Description

Technical Field

[0001] This utility model relates to the technical field of bearing support devices, and more specifically to a combined bearing housing. Background Technology

[0002] Bearing housings are crucial components in mechanical systems used to support, secure, and protect bearings. Their core function is to provide stable external support for the bearings, ensuring reduced friction and vibration during shaft rotation, thereby extending equipment life. Bearing housings can be divided into integral and modular types, the difference being the detachability of the bearing core. Due to the wear and tear inherent in bearings during use, modular bearing housings facilitate maintenance and are widely used in mechanical structures.

[0003] However, existing combined bearings still have defects. For example, the disassembly and assembly of the bearing core still require tools, which is inconvenient. Secondly, combined bearings have insufficient sealing, allowing external dust to easily seep in, causing additional wear and affecting the service life of the bearing core. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a combined bearing housing to solve the problems of inconvenient disassembly and assembly and insufficient sealing of traditional combined bearing housings in the background art.

[0005] This utility model provides the following technical solution: a combined bearing housing, including a main housing sleeve, a bearing core sleeved in the inner cavity of the main housing sleeve, a fixed retaining ring fixedly connected to the back of the bearing core on the inner wall of the main housing sleeve, and a sealing ring threadedly sleeved to the front of the bearing core on the inner wall of the main housing sleeve; the outer ring sidewall of the bearing core is provided with several recessed openings, and a bushing is provided in the inner ring of the bearing core, with the front and rear ends of the bushing passing through the inner cavities of the fixed retaining ring and the sealing ring, respectively; the inner wall of the main housing sleeve is provided with several column holes, each of which is provided with an elastic pin assembly, the output ends of which are embedded in the recessed openings for positioning the outer ring of the bearing core; the interior of the main housing sleeve is provided with several locking grooves communicating with the column holes, each of which is provided with a switch-type locking element, which, when closed, restricts the retraction of the elastic pin assemblies; the sealing ring is disassembled and assembled to control the opening and closing of the switch-type locking elements.

[0006] Furthermore, the elastic pin assembly includes a pin, which is slidably sleeved in the pin hole of the main body seat, and one end of the pin is connected to the inner wall of the pin hole via a spring. The other end of the pin is provided with a ball head, which protrudes outside the pin hole. The side wall of the pin is provided with a slot, and the switch-type locking fastener is embedded in the slot in the closed state to restrict the sliding of the slot.

[0007] Furthermore, the switch-type locking component includes a movable column, which slides within the locking groove of the main body sleeve. The inner wall of the main body sleeve has an expanded diameter annular groove, and the locking groove of the main body sleeve has a groove communicating with the expanded diameter annular groove. A lever is fixedly connected to the side wall of the movable column, passing through the groove and entering the interior of the expanded diameter annular groove. The sealing ring includes an annular plate, and a pressure ring is fixedly connected to the side wall of the annular plate. The side wall of the annular plate is threaded and threadedly fitted onto the inner wall of the main body sleeve. The size of the pressure ring is adapted to the side wall of the expanded diameter annular groove. The pressure ring abuts against the lever, causing the movable column to slide and switch the switch-type locking component to the closed state. The movable column slides in the opposite direction, disengaging from the elastic pin assembly and switching the switch-type locking component to the open state.

[0008] Furthermore, the switch-type locking component also includes a magnetic block one and a magnetic block two. The magnetic block one is fixedly connected to the back end of the movable column, and the magnetic block two is fixedly connected to the inner wall of the locking groove of the main body seat. The magnetic block one and the magnetic block two are magnetically connected to each other.

[0009] Furthermore, a ring-shaped handle is fixedly connected to the back of the ring plate outside the main body seat.

[0010] Furthermore, the fixed retaining ring includes a main ring, the inner wall of which has an annular groove, and a hose is fixedly connected to the inner wall of the annular groove. The side wall of the main seat is provided with an oil inlet that communicates with the annular groove of the main ring. The side of the main ring facing the bearing core is provided with an oil outlet that communicates with the annular groove. One end of the hose is connected to the oil inlet and the other end is connected to the oil outlet. A movable ring is rotatably sleeved in the annular groove of the main ring. Both sides of the movable ring are provided with extrusion wheels for extruding the hose wall. The inner wall of the movable ring is connected to the side wall of the bushing.

[0011] Furthermore, the bushing sidewall is provided with several keyways, and the inner wall of the movable ring is provided with several key teeth.

[0012] The technical effects and advantages of this utility model are as follows: This invention uses a fixed retaining ring and a sealing ring to seal the bearing core within the inner cavity of the main body sleeve, preventing external dust from entering. In addition, an elastic pin assembly and a switch-type locking fastener are set up and linked with the sealing ring to achieve an automatic fixing effect of the bearing core inside the main body sleeve. That is, during the assembly or disassembly of the bearing core, only the sealing ring needs to be turned to complete the disassembly and assembly operations without the need for tools, which greatly improves the convenience of device maintenance.

[0013] In addition, the structure of the fixed retaining ring has been optimized. The fixed retaining ring can be linked with the bearing core. When its inner ring rotates, the fixed retaining ring automatically draws lubricating oil into the inner cavity of the main bearing housing, achieving an automatic oil injection and lubrication effect, making the maintenance process of this combined bearing housing more convenient and faster.

Detailed Implementation

[0016] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] Reference Figures 1-3 This utility model provides a combined bearing housing, including a main housing sleeve 1, a bearing core 4 sleeved in the inner cavity of the main housing sleeve 1, a fixed retaining ring 2 fixedly connected to the back of the bearing core 4 on the inner wall of the main housing sleeve 1, and a sealing ring 3 threadedly sleeved on the front of the bearing core 4 on the inner wall of the main housing sleeve 1; the outer ring sidewall of the bearing core 4 is provided with several recessed openings 41, and the inner ring of the bearing core 4 is provided with a bushing 42, the front and rear ends of the bushing 42 passing through the inner cavities of the fixed retaining ring 2 and the sealing ring 3 respectively; the inner wall of the main housing sleeve 1 is provided with several column holes, each of which is provided with an elastic pin assembly 5, the output end of the elastic pin assembly 5 is embedded in the recessed openings 41 for positioning the outer ring of the bearing core 4; the interior of the main housing sleeve 1 is provided with several locking grooves communicating with the column holes, each of which is provided with a switch-type locking fastener 6, the switch-type locking fastener 6 is closed to restrict the retraction of the elastic pin assembly 5, and the sealing ring 3 is disassembled and assembled to control the opening and closing of the switch-type locking fastener 6.

[0018] When assembling the bearing housing, the bearing core 4 is placed into the inner cavity of the main body sleeve 1. During this process, the bushing 42 of the bearing core 4 passes through the inner cavity of the fixed retaining ring 2, and pressure is applied to the end of the elastic pin assembly 5 to retract it into the post hole. When the bearing core 4 reaches the assembly position, several recesses 41 on its outer ring sidewall align with several post holes on the inner wall of the main body sleeve 1. Several elastic pin assemblies 5 spring back under elastic action, and their ends are embedded in the recesses 41. Then, the sealing ring 3 is screwed into the inner wall of the fixed retaining ring 2. During this process, the positive end of the bushing 42 passes through the inner cavity of the sealing ring 3. The sealing ring 3 also interacts with the switch-type locking element 6, triggering the switch-type locking element 6 from the open state to the closed state. The switch-type locking fastener 6 locks the elastic pin assembly 5, restricting its retraction. Similarly, during disassembly, simply unscrewing the sealing ring 3 automatically releases the switch-type locking fastener 6, canceling the restriction on the elastic pin assembly 5. By pulling the bearing core 4, the elastic pin assembly 5 retracts under force, thus completing the disassembly of the bearing core 4. Through the above structural design, on the one hand, the bearing core 4 can be quickly disassembled and assembled without the need for tools, improving the convenience of maintenance. On the other hand, the fixed retaining ring 2 and the sealing ring 3 can form a seal around the bearing core 4, achieving a good barrier effect against external dust, thus enhancing the durability of the combined bearing housing.

[0019] Reference Figure 4 The elastic pin assembly 5 includes a pin 51, which is slidably sleeved in the pin hole of the main body sleeve 1. One end of the pin 51 is connected to the inner wall of the pin hole via a spring 52. The other end of the pin 51 is provided with a ball head 54, which protrudes out of the pin hole. The side wall of the pin 51 is provided with a slot 53. The switch-type locking fastener 6 is embedded in the slot 53 in the closed state to restrict the sliding of the slot 53.

[0020] When the bearing core 4 enters the inner cavity of the main body sleeve 1, due to the shape characteristics of the ball head 54, the outer ring edge of the bearing core 4 abuts against the circular surface of the ball head 54, which will cause the ball head 54 to have a force to retract into the post hole, thereby driving the slot 53 to slide in the post hole and compressing the spring 52. When the ball head 54 reaches the position of the recess 41, the elasticity of the spring 52 causes the ball head 54 to reset and embed into the recess 41, achieving the effect of pre-fixing the bearing core 4. When the switch-type locking component 6 is in the closed state, its output end is embedded in the slot 53, which can limit the sliding of the slot 53. At this time, the position of the ball head 54 is locked, thereby achieving the effect of fixing the bearing core 4 in the inner cavity of the main body sleeve 1.

[0021] Reference Figure 6The switch-type locking fastener 6 includes a movable post 61, which slides within the locking groove of the main body sleeve 1. The inner wall of the main body sleeve 1 has an enlarged diameter annular groove 11, and the locking groove of the main body sleeve 1 has a groove communicating with the enlarged diameter annular groove 11. A lever 62 is fixedly connected to the side wall of the movable post 61. The lever 62 passes through the groove and enters the interior of the enlarged diameter annular groove 11. The sealing ring 3 includes an annular plate 31, and a pressure ring 32 is fixedly connected to the side wall of the annular plate 31. The side wall of the annular plate 31 is threaded and threadedly fitted into the inner wall of the main body sleeve 1. The size of the pressure ring 32 is adapted to the side wall of the enlarged diameter annular groove 11. The pressure ring 32 abuts against the lever 62 and moves the movable post 61 to slide, causing the switch-type locking fastener 6 to switch to the closed state. The movable post 61 slides in the opposite direction, breaking the connection with the elastic pin assembly 5, causing the switch-type locking fastener 6 to switch to the open state.

[0022] When the sealing ring 3 is turned to connect the ring plate 31 with the inner wall of the main body seat 1, the pressure ring 32 enters the enlarged diameter ring groove 11 and pushes the lever 62. At this time, the lever 62 moves the movable column 61 to slide towards the elastic pin assembly 5 and embeds it into the slot 53 of the elastic pin assembly 5. This causes the switch-type locking fastener 6 to switch to the closed state and lock the elastic pin assembly 5.

[0023] Reference Figure 6 The switch-type locking component 6 also includes a magnetic block 63 and a magnetic block 64. The magnetic block 63 is fixedly connected to the back end of the movable column 61, and the magnetic block 64 is fixedly connected to the inner wall of the locking groove of the main body seat 1. The magnetic blocks 63 and 64 are magnetically connected to each other.

[0024] After the sealing ring 3 is disassembled, magnetic blocks 63 and 64 are set up. Through their magnetic properties, magnetic blocks 63 and 64 can attract each other, so that the movable column 61 can achieve an automatic reset effect, that is, the switch-type locking fastener 6 automatically switches to the open state.

[0025] Reference Figure 6 A ring handle 33 is fixedly connected to the back of the ring plate 31 outside the main body seat 1.

[0026] The ring handle 33 makes it easier to control the rotation of the sealing ring 3 as a whole, making it easier to apply force when assembling or disassembling the sealing ring 3.

[0027] Reference Figure 5The fixed retaining ring 2 includes a main ring 21. The inner wall of the main ring 21 has an annular groove, and a hose 23 is fixedly connected to the inner wall of the annular groove. The side wall of the main seat 1 is provided with an oil inlet 7 that communicates with the annular groove of the main ring 21. The side of the main ring 21 facing the bearing core 4 is provided with an oil outlet 8 that communicates with the annular groove. One end of the hose 23 is connected to the oil inlet 7, and the other end is connected to the oil outlet 8. A movable ring 22 is rotatably sleeved in the annular groove of the main ring 21. Both sides of the movable ring 22 are provided with extrusion wheels 24 for extruding the hose 23 wall. The inner wall of the movable ring 22 is connected to the side wall of the bushing 42.

[0028] The oil inlet 7 connects to an oil tank for storing lubricating oil. When the bearing housing is connected to the shaft, the inner ring of the bearing core 4 rotates, which drives the movable ring 22 to rotate through the bushing 42. When the movable ring 22 rotates, the extrusion wheel 24 can squeeze along the wall of the hose 23. Referring to the principle of a peristaltic pump, when the hose 23 is squeezed by the extrusion wheel 24, a negative pressure suction is generated, which draws the lubricating oil from the oil tank through the oil inlet 7 and outputs it through the oil outlet 8. The lubricating oil enters the inner cavity of the main body sleeve 1 to achieve the effect of lubricating the bearing core 4. Thus, through this structural design, the bearing housing can use rotational power to achieve automatic oil injection and lubrication, improving maintenance convenience.

[0029] Reference Figure 5 The bushing 42 has several keyways 43 on its side wall, and the movable ring 22 has several key teeth 25 on its inner wall.

[0030] As the bushing 42 passes through the inner cavity of the fixed retaining ring 2, several key teeth 25 are respectively engaged into the interior of several keyways 43, thereby forming a connection between the main body ring 21 and the bushing 42, achieving the effect of the bushing 42 rotating to drive the movable ring 22 to rotate.
