The invention relates to an oil storage type anti-falling safety device, which mainly comprises an outer casing, an inner casing, a gear shaft, a centrifugal speed adjusting part, an end cover and a top cover, wherein the outer casing is a reducing type casing and is integrally cast and formed, the outer end surface of the large end part of the outer casing is connected with the end cover through a flange structure, the outer end surface of the small end part of the outer casing is connected with the top cover, and the inner casing is coaxially arranged in the outer casing. The oil storage type anti-falling safety device is characterized in that a first rolling bearing is arranged between the back support section of the gear shaft and the end cover, a second rolling bearing is arranged between the front support section of the gear shaft and the end cover, and at least one oil groove is formed in the inner surface of the first rolling bearing. The oil storage type anti-falling safety device has the advantages that the oil grooves are formed in the corresponding rolling bearing, are used for containing semi-fluid lubricating grease, and are communicated with an oil filling passage on the end cover, so the subsequent maintenance and oil filling are realized, and the abnormal noise of running caused by failure of oil filling and poor lubricating after oil lacking is avoided; the long-time normal running of the anti-falling safety device is guaranteed.
