Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical power transmission devices, specifically relating to a floating support bearing transmission seat. Background Technology

[0002] In the study of mechanical power transmission, the bearing drive housing is an indispensable component, serving as a support for mounting bearings. However, in existing test benches, the bearing drive housing is a one-piece round hole type, requiring extremely high assembly precision when installing bearings and rotating shafts. This makes installation, disassembly, and maintenance difficult and inefficient. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a floating support bearing transmission seat to solve the technical problems of the current bearing transmission seat requiring extremely high assembly precision and being difficult to disassemble and assemble when installing bearings and rotating shafts.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a floating support bearing transmission seat, which includes a body, a mounting hole provided on the body, and a clamping assembly detachably connected to the mounting hole; the clamping assembly includes two thrust clamping arc blocks and one fixed clamping arc block, the fixed clamping arc block is detachably connected to the middle position of the bottom of the mounting hole, the two thrust clamping arc blocks are distributed on both sides of the fixed clamping arc block and are detachably connected to the fixed clamping arc block; a disassembly hole is provided through the thrust clamping arc block to align with the fixed clamping arc block, and an internal thread is provided in the disassembly hole; the thrust clamping arc block cooperates with the top of the mounting hole to clamp the bearing.

[0005] Preferably, the thrust clamping arc block is provided with a first connecting hole parallel to the disassembly hole, and the fixed clamping arc block is provided with a first threaded hole aligned with the first connecting hole. The first connecting bolt passes through the first connecting hole and is threadedly engaged with the first threaded hole, thereby realizing the detachable connection between the thrust clamping arc block and the fixed clamping arc block.

[0006] Preferably, the connecting hole is a stepped hole.

[0007] Preferably, the side wall of the fixed clamping arc block close to the inner wall of the mounting hole is provided with a second threaded hole, and the second connecting bolt passes through the second connecting hole provided on the body and is threadedly engaged with the second threaded hole to realize the detachable connection between the fixed clamping arc block and the mounting hole.

[0008] Preferably, the bottom of the fixed clamping arc block is provided with an adjustment hole, and the bottom of the body is provided with a third threaded hole that communicates with the mounting hole. The third bolt is threaded and passes through the third threaded hole before extending into the adjustment hole to adjust the height of the fixed clamping arc block.

[0009] Preferably, fixed flanges are provided at both ends of the body outside the mounting holes.

[0010] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0011] This utility model provides a clamping component in the mounting hole of the transmission seat body. The clamping component is located at the bottom of the mounting hole and clamps the bearing from bottom to top with the mounting hole. A connecting rotating shaft is sleeved inside the bearing. The bearing and rotating shaft are fixed by the separate combination of the clamping component and the mounting hole. This reduces the requirements for the dimensional accuracy of the bearing and the mounting hole, and the separate design facilitates installation, disassembly and maintenance, thus improving the efficiency of use. The clamping assembly includes a fixed clamping arc block and two thrust clamping arc blocks. The fixed clamping arc block is detachably connected to the bottom center of the mounting hole, and the two thrust clamping arc blocks are detachably connected to both sides of the fixed clamping arc block. The two thrust clamping arc blocks clamp the bearing from bottom to top with the mounting hole, achieving fixed installation of the bearing. The detachable design reduces the requirements for fitting precision and facilitates disassembly and assembly. By providing a disassembly hole through the thrust clamping arc block, aligned with the fixed clamping arc block, and with an internal thread inside the disassembly hole, a bolt is used to connect to the disassembly hole when disassembly is required. After the bolt passes through the disassembly hole, it continues to be screwed on. At this time, the bolt is pressed against the fixed clamping arc block, and due to the thrust of the bolt continuing to advance, the thrust clamping arc block is pushed back out of the mounting hole, realizing the disassembly of the bearing and rotating shaft, greatly improving the disassembly and assembly efficiency.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments, and do not limit the scope of the present utility model.

[0018] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The specific implementation method is as follows:

[0021] like Figure 1-4 As shown, a floating support bearing transmission seat includes a body 1 and a clamping assembly. A mounting hole 2 is provided through the body 1, and the upper part of the mounting hole 2 is arc-shaped and matches the bearing 6. The clamping assembly is detachably connected to the mounting hole 2 and is used to clamp the bearing 6 in conjunction with the mounting hole 2. A rotating shaft 7 is connected to the bearing 6. Rotational transmission is achieved through the support of the body 1.

[0022] The clamping assembly includes a fixed clamping arc block 3 and two thrust clamping arc blocks 4. The upper ends of both the fixed clamping arc block 3 and the thrust clamping arc blocks 4 are arc-shaped, matching the bearing 6. The fixed clamping arc block 3 is detachably connected to the bottom center of the mounting hole 2. The two thrust clamping arc blocks 4 are located on the left and right sides of the fixed clamping arc block 3, coaxially arranged with it, and detachably connected to the fixed clamping arc block 3. Based on this, the thrust clamping arc blocks 4 engage with the top of the mounting hole 2 from bottom to top, clamping and fixing the bearing 6, thus achieving the fixed installation of the bearing 6.

[0023] A disassembly hole 42 is provided through the left and right sides of the thrust clamping arc block 4, and an internal thread is provided in the disassembly hole 42. The position on the fixed clamping arc block 3 that aligns with the disassembly hole 42 is a plane, without any holes. Based on this, when it is necessary to disassemble the bearing 6 and the rotating shaft 7, the connection between the thrust clamping arc block 4 and the fixed clamping arc block 3 is disassembled. A long bolt is connected in the disassembly hole 42. The long bolt passes through the disassembly hole and abuts against the fixed clamping arc block 3. By continuing to tighten the long bolt, since the fixed clamping arc block 3 is connected to the body 1, the counter-thrust generated by the continued tightening will push the thrust clamping arc block 4 out of the mounting hole 2, thus realizing the disassembly of the bearing 6 from the body 1. Disassembly is convenient and maintenance is easy.

[0024] Furthermore, a first connecting hole 41 parallel to the disassembly hole 42 is provided on the thrust clamping arc block 4, and a first threaded hole 31 is provided on the fixed clamping arc block 3 at a position aligned with the first connecting hole 41. A first connecting bolt passes through the first connecting hole 41 and is threadedly connected to the first threaded hole 31, thereby realizing a detachable connection between the thrust clamping arc block 4 and the fixed clamping arc block 3. In this embodiment, multiple pairs of first connecting holes 41 and first threaded holes 31 are provided to ensure the reliability of the connection between the thrust clamping arc block 4 and the fixed clamping arc block 3.

[0025] Furthermore, the first connecting hole 41 is a stepped hole to ensure that the end of the first connecting bolt is submerged in the stepped hole when connected, so that there are no protruding points on the side of the thrust clamping arc block 4.

[0026] Furthermore, the front and rear sides of the fixed clamping arc block 3 that are in close contact with the inner wall of the mounting hole 2 are provided with second threaded holes 32. A second connecting hole communicating with the inner wall of the mounting hole 2 is provided on the front and rear side walls of the main body 1. The second connecting bolt passes through the second connecting hole and is threadedly connected to the second threaded hole 32, thus realizing a detachable connection between the fixed clamping arc block 3 and the mounting hole 2.

[0027] Furthermore, vertical adjustment holes 33 are provided at the four parts of the fixed clamping arc block 3. The adjustment holes 33 are smooth holes. A third threaded hole communicating with the mounting hole 2 is provided at the bottom of the body 1. The third bolt passes through the third threaded hole through the threaded engagement. After passing through the third threaded hole, the third bolt extends into and presses against the top of the adjustment hole 33. Based on this, by turning the third bolt, its height is adjusted. The third bolt pushes upward and adjusts the height of the fixed clamping arc block 3, thereby adjusting the transmission clearance of the rotating shaft, improving the transmission quality and extending the service life. In this embodiment, in order to accommodate the adjustment of the height of the fixed clamping arc block 3, the second connecting hole on the body 1 is an elongated hole.

[0028] Furthermore, to further enhance the reliability of the connection between the body 1 and the bearing 6, fixing flanges 5 are provided at both ends of the body 1 outside the mounting holes 2. The fixing flanges 5 are detachably connected to the body 1 by bolts. More specifically, bolt holes for connecting the fixing flanges 5 are also provided on the outer wall of the thrust clamping arc block 4. The lower part of the fixing flanges 5 is bolted to the thrust clamping arc block 4.

[0029] In this embodiment, when the floating support bearing transmission seat is in use, the fixed clamping arc block 3 is connected to the middle position of the bottom of the mounting hole 2 by the second connecting bolt, and the height of the fixed clamping arc block 3 can be adjusted as needed. The thrust clamping arc block 4 is connected to the fixed clamping arc block 3 by the first connecting bolt, and the arc shape at the upper end of the thrust clamping arc block 3 clamps the bearing 6 at the upper end of the mounting hole 2, thereby fixing the two bearings 6 in the mounting hole 2. The rotating shaft 7 is connected to the two bearings 6, realizing the connection between the rotating shaft 7, the bearings 6 and the transmission seat body 1. Based on this, the fixing of the bearings 6 is achieved by the separate clamping components and the mounting hole 2. Compared with the transmission seat with an integrated circular hole in the prior art, the separate setting can adjust the transmission clearance of the rotating shaft, reduce the requirement for fitting accuracy, improve the transmission quality and extend the service life. In addition, the separate and detachable setting means that when the clearance becomes too large due to component wear during use, only the thrust clamping arc block 4 needs to be removed for repair to restore the original performance. It can be repaired and reused multiple times, reducing the cost of use. The removal hole 42 on the thrust clamping arc block 4 facilitates the push-clamping arc block 4 to be pushed out of the mounting hole 2 by the counter-thrust force generated by the bolt tightening, so as to smoothly remove the rotating shaft 7, which facilitates disassembly and maintenance and improves work efficiency.

[0030] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
