[0002] Tapered roller bearings are a type of separable bearings. Both the inner and outer rings of tapered roller bearings have tapered raceways. There are single-row tapered roller bearings, double-row tapered roller bearings, four-row tapered roller bearings, etc. Tapered roller bearings have the advantages of compact structure, strong load-bearing capacity, and separable inner and outer rings. They are widely used in automobile transmissions, and are also used in rolling mills, mining, metallurgy, plastic machinery and other industries.

[0003] A tapered roller bearing with Chinese patent number CN211039408U relates to the field of bearings and solves the problem of insufficient lubricating oil in existing tapered bearings. The bearing comprises an inner ring and an outer ring, a retaining frame mounted on the inner ring and a roller mounted on the retaining frame. An oil storage ring that contacts the retaining frame is fixedly connected to the inner ring, and an oil storage cavity is arranged on the oil storage ring. The utility model has the effect of continuously providing lubricating oil to the bearing and the roller, reducing friction damage and prolonging the service life of the bearing.

[0004] When multiple tapered roller bodies are installed in the mounting inner groove in the protective frame, the multiple tapered roller bodies have no stress points and are easy to fall off. It is not easy for inexperienced users to conveniently assemble the tapered roller bearing device, which is not conducive to ensuring the installation efficiency of the tapered roller bearing device. Therefore, it is necessary to design a tapered roller bearing device that is easy to install to solve the above problems.

[0005] Therefore, a tapered roller bearing device which is easy to install is proposed. Utility Model Content

[0006] In view of this, the utility model provides a tapered roller bearing device that is easy to install to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0007] The technical solution of the utility model is achieved as follows: a tapered roller bearing device that is easy to install, including an internal ring, the outer end of the internal ring is sleeved with a protective frame, the outer end of the protective frame is provided with a plurality of mounting inner grooves, the plurality of mounting inner grooves are arranged annularly and equidistantly, the inner ends of the mounting inner grooves are clamped with tapered roller bodies, the plurality of tapered roller bodies are arranged annularly and equidistantly, the tapered roller bodies are located between the internal ring and the protective frame, the outer end of the protective frame is sleeved with an external ring, and the inner end of the protective frame is provided with a deformable thin iron ring sheet.

[0008] Further preferably, the deformable thin surface iron ring piece is located between the tapered roller body and the inner ring, and the outer end of the deformable thin surface iron ring piece is fixedly connected with an outer protruding pull tab.

[0009] Further preferably, the outwardly protruding pull tab passes through the inside and outside of the corresponding installation inner groove and extends to the outside of the protective frame.

[0010] Further preferably, a pull ring is provided at one end of the outwardly protruding pull tab away from the inner installation groove, and the pull ring is located outside the protective frame.

[0011] Further preferably, the outer side surface of the deformable thin iron ring sheet is fixedly connected with an outer convex rough surface, and a plurality of lubricating greases are attached to the outer side of the outer convex rough surface.

[0012] Further preferably, the lubricating grease is in contact with the tapered roller body and the inner ring, and mounting inner concave rings are provided at both upper and lower ends of the outer ring.

[0013] Further preferably, the two mounting inner concave rings are vertically symmetrically arranged, and a cross bar is fixedly connected between the left and right inner walls of the mounting inner concave rings.

[0014] Further preferably, an extension pull rope is sleeved on the inner end of the mounting inner concave ring, and the extension pull rope is located on the inner side of the cross bar.

[0015] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0016] 1. In this solution, when multiple tapered roller bodies are installed in the installation inner grooves in the protection frame, the deformable thin-surface iron ring piece can limit the tapered roller body in the protection frame, so that a force point is generated in the inner position, and then the internal ring is vertically inserted into the protection frame, so that the deformable thin-surface iron ring piece is located between the internal ring and the protection frame. At this time, the tapered roller body can be completely limited in the corresponding installation inner groove. At this time, the finger is hooked on the pull ring outside the convex pull piece to pull out the deformable thin-surface iron ring piece. For inexperienced users, it is easy and convenient to assemble the tapered roller bearing device, which is beneficial to ensure the installation efficiency of the tapered roller bearing device.

[0017] Second, at the same time, convex rough surfaces can be set on the left and right sides of the deformable thin iron ring piece, and lubricating grease can be applied to the outside of the convex rough surfaces. When the deformable thin iron ring piece is pulled out as a whole, the lubricating grease can be evenly attached to the tapered roller body, the extension rope, and the inside and outside positions of the internal ring, which can play a role in maintenance. In addition, inner concave rings can be installed at the upper and lower positions of the external ring, and the extension ropes installed in the inner concave rings are symmetrically arranged to form force points, which can facilitate the tapered roller bearing device to be more conveniently installed on the outside of the relevant installation shaft.
