The invention relates to the technical field of transmission equipment, and discloses a pumping unit speed reducer bearing lubricating device capable of adjusting the oil supply amount. A shell is included, driving shafts are movably mounted on the two sides of an inner cavity of the shell, a transmission shaft is movably mounted in the middle of the inner cavity of the shell, and bearings are movably mounted at two ends of the transmission shaft. An oil passing groove is formed in the middle of the shell, and lubricating holes are formed in the two sides of the oil passing groove. By arranging an oil circulating mechanism, when the amount of lubricating oil in a speed reducer is normal, under the action of an oil amount control mechanism, a movable block moves upwards, the oil passing groove is sealed in a staggered mode, the upper end of an oil suction groove is in butt joint with the outer end of a connecting hole, accordingly, under the cooperation of an air cooling heat dissipation mechanism, the oil acc
