Description

Technical Field

[0001] This utility model relates to the technical field of bearing vibration reduction equipment, specifically to a bearing vibration reduction device. Background Technology

[0002] Bearing assembly is a commonly used mechanical component. It mainly includes the movable ball bearing part and the bearing housing part that provides fixed support. The main function of the bearing housing is to fix the ball bearing to the bracket or machine base.

[0003] In related technologies, such as the bearings installed in the geared motors of textile equipment, the bearings need to be fixed to the equipment bracket by the bearing base, so as to support and fix the bearings and enable the motor to drive the bearings to rotate.

[0004] However, in current applications of bearing housings, bolts are typically used to connect and fix the bearing housing to the support plate on the equipment bracket. In actual applications, mechanical equipment will cause mechanical vibration during operation, and most bearing housings do not have a vibration damping effect. As a result, the bearing housing fixed to the equipment bracket will vibrate frequently, which will cause the bearing fixed to the bearing housing to wear. Over time, the service life of the bearing will be greatly reduced, leading to an increase in the frequency of bearing replacement. To solve the above problems, a bearing vibration damping device is proposed. Utility Model Content

[0005] In view of this, the present invention provides a bearing vibration damping device. The present invention absorbs and buffers the vibration energy outside the bearing housing through the vibration damping component, thereby reducing the vibration force transmitted to the bearing, reducing the vibration of the bearing housing, and thus reducing the vibration frequency of the bearing housing and the bearing, making the bearing fixed on the bearing housing run more stably, thereby preventing the bearing from wearing out too quickly.

[0006] To solve the above-mentioned technical problems, this utility model provides a bearing vibration damping device, including a seat body provided on the upper part of the bearing housing and a mounting plate provided on the lower part. The mounting plate has mounting holes at both ends. A vibration damping box is fixedly installed between the seat body and the mounting plate. A buffer component is symmetrically arranged in the middle of the vibration damping box. Multiple vibration damping components are provided on the left and right sides of each buffer component. Each vibration damping component includes a rubber vibration damping pad embedded and connected to the bottom of the seat body. A vibration damping spring is centrally located at the bottom of the rubber vibration damping pad. A vibration damping base is fixedly installed at the bottom of the vibration damping spring. A damping rod is fixedly installed along the axial direction of the inner ring of the vibration damping spring. The bottom of the vibration damping base is connected to the bottom of the vibration damping box.

[0007] The bottom of the shock-absorbing base is equipped with a buffer pad, which is used to connect the shock-absorbing components to the shock-absorbing box. The outer surface of the rubber shock-absorbing pad is equipped with multiple auxiliary components, which are used to assist in supporting the rubber shock-absorbing pad.

[0008] Each auxiliary component includes a telescopic sleeve that extends and retracts in sync with the telescopic spring. The upper end of each telescopic sleeve is connected to a coaxial rubber damping pad, and the lower end of each telescopic sleeve is connected to a coaxial buffer plate. A telescopic spring is fixedly installed inside each telescopic sleeve. The telescopic spring is used to elastically deform in sync with the damping spring. When the damping spring contracts, the telescopic spring contracts synchronously, which can disperse the pressure on the damping spring and thus prevent the damping spring from wearing out too quickly.

[0009] Each buffer assembly includes a pair of inclined buffer rods. The buffer rods are used to reduce the vibration force on the middle of the seat. Each pair of buffer rods is designed to cross to form an X shape. The cross design of the buffer rods can improve the support performance of the buffer rods. Each buffer rod has an upper connecting block on the top side of its top, which is used to connect the top of the inclined buffer rod to the seat. Each buffer rod has a lower connecting block on the bottom side of its bottom, which is used to connect the bottom of the inclined buffer rod to the shock-absorbing box, thereby supporting the buffer rod. Each upper connecting block is connected to the bottom of the seat, and each lower connecting block is connected to the bottom of the shock-absorbing box.

[0010] Each buffer rod has a first buffer post at its top lower side, which reduces the vibration force transmitted from the buffer rod to the shock absorber housing. Each buffer rod has a second buffer post at its bottom upper side, which reduces the vibration force transmitted from the buffer rod to the base. Each first buffer post is connected to the bottom of the shock absorber housing, and each second buffer post is connected to the bottom of the base. This allows the upper connecting block, in conjunction with the second buffer post, to reinforce and support the bearing installed in the middle of the base, and the lower connecting block, in conjunction with the first buffer post, to reinforce and support the bearing installed in the middle of the base.

[0011] Each pair of buffer bars has a rotating shaft in the middle, which connects the two buffer bars to form a whole, improving the support capacity of a single buffer bar and the overall shock absorption effect. Each rotating shaft has a positioning buckle at both ends to prevent the rotating shaft from falling off the buffer bar, and each positioning buckle is connected to the buffer bar next to it.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. By absorbing and buffering the vibration energy outside the bearing housing through the shock absorption components, the vibration force transmitted to the bearing is reduced, the vibration of the bearing housing is reduced, and the vibration frequency of the bearing housing and the bearing is reduced, making the bearing fixed on the bearing housing run more stably, thereby preventing the bearing from wearing out too quickly.

[0014] 2. The cross-design of the buffer rods improves their support performance. The upper connecting block connects the top of the inclined buffer rod to the base, and the lower connecting block connects the bottom of the inclined buffer rod to the shock-absorbing box, thus supporting the buffer rod. The first buffer column reduces the vibration force transmitted from the buffer rod to the shock-absorbing box, and the second buffer column reduces the vibration force transmitted from the buffer rod to the base. The upper connecting block, together with the second buffer column, reinforces the bearing installed in the middle of the base, and the lower connecting block, together with the first buffer column, reinforces the bearing installed in the middle of the base. This improves the connection between the bearing seat and the equipment bracket, making the bolts on the mounting holes less likely to fall off due to vibration.

[0015] 3. The rotating shaft is used to connect the two buffer bars, thereby forming a whole, improving the support capacity of a single buffer bar and the overall shock absorption effect. The positioning buckle is used to prevent the rotating shaft from falling off the buffer bar. Attached Figure Description

Figure 1-7 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0025] like Figure 1-7 As shown: This embodiment provides a bearing vibration damping device, including a seat body 101 disposed on the upper part of a bearing housing 100 and a mounting plate 102 disposed on the lower part. The seat body 101 has a bearing mounting port on its upper part for mounting the bearing. Mounting holes 103 are provided at both ends of the mounting plate 102 for mounting bolts, connecting and fixing the mounting plate 102 to a support plate on the equipment bracket, thereby connecting and fixing the bearing housing 100 to the equipment bracket. A vibration damping box 200 is fixedly disposed between the seat body 101 and the mounting plate 102. The vibration box 200 is used to enclose the buffer assembly 201 and the shock-absorbing assembly 300, preventing dust from entering the buffer assembly 201 and the shock-absorbing assembly 300 and affecting the service life of the components. A buffer assembly 201 is symmetrically arranged in the center of the shock-absorbing box 200. The buffer assembly 201 is used to support the middle of the base 101 and reduce the vibration force transmitted from the base to the base 101. Multiple shock-absorbing assemblies 300 are arranged on both sides of each buffer assembly 201, preferably four on each side. The 0 is used to absorb and buffer the vibration energy outside the bearing housing 100, thereby reducing the vibration force transmitted to the bearing, reducing the vibration of the bearing housing 100, making the bearing fixed on the bearing housing 100 run more stably, and thus reducing the coefficient of friction between the bearing housing 100 and the bearing, preventing the bearing from wearing out too quickly. Each damping component 300 includes a rubber damping pad 301 embedded and connected to the bottom of the housing 101. The rubber damping pad 301 is fixed to the bottom of the housing 101 by embedded connection or by bolt connection. A shock-absorbing spring 302 is centrally located. The shock-absorbing spring 302 and the rubber shock-absorbing pad 301 can be embeddedly connected. A shock-absorbing base 303 is fixedly installed at the bottom of the shock-absorbing spring 302. The shock-absorbing base 303 and the shock-absorbing spring 302 can be welded or fixed by bolts and clamps. A damping rod 304 is fixedly installed in the center of the inner ring of the shock-absorbing spring 302 along its axial direction. The damping rod 304 is used for damping control. The damping rod 304 can be a hydraulic piston rod. The bottom of the shock-absorbing base 303 is fixedly connected to the bottom of the shock-absorbing box 200 by bolts.

[0026] During use, the shock absorption component 300 absorbs and buffers the vibration energy outside the bearing housing 100, thereby reducing the vibration force transmitted to the bearing and reducing the vibration of the bearing housing 100. This makes the bearing fixed on the bearing housing 100 run more stably, thereby reducing the friction coefficient between the bearing housing 100 and the bearing and preventing the bearing from wearing out too quickly.

[0027] This embodiment provides a bearing vibration damping device.

[0028] like Figure 2 , 6 As shown in Figure 7: A buffer pad 305 is provided at the bottom of the shock-absorbing base 303. The buffer pad 305 is fixed to the shock-absorbing base 303 by bolts. The buffer pad 305 can be made of wood. The buffer pad 305 is used to connect the shock-absorbing component 300 to the shock-absorbing box 200. The buffer pad 305 is fixed to the bottom of the shock-absorbing box 200 by bolts. Multiple auxiliary components 400 are provided on the outer surface of the rubber shock-absorbing pad 301. The auxiliary components 400 are used to reduce the pressure on the shock-absorbing spring 302, thereby preventing the shock-absorbing spring 302 from being worn out too quickly. The auxiliary components 400 are used to assist in supporting the rubber shock-absorbing pad 301.

[0029] Its effects are as follows: the buffer pad 305 is used to connect the shock absorption assembly 300 to the shock absorption box 200, and the auxiliary assembly 400 is used to reduce the pressure on the shock absorption spring 302, thereby preventing the shock absorption spring 302 from being worn out too quickly.

[0030] like Figure 2 , 6 As shown in Figure 7: Each auxiliary component 400 includes a telescopic sleeve 401. Preferably, three auxiliary components 400 are arranged at 120° intervals. A connecting ring is provided on the top outer wall of the telescopic sleeve 401, which is fixed to the rubber shock-absorbing pad 301 by bolts. A positioning ring is provided on the bottom outer wall of the telescopic sleeve 401, which is fixed to the buffer pad 305 by bolts. The telescopic sleeve 401 is used to extend and retract following the telescopic spring 402. The upper end of each telescopic sleeve 401 is connected to its coaxial rubber shock-absorbing pad 301, and the lower end of each telescopic sleeve 401 is... A telescopic spring 402 is fixedly installed inside each telescopic sleeve 401, connected to a buffer pad 305 on the same axis. The top of the telescopic spring 402 is connected to the inner wall of the top of the telescopic sleeve 401 through a connecting block, and the bottom of the telescopic spring 402 is connected to the inner wall of the bottom of the telescopic sleeve 401 through a connecting block. The telescopic spring 402 is used to follow the shock absorber spring 302 in elastic deformation. When the shock absorber spring 302 contracts, the telescopic spring 402 contracts synchronously, which can disperse the pressure on the shock absorber spring 302 and thus prevent the shock absorber spring 302 from being worn out too quickly.

[0031] Its effect is as follows: the telescopic sleeve 401 is used to extend and retract with the telescopic spring 402, and the telescopic spring 402 is used to elastically deform with the shock absorber spring 302. When the shock absorber spring 302 contracts, the telescopic spring 402 contracts synchronously, which can disperse the pressure on the shock absorber spring 302, thereby preventing the shock absorber spring 302 from being worn out too quickly, thus improving the service life of the component.

[0032] like Figure 2 , 3 As shown in Figures 4 and 5: Each buffer assembly 201 includes a pair of inclined buffer rods 202. The buffer rods 202 are used to reduce the vibration force on the middle part of the seat 101. Each pair of buffer rods 202 is designed to cross to form an X shape. The cross design of the buffer rods 202 can improve the support performance of the buffer rods 202. Each buffer rod 202 has an upper connecting block 203 on the upper side of its top end. The upper connecting block 203 and the buffer rod 202 can be fixed by bolts. The upper connecting block 203 is connected to the bottom of the seat 101. The upper connecting block 203 is used to connect the top of the inclined buffer rod 202 to the base 101 via bolts. A lower connecting block 204 is provided on the lower side of the bottom end of each buffer rod 202. The lower connecting block 204 is fixed to the buffer rod 202 via bolts, and also to the shock absorber housing 200 via bolts. The lower connecting block 204 connects the bottom of the inclined buffer rod 202 to the shock absorber housing 200, thereby supporting the buffer rod 202. Each upper connecting block 203... All are connected to the bottom of the base 101, and each lower connecting block 204 is connected to the bottom of the shock absorber 200. A first buffer post 205 is provided on the lower side of the top of each buffer rod 202. The first buffer post 205 is used to reduce the vibration force transmitted from the buffer rod 202 to the shock absorber 200. A second buffer post 206 is provided on the upper side of the bottom of each buffer rod 202. The first buffer post 205 and the second buffer post 206 have the same structure. Both the first buffer post 205 and the second buffer post 206 can be... Made of rubber, the second buffer post 206 is used to reduce the vibration force transmitted from the buffer rod 202 to the seat 101. Each first buffer post 205 is fixed to the bottom of the shock absorber 200 by bolts, and each second buffer post 206 is fixed to the bottom of the seat 101 by bolts. Thus, the upper connecting block 203, together with the second buffer post 206, reinforces and supports the bearing installed in the middle of the seat 101, and the lower connecting block 204, together with the first buffer post 205, reinforces and supports the bearing installed in the middle of the seat 101.

[0033] The effect is as follows: the cross design of the buffer rod 202 can improve the support performance of the buffer rod 202; the upper connecting block 203 is used to connect the top of the inclined buffer rod 202 to the seat 101; the lower connecting block 204 is used to connect the bottom of the inclined buffer rod 202 to the shock absorber box 200, thereby supporting the buffer rod 202; the first buffer column 205 is used to reduce the vibration force transmitted from the buffer rod 202 to the shock absorber box 200; the second buffer column 206 is used to reduce the vibration force transmitted from the buffer rod 202 to the seat 101; thus, the upper connecting block 203, together with the second buffer column 206, reinforces and supports the bearing installed in the middle of the seat 101; and the lower connecting block 204, together with the first buffer column 205, reinforces and supports the bearing installed in the middle of the seat 101.

[0034] like Figure 2 , 3 As shown in Figures 4 and 5: Each pair of buffer rods 202 has a rotating shaft 207 rotatably mounted in the middle. Each buffer rod 202 has an opening in the middle, and the rotating shaft 207 is rotatably mounted in the opening. The rotating shaft 207 is used to connect the two buffer rods 202, thereby making the two buffer rods 202 form a whole, improving the support capacity of a single buffer rod 202 and the overall shock absorption effect. Each rotating shaft 207 has a positioning buckle 208 at both ends. The positioning buckle 208 is used to support the rotating shaft 207 and prevent the rotating shaft 207 from falling off the buffer rod 202. Each positioning buckle 208 is fixed to the buffer rod 202 adjacent to it by bolts.

[0035] Its effect is as follows: the rotating shaft 207 is used to connect the two buffer rods 202, thereby making the two buffer rods 202 form a whole, improving the support capacity of the single buffer rod 202 and the overall shock absorption effect; the positioning buckle 208 is used to prevent the rotating shaft 207 from falling off the buffer rod 202.

[0036] Working principle: The shock absorption component 300 absorbs and buffers the vibration energy outside the bearing housing 100, thereby reducing the vibration force transmitted to the bearing and reducing the vibration of the bearing housing 100. This makes the bearing fixed on the bearing housing 100 run more stably, thereby reducing the friction coefficient between the bearing housing 100 and the bearing and preventing the bearing from wearing out too quickly. The buffer component 201 further improves the effect of the shock absorption component 300, so that the housing 101 is supported while also reducing the vibration energy transmitted to the housing 101 by the equipment bracket, thereby reducing the vibration frequency of the bearing housing 100. This can further reduce the vibration frequency between the bearing housing 100 and the bearing, thereby increasing the service life of the bearing.

[0037] Furthermore, it should be noted that, in the description of this utility model, 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 according to the specific circumstances.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
