High-strength lubrication type planetary gear assembly

The utility model relates to the technical field of gears, in particular to a high-strength lubrication type planetary gear assembly which comprises a main gear and further comprises a plurality of planetary gear mechanisms connected with the periphery of the main gear in a meshed mode. The protection mechanism is arranged on the outer sides of all the planetary gear mechanisms; the planet carrier is fixedly connected with each planetary gear mechanism; the fixing mechanism is arranged on one side of the protection mechanism; through the arrangement of the planetary gear mechanisms and the protection mechanism, the multiple planetary gear mechanisms can be effectively protected through the protection mechanism, on one hand, loss of the outer sides of planetary gears is reduced, on the other hand, the using effect of the planetary gears can be improved through lubricating oil added into the outer protection ring, and meanwhile the service life is prolonged; and the connection stability of the planetary gear ca
