Description

Technical Field

[0001] This utility model relates to the technical field of springs, shock absorbers, and vibration damping devices, specifically a rubber shear spring assembly. Background Technology

[0002] A vibrating screen is a screening device that uses mechanical vibration to classify, filter, or dewater materials. It is widely used in industries such as mining, metallurgy, building materials, and chemicals. The centrifugal force generated by the vibrating motor or exciter causes the screen box to vibrate periodically, and the material is thrown, layered, and passes through the screen. Rubber shear springs are a special damping element in vibrating screen equipment, mainly used for vibration reduction and anti-resonance of high-frequency vibrating equipment.

[0003] Rubber shear springs are composed of a rubber body and metal components (such as steel plates). They absorb vibration energy through the shear deformation of the rubber layer. Under continuous vibration, the adhesion between the rubber block and the steel plate is easily reduced, making it easy for the steel plates at both ends of the shear spring to detach from the spring, causing the rubber block to fall off, which in turn affects the performance of the vibrating screen. Utility Model Content

[0009] Preferably, the upper side of the steel plate has four bolt holes arranged in a rectangular array, and the lower side of each of the four bolt holes extends out of the steel plate.

[0014] Preferably, the two limiting sockets are respectively aligned with the two sliding holes, and the two sliding rods are respectively fixedly connected to the right side of the connecting block;

[0032] Please see Figure 1-4This utility model provides a new technical solution: a rubber shear spring assembly, including a rubber body 1, with steel plates 3 fixedly connected to both the upper and lower sides of the rubber body 1. The connection structure between the rubber body 1 and the two steel plates 3 is identical and symmetrically arranged vertically. The following description focuses on the upper steel plate 3. Five protrusions 2 are fixedly connected to the upper side of the rubber body 1, arranged in a cross shape. Five protrusion grooves 4 are formed on the lower side of the steel plate 3, each groove matching one of the five protrusions 2, increasing the adhesive area and thus improving the bonding strength between the rubber body 1 and the steel plate 3. Four bolt holes 5 are provided on the upper side, arranged in a rectangular array. A steel plate 3 extends from the lower side of each of the four bolt holes 5. Four fixing bolts 6 are installed on the lower side of the steel plate 3, extending through the four bolt holes 5. The steel plate 3 is connected to the vibrating screen by the four fixing bolts 6. A fixing structure is provided on the steel plate 3, which can further fix the rubber body 1 and the steel plate 3 together. The fixing mechanism includes a connecting block groove 7, a connecting block 8, two sliding insertion holes 9, two limit insertion ports 10, two sliding rods 11, a mounting groove 12, and mounting bolts 13.

[0033] Furthermore, the connecting block groove 7 is opened on the left side of the steel plate 3, the connecting block 8 is slidably connected to the inside of the connecting block groove 7, two sliding holes 9 are both opened on the right wall of the connecting block groove 7, the right side of the two sliding holes 9 extends into the inside of the steel plate 3, the right side of the two sliding holes 9 respectively passes through the front and rear protrusion grooves 4, two limiting sockets 10 are respectively opened on the left side of the front and rear protrusions 2, the two limiting sockets 10 respectively extend through the right side of the two protrusions 2, the two limiting sockets 10 are respectively opposite to the two sliding holes 9, two sliding rods 11 are respectively fixedly connected to the right side of the connecting block 8, the right end of the two sliding rods 11 respectively slides into the inside of the two sliding holes 9, the right end of the two sliding rods 11 respectively slides through the two limiting sockets 10, the mounting groove 12 is opened on the left side of the connecting block 8, the mounting bolt 13 is installed inside the mounting groove 12, the right end thread of the mounting bolt 13 passes through the connecting block 8, and the right end thread of the mounting bolt 13 extends into the inside of the steel plate 3.

[0034] Furthermore, when starting work, first apply adhesive to the upper side of the protrusion 2 and the rubber body 1, then place the steel plate 3 on the upper side of the rubber body 1, at which point the protrusion 2 and the protrusion groove 4 are facing each other, and wait until the protrusion 2 and the protrusion groove 4, and the upper side of the rubber body 1 and the lower side of the steel plate 3 are firmly bonded.

[0035] Furthermore, slide the connecting block 8 into the connecting block groove 7 on the left side of the steel plate 3, push the connecting block 8 so that the two sliding rods 11 on the right side of the connecting block 8 are respectively inserted into the sliding insertion holes 9, and after passing through the protrusion groove 4, they are inserted into the limiting insertion port 10 on the protrusion 2. Finally, screw the mounting bolt 13 into the mounting groove 12 and screw it into the inside of the steel plate 3. By tightening the mounting bolt 13, the connecting block 8 is firmly fixed on the steel plate 3, so that the sliding rods 11 are tightly stuck in the protrusion 2, thereby further fixing the rubber body 1 and the steel plate 3, preventing relative displacement between the two during vibration, and ensuring that the rubber shear spring assembly always maintains good shock absorption performance.

[0036] By passing four fixing bolts 6 through the bolt holes 5 on the steel plate 3, it is fixedly connected to the vibrating screen to ensure that the component is installed firmly. Between the rubber body 1 and the steel plate 3, five cross-shaped protrusions 2 are embedded in the corresponding protrusion grooves 4 on the lower side of the steel plate 3, which increases the adhesive area between the two and initially achieves a firm connection.

[0037] When the vibrating screen vibrates during operation, the vibration force is transmitted to the steel plate 3. The steel plate 3 causes the rubber body 1 connected to it to undergo shear deformation. The rubber body 1 absorbs and buffers the vibration energy with its own good elasticity and flexibility, reducing the impact of vibration on the equipment.

[0038] Furthermore, this method ensures a secure connection between the rubber body 1 and the steel plate 3, making it less likely for the rubber body 1 to detach and improving the service life of the rubber shear spring.

[0039] Structural Description: Rubber Body 1: As the core elastic component of the spring assembly, when subjected to vibration force, rubber body 1 will undergo shear deformation. With its own good elasticity and flexibility, it absorbs and buffers vibration energy, reducing the impact of vibration on the equipment.

[0040] Protrusion 2: Five protrusions 2 are fixedly connected to the upper side of the rubber body 1, arranged in a cross shape. They are embedded in the corresponding protrusion grooves 4 on the lower side of the steel plate 3, increasing the adhesive area between the rubber body 1 and the steel plate 3, and initially achieving a firm connection.

[0041] Steel plate 3: There are two steel plates 3, which are fixedly connected to the upper and lower sides of the rubber body 1 respectively. As a connecting component, the steel plate 3 is connected to the rubber body 1 by adhesive and fixing mechanism on the one hand, and to the vibrating screen by fixing bolts 6 on the other hand, so as to transmit the vibration force to the rubber body 1, and at the same time play the role of fixing and supporting.

[0042] The bump groove 4 is located on the underside of the steel plate 3 and is adapted to the bump 2 on the upper side of the rubber body 1. The fit between the bump groove 4 and the bump 2 increases the adhesive area and improves the bonding strength between the rubber body 1 and the steel plate 3. There are five bump grooves 4, and the five bump grooves 4 are distributed in a cross shape.

[0043] Bolt holes 5: These are located on the upper side of the steel plate 3, arranged in a rectangular array, and extend from the lower side of the steel plate 3. The bolt holes 5 are used to pass through the fixing bolts 6 to connect the steel plate 3 to the vibrating screen.

[0044] Fixing bolts 6: Four fixing bolts 6 extend through four bolt holes 5 respectively, and the steel plate 3 is fixedly connected to the vibrating screen by fixing bolts 6 to ensure that the component is installed securely.

[0045] Connecting block groove 7: It is opened on the left side of steel plate 3 and is used to slide the connecting block 8 to provide installation space for the fixing mechanism.

[0046] Connecting block 8: It is slidably connected inside the connecting block groove 7. The two sliding rods 11 on the right side of the connecting block 8 are respectively inserted into the sliding insertion hole 9, and after passing through the protrusion groove 4, they are inserted into the limiting insertion port 10 on the protrusion 2. They are fixed to the steel plate 3 by the mounting bolt 13, which further fixes the rubber body 1 and the steel plate 3.

[0047] Sliding insertion hole 9: It is formed on the right wall of the connecting block groove 7, extends into the interior of the steel plate 3 on the right side, and passes through the front and rear protrusion grooves 4 respectively. The sliding insertion hole 9 provides a sliding channel for the sliding insertion rod 11, so that the sliding insertion rod 11 can be inserted into the limiting insertion hole 10 on the protrusion 2.

[0048] Limiting sockets 10: These are respectively opened on the left side of the two front and rear protrusions 2 and extend beyond the right side of the two protrusions 2. The limiting sockets 10 are opposite to the sliding sockets 9 and are used to accommodate the sliding rods 11. The cooperation between the sliding rods 11 and the limiting sockets 10 prevents relative displacement between the rubber body 1 and the steel plate 3 during vibration.

[0049] Sliding rod 11: Fixedly connected to the right side of connecting block 8, with its right end slidingly extending into the interior of two sliding holes 9 and through two limiting sockets 10. The sliding rod 11 serves to hold the protrusion 2 in place, further securing the rubber body 1 and the steel plate 3.

[0050] Mounting slot 12: Located on the left side of connecting block 8, used for mounting bolt 13.

[0051] Mounting bolt 13: Installed inside the mounting groove 12, with the right end threaded through the connecting block 8 and extending into the interior of the steel plate 3. By tightening the mounting bolt 13, the connecting block 8 is firmly fixed to the steel plate 3, so that the sliding rod 11 tightly locks the protrusion 2, thereby further fixing the rubber body 1 and the steel plate 3.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
