Description

Technical Field

[0001] The utility model relates to a single-row cylindrical roller bearing. Background Art

[0002] Single row cylindrical roller bearing is an important type of bearing, suitable for rigid support, short shaft support, shafts that cause axial displacement due to thermal elongation, and machine accessories that require separate bearings for installation and disassembly. This makes it widely used in various mechanical equipment.

[0003] Although the single-row cylindrical roller bearings currently in use are suitable for high-speed rotation, at extremely high speeds, their internal friction and heat accumulation may cause the temperature of the bearing to rise, thereby accelerating the oxidation and failure of the lubricating oil and reducing the life of the bearing. Utility Model Content

[0004] The utility model aims to provide a single-row cylindrical roller bearing to solve the above technical problems.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A single-row cylindrical roller bearing comprises a bearing outer ring, a bearing inner ring and a bearing retainer. The bearing inner ring is fixedly connected inside the bearing outer ring, and the bearing retainer is fixedly connected between the bearing outer ring and the bearing inner ring.

[0007] Based on the above technical solution, the bearing retainer includes an outer bracket, a rolling body slot, a rolling body shaft slot, a rolling body shaft, a rolling body, and an auxiliary structure. A rolling body slot is opened at the center of the outer bracket, and the rolling body shaft slot is opened at the top and bottom center of the inner side of the outer bracket. The rolling body shaft is connected to the rolling body shaft slot axis, and the rolling body is slidably connected to the outside of the center of the rolling body shaft. The four auxiliary structures are respectively opened on both sides of the two rolling body shaft slots.

[0008] Based on the above technical solution, the auxiliary structure includes a pulley slot, a pulley shaft slot, a pulley shaft, and an auxiliary pulley. Two pulley shaft slots are respectively provided at the top and bottom centers of the inner side of the pulley slot. The pulley shaft is connected to the two pulley shaft slot shafts, and the auxiliary pulley is slidably connected to the outside of the pulley shaft.

[0009] Compared with the prior art, the utility model has the following advantages: the utility model improves the existing single-row cylindrical roller bearing design structure, reduces the internal friction coefficient by using an auxiliary structure, and thus increases the service life of the single-row cylindrical roller bearing.

DETAILED DESCRIPTION

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1-3 As shown, a single-row cylindrical roller bearing comprises a bearing outer ring 1, a bearing inner ring 2, and a bearing retainer 3. The bearing inner ring 2 is fixedly connected inside the bearing outer ring 1, and the bearing retainer 3 is fixedly connected between the bearing outer ring and the bearing inner ring 2.

[0016] The bearing retainer 3 includes an outer bracket 4, a rolling body slot 5, a rolling body shaft slot 6, a rolling body shaft 7, a rolling body 8, and an auxiliary structure 9. A rolling body slot 5 is opened at the center of the outer bracket 4, and the rolling body shaft slot 6 is opened at the center of the top and bottom of the inner side of the outer bracket 4. The rolling body shaft 7 is axially connected to the rolling body shaft slot 6, and the rolling body 8 is slidably connected to the outside of the center of the rolling body shaft 7. The four auxiliary structures 9 are respectively opened on both sides of the two rolling body shaft slots 6.

[0017] The auxiliary structure 9 includes a pulley slot 10, a pulley shaft slot 11, a pulley shaft 12, and an auxiliary pulley 13. Two pulley shaft slots 11 are respectively provided at the top and bottom center of the inner side of the pulley slot 10. The pulley shaft 12 is axially connected to the two pulley shaft slots 11, and the auxiliary pulley 13 is slidably connected to the outside of the pulley shaft 12.

[0018] The working principle of the utility model is as follows: when the internal rolling body rotates, the top and bottom of the rolling body shaft are respectively linked with four auxiliary pulleys, and the friction coefficient is reduced by utilizing the auxiliary pulleys and lubricating oil, thereby reducing the heat generated when the single-row cylindrical roller bearing is working, thereby increasing the service life of the single-row cylindrical roller bearing.

[0019] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
