Description

Technical Field

[0001] This utility model relates to the technical field of brake auxiliary devices, and in particular to a novel oil-leakage-proof wet brake. Background Technology

[0002] As is well known, braking systems are crucial for mechanical equipment in modern industry, and wet brakes, as a key type of braking device, play an important role in many industries. A leak-proof wet brake is a braking device that transmits braking force through hydraulic oil while preventing oil leakage. It mainly consists of a brake drum, brake disc, brake pads, piston, cylinder, and seals. When braking is required, the hydraulic system injects pressurized oil into the cylinder. The pressurized oil pushes the piston, which in turn pushes the brake pads to press against the brake disc. The friction between the brake pads and the brake disc generates braking force, stopping the brake drum from rotating, thus achieving braking of the equipment.

[0003] Existing wet brakes have been found to use traditional methods such as welding or flange connections to fix the cylinder and drive motor together. When the brake fails, it is almost impossible to disassemble and repair it quickly, and the whole unit must be replaced, which increases the cost of use and reduces the convenience of the device, resulting in poor practicality.

The right end of the cylinder 2 is connected to the left end of the annular plate 6. The outer side of the rotating shaft 3 is fitted to the inner side of the annular plate 6. The right end of the annular plate 6 is provided with an annular groove. The left end of the annular groove of the annular plate 6 is slidably fitted to the left end of the first annular block 7 via the buffer assembly. The right end of the first annular block 7 is connected to the left end of the second annular block 8. The right end of the second annular block 8 is connected to the left end of the drive motor 1 via the positioning assembly. Four sets of first locking blocks 5 are evenly arranged on the right side of the outer side of the rotating shaft 33. The right end of the mounting block 4 is connected to the left output end of the drive motor 1. The left end of the mounting block 4 is provided with a groove, and four sets of locking slots are evenly arranged on the left side of the groove of the mounting block 4.

[0023] By setting up a connecting mechanism, the drive motor and the cylinder are effectively connected, facilitating the transmission of power between them. The various components in the connecting mechanism work together to make the connection between the drive motor and the cylinder more stable and reliable. At the same time, this modular connection method facilitates installation and disassembly, greatly improving the maintenance efficiency of the equipment and reducing maintenance costs. Moreover, the assembled structure of the annular plate and the rotating shaft helps to ensure the smoothness of rotation and reduce energy loss, thus enhancing practicality.

[0024] As a preferred embodiment of the above, the buffer assembly includes multiple sets of damping rods 9 and multiple sets of connecting springs 10. The left end of the annular groove of the annular plate 6 is uniformly connected to the left end of the multiple sets of damping rods 9, the left end of the first annular block 7 is uniformly connected to the right end of the multiple sets of damping rods 9, and a set of connecting springs 10 is respectively provided on the outer side of the multiple sets of damping rods 9. The left end of the first annular block 7 and the annular groove of the annular plate 6 are slidably fitted together.

[0025] The damping rod can dissipate vibration energy, reduce the impact of vibration on the connection parts, and prevent loosening of the connection and damage to the parts caused by vibration. The connecting spring can undergo elastic deformation when subjected to impact, further absorbing and dispersing energy, protecting the entire connection mechanism, and extending the service life of the equipment.

[0026] As a preferred embodiment of the above, the positioning assembly includes four sets of positioning plates 11 and four sets of connecting screws 12. The right end of the second annular block 8 is evenly provided with four sets of slots. The left ends of the four sets of positioning plates 11 are respectively slidably engaged with a set of slots in the second annular block 8. The left end of the drive motor 1 is evenly connected to the right ends of the four sets of positioning plates 11. The four sets of positioning plates 11 are respectively provided with a set of threaded holes through the corresponding slots in the second annular block 8. One end of the four sets of connecting screws 12 is threadedly connected to the positioning plates 11 and the second annular block 8 through the threaded holes.

[0027] The four sets of positioning plates slide and engage with the slots of the second annular block, which can quickly determine the installation position of the drive motor and improve installation efficiency. The positioning plates and the second annular block are threaded together by connecting screws, making the connection more secure and able to withstand greater torque and tension. This ensures the relative position between the drive motor and the cylinder is stable during operation, avoiding displacement and loosening, thus ensuring the stability and reliability of the braking effect and enhancing practicality.

[0028] As a preferred embodiment of the above, it further includes two sets of guide blocks 13.

[0032] As a preferred embodiment of the above, the inner wall of the annular groove of the annular plate 6 is subjected to surface hardening treatment; the surface hardening treatment can improve the wear resistance of the inner wall of the annular groove, extend the service life of the annular plate, and ensure the normal operation of the buffer assembly.

[0033] As a preferred embodiment of the above, the threads of the four sets of connecting screws 12 are fine threads; compared with ordinary threads, fine threads can provide greater preload under the same tightening torque, making the connection more secure and effectively preventing the connecting screws from loosening.

[0034] This utility model discloses a novel leak-proof wet brake. When disassembly is required during operation, the operator holds the four sets of rotating handles and rotates them counterclockwise to unscrew the connecting screws from the threaded holes of the positioning plates and the second annular blocks. After the connecting screws are fully unscrewed, the operator pulls the drive motor to slide the four sets of positioning plates out of the slots at the right end of the second annular blocks until the rotating shaft drives the four sets of first locking blocks and mounting block grooves to disengage, thus completing the disassembly. Before completing the above actions, the brake is first moved to the position required by the user.
