Embodiment Construction

[0009] Such as figure 1 As shown, a deep groove ball bearing that can be added with grease includes an outer ring 1, an inner ring 2, a sealing ring 3, and a plurality of balls 4. The bottom of the inner ring raceway 2a is provided with Extended oil groove 2b, the inner ring 2 is provided with an oil injection hole 2c, the oil inlet end of the oil injection hole 2c is in the inner circle of the inner ring 2, and the oil inlet end of the oil injection hole 2c is sealed with a sealing screw 5, and the oil outlet of the oil injection hole 2c The end communicates with the bottom of the oil tank 2b.

[0010] During oil filling, the sealing screw 5 can be removed, and grease is injected into the oil groove 2b from the oil filling hole 2c. After the oil filling is completed, the sealing screw 5 can be used again to seal the oil inlet end of the oil filling hole 2c.

[0011] The present invention is not limited to the above-mentioned embodiments. On the basis of the technical solutio...

Abstract

The invention relates to the technical field of bearings, and discloses a deep groove ball bearing allowing grease to be added therein. The deep groove ball bearing comprises an outer ring, an inner ring, a sealing ring and a plurality of balls; an oil groove extending in the peripheral direction of an inner ring rollaway nest is formed in the bottom of the inner ring rollaway nest, an oil injecting hole is formed in the inner ring, the oil inlet end of the oil injecting hole is located in an inner circle of the inner ring, the oil inlet end of the oil injecting hole is packaged through a sealing screw, and the oil outlet end of the oil injecting hole is communicated with the bottom of the oil groove. Oil injection can be carried out in time, and the deep groove ball bearing is suitable for use in a heavy load occasion.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a deep groove ball bearing. Background technique [0002] At present, deep groove ball bearings with sealing rings are the most widely used, mainly including outer rings, inner rings, sealing rings, and multiple balls. [0003] However, in actual use, with the high-speed rotation of the balls, the grease on the bearings will leak, which will lead to corrosion of the balls and poor rotation over time. Contents of the invention [0004] The object of the present invention is to provide a deep groove ball bearing that can be added with grease, which can be filled with oil in time and is suitable for use under heavy loads. [0005] The purpose of the present invention is achieved in this way: a deep groove ball bearing that can be added with grease, including an outer ring, an inner ring, a sealing ring, and a plurality of balls, and the bottom of the inner ring raceway is provid...
