Description

Technical Field

[0001] This invention relates to the field of bearing housing technology, specifically to a bearing housing. Background Technology

[0002] Bearing housings are crucial components supporting bearings. By fixing the outer ring of the bearing and allowing the inner ring to rotate, they ensure stable equipment operation. Bearing housings are widely used in mechanical structures such as conveyor belts. Self-aligning bearing housings, benefiting from their spherical inner rings that match the outer ring, allow for a certain torsional fit and are therefore widely used. However, with increased wear and tear, current bearing housings make it difficult to automatically detect misalignment of the inner ring, leading to further wear on the outer ring. Furthermore, they hinder proper oil filling, as direct oil filling can impede oil penetration into the bearing rollers, instead causing excessive seepage between the bearing housing and the outer ring, further promoting outer ring movement. In actual installation, manual bolt tightening is often necessary, making it difficult to automatically control even bolt tightening and affecting installation quality. It also makes it difficult to ensure proper wrench insertion, potentially leading to improper tightening and bolt deformation.

[0003] Therefore, we propose a bearing housing. Summary of the Invention

Two mounting bolts are rotatably installed on the lower pressure frame, and the two mounting bolts pass through the lower pressure frame. The two mounting bolts pass through the two insertion holes.

[0008] Preferably, the device comprises a limiting pin, a pressing bevel, and a rotating shaft. The limiting pin has an L-shaped structure and is located inside the mounting bolt. A rotating shaft is rotatably mounted on the limiting pin and is fixedly inserted into the mounting bolt. The ends of the limiting pin are aligned and inserted into positioning grooves on the same side. The end of the limiting pin has a pressing bevel, and the middle part of the pressing bevel is aligned with the sidewall of the hexagonal hole on the mounting bolt. The end of the pressing bevel is used to be pressed by a hexagonal wrench. The limiting pin is located at the bottom of the hexagonal hole on the mounting bolt.

[0009] Preferably, the wrench detection component further includes: a limiting spring, wherein the limiting spring is fixedly installed on the limiting pin block, and the limiting spring has a V-shaped structure; the top of the limiting spring is fixedly installed inside the mounting bolt; the limiting spring is used to elastically press down the limiting pin block.

[0011] Preferably, the malfunction safety component includes: a safety mounting cylinder, an annular groove, and an indicator light. The safety mounting cylinder is fixedly mounted on the bearing housing body. An annular groove is formed at the bottom of the safety mounting cylinder. The diameter of the annular groove is larger than the inner diameter of the safety mounting cylinder. The safety mounting cylinder is aligned with the inclined groove. An indicator light is fixedly mounted on the safety mounting cylinder.

[0012] Preferably, the misalignment safety component further includes: a stop ball, a contact ring, and a compression spring. The stop ball is fitted inside an annular groove; the stop ball is placed on a sloping groove; the diameter of the stop ball is the same as the inner diameter of the safety mounting cylinder; the sloping groove is used to compress the stop ball to move upward and fit against the safety mounting cylinder when the misalignment occurs; two contact rings are fixedly installed inside the safety mounting cylinder, and there is a gap between the two contact rings; a compression spring is fixedly installed on the upper contact ring, and the compression spring is a bent steel sheet structure with a sloping bottom; the stop ball moves upward to push the compression spring to deform and fit against the lower contact ring; the contact ring, the compression spring, and the indicator light are connected in series with a power supply; the indicator light is used to indicate the misalignment of the outer ring of the bearing.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention employs a wrench detection component to automatically lock the bolt when the operator pulls out the hex wrench after tightening it, preventing the bolt from becoming unscrewed. This allows for seamless operation, avoiding the possibility of forgetting to stop the bolt and ensuring installation stability. Furthermore, the structure utilizes a limiting pin located at the bottom of the hexagonal hole on the bolt, ensuring that the operator must fully insert the hexagonal wrench before tightening. Otherwise, the limiting pin cannot release the inclined surface, preventing insufficient insertion and excessive pressure on the hexagonal hole inside the bolt, which could damage the bolt or cause the wrench to slip.

[0016] By using a uniform tightening component in conjunction with a vertical guide groove, the need for workers to simultaneously rotate two installation bolts during actual tightening can be reduced, thus improving the uniformity of tightening the two installation bolts.

[0017] The use of a lateral movement safety component can detect and indicate lateral movement in the outer ring. It can automatically alert the user if the transmission volume exceeds the limit. Simultaneously, the structure utilizes a stop ball to prevent continued lubrication after excessive lateral movement in the outer ring has occurred. Continuous lubrication can easily cause oil to seep further between the bearing outer ring and the bearing housing, further increasing the instability and lateral movement of the bearing outer ring. The use of an inner ring rotation limiter ensures that the bearing inner ring and rollers can rotate in real time during actual lubrication, increasing the lubricating oil contact area, promoting complete oil filling of the bearing rollers, and improving lubrication quality.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1 to 10 As shown: This invention provides a technical solution: a bearing housing, including a bearing support portion 1, on which a uniform tightening member 2 is installed, the uniform tightening member 2 being used to control uniform force during the installation of the bearing support portion 1; two wrench detection members 3 are installed on the uniform tightening member 2; the wrench detection members 3 are used to prevent the wrench from not being properly inserted into the uniform tightening member 2; an outer ring portion 4 is installed on the bearing support portion 1; a slippage prevention member 5 is installed on the bearing support portion 1; an inner ring rotation restriction member 6 is installed on the slippage prevention member 5; the inner ring rotation restriction member 6 is used to restrict the rotation of the bearing inner ring during oil injection; the bearing support portion 1 includes: a bearing housing body 101 and a vertical guide groove 1011, the bearing housing body 101 having two vertical guide grooves 1011; the two vertical guide grooves 1011 are used to vertically guide the uniform tightening member 2.

[0022] The bearing support portion 1 further includes: insertion holes 1012, with two insertion holes 1012 provided on the bearing housing body 101; the two insertion holes 1012 are located on both sides of two vertical guide grooves 1011 respectively; the uniform tightening component 2 includes: a lower pressure frame 201, guide blocks 2011, positioning grooves 2012 and mounting bolts 202, the lower pressure frame 201 is located on the outside of the bearing housing body 101; guide blocks 2011 are fixedly installed on both sides inside the lower pressure frame 201, and the two guide blocks 2011 are slidably inserted into the two vertical guide grooves 1011 respectively; two rings of positioning grooves 2012 are provided on the lower pressure frame 201; the two rings of positioning grooves 2012 are aligned with the two insertion holes 1012 respectively; two mounting bolts 202 are rotatably installed on the lower pressure frame 201, and the two mounting bolts 202 pass through the lower pressure frame 201 respectively; the two mounting bolts 202 passes through two insertion holes 1012 respectively; the mounting bolt 202 is provided with a hexagonal hole for inserting a wrench; the mounting bolt 202 is used for threaded connection to the bearing housing mounting bracket; by using the uniform tightening component 2 in conjunction with the vertical guide groove 1011, it can be achieved that when the operator is actually tightening the mounting bolt 202, both mounting bolts 202 need to be rotated at the same time for tightening work, otherwise the mounting bolt 202 on the other side will get stuck if it is not screwed into the threaded hole. The vertical guide groove 1011 is used for limiting and guiding. Since there are two mounting bolts 202 rotatably mounted on the lower pressure frame 201, if only one side of the mounting bolt 202 is rotated, the other side of the mounting bolt 202 will get stuck because it cannot rotate and move down. This improves the uniformity of the operator when tightening the two mounting bolts 202.

[0023] The device comprises a limiting pin 301, a pressing inclined surface 3011, and a rotating shaft 302. The limiting pin 301 has an L-shaped structure and is located inside the mounting bolt 202. The rotating shaft 302 is rotatably mounted on the limiting pin 301 and is fixedly inserted into the mounting bolt 202. The ends of the limiting pin 301 are aligned and inserted into the positioning groove 2012 on the same side. The end of the limiting pin 301 is provided with a pressing inclined surface 3011, and the middle part of the pressing inclined surface 3011 and the side wall of the hexagonal hole on the mounting bolt 202 are aligned. The end of the extrusion bevel 3011 is used to be pressed by a hexagonal wrench; the limiting pin block 301 is located at the bottom of the hexagonal hole on the mounting bolt 202; the wrench detection component 3 also includes: a limiting spring 303, which is fixedly installed on the limiting pin block 301, and the limiting spring 303 has a V-shaped structure; the top of the limiting spring 303 is fixedly installed inside the mounting bolt 202; the limiting spring 303 is used to elastically press down the limiting pin block 301. The use of the wrench detection component 3 can assist the operator in tightening the mounting bolt. After bolt 202 is engaged, the automatic control locks bolt 202 when the hex wrench is pulled out, preventing bolt 202 from becoming unscrewed. This allows for seamless operation by the operator, preventing the operator from forgetting to stop bolt 202 and ensuring its installation stability. Furthermore, the structure utilizes a limiting pin 301 located at the bottom of the hexagonal hole on bolt 202, ensuring that the operator must fully insert the hex wrench before tightening the bolt. Otherwise, the limiting pin 301 cannot release the limiting action of the insertion-compression bevel 3011. By restricting the operator's operation to require full insertion of the hex wrench, this structure effectively improves the safety of tightening bolt 202, especially for torque wrenches. It prevents insufficient insertion of the hex wrench from causing excessive pressure concentration on the hexagonal hole inside bolt 202, which could damage the bolt or cause the wrench to slip. This structure ensures the service life of bolt 202 and guarantees the stability of bearing support and fastening.

[0024] The outer ring 4 includes: a bearing outer ring 401 and a beveled groove 4011. The bearing outer ring 401 is fitted inside the bearing housing body 101. The bearing outer ring 401 has a beveled groove 4011. The bottom of the beveled groove 4011 passes through the bearing outer ring 401. The beveled groove 4011 has a tapered bevel structure. A groove is formed on the beveled groove 4011. The groove is used for the flow of lubricating oil. The slippage safety element 5 includes: a safety mounting cylinder 501, an annular groove 5011, and an indicator light 502. The safety mounting cylinder 501 is fixedly mounted on the bearing housing body 101. The bottom of the safety mounting cylinder 501 has an annular groove 5011. The diameter of the annular groove 5011 is larger than the inner diameter of the safety mounting cylinder 501. The safety mounting cylinder 501 is aligned with the beveled groove 4011. An indicator light 502 is fixedly mounted on the safety mounting cylinder 501. Component 5 also includes: a stop ball 503, a contact ring 504, and a compression spring 505. The stop ball 503 is sleeved inside the annular groove 5011; the stop ball 503 is placed on the inclined groove 4011; the diameter of the stop ball 503 is the same as the inner diameter of the safety mounting cylinder 501; the inclined groove 4011 is used to compress the stop ball 503 to move upward and fit against the safety mounting cylinder 501 when it moves and the safety mounting cylinder 501 is misaligned; two contact rings 504 are fixedly installed inside the safety mounting cylinder 501, and there is a gap between the two contact rings 504; a compression spring 505 is fixedly installed on the upper contact ring 504, and the compression spring 505 is a bent steel sheet structure with an inclined bottom; the stop ball 503 moves upward and pushes the compression spring 505 to deform and fit against the lower contact ring 504; the contact ring 504, the compression spring 505, and the indicator light 502 are connected in series with a power supply.The indicator light 502 is used to indicate misalignment of the outer ring 401 of the bearing. The misalignment safety device 5 is used to detect and indicate misalignment of the outer ring 4. If the transmission amount exceeds the limit, an automatic warning will be issued. This prevents the outer ring 4 from easily wearing down due to its spherical self-aligning characteristics during long-term use, which could lead to misalignment within the bearing housing 101, increasing vibration and wear. Simultaneously, the structure utilizes a stop ball 503 to prevent continued lubrication after excessive misalignment of the outer ring 4. If the outer ring 4 misaligns, the inclined groove 4011 is no longer aligned with the safety mounting sleeve 501, preventing normal oil supply. Continuing to inject oil could also cause further seepage between the bearing outer ring 401 and the bearing housing 101, further increasing the bearing's wear. This structure can automatically control and seal the unstable movement of the outer ring 401. The structure is simple and reasonable. In actual use, if the outer ring 401 becomes stuck due to wear and lack of lubrication, it will move within the bearing housing body 101. If the movement exceeds the limit, the outer ring 401 will shift. The inclined surface of the inclined groove 4011 can press the stop ball 503 upwards. The stop ball 503 then inserts into the safety mounting cylinder 501 for sealing, preventing normal lubrication injection. Simultaneously, the upward movement of the stop ball 503 will press against the bottom inclined surface of the compression spring 505, causing it to shift and engage with the lower electrical contact ring 504. This activates the circuit, illuminating the indicator light 502. Manual intervention is required to disassemble the bearing for repair.

[0025] In Example 2, based on Example 1, the inner ring rotation limiting component 6 includes: an oil injection pipe 601, which is fixedly installed on the safety mounting cylinder 501; the oil injection pipe 601 is used to connect to the grease gun; the inner ring rotation limiting component 6 also includes: a solenoid valve 602, which is fixedly installed on the oil injection pipe 601; the solenoid valve 602 is electrically connected to the drive source of the bearing installed inside the bearing housing body 101. When using the inner ring rotation limiting component 6 to lubricate and inject oil into bearings such as those on conveyor belts, the solenoid valve 602 can be connected in series with the drive source of the bearing installed inside the bearing housing body 101, i.e., the drive motor. This ensures that the drive source is kept in the open state during actual oil injection, i.e., the inner ring of the bearing is in the rotating state. Only then can the bearing housing body 101 be injected with oil normally. This ensures that the inner ring and rollers of the bearing can rotate in real time during actual oil injection, increasing the contact area of ​​the lubricating oil, promoting the full filling of the bearing rollers with oil, and reducing the probability of lubricating oil overflowing directly from the dust seals on both sides after local accumulation. The actual operation is simple.

[0026] The working principle of this embodiment is as follows: First, when it is necessary to thread the mounting bolts 202 onto the bearing housing body 101 of the conveyor belt bearing housing mounting bracket, two hex wrenches are used simultaneously to insert the two mounting bolts 202 respectively and tighten them at the same time. This causes the lower pressure frame 201 to move down and press and tighten the bearing housing body 101. Because there are two mounting bolts 202 rotatably mounted on the lower pressure frame 201, if only one side of the mounting bolt 202 is rotated, the other side's mounting bolt 202 will become stuck because it cannot rotate down. This allows the worker to tighten the two mounting bolts. The uniformity of bolt 202; after the hex wrench is fully inserted into the bolt 202, the end of the hex wrench presses against the pressing bevel 3011. When the pressing bevel 3011 is pressed, it drives the limit pin 301 to rotate. At this time, the limit pin 301 tilts upward and no longer inserts into the positioning groove 2012 for limiting, and the bolt 202 can be rotated normally. After the bolt 202 is installed, when the hex wrench is pulled out, the pressing bevel 3011 is no longer pressed. Under the pressure of the limit spring 303, the limit pin 301 rotates downward again and inserts into the positioning groove 2012 for limiting, preventing the bolt 202 from loosening. When lubrication is required, because it is a series circuit, the conveyor belt drive motor is kept energized and started. At this time, the solenoid valve 602 will also be energized and opened. The lubrication pipe 601 can be connected to the grease gun for lubrication. Under normal conditions, the inclined groove 4011 is aligned with the safety mounting cylinder 501, and the stop ball 503 is fitted inside the annular groove 5011 with some play. During lubrication, oil can flow between the stop ball 503 and the annular groove 5011, and flow into the bearing roller surface for lubrication through the groove on the inclined groove 4011. However, in actual use, if the bearing outer ring 401 becomes stuck due to wear and lack of lubrication of the rollers, the bearing may experience problems. The outer ring 401 moves within the bearing housing body 101. If the amount of movement exceeds the limit, the outer ring 401 will shift. The inclined structure of the inclined groove 4011 can squeeze the stop ball 503 upward. At this time, the stop ball 503 moves upward and inserts into the safety mounting cylinder 501 to seal it. At this time, the lubricating oil injection cannot be performed normally. At the same time, if the amount of movement of the inclined groove 4011 exceeds the limit, the upward movement of the stop ball 503 will squeeze the bottom inclined surface of the compression spring 505. The compression spring 505 will shift and fit against the lower contact ring 504. At this time, the circuit is connected and the indicator light 502 can be controlled to light up to indicate the problem.
