The invention relates to a transmission component provided with a lubrication induction module; wherein, a contact resistance way is applied by the lubrication induction module for judging whether three components, namely a rolling component, a first component and a second component are completely covered by lubrication oil slick for mutual isolation so as to insulate; if the lubrication slick cannot completely isolate the three components, a message can be transmitted by a warning component of the induction module so that a user can know that the transmission component needs to be added withlubricant; thus the lubrication of the transmission component can be ensured being maintained at the sufficient state so as to avoid the situation of high temperature caused by the rising of frictionresistance due to high speed running when the transmission component does not have sufficient lubrication.
