Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a novel self-lubricating bearing for a hoist. Background Art

[0002] Bearings are components used to determine the relative motion position of rotating shafts and other parts, primarily providing support or guidance. Their core function is to support rotating mechanical elements and reduce the friction coefficient of mechanical loads during transmission. Bearings can be divided into two categories: rolling bearings and plain bearings, depending on the friction properties of the moving elements. In existing technology, most elevators typically use self-lubricating bearings. These bearings have built-in lubricant that automatically releases lubricant during operation, reducing friction and wear, reducing maintenance requirements, and improving durability.

[0003] However, although the new self-lubricating bearings currently used in most elevators can automatically lubricate through built-in lubricants, their oil flow regulation is not ideal and cannot be flexibly adjusted according to actual usage. This may result in failure to obtain the best lubrication effect, which in turn affects the friction and wear conditions of the bearings.

[0004] Therefore, those skilled in the art provide a novel self-lubricating bearing for a hoist to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present utility model is to solve the shortcomings of the prior art and to propose a new self-lubricating bearing for a hoist. When in use, the bearing adjusts the gap between the threaded cap and the air inlet pipe by rotating the provided threaded cap to change the size of the air inlet hole, thereby controlling the flow of lubricating oil from the oil outlet hole in the cavity within the inner ring, so that the flow of lubricating oil can be adjusted according to actual needs, thereby ensuring that the bearing obtains the best lubrication effect and reduces friction and wear.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A novel self-lubricating bearing for a hoist, comprising an inner ring and an outer ring, an air inlet hole being provided in the middle of one side of the upper end of the inner ring, a threaded cap being threadedly connected to the middle of one side of the inner upper end of the inner ring, an air inlet pipe being fixedly connected to one side of the inner upper end of the inner ring, a cavity being provided in the middle of the inner ring, an inner wall of the inner ring and an outer wall of the outer ring being provided with a hardened layer, an anti-corrosion layer being provided on one side of both hardened layers, a wear-resistant coating being provided on one side of both anti-corrosion layers, and an oil outlet hole being provided in the middle of the lower end of the inner ring;

[0008] Through the above technical solution, when the bearing is in use, the gap between the threaded cap and the intake pipe is adjusted by rotating the set threaded cap to change the size of the intake hole, thereby controlling the flow of lubricating oil from the oil outlet hole in the cavity inside the inner ring, so that the flow of lubricating oil can be adjusted according to actual needs, thereby ensuring that the bearing obtains the best lubrication effect and reduces friction and wear.

[0009] Furthermore, an oiling nozzle is provided on one side of the inner upper end of the inner ring;

[0010] Through the above technical solution, lubricating oil can be conveniently injected into the bearing through the oil injection nozzle, which helps to maintain the normal operation of the internal lubrication system, reduce friction, reduce wear, thereby extending the service life of the bearing and improving its operating smoothness and efficiency.

[0011] Furthermore, a plurality of balls are evenly spaced and rolling between the inner ring and the outer ring;

[0012] Through the above technical solution, the evenly distributed balls can effectively disperse the load borne by the bearing, improve its stability and load-bearing capacity, thereby reducing vibration and noise during operation and ensuring smooth rotation performance.

[0013] Furthermore, the two hardened layers are both made of titanium aluminum nitride material;

[0014] Through the above technical solution, the aluminum titanium nitride hardened layer has excellent hardness and wear resistance, which can significantly improve the wear resistance and service life of the bearing and reduce damage under high load and high wear conditions.

[0015] Furthermore, the two anti-corrosion layers are both made of metallic zinc material;

[0016] Through the above technical solution, the zinc anti-corrosion layer can effectively resist corrosion, especially in humid or corrosive environments, protecting the bearing surface from environmental influences, thereby improving its durability and reliability.

[0017] Furthermore, both of the wear-resistant coatings are made of silicon nitride material;

[0018] Through the above technical solutions, silicon nitride coating provides excellent wear resistance and low friction coefficient, which can effectively reduce friction and wear, improve bearing durability, and maintain stable operating performance.

[0019] Furthermore, the threaded cap and the air intake pipe are located at the same position inside the inner ring, and one end surface of the threaded cap and the air intake pipe corresponds to each other;

[0020] Through the above technical solution, the gas exchange process is optimized by the correspondence between one end surface of the threaded cap and the air inlet pipe, which helps to regulate the gas circulation inside the bearing and improves the adaptability and reliability of the bearing.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a new self-lubricating bearing for a hoist. When in use, the bearing adjusts the gap between the threaded cap and the air inlet pipe by rotating the provided threaded cap to change the size of the air inlet hole, thereby controlling the flow of lubricating oil from the oil outlet hole in the cavity within the inner ring. The flow of lubricating oil can be adjusted according to actual needs, thereby ensuring that the bearing obtains the best lubrication effect and reduces friction and wear. In addition, this adjustment mechanism can also adapt to different operating conditions and load requirements, thereby improving the adaptability and reliability of the bearing.

[0023] 2. The utility model proposes a new type of self-lubricating bearing for an elevator. When in use, the hardness of the bearing surface can be effectively improved by arranging a hardening layer, an anti-corrosion layer and a wear-resistant coating on the inner wall of the inner ring and the outer wall of the outer ring, thereby enhancing its ability to resist plastic deformation. At the same time, it can effectively prevent the bearing from being corroded by environmental factors, reduce friction and wear, and protect the surface integrity of the bearing during continuous operation, thereby improving the mechanical strength and durability of the bearing.

When the bearing is in use, the gap between the threaded cap 4 and the air inlet pipe 11 is adjusted by rotating the threaded cap 4 to change the size of the air inlet hole 5, thereby controlling the flow of lubricating oil in the cavity 6 of the inner ring 1 from the oil outlet hole 12, so that the flow of lubricating oil can be adjusted according to actual needs, thereby ensuring that the bearing obtains the best lubrication effect and reduces friction and wear.

[0032] An oiling nozzle 3 is provided on one side of the inner upper end of the inner ring 1, through which lubricating oil can be easily injected into the bearing, which helps to maintain the normal operation of the internal lubrication system, reduce friction, reduce wear, thereby extending the service life of the bearing and improving its running stability and efficiency. A plurality of balls 7 are evenly spaced and rolling between the inner ring 1 and the outer ring 2. The evenly distributed balls 7 can effectively disperse the load borne by the bearing, improve its stability and load-bearing capacity, thereby reducing vibration and noise during operation and ensuring smooth rotation performance. The two hardened layers 8 are both made of aluminum titanium nitride material. The aluminum titanium nitride hardened layer 8 has excellent hardness and wear resistance, which can significantly improve the wear resistance and service life of the bearing and reduce damage under high load and high wear conditions. Bad, the two anti-corrosion layers 9 are made of metallic zinc material, and the zinc anti-corrosion layer 9 can effectively resist corrosion, especially in humid or corrosive environments, protecting the bearing surface from environmental influences, thereby improving its durability and reliability. The two wear-resistant coatings 10 are made of silicon nitride material.
