Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a high-load radial bearing assembly. Background Technology

[0002] As a key component in mechanical transmission systems, radial bearings are widely used in various types of equipment. Their main function is to support rotating parts and bear radial loads.

[0003] However, in high-load applications such as heavy machinery, engineering vehicles, and large structural connections, traditional radial bearings face challenges. High loads not only place extremely high demands on the material and structural strength of the bearing itself, but also affect the stability of the connection between the bearing and external equipment.

[0004] To ensure reliable operation under high loads, bearings require continuous and clean lubrication and effective prevention of external contaminants. In existing technologies, bearing installation, sealing structures, and lubrication systems are often designed separately and simply combined. When faced with severe vibrations and potential deformations caused by high loads, such non-integrated assemblies may experience sealing failures, lubricant leaks, and contamination, leading to accelerated bearing wear and ultimately premature failure, which affects the safety and service life of the entire equipment.

[0005] Therefore, this utility model proposes a high-load radial bearing assembly to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of insufficient structural strength, poor connection stability, and low reliability and inconvenient maintenance caused by the separation of lubrication and sealing structures in the existing high-load radial bearing assemblies, this utility model aims to provide a high-load radial bearing assembly with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a high-load radial bearing assembly, including: a connecting wall and a bearing housing fixedly connected to the top of the connecting wall, as well as steel balls, a lubrication cavity, an oil injection hole and a sealing ring.

[0008] The bearing housing has an integrally formed arc-shaped outer ring and a concentrically arranged arc-shaped inner wall. The structural design optimizes the overall stress distribution and enhances the structural strength.

[0009] Furthermore, the steel ball is rotatably disposed within the arc-shaped inner wall of the bearing housing and forms a sliding fit with it. The bearing housing has a lubrication cavity for storing lubricating fluid inside, and an oil injection hole communicating with the lubrication cavity is provided on the top of the bearing housing. The sealing ring is fixedly connected to the inner wall of the bearing housing and seals the lubrication cavity on both the front and rear sides, thereby integrating the load-bearing moving structure and the sealing and lubrication structure into one unit.

[0010] Preferably, the high-load radial bearing assembly further includes a base, which is fixedly connected to the bottom of the connecting wall, providing a flat and stable mounting interface for the entire assembly, facilitating reliable connection with external equipment.

[0011] Preferably, the base and the connecting wall are both provided with connecting threads, which are used to engage with the mounting bolts or studs of external equipment, thereby achieving high-strength fastening and locking, effectively resisting vibration and impact under high load, and enhancing the stability of the connection.

[0012] Preferably, the sealing ring is specifically wrapped around the outer surface of the steel ball, and the inner lip forms a tight dynamic sealing fit with the smooth spherical surface of the steel ball, which can effectively prevent the lubricant in the lubrication cavity from leaking out, and can also scrape off the contaminants attached to the surface of the steel ball, preventing them from entering the bearing.

[0013] Preferably, a sealing screw is threaded to the top of the oil injection hole. The sealing screw not only seals the oil injection hole to prevent lubricant from overflowing and impurities from entering, but the threaded connection also makes lubrication maintenance operations quick and convenient.

[0014] Preferably, the high-load radial bearing assembly further includes a second sealing ring, which is fixedly connected inside the oil injection hole and located below the sealing screw. It is used to fill and seal the gap between the sealing screw and the inner wall of the oil injection hole, forming a double guarantee and further improving the sealing reliability of the oil injection port.

[0015] Preferably, the connecting wall and the bearing housing are an integral structure. This seamless integral structure eliminates stress concentration and potential assembly gaps at the connection point, fundamentally improving the rigidity and strength of the structure, and enabling it to better withstand and transmit high loads.

[0016] Preferably, in the structure disclosed in this utility model, the connecting wall, bearing seat, base, steel ball, connecting thread, arc-shaped inner wall and arc-shaped outer ring together constitute the connecting mechanism to realize the connection and movement function under high load, while the sealing ring one, sealing ring two, sealing screw, oil injection hole and lubrication cavity together constitute the sealing mechanism to realize the long-term sealing and lubrication function.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of insufficient structural strength and unstable connection of existing bearings under high load by designing the connecting wall and bearing seat as an integral structure and equipping the bearing seat with an arc-shaped outer ring and a base with connecting threads. It improves the overall rigidity and load-bearing capacity to ensure long-term stable and reliable installation.

[0018] 2. This utility model solves the problems of difficult lubrication and poor sealing leading to increased wear in existing bearings by integrating a lubrication cavity and an oil injection hole inside the bearing housing, and by coordinating a sealing screw, a first sealing ring and a second sealing ring to form a double seal. It can facilitate maintenance, ensure long-term lubrication and reduce friction and wear.

[0019] 3. This utility model solves the problem that traditional rigid connections are difficult to adapt to installation errors and dynamic angle changes by adopting a structure in which the steel ball and the arc-shaped inner wall of the bearing seat rotate together. It achieves reliable load bearing while also having angle self-adaptation and self-aligning functions, thereby improving the overall operating accuracy of the equipment. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0023] Please refer to Figures 1 to 4 This utility model provides a high-load radial bearing assembly, which aims to solve the problems of insufficient structural strength, poor connection stability, and severe wear caused by the lack of an integrated sealing and lubrication structure in existing radial bearings under high load conditions.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the high-load radial bearing assembly includes a connecting wall 1 and a bearing housing 2 fixedly connected to the top of the connecting wall 1; the connecting wall 1 serves as the basic support and connecting platform for the entire high-load radial bearing assembly, while the bearing housing 2 is used to bear loads and realize rotation and lubrication functions; specifically, the connecting wall 1 and the bearing housing 2 are an integral structure, and this integrated design enhances the stability and strength of the structure; The outer wall of the bearing housing 2 is integrally formed into an arc-shaped outer ring 35. The arc-shaped outer ring 35 optimizes stress distribution through a smoothly transitioned arc surface structure, thereby improving the load strength of the overall structure. The inner wall of the bearing housing 2 is provided with an arc-shaped inner wall 34. The arc-shaped inner wall 34 is concentrically arranged with the arc-shaped outer ring 35, providing a stable working cavity for the internal moving parts. The steel ball 32 is rotatably connected within the arc-shaped inner wall 34. The spherical outer surface of the steel ball 32 and the concave arc surface of the arc-shaped inner wall 34 form a sliding fit, so that the steel ball 32 can rotate flexibly and swing at an angle within a certain range, so as to realize the adaptive adjustment of the angle between the parts and the transmission of force. To achieve long-term low-friction operation, the bearing housing 2 also integrates a sealing and lubrication system. Specifically, the bearing housing 2 has a lubrication cavity 45 for storing lubricating fluid, and a through oil injection hole 44 is provided on the top of the bearing housing 2. The oil injection hole 44 is connected to the lubrication cavity 45 to form a channel for adding lubricating fluid. In order to effectively seal the lubricating fluid inside the lubrication cavity 45, sealing rings 41 are fixedly connected to the inner wall of the bearing housing 2 and at the front and rear sides of the lubrication cavity 45, respectively.

[0025] Please refer to Figure 1 , Figure 3 and Figure 4 To facilitate installation and enhance connection stability, a base 31 is fixedly connected to the bottom of the connecting wall 1. The base 31 provides a flat mounting surface for the entire high-load radial bearing assembly to contact the base platform of external mechanical equipment. More specifically, to achieve a high-strength fastening connection, a connecting thread 33 is provided in the interior of the base 31 and the interior of the connecting wall 1. The connecting bolts or studs of the external equipment can be used to securely lock the entire bearing assembly in a predetermined position through the connecting thread 33. Please refer to Figure 4 To ensure the sealing performance of the lubrication system under various working conditions, the sealing ring 41 is specifically wrapped around the outer surface of the steel ball 32. The inner ring lip forms a tight dynamic seal with the outer surface of the steel ball 32. When the steel ball 32 rotates, the sealing ring 41 can prevent the lubricating fluid in the lubrication cavity 45 from leaking outwards, and also prevent external dust and impurities from entering the bearing housing 2. In addition, a sealing screw 43 is threaded to the top of the oil filling hole 44. By tightening or loosening the sealing screw 43, the oil filling hole 44 can be easily opened or closed. To further enhance the sealing reliability here, a second sealing ring 42 is also fixedly connected inside the oil filling hole 44 and below the sealing screw 43. The second sealing ring 42 is used to seal the assembly gap between the sealing screw 43 and the inner wall of the oil filling hole 44, forming a second sealing line to ensure that even in a vibrating environment, the lubricant will not leak from the oil filling hole 44.

[0026] As a preferred embodiment, refer to Figure 3 and Figure 4 The connecting mechanism 3 is composed of a connecting wall 1, a bearing seat 2, a base 31, a steel ball 32, a connecting thread 33, an arc-shaped inner wall 34, and an arc-shaped outer ring 35. These components work together to achieve high load bearing, stable installation connection, and flexible angle adjustment function. As another preferred embodiment, refer to Figure 3 and Figure 4 The sealing mechanism 4 is composed of sealing ring 1 41, sealing ring 2 42, sealing screw 43, oil injection hole 44 and lubrication cavity 45. These components form a complete and independent sealing and lubrication guarantee system, which ensures that the moving pair between steel ball 32 and arc-shaped inner wall 34 can be continuously and cleanly lubricated, thereby reducing the coefficient of friction and extending the service life of the assembly.

[0027] Working principle: During the connection and load-bearing process, the entire assembly is securely installed on the external equipment through the base 31 and the internal connecting thread 33. When the external load is applied to the component connected to the center hole of the steel ball 32, the force is transmitted to the steel ball 32 and then evenly distributed to the bearing seat 2 through the extensive contact surface between the steel ball 32 and the arc-shaped inner wall 34. The arc-shaped outer ring 35 structure of the bearing seat 2 further optimizes the stress transmission path. Finally, the force is reliably transmitted to the equipment foundation through the integrated connecting wall 1 and the base 31. During this process, if the connecting component deflects at an angle, the steel ball 32 will rotate freely within the arc-shaped inner wall 34 to adapt to this angle change, thereby realizing the dual functions of force transmission and angle adjustment. During lubrication and maintenance, when lubricant needs to be added, first loosen the sealing screw 43 located on the top of the bearing housing 2 to open the oil injection hole 44. Then, add an appropriate amount of lubricant to the lubrication cavity 45 inside the bearing housing 2 through the oil injection hole 44. After adding the lubricant, tighten the sealing screw 43 again. At this time, the lubricant is completely sealed inside the lubrication cavity 45. The sealing is achieved by two barriers: one is the sealing ring 42 located inside the oil injection hole 44, which prevents the lubricant from leaking from the thread gap of the sealing screw 43; the other is the sealing ring 41 located on the front and rear sides of the lubrication cavity 45, which fits tightly against the outer surface of the steel ball 32 to prevent the lubricant from leaking out from the movement gap. The lubricant stored in the lubrication cavity 45 can continuously provide lubrication for the contact surface between the steel ball 32 and the arc-shaped inner wall 34, which greatly reduces running friction and wear.
