Description

Technical Field

[0001] The present invention belongs to the technical field of roller bearings, and particularly relates to a high-strength composite roller bearing for a forklift mast. Background Art

[0002] As an important component for carrying heavy loads and performing lifting operations, the forklift mast needs to be able to withstand large loads. The high-strength composite roller bearing can provide stronger support when carrying heavy loads, avoid damage to the bearing due to excessive load, and ensure the stability of the forklift mast in a high-load environment. The combination of composite materials and high-strength design can effectively improve the wear resistance and corrosion resistance of the bearing, and extend the service life of the forklift mast. During the operation of the forklift, it often faces multiple liftings and high-frequency use. The durability of the bearing directly affects the long-term reliability and maintenance frequency of the forklift. And the forklift usually works in complex environments such as factories and warehouses. Dust, moisture and extreme temperatures in the environment may damage traditional bearings. High-strength composite materials have stronger anti-pollution, high-temperature resistance, corrosion resistance and other properties, meeting the working requirements in harsh environments.

[0003] After long-term use of existing bearings, the bearings may be worn or damaged, especially under large loads, excessive friction or lack of lubrication. The worn bearings may cause the mast to shake, especially during the lifting process. Due to the increase in bearing clearance, the stability of the mast is affected. And if the goods carried by the forklift mast during the lifting operation are uneven or exceed the rated load-bearing capacity of the bearing, it may cause the bearing to be overloaded, thus triggering a shaking problem. Moreover, heat is generated due to friction during the operation of the bearing, especially under high-speed operation or high load, the temperature will rise rapidly. When the temperature is too high, the metal material of the bearing will be affected by thermal expansion, which may cause the bearing size to change, thus affecting its accuracy and operation stability. Overheating may also cause the lubricating oil of the bearing to deteriorate or the oil film to rupture, unable to effectively reduce friction, further exacerbating wear. Seriously, overheating will cause the bearing to burn out or completely fail. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a high-strength composite roller bearing for a forklift mast.

[0005] The technical solution adopted to solve the above technical problem is: a high-strength composite roller bearing for a forklift mast, including a mounting frame. The interior of the mounting frame is provided with a hollow structure, and a plurality of through grooves are penetrated through both sides of the mounting frame. The plurality of through grooves are arranged in a circumferential symmetry. A bearing stabilizing mechanism is arranged at the center of the interior of the mounting frame.

[0006] Through the above technical solutions, it is possible to maintain a low wear rate during long-term use, extend the service life, reduce frequent maintenance and replacement, thereby improving the overall efficiency and economy of the forklift. Moreover, it can work stably for a long time in a high-temperature environment. When the forklift is operating under high load or high speed, it will generate a relatively high temperature. The composite bearing can effectively cope with these temperature changes and avoid failures or damages caused by overheating.

[0007] Furthermore, the bearing stabilizing mechanism includes an inner shaft ring. Gaskets are fixedly connected to both sides of the inner shaft ring. The side of the gasket away from the inner shaft ring is parallel to the outer wall of the mounting bracket. A plurality of mounting holes are penetrated and opened between the inner shaft ring and the gasket.

[0008] Through the above technical solutions, it can ensure that the bearing is well-centered in six directions. Even if the forklift undergoes slight offsets during operation due to uneven loads or the movement of the mast, the bearing stabilizing mechanism can restore the relative position of the bearing through elasticity, ensuring that the bearing always operates at the optimal working position and avoiding uneven friction or excessive wear caused by offsets.

[0009] Furthermore, the plurality of mounting holes are arranged in a circumferentially symmetric distribution. An outer shaft ring is arranged outside the inner shaft ring. A plurality of balls are slidably connected between the outer shaft ring and the inner shaft ring, and the outer shaft ring limits the balls.

[0010] Through the above technical solutions, the flexibility of the bearing stabilizing mechanism can adapt to some slight installation deviations, avoid the bearing from being subjected to uneven loads or torques due to installation problems, thereby improving the tolerance and reliability of the assembly. At the same time, it can also reduce the noise generated when the bearing directly contacts hard objects or is subjected to strong impacts. By mitigating these impacts, the bearing stabilizing mechanism can effectively reduce the wear rate of the bearing and extend its service life.

[0011] Furthermore, a plurality of connecting seats are fixedly connected to the outer wall of the outer shaft ring. The plurality of connecting seats are arranged in a circumferentially symmetric distribution. A connecting member is rotatably connected to the side of the connecting seat away from the outer shaft ring.

[0012] Through the above technical solutions, through elastic connections in six directions, the load of the bearing can be more evenly distributed, avoiding local overload. The bearing stabilizing mechanism can help disperse the forces transmitted from all directions, enabling the bearing to maintain higher stability and load-bearing capacity under multi-directional loads, thereby reducing failures and damages caused by overload.

[0013] Furthermore, the other end of the connecting member is fixedly connected to a sliding rod. The sliding rod is slidably connected through a frame. The frame is arranged in a square structure. The sliding rod is fixedly connected through a sliding plate. The sliding plate is located inside the frame, and the sliding plate is slidably connected to the frame.

[0014] Further, one side of the skateboard is fixedly connected with a spring, the other end of the spring is fixedly connected with the frame, one end of the sliding rod far from the connecting piece is fixedly connected with a fixing plate, the other end of the fixing plate penetrates and is rotatably connected with a fixing rod, and both ends of the fixing rod are fixedly connected with the inner wall of the mounting bracket.

[0015] Further, a plurality of connecting frames are fixedly connected to the side of the gasket far from the inner shaft collar. The plurality of connecting frames are arranged in a circumferentially symmetric distribution, and the connecting frames are arranged in a U-shaped structure.

[0016] Further, the connecting frame is located at the center line between two mounting holes. One side of the connecting frame is slidably connected with the outer wall of the mounting bracket. A fan blade is rotatably connected to the end of the connecting frame far from the gasket. Both side walls of the fan blade are parallel and coincide with both side walls of the connecting frame.

[0017] Through the above technical solutions, by blowing air to reduce the bearing temperature and improve its lubrication effect, the bearing can operate in a more efficient and stable state, reducing failures caused by factors such as overheating and poor lubrication. This helps to improve the working efficiency of the entire equipment, reduce downtime, and extend the overall service life of the equipment.

[0018] The beneficial effects of the present invention are as follows: (1) In the present invention, relative rotation is generated between the connecting piece and the connecting seat. The components connected to one side of the connecting piece rotate simultaneously. Moreover, relative sliding occurs between the sliding rod and the frame, the spring contracts, and relative rotation occurs between the fixing plate connected to one end of the sliding rod and the fixing rod. Through six-direction support, the load of the bearing can be more evenly distributed, avoiding local overload, helping to disperse the forces transmitted from all directions, enabling the bearing to maintain higher stability and load-bearing capacity under multi-directional loads, thereby reducing failures and losses caused by overload; (2) In the present invention, the rotation of the bearing drives the gasket to rotate simultaneously, and then the connecting frame rotates. When the fan blade connected to one end of the connecting frame rotates, since one side of the fan blade coincides with the connecting frame, when the fan blade rotates a certain angle following the connecting frame, under the action of gravity, the fan blade rotates in the opposite direction, and so on in a cycle, thereby generating an air duct to suck air into the mounting bracket through the through groove, performing an air supply process on the bearing, which can reduce the temperature and make the bearing operate more stably. The air flow helps to evenly distribute the temperature and air flow around the bearing, avoiding problems such as local overheating or excessive temperature difference, thereby reducing deformation and failure caused by uneven heat distribution.

Specific embodiments

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] As Figures 1-4As shown, a high-strength composite roller bearing for a forklift mast in this embodiment includes a mounting frame 1. The inside of the mounting frame 1 is hollow, and a number of through slots 2 are provided through both sides of the mounting frame 1. The number of through slots 2 is arranged in a circumferential symmetry. A bearing stabilizing mechanism is provided at the center of the inside of the mounting frame 1, which can maintain a low wear rate during long-term use, extend the service life, reduce frequent maintenance and replacement, thereby improving the overall efficiency and economy of the forklift. Moreover, it can work stably for a long time in a high-temperature environment. When the forklift is under high load or high-speed operation, a relatively high temperature will be generated. The composite bearing can effectively cope with these temperature changes and avoid failures or damages caused by overheating. The bearing stabilizing mechanism includes an inner shaft ring 7. Gaskets 5 are fixedly connected to both sides of the inner shaft ring 7. A number of connecting frames 3 are fixedly connected to the side of the gasket 5 away from the inner shaft ring 7, which can ensure that the bearing is well centered in six directions. Even if the forklift undergoes slight deviations during operation due to uneven loads or the movement of the mast, the bearing stabilizing mechanism can restore the relative position of the bearing through elasticity, ensuring that the bearing always operates at the optimal working position and avoiding uneven friction or excessive wear caused by deviations. The connecting frame 3 is located at the center line between two mounting holes 6. One side of the connecting frame 3 is slidably connected to the outer wall of the mounting frame 1. The flexibility of the bearing stabilizing mechanism can adapt to some slight installation deviations, avoiding uneven loads or torques on the bearing caused by installation problems, thereby improving the assembly tolerance and reliability. At the same time, it can also reduce the noise generated when the bearing directly contacts hard objects or is subjected to strong impacts. By buffering these impacts, the bearing stabilizing mechanism can effectively reduce the wear rate of the bearing and extend its service life. The end of the connecting frame 3 away from the gasket 5 is rotatably connected to a fan blade 4. The two side walls of the fan blade 4 are parallel and coincide with the two side walls of the connecting frame 3. The number of connecting frames 3 is arranged in a circumferential symmetry. Through elastic connections in six directions, the load on the bearing can be more evenly distributed, avoiding local overload. The bearing stabilizing mechanism can help disperse the forces transmitted from all directions, enabling the bearing to maintain higher stability and load-bearing capacity under multi-directional loads, thereby reducing failures and damages caused by overload. And the connecting frame 3 is arranged in a U-shaped structure, and the side of the gasket 5 away from the inner shaft ring 7 is parallel to the outer wall of the mounting frame 1.

[0026] As Figures 2-4As shown, a number of mounting holes 6 are drilled through between the inner shaft ring 7 and the gasket 5. The number of mounting holes 6 is arranged in a circumferential symmetry. An outer shaft ring 9 is arranged on the outside of the inner shaft ring 7. A number of connecting seats 10 are fixedly connected to the outer wall of the outer shaft ring 9. The number of connecting seats 10 is arranged in a circumferential symmetry. One end of the connecting seat 10 away from the outer shaft ring 9 is rotatably connected to a connecting member 11. In some working environments, moisture and water can corrode the bearing, affecting its performance and lifespan. Air supply can help keep the bearing dry, prevent the accumulation of moisture, and reduce the corrosion risk, which is particularly effective in high-humidity environments. The other end of the connecting member 11 is fixedly connected to a sliding rod 13. The sliding rod 13 is slidably connected through a frame 12. The frame 12 is arranged in a square structure. The sliding rod 13 is fixedly connected through a sliding plate 15. Air supply can not only reduce the temperature but also make the bearing operate more stably. The air flow helps to evenly distribute the temperature and air flow around the bearing, avoiding problems such as local overheating or excessive temperature difference, thereby reducing deformation and failure caused by uneven heat distribution. One side of the sliding plate 15 is fixedly connected to a spring 14. The other end of the spring 14 is fixedly connected to the frame 12, which helps the forklift mast to operate smoothly in a complex operating environment. Especially in working states such as load lifting and rapid movement, it can ensure the accuracy and stability of the mast movement. The end of the sliding rod 13 away from the connecting member 11 is fixedly connected to a fixing plate 16. The other end of the fixing plate 16 is rotatably connected through a fixing rod 17. Both ends of the fixing rod 17 are fixedly connected to the inner wall of the mounting bracket 1. The sliding plate 15 is located inside the frame 12, and the sliding plate 15 is slidably connected to the frame 12. A number of balls 8 are slidably connected between the outer shaft ring 9 and the inner shaft ring 7. By supplying air to reduce the bearing temperature and improve its lubrication effect, the bearing can operate in a more efficient and stable state, reducing faults caused by factors such as overheating and poor lubrication. This helps to improve the working efficiency of the entire equipment, reduce downtime, and extend the overall service life of the equipment. Moreover, the outer shaft ring 9 limits the balls 8.

[0027] The working principle of this embodiment is as follows. By installing the overall component on the forklift mast, during use, when the bearing wears due to long-term use or the goods carried by the forklift mast during lifting operation are uneven and exceed the rated load-bearing capacity of the bearing, when the inner shaft ring 7 and the outer shaft ring 9 and the balls 8 inside them shake, the connecting piece 11 and the connecting seat 10 rotate relative to each other. The component connected to one side of the connecting piece 11 rotates simultaneously. Moreover, the sliding rod 13 and the frame 12 slide relative to each other, the spring 14 contracts, and the fixing plate 16 connected to one end of the sliding rod 13 and the fixing rod 17 rotate relative to each other to adapt to the rotation angle of the connecting piece 11 and the connecting seat 10. Through shock absorption and support in six directions, the bearing can maintain balance and stability when bearing forces in different directions. No matter how the forklift mast lifts or the load changes, the spring 14 can dynamically adjust the position of the bearing to ensure its stable operation, thereby improving the stability and accuracy of the entire forklift system and avoiding operation problems caused by instability.

[0028] Moreover, when the inner shaft ring 7 rotates, it drives the gasket 5 to rotate simultaneously, and then makes the connecting frame 3 rotate. When the fan blade 4 connected to one end of the connecting frame 3 rotates, since one side of the fan blade 4 coincides with the connecting frame 3, therefore, when the fan blade 4 follows the connecting frame 3 and rotates a certain angle, under the action of gravity, the fan blade 4 rotates in the opposite direction, and so on in a cycle, thereby generating an air duct to suck air through the through slot 2 into the mounting frame 1 to perform the air supply process for the bearing, which helps to reduce the temperature around the bearing, thereby delaying the process of lubricating oil deterioration, maintaining the performance of the lubricating oil, and extending the service life of the lubricating oil.

[0029] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
