Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of atomizer bearing lubrication, in particular to a deep lubrication atomization structure. Background Art
[0002] The double bearing structure consisting of an upper bearing and a lower bearing generally refers to a configuration in which two bearings are installed on the same shaft, one above and one below, to jointly bear axial and radial loads and improve the stability and rigidity of the system. This layout can select different bearing types according to application requirements, such as deep groove ball bearings, cylindrical roller bearings, angular contact ball bearings, etc. In practical applications, such as conveyor rollers, motor shaft supports, machine tool spindles, etc., the double bearing structure can effectively reduce the deflection of the shaft, improve rotation accuracy and running stability. In order to ensure the correct installation and operation of the bearing, appropriate preload is usually required to eliminate the clearance, and spacers or sleeves may be required to maintain the correct axial and radial position. In the field of centrifugal atomizers, a double bearing structure is also used, but the traditional lubrication method is splash lubrication, that is, the lubricating oil drips on the upper gear, and the lubricating oil is splashed onto the bearing by gravity and centrifugal action. The lubrication effect of the lower bearing located below is poor. The surface of the upper bearing is prone to form a flat covering oil film during operation, which prevents the lubricating oil from falling, resulting in a lack of lubrication of the lower bearing. When bearings lack lubrication, metal surfaces come into direct contact, increasing friction and potentially causing bearing overheating and wear. Due to increased friction, the heat generated by the bearing during operation will also increase, which may lead to excessive temperatures, further accelerating material fatigue and damage. Bearings that lack lubrication will produce abnormal noise and vibration during operation, which is caused by irregular contact and wear between metal surfaces. Long-term lack of lubrication will greatly shorten the service life of the bearing and may require frequent replacement, increasing maintenance costs and downtime. The performance of the bearing directly affects the efficiency and stability of the entire mechanical system. Lack of lubrication will lead to a decline in overall performance and affect production efficiency. Utility Model Content
[0003] Technical problems to be solved by utility models
[0004] In view of the technical problem of how to optimize the lubrication of the lower bearing of the double bearings, the utility model provides a deep lubrication atomization structure, which can completely lubricate both the upper bearing and the lower bearing.
[0005] Technical Solution
[0006] In order to solve the above problems, the technical solution provided by the utility model is:
[0007] A deep lubrication atomization structure comprises a supporting flange fixed in an atomizer housing, a through hole and an oil inlet channel being provided in the center, the oil inlet channel being connected to an oil supply mechanism; a bearing sleeve being provided with an oil inlet hole connected to the oil inlet channel; a bearing comprising an upper bearing and a lower bearing and being installed in the bearing sleeve, a gap being provided between the upper bearing and the lower bearing, the gap being aligned with the oil inlet hole; a pressure cover being located above the upper bearing, the top of the pressure cover being provided with an inwardly inclined slope, the inner edge of the top of the pressure cover being directly opposite to the upper bearing.
[0008] Comprehensive lubrication: Through the precisely designed oil inlet holes and the gaps between the bearings, the lubricating oil can be evenly distributed on the contact surfaces of the upper and lower bearings, achieving comprehensive lubrication, effectively reducing friction and wear, and increasing the service life of the bearings.
[0009] Efficient atomization: Using the pressure provided by the oil supply mechanism, the lubricating oil is atomized into fine particles before entering the bearing, which increases the contact area between the lubricating oil and the bearing surface, improves the lubrication efficiency, and reduces the amount of lubricating oil used, which is more economical and environmentally friendly.
[0010] Adaptive adjustment: The slope design on the gland helps to automatically adjust the distribution of the lubricating oil, ensuring that the lubricating oil is evenly covered on the bearing evenly under different working conditions, improving the stability and reliability of the system.
[0011] Reduced maintenance costs: By improving lubrication efficiency and extending bearing life, the maintenance frequency and cost of equipment are reduced, while also reducing the risk of production interruptions due to bearing failures.
[0012] Enhanced heat dissipation: Atomized lubricating oil not only cools the bearing, but also takes away the heat generated by friction, which helps to reduce the operating temperature of the bearing and further improve its performance and durability.
[0013] Simplified structural design: The structure is compact and achieves efficient lubrication through a simple combination of components, which is easy to install and maintain, reducing complexity and potential failure points.
[0014] Optionally, a step is provided on the upper portion of the bearing sleeve, and the bearing sleeve and the support flange are axially limited.
[0015] The presence of the step enables the bearing sleeve to be accurately positioned in the axial direction, ensuring that its relative position with the support flange remains fixed. When the bearing is subjected to axial force, the step can serve as a support point to help disperse and carry this part of the load, avoid unnecessary displacement of the bearing sleeve, thereby protecting the bearing from additional stress and extending its service life. The design of the step simplifies the assembly process of the bearing assembly. The step increases the contact area between the bearing sleeve and the support flange, helps to improve the rigidity of the entire structure, reduces deformation under high load or vibration conditions, and ensures the stable operation of the mechanical system. When the bearing assembly needs to be maintained or replaced, the step design allows the bearing sleeve to be easily removed from the support flange, facilitating necessary inspections and adjustments, reducing the difficulty and cost of maintenance.
[0016] Optionally, a step is provided at the lower portion of the bearing sleeve, and the bearing sleeve and the lower bearing are axially limited.
[0017] Same as above.
[0018] As an option, the gland is axially limited at the top by the upper bearing.
[0019] The gland prevents the upper bearing from detaching upward.
[0020] Optionally, a spacer ring is provided between the inner rings of the upper bearing and the lower bearing.
[0021] The spacer is used to provide a gap between the upper bearing and the lower bearing to facilitate the entry of lubricating oil and lubricate the upper bearing and the lower bearing, thereby improving the lubrication effect.
[0022] Optionally, the oil inlet passage is connected to the oil supply mechanism via an oil supply pipe.
[0023] The oil supply pipe is a bridge connecting the oil inlet channel and the oil supply mechanism, which can ensure that the lubricating oil is accurately delivered from the oil supply mechanism to the bearing or other parts that need lubrication. The length and curvature of the oil supply pipe can be adjusted according to the actual installation space and layout, making the lubrication system design more flexible and adaptable to various complex mechanical structures.
[0024] Optionally, a nut is provided on the oil supply pipe, and the nut is fastened to the supporting flange.
[0025] The fastening connection between the nut and the support flange can ensure that the oil supply pipe is firmly fixed in the predetermined position, avoiding loosening or displacement under mechanical vibration or external impact, and ensuring the stability and reliability of the oil supply system. The use of nuts makes the installation and removal of the oil supply pipe simple and quick, and is convenient for regular inspection, cleaning or replacement of the oil supply pipe, reducing the difficulty and cost of maintenance, and also facilitating fault diagnosis and rapid repair, reducing equipment downtime.
[0026] Optionally, a gear is provided above the pressure cover, and the diameter of the top of the pressure cover is larger than the diameter of the gear.
[0027] The gland is larger and can catch the lubricating oil of the gear, making it less likely for the lubricating oil to leak.

[0029] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:
[0030] The technical solution provided by the utility model provides an oil inlet hole for the gap between the upper bearing and the lower bearing, so that the lubricating oil can be evenly distributed on the contact surface of the upper bearing and the lower bearing, thereby achieving comprehensive lubrication, effectively reducing friction and wear, and increasing the service life of the bearing.
