Description

Technical Field

[0001] The utility model relates to the technical field of mechanical lubrication, and specifically discloses a dumbbell-shaped micro-bead oil dispenser. Background Art

[0002] At present, the common layouts of liquid oil lubrication include four mainstream methods: oil bath splash lubrication, forced lubrication direct injection lubrication, oil mist lubrication, and oil-gas lubrication. Among them, simple oil bath splash lubrication is prone to generate a large amount of heat and the lubricating oil ages quickly, which belongs to a backward lubrication method and is usually used in light-load modes with simple structures; forced lubrication direct injection lubrication generally uses an external lubricating oil forced circulation pump and sprays lubricating oil onto the friction pair through a direct injection pipe. On the one hand, it plays a lubricating role, and on the other hand, it has a certain cooling effect. This method is generally used on heavy-duty machinery; oil mist lubrication generally requires the use of a condensation nozzle because during the process of oil mist lubrication, the lubricating oil is in a mist state, and misty lubricating oil has no lubricating effect. It is necessary to restore the misty lubricating oil back to liquid lubricating oil through a condensation nozzle, but this nozzle must be accurately designed and selected according to the oil consumption at the lubrication point; oil-gas lubrication requires a corresponding nozzle because oil-gas lubrication requires special structural design at the lubrication point. The oil injection volume is quantitatively supplied by the main engine, and the role of the nozzle is to connect and conduct compressed air to the lubrication point for necessary cooling, so the structure is relatively simple.

[0003] However, it is impossible to achieve good lubrication effects for lubrication pairs with complex structures using simple lubricating oil layout facilities. Especially for equipment with complex internal transmission structures such as robotic arms, which are composed of various bearings, shafts, and planetary gear systems inside, it is necessary to ensure that each transmission part can be effectively lubricated during operation. At present, equipment with such complex internal structures usually adopts oil immersion lubrication. Although it can lubricate each transmission part, it has disadvantages such as easy leakage, easy heating, and high operating noise. In addition, there is also a method of using oil mist lubrication to lubricate such equipment with complex internal structures, but it is difficult for misty lubricating oil to quickly settle on the surface of transmission parts to form an oil film, resulting in poor lubrication effects.

[0004] Micro-bead oil lubrication is a brand-new mechanical lubrication method. Its principle is to use compressed air as a power source to convert liquid lubricating oil into spherical liquid lubricating oil with a diameter of 30 - 70 μm in a special reactor. The formed micro-bead oil is in a semi-suspended state, and its flow characteristics are between those of gas and liquid. It can be introduced into the transmission cavity of the equipment to contact the surface of the transmission parts and quickly settle to form an oil film, thereby achieving the lubrication effect. However, the volume density of micro-bead lubricating oil is smaller than that of oil mist lubrication, making it difficult to quickly and comprehensively contact the lubrication pair with a complex internal structure, and then settle to form an oil film for lubrication. Therefore, there is an urgent need to design a dumbbell-shaped micro-bead oil dispenser that can quickly and comprehensively contact the micro-bead oil with the lubrication pair with a complex structure. Summary of the Invention

[0005] The purpose of the present utility model is to provide a dumbbell-shaped micro-bead oil dispenser to solve the deficiencies existing in the lubrication of lubricating pairs with complex internal structures by using the micro-bead oil lubrication method.

[0018] Embodiment 1 discloses a dumbbell-shaped microbead oil dispenser. Referring to the attached Figure 1 and the attached Figure 2 drawings, it includes a handle 1, a head 2, and an oil quantity adjustment cone 3. The head 2 is composed of a middle cylinder 201 and two end frustum cones 202, and the handle 1 is integrally formed with one side of the frustum cone 202, so that the handle 1 and the head 2 form a main body similar to a dumbbell shape. A microbead oil channel 4 is opened on the end surface of the handle 1 towards the inside of the head 2, so that the suspended microbead oil can enter the inside of the head 2 through the microbead oil channel 4.

[0019] On the outer circumferential surface of the middle cylinder 201, a number of groups of radially arranged spray holes 203 are circumferentially and uniformly provided. On the outer conical surfaces of the two frustum-shaped bodies 202 at both ends, a number of groups of first radiation spray holes 204 with an inclination angle of α° and a number of second radiation spray holes 205 with an inclination angle of β° are circumferentially and uniformly provided respectively. Moreover, the radial spray holes 203, the first radiation spray holes 204, and the second radiation spray holes 205 are all much larger than the particle size of the microbead oil, and are preferably set between 1.5 and 2.5 mm.

In addition, the inclination angles of the first radiation spray holes 204 and the second radiation spray holes 205 are calculated and determined according to the positions of the points to be lubricated, and corresponding adjustments can be made.

[0020] On the end face of the frustum-shaped body 202 on the side away from the tool handle 1, a threaded hole 206 is provided, and an external thread adapted to the threaded hole 206 is provided on the outer circumferential surface of the oil quantity adjustment cone 3, so that the oil quantity adjustment cone 3 can be hermetically screwed with the threaded hole 206.
