Description

Technical Field

[0001] The present invention belongs to the field of bearing seat technical equipment, and in particular relates to a bearing seat cooling circulation device based on self-adaptive adjustment of spindle speed. Background Art

[0002] As a component that connects and supports bearings, the design of the bearing seat has a certain impact on the normal service life of the bearing. For example, in rolling mills, bearing overheating and mill vibration are the main causes of premature bearing damage. Mill vibration is determined by the rolling mill system. The causes of bearing overheating can be divided into the influence of bearing seat lubrication measures and cooling measures.

[0003] From the perspective of lubrication, in the production of high-speed rolling mills, the bearing seat is the component for installing bearings and bearing the mill load. Usually, a lubricating oil hole is opened on the bearing seat, and the bearing is lubricated by oil and gas lubrication. The roller is a component that is in direct contact with the rolled piece. A large amount of heat is generated during the rolling process, so cooling water spraying is often used to cool the roller. The previous bearing seat was relatively simple in structure. Although it was easy to manufacture and install, the waterproof effect was not ideal. Cooling water could easily enter the bearing seat cavity to reduce the viscosity of the lubricating oil, causing dry friction between metals, resulting in surface stress and surface damage.

[0004] From a cooling perspective, the function of rolling mill bearings is to support the rotation of the rolls, withstand the rolling forces transmitted by the rolls, and maintain the rolls' correct position in the mill frame. During high-speed operation of the rolling mill, the inner and outer rings of the bearings, as well as the rollers, are in relative motion. This rolling force generates a significant amount of heat. Conventional bearing seats have lubricating oil holes, which not only provide lubrication but also absorb heat from the bearings.

[0005] Currently, Chinese patent publication CN 102644666 A discloses a bearing seat device with water circulation cooling. The device comprises a bearing housing, a lubricating oil cavity within the bearing housing, an oil inlet on one side of the bearing housing, and a water cooling assembly disposed around the lubricating oil cavity. The water cooling assembly comprises a water-cooling jacket plate, and a water-cooling space is provided between the water-cooling jacket plate and the bearing housing. This effectively removes the substantial heat generated by the rotating shaft during operation, ensuring stable operation of the equipment. However, in actual rolling mill operation, the cooling water reduces lubrication effectiveness, and heat in the bearing accumulates continuously over time, ultimately affecting the bearing lifespan. Summary of the Invention

[0046] like Figure 4 As shown, the cooling magnetic energy assembly 3 includes a magnetic wheel 301, a magnetic wheel holder 302, a permanent magnet 303, a first push rod 304, a second push rod 305, a first fixed ring 306, a movable push rod 307, a travel spring 308, an adjusting push rod 309, a rectangular shell 310, and an end cover 311. The magnetic wheel holder 302 is sleeved on the outer ring of the magnetic wheel 301, and the permanent magnet 303 passes through the magnetic wheel holder 302 and is threadedly connected to the magnetic wheel 301.

[0047] When the roller rotates, the magnetic wheel 301 installed on the inner ring 201 of the shoulder sleeve rotates synchronously, and the permanent magnet 303 on the magnetic wheel 301 will repel or attract the permanent magnet 303 in the rectangular shell 310, causing the permanent magnet 303 in the rectangular shell 310 to move up and down repeatedly, squeezing the stroke spring 308 and driving the moving push rod 307 between the first push rod 304 and the second push rod 305 to move up and down repeatedly; the other end of the stroke spring 308 is adjusted.

The water supply cylinder 401 is cylindrical, and a rectangular window is provided on the side of the water supply cylinder 401. A water supply inlet 412 is provided at the bottom of the water supply cylinder 401. Water supply outlets 411 are provided on both sides of the bottom of the water supply cylinder 401.

[0054] When the shaft rotates, the magnetic wheel 301 installed on the inner ring 201 of the shoulder sleeve rotates synchronously, and the permanent magnet 303 on the magnetic wheel 301 will repel or attract the permanent magnet 303 in the rectangular shell 310, causing the permanent magnet 303 in the rectangular shell 310 to move up and down repeatedly, squeezing the stroke spring 308 and driving the moving push rod 307 between the first push rod 304 and the second push rod 305 to move up and down repeatedly; the adjusting push rod 309 at the other end of the stroke spring 308 is provided with a threaded portion that contacts the end cover 311, and the initial compression length of the stroke spring 308 can be adjusted by rotating the adjusting push rod 309, thereby adjusting the single stroke length of the moving push rod 307.

[0055] When the push rod 307 moves up and down repeatedly, the push rod 307 drives the water supply piston 402 to move up and down repeatedly in the water supply cylinder 401; when the water supply piston 402 moves downward, the thread in the large cylindrical groove of the water supply piston 402 will engage with the card needle 410 installed on the ejector seat 406, so that the ejector seat 406 enters the large cylindrical groove of the water supply cylinder 401. When the water supply piston 402 moves upward, the ejector seat 406 moves upward with the water supply piston 402, and the rubber needle 407 no longer blocks the water supply inlet 412. The water supply cylinder 401 becomes a low-pressure state to extract cooling water from the cooling box 6. During the upward movement of the water supply piston 402, the impact seat 408 on the ejector seat 406 will gradually approach the ejector seat 409, and finally the two will offset each other. During the subsequent upward movement of the water supply piston 402, the ejector seat 406 will be pushed out of the water supply piston 402, and the rubber needle 407 will block the water supply inlet 412 again, and the water supply piston 402 will move downward again, squeezing the cooling water into the cooling guide assembly 5 through the water supply outlet 411, completing one water supply.

[0056] The cooling water then enters the box body 501 through the guide water inlet 505 and flows into the rubber seat 502. The cooling water will push the arrow of the guide push rod 503, squeeze the return spring 504 on the arrow tail of the guide push rod 503, and expose the through hole on the guide push rod 503. The cooling water flows from the arrow to the arrow tail of the guide push rod 503 through the through hole, and enters the cooling tank 9 through the cooling hose 10 connected to the guide water outlet 506. After absorbing the heat of the bearing, it enters the cooling and heat dissipation component 8, transfers the heat to the heat dissipation scales 801, and then enters the filter layer 702 for filtration through the filter water inlet 703 of the cooling filter component 7. Finally, it flows through the filter outlet 704 and the water tank inlet 602 in sequence to enter the cooling box body 6 to complete a cooling cycle.

[0057] The above-mentioned embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
