Speed reducer with oil injection structure

Abstract

The utility model relates to the technical field of speed reducer, specifically is a kind of speed reducer with oil injection structure, including speed reducer body, the transmission case shell top of speed reducer body is equipped with oil injection port, oil injection port inner cavity is inserted with oil inlet pipe, and the one end of oil inlet pipe is fixedly connected with oil sending mechanism;The utility model passes through the oil pipe into the lubricating oil barrel, pull up the telescopic rod on oil cylinder, and the telescopic rod drives piston upwards, and the first movable plug blocks the axle hole of piston, and the second movable plug leaves the bottom port of oil cylinder, so that the lubricating oil in the lubricating oil barrel enters the bottom of oil cylinder under the action of atmospheric pressure, when pushing telescopic rod and piston downwards, the second movable plug blocks the bottom port of oil cylinder, and the first movable plug separates from the axle hole of piston upwards, and lubricating oil enters the top of oil cylinder through the bottom of oil cylinder, solve the problem that the lubricating oil needs to be frequently replaced in the use process of existing speed reducer, and oil injection operation is too cumbersome.
