Tapered roller type reinforced bearing

Abstract

The invention discloses a tapered roller type reinforced bearing which comprises a shaft ring, an end cover, a first tapered outer ring, a second tapered outer ring, a first tapered inner ring, a second tapered inner ring, a first tapered retainer, a second tapered retainer, a first tapered roller and a second tapered roller. L-shaped oil supplementing holes are formed in the top end of one side of the shaft ring and the bottom end of the other side of the shaft ring; one end of the L-shaped oil supplementing hole communicates with the top end and the bottom end of the oil guide loop, the oil guide loop is formed in the center of the inner circumference of the shaft ring, a sealing sleeve and a threaded hole plug are embedded in the other end of the L-shaped oil supplementing hole, and the sealing sleeve is connected to one end of the threaded hole plug in a sleeving mode; the bearing is high in structural strength, the radial load and the axial load of the bearing are increased, the working requirement of a high-strength scene is met, the application range is wide, an oil supplementing structure is additionally arranged, supplementing of lubricating oil is facilitated, time and labor are saved, the maintenance cost of the bearing is reduced, the sealing performance is good, the lubricating oil is not prone to leakage, resource waste is reduced, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of tapered roller bearings, in particular to a tapered roller reinforced bearing. Background technique [0002] Tapered roller bearings refer to radial thrust rolling bearings whose rolling elements are tapered rollers. Structure type. [0003] However, the common tapered roller bearings on the market are not equipped with an oil replenishment structure, so it is difficult to replenish lubricating oil, labor-intensive and time-consuming, increasing the maintenance cost of the bearing, and the sealing is poor, and the lubricating oil is easy to leak, resulting in Waste of resources, pollute the environment, and endanger the health of personnel. In addition, the structure is simple, the strength is low, the radial load and axial load are small, and it is difficult to meet the work requirements of high-intensity scenes, and the scope of application is limited.
