Description

Technical Field

[0001] This utility model relates to the field of bearing heat dissipation structure technology, specifically a novel heat dissipation structure for strip rolling mill roll bearings. Background Technology

[0002] In the production and processing of aluminum foil strip, the heat generated during rolling will accumulate on the rolls. Further accumulation of heat will cause the roll bearings to overheat. Overheating of the bearings will cause the bearings to stop rotating, thus slowing down production. In order to reduce the accumulation of heat in the bearings, it is necessary to modify the structure of the roll bearing housing and optimize the cooling capacity.

[0003] Chinese Utility Model Patent Publication No. CN222315714U discloses a bearing heat dissipation ring and a bearing housing, relating to the field of bearing technology. The bearing heat dissipation ring has an inner contact end face and an outer contact end face at both ends. The ring has a mounting hole connecting the inner and outer contact end faces. A first annular groove is formed on the outer contact end face. A heat dissipation hole is provided on the side wall of the first annular groove, connecting the first annular groove and the outer peripheral wall of the bearing heat dissipation ring. In this invention, the air velocity in the first annular groove increases due to the rotation of the bearing heat dissipation ring. According to Bernoulli's principle, the increased velocity leads to a decrease in pressure within the first annular groove. At this time, the air pressure outside the groove is relatively high, so air is pushed into the groove with lower pressure. Due to the rotation of the bearing heat dissipation ring, the air in the first annular groove also generates centrifugal force and is discharged along the heat dissipation hole on the outer wall of the first annular groove, simultaneously carrying away the high temperature inside the bearing housing, effectively reducing the temperature of the bearing housing.

[0004] While the aforementioned bearing heat dissipation rings can assist in heat dissipation during use, the efficiency of heat transfer via air is relatively low. Consequently, the heat dissipation efficiency is low when the bearing operates at high speeds or for extended periods. Heat accumulation can lead to increased wear on bearing materials, reducing bearing lifespan. Furthermore, reduced rotational speed will decrease production efficiency. Therefore, we propose a novel heat dissipation structure for strip rolling mill roll bearings. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a novel heat dissipation structure for strip rolling mill roll bearings, thereby solving the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel heat dissipation structure for strip rolling roll bearings, comprising a fixing component, a cooling component, and a filtering component. The fixing component includes a bearing housing, a connecting bearing is fixedly mounted on the side wall of the bearing housing, and a rotating roller is fixedly mounted on the inner wall of the connecting bearing. The cooling assembly includes an inlet pipe, and the outer wall of the bearing housing is provided with a collecting pipe and a diverting pipe. The outer walls of the collecting pipe and the diverting pipe are both connected by connecting pipes. The inlet pipe is provided with an outlet pipe on the side near the connecting bearing. A liquid guiding groove is provided in the middle of the bearing housing, and a diverting groove is provided on the inner wall of the liquid guiding groove.

[0007] Through the above technical solution, by setting up a fixed component, a cooling component, an inlet pipe, an outlet pipe, a connecting pipe, and a collecting pipe structure, the device allows coolant to be introduced into the connecting bearing through the inlet pipe when the roller rotates due to the operation of the component during operation. This allows the coolant to flow in the guide groove and the distribution groove, thereby increasing the contact area between the coolant and the connecting bearing, ensuring that the heat generated during component friction is quickly carried away, and thus improving the heat dissipation efficiency of the roller bearing.

[0008] Preferably, the filter assembly includes a housing, an inner wall of which has an installation groove, a round rod fixedly mounted on the inner wall of the installation groove, a return spring sleeved on the outer wall of the round rod, a sliding plate abutting the end of the return spring away from the bottom of the outlet pipe, a crossbar fixedly mounted on the outer wall of the sliding plate, a filter element fixedly mounted on the end of the crossbar away from the sliding plate, and an infusion pipe provided on the outer wall of the housing.

[0009] Through the above technical solution, the filter components, housing, and mounting groove structure enable the structure to filter the coolant flowing into the inlet pipe during operation using the filter element. This prevents the coolant from carrying metal debris from the components and clogging the channels, thus ensuring the continuous operation of the heat dissipation structure, reducing maintenance frequency, and improving the practicality of the structure.

[0010] Preferably, the inlet of the slide plate is connected to the interior of the diversion pipe, and the outlet of the slide plate is connected to the interior of the liquid collection pipe.

[0011] Through the above technical solution, the structure with the set diversion pipe and slide plate allows the coolant that carries away heat to be discharged through the liquid collection pipe during the process of assisting the connection bearing in heat dissipation. This makes it convenient for users to recycle the discharged coolant, reduce coolant waste, and further improve the practicality of the structure.

[0012] Preferably, the flow divider is arc-shaped, and the arc portion of the flow divider is close to the inner diameter of the connecting bearing.

[0013] Through the above technical solution, the diversion channel structure is designed to bring the coolant closer to the inner diameter of the connecting bearing, thereby reducing the distance between the inner diameter of the connecting bearing and the coolant flow channel. This ensures that the coolant can fully absorb and carry away heat, further improving the heat dissipation effect of the structure.

[0014] Preferably, the number of the diversion channels is several, and the several diversion channels are evenly distributed along the inner wall of the liquid guiding channel.

[0015] Through the above technical solution, by setting up several diversion channels, the structure can divert the coolant during operation, thereby increasing the contact area between the coolant and the connecting bearing, and thus ensuring the auxiliary heat dissipation effect of the structure on the connecting bearing.

[0016] Preferably, the outer wall of the outer shell is provided with a connection hole, the inner wall of the connection hole is provided with a round tube, and the end of the round tube is connected to the inside of the liquid inlet pipe.

[0017] Through the above technical solution, the connection hole and the round tube structure are designed so that the outer shell can be connected to the liquid inlet pipe during use. This allows the coolant to enter the liquid inlet pipe, the liquid guide groove, and the distribution groove, thereby enabling the coolant to flow and complete the heat dissipation effect of the auxiliary connecting bearing, thus ensuring the normal operation of the structure.

[0018] Preferably, the end of the infusion tube away from the outer shell is equipped with an infusion pump, and the inner wall of the mounting groove is slidably connected to the outer wall of the slide plate.

[0019] Through the above technical solution, the structure, including the outer shell, infusion tube, and sliding plate, allows the coolant to be filtered by the filter element inside the shell after installation. This separates debris from the coolant, preventing debris from entering the structure and causing blockage of the flow channels. During maintenance, the user can remove the outer shell and pull the filter element out, making it easier to clean impurities and debris from the filter element, thus improving the user's maintenance efficiency.

[0020] Compared with the prior art, this utility model provides a novel heat dissipation structure for strip rolling roll bearings, which has the following beneficial effects: 1. This novel strip rolling mill roll bearing heat dissipation structure, through the setting of fixed components, bearing housing, connecting bearing, liquid inlet pipe, liquid outlet pipe, connecting pipe, liquid collection pipe, liquid guide groove, and diversion groove, enables the structure to guide the coolant into the liquid guide groove through the liquid inlet pipe during operation, and then allow the coolant to flow through multiple channels through the diversion groove. This improves the heat dissipation efficiency by liquid cooling and increasing the contact area between the coolant and heat, thereby improving the auxiliary heat dissipation effect of the structure on the connecting bearing.

[0021] 2. This novel strip rolling mill roll bearing heat dissipation structure, through the setting of filter components, crossbars, filter elements, liquid delivery pipes, and crossbar structure, enables the structure to separate impurities and debris entrained in the coolant during use, thereby preventing blockage of the flow channels. During maintenance, the user only needs to remove the outer shell and pull out the filter element for cleaning and maintenance, thus improving the practicality of the structure and the user's maintenance efficiency.

[0026] The advantage is that, through the structure of the fixed component 1, cooling component 2, liquid inlet pipe 201, liquid outlet pipe 202, connecting pipe 203, and liquid collection pipe 204, when the connecting bearing 102 rotates due to the operation of the component, the coolant can be introduced into the connecting bearing 102 through the liquid inlet pipe 201, so that the coolant flows in the liquid guide groove 205 and the diversion groove 206, thereby increasing the contact area between the coolant and the connecting bearing 102, ensuring that the heat generated during component friction is quickly carried away, and thus improving the heat dissipation efficiency of the roller bearing.

[0027] Specifically: the filter assembly 3 includes a housing 301, the inner wall of the housing 301 is provided with an installation groove 302, the inner wall of the installation groove 302 is fixedly fitted with a round rod 303, the outer wall of the round rod 303 is sleeved with a return spring 304, the end of the return spring 304 away from the bottom of the liquid outlet pipe 202 abuts against a sliding plate 305, the outer wall of the sliding plate 305 is fixedly fitted with a crossbar 306, the end of the crossbar 306 away from the sliding plate 305 is fixedly fitted with a filter element 307, and the outer wall of the housing 301 is provided with an infusion pipe 308.

[0028] The advantage is that, through the structure of the filter component 3, housing 301, and mounting groove 302, the structure uses the filter element 307 to filter the coolant flowing into the inlet pipe 201 during operation, thereby preventing the coolant from carrying metal debris from the components and clogging the channels, thus ensuring the continuous operation of the heat dissipation structure, reducing maintenance frequency, and improving the practicality of the structure.

[0029] Specifically: the inlet of the slide plate 305 is connected to the inside of the diversion pipe 207, and the outlet of the slide plate 305 is connected to the inside of the liquid collection pipe 204.

[0030] The advantage is that, through the structure of the diversion pipe 207 and the slide plate 305, the structure can use the liquid collection pipe 204 to discharge the coolant that carries away heat during the process of assisting the cooling of the connecting bearing 102. This makes it convenient for users to recycle the discharged coolant, reduce the waste of coolant, and further improve the practicality of the structure.

[0031] Specifically, the flow divider 206 is designed to be arc-shaped, and the arc portion of the flow divider 206 is close to the inner diameter of the connecting bearing 102.

[0032] The advantage is that by setting the diversion groove 206 structure, the diversion groove 206 of a specific shape allows the coolant to get closer to the inner diameter of the connecting bearing 102, thereby reducing the distance between the inner diameter of the connecting bearing 102 and the coolant flow channel, ensuring that the coolant can fully absorb heat and carry it away, further improving the heat dissipation effect of the structure.

[0033] Specifically: there are several flow dividers 206, and all of them are evenly distributed along the inner wall of the liquid guiding channel 205.

[0034] The advantage is that by setting up a number of diversion channels 206, the structure can divert the coolant during operation, thereby increasing the contact area between the coolant and the connecting bearing 102, and thus ensuring the auxiliary heat dissipation effect of the structure on the connecting bearing 102.

[0035] Specifically: the outer wall of the outer casing 301 is provided with a connection hole, the inner wall of the connection hole is provided with a round tube, and the end of the round tube is connected to the inside of the liquid inlet pipe 201.

[0037] Specifically: the end of the infusion tube 308 away from the outer casing 301 is equipped with an infusion pump, and the inner wall of the mounting groove 302 is slidably connected to the outer wall of the slide plate 305.

[0038] The advantage is that, through the structure of the housing 301, the infusion tube 308, and the slide plate 305, after installation, the filter element 307 in the housing 301 filters the coolant, thereby separating debris from the coolant and preventing debris from entering the structure and causing blockage of the flow channel. During maintenance, the user can remove the housing 301 and pull the filter element 307 out of the housing 301, making it easy for the user to clean the impurities and debris on the filter element 307, thus improving the user's maintenance efficiency of the structure.

[0039] Working principle: After the user completes the installation of the structure, the coolant is pumped into the housing 301. The filter element 307 separates debris from the coolant, preventing debris from entering the coolant channels and causing blockages. This ensures the continuous operation of the heat dissipation structure. After the coolant enters the guide groove 205 and the distribution groove 206, the arc-shaped distribution grooves 206 increase the contact area between the connecting bearing 102 and the coolant, thereby improving the efficiency of the coolant in absorbing heat and enhancing the auxiliary heat dissipation efficiency of the connecting bearing 102. During maintenance, the user only needs to remove the housing 301 and pull out the filter element 307 for cleaning, thus improving the practicality of the structure and the user's maintenance efficiency.
