Abstract
Способ измерения мощности потерь на трение в подшипниках качения, отличающийся тем, что мощность потерь энергии в подшипнике качения определяется как произведение суммы моментов инерции системы вращающихся масс «ротор приводного двигателя, соединительная муфта, движущиеся элементы подшипника качения» на сумму «угловой скорости и половины приращения угловой скорости за период, в течение которого определено угловое ускорение системы вращающихся масс «ротор приводного двигателя, соединительная муфта, движущиеся элементы подшипника качения» с учетом приведенного момента инерции сопротивления качению, на разность углового ускорения системы вращающихся масс «ротор приводного двигателя, соединительная муфта» и углового ускорения системы вращающихся масс «ротор приводного двигателя, соединительная муфта, движущиеся элементы подшипника качения», определенного с учетом приведенного момента инерции сопротивления качению.A method for measuring the power of friction losses in rolling bearings, characterized in that the power of energy losses in a rolling bearing is defined as the product of the sum of the moments of inertia of the system of rotating masses “drive motor rotor, coupling, moving elements of the rolling bearing” by the sum of “angular velocity and half increment angular velocity for the period during which the angular acceleration of the system of rotating masses is determined “rotor of the drive motor, coupling, moving bearing elements to value ”, taking into account the reduced moment of inertia of rolling resistance, on the difference between the angular acceleration of the system of rotating masses“ rotor of the drive motor, coupling ”and the angular acceleration of the system of rotating masses“ rotor of the drive motor, coupling, moving elements of the rolling bearing ”, determined taking into account the reduced moment inertia of rolling resistance.
