Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, and more specifically, to a bidirectional mounting and fixing bearing housing. Background Technology

[0002] A bidirectional bearing housing is a mechanical component used to install and secure bearings. It allows bearings to be installed and secured in two directions to adapt to different working requirements and installation scenarios. This type of bearing housing typically has a symmetrical structural design, with identical or similar mounting interfaces and fixing methods at both ends or sides. This allows bearings to be installed from two different directions while ensuring good stability and reliability after installation. Bidirectional bearing housings effectively improve the installation accuracy and positioning precision of bearings, reducing bearing wear and equipment failure caused by installation errors. At the same time, it also provides greater flexibility in equipment design and maintenance, facilitating the installation, disassembly, and replacement of bearings under different operating conditions.

[0003] Although the device has many beneficial effects, the following problems still exist: However, the existing bidirectional mounting and fixing bearing housings are mostly fixed to the bearings by multiple bolts during actual installation. This is extremely cumbersome during installation and use. It requires personnel to use special tools to disassemble and install it. Furthermore, during installation, personnel need to provide additional support to the bearings before the two clamping surfaces are tightly pressed against the bearings for fixing and clamping. However, this installation method is extremely inconvenient.

[0004] Furthermore, existing bidirectional fixed bearing housings generate heat during actual use due to rolling friction and viscous friction of lubricating oil. If heat is not dissipated in time, the heat accumulation will cause the bearing temperature to rise significantly. This will not only deteriorate the performance of the lubricating grease, reduce the lubrication effect, and aggravate bearing wear, but may also cause the bearing housing material to lose strength and deform due to high temperature, affecting its precise support and fixation of the bearing. This undoubtedly causes great trouble in actual use.

[0005] In view of this, we propose a bidirectional mounting and fixing bearing housing. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] The purpose of this invention is to provide a bidirectional mounting and fixing bearing housing to solve the problems mentioned in the background art.

[0008] 2. Technical Solution

[0009] A bidirectional mounting and fixing bearing housing includes a lower bearing housing and an upper bearing housing. The lower bearing housing has a snap-fit ​​sleeve on its top. A rotating handle is threaded onto the outer wall of a plurality of snap-fit ​​sleeves. A fixing bolt is threaded onto the outer wall of the rotating handle. A pressure rod is connected to the outer circumferential wall of the end of the rotating handle. Limiting square holes are also formed on the outer wall of the plurality of snap-fit ​​sleeves. A limiting circular groove matching the fixing bolt is also formed on one side of the outer wall of the plurality of snap-fit ​​sleeves. A snap-fit ​​bracket matching the snap-fit ​​sleeve is provided at the bottom of the upper bearing housing. A cooling fan is provided at the top of the upper bearing housing.

[0010] Preferably, the clamping surfaces of the lower bearing seat and the upper bearing seat are both connected to a limiting plate and a second rubber pad, and the outer walls of the plurality of limiting plates are adhered with a first rubber pad.

[0011] Preferably, both the lower bearing housing and the upper bearing housing have cavities inside, and the cavities inside the lower bearing housing and the upper bearing housing are connected.

[0012] Preferably, the inner walls of the cavities inside the lower bearing housing and the upper bearing housing are provided with ventilation openings and through openings, and the outer walls of the plurality of rubber pads are provided with openings corresponding to the through openings.

[0013] Preferably, the inner wall of the card holder has slots on both sides, and springs are connected to the inner walls of multiple slots. The ends of multiple springs are connected to limiting blocks that match the limiting square holes.

[0014] Preferably, the inner walls of the plurality of slots are further provided with sliding grooves, and the outer walls of the plurality of limiting blocks are further provided with sliding blocks that match the sliding grooves.

[0015] 3. Beneficial effects

[0016] Compared to existing technologies, the advantages of this invention are as follows: During actual installation, the bearing can be placed between the two limiting plates at the top of the lower bearing seat. Then, the snap-fit ​​bracket at the bottom of the upper bearing seat is snapped into the snap-fit ​​sleeve, allowing the bearing to be positioned using the two limiting plates at the bottom of the upper bearing seat. The upper bearing seat is then pressed down to its limit position, and multiple rotating handles are rotated 90 degrees. This keeps the two pressure rods on the outer circumference of the ends of the multiple rotating handles horizontal, thus pressing against the two limiting blocks and allowing them to snap into the corresponding limiting square holes. The lower and upper bearing seats then clamp the bearing for stable support. The fixing bolt is then rotated into the limiting groove, maintaining the horizontal state of the pressure rods and improving the stability of the fixation. When the bearing needs to be disassembled, the fixing bolt can be rotated to loosen it away from the limiting groove, and then the rotating handles can be reset. Subsequently, due to the release of the pressure from the two limiting blocks, multiple springs can drive the limiting blocks to reset and move away from the limiting square holes. Then, the lower bearing housing and the upper bearing housing can be directly separated, making it easier for personnel to repair or replace the bearing. The overall installation is simpler and more convenient. Furthermore, due to the function of multiple limiting plates, the bearing can be positioned and supported more easily during installation, reducing the need for personnel to use tools or hand support for auxiliary installation, thus improving the convenience of personnel installation. In addition, the bearing housing clamping surface is equipped with rubber pad one and rubber pad two, which can absorb and weaken these vibrations and impacts during bearing operation, reducing their impact on the bearing and bearing housing. The elasticity and high coefficient of friction of rubber can be used to increase the friction between the clamping surface and the bearing, making the bearing more stable after installation, effectively preventing the bearing from shifting or shaking during operation, and improving the clamping effect of the bearing housing on the bearing.

[0017] Furthermore, in actual use, the lower and upper bearing housings have internal cavities that are interconnected. When the bearing rotates due to friction for a long time, airflow can be generated by the cooling fan to enter the multiple cavities, and the bearing can be cooled by the airflow. Excess heat will be discharged through multiple vents, improving the heat dissipation performance of the bearing housing when the bearing is installed and used, and ensuring its continuous and stable use.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] A bidirectional mounting and fixing bearing housing includes a lower bearing housing 100 and an upper bearing housing 200. The top of the lower bearing housing 100 is provided with a snap-fit ​​sleeve 110. A rotating handle 120 is threadedly sleeved on the outer wall of a plurality of snap-fit ​​sleeves 110. A fixing bolt 121 is threadedly sleeved on the outer wall of the rotating handle 120. A pressure rod 122 is connected to the outer circumferential wall of the end of the rotating handle 120.

[0028] In some embodiments, both the rotating handle 120 and the pressing rod 122 are made of metal.

[0029] Multiple snap-fit ​​sleeves 110 have limit square holes 130 on their outer walls, and multiple snap-fit ​​sleeves 110 have limit circular grooves on one side of their outer walls that match the fixing bolts 121. The bottom of the upper bearing seat 200 is provided with a snap-fit ​​bracket 210 that matches the snap-fit ​​sleeves 110, and the top of the upper bearing seat 200 is provided with a cooling fan 220.

[0030] In some embodiments, the cooling fan 220 may be a Rundar AC25489 series, which is existing technology.

[0031] Specifically, both the lower bearing housing 100 and the upper bearing housing 200 have a limiting plate 250 and a second rubber pad 270 connected to their clamping surfaces. Multiple limiting plates 250 have rubber pads 251 adhered to their outer walls. This facilitates bearing positioning and provides cushioning during installation, enhancing buffering performance.

[0032] Furthermore, both the lower bearing housing 100 and the upper bearing housing 200 have cavities 230 inside, and the cavities 230 inside the lower bearing housing 100 and the upper bearing housing 200 are connected, so that the airflow for heat dissipation can be conducted, thereby achieving comprehensive air cooling.

[0033] Furthermore, the inner walls of the internal cavities 230 of the lower bearing housing 100 and the upper bearing housing 200 are provided with ventilation openings 240 and through openings 260, and the outer walls of the multiple rubber pads 270 are provided with openings corresponding to the through openings 260, so as to facilitate better heat dissipation.

[0034] In some embodiments, the outer walls of rubber pad 270 and rubber pad 251 are provided with anti-slip textures to improve the friction during clamping and installation, and to ensure the stability of clamping and installation.

[0035] Furthermore, slots 211 are provided on both sides of the inner wall of the snap-fit ​​bracket 210, and springs 215 are connected to the inner walls of multiple slots 211. The ends of multiple springs 215 are connected to limiting blocks 213 that match the limiting square holes 130, which facilitates the installation of the lower bearing seat 100 and the upper bearing seat 200.

[0036] It is worth noting that the inner walls of the multiple slots 211 are also provided with sliding grooves 212, and the outer walls of the multiple limiting blocks 213 are also provided with sliding blocks 214 that match the sliding grooves 212, so as to guide the two limiting blocks 213 when pressing.

[0037] In some embodiments, the cooling fan 220 used in the device can be connected to an external power supply and control switch. Furthermore, the lower bearing seat 100, upper bearing seat 200, snap-fit ​​sleeve 110, and snap-fit ​​bracket 210 of the device are all metal structures to ensure the stability of the structure.

[0038] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0039] Working principle: During actual installation, the bearing can be placed between the two limiting plates 250 at the top of the lower bearing housing 100. Then, the snap-fit ​​bracket 210 at the bottom of the upper bearing housing 200 is snapped into the snap-fit ​​sleeve 110, so that the bearing is positioned by the two limiting plates 250 at the bottom of the upper bearing housing 200. Then, the upper bearing housing 200 is pressed down to the limit position, and then the multiple rotating handles 120 are rotated 90 degrees, and the two abutment rods 122 on the outer circumference of the end of the multiple rotating handles 120 are engaged. Maintaining a horizontal position, the two limiting blocks 213 are pressed against each other, allowing them to engage in the corresponding limiting square holes 130. This, in turn, utilizes the clamping mechanism of the lower bearing seat 100 and the upper bearing seat 200 to provide stable support for the bearing. Then, the fixing bolt 121 is rotated into the limiting circular groove, further maintaining the horizontal position of the pressing rod 122 and improving its stability. When disassembly of the bearing is required, the fixing bolt 121 can be rotated to loosen it and move it away from the limiting circular groove. Then, the rotating handle 1... After the two limiting blocks 213 are released from their pressure, the multiple springs 215 can drive the limiting blocks 250 to reset and move away from the limiting square holes 130. Then, the lower bearing housing 100 and the upper bearing housing 200 can be directly separated, making it easier for personnel to repair or replace the bearing. The overall installation is simpler and more convenient. Due to the function of the multiple limiting plates 213, the bearing can be positioned and supported more conveniently during installation, reducing the need for personnel to use tools or hold the bearing by hand, thus improving the convenience of installation. In actual use, the lower bearing housing 100 and the upper bearing housing 200 have cavities 230 inside, and the multiple cavities 230 are interconnected. When the bearing rotates for a long time, the cooling fan 220 can generate airflow into the multiple cavities 230 to dissipate some heat from the bearing by blowing air. The excess heat will be discharged through the multiple vents 240, improving the heat dissipation performance of the bearing housing when the bearing is installed and used, and ensuring its continuous and stable use.
