present invention is straight
Connect and stress is transferred to track, the mandrel of roller is not subject to Main Load, damage is not easily caused.
