Description

Technical Field

[0001] The utility model relates to a radial bearing seat of a dynamic pressure air bearing, in particular to a radial bearing seat of a dynamic pressure air bearing with a temperature early warning function. Background Art

[0002] As a new generation of air supply and pressure fans for industries such as sewage treatment, aquaculture, and papermaking, air-floating fans offer advantages not found in traditional fans, such as energy efficiency, stability, and low noise. However, due to the high speeds of air-floating centrifugal fans, the air bearings are relatively weak, and any operational issues can lead to overload and burnout of the air bearings. A hydrodynamic air bearing is a sliding bearing lubricated with air. It operates by utilizing the hydrodynamic air film formed between the high-speed rotating rotor and the bearing to support and separate the contact surface between the shaft and bearing, thereby reducing friction and wear. The bearing seat is used to secure the hydrodynamic air bearing.

[0003] Common hydrodynamic air bearing radial bearing seats are unable to monitor the bearing temperature inside during use, often leading to damage due to excessive temperature. Furthermore, it is inconvenient to install and secure the bearings. Furthermore, during use, the high-speed rotation of the bearings can cause the connections to loosen, leading to unstable operation.

[0004] Therefore, the above-mentioned dynamic pressure air bearing radial bearing seat does not have a temperature control component, and the problem of the bearing becoming loose after long-term operation needs to be solved urgently to improve the use scenario of the dynamic pressure air bearing radial bearing seat. Utility Model Content

[0005] In order to overcome the common problem of dynamic pressure air bearing radial bearing seat, the bearing temperature inside cannot be monitored during use, which often leads to damage due to excessive temperature after long-term operation, and it is inconvenient to install and fix the bearing. At the same time, during use, the high-speed rotation of the bearing will cause the connection to loosen, resulting in unstable operation.

[0006] The technical solution of the utility model is: a dynamic pressure air bearing radial bearing seat with a temperature warning function, including a bearing seat body, a mounting sleeve fixedly installed on the outer surface of the bearing seat body, and a temperature sensor is provided on the front side of the upper end of the outer surface of the bearing seat body, and the interior of the bearing seat body is slidingly connected to the bearing body, the outer surface of the bearing body is provided with a mounting assembly, and the inner surface of the bearing seat body is provided with a stabilizing assembly.

[0007] Preferably, by setting a temperature sensor, the temperature of the bearing body can be monitored in real time. When the temperature exceeds the working range, the temperature sensor can transmit a signal to the control end, thereby stopping the equipment. In addition, by setting an installation component and a stabilization component, the bearing body can be quickly installed and docked, while improving the stability of the bearing body during operation and reducing shaking, thereby solving the problem that the existing device is inconvenient for installing bearings and cannot monitor the operating temperature in real time.

[0008] Preferably, a mounting screw hole is provided on the front side of the upper surface of the bearing seat body, and the temperature sensor is threadedly connected to the bearing seat body through the mounting screw hole. By providing the mounting screw hole, the temperature sensor can be easily disassembled and assembled, thereby facilitating maintenance and replacement, and the fixing effect is good and not easy to loosen. In addition, by providing a temperature sensor, model P100, the temperature of the bearing body can be monitored in real time.

[0009] Preferably, the depth of the mounting screw hole is slightly smaller than the shell thickness of the bearing seat body. By designing the depth of the mounting screw hole to be slightly smaller than the shell thickness of the bearing seat body, the temperature sensor can be avoided from directly contacting the bearing body, thereby transferring heat through the gap between the bottom of the hole and the other side.

[0010] Preferably, the mounting assembly includes a mounting groove, a slider and a connecting plate. The inner surface of the bearing seat body is provided with mutually symmetrical mounting grooves. The inner sliding connection of the mounting groove is provided with a slider. The outer surface of the slider is welded to a connecting plate. The end of the connecting plate away from the slider is welded to the outer surface of the bearing body. By setting the mounting groove, the slider can slide inside it, thereby facilitating the staff to quickly position and install the bearing body. The slider, connecting plate and bearing body are connected by welding, which can increase the stability of the overall structure and is not prone to loosening after installation.

[0011] Preferably, the mounting assembly includes a card block, which is made of wood and fits into the mounting groove. By setting the card block, after the bearing body is located in the mounting position, the card block is inserted from the top of the mounting groove and the card block is completely knocked into the mounting groove with a wooden hammer, so that the slider can be positioned to avoid sliding during operation. At the same time, the wooden card block will be compressed when knocked in, so that it can better fit into the mounting groove.

[0012] Preferably, the stabilizing component includes a base, a damping block and an arc-shaped liner. The inner surface of the bearing seat body is installed with mutually symmetrical bases. The internal sliding connection of the base is provided with a damping block. The outer surface of the damping block is fixedly installed with an arc-shaped liner. By setting the arc-shaped liner, a limiting effect can be provided for the bearing body. After the bearing body is installed, the two sets of bases, damping blocks and arc-shaped liners will position the bearing body in the center of the bearing seat body, thereby ensuring concentricity and improving operation stability.

[0013] Preferably, the stabilizing component includes a spring, and a spring is provided on the inner bottom surface of the base. The top of the spring is fixedly connected to the damping block. By providing the spring, during operation, the bearing body will produce a small swing due to high-speed rotation. When the swing is transmitted to the spring, the spring contracts, thereby providing buffering, and the rebound effect of the spring can make the arc lining always fit together with the outer surface of the bearing body.

[0014] Beneficial effects of the utility model:

[0015] 1. By setting up a temperature sensor, the temperature of the bearing body can be monitored in real time. When the temperature exceeds the working range, the temperature sensor can transmit a signal to the control end to stop the equipment. In addition, by setting up the installation component and the stabilization component, the bearing body can be quickly installed and docked. At the same time, the stability of the bearing body during operation is improved and shaking is reduced. This solves the problem that the existing device is inconvenient for bearing installation and cannot monitor the operating temperature in real time;

[0016] 2. By setting a temperature sensor, the temperature of the bearing body can be monitored in real time, and the depth of the mounting screw hole is designed to be slightly smaller than the shell thickness of the bearing seat body, which can avoid direct contact between the temperature sensor and the bearing body, thereby transferring heat through the gap between the bottom of the hole and the other side, and by setting a mounting groove, the slider can slide inside it, so that the staff can quickly position and install the shaft body, and the slider, connecting plate and bearing body are connected by welding, which can increase the stability of the overall structure and is not easy to loosen after installation. The arc liner can be provided to provide a limiting effect on the bearing body. After the bearing body is installed, the two sets of bases, damping blocks and arc liners will position the bearing body in the center of the bearing seat body, thereby ensuring concentricity and improving operation stability.

The depth of the mounting screw hole 6 is designed to be slightly smaller than the shell thickness of the bearing seat body 1, which can avoid direct contact between the temperature sensor 3 and the bearing body 4, thereby passing through the gap between the bottom of the hole and the other side.
