Description

Technical Field

[0001] The present invention relates to the technical field of bearings, and specifically to a locking collar device that is portable and quickly detachable. Background Technique

[0002] Currently, in the field of mechanical transmission, the fixation of bearings and transmission shafts is usually achieved by a locking collar device. Traditional locking collar devices mainly rely on threaded connections or wedge structures for fixation, and have the following technical defects.

[0003] Chinese Patent Publication No. CN106944972A discloses a detachable locking collar, which includes a locking inner liner, a locking collar, and a slot. A narrow groove is provided on one side of the locking inner liner, and a wide groove is arranged below the narrow groove. The wide groove communicates with the narrow groove. A locking collar is threadedly connected to one side of the locking inner liner near the bottom end. A notch is provided on the outer surface of the locking collar. There are a total of four groups of notches, and the four groups of notches are evenly distributed in a circular shape on the outer side of the locking collar. A bolt hole is provided on one side of the locking collar, and a fastening screw is threadedly connected to the center of the bolt hole. A protective gasket is welded to one side of the fastening screw. A slot is provided on the outer surface of the locking inner liner. This detachable locking collar is provided with a movable pin that can be withdrawn on the device, and the height of the movable pin is higher than the height of the locking inner liner. After use, the movable pin can be pulled out, and then the locking inner liner can be easily taken out. It is detachable, convenient, and fast.

[0004] Chinese Patent Publication No. CN106704388A discloses a bearing locking collar, which relates to the technical field of bearings. The bearing locking collar includes an inner sleeve, an outer sleeve, an oil nozzle, and a plug. The inner hole of the outer sleeve is matched with the outer circle of the inner sleeve. An annular cavity is provided between the mating surfaces of the inner sleeve and the outer sleeve. The inner sleeve and the outer sleeve are fixedly connected. There is a clearance fit between the inner hole of the inner sleeve and the installation shaft, and there is a clearance fit between the outer circle of the outer sleeve and the inner hole of the bearing. The oil nozzle communicates with the annular cavity. Hydraulic oil is injected into the annular cavity through the oil nozzle. The inner sleeve and the outer sleeve undergo elastic deformation under the pressure of the hydraulic oil, and the clearance fit between the locking collar and the installation shaft and the bearing becomes an interference fit; the plug is used to release the hydraulic oil inside the annular cavity. The advantages of the present invention are that the bearing installation does not require heating, the strength of the shaft is improved, the inner hole of the bearing is not easily abraded, and it is not necessary to measure the remaining radial clearance of the bearing. When disassembling, only the pressure inside the locking collar needs to be released, which saves time and effort.

[0005] However, the existing devices have the following problems:

[0006] The stability of the support and limit of the adapter sleeve for the bearing also needs to be improved urgently. Most of the existing adapter sleeves are of an integral structure. Under complex working conditions, such as when the equipment runs at high speed, starts and stops frequently, or bears large vibrations, it is difficult to always maintain stable support for the bearing, which easily leads to bearing displacement and loosening, thereby affecting the overall performance of the equipment and even causing serious safety accidents. Although some adapter sleeves are fixed by bolts and other methods, during long-term use, the bolts are prone to loosen due to vibration and cannot continuously provide reliable limiting effect for the bearing. In terms of operation convenience, traditional adapter sleeve devices almost rely on professional tools, such as wrenches and sockets, during installation and disassembly. In some special working environments, such as inside mechanical equipment with narrow space and field operation sites, these tools may be difficult to use, or when the staff does not carry suitable tools, the installation and disassembly of the adapter sleeve will be in trouble, greatly restricting the smooth progress of the work.

[0023] (III) Beneficial effects

[0024] Compared with the prior art, the present invention provides a portable and quickly detachable locking sleeve device, which has the following beneficial effects:

[0025] 1. For this portable and quickly detachable locking sleeve device, through the cooperation of four guiding grooves and four guiding blocks, and by virtue of the four guiding grooves being arranged in an obliquely outward shape, when the four guiding blocks slide inside the guiding grooves, the end of the support cylinder can be opened outward or tightened inward by means of the reaction force. Therefore, when installing an eccentric bearing, the guiding blocks can be rotated forward to tighten the end of the support cylinder, facilitating the staff to install the eccentric bearing.

Thus, when the two locking half-rings are docked with each other to support the eccentric bearing, the push ring and the clamping blocks can be used to clamp and fix the locking half-rings, ensuring that the two locking half-rings will not separate. At the same time, the compression spring can continuously apply pressure to the push ring, thereby ensuring that the two locking half-rings can stably support the eccentric bearing. And during the disassembly process, by applying a thrust to the push ring to overcome the resistance of the compression spring and slide, after the push ring and the locking half-rings are relatively separated, the two locking half-rings can be directly separated from each other, facilitating the staff to directly remove the eccentric bearing without too much operation, thus improving the operation convenience of the device.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 to 8, an embodiment of the present invention provides a locking collar, which is applied to the scenario of installing a bearing on the surface of a transmission shaft without using tools. In this embodiment, the structure of the locking collar is improved to make it have the advantages of quick installation and disassembly without tools and stable operation. Specifically, taking the installation of a bearing as an example, so as a preferred solution in this embodiment, the locking collar is specifically a portable and quickly detachable locking collar device, which can install a bearing on the surface of a transmission shaft without using tools.

[0039] Please refer to Figures 1 to 8 , the present invention provides a technical solution: a portable and quickly detachable locking collar device, which is applied to the scenario of installing a bearing on the surface of a transmission shaft without using tools.

[0040] It includes a support mechanism 1, a locking mechanism 4, a limiting mechanism 5 and a blocking mechanism 7, wherein:

[0041] The support mechanism 1 includes a support cylinder 101 and four guide grooves 103. The four guide grooves 103 are respectively opened at the end of the support cylinder 101. The support cylinder 101 serves as the core load-bearing component of the entire device, providing a basic platform for the installation of other components, ensuring that each component can be orderly combined and work together. The guide grooves 103 are opened at the end of the support cylinder 101 in a unique shape that slopes outward, and cooperate with the guide block 706 in the blocking mechanism 7. During the rotation of the guide block 706, using the principle of reaction force, the opening and closing of the end of the support cylinder 101 are precisely controlled. When installing the eccentric bearing 3, rotate the guide block 706 forward, and the end of the support cylinder 101 contracts inward, creating precise adaptation conditions for the installation of the eccentric bearing 3, facilitating the staff to accurately install the eccentric bearing 3. When disassembling, rotate the guide block 706 backward, and the end of the support cylinder 101 expands outward, easily realizing separation from the transmission shaft, significantly improving the efficiency and convenience of installation and disassembly;

[0042] The locking mechanism 4 includes two locking half-rings 401 and a plurality of slots 406. The two locking half-rings 401 are butt-jointed and fixed to the outer wall of the support cylinder 101. The plurality of slots 406 are respectively arranged in an annular array on the outer walls of the two locking half-rings 401. The two locking half-rings 401 are butt-jointed and fixed to the outer wall of the support cylinder 101, providing the main support and limit functions for the eccentric bearing 3. It is a key component to ensure the stable operation of the eccentric bearing 3. Its solid structure can withstand large external forces, ensuring that the eccentric bearing 3 will not displace or loosen under complex working conditions. The slots 406 are arranged in an annular array on the outer walls of the two locking half-rings 401 and cooperate with the push ring 503 and the clamping block 504 in the limiting mechanism 5. When the two locking half-rings 401 are butt-jointed and support the eccentric bearing 3, the clamping block 504 on the push ring 503 is inserted into the slot 406 to realize the clamping and fixing of the locking half-ring 401 and prevent it from separating. At the same time, under the action of the compression spring 502, it is ensured that the two locking half-rings 401 can stably support the eccentric bearing 3;

[0043] The limiting mechanism 5 includes a limiting ring 501, a compression spring 502, a push ring 503 and a plurality of clamping blocks 504. The limiting ring 501 is slidably connected to the outer wall of the support cylinder 101. One end of the compression spring 502 is fixedly connected to the outer wall of the limiting ring 501, and the other end of the compression spring 502 is fixedly connected to the outer wall of the push ring 503. The plurality of clamping blocks 504 are respectively fixedly installed on the outer wall of the push ring 503. The outer wall of the clamping block 504 is inserted into the inner wall of the slot 406. By slidably connecting the limiting ring 501 to the outer wall of the support cylinder 101, as the installation carrier of the compression spring 502 and the push ring 503, it provides guidance and support for the movement of the push ring 503, ensuring that the push ring 503 can stably slide on the outer wall of the support cylinder 101, realizing the clamping and loosening operations of the locking half-ring 401. One end of the compression spring 502 is fixedly connected to the outer wall of the limiting ring 501, and the other end is fixedly connected to the outer wall of the push ring 503. The compression spring 502 continuously applies a stable pressure to the push ring 503, so that the clamping block 504 on the push ring 503 always maintains a clamped state with the slot 406, ensuring that the two locking half-rings 401 will not separate when supporting the eccentric bearing 3, enhancing the stability and reliability of the device. Under the action of the compression spring 502, the push ring 503 drives the clamping block 504 to slide on the outer wall of the support cylinder 101. When it is necessary to clamp the locking half-ring 401, the push ring 503 pushes the clamping block 504 to insert into the slot 406. During the disassembly process, the push ring 503 is pushed against the resistance of the compression spring 502, so that the clamping block 504 is separated from the slot 406, realizing the easy separation of the two locking half-rings 401 and improving the operation convenience. The clamping block 504 is fixedly installed on the outer wall of the push ring 503 and closely cooperates with the slot 406 of the locking mechanism 4. After the clamping block 504 is inserted into the slot 406, the clamping and fixing of the locking half-ring 401 is realized, preventing it from separating, and ensuring that the two locking half-rings 401 can stably support the eccentric bearing 3. It is one of the key components to ensure the stability of the device;

[0044] The blocking mechanism 7 includes a blocking ring 701, four blocking rods 703 and four guiding blocks 706. The inner wall of the blocking ring 701 is threadedly connected to one end of the outer wall of the support cylinder 101 away from the guiding groove 103. The four blocking rods 703 are respectively rotatably connected to the outer wall of the support cylinder 101. The four guiding blocks 706 are respectively fixedly installed on the outer wall of the blocking ring 701 and correspond to the four guiding grooves 103. The inner wall of the blocking ring 701 is threadedly connected to one end of the outer wall of the support cylinder 101 away from the guiding groove 103. By rotating the blocking ring 701, the guiding block 706 can be driven to move in the guiding groove 103, so as to realize the opening and closing of the end of the support cylinder 101, accurately control the connection and separation between the support cylinder 101 and the transmission shaft, and is one of the key components to realize the convenient installation and disassembly of the device. The blocking rod 703 is rotatably connected to the inner side wall of the installation groove 702, and the four blocking rods 703 are respectively arranged in two directions. When tightening or loosening the blocking ring 701, the staff can use the blocking rods 703 in different directions to exert force according to the actual situation, and can easily complete the operation without the help of additional professional tools, significantly improving the convenience of the operation. The guiding block 706 is fixedly installed on the outer wall of the blocking ring 701 and accurately corresponds to the guiding groove 103 at the end of the support cylinder 101. When the blocking ring 701 rotates, the guiding block 706 moves in the guiding groove 103, and the reaction force is used to open the end of the support cylinder 101 outward or tighten it inward, realizing the connection and separation between the support cylinder 101 and the transmission shaft, and is one of the key components to realize the convenient installation and disassembly of the device.

[0045] The support mechanism 1 further includes four hollow slots 102. The four hollow slots 103 are respectively opened on the outer wall of the support cylinder 101 and are located between the four guiding grooves 102. By opening the hollow slots 102 on the outer wall of the support cylinder 101 and being located between the guiding grooves 103, the overall weight of the support cylinder 101 is effectively reduced. At the same time, during the opening and closing process of the end of the support cylinder 101, it helps the support cylinder 101 to deform more flexibly, improving the smoothness and flexibility of the operation, and enabling the device to operate stably under complex working conditions.

[0046] On one side of the inner wall of the support cylinder 101, a first compensation mechanism 2 is provided. The first compensation mechanism 2 includes four positioning grooves 201, four positioning plates 202 and four rubber pads 203. The four positioning grooves 201 are respectively opened on one side of the inner wall of the support cylinder 101. The four positioning plates 202 are respectively slidably connected to the inner walls of the four positioning grooves 201. The four rubber pads 203 are respectively fixedly installed on the outer walls of the four positioning plates 202. The positioning grooves 201 provide sliding tracks for the positioning plates 202, ensuring that the positioning plates 202 can select positioning plates 202 and rubber pads 203 with different sizes and thicknesses according to the diameter change of the transmission shaft, so that the rubber pads 203 can closely fit the surface of the transmission shaft, realizing effective compensation for the connection between the transmission shaft and the support cylinder 101, improving the stability and reliability of the connection. The rubber pads 203 are fixed on the outer walls of the positioning plates 202. On the one hand, they play a buffering role, reducing the rigid contact between the support cylinder 101 and the transmission shaft and reducing wear. On the other hand, they enhance the friction force with the surface of the transmission shaft, ensuring that the support cylinder 101 and the transmission shaft can maintain a tight connection under different working conditions, expanding the application range of the device.

[0047] An eccentric bearing 3 is sleeved on the outer surface of the support cylinder 101. One side of the outer surface of the eccentric bearing 3 abuts against the outer walls of two locking half rings 401. By being sleeved on the outer surface of the support cylinder 101 and with one side of its outer surface abutting against the outer walls of two locking half rings 401, in mechanical transmission, the eccentric bearing 3 can realize eccentric motion to meet the specific requirements of some special mechanical structures for eccentric motion.

[0048] The locking mechanism 4 further includes two limit blocks 402, two limit holes 403, multiple snap rings 404 and multiple card slots 405. The end parts of the two limit blocks 402 are respectively fixedly installed on the outer wall of one of the locking half-rings 401. The two limit holes 403 are respectively opened on the outer wall of the other locking half-ring 401. The inner walls of the two limit holes 403 are inserted into the outer walls of the two limit blocks 402.

Multiple card slots 405 are all opened in the middle of the outer surface of the support cylinder 101 and are adapted to the multiple snap rings 404. The snap rings 404 are fixedly installed on the inner walls of the two locking half-rings 401 and are mutually adapted to the card slots 405 opened in the middle of the outer surface of the support cylinder 101. The cooperation between the snap rings 404 and the card slots 405 further strengthens the connection stability between the locking half-ring 401 and the support cylinder 101, preventing the locking half-ring 401 from displacing or loosening during the operation of the device, improving the reliability of the entire device. The card slots 405 are opened in the middle of the outer surface of the support cylinder 101 and are in close cooperation with the snap rings 404, enhancing the connection strength between the locking half-ring 401 and the support cylinder 101, ensuring that the locking half-ring 401 can stably support the eccentric bearing 3 under various working conditions and guaranteeing the normal operation of the device. The slot 406 is arranged in an annular array on the outer walls of the two locking half-rings 401 and works in coordination with the push ring 503 and the clamping block 504 in the limiting mechanism 5. When the two locking half-rings 401 are butted and support the eccentric bearing 3, the clamping block 504 on the push ring 503 is inserted into the slot 406 to realize the clamping and fixing of the locking half-ring 401 and prevent it from separating. At the same time, under the action of the compression spring 502, it is ensured that the two locking half-rings 401 can stably support the eccentric bearing 3.

[0049] The limiting mechanism 5 further includes four sliders 505 and four chutes 506. The four sliders 505 are respectively fixedly installed on the inner side wall of the limiting ring 501. The four chutes 506 are respectively opened on the outer wall of the support cylinder 101. The inner walls of the four chutes 506 are respectively slidably connected to the inner walls of the four sliders 505. The sliders 505 are fixedly installed on the inner side wall of the limiting ring 501 and are mutually adapted to the chutes 506 opened on the outer wall of the support cylinder 101. The sliders 505 slide in the chutes 506, making the sliding of the limiting ring 501 on the outer wall of the support cylinder 101 smoother, ensuring the stability of the push ring 503 and the clamping block 504 during the movement, and further ensuring that the clamping effect on the locking half-ring 401 is not affected, improving the overall reliability of the device. The chutes 506 are opened on the outer wall of the support cylinder 101 and are adapted to the sliders 505, providing accurate guidance for the sliding of the limiting ring 501, ensuring that the limiting ring 501 can slide smoothly and steadily on the outer wall of the support cylinder 101, guaranteeing the movement stability of the push ring 503 and the clamping block 504, and thus improving the overall performance of the device.

[0050] On the other side of the inner wall of the support cylinder 101, a second compensation mechanism 6 is provided. The second compensation mechanism 6 includes four fixing grooves 601, two fixing plates 602 and two gaskets 603. The four fixing grooves 601 are respectively opened on the other side of the inner wall of the support cylinder 101. The two fixing plates 602 are respectively slidably connected to the inner side walls of the four fixing grooves 601. The two gaskets 603 are respectively fixedly installed on the outer walls of the two fixing plates 602. The fixing grooves 601 provide sliding tracks for the fixing plates 602, enabling the fixing plates 602 to slide in the fixing grooves 601 according to the specific conditions of the transmission shaft, so as to realize further compensation and adjustment of the connection between the support cylinder 101 and the transmission shaft. The fixing plates 602 are slidably connected to the inner side walls of the fixing grooves 601 and are adjusted in position according to the actual conditions of the transmission shaft, so that the gaskets 603 can be in close contact with the surface of the transmission shaft, further enhancing the tightness and stability of the connection between the support cylinder 101 and the transmission shaft, ensuring that the device can operate stably under different working conditions. The gaskets 603 are installed on the outer walls of the fixing plates 602 and are in contact with the surface of the transmission shaft, which can not only buffer the acting force between the support cylinder 101 and the transmission shaft, reduce wear, but also enhance the stability of the connection, improving the adaptability and reliability of the device.

[0051] The blocking mechanism 7 further includes four mounting grooves 702. The four mounting grooves 702 are respectively opened on the outer wall of the blocking ring 701. The end parts of the four blocking rods 703 are respectively rotatably connected to the inner side walls of the four mounting grooves 702. By opening the mounting grooves 702 on the outer wall of the blocking ring 701, a rotational mounting position is provided for the blocking rods 703, ensuring that the blocking rods 703 can rotate flexibly in the mounting grooves 702 to realize force application operations in different directions.

[0052] The blocking mechanism 7 further includes four magnets 704 and four iron sheets 705. The four magnets 704 are respectively fixedly installed on the inner bottom walls of the four mounting grooves 702. The four iron sheets 705 are respectively fixedly connected to the outer surfaces of the four blocking rods 703. The outer surfaces of the magnets 704 are adsorbed to the outer surfaces of the iron sheets 705. By fixedly installing the magnets 704 on the inner bottom walls of the mounting grooves 702 and adsorbing them to the iron sheets 705 connected to the outer surfaces of the blocking rods 703, when the blocking rods 703 are not in use, the blocking rods 703 are firmly fixed in the mounting grooves 702 to prevent them from shaking and interfering with the normal operation of the device. When the blocking rods 703 need to be used, the blocking rods 703 can be conveniently rotated for operation, improving the practicality of the device and the convenience of operation.

Install the first compensation mechanism 2: Insert the four positioning plates 202 into the four positioning grooves 201 on one side of the inner wall of the support cylinder 101 respectively, with the rubber pads 203 facing the inside of the support cylinder 101, thus completing the installation of the first compensation mechanism 2. This mechanism can adapt to drive shafts of different diameters and improve the connection stability.

[0055] 2. Install the second compensation mechanism 6: Install the two fixing plates 602 in the four fixing grooves 601 on the other side of the inner wall of the support cylinder 101 respectively, with the gaskets 603 also facing the inside of the support cylinder 101, which is used to further compensate and adjust the connection between the support cylinder 101 and the drive shaft and enhance the stability.

[0056] 3. Install the eccentric bearing 3: Rotate the guiding and rotating blocking ring 701 forward to drive the guiding block 706 to move in the guiding groove 103, and use the reaction force to make the end of the support cylinder 101 contract inward. At this time, install the eccentric bearing 3 on the support cylinder 101 and adjust the position.

[0057] 4. Install the locking mechanism 4: Align the limiting block 402 of one locking half-ring 401 with the limiting hole 403 of the other locking half-ring 401, so that the two locking half-rings 401 are butted and fixed on the outer wall of the support cylinder 101. At this time, the clamping ring 404 on the inner wall of the locking half-ring 401 is adapted to the clamping groove 405 in the middle of the outer surface of the support cylinder 101 to complete the preliminary fixation. At the same time, a plurality of slots 406 are distributed in an annular array on the outer walls of the two locking half-rings 401, waiting to cooperate with the limiting mechanism 5.

[0058] 5. Install the limiting mechanism 5: Connect the limiting ring 501 to the outer wall of the support cylinder 101 through the cooperation of the four sliders 505 on the inner side wall and the four sliding grooves 506 on the outer wall of the support cylinder 101, so that the limiting ring 501 can be slidably connected to the outer wall of the support cylinder 101. Push the push ring 503, and under the action of the compression spring 502, the push ring 503 drives the clamping block 504 to move and insert into the slot 406 on the outer wall of the locking half-ring 401, realizing the clamping and fixing of the locking half-ring 401, thereby stably supporting the bearing.

[0059] 6. Install the blocking mechanism 7: Fix the four guiding blocks 706 on the outer wall of the blocking ring 701, then connect the blocking ring 701 to the outer wall of the support cylinder 101 at the end far from the guiding groove 103 through the internal thread on the inner wall. Then, rotatably connect the four blocking rods 703 to the outer wall of the blocking ring 701 through the installation grooves 702 respectively, and at the same time make the magnet 704 and the iron sheet 705 adsorb each other to fix the blocking rods 703.

[0060] Disassembly operation steps

[0061] 1. Release the limit mechanism 5: Overcome the resistance of the compression spring 502, push the push ring 503, and separate the latch 504 on the push ring 503 from the slot 406 on the outer wall of the locking half-ring 401. At this time, the connection between the two locking half-rings 401 is released;

[0062] 2. Separate the locking half-rings 401: Remove the two locking half-rings 401 from the outer wall of the support cylinder 101 to complete the separation of the locking mechanism and the support cylinder 101;

[0063] 3. Remove the eccentric bearing 3: First, remove the blocking ring 701 with the aid of the stop lever 703, insert the guide block 706 into the guide groove 103, drive the guide block 706 to move in the guide groove 103, and use the reaction force to make the end of the support cylinder 101 contract inward. At this time, the eccentric bearing 3 can be easily removed from the support cylinder 101. Reverse the rotation of the blocking ring 701 to drive the guide block 706 to move reversely in the guide groove 103, and use the reaction force to make the end of the support cylinder 101 expand outward. At this time, it is convenient to remove the support cylinder 101 and the first compensation mechanism 2.
