Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a polyurethane ball joint cooling device with good heat dissipation. Background Technology

[0002] Polyurethane ball joints are widely used in various fields due to their excellent wear resistance, oil resistance, and shock absorption performance in numerous industrial equipment and mechanical systems. For example, in automotive suspension systems, polyurethane ball joints can be used to connect different components, ensuring vehicle stability and comfort; in aerospace equipment, polyurethane ball joints are also used to achieve flexible rotation and connection between components.

[0003] Existing polyurethane ball joint cooling devices mainly focus on a single cooling method, such as relying solely on air cooling or liquid cooling circulation. This makes it impossible to flexibly adjust the cooling method according to the actual working state and heat generation of the ball joint. Under some complex working conditions, a single cooling method may not be able to dissipate the heat generated by the ball joint in a timely and effective manner, causing the ball joint temperature to rise continuously, which in turn affects the performance and stability of the entire equipment. Therefore, it is necessary to propose a polyurethane ball joint cooling device with good heat dissipation to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a polyurethane ball joint cooling device with good heat dissipation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A polyurethane ball joint cooling device with good heat dissipation includes a support base and an end cap. The end cap is installed on the upper end of the support base by multiple sets of screws. The inner walls of both the support base and the end cap are arc-shaped. A ball joint is rotatably connected to both the support base and the end cap. A cooling box is provided outside the support base. Two sets of connecting pipes and two sets of connecting pipes are provided on the outer wall of the cooling box. A cooling cavity is opened inside the support base. One-way valves are installed in both sets of connecting pipes and are connected to the cooling cavity. Spray holes are opened on the inner wall of the end cap. One set of connecting pipes is connected to multiple sets of spray holes. Two device cavities are opened inside the cooling box. Heat dissipation fins are provided at the lower end of the cooling box. Two sets of pistons are movably connected in the device cavities. Coolant is injected into both device cavities. A drive assembly for driving the pistons is installed in the device cavities.

[0007] Preferably, the drive assembly includes a reciprocating screw rotatably connected to two sets of device cavities. Each threaded section of the reciprocating screw is threaded with a screw sleeve. A connecting rod is fixedly connected to the outer wall of the screw sleeve, and the ends of the connecting rods are respectively fixedly connected to their adjacent pistons.

[0008] Preferably, each end of the reciprocating lead screw is fixedly connected to a limit block, and the radius of the limit block is larger than that of the reciprocating lead screw.

[0009] Preferably, a side plate is fixedly connected to the outer wall of the cooling box, and two sets of gears are rotatably connected to the outer wall of the cooling box, with the two sets of gears meshing with each other.

[0010] Preferably, the two sets of gears are coaxially and fixedly connected to the two sets of reciprocating lead screws, and the other set of connecting pipes is connected to an external container containing coolant.

[0011] Preferably, a servo motor is fixedly connected to the outer wall of the side plate, and the output shaft of the servo motor is coaxially and fixedly connected to its adjacent gear.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model achieves a dual cooling mode combining spray cooling and circulating liquid cooling by setting up spray holes and a cooling chamber. The coolant is sprayed directly onto the outer wall of the ball joint from the spray holes through the first connecting pipe, while another part of the coolant flows into the cooling chamber in one direction through the second connecting pipe, so as to dissipate heat from the ball joint in all directions. Compared with the traditional single cooling method, it can remove the heat generated by the ball joint during operation more quickly and efficiently, effectively avoid the ball joint from degrading due to high temperature, and improve the cooling effect.

[0014] 2. This utility model uses a servo motor to drive two sets of meshing gears, which in turn drive a reciprocating screw to rotate, thereby causing the piston to reciprocate within the device cavity. By controlling the speed and direction of the servo motor, the circulation speed and flow rate of the coolant can be flexibly adjusted, allowing for flexible cooling based on the actual heating of the ball joint.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A polyurethane ball joint cooling device with good heat dissipation includes a support base 1 and an end cap 2. The end cap 2 is installed on the upper end of the support base 1 by multiple sets of screws. The inner walls of both the support base 1 and the end cap 2 are arc-shaped. A ball head 3 is rotatably connected to both the support base 1 and the end cap 2. A cooling box 4 is provided outside the support base 1. Two sets of connecting pipes 6 and two sets of connecting pipes 7 are provided on the outer wall of the cooling box 4. A cooling cavity 9 is opened inside the support base 1. One-way valves are installed in both sets of connecting pipes 7 and are connected to the cooling cavity 9. Spray holes 10 are opened on the inner wall of the end cap 2. One set of connecting pipes 6 is connected to multiple sets of spray holes 10. Two device cavities 11 are opened inside the cooling box 4. Heat dissipation fins are provided at the lower end of the cooling box 4. Two sets of pistons 15 are movably connected in the device cavity 11. Coolant is injected into both device cavities 11. A drive assembly for driving the pistons 15 is installed in the device cavity 11.

[0022] Furthermore, through the cooperation of the spray hole 10 and the cooling chamber 9, dual cooling of the bearing seat 1, end cover 2 and ball head 3 by the coolant is achieved. Compared with the existing single cooling method, it can more efficiently remove the heat generated when the ball joint is working, and avoid the ball joint from degrading due to high temperature.

[0023] The drive assembly includes a reciprocating screw 12 rotatably connected in two sets of device cavities 11. Each threaded section of the reciprocating screw 12 is threaded with a screw sleeve 13. A connecting rod 16 is fixedly connected to the outer wall of the screw sleeve 13, and the ends of the connecting rod 16 are respectively fixedly connected to their adjacent pistons 15.

[0024] Furthermore, the rotation of the reciprocating screw 12 drives the piston 15 to reciprocate within the device cavity 11, actively controlling the circulation of the coolant. The flow rate of the coolant can be flexibly adjusted according to the actual working state and heat generation of the ball joint, enabling the cooling system to better adapt to different working conditions and improve the cooling effect. It should be noted that the outer wall of the screw sleeve 13 is in close contact with the inner wall of the device cavity 11. When the reciprocating screw 12 drives the screw sleeve 13 to rotate, the screw sleeve 13 can only move horizontally along the axis of the reciprocating screw 12.

[0025] Each end of the reciprocating lead screw 12 is fixedly connected to a limit block 14, the radius of the limit block 14 is larger than the radius of the reciprocating lead screw 12. A side plate 5 is fixedly connected to the outer wall of the cooling box 4. Two sets of gears 8 are rotatably connected to the outer wall of the cooling box 4. The two sets of gears 8 mesh with each other. The two sets of gears 8 are coaxially fixedly connected to the two sets of reciprocating lead screws 12 respectively. Another set of connecting pipes 6 is connected to an external container containing coolant.

[0026] Furthermore, the two sets of device cavities 11 respectively serve the purposes of spraying and heat exchange. The spray holes 10 allow the coolant to be sprayed directly onto the outer wall of the ball head 3, while the cooling cavity 9 further dissipates heat from the ball head 3. The heat dissipation fins effectively dissipate heat from the coolant inside the device cavity 11.

[0027] A servo motor 17 is fixedly connected to the outer wall of the side plate 5, and the output shaft of the servo motor 17 is coaxially fixedly connected to the adjacent gear 8.

[0028] In this utility model, when the device is used, the support seat 1 and the end cover 2 are securely connected by screws, together accommodating the ball head 3 to achieve flexible rotation.

[0029] When the polyurethane ball joint generates heat during equipment operation, the operator activates the servo motor 17 on the outer wall of the side plate 5. The output shaft of the servo motor 17 drives the gear 8 to rotate, and the power is synchronously transmitted to the two sets of reciprocating screws 12 through two sets of meshing gears 8. When the reciprocating screw 12 rotates, the threaded screw sleeve 13 moves linearly back and forth along its thread, which drives the piston 15 to move back and forth in the device cavity 11 through the connecting rod 16, driving the coolant to start circulating. Under pressure, the coolant is transported through a set of connecting pipes 1-6 to the spray holes 10 on the inner wall of the end cover 2, directly spraying onto the outer wall of the ball head 3, carrying away a large amount of heat; at the same time, another part of the coolant flows into the cooling cavity 9 in the bearing seat 1 through the one-way valve of the connecting pipe 2-7, further dissipating heat from the entire ball joint. The heat dissipation fins at the lower end of the cooling box 4 continuously dissipate heat from the coolant in the device cavity 11. When the piston 15 moves inward, another set of connecting pipes 6 draws the coolant from the external container into the device cavity 11 to replenish the coolant in time and ensure continuous circulation.

[0030] Throughout the cooling process, components such as the cooling box 4, connecting pipe, device cavity 11, and piston 15 work together to quickly remove the heat generated by the polyurethane ball joint through a dual cooling method of spraying and circulating liquid cooling. Compared with the traditional single cooling method, this device can flexibly adjust the cooling liquid circulation speed and flow rate according to the actual heat generation of the ball joint through the servo motor 17 to achieve precise and efficient heat dissipation, avoid the ball joint's performance degradation due to high temperature, and effectively improve the stability and reliability of equipment operation.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
