Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a sliding bearing. Background Art

[0002] Bearings are a crucial component in modern mechanical equipment. Their primary function is to support rotating bodies, reduce friction during movement, and ensure rotational accuracy. They are widely used in numerous fields, including industrial machinery, automobiles, aerospace, and household appliances. Bearings can be broadly categorized into two main types: plain bearings and rolling bearings. Both require lubrication during operation. Plain bearings, however, are directly connected to shafts end-to-end, generating friction and heat during operation. Therefore, lubricating oil also serves a cooling function.

[0003] When lubricating oil is added to the existing sliding bearings through the oil filling hole of the casing, the drive shaft needs to be rotated continuously for multiple times to form an oil film of the lubricating oil. It is easy for the oil film to fail to completely cover the gap between the bearing and the shaft, causing friction between the drive shaft and the bearing during operation, resulting in wear of the drive shaft.

[0012] As a further description of the above technical solution, the oil filling groove has multiple groups of oil filling holes opened in the axial direction.

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0027] like Figure 1-Figure 3 As shown, in one embodiment, a sliding bearing includes: a bearing body 1 , and the bearing body 1 includes a contact portion 2 and a fixing portion 3 .

[0028] Among them, fixing holes 31 are vertically opened on the end face of the fixing part 3, and these fixing holes 31 are used to install and fix the sliding bearing body 1, ensuring that the sliding bearing can be firmly connected to other mechanical parts and operate stably during operation; in order to facilitate disassembly, a top screw hole 32 is specially provided on one side of the fixing hole 31, so that when the bearing needs to be replaced or repaired, the sliding bearing body 1 can be easily disassembled by the top screw, reducing the complexity of the operation.

[0029] Furthermore, an oil filling groove 21 is opened on the side of the contact part 2, and multiple groups of oil filling holes 22 are opened in the oil filling groove 21 for injecting lubricating oil into the bearing during installation and maintenance to reduce friction and improve lubrication effect, thereby extending the service life of the bearing.

[0030] Specifically, the oil filling groove 21 is opened along the circumference of the side wall of the contact part 2, and the overall layout is annular. The oil filling groove 21 consists of a redundant part 211 and an oil filling part 212. The width of the redundant part 211 is 1-1.2 times the width of the oil filling part 212. The redundant part 211 fits the contour inside the unit casing to ensure the stability of installation and operation; the oil filling groove 21 has multiple groups of oil filling holes 22 opened in the axial direction, and 2-4 groups of oil filling holes 22 are opened at equal angles in the circumference to ensure that the lubricating oil can be evenly and fully injected, avoiding excessive friction or excessive temperature due to insufficient lubrication, thereby improving the operating efficiency and durability of the bearing.

[0031] Please continue reading Figure 1-Figure 3 In this embodiment, the contact portion 2 is provided with a first temperature measuring port 23. This port is located above the oil filling groove 21, close to the contact surface, and can directly reflect changes in friction and lubrication conditions. The first temperature measuring port 23 can detect the temperature inside the sliding bearing in real time using a temperature measuring device such as a sensor or thermocouple. This temperature data provides timely feedback on the bearing's operating status.

[0032] Furthermore, the fixed part 3 is provided with a second temperature measuring port 33, which is opened on one side of the bottom of the fixed part 3 as a backup temperature measuring port. It is suitable as a comparison measurement point to provide redundant temperature monitoring. When the first temperature measuring port 23 fails or cannot provide valid data, it can be switched to the second temperature measuring port 33 in time for temperature monitoring to ensure that the temperature monitoring of the bearing is not affected.

[0033] Working principle: When the lubricating oil is added to the bearing through the oil filling hole 22 of the casing, it will enter the gap between the bearing and the shaft through different bearing oil filling holes 22. Therefore, there is no need to rotate the drive shaft to form a complete oil film of the lubricating oil. At the same time, it more completely covers the gap between the bearing and the drive shaft, thereby improving the lubrication effect of the bearing.

[0034] Through the above technical solution, the present application can completely maintain the existence of the oil film when the unit is running, so that the bearings can maintain a good lubrication state when running under high load, reduce wear and heat accumulation, ensure the smooth operation and long-term stability of the mechanical equipment, and thus improve the operating efficiency of the unit.

[0035] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
