Description

Technical Field

[0001] The present invention belongs to the field of electromagnetic clutches, and relates to an installation structure and method for a rolling mill screw-down electromagnetic clutch. Background Art

[0002] Electromagnetic clutches are widely used in mechanical drive systems. They mainly achieve the connection and disconnection between two mechanical components through electromagnetic force, and are commonly found in rolling and automated production line applications. Their core advantage lies in providing fast and smooth start-stop performance through electromagnetic control.

[0003] However, the disassembly, installation, coaxiality, and meshing clearance adjustment of electromagnetic clutches have always been difficult points in traditional technologies. Especially when maintenance or replacement is required, the precision adjustment of electromagnetic clutches and the complexity of mechanical structures increase the difficulty of maintenance.

[0004] During the use of equipment, especially in systems involving friction elements, the loss of precision due to wear often occurs. As a high-load component, the electromagnetic clutch will be worn after long-term use, resulting in coaxiality deviation and inaccurate meshing clearance, affecting equipment performance and even causing failures.

[0005] In order to improve the reliability of equipment, effective technical means are needed to prevent the loss of precision of the clutch due to wear, and a new adjustment scheme is proposed to solve this problem. Summary of the Invention

[0006] To overcome the defects in the above related technologies, on the one hand, the present invention proposes an installation structure for a rolling mill screw-down electromagnetic clutch.

[0007] The installation structure for a rolling mill screw-down electromagnetic clutch described in the present invention is applicable to a jaw-type electromagnetic clutch. The jaw-type electromagnetic clutch includes an exciting coil and a friction wheel. A first blind hole is provided on the side wall of the exciting coil, and a second blind hole is provided on the side wall of the friction wheel; The installation structure for the rolling mill screw-down electromagnetic clutch includes: A first locking piece, the first locking piece includes a first bottom plate and a first vertical plate. The first bottom plate is a plate adapted to the arc of the side wall of the exciting coil. Two through holes are provided on the first bottom plate. The first vertical plate is a vertical plate. A through groove is provided on the first vertical plate. The first vertical plate is fixedly connected to one side of the upper end surface of the first bottom plate. The first bottom plate and the first vertical plate form an L-shaped structure. The first locking piece is fixedly connected to the exciting coil; The second locking piece, the second locking piece includes a second bottom plate and a second vertical plate. The second bottom plate is a plate adapted to the arc of the side wall of the friction wheel. Two through holes are provided on the second bottom plate. The second vertical plate is a vertical plate, and a through groove is provided on the second vertical plate. The second vertical plate is fixedly connected to one side of the upper end surface of the second bottom plate. The second bottom plate and the second vertical plate form an L-shaped structure. The second locking piece is fixedly connected to the friction wheel; The fastening bolt passes through the through groove of the first vertical plate and the through groove of the second vertical plate, and the first vertical plate and the second vertical plate are attached and fixedly connected.

[0008] On the other hand, the present invention also provides an installation method for a rolling mill screw-down electromagnetic clutch, which is applicable to the installation structure of the above rolling mill screw-down electromagnetic clutch. The installation method of the rolling mill screw-down electromagnetic clutch includes: Separate the electromagnetic clutch housing; Fix the first locking piece to the side wall of the exciting coil; Energize the exciting coil and attract the friction wheel so that the gap between the exciting coil and the friction wheel is zero; Fix the second locking piece on the side wall of the friction wheel, and fixedly connect the first locking piece and the second locking piece to fix the exciting coil and the friction wheel; De-energize the exciting coil and separate the second locking piece from the friction wheel; Remove the friction wheel and replace it with a new one; Fix the second locking piece to the new friction wheel, and control the axial and radial deviations within 0.05 mm through the adjusting nut on the friction wheel side.

[0009] The top clearance is the sum of the side play of the synchronizing shaft, the side play of the screw-down speed reducer and 1.5 mm. The meshing clearance after the friction wheel is installed meets the requirements of the top clearance.

[0010] The beneficial effects of the present invention are as follows: Improve the installation and disassembly efficiency: Traditional electromagnetic clutches are difficult to install and disassemble, especially difficult to disassemble when the clutch is in the meshing state, which affects the maintenance efficiency of the equipment. The design of this project makes the clutch more convenient to install and disassemble through an innovative locking device and an improved structural design, reducing the operation difficulty.

[0011] Ensure the precise adjustment of coaxiality and meshing clearance: The coaxiality and meshing clearance of the electromagnetic clutch are crucial for the long-term stable operation of the equipment. Especially in the case of wear, it is difficult to maintain precision by traditional methods. The design of this project improves the clutch structure to precisely control the coaxiality and meshing clearance, ensuring that it can still maintain good working performance during long-term use.

[0012] Improve the reliability and stability of equipment operation: By precisely adjusting the coaxiality and meshing clearance of the clutch, prevent the abnormal opening and closing of the clutch caused by deviation, avoid the problem of abnormal opening under the action of axial force, thereby improving the operation stability of the equipment, and ensuring that the electromagnetic clutch can reliably complete the start-stop operation during normal production.

[0013] Prolong the service life of the equipment and reduce the maintenance frequency: Through reasonable design and precise adjustment, reduce the damage caused by wear, prolong the service life of the electromagnetic clutch, and reduce the downtime caused by frequent maintenance and replacement, improving production efficiency and equipment availability.

[0014] Reduce maintenance costs and improve production efficiency: By optimizing the installation and adjustment methods of the clutch, reduce the incidence of equipment failures, and avoid production downtime caused by difficult maintenance. This can reduce maintenance costs while increasing the normal operating time and production efficiency of the equipment. Brief Description of the Drawings
