Description

Technical Field

[0001] This application relates to the technical field of mechanical transmission, and in particular to a roller bearing housing. Background Technology

[0002] Idler roller bearing housings are crucial components used to support and position idler roller bearings, and are widely used in rolling equipment in industries such as steel, non-ferrous metals, metallurgy, and mining. They withstand high loads and high-speed operation, making them essential for the stability and normal operation of the idler rollers.

[0003] Idler rollers generate a significant amount of heat during operation, requiring effective heat dissipation from the bearing housings to prevent overheating, poor lubrication, or thermal deformation. Current technologies largely rely on air cooling, which is ineffective and prevents the idler rollers from operating for extended periods.

[0004] In summary, to prevent problems such as bearing overheating, poor lubrication, or thermal deformation during long-term operation of the idler rollers, it is necessary to improve the heat dissipation performance of the idler roller bearing housing. Summary of the Invention

[0005] To improve the heat dissipation performance of idler roller bearing housings, this application provides an idler roller bearing housing.

[0006] This application provides a roller bearing housing, which adopts the following technical solution: A roller bearing housing includes a fixing plate with a through-hole for fixing, and a mounting base fixedly mounted on the fixing plate. The mounting base has a through-hole, and a sealing cover is coaxially disposed on the mounting hole. The sealing cover is detachably fixedly connected to the mounting base. The mounting base also includes a heat dissipation mechanism, which comprises: A medium channel is provided, which is formed around the mounting hole, and the inlet and outlet of the medium channel are both formed on the side wall of the mounting base; A pump, which is fixedly mounted on the fixed plate, and the outlet of the pump is connected to the inlet of the medium channel; A media storage tank is fixedly mounted on the fixing plate, the media storage tank is connected to the inlet of the pump, and the media storage tank is connected to the outlet of the media channel; A control component is disposed on the mounting base and is used to control the flow rate of the medium.

[0007] By adopting the above technical solution, when the medium flows in the medium channel, the heat generated by the bearing rotation is carried away and flows back to the medium storage tank. Furthermore, the flow rate of the medium in the medium channel is accelerated by the control mechanism to improve the heat dissipation capacity, thereby further improving the heat dissipation performance of the idler roller bearing housing.

[0008] Optionally, the control component includes: A detection slot is formed on the mounting base; A sliding block is slidably installed in the detection groove, and the sliding block and the detection groove form a sealed cavity; A first rack, one end of which is fixedly mounted on the sliding block, the length direction of which is along the sliding direction of the sliding block; A gear, rotatably mounted on the mounting base, meshing with the first rack; The second rack meshes with the gear; A chute is formed on the mounting base and communicates with the medium channel; A blocking block is slidably installed in the slide groove and is fixedly connected to the second rack. The sliding direction of the blocking block is the same as the length direction of the second rack.

[0009] By adopting the above technical solution, the high temperature generated by the rotation of the bearing is used to heat the gas in the sealed cavity, so that the gas expansion becomes the driving force of the sliding block. The power is transmitted through the first rack, gear and the second rack, driving the plug to reduce the flow area of ​​the medium channel, accelerate the medium flow rate and improve the heat dissipation performance.

[0010] Optionally, it may also include an auxiliary heat dissipation mechanism, which includes: A cooling fan is fixedly mounted on the mounting base, and the cooling fan faces the position where the media channel outlet communicates with the media storage box; A controller is fixedly mounted on the mounting plate and is electrically connected to the cooling fan. A temperature sensor is provided, with its detection end positioned at a location where the media storage tank communicates with the media channel, and the temperature sensor is electrically connected to the controller.

[0011] By adopting the above technical solution, the temperature of the medium that has absorbed heat is detected, and the power of the cooling fan is controlled accordingly, so that the medium that has absorbed heat can further dissipate heat, thereby improving the heat dissipation performance.

[0012] Optionally, the mounting base is provided with a self-lubricating mechanism, the self-lubricating mechanism comprising: A push rod is inserted through and slidably mounted on the mounting base at one end away from the fixed plate. One end of the push rod is a ramp, and the ramp end of the push rod is located in the mounting hole, with the ramp end of the push rod facing the mounting surface of the mounting base. A first spring, one end of which is fixedly connected to the mounting base, and the other end of which is fixedly connected to the push rod; An oil storage chamber is provided at the end of the mounting base away from the fixed plate; A first oil pipe is provided on the mounting base, and one end of the first oil pipe is connected to the oil storage cavity. The second oil pipe is provided on the push rod. One end of the second oil pipe is connected to the end of the first oil pipe away from the oil storage cavity, and the other end of the second oil pipe can be coaxial with the oil nozzle of the bearing to be installed. The grease injection hole is located on the mounting base, and one end of the grease injection hole is connected to the oil storage cavity.

[0013] By adopting the above technical solution, the second oil pipe is connected to the first oil pipe by using the bearing moving push rod, thus realizing automatic lubrication of the bearing and avoiding the situation of insufficient grease in the bearing and severe overheating.

[0014] Optionally, the self-lubricating mechanism further includes a positioning component, the positioning component comprising: A pin groove is formed on the side wall of the mounting hole, and the length direction of the pin groove is along the length direction of the mounting hole; A pin, which abuts against the pin groove.

[0015] By adopting the above technical solution, the installation position of the bearing is limited by the pin groove and pin shaft, ensuring that the oil nozzle and the second oil pipe can be coaxially aligned during the installation of the bearing, thereby improving the installation efficiency of the bearing.

[0016] Optionally, the grease injection hole is internally threaded with an oil plug.

[0017] By adopting the above technical solution, impurities are prevented from entering the oil injection hole and then entering the bearing raceway along with the grease, thus affecting the service life of the bearing.

[0018] Optionally, a buffer pad is fixedly installed on the end of the fixing plate away from the mounting base.

[0019] By adopting the above technical solution, the buffer pad can absorb the load generated during bearing operation and ensure the stability of the bearing housing.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. When the medium flows in the medium channel, the heat generated by the bearing rotation is carried away and flows back to the medium storage tank. Furthermore, the flow rate of the medium in the medium channel is accelerated by the control mechanism to improve the heat dissipation capacity, thereby further improving the heat dissipation performance of the idler roller bearing housing. 2. High-temperature heating causes gas expansion, which serves as the driving force for the sliding block. The power is transmitted through the first rack, gear, and second rack, driving the plug to reduce the flow area of ​​the medium channel, accelerate the medium flow rate, and improve heat dissipation performance. 3. By using the bearing to move the push rod, the second oil pipe is connected to the first oil pipe, realizing automatic lubrication of the bearing and avoiding insufficient grease in the bearing, which can lead to severe overheating.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a roller bearing housing.

[0025] Reference Figure 1 The idler roller bearing housing includes a fixed plate 1, a fixed hole 11 is provided through the fixed plate 1, a mounting base 2 is fixedly installed on the fixed plate 1, a mounting hole 21 is provided through the mounting base 2, a sealing cover 3 is coaxially provided on the mounting hole 21, the sealing cover 3 is detachably fixedly connected to the mounting base 2, and a heat dissipation mechanism is also provided on the mounting base 2.

[0026] Reference Figure 2 and Figure 3The heat dissipation mechanism includes a medium channel 41, which surrounds the mounting hole 21. Both the outlet and inlet of the medium channel 41 are located on the side wall of the mounting base 2. The outlet of a pump 42 flows through the inlet of the medium channel 41. The pump 42 is fixedly mounted on the mounting plate 1. The inlet of the pump 42 connects to a medium storage tank 43, which is also fixedly mounted on the mounting plate 1. The medium storage tank 43 communicates with the outlet of the medium channel 41. The heat dissipation mechanism also includes a control component 44, which is mounted on the mounting base 2 and is used to control the medium flow rate.

[0027] Before use, the bearing to be installed is first fixedly installed in the mounting hole 21. Then, the sealing cover 3 is fixedly installed on the mounting base 2 with bolts, and the fixing plate 1 is fixedly installed in the required position by bolts through the fixing hole 11, thus completing the fixed installation of the bearing and bearing housing. When the bearing is in use, the pump 42 is started. The pump 42 delivers the medium from the medium storage tank 43 to the medium channel 41. The medium flows in the medium channel 41, carrying away the heat generated by the rotation of the bearing and flowing back to the medium storage tank 43. The flow rate of the medium in the medium channel 41 can be increased by the control mechanism to improve the heat dissipation capacity. Compared with the commonly used air cooling, the heat dissipation capacity is improved.

[0028] Reference Figure 3 The control component 44 includes a detection groove 441, which is formed on the mounting base 2. A sliding block 442 is slidably installed in the detection groove 441, forming a sealed cavity with the detection groove 441. A first rack 443 is fixedly installed on the sliding block 442, and the length direction of the first rack 443 is the same as the sliding direction of the sliding block 442. The first rack 443 meshes with a gear 444, which is rotatably installed on the mounting base 2. The gear 444 meshes with a second rack 445, which is fixedly connected to a blocking block 447. The blocking block 447 is slidably installed in a sliding groove 446, which is formed on the mounting base 2 and communicates with the medium channel 41. The sliding direction of the blocking block 447 is the same as the length direction of the second rack 445.

[0029] When the bearing rotates and generates a large amount of heat, the temperature of the mounting base 2, which is fixedly connected to the outer ring of the bearing, rises accordingly. The increased temperature of the mounting base 2 causes the gas in the sealing cavity to expand. The gas expansion pushes the sliding block 442 to move, and the first rack 443, which is fixedly connected to the sliding block 442, also moves accordingly. The first rack 443 drives the gear 444 to rotate, and the rotation of the gear 444 drives the second rack 445 to move. The block 447, which is fixedly connected to the second rack 445, also moves accordingly. The block 447 enters the medium channel 41, reducing the flow area of ​​the medium channel 41 and increasing the flow velocity of the medium in the medium channel 41, thereby improving the heat dissipation performance.

[0030] Reference Figure 2 The idler roller bearing housing also includes an auxiliary heat dissipation mechanism 5, which includes a cooling fan 51. The cooling fan 51 is fixedly installed on the mounting base 2 and faces the position where the media channel 41 communicates with the media storage box 43. The cooling fan 51 is electrically connected to a controller 52, which is fixedly installed on the mounting plate 1. The controller 52 is electrically connected to a temperature sensor 53, and the detection end of the temperature sensor 53 is located at the position where the media storage box 43 communicates with the media channel 41.

[0031] Temperature sensor 53 detects the temperature of the medium that has absorbed heat. When the medium temperature is too high, temperature sensor 53 feeds a signal back to controller 52, which increases the output power of cooling fan 51 to further dissipate heat from the medium that has absorbed heat, thereby improving heat dissipation performance.

[0032] Reference Figure 1 A buffer pad 7 is fixedly installed on the end of the fixing plate 1 away from the mounting base 2.

[0033] The buffer pad 7 can absorb the load generated during bearing operation and ensure the stability of the bearing housing.

[0034] Reference Figure 4 and Figure 5 The mounting base 2 is equipped with a self-lubricating mechanism, which includes a push rod 61. The push rod 61 passes through and slides on the end of the mounting base 2 away from the fixed plate 1. One end of the push rod 61 is a ramp, which is located inside the mounting hole 21 and faces the mounting surface of the mounting base 2. One end of the first spring 62 is fixedly connected to the end of the push rod 61 away from the ramp, and the other end of the first spring 62 is fixedly connected to the mounting base 2. The self-lubricating mechanism also includes an oil reservoir. The oil reservoir 63 is located on the end of the mounting base 2 away from the fixed plate 1. The oil reservoir 63 is connected to one end of the first oil pipe 64, which is located on the mounting base 2. The other end of the first oil pipe 64 can be connected to the second oil pipe 65, which is located on the push rod 61. The end of the second push rod 61 away from the first oil pipe 64 can be coaxial with the grease nipple of the bearing to be installed. The oil reservoir 63 is connected to one end of the grease injection hole 66, which is located on the mounting base 2.

[0035] When the bearing is installed into the mounting hole 21, the inclined end of the push rod 61 will be pushed away from the mounting hole 21. At this time, the second oil pipe 65 on the push rod 61 is connected to the first oil pipe 64. The grease in the oil reservoir 63 will flow into the first oil pipe 64 and the second oil pipe 65 in sequence under the action of gravity, and then into the grease nipple of the bearing, thus completing the automatic lubrication of the bearing. Maintenance personnel can replenish the grease in the oil reservoir 63 in time through the grease injection hole 66 to avoid insufficient grease in the bearing and serious overheating.

[0036] Reference Figure 2 The self-lubricating mechanism also includes a positioning component 67, which includes a pin groove 671. The pin groove 671 is formed on the side wall of the mounting hole 21, and the length of the pin groove 671 is formed along the length direction of the mounting hole 21. A pin shaft 672 abuts inside the pin groove 671.

[0037] The outer ring sidewall of the bearing has a groove of the same size and direction as the pin groove 671. When installing the bearing, the pin 672 is first placed into the pin groove 671, and then the groove on the bearing is installed onto the pin 672. This ensures that the oil nozzle and the second oil pipe 65 can be coaxially aligned during the installation of the bearing, thus improving the installation efficiency of the bearing.

[0038] Reference Figure 4 The grease injection hole 66 is internally threaded and has an oil plug 68.

[0039] After the maintenance personnel have replenished the grease in the oil reservoir 63, they should screw the oil plug 68 into the oil filling hole to prevent impurities from entering the oil filling hole and entering the bearing raceway along with the grease, which would affect the service life of the bearing.

[0040] The implementation principle of a roller bearing housing according to an embodiment of this application is as follows: First, the bearing is installed into the mounting hole 21. When the bearing is installed into the mounting hole 21, it pushes the inclined end of the push rod 61 away from the mounting hole 21. At this time, the second oil pipe 65 on the push rod 61 is connected to the first oil pipe 64. The grease in the oil storage chamber 63 can flow into the first oil pipe 64 and the second oil pipe 65 in sequence under the action of gravity, and then into the grease nipple of the bearing, completing the automatic lubrication of the bearing. Then, the sealing cover 3 is fixedly installed on the mounting base 2 with bolts, and the fixing plate 1 is fixedly installed in the required position by bolts passing through the fixing hole 11, completing the fixed installation of the bearing and the bearing housing. When the bearing is in use, the pump 42 is started. The pump 42 delivers the medium from the medium storage tank 43 to the medium channel 41, and the medium flows in the medium channel 41. When the bearing rotates and generates a large amount of heat, the temperature of the mounting base 2, which is fixedly connected to the outer ring of the bearing, rises accordingly. This temperature increase causes the gas inside the sealed cavity to expand, pushing the sliding block 442 to move. The first rack 443, fixedly connected to the sliding block 442, also moves accordingly. The first rack 443 drives the gear 444 to rotate, which in turn drives the second rack 445 to move. The blocking block 447, fixedly connected to the second rack 445, also moves accordingly, entering the medium channel 41. This reduces the flow area of ​​the medium channel 41 and increases the flow velocity of the medium within it. The medium, having absorbed a large amount of heat, flows back from the outlet of the medium channel 41 into the medium storage tank 43. During this return flow, the temperature sensor 53 detects the temperature of the medium that has absorbed heat. When the medium temperature is too high, the temperature sensor 53 sends a signal back to the controller 52. The controller 52 increases the output power of the cooling fan 51 to further dissipate heat from the medium, improving its heat dissipation performance. By absorbing the heat generated by the bearing rotation through a medium, the heat dissipation performance is improved compared to the current method of relying on airflow to remove heat.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
