Solid cage and reinforced solid tapered roller bearing

Abstract

The invention provides a solid cage and a reinforced solid tapered roller bearing. The bearing comprises an inner ring, an outer ring, a tapered roller and a solid cage, wherein a plurality of roller mounting holes are milled by a numerical control milling machine along the circumference of the solid cage, the mounting holes are in the shape of a radial straight hole having an angle same as a contact angle of the roller, solid parts of the solid cage comprises two side rings and a plurality of lintels between the rings, the side surface of each lintel is respectively provided with two symmetrical lock points, each lock point is a square neck formed by two square bumps, an arc surface cooperating with the roller is milled inwardly in the square neck, the tapered roller guides rotation of the solid cage in virtue of the lock points on the solid cage, the external surface of the inner ring is provided with a U-shaped neck cooperating with the tapered roller, and the tapered roller is mounted through an outer mounting hole in the solid cage and is assembled with the inner ring to form an inner ring assembly. The bearing provided by the invention has the advantages great bearing capability, a long service life, smooth operation, low friction, good lubrication performance, good vibration resistance, etc.

Description

technical field [0001] The invention relates to the technical field of bearings, and mainly relates to a structural type of a reinforced solid tapered roller bearing. Background technique [0002] Currently, tapered roller bearings such as figure 1 As shown: it is composed of outer ring 11, inner ring 12, roller 13, and cage 14; the raceways and rollers of the inner and outer rings are tapered, and the extension lines of all tapered surfaces converge at a certain point on the bearing axis , The cage adopts a stamped steel structure, which has the advantages of light weight and can bear two-way loads. However, due to the influence of structural design, machining accuracy and bearing assembly process, this product generally has disadvantages such as low load-carrying capacity, short life, high noise at high speed, and poor lubrication performance. Contents of the invention [0003] The object of the present invention is to provide a solid cage and a reinforced solid tapere...
