Description

Technical Field

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

[0002] With the continuous development of the automotive industry, especially with advancements in powertrains and transmission systems, automotive balance bearings, as key components, shoulder the heavy responsibility of reducing friction between balance shafts and other components, improving power transmission efficiency, and extending service life. While traditional automotive balance bearings can provide basic support, they are susceptible to friction, wear, insufficient lubrication, and leakage over long-term use, impacting bearing performance and service life, leading to increased maintenance costs.

[0003] There are several common problems with automotive balance bearings on the market:

[0004] Poor wear resistance: The wear-resistant layer of traditional bearings is easily worn, resulting in increased friction, which in turn affects the operating efficiency of the vehicle.

[0005] Uneven distribution of lubricating oil: The existing bearing structure fails to effectively ensure that the lubricating oil is evenly distributed within the bearing, which affects the lubrication effect and accelerates component wear.

[0006] Poor sealing performance: Many traditional bearings have sealing design defects, which can easily lead to lubricating oil leakage, causing oil seal failure and shortening the service life of the bearing.

[0007] In order to solve the above problems, the utility model provides a new type of balance bearing design for automobiles, which has better wear resistance, lubrication effect and sealing performance, thereby effectively extending the service life of the bearing and reducing maintenance costs.

[0016] 2. Uniform lubricant distribution: The wear-resistant layer of this utility model is equipped with a mesh oil groove. This oil groove design ensures uniform distribution of lubricant, reduces friction and wear caused by insufficient lubrication, and further improves the operating stability and efficiency of the bearing. The connection between the oil chamber and the oil filling hole allows easy injection of lubricant into the oil groove, ensuring that the lubricant can flow effectively during operation.

[0017] 3. Excellent sealing: In the design of the present invention, a first sealing ring is provided between the limit ring and the bearing sleeve, and a second sealing ring is provided between the bearing cover and the bearing sleeve, which effectively prevents the leakage of lubricating oil and ensures that the internal lubricating oil can be kept in the working area of the bearing for a long time, thereby improving the sealing effect and service life of the bearing.

[0018] 4. Strengthen positioning and fixing functions: The design provides several positioning pins on both sides of the inner sleeve, which are connected to the bearing sleeve through the positioning pin holes to ensure the fixed position of the inner sleeve in the bearing sleeve, avoid displacement in high temperature and high pressure working environment, and further improve the stability and safety of the bearing.

[0019] 5.
