Abstract
Description
Technical Field
[0001] The invention relates to the technical field of mechanical lubrication, and specifically discloses a micro-bead lubricating oil generator and a micro-bead oil generating method thereof. Background Art
[0002] Currently, there are many ways to achieve mechanical lubrication with liquid lubricants, mainly including forced circulation lubrication, oil bath lubrication, oil mist lubrication and oil-gas lubrication.
[0003] Forced circulation lubrication is to use a lubricating oil circulation pump to continuously spray oil to the parts that need lubrication (large bearings, gears, etc.) to achieve lubrication and cooling. However, this lubrication system is complex and difficult to manage. It is generally only used for large motion mechanisms. The advantages are reliable systems and high efficiency. Oil bath lubrication is more commonly used for bearings with low power and simple structures. The advantages are simple structure, small footprint, and the use of the cavity of the bearing seat to hold a sufficient amount of lubricating oil. However, it is inefficient and cannot stabilize the quality of the lubricating oil. It can only be replaced regularly. It is easy to generate heat and has poor heat dissipation effect, resulting in a large waste of lubricating oil. Oil mist lubrication is to atomize the lubricating oil and allow it to flow to any position that needs lubrication. However, a special nozzle is required to condense it again near the lubrication point. It has a better lubrication effect on rolling bearings and is suitable for clustered pump lubrication of multiple sets of machines. However, the system is complex and requires the laying of large oil mist delivery pipelines. In addition, there is exhaust gas discharged from the lubrication point, which is easy to pollute the environment. Oil-gas lubrication uses compressed air to drive liquid lubricant to spray to the required lubrication points. The advantage is that it can lubricate the equipment at the same time, and because the liquid lubricant is sprayed and the amount is controllable, the lubrication effect is better and the environmental pollution is small. The disadvantage is that the lubrication points need to be modified to meet the needs of oil-gas lubrication.
[0004] Micro-bead oil lubrication is a new type of mechanical lubrication method. Its principle is to process liquid lubricating oil into micro-bead lubricating oil with a size between 30 and 70 um, so that its flow characteristics are between gas and liquid and it is semi-suspended, and then pass it into the transmission machinery through compressed air, so that it contacts with the transmission parts to achieve rapid sedimentation and film formation, thereby achieving a lubrication effect. Compared with traditional oil mist lubrication, micro-bead oil lubrication can make the micro-bead oil contact with the surface of the transmission parts to form a film quickly, and it is not easy to be carried out of the transmission cavity under the action of airflow, so that it can fully contact with the transmission parts to achieve lubrication. However, due to the lack of such equipment on the market that can prepare liquid lubricating oil into micro-bead oil of a specific size, micro-bead oil lubrication cannot be effectively applied. Therefore, this application proposes a newly designed micro-bead lubricating oil generator, which can realize the formation of micro-bead lubricating oil during micro-bead lubrication and realize the micro-bead lubrication method of transmission machinery. Summary of the invention
[0005] The purpose of the present invention is to provide a micro-bead lubricating oil generator and a micro-bead oil generating method thereof, so that liquid lubricating oil and compressed air can react to form micro-bead lubricating oil with a semi-suspended state, thereby providing a new micro-bead lubrication method for mechanical transmission.
[0006] The present invention is achieved through the following technical solutions: A micro-bead lubricating oil generator comprises a body and a cover body, wherein a conical reflux slot is provided at the center of the body, an oil blind hole and a micro-bead oil blind hole are provided on the outside of the conical reflux slot, and both the oil blind hole and the micro-bead oil blind hole are connected with the upper end of the conical reflux slot through a connecting channel, an impact convex tooth is provided on the inner wall of the upper end of the conical reflux slot located between the fan-shaped angles of the oil blind hole and the micro-bead oil blind hole, a gas inlet passage leading into the upper end of the conical reflux slot along a tangential direction is provided in the body, and an oil inlet hole and a micro-bead oil outlet hole corresponding to the oil blind hole and the micro-bead oil blind hole are provided on the cover body.
[0007] As a further configuration of the above scheme, an air flow annular groove is concentrically opened on the body located outside the conical reflux slot, an air inlet hole connected to the air flow annular groove is opened at the lower end of the cover body or the body, and the outer end of the gas inlet duct is connected to the air flow annular groove.
[0008] As a further configuration of the above scheme, a plurality of impact cams on the inner wall of the upper end of the conical reflow slot are continuously arranged, and the raised side ends of the impact cams are perpendicular to the swirl direction of the compressed gas in the conical reflow slot.
[0009] As a further configuration of the above solution, the cover body is sealed and fixedly connected to the upper end of the body through a connecting piece.
[0010] The present invention also discloses a method for using the micro-bead lubricant generator to generate micro-bead lubricant, which comprises the following steps: S1: Pass liquid lubricating oil into the oil blind hole, and perform negative pressure suction on the micro-bead oil blind hole; S2: The compressed gas is introduced into the gas inlet passage, so that the compressed gas enters the upper end of the conical reflux slot hole along the tangential direction. After entering the conical reflux slot hole, the compressed gas rotates and flows along the inner wall and acts on the liquid lubricating oil flowing out of the oil blind hole, so that the compressed gas and the liquid lubricating oil flow toward the impact convex teeth together. The density difference and speed difference between the liquid lubricating oil and the airflow are used to force the liquid lubricating oil to change direction on the impact convex teeth for cutting and separation, thereby forming micro-beads of oil with a diameter between 30 and 70 μm. S3: The formed micro-bead oil flows to the micro-bead oil blind hole with the compressed gas and is extracted by negative pressure for use. At the same time, the micro-bead oil that has not been extracted and the liquid lubricating oil that has not been cut and separated are re-polymerized in the conical reflux groove hole for recovery. Beneficial Effects
[0011] The micro-bead lubricating oil generator disclosed in this patent has a simple and ingenious structural design. It uses compressed air to drive the liquid lubricating oil to rotate and flow, and during the flow process, it interacts with the impact convex teeth to achieve cutting and separation, thereby forming semi-suspended micro-bead oil. The flow characteristics of the micro-bead oil are between those of gas and liquid. On the one hand, it can be introduced into the position of the friction pair of the transmission machinery for lubrication under relatively small power, effectively solving the lubrication problem of complex structures. On the other hand, the formed micro-bead oil is easier to settle on the surface of the object and quickly form an oil film for lubrication compared with oil mist lubrication, thereby improving the lubrication effect.

[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 3 , and describes the application in detail with reference to embodiments. Example 1
[0016] Embodiment 1 discloses a micro-bead lubricant generator, including a disc-shaped body 1 and a cover 2 that is sealed with the upper end of the body 1. The cover 2 and the body 1 can be fixedly connected by a connector or connected in other ways. A conical reflux groove 101 that is concave downward is provided on the upper surface of the body 1, and an airflow annular groove 102 is concentrically provided on the upper surface of the body 1 outside the conical reflux groove 101. Then, an air inlet 201 that is connected to the airflow annular groove 102 is provided on the cover 2, or an air inlet that is connected to the airflow annular groove 102 is directly provided on the lower surface of the body 1, so that compressed air can enter through the air inlet 201 and then flow in an annular manner along the airflow annular groove 102.
[0017] A gas inlet duct 103 is provided on the upper surface of the body 1 between the airflow annular groove 102 and the conical reflux slot 101, and the gas inlet duct 103 is arranged along the tangent direction of the upper end of the conical reflux slot 101, and the two ends of the gas inlet duct 103 are respectively connected with the conical reflux slot 101 and the airflow annular groove 102, so that when the airflow annular groove 102 enters the conical reflux slot 101 along the gas inlet duct 103, a swirl flow interacting with the inner wall thereof can be formed.
[0018] The body 1 is provided with an oil blind hole 104 and a micro-bead oil blind hole 105, and the inner side ends of the oil blind hole 104 and the micro-bead oil blind hole 105 are connected to the upper end of the conical reflux slot 101 through the opening of the connecting channel 106. A plurality of continuous impact convex teeth 107 are arranged on the inner wall of the upper end of the conical reflux slot 101 between the fan-shaped angles of the oil blind hole 104 and the micro-bead oil blind hole 105, and the convex side ends of the impact convex teeth 107 are perpendicular to the swirl direction of the compressed gas in the conical reflux slot 101. Finally, the upper surface of the cover body 2 is provided with an oil inlet hole 202 corresponding to the oil blind hole 104 and a micro-bead oil outlet hole 203 corresponding to the micro-bead oil blind hole 105.
[0019] The specific working principle of the micro-bead lubricating oil generator disclosed in this embodiment 1 and the process of producing micro-bead oil are as follows: The compressed air and liquid lubricating oil are respectively introduced into the air inlet 201 and the oil blind hole 104, and then the compressed air enters the airflow ring groove 102, and then enters the upper end of the tapered reflux slot 101 along the tangential direction through the gas inlet duct 103. At this time, the liquid lubricating oil in the oil blind hole 104 enters the upper end of the tapered reflux slot 101 through the connecting channel 106, and is rotated and flows along the upper inner wall of the tapered reflux slot 101 under the action of the compressed air. During the flow process, due to the design of the impact convex teeth 107, the smooth flow of the liquid lubricating oil and the compressed air is hindered, and they are forced to change direction on the impact convex teeth for cutting and separation by using their density difference and speed difference, thereby forming spherical liquid lubricating oil particles with a diameter of 30 to 70 microns. Finally, it enters the micro-bead oil blind hole 105 through the connecting channel 106 and is pumped out from the micro-bead oil outlet hole 203. The micro-bead oil that is not pumped out and the liquid lubricating oil that is not cut and separated are re-polymerized in the contraction acceleration at the lower end of the conical reflux groove hole 101, and then return to the oil tank from the oil return channel for recycling, completing a micro-bead generation cycle.
[0020] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
