Description

Technical Field

[0001] This utility model relates to the field of bearing housings, and in particular to a shock-absorbing bearing housing. Background Technology

[0002] As users' requirements for equipment performance continue to increase, vibration damping bearing housings, as an important component for improving equipment performance, are becoming increasingly popular. Vibration damping bearing housings are a special bearing housing design that combines the basic functions of a bearing housing with a vibration damping mechanism. They are used to support and reduce vibration and noise during the operation of mechanical equipment, thereby improving the stability and service life of the equipment.

[0003] In existing technologies, vibration damping bearing housings mainly achieve vibration damping by placing damping springs between the bearing housing and the base, thereby absorbing vibration force through buffering. However, existing vibration damping bearing housings have certain limitations in use. Due to their relatively fixed design, it is difficult to adjust their installation height. In practical applications, different equipment and different working conditions have different requirements for the installation height of the bearing housing, which cannot meet the usage needs. Moreover, after long-term use, the damping springs are prone to aging and other failures, leading to a decrease in the vibration damping performance of the vibration damping bearing housing and affecting the normal operation of the equipment. Therefore, a vibration damping bearing housing is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the relatively fixed design of shock-absorbing bearing seats, the difficulty in adjusting their installation height, the different requirements for the installation height of bearing seats in practical applications, the inability to meet their usage needs, and the tendency of shock-absorbing springs to age and fail after long-term use, leading to a decline in the shock-absorbing performance of the shock-absorbing bearing seat and affecting the normal operation of the equipment. Therefore, this invention proposes a shock-absorbing bearing seat to solve the above problems.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A vibration damping bearing housing, comprising:

[0007] A mounting base and a shock absorber base, wherein the shock absorber base is disposed on the outer wall of the mounting base, and a base is disposed at the bottom of the shock absorber base, and a movable component is disposed on the base, the movable component comprising:

[0008] The adjustment unit includes a bidirectional screw and a push rod. One end of the bidirectional screw is rotatably connected to the inner cavity of the base via a bearing. A moving block is threadedly connected to the outer wall of the bidirectional screw. One end of the push rod is rotatably connected to the moving block via a pin. The other end of the push rod is rotatably connected to the outer wall of the shock absorber via a pin.

[0009] A limiting unit is disposed on the outer wall of the base, and the limiting unit is used to position the mounting base.

[0010] Preferably, the outer wall of the base has a circular hole, and an adjusting rod is movably inserted into the inner wall of the circular hole. The adjusting rod is fixedly connected to the outer wall of the bidirectional screw.

[0011] Preferably, the limiting unit includes a positioning plate and a positioning screw. The positioning plate is fixedly mounted on the outer wall of the adjusting rod. The outer wall of the positioning plate has positioning holes, and multiple sets of positioning holes are provided. The outer wall of the base is fixedly mounted with a fixing block. The outer wall of the fixing block has a threaded groove, and the positioning screw is threadedly connected in the threaded groove. The positioning screw is mated and inserted into the corresponding positioning hole.

[0012] Preferably, a transmission sprocket is fixedly provided on the outer wall of the bidirectional screw, and the two sets of transmission sprockets are connected by a transmission chain.

[0013] Preferably, the inner cavity of the shock absorber is provided with a damper, and one end of the damper is fixedly connected to a round rod. A sliding block is movably sleeved on the outer wall of the round rod, and the sliding block is fixedly set at the bottom of the mounting base. A shock absorber spring is movably sleeved on the outer wall of the round rod.

[0014] Preferably, the outer wall of the shock absorber seat has a connection port, and the inner wall of the connection port is rotatably connected to a baffle via a rotating shaft.

[0015] Preferably, the base has a movable opening at the top, and the bottom of the shock absorber is movably engaged within the movable opening.

[0016] Preferably, a rubber pad is fixedly adhered to the bottom of the base.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by setting the connection relationship between the mounting base, the shock absorber base, the base, the bidirectional screw, and the push rod, the user can rotate the adjusting rod to drive two sets of moving blocks to push two sets of push rods to move. The push rods push the shock absorber base upward, which in turn drives the mounting base upward, allowing the height of the mounting base to be adjusted to meet the installation requirements of different axis heights. This allows for reasonable adjustment of the gap between the bearing and the mechanical parts, thereby improving the adaptability and flexibility of the equipment. Furthermore, by setting the connection relationship between the shock absorber spring, the connecting port, the baffle, and the moving port, by continuing to rotate the adjusting rod, the shock absorber base drives the baffle upward, causing the baffle to move out of the base. At this point, the inner wall of the moving port can no longer restrict the baffle. By rotating the baffle downward, the connecting port opens, allowing the user to easily access and replace the shock absorber spring, thus extending the service life of the shock absorber bearing housing and ensuring that the shock absorber bearing housing always maintains a good working condition.

[0019] 2. In this utility model, by setting the connection relationship between the positioning plate, positioning holes, fixing block and positioning screw, multiple sets of positioning holes are set, corresponding to different limited positions. When the mounting base moves to the corresponding height position, the rotation of the adjusting rod is stopped, and the corresponding positioning hole is aligned with the thread groove on the fixing block. By rotating the positioning screw, the positioning screw moves along the thread groove towards the positioning plate, so that the positioning screw is inserted into and locked in the positioning hole, thereby fixing the position of the positioning plate, thereby fixing the position of the bidirectional screw, and thus stabilizing the mounting base at the height position for convenient use.

Detailed Implementation

[0027] 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, and not all embodiments.

[0028] Example: This example provides a shock-absorbing bearing housing, see [link / reference]. Figure 1-4 Specifically, including:

[0029] Mounting base 1 and shock absorber base 2, the shock absorber base 2 is disposed on the outer wall of mounting base 1, and a base 3 is disposed at the bottom of the shock absorber base 2, and a movable component is disposed on the base 3, the movable component including:

[0030] The adjustment unit includes a bidirectional screw 4 and a push rod 402. One end of the bidirectional screw 4 is rotatably connected to the inner cavity of the base 3 via a bearing. A moving block 401 is threadedly connected to the outer wall of the bidirectional screw 4. One end of the push rod 402 is rotatably connected to the moving block 401 via a pin. Two sets of moving blocks 401 are provided and symmetrically distributed on both sides of the bidirectional screw 4. The other end of the push rod 402 is rotatably connected to the outer wall of the shock absorber 2 via a pin. In use, the bidirectional screw 4 is rotated clockwise, causing the two sets of moving blocks 401 to move closer to each other. The moving blocks 401 push the push rod 402, causing the push rod 402 to rotate and push the shock absorber 2 upward. The upward movement of the shock absorber 2 causes the mounting base 1 to move upward, which facilitates the adjustment of the installation position of the mounting base 1 to adapt to the installation requirements of different axis heights. This allows for reasonable adjustment of the gap between the bearing and the mechanical parts, thereby improving the adaptability and flexibility of the equipment.

[0031] The limiting unit is disposed on the outer wall of the base 3, and the limiting unit is used to position the mounting base 1.

[0032] The outer wall of the base 3 has a round hole, and an adjusting rod 403 is movably inserted into the inner wall of the round hole. The adjusting rod 403 is fixedly connected to the outer wall of the bidirectional screw 4 and is used to extend the action point of the bidirectional screw 4 to facilitate user adjustment.

[0033] The limiting unit includes a positioning plate 405 and a positioning screw 408. The positioning plate 405 is fixedly mounted on the outer wall of the adjusting rod 403. The outer wall of the positioning plate 405 has positioning holes 406, and multiple sets of positioning holes 406 are provided, corresponding to different limiting positions. A fixing block 407 is fixedly mounted on the outer wall of the base 3. The outer wall of the fixing block 407 has a threaded groove, and the positioning screw 408 is threaded into the threaded groove. The positioning screw 408 is mated and inserted into the corresponding positioning hole 406. In use, when the mounting base 1 moves to the corresponding height position, the rotation of the adjusting rod 403 is stopped. At this time, the corresponding positioning hole 406 is aligned with the threaded groove on the fixing block 407. By rotating the positioning screw 408, the positioning screw 408 moves along the threaded groove towards the positioning plate 405, so that the positioning screw 408 is inserted into and locked into the positioning hole 406, thereby fixing the position of the positioning plate 405, thereby fixing the position of the bidirectional screw 4, and thus stabilizing the mounting base 1 at the height position for convenient use.

[0034] A transmission sprocket is fixedly installed on the outer wall of the bidirectional screw 4, and the two sets of transmission sprockets are connected by a transmission chain 404. There are two sets of bidirectional screws 4, which improves the stability of the movement of the mounting base 1. The rotation of the bidirectional screw 4 drives the transmission chain 404 to rotate, so that the rotating transmission chain 404 drives the other set of bidirectional screws 4 to rotate together, which simplifies the operation process and improves work efficiency.

[0035] The damper is installed in the inner cavity of the shock absorber 2, and a round rod is fixedly connected to one end of the damper. A sliding block is movably sleeved on the outer wall of the round rod, and the sliding block is fixedly installed at the bottom of the mounting base 1. A shock absorber spring 201 is movably sleeved on the outer wall of the round rod. When a vertical vibration force is generated from the equipment, the mounting base 1 contracts into the inner cavity of the shock absorber 2, and the sliding block generates pressure and slides along the round rod. One end of the sliding block compresses the shock absorber spring 201. The shock absorber spring 201 can consume the vibration force in the deformation buffer. At the same time, in cooperation with the damper, it can reduce the reaction force from the shock absorber spring 201, thereby achieving the effect of shock absorption.

[0036] The outer wall of the shock absorber 2 has a connection port 202, which allows the user to access the inner cavity of the shock absorber 2. The inner wall of the connection port 202 is rotatably connected to a baffle 203 via a rotating shaft, which closes the connection port 202 and restricts the position of the shock absorber spring 201.

[0037] The base 3 has a movable opening 301 at the top, and the bottom of the shock absorber 2 is movably engaged in the movable opening 301. When the baffle 203 is located in the inner cavity of the movable opening 301, the inner wall of the movable opening 301 restricts the baffle 203 to prevent the baffle 203 from unfolding outward.

[0038] The bottom of base 3 is fixed with a rubber pad. The rubber pad is made of elastic material, which can first absorb a portion of the vibration force during the vibration of the equipment, thereby reducing the vibration burden.

[0039] Specifically, the working principle and operation method of this utility model are as follows:

[0040] In use, the user holds the adjusting rod 403 and rotates it clockwise. This clockwise rotation of the adjusting rod 403 drives the bidirectional screw 4 to rotate clockwise, causing the two sets of moving blocks 401 to move closer together along the outer wall of the bidirectional screw 4. The two sets of moving blocks 401 push the two sets of push rods 402, causing them to rotate and push the shock absorber 2 upwards. The upward movement of the shock absorber 2 then drives the mounting base 1 upwards, allowing adjustment of the mounting base 1's height to accommodate different axis heights. This ensures proper adjustment of the clearance between the bearing and mechanical parts, thereby improving performance. This improves the adaptability and flexibility of the equipment. Since there are multiple sets of positioning holes 406 corresponding to different limiting positions, when the mounting base 1 moves to the corresponding height position, the rotation of the adjusting rod 403 is stopped. The corresponding positioning hole 406 is aligned with the threaded groove on the fixing block 407. By rotating the positioning screw 408, the positioning screw 408 moves along the threaded groove towards the positioning plate 405, so that the positioning screw 408 is inserted into and locked in the positioning hole 406, thereby fixing the position of the positioning plate 405 and fixing the position of the bidirectional screw 4. This makes the mounting base 1 stable at the height position, which is convenient for use.

[0041] During use, as the adjusting rod 403 is rotated, the shock absorber 2 moves upward. The upward movement of the shock absorber 2 causes the baffle 203 to move upward, allowing the baffle 203 to move out of the base 3. At this point, the inner wall of the moving port 301 can no longer restrict the baffle 203. By rotating the baffle 203 downward, the connection port 202 is opened, allowing the user to easily access the shock absorber spring 201 for replacement. This extends the service life of the shock absorber bearing seat and ensures that the shock absorber bearing seat always maintains a good working condition. When a vertical vibration force is generated from the equipment, the mounting base 1 contracts into the inner cavity of the shock absorber 2. Its sliding block generates pressure and slides along the round rod. One end of the sliding block compresses the shock absorber spring 201. The shock absorber spring 201 can absorb the vibration force during deformation buffering. At the same time, in conjunction with the damper, it can reduce the reaction force from the shock absorber spring 201, thereby achieving the effect of shock absorption.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
