Abstract

Technical Field
[0001] This utility model relates to the field of spherical bearing technology, specifically a high-temperature resistant spherical bearing. Background Technology
[0002] Bearings are essential components in modern machinery, primarily functioning to support rotating parts, reduce friction during movement, and ensure rotational accuracy. There are various types of bearings, including sliding bearings, spherical plain bearings, rolling bearings, needle roller bearings, and deep groove ball bearings. Spherical roller bearings are a type of deep groove ball bearing, characterized by high load capacity, low operating noise, long service life, and excellent sealing performance. They are commonly used in high-temperature operating environments.
[0003] Spherical roller bearings are characterized by the spherical shape of their outer ring's outer diameter surface. They consist of several key components: an inner ring, an outer ring, balls, and a cage. Notably, these bearings feature an oil filling hole on the outer ring, allowing operators to drip lubricating oil into the ball bearing area to reduce ball wear during operation. The lubricating oil also cools the bearing and prevents overheating. However, current commercially available spherical roller bearings still have certain limitations in lubrication: existing lubrication methods cannot quickly and evenly distribute lubricating oil to all critical parts of the bearing, leading to insufficient lubrication in certain areas, thus accelerating wear and reducing service life. Therefore, a high-temperature resistant spherical roller bearing is proposed. Utility Model Content

[0026] Example
[0027] Existing lubrication methods cannot quickly and evenly distribute lubricating oil to all critical parts of the bearing.
[0028] Please see Figures 1-4 This utility model provides a technical solution: a high-temperature resistant spherical bearing, including a main body assembly 101, which includes an outer ring 11, a cage 12, an inner ring 13, and balls 15;
[0029] The ball 15 is rotatably connected to the inside of the cage 12. The inner ring 13 is located inside the outer ring 11. The cage 12 is located between the inner ring 13 and the outer ring 11. The outer ring 11, the inner ring 13, the cage 12 and the ball 15 provide external support and fixation for the bearing. The outer diameter surface of the outer ring 11 is spherical, which allows it to fit into the corresponding concave spherical surface of the bearing housing, playing a self-aligning role and thus adapting to errors during the installation process.
[0030] An oil injection assembly 301 is provided on the outer ring 11. The oil injection assembly 301 includes a sealing ring 31, an oil injection pipe 32, an oil injection chamber 33, an oil injection hole 34, and an oil distribution hole 35.
[0031] The oil filling chamber 33 is located on the front surface of the outer ring 11. Oil filling holes 34 are evenly distributed on the inner rear wall of the oil filling chamber 33. Oil distribution holes 35 are evenly located inside the outer ring 11 and communicate with each of the oil filling holes 34. A sealing ring 31 is fixedly connected to the front surface of the outer ring 11, and its position corresponds to the position of the oil filling chamber 33. An oil filling pipe 32 is fixedly connected to the front surface of the sealing ring 31 and communicates with the oil filling chamber 33. When lubricating the bearing, lubricating oil is injected into the oil filling chamber 33 through the oil filling pipe 32, and then the lubricating oil flows into the corresponding oil filling holes 34. The oil flows into the distribution holes 35 and finally into various positions within the inner groove 16. When the balls 15 roll within the inner groove 16, they can fully contact the lubricating oil. Because the distribution holes 35 are evenly distributed within the inner groove 16, the lubricating oil can lubricate the balls 15 in an efficient and uniform manner. This lubrication method improves the operating efficiency of the bearing and effectively reduces friction and wear between the balls 15 and the inner groove 16, thereby reducing the heat generated by friction, improving the stability and durability of the bearing in high-temperature environments, and enhancing the high-temperature resistance of the bearing.
[0032] In this embodiment, specifically: the inner wall of the outer ring 11 is provided with an inner groove 16, the oil distribution hole 35 is connected to the inner groove 16, the outer wall of the ball 15 is attached to the inner wall of the inner groove 16, the outer wall of the inner ring 13 is provided with an outer groove 14, the outer wall of the ball 15 is attached to the inner wall of the outer groove 14, the inner groove 16 and the outer groove 14 provide a rolling path for the ball 15, when the bearing is running, the ball 15 rolls along the inner groove 16 and the outer groove 14, ensuring the smooth operation of the bearing.
[0033] In this embodiment, specifically: two mounting grooves 36 are symmetrically opened on the outer side wall of the inner ring 13, and blades 37 are symmetrically fixedly connected to the inner side wall of the mounting grooves 36. The blades 37 are symmetrically located in front of and behind the outer ring 11. When the bearing is running, the inner ring 13 rotates at high speed, and the inner ring 13 drives the blades 37. Under the action of the blades 37, the air outside the bearing flows rapidly, which can make the bearing fully contact with the air and enhance the heat dissipation effect of the bearing.
[0034] The working principle or structural principle is as follows: When lubricating the bearing, lubricating oil is injected into the oil filling chamber 33 through the oil filling pipe 32. Then, the lubricating oil flows into the corresponding oil distribution holes 35 through the oil filling holes 34, and finally flows into various positions in the inner groove 16. When the balls 15 roll in the inner groove 16, they can fully contact the lubricating oil. Since the oil distribution holes 35 are evenly distributed in the inner groove 16, the lubricating oil can lubricate the balls 15 in an efficient and uniform manner. When the bearing is running, the inner ring 13 rotates at high speed, and the inner ring 13 drives the blades 37. Under the action of the blades 37, the air outside the bearing flows rapidly, which can make the bearing fully contact with the air and enhance the heat dissipation effect of the bearing.
[0035] In summary, this invention injects lubricating oil into the oil injection chamber 33 through the oil injection pipe 32. Then, the lubricating oil flows into the inner groove 16 through the oil injection hole 34 and the oil distribution hole 35. When the ball 15 rolls in the inner groove 16, it can fully contact the lubricating oil. Since the oil distribution hole 35 is evenly distributed in the inner groove 16, the lubricating oil can lubricate the ball 15 in an efficient and uniform manner. This lubrication method improves the operating efficiency of the bearing and can effectively reduce the friction and wear between the ball 15 and the inner groove 16, thereby reducing the heat generated by friction, improving the stability and durability of the bearing in high-temperature environments, and enhancing the high-temperature resistance of the bearing.
