Description

Technical Field

[0001] The utility model belongs to the field of bearing manufacturing, in particular to a tapered roller bearing group with an inner sleeve plane and a washer. Background Art

[0002] When modifying equipment equipped with tapered roller bearings, the shaft size is lengthened, resulting in the need to lengthen the mating surface between the inner ring of the bearing and the shaft. The height size of the inner ring needs to be adjusted, but the bearing's load-bearing capacity already meets the needs of the equipment and no adjustment is required. In this case, the bearing size needs to be adjusted and a new product needs to be designed.

[0003] Since the load-bearing capacity of the tapered roller bearing has met the needs of the equipment, manufacturing new bearings would be time-consuming, labor-intensive and a waste of resources. Utility Model Content

[0004] The present application provides a tapered roller bearing set with a flat inner sleeve and a washer, so as to solve the technical problem that the existing tapered roller bearings are not compatible with the dimensions of improved equipment.

[0005] In order to solve the above technical problems, the embodiments of the present application disclose the following technical solutions: The present application provides a tapered roller bearing group with an inner sleeve plane and a washer, comprising: a pair of tapered roller bearings and a washer, the washer is fitted between the adjacent end faces of a pair of tapered roller bearing inner rings; the sum of the height of the washer and the height of the pair of tapered roller bearing inner rings is equal to the height of the shaft mating surface of the equipment on which the tapered roller bearing group is installed; when the equipment on which the pair of tapered roller bearings are installed is modified, the size of the shaft is lengthened, and the sum of the height sizes of the shaft washer and the washer matches the size of the modified shaft, so that the mating surfaces of the two match.

[0006] Preferably, the gasket is evenly provided with oil storage holes which penetrate the gasket radially; there are at least two oil storage holes; and the center of the gasket and the center of the shaft are on the same axis.

[0007] Preferably, the adjacent end faces of a pair of tapered roller bearing inner rings are fitted with the end faces of the washers; the height dimension of the washers depends on the height of the shaft ring and shaft mating surface required by the equipment for installing the bearings, and the height dimension of the washers is obtained by subtracting the size of the shaft ring from the height dimension of the mating surface.

[0008] Preferably, the diameter of the inner circle of the washer is larger than the inner circle diameter of the inner ring of the tapered roller bearing; the diameter of the inner circle of the washer cannot be smaller than the diameter of the shaft ring, otherwise the washer cannot be strung onto the shaft of the equipment.

[0009] Preferably, the outer diameter of the washer is smaller than the maximum diameter of the rib where the inner ring of the tapered roller bearing is located; in order to prevent oil from flowing back into the bearing and affecting the service life of the bearing.

[0010] Preferably, the tapered roller bearing is a single-row tapered roller bearing or a double-row tapered roller bearing.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] When the equipment equipped with the tapered roller bearing group is modified, the size of the shaft is lengthened, and the height size of the inner ring of the tapered roller bearing and the washer matches the size of the lengthened shaft. There is no need to redesign and produce new bearings, and the axial displacement of the internal components can be limited to the maximum extent, thereby increasing the service life of the tapered roller bearing and other bearings on a shaft. In addition, the gasket processing is relatively convenient and accurate, and different equipment can be processed separately, which greatly ensures the quality and quantity of the products processed by the equipment, saves time and labor, saves a lot of tooling, and reduces processing costs. When the shaft is shortened, the gasket can also be taken out and re-ground to make it shorter, so as to achieve the goal of not replacing the bearing. It should be understood that the above general description and the detailed description below are only exemplary and explanatory and cannot limit the present application.

[0016] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0017] See Figure 1 Embodiment 1: A tapered roller bearing set with a flat inner sleeve and a washer, comprising: a pair of tapered roller bearings 1 and a washer 2, wherein the washer 2 is fitted between adjacent end faces of a pair of tapered roller bearing inner rings 3; the sum of the height of the washer 2 and the height of the pair of tapered roller bearing inner rings 3 is equal to the height of the shaft mating surface of the equipment on which the tapered roller bearing set is installed; when the equipment on which the pair of tapered roller bearings are installed is modified, the size of the shaft is lengthened, and the sum of the height dimensions of the shaft washer and the washer matches the size of the modified shaft, so that the mating surfaces of the two match.

[0018] Preferably, the gasket 2 is evenly provided with oil storage holes 4 which penetrate radially therethrough; there are at least two oil storage holes 4; the function of the oil storage holes is to store oil and dirt to extend the service life of the bearing; the center of the gasket 2 and the center of the shaft are on the same axis.
