Abstract

This invention provides a release bearing assembly, relating to the field of bearing technology, comprising: an inner bearing ring, wherein an annular groove is formed on the outer end surface of the inner bearing ring; an outer bearing ring is provided outside the inner bearing ring; a cage is provided between the outer bearing ring and the inner bearing ring; and rolling balls are rotatably connected to the surface of the cage. In this invention, an elastic retaining strip engages in the groove on the surface of the inner bearing ring, and a locking bolt passes through a connecting hole and is threaded into a threaded hole on the surface of the inner bearing ring. This improves the stability of the dust baffle, which blocks the gap between the inner and outer bearing rings, effectively preventing external dust and impurities from entering the bearing. This solves the problems of existing release bearings, which mostly use only a single-layer baffle for simple shielding, leading to baffle loosening and displacement during long-term high-speed operation, and the lack of a self-lubricating structure in traditional release bearings, making it impossible to achieve automated and precise oil supply when bearing lubricant is insufficient.

Description

Technical Field

[0001] This invention relates to the field of bearing technology, and more particularly to a separable bearing assembly. Background Technology

[0002] Release bearings are fundamental components in automotive transmission systems and engineering machinery transmission mechanisms. They are mainly used to achieve smooth disengagement and engagement of clutches, and play an important role in rotation, load bearing, and drag reduction. Their operational stability, lubrication uniformity, and dust protection performance directly determine the working efficiency and service life of the transmission system.

[0003] Currently, traditional release bearings on the market still have some technical shortcomings in practical applications: First, the existing dustproof structure design of the release bearing is simple, mostly using only a single layer of baffle for simple shielding. The fixing method has poor stability. During long-term high-speed operation, the baffle is prone to loosening and displacement. External dust, mud, water vapor and other impurities can easily enter the bearing through the gap between the inner and outer rings, causing wear and jamming of the balls and raceways. Secondly, traditional release bearings lack a self-lubricating structure. When the bearing lubricant is insufficient, it cannot achieve automated and precise oil supply. Lubricant tends to flood into the bearing in large quantities at once, failing to achieve uniform and slow-release lubrication. This results in localized over-lubrication and localized under-lubrication, leading to uneven bearing wear and a significant decrease in operational stability over long-term operation. Summary of the Invention

[0004] This invention relates to release bearing assemblies, and solves the problems of existing release bearings having simple dustproof structures, mostly using only a single-layer baffle for simple shielding, which easily leads to baffle loosening and displacement during long-term high-speed operation. In addition, traditional release bearings lack self-lubricating structures, and cannot achieve automated and precise oil supply when bearing lubricating oil is insufficient. Lubricating oil can easily flood into the bearing at one time, failing to achieve uniform and slow-release lubrication, resulting in local over-lubrication and local under-lubrication, and uneven bearing wear under long-term operation.

[0005] The present invention provides a release bearing assembly, specifically comprising: a release bearing assembly, characterized in that it includes: a bearing inner ring; The outer circumference of the inner ring of the bearing has an arc-shaped structure in the middle, and a circular groove is provided on the outer end surface of the inner ring of the bearing. The bearing inner ring is provided with an outer ring outside the bearing outer ring. The inner end surface of the bearing outer ring has an arc-shaped structure. A cage is provided between the bearing outer ring and the bearing inner ring. Rolling balls are rotatably connected to the surface of the cage. The bearing outer ring has an injection hole inside, and the front end of the injection hole has an adjustment cavity. The adjustment cavity has a fixing ring inside, and two connecting rods are symmetrically arranged outside the fixing ring. The outer end face of the connecting rods is fixedly connected to the inner wall of the adjustment cavity. A monitor is fixedly installed on the inner end face of the bearing outer ring. The control cavity is slidably connected to a circular plate-shaped cover. A return spring is fixedly installed on the inner end face of the cover. The end face of the return spring is fixedly connected to the fixed ring. An oil reservoir is fixedly installed on the outer end face of the outer ring of the bearing. The outlet end of the oil reservoir coincides with the inlet end of the filling hole. A controller, a micro air pump, and an exhaust pipe are fixedly installed on the upper end face of the oil reservoir. The controller and the monitor are electrically connected. The bearing inner ring is provided with a dust baffle plate, and an elastic retaining strip is fixedly installed on the inner end face of the dust baffle plate. The elastic retaining strip is engaged in the retaining groove on the outer end surface of the bearing inner ring.

[0006] Furthermore, the outer end face of the bearing inner ring is provided with a threaded hole in an annular shape, and the surface of the dust baffle is provided with a connecting hole in an annular shape. The bolt passes through the connecting hole on the surface of the dust baffle and is threaded into the threaded hole on the surface of the bearing inner ring.

[0007] Furthermore, the inner end face of the dust baffle is provided with three grooves, and the dust baffle is located at the outer end of the gap between the inner ring and the outer ring of the bearing.

[0008] Furthermore, the vertical end of the filling hole is provided with a slow-release cavity, which is a spherical structure. The slow-release cavity contains a slow-release ball, and the outer end face of the slow-release ball is provided with a drainage groove.

[0009] Furthermore, the inner end surface of the control cavity is provided with a limit groove in an annular shape, and limit blocks are uniformly installed on the outer circumference of the cover plate. The limit blocks are slidably connected in the limit groove on the inner end surface of the control cavity.

[0010] Furthermore, the controller is located between the exhaust pipe and the micro air pump, and the controller and the micro air pump are electrically connected.

[0011] Furthermore, the surface of the exhaust pipe is provided with an electronically controlled switch, which is electrically connected to the controller.

[0012] Furthermore, a connecting pipe is fixedly installed on the upper end face of the oil storage box, and a protective cover is provided on the upper end face of the connecting pipe.

[0013] This invention provides a release bearing assembly, which has the following beneficial effects: 1. The elastic retaining strip engages with the groove on the surface of the bearing inner ring, fixing the dust baffle to the outside of the bearing inner ring. Simultaneously, the locking bolt passes through the connecting hole and is threaded into the threaded hole on the surface of the bearing inner ring, improving the stability of the dust baffle outside the bearing inner ring. The dust baffle blocks the gap between the bearing inner and outer rings, effectively preventing external dust and impurities from entering the bearing and ensuring its normal operation. Three grooves are provided on the inner end face of the dust baffle, forming a buffer cavity. This reduces friction and pressure between the dust baffle and bearing components, and slightly guides airflow in the gap, preventing negative pressure from adsorbing dust and further enhancing the dustproof effect.

[0014] 2. A monitor is installed on the inner end face of the outer ring of the bearing. The monitor can monitor the lubrication status inside the bearing. When the lubricating oil is insufficient, the monitor can send a signal to the controller. After receiving the signal, the controller will send a command to the micro air pump. After the micro air pump starts, it will inflate the oil reservoir. After the air pressure inside the oil reservoir increases, the lubricating oil inside the oil reservoir will flow into the filling hole.

[0015] 3. The vertical end of the filling hole is equipped with a spherical slow-release chamber. The slow-release ball is installed inside the slow-release chamber. The drainage groove on the surface of the slow-release ball can limit and guide the flow of lubricating oil, preventing a large amount of lubricating oil from rushing into the bearing at one time, so as to realize the slow-release supply of lubricating oil and ensure lubrication uniformity.

[0016] 4. When the monitor detects that the lubricating oil has met the standard, the monitor can send a signal to the controller. The controller will stop the micro air pump and send a command to the electronic control switch on the surface of the exhaust pipe. After the electronic control switch is opened, the high-pressure gas inside the oil reservoir will be discharged through the exhaust pipe. After the high-pressure gas inside the oil reservoir is released, the cover will move outward under the action of the return spring, blocking the filling hole, pausing the oil supply, and closing the oil supply passage to achieve intermittent precise lubrication.

Detailed Implementation

[0021] Example 1: Please refer to Figures 1 to 9 : The present invention proposes a separable bearing assembly, comprising: a bearing inner ring 1, the middle part of the outer circumference of the bearing inner ring 1 having an arc-shaped structure, an annular groove 101 formed on the outer end surface of the bearing inner ring 1, a dust baffle 8 provided on the outside of the bearing inner ring 1, and an elastic retaining strip 801 fixedly installed on the inner end face of the dust baffle 8, the elastic retaining strip 801 being engaged in the groove 101 on the outer end surface of the bearing inner ring 1; The bearing inner ring 1 is provided with an outer ring 2. The inner end surface of the bearing outer ring 2 is an arc-shaped structure. A cage 9 is provided between the bearing outer ring 2 and the bearing inner ring 1. A ball 901 is rotatably connected to the surface of the cage 9. The ball 901 rolls along the arc-shaped raceway of the inner and outer rings, converting sliding friction into rolling friction and greatly reducing the bearing's operating resistance. The bearing outer ring 2 has an injection hole 201 inside. The front end of the injection hole 201 has an adjustment cavity 4. The adjustment cavity 4 has a fixing ring 5 inside. Two connecting rods 501 are symmetrically arranged outside the fixing ring 5. The outer end face of the connecting rod 501 is fixedly connected to the inner wall of the adjustment cavity 4. A monitor 202 is fixedly installed on the inner end face of the bearing outer ring 2. The control cavity 4 is slidably connected to a circular plate-shaped cover 6. A return spring 602 is fixedly installed on the inner end face of the cover 6, and the end face of the return spring 602 is fixedly connected to the fixing ring 5. An oil reservoir 7 is fixedly installed on the outer end face of the outer ring 2 of the bearing. The outlet end of the oil reservoir 7 coincides with the inlet end of the filling hole 201. A controller 702, a micro air pump 703, and an exhaust pipe 704 are fixedly installed on the upper end face of the oil reservoir 7. The bearing inner ring 1 has a threaded hole on its outer end face in an annular shape, and the dust baffle 8 has a connecting hole 803 on its surface in an annular shape. Bolts pass through the connecting hole 803 on the surface of the dust baffle 8 and are threaded into the threaded hole on the surface of the bearing inner ring 1. The dust baffle 8 has three grooves 802 on its inner end face. The dust baffle 8 is located at the outer end of the gap between the bearing inner ring 1 and the bearing outer ring 2. In use, the dust baffle 8 has an elastic retaining strip 801 on its inner end face. Workers can engage the elastic retaining strip 801 in the retaining groove 101 on the surface of the bearing inner ring 1 to fix the dust baffle 8 to the outside of the bearing inner ring 1. The bearing inner ring 1 has a threaded hole on its surface, and the dust baffle 8 has a connecting hole 803 on its surface in an annular shape. Locking bolts can pass through the connecting hole 803 and be threaded into the threaded hole on the surface of the bearing inner ring 1, which can improve the stability of the dust baffle 8 outside the bearing inner ring 1.

[0022] The filling hole 201 has a release chamber 2011 at its vertical end. The release chamber 2011 is a spherical structure and contains a release ball 3. The outer end face of the release ball 3 has a drainage groove 301. In use, the release chamber 2011 with a spherical structure is provided at the vertical end of the filling hole 201. The release ball 3 is assembled inside the release chamber 2011. The drainage groove 301 on the surface of the release ball 3 can limit and guide the flow of lubricating oil, preventing a large amount of lubricating oil from rushing into the bearing at one time, realizing the slow release supply of lubricating oil and ensuring lubrication uniformity.

[0023] The inner end surface of the control cavity 4 has a ring-shaped limiting groove 401, and the outer circumference of the cover plate 6 is uniformly equipped with limiting blocks 601. The limiting blocks 601 are slidably connected in the limiting groove 401 on the inner end surface of the control cavity 4. When the cover plate 6 moves back and forth, the limiting blocks 601 are slidably connected in the limiting groove 401, so that the cover plate 6 will not wobble left and right when it moves back and forth.

[0024] The oil reservoir 7 is fixedly installed with a connecting pipe 701 on its upper end face. The upper end face of the connecting pipe 701 is provided with a protective cover. During use, workers can add lubricating oil into the oil reservoir 7 through the connecting pipe 701.

[0025] Example 2, based on Example 1, such as Figures 1-9As shown, the controller 702 is located between the exhaust pipe 704 and the micro air pump 703. The controller 702 is electrically connected to the micro air pump 703 and to the monitor 202. An electric control switch 7041 is provided on the surface of the exhaust pipe 704 and is electrically connected to the controller 702.

[0026] The technical effects of adopting the above solution are as follows: A monitor 202 is provided on the inner end face of the outer ring 2 of the bearing. The monitor 202 can monitor the lubrication status inside the bearing. When the lubricating oil is insufficient, the monitor 202 can send a signal to the controller 702. After receiving the signal, the controller 702 will send a command to the micro air pump 703. After the micro air pump 703 starts, it will inflate the oil reservoir 7. After the air pressure inside the oil reservoir 7 increases, the lubricating oil inside the oil reservoir 7 will flow into the filling hole 201. When the monitor 202 detects that the lubricating oil has reached the standard... When necessary, the monitor 202 can send a signal to the controller 702, which will stop the micro air pump 703 from running. The controller 702 will also send a command to the electronic control switch 7041 on the surface of the exhaust pipe 704. After the electronic control switch 7041 is opened, the high-pressure gas inside the oil reservoir 7 will be discharged through the exhaust pipe 704. After the high-pressure gas inside the oil reservoir 7 is released, under the action of the return spring 602, the cover plate 6 will move outward to block the filling hole 201, suspend the oil supply, close the oil supply passage, and achieve intermittent precise lubrication.

[0027] The working principle of this embodiment: In this invention, a cage 9 is provided between the inner ring 1 and the outer ring 2 of the bearing to evenly separate the rolling balls 901 and prevent them from rubbing and colliding with each other. The rolling balls 901 are rotatably connected to the surface of the cage 9, and can rotate freely on the surface of the cage 9. The inner ring 1 and the outer ring 2 of the bearing rotate relative to each other, and the rolling balls 901 roll along the arc-shaped raceways of the inner and outer rings, converting sliding friction into rolling friction, which greatly reduces the bearing's operating resistance. A groove 101 is provided on the outside of the inner ring 1, and an elastic strip 801 is provided on the inner end face of the dust baffle 8. Workers can engage the elastic strip 801 in the groove 101 on the surface of the inner ring 1 to fix the dust baffle 8 to the outside of the inner ring 1. The surface of the inner ring 1 is provided with threaded holes, and the dust baffle 8... The surface of the dust baffle 8 has a ring-shaped connecting hole 803, through which a locking bolt can be passed and threaded into the threaded hole on the surface of the inner ring 1 of the bearing. This improves the stability of the dust baffle 8 outside the inner ring 1 of the bearing. The dust baffle 8 blocks the gap between the inner ring 1 and the outer ring 2 of the bearing, effectively preventing external dust and impurities from entering the bearing and ensuring normal operation of the bearing. In addition, the inner end face of the dust baffle 8 has three grooves 802, which can form a buffer cavity. This reduces the friction and compression between the dust baffle 8 and the bearing components, and slightly guides the airflow in the gap, preventing negative pressure from adsorbing dust and further improving the dustproof effect. The outer ring 2 of the bearing has a filling hole 201 inside. The outlet end of the outer end of the oil reservoir 7 coincides with the inlet end of the filling hole 201, storing oil. The lubricating oil inside the oil reservoir 7 can enter between the inner ring 1 and the outer ring 2 of the bearing through the filling hole 201. A connecting pipe 701 is fixedly installed on the upper end face of the oil reservoir 7, allowing workers to add lubricating oil to the oil reservoir 7 through the connecting pipe 701. A monitor 202 is installed on the inner end face of the outer ring 2 of the bearing. The monitor 202 can monitor the lubrication status inside the bearing. When the lubricating oil is insufficient, the monitor 202 can send a signal to the controller 702. After receiving the signal, the controller 702 will send a command to the micro air pump 703. After the micro air pump 703 starts, it will inflate the oil reservoir 7. After the air pressure inside the oil reservoir 7 increases, the lubricating oil inside the oil reservoir 7 will flow into the filling hole 201. The filling hole 201 is horizontally divided. A regulating chamber 4 is provided. The ends of the connecting rods 501 at both ends of the fixing ring 5 are fixedly connected to the inner wall of the regulating chamber 4. A return spring 602 is provided between the cover plate 6 and the fixing ring 5. After the micro air pump 703 is started, the lubricating oil can push the cover plate 6 inward, thereby compressing the return spring 602. At this time, the lubricating oil will enter the filling hole 201 through the gap between the cover plate 6 and the inner wall of the regulating chamber 4. The limiting block 601 at the outer end of the cover plate 6 is slidably connected in the limiting groove 401, so that the cover plate 6 will not wobble when moving back and forth. The vertical part of the filling hole 201 is provided with a spherical slow-release chamber 2011. The slow-release ball 3 is assembled inside the slow-release chamber 2011. The drainage groove 301 on the surface of the slow-release ball 3 can limit and guide the flow of lubricating oil.To prevent a large influx of lubricating oil into the bearing at once, a slow-release supply of lubricating oil is achieved to ensure uniform lubrication. When the monitor 202 detects that the lubricating oil level meets the standard, the monitor 202 sends a signal to the controller 702. The controller 702 then stops the micro air pump 703 and sends a command to the electronic switch 7041 on the surface of the exhaust pipe 704. After the electronic switch 7041 opens, the high-pressure gas inside the oil reservoir 7 is discharged through the exhaust pipe 704. After the high-pressure gas inside the oil reservoir 7 is released, under the action of the return spring 602, the cover plate 6 moves outward, blocking the filling hole 201, pausing the oil supply, and closing the oil supply passage to achieve intermittent and precise lubrication.
