A wear-resistant, lightweight bearing housing assembly

Abstract

This invention provides a wear-resistant, lightweight bearing housing assembly, including a base with a support fixedly mounted on the top. The support has multiple wear-resistant components on its inner wall and a bushing inside. This invention fundamentally reduces the coefficient of friction by utilizing the rolling friction of balls instead of traditional sliding friction, significantly reducing wear during operation. Furthermore, lubricating oil injected through the oil injection hole forms a uniform and stable fluid lubrication film on the ball surface, effectively isolating direct metal-to-metal contact and simultaneously dissipating heat, cooling, and removing wear debris. The fitting structure of the first and second grooves ensures the sealing of the lubrication system, preventing lubricant leakage and maintaining continuous and effective lubrication. The synergistic effect of the mechanical rolling structure and fluid lubrication significantly improves the wear resistance of the bearing housing, significantly reduces operating noise and temperature rise, and extends the service life of the equipment.

Description

Technical Field

[0001] This utility model mainly relates to the field of bearing housing technology, specifically a wear-resistant and lightweight bearing housing assembly. Background Technology

[0002] A bearing housing is a component used to fix and support a bearing. It provides the bearing with a mounting position and load-bearing capacity, ensuring stable and accurate operation during operation. Bearing housings typically have good strength and rigidity, capable of withstanding various loads transmitted by the bearing.

[0003] In existing technologies, traditional bearing housing assemblies typically employ sliding friction, which results in a high coefficient of friction. This leads to severe wear between components during operation and fails to achieve the synergistic effect of mechanical rolling structure and fluid lubrication. Consequently, it generates high noise and temperature rise during operation, affecting equipment operating efficiency and causing severe equipment wear. Utility Model Content

[0004] This utility model mainly provides a wear-resistant and lightweight bearing housing assembly to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A wear-resistant lightweight bearing housing assembly includes a base, a support seat fixedly mounted on the top of the base, a plurality of wear-resistant components provided on the inner wall of the support seat, a bushing provided inside the support seat, and a plurality of first grooves provided on the outer side of the bushing.

[0006] Preferably, the wear-resistant component includes a second groove and balls. The second groove is provided on the inner wall of the support base, and multiple balls roll and rub inside the second groove. The balls are distributed circumferentially inside the second groove with the center point of the support base as a reference.

[0007] Preferably, the second groove has the same depth as the first groove, and the bottom of the ball rolls against the inner wall of the first groove.

[0008] Preferably, the top of the support base is connected to a plurality of oil injection holes, and the number of oil injection holes is the same as the number of second grooves, and the oil injection holes are connected to the second grooves.

[0009] Preferably, the top surface of the base is provided with a first weight-reducing hole, and both sides of the support are provided with a second weight-reducing hole.

[0010] Preferably, the base has fixing holes on both sides of its top, and the fixing holes are used to fix it to an external device by bolts.

[0011] Preferably, a sealing plug is provided inside the oil injection hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By utilizing the rolling friction of balls to replace traditional sliding friction, the coefficient of friction is fundamentally reduced, significantly decreasing wear during operation. Furthermore, the lubricating oil injected through the oil injection hole forms a uniform and stable fluid lubrication film on the ball surface, effectively isolating direct metal-to-metal contact while simultaneously dissipating heat, cooling, and removing wear debris. The fitting structure of the first and second grooves ensures the sealing of the lubrication system, preventing lubricant leakage and maintaining continuous and effective lubrication. The synergistic effect of the mechanical rolling structure and fluid lubrication significantly improves the wear resistance of the bearing housing, significantly reduces operating noise and temperature rise, and extends the service life of the equipment.

[0013] 2. By opening the first and second weight-reduction holes, the weight of the device is further reduced without affecting the structural strength.

[0017] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0018] Please refer to the appendix carefully. Figure 1-4A wear-resistant lightweight bearing housing assembly includes a base 1, a support 2 fixedly mounted on the top of the base 1, and multiple wear-resistant components 3 on the inner wall of the support 2. Each wear-resistant component 3 includes a second groove 301 and balls 302. The second groove 301 is formed on the inner wall of the support 2, and multiple balls 302 are disposed inside the second groove 301. The balls 302 operate through rolling friction, which significantly reduces wear between components compared to traditional sliding friction, thereby extending the service life of the entire assembly. The balls 302 are circumferentially distributed within the second groove 301 with the center point of the support 2 as a reference, resulting in more uniform force distribution and further improving the stability and reliability of the assembly. Furthermore, a bushing 4 is provided inside the support 2, and multiple first grooves 5 are provided on the outer side of the bushing 4. The first grooves 5 and the second grooves 301 cooperate with each other at the same depth, allowing the bottom of the balls 302 to engage with the first grooves. Rolling friction is performed on the inner bottom wall of component 5, thereby forming an efficient rolling contact surface between the two components, further reducing friction and wear. The top of the support base 2 is connected to multiple oil injection holes 6, and the oil injection holes 6 are equipped with sealing plugs 10. When not in use, the oil injection holes 6 are sealed to prevent dust and impurities from entering. At the same time, lubricating oil can be easily injected when needed. The number of oil injection holes 6 is the same as the number of second grooves 301, and the oil injection holes 6 are connected to the second grooves 301 to facilitate the entry of lubricating oil into the second grooves 301 to lubricate the ball bearings 302. The top surface of the base 1 is provided with a first weight reduction hole 7, and the support base 2 is provided with second weight reduction holes 8 on both sides. The first weight reduction hole 7 and the second weight reduction hole 8 help to further reduce the weight of the entire device. The top sides of the base 1 are provided with fixing holes 9, and the fixing holes 9 are fixed to external equipment by bolts to ensure the stability of the components during operation. It should be noted that both the base 1 and the support 2 are made of 42CrMo4 material, achieving lightweight objects, and have undergone heat treatment and tempering, giving the device excellent comprehensive mechanical properties.

[0019] The specific operation method of this utility model is as follows: During use, the bushing 4 fixes the bearing and replaces sliding friction with rolling friction of the balls 302, reducing wear. Then, the sealing plug 10 is removed, and lubricating oil is injected into the top of the oil injection hole 6. The lubricating oil then flows along the oil injection hole 6 into the second groove 301 arranged around the balls 302, fully wetting the balls 302 to form a continuous oil film, which plays a role in heat dissipation, cleaning and corrosion prevention. The first groove 5 fits into the second groove 301 to prevent lubricating oil from leaking from the mating surface. By combining the rolling characteristics of the balls 302 with the fluid lubrication of the lubricating oil film, the dual effect of mechanical structure and lubrication medium is achieved, which significantly improves the overall wear resistance and service life.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
