Description

Technical Field

[0001] The utility model belongs to the technical field of bearing lubrication, and particularly relates to a rolling bearing with plastic oil. Background Art

[0002] Lubrication is an essential link between friction pairs in the normal operation of mechanical equipment and in the process of material manufacturing and processing. With the rapid development of industry, various forms of lubrication have emerged, from the initial oil lubrication to the later self-lubrication and other slow developments. In large rolling bearings, copper or PEEK cages are often used.

[0003] At present, a Chinese utility model with announcement number: CN210565789U discloses a bearing retainer, including a support body on a retainer body, a pocket formed between two adjacent support bodies, the side walls of the pockets are arranged in an arc shape in cooperation with the rolling bodies, oil storage grooves are provided on the side walls on both sides of the pockets, the oil storage grooves are arranged along the height direction of the retainer body, ventilation holes are provided on the side walls of the support body, the length direction of the ventilation holes is arranged along the radial direction of the retainer, and a plurality of ventilation holes are provided along the height direction of the support body. The utility model has the advantages of good heat dissipation, good lubrication effect, and improved service life.

[0004] However, the above device still has certain defects. For example, most of the current cylindrical roller bearing cages are integrated. When the cylindrical roller is worn or damaged, it is difficult for the operator to remove the damaged cylindrical roller from the cage. After the overall disassembly, the gap between the cylindrical roller bearings is easily increased, and the bearing cylinder and the outer ring of the bearing are in contact and friction for a long time, which is very easy to cause the bearing roller to wear, thereby affecting the service life of the bearing. Based on the above problems, we provide a rolling bearing with plastic oil. Utility Model Content

[0005] The utility model aims to provide a rolling bearing with plastic oil, which has the advantages of taking into account the role of retaining steel balls and lubricating the steel balls, which can effectively increase the service life of the steel balls and greatly improve the applicability of retaining particles.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a rolling bearing with plastic oil, including a bearing outer ring and a bearing inner ring, wherein steel balls and retaining particles are respectively slidably connected between the bearing outer ring and the bearing inner ring, and the steel balls and retaining particles are alternately installed between the bearing outer ring and the bearing inner ring in sequence, and the two sides of the retaining particles are slidably connected to the surface of the steel balls, and a cavity is opened inside the retaining particles, and the retaining particles are filled with a plastic oil inner core through the cavity opened inside.

[0007] By adopting the above technical scheme, the rolling steel balls are positioned by retaining particles and the spacing between multiple steel balls is maintained, thereby facilitating the removal of the steel balls from between the outer ring and the inner ring of the bearing. At the same time, a plastic oil core is installed inside the retaining particle, so that when the steel balls roll, the oil film can lubricate the surface of the steel balls, reduce the friction of the rolling steel balls, and reduce wear. In this way, the function of retaining the steel balls is taken into account, and at the same time, the function of lubricating the steel balls is also achieved, which can effectively increase the service life of the steel balls and greatly improve the applicability of the retaining particles.

[0008] The utility model is further configured as follows: a sliding groove slidably connected to the steel ball is provided between the outer ring of the bearing and the inner ring of the bearing.

[0009] The above technical solution is used to position the rolling of the steel ball, thereby improving the stability of the sliding contact between the steel ball and the retaining particle.

[0010] The utility model is further configured as follows: arc-shaped surfaces are provided on both sides of the outer side of the retaining particle close to the outer ring of the bearing and the inner ring of the bearing.

[0011] The above technical solution facilitates installation and disassembly between the retaining particles and the outer ring and the inner ring of the bearing, and reduces the friction force of the retaining particles sliding between the outer ring and the inner ring of the bearing.

[0012] The utility model is further configured as follows: the top and bottom of the steel ball and the retaining particle are both provided with a dust cover plate clamped between the outer ring of the bearing and the inner ring of the bearing.

[0013] By adopting the above technical solution, the steel balls and retaining particles are protected to prevent dust from entering the interior, increasing the rolling wear of the steel balls and thus affecting the service life of the bearings.

[0014] The utility model is further configured as follows: the retaining particle is injection molded by an injection molding machine and a mold, and the shape of the retaining particle is trapezoidal, with a larger end close to the outer ring of the bearing and a smaller end close to the inner ring of the bearing.

[0015] The above technical solution facilitates installation and disassembly between the retaining ball and the bearing outer ring and the bearing inner ring, thereby facilitating replacement of damaged steel balls.

[0016] The utility model is further configured as follows: the height of the retaining particles is not less than two centimeters, and the thickness between the retaining particles and the bearing outer ring and the bearing inner ring is not less than one centimeter.

[0017] By adopting the above technical solution, the retaining particles can fully separate the steel balls, thereby reducing the wear of the steel balls and facilitating disassembly and replacement.

[0018] In summary, the utility model has the following beneficial effects:

[0019] The rolling steel balls are positioned by retaining particles and the spacing between multiple steel balls is maintained, thereby facilitating the removal of the steel balls from between the outer ring and the inner ring of the bearing. At the same time, a plastic oil core is installed inside the retaining particle, so that when the steel balls roll, the oil film can lubricate the surface of the steel balls, reduce the friction of the rolling steel balls, and reduce wear. This not only takes into account the function of retaining the steel balls, but also has the function of lubricating the steel balls, which can effectively increase the service life of the steel balls and greatly improve the applicability of the retaining particles.
