Embodiment Construction

[0029] It can be seen from the background art that the service life of the current tapered roller bearing is not good.

[0030] In order to prolong the service life of the tapered roller bearing, an embodiment of the present invention provides a grease collecting device and a tapered roller bearing, by fixing the grease collecting device on one of the bearing outer ring and the spacer ring, and the There is a gap between the grease collecting device and the other of the bearing outer ring and the intermediate ring, and the grease collecting device is provided with an oil outlet hole penetrating through the housing of the grease collecting device. Because the grease collecting device is installed between the bearing outer ring and the intermediate ring, by storing the grease at the position of the intermediate ring in the hollow oil storage chamber, when the bearing is running at high speed, the grease in the grease collecting device can pass through the oil outlet hole Slowly ...

Abstract

The embodiment of the invention provides a tapered roller bearing and a grease collecting device. The whole grease collecting device is of an annular structure and is provided with a hollow oil storage cavity, and the grease collecting device is suitable for being arranged between a bearing outer ring and a middle spacer ring and fixed to one of the bearing outer ring and the middle spacer ring. Agap is formed between the grease collecting device and the other one of the bearing outer ring and the middle spacer ring, and an oil outlet hole is formed in the grease collecting device and penetrates through a shell of the grease collecting device. The grease collecting device provided by the embodiment of the invention can reduce the internal temperature rise of the bearing and prolong the service life of the bearing.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of machinery, in particular to a tapered roller bearing and a grease collecting device. Background technique [0002] Tapered roller bearings are mainly used in scenarios that need to bear combined axial and radial loads at the same time, including bearing inner rings, bearing outer rings, cages and rollers, where the bearing inner rings, rollers and cages form a whole, The bearing inner ring assembly is formed, that is, the cage clamps the bearing inner ring, thereby confining the rollers between the bearing inner ring and the cage. In order to control the axial clearance of the bearing, taking the scheme of the inner ring of the double row bearing as an example, the axial clearance is usually adjusted by setting an intermediate ring between the two inner rings of the bearing to maintain the consistency of the bearing size . [0003] When the bearing is running at high speed, due...
