Description

Technical Field

[0001] This utility model relates to bearings, and more particularly to a solid self-lubricating bearing with a release and flow guiding structure. Background Technology

[0002] Patent document CN216199854U discloses a self-lubricating bearing, which includes a cylindrical body with a cylindrical inner bore. The outer wall of the cylinder has several protrusions and recesses arranged alternately, smoothly connected. Several packing holes are provided on the outer wall of the cylinder, each containing a lubricating block. The packing holes are arranged in a row along the axial direction of the cylinder, and the rows of packing holes are evenly distributed along the circumference of the inner bore. By incorporating the protrusions and recesses, the contact area between the self-lubricating bearing and the bearing housing is increased without changing the overall length of the bearing, thus enabling it to withstand greater pressure. However, the lubricating blocks release lubricant only through the packing holes, resulting in low lubricant release efficiency and difficulty in quickly forming a uniform lubricating film. This leads to increased localized friction and wear, reducing reliability under complex operating conditions such as high speed, heavy load, or extreme temperatures. Therefore, it is necessary to optimize the structure to overcome these shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a solid self-lubricating bearing with a release and flow guiding structure to improve its lubrication performance.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A solid self-lubricating bearing with a release and flow guiding structure, comprising:

[0006] A support bracket is provided, which is adapted to the shape of the rotating shaft and the assembly shaft hole of the equipment. It can be installed in the assembly shaft hole, and the rotating shaft can be installed in the support bracket. The support bracket supports the rotating shaft, so that the rotating shaft can rotate in the assembly shaft hole through the support bracket.

[0007] A shaft hole positioning component is formed in the support bracket component and is adapted to the shape of the assembly shaft hole. The shaft hole positioning component positions the support bracket component in the assembly shaft hole.

[0008] A pivot positioning member is formed in the support bracket member and is adapted to the shape of the pivot. The pivot positioning member positions the pivot in the support bracket member.

[0009] A lubrication supply component is installed in the support bracket component and is engaged with the rotating shaft and the assembly shaft hole. The lubrication supply component applies lubricating material to the movement of the support bracket component in the assembly shaft hole and the movement of the rotating shaft in the support bracket component.

[0010] A lubrication release component is formed in the support bracket component and cooperates with the lubrication supply component and the rotating shaft. The lubrication release component assists in releasing the lubrication material of the lubrication supply component.

[0011] A lubrication guiding component is formed in the support support component, which corresponds to the position of the lubrication supply component and is connected to the lubrication release component. The lubrication guiding component guides the lubricating material between the support support component and the rotating shaft.

[0012] Specifically, the supporting components include:

[0013] The support cylinder is formed by rolling a metal substrate. Its outer wall is adapted to the shape of the assembly shaft hole and can be placed in and rotated in the assembly shaft hole. Its inner wall is adapted to the shape of the rotating shaft, which can pass through the support cylinder and rotate in the support cylinder. The support cylinder is provided with positioning holes. There are several positioning holes, each of which passes through both sides of the support cylinder radially and is evenly distributed along the circumference and axial direction of the support cylinder.

[0014] Shaft hole positioning components include:

[0015] A positioning protrusion ring is formed at one end of the outer wall of the support cylinder. It extends circumferentially along the support cylinder and protrudes radially outward from the support cylinder. It abuts against the positioning notch on the inner wall of the assembly shaft hole. The positioning protrusion ring axially positions the support cylinder in the assembly shaft hole.

[0016] The pivot positioning components include:

[0017] The positioning annular groove is formed at one end of the inner wall of the support cylinder. It extends circumferentially along the support cylinder and is recessed radially into the support cylinder. It abuts against the positioning shoulder on the outer wall of the rotating shaft. The positioning annular groove axially positions the rotating shaft in the support cylinder.

[0018] The lubrication supply components include:

[0019] The lubricating insert has several parts, each of which is embedded in the positioning hole and can rotate together with the support cylinder. Its inner wall abuts against the outer wall of the rotating shaft, and its outer wall abuts against the inner wall of the assembly shaft hole. When it rotates, it rubs off the outer wall of the rotating shaft and the inner wall of the assembly shaft hole to form a lubricating film.

[0020] The lubrication release component includes:

[0021] The release shaft groove is formed on the inner wall of the support cylinder. Several release shaft grooves are provided, each extending axially along the support cylinder and evenly distributed circumferentially. They pass through the lubrication block and form a release recess on the inner wall of the lubrication block to increase the contact angle between the lubrication block and the rotating shaft, so that the lubricating material in the lubrication block is quickly released and evenly transferred between the outer wall of the rotating shaft and the inner wall of the support cylinder.

[0022] The lubrication guiding components include:

[0023] The inner guide groove is provided with several components. Each inner guide groove is formed on the inner wall of the support cylinder and located between adjacent lubrication blocks. It extends along the circumference of the support cylinder and is evenly distributed along the axial direction of the support cylinder. The middle part of the release shaft groove intersects and communicates with the inner guide groove. The lubricating material in the release shaft groove can enter the inner guide groove, and the inner guide groove stores and guides the lubricating material.

[0024] The outer guide groove is provided in pairs. Each outer guide groove is formed at both ends of the inner wall of the support cylinder. It extends along the circumference of the support cylinder and intersects and connects with both ends of the release shaft groove. The lubricating material in the release shaft groove can enter the outer guide groove, and the outer guide groove stores and guides the lubricating material.

[0025] In one embodiment of this utility model, the axial width and radial depth of the outer guide groove are greater than the axial width and radial depth of the inner guide groove, which can store more lubricating material and prevent the lubricating material from flowing out from both ends of the support cylinder.

[0026] The advantages of this utility model are:

[0027] The self-lubricating bearing features a release groove, an inner guide groove, and an outer guide groove, allowing the lubricant to be evenly distributed between the shaft and the support cylinder, forming a stable lubricating film. Simultaneously, the guide groove provides a flow channel for the lubricant, ensuring it quickly reaches the areas requiring lubrication and preventing localized insufficient lubrication. The guide groove increases the surface area of ​​the support cylinder, improving heat dissipation and preventing lubricant failure or bearing material damage due to frictional heat. This allows the bearing to maintain good lubrication even under high speed, heavy load, or extreme temperatures, adapting to complex working conditions. The outer guide groove is wider and deeper than the inner guide groove, storing more lubricant and preventing it from flowing out from both ends of the support cylinder, ensuring long-lasting lubrication and significantly extending the bearing's service life, thus improving overall performance and reliability.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] like Figure 1 , Figure 2 As shown, the solid self-lubricating bearing with a release and guiding structure proposed in this utility model includes a support component, a shaft hole positioning component, a rotating shaft positioning component, a lubrication supply component, a lubrication release component, and a lubrication guiding component. The support component is adapted to the shape of the rotating shaft and the assembly shaft hole of the equipment, and can be installed in the assembly shaft hole. The rotating shaft can be installed in the support component, which supports the rotating shaft, allowing it to rotate in the assembly shaft hole. The shaft hole positioning component is formed in the support component and is adapted to the shape of the assembly shaft hole. The shaft hole positioning component positions the support component in the assembly shaft hole. The rotating shaft positioning component is formed in the support component and is adapted to the shape of the rotating shaft. The system is adapted to the rotating shaft. The rotating shaft positioning component positions the rotating shaft within the support bracket. The lubrication supply component is installed within the support bracket and mates with the rotating shaft and the assembly shaft hole. The mating lubrication component applies lubricating material to the movement of the support bracket within the assembly shaft hole and the movement of the rotating shaft within the support bracket. The lubrication release component is formed within the support bracket and mates with the lubrication supply component and the rotating shaft. The lubrication release component assists in releasing the lubricating material from the lubrication supply component. The lubrication guide component is formed within the support bracket, corresponding to the position of the lubrication supply component and connecting with the lubrication release component. The lubrication guide component guides the lubricating material between the support bracket and the rotating shaft.

[0032] In this embodiment, the support support component includes a support cylinder 100. The support cylinder is formed by rolling a metal substrate. Its outer wall is adapted to the shape of the assembly shaft hole and can be placed in the assembly shaft hole and rotate in the assembly shaft hole. Its inner wall is adapted to the shape of the rotating shaft. The rotating shaft can pass through the support cylinder and rotate in the support cylinder. The support cylinder is provided with positioning holes 110. There are several positioning holes. Each positioning hole passes through both sides of the support cylinder radially and is evenly arranged along the circumference and axial direction of the support cylinder.

[0033] The shaft hole positioning component includes a positioning protrusion ring 200, which is formed at one end of the outer wall of the support cylinder. It extends circumferentially along the support cylinder and protrudes radially outward from the support cylinder. It abuts against the positioning recess on the inner wall of the assembly shaft hole. The positioning protrusion ring axially positions the support cylinder in the assembly shaft hole.

[0034] The rotating shaft positioning component includes a positioning ring groove 300, which is formed at one end of the inner wall of the support cylinder. It extends circumferentially along the support cylinder and is recessed radially into the support cylinder. It abuts against the positioning shoulder on the outer wall of the rotating shaft. The positioning ring groove axially positions the rotating shaft in the support cylinder.

[0035] The lubrication supply component includes several lubrication inserts 400, each embedded in a positioning hole. These inserts rotate with the support cylinder, their inner walls abutting against the outer wall of the rotating shaft, and their outer walls abutting against the inner wall of the assembly shaft hole. During rotation, they rub against the outer wall of the rotating shaft and the inner wall of the assembly shaft hole, forming a lubricating film. In this embodiment, the lubrication insert is made of graphite or polymer composite material; its structure and principle are existing technologies and therefore not described in detail.

[0036] The lubrication release component includes several release grooves 500, which are formed in the inner wall of the support cylinder. Each release groove extends axially along the support cylinder and is evenly distributed circumferentially. They penetrate through the lubrication inserts, forming release recesses on the inner wall of the lubrication inserts to increase the contact angle between the lubrication inserts and the rotating shaft. This allows the lubricating material in the lubrication inserts to be quickly released and evenly transferred between the outer wall of the rotating shaft and the inner wall of the support cylinder. Simultaneously, the number of release grooves is less than the number of circumferential lubrication inserts, ensuring that only a portion of the inner wall of the lubrication inserts has release recesses.

[0037] The lubrication guiding component includes an inner guiding groove 610 and an outer guiding groove 620. The inner guiding groove is provided with several parts, each of which is formed on the inner wall of the support cylinder and located between adjacent lubrication blocks. It extends circumferentially along the support cylinder and is evenly distributed along the axial direction of the support cylinder. The middle part of the release shaft groove intersects and communicates with the inner guiding groove. The lubricating material in the release shaft groove can enter the inner guiding groove, where it is stored and guided. There is a pair of outer guiding grooves, each of which is formed at both ends of the axial direction of the inner wall of the support cylinder. It extends circumferentially along the support cylinder and intersects and communicates with both ends of the release shaft groove. The lubricating material in the release shaft groove can enter the outer guiding groove, where it is stored and guided.

[0038] In this embodiment, the axial width and radial depth of the outer guide groove are greater than those of the inner guide groove, allowing for the storage of more lubricating material and preventing it from flowing out from both ends of the support cylinder. It should be noted that, to make the structure more clearly visible, the outer guide groove, inner guide groove, and release shaft groove in the figure are enlarged for display purposes; their actual dimensions are smaller to avoid excessive accumulation of lubricating material, which could affect the amount of lubricating material in other parts.
