Description

Technical Field

[0001] The utility model relates to the technical field of bearing seats, in particular to a shock-absorbing bearing seat. Background Art

[0002] The bearing seat, also known as the bearing box, is the key external support structure for the shaft and bearing in the machine equipment. It is responsible for supporting and fixing the bearing, ensuring the stable operation of the bearing and bearing various loads. The bearing seat is compact in design, flexible in rotation, easy to install and maintain, to meet the application of different machines and equipment. According to the shape and structure, the bearing seat includes various types such as spherical seat, vertical seat, square seat, etc.

[0003] At present, bolts are usually used to connect and fix the bearing seat and the base plate in the use of bearing seats. However, in actual applications, the bearing seat does not have a certain degree of shock-absorbing effect, which causes the bearing seat to be damaged due to frequent vibrations and affects the connection relationship between the bearing seat and the base plate. For this reason, we propose a shock-absorbing bearing seat to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a shock-absorbing bearing seat to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A shock-absorbing bearing seat comprises a bearing seat body, a bottom plate and a shock-absorbing device, wherein the bearing seat body and the bottom plate are respectively connected to the shock-absorbing device, and the shock-absorbing device comprises a cylinder body and a top plate, a moving block is fixedly connected to the top plate, the moving block is slidably connected to the cylinder body, a pressure plate is fixedly connected to the side of the moving block away from the top plate, a fixing plate is symmetrically arranged and fixedly connected to the outer side of the cylinder body, a partition is fixedly connected to the cylinder body, the partition separates the cylinder body into a first chamber and a second chamber, the top plate is connected to the bearing seat body by bolts, the fixing plate is connected to the bottom plate by bolts, a shock-absorbing component for providing a shock-absorbing effect is connected to the cylinder body, and a damping component for providing a damping effect is connected to the inside of the first chamber.

[0007] When the bearing seat body vibrates, the bearing seat body will transmit the vibration to the top plate. At this time, the moving block fixedly connected to the top plate will move back and forth in the vertical direction. At this time, the shock-absorbing components and damping components provided can be used together to absorb the vibration and impact brought by the moving plate, thereby achieving a buffering effect, thereby reducing the amplitude of the vibration of the bearing seat body and stabilizing the bearing seat body, thereby reducing the stress on the bearing and the bearing seat, and avoiding damage or failure due to excessive vibration.

[0008] A further improvement of the technical solution of the utility model is that the shock absorbing component includes a spring, one end of the spring is fixedly connected to the pressure plate, the other end of the spring is fixedly connected to the partition, a plurality of through holes are provided on the pressure plate, a plurality of support frames are symmetrically arranged inside the first chamber, the support frames are fixedly connected to the cylinder body, a pressure roller is rotatably connected to the support frames, an extrusion layer is provided on the outer surface of the pressure roller, a pressing sheet is fixedly connected to the moving block, and the pressure roller and the pressing sheet are used in conjunction with each other.

[0009] The above-mentioned technical solution is adopted. In this solution, when the bearing seat body is vibrated, the moving block will drive the pressure plate to move back and forth in the vertical direction under the action of the elastic force of the spring. At this time, air flows from the through hole. At the same time, when the moving block moves, the pressure roller keeps squeezing the pressure plate. The movement of the moving block will drive the pressure roller to rotate through the pressure plate, which will increase the friction between the pressure roller and the moving block, thereby slowing down the moving speed of the moving block and the amplitude of the vibration of the bearing seat body.

[0010] A further improvement of the technical solution of the utility model is that the damping component comprises a damping block, the damping blocks are symmetrically arranged, a curved surface is arranged on the damping block, and the damping block is used in conjunction with the pressure roller.

[0011] The above-mentioned technical solution is adopted, in which a damping block is provided to contact the pressure roller so that the force required for the pressure roller to rotate becomes larger. In this way, the movement speed of the moving block can be further slowed down by providing the damping block. At the same time, by providing a curved surface on the damping block, the contact area with the pressure roller can be increased, thereby increasing the friction between the pressure roller and the damping block and slowing down the vibration amplitude of the bearing seat body.

[0012] A further improvement of the technical solution of the utility model is that the shape of the support frame is a triangle.

[0013] The above technical solution is adopted. In this solution, because the moving block will also apply an opposite force to the support frame through the pressure roller when it moves, the shape of the support frame is set to be a triangle because the triangle has the advantage of good stability, thereby improving the stability and bearing capacity of the structure.

[0014] A further improvement of the technical solution of the utility model is that the materials of the extrusion layer and the pressing sheet are both rubber.

[0015] The above technical solution is adopted, in which the material of the extrusion layer and the pressing sheet is set to be rubber because rubber has good friction properties and can provide stable friction force, and rubber can effectively absorb impact force.

[0016] A further improvement of the technical solution of the utility model is that the bolt member is a semi-threaded bolt, the semi-threaded bolt is slidably connected to the fixing plate, the semi-threaded bolt is threadedly connected to the bottom plate, and a buffer pad is arranged between the fixing plate and the bottom plate.

[0017] By adopting the above technical solution, in which the bolt member is set to be a semi-threaded bolt and a buffer pad for use in combination, the buffer pad can be used to absorb the pressure generated by the vibration of the bearing seat body, thereby reducing the influence of the vibration of the bearing seat body on the connection relationship between the semi-threaded bolt and the base plate.

[0018] A further improvement of the technical solution of the utility model is that the material of the buffer pad is silica gel.

[0019] The above technical solution is adopted, in which the material of the buffer pad is set to be silicone because silicone has good comprehensive durability and can maintain its mechanical strength and elasticity for a long time.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0021] 1. The utility model provides a shock-absorbing bearing seat. When the bearing seat body vibrates, the bearing seat body will transmit the vibration to the top plate. At this time, the moving block fixedly connected to the top plate will move back and forth in the vertical direction. At this time, the shock-absorbing component and the damping component are used together to absorb the vibration and impact brought by the moving plate, thereby achieving a buffering effect, thereby reducing the amplitude of the vibration of the bearing seat body, making the bearing seat body tend to be stable, thereby reducing the stress on the bearing and the bearing seat, and avoiding damage or failure due to excessive vibration.

[0022] 2. The utility model provides a shock-absorbing bearing seat, which is provided with a damping block in contact with the pressure roller so that the force required for the pressure roller to rotate becomes larger. In this way, the movement speed of the moving block can be further slowed down by providing the damping block. At the same time, by providing a curved surface on the damping block, the contact area with the pressure roller can be increased, thereby increasing the friction between the pressure roller and the damping block and slowing down the vibration amplitude of the bearing seat body.

[0023] 3. The utility model provides a shock-absorbing bearing seat. When the moving block moves, it will also give an opposite force to the support frame through the pressure roller. The shape of the support frame is set to be a triangle because the triangle has the advantage of good stability, thereby improving the stability and bearing capacity of the structure.

DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the embodiments:

[0034] Example

[0035] like Figure 1 , Figure 2 As shown, the utility model provides a shock-absorbing bearing seat, including a bearing seat body 1, a bottom plate 2 and a shock-absorbing device, the bearing seat body 1 and the bottom plate 2 are respectively connected to the shock-absorbing device, the shock-absorbing device includes a cylinder body 3 and a top plate 4, a moving block 5 is fixedly connected to the top plate 4, the moving block 5 is slidably connected to the cylinder body 3, a pressure plate 6 is fixedly connected to the side of the moving block 5 away from the top plate 4, a fixing plate 7 is symmetrically arranged and fixedly connected to the outer side of the cylinder body 3, a partition plate 8 is fixedly connected inside the cylinder body 3, the partition plate 8 divides the cylinder body 3 into a first chamber 9 and a second chamber 10, the top plate 4 is connected to the bearing seat body 1 by bolts, the fixing plate 7 is connected to the bottom plate 2 by bolts, a shock-absorbing component for providing a shock-absorbing effect is connected inside the cylinder body 3, and a damping component for providing a damping effect is connected inside the first chamber 9.

[0036] In this embodiment, when the bearing seat body 1 vibrates, the bearing seat body 1 will transmit the vibration to the top plate 4. At this time, the moving block 5 fixedly connected to the top plate 4 will move back and forth in the vertical direction. At this time, the shock-absorbing components and damping components provided can be used together to absorb the vibration and impact brought by the moving plate, thereby achieving a buffering effect, thereby reducing the amplitude of the vibration of the bearing seat body 1, making the bearing seat body 1 tend to be stable, thereby reducing the stress on the bearing and the bearing seat, and avoiding damage or failure due to excessive vibration.

[0037] like Figure 3 , Figure 5 As shown, in the present embodiment, preferably, the shock absorbing component includes a spring 11, one end of the spring 11 is fixedly connected to the pressure plate 6, the other end of the spring 11 is fixedly connected to the partition 8, a plurality of through holes 12 are provided on the pressure plate 6, a plurality of support frames 13 are symmetrically arranged inside the first chamber 9, the support frames 13 are fixedly connected to the cylinder body 3, a pressure roller 14 is rotatably connected to the support frame 13, an extrusion layer 15 is provided on the outer surface of the pressure roller 14, a pressing sheet 16 is fixedly connected to the moving block 5, and the pressure roller 14 and the pressing sheet 16 are used in conjunction with each other.

[0038] When the bearing seat body 1 is vibrated, the moving block 5 will drive the pressure plate 6 to move back and forth in the vertical direction under the action of the elastic force of the spring 11. At this time, air flows from the through hole 12. At the same time, when the moving block 5 moves, the pressure roller 14 keeps squeezing the pressure sheet 16. The movement of the moving block 5 will drive the pressure roller 14 to rotate through the pressure sheet 16, which will increase the friction between the pressure roller 14 and the moving block 5, thereby slowing down the moving speed of the moving block 5 and the amplitude of the vibration of the bearing seat body 1.

[0039] like Figure 6 As shown, preferably, the damping component includes a damping block 17 , which is symmetrically arranged, and a curved surface 18 is arranged on the damping block 17 , and the damping block 17 is used in conjunction with the pressure roller 14 .

[0040] By providing a damping block 17 in contact with the pressure roller 14, the force required for the pressure roller 14 to rotate becomes larger, so that the movement speed of the moving block 5 can be further slowed down by providing the damping block 17. At the same time, by providing a curved surface 18 on the damping block 17, the contact area with the pressure roller 14 can be increased, thereby increasing the friction between the pressure roller 14 and the damping block 17 and slowing down the vibration amplitude of the bearing seat body 1.

[0041] like Figure 1-5 As shown, preferably, the support frame 13 is in the shape of a triangle.

[0042] Because the moving block 5 will also exert an opposite force on the support frame 13 through the pressure roller 14 when moving, the shape of the support frame 13 is set to be a triangle because the triangle has the advantage of good stability, thereby improving the stability and bearing capacity of the structure.

[0043] like Figure 6 As shown, preferably, the materials of the extrusion layer 15 and the pressing sheet 16 are both rubber.

[0044] The material of the extrusion layer 15 and the pressing sheet 16 is rubber because rubber has good friction properties and can provide stable friction force, and rubber can effectively absorb impact force.

[0045] like Figure 7As shown, preferably, the bolt member is a semi-threaded bolt 19 , the semi-threaded bolt 19 is slidingly connected to the fixing plate 7 , the semi-threaded bolt 19 is threadedly connected to the base plate 2 , and a buffer pad 20 is provided between the fixing plate 7 and the base plate 2 .

[0046] By setting the bolt member to be a semi-threaded bolt 19 and a buffer pad 20 for use in combination, the buffer pad 20 can be used to absorb the pressure generated when the bearing seat body 1 vibrates, thereby reducing the impact of the vibration of the bearing seat body 1 on the connection relationship between the semi-threaded bolt 19 and the base plate 2.

[0047] like Figure 1 As shown, preferably, the material of the buffer pad 20 is silicone.

[0048] The material of the buffer pad 20 is silicone because silicone has good comprehensive durability and can maintain its mechanical strength and elasticity for a long time.

[0049] The following is a detailed description of the working principle of this type of shock-absorbing bearing seat.

[0050] like Figure 1-7As shown, when the bearing seat body 1 vibrates, the bearing seat body 1 will transmit the vibration to the top plate 4, and the moving block 5 fixedly connected to the top plate 4 will move back and forth in the vertical direction. At this time, the vibration and impact brought by the moving plate can be absorbed by the provided shock-absorbing components and damping components, which can play a buffering effect, thereby reducing the amplitude of the vibration of the bearing seat body 1, making the bearing seat body 1 tend to be stable, thereby reducing the stress on the bearing and the bearing seat, and avoiding damage or failure due to excessive vibration. When the bearing seat body 1 is vibrated, the moving block 5 will drive the pressure plate 6 to move back and forth in the vertical direction under the elastic force of the spring 11. At this time, air flows from the through hole 12. At the same time, when the moving block 5 moves, the pressure roller 14 keeps squeezing the pressing sheet 16. The movement of the moving block 5 will drive the pressure roller 14 to rotate through the pressing sheet 16, which will increase the friction between the pressing roller 14 and the moving block 5, thereby slowing down the moving speed of the moving block 5 and the amplitude of the vibration of the bearing seat body 1. By providing a damping block 17 in contact with the pressure roller 14, the force required for the pressure roller 14 to rotate becomes larger. In this way, the movement speed of the moving block 5 can be further slowed down by providing the damping block 17. At the same time, by providing a curved surface 18 on the damping block 17, the contact area with the pressure roller 14 can be increased, thereby increasing the friction between the pressure roller 14 and the damping block 17 and slowing down the vibration amplitude of the bearing seat body 1. Because the moving block 5 will also give the support frame 13 an opposite force through the pressure roller 14 when moving, the shape of the support frame 13 is set to be a triangle because the triangle has the advantage of good stability, thereby improving the stability and bearing capacity of the structure. The material of the extrusion layer 15 and the pressing sheet 16 is set to rubber because rubber has good friction properties and can provide stable friction. At the same time, rubber can effectively absorb impact force. By setting the bolt member to be a semi-threaded bolt 19 and a buffer pad 20 for use in combination, the buffer pad 20 can be used to absorb the pressure generated when the bearing seat body 1 vibrates, reducing the influence of the vibration of the bearing seat body 1 on the connection relationship between the semi-threaded bolt 19 and the base plate 2. The material of the buffer pad 20 is silicone because silicone has good comprehensive durability and can maintain its mechanical strength and elasticity for a long time.

[0051] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
