Description

Technical Field

[0001] The utility model relates to the technical field of motor transmission centers, in particular to a locking mechanism for a motor transmission center. Background Art

[0002] The motor drive center generally refers to the connection point or alignment center between the motor shaft and the driven load such as gears, pulleys, couplings, etc. This point or center is the key position for the motor to transmit rotational power and torque to downstream equipment. It is necessary to ensure precise alignment and stable connection to achieve efficient energy transfer and reduce mechanical vibration or wear.

[0003] The existing motor transmission center locking mechanism mainly uses a holding brake for braking. Although this braking method is effective, it requires a long response time to fix the motor rotor in a certain position, the response speed is slow, the braking effect is poor, and the brake pads are greatly worn during braking, resulting in the need for frequent replacement and maintenance of the brake pads. Therefore, it is necessary to provide a new locking mechanism for the motor transmission center. Utility Model Content

A cylinder is arranged on one side of the mounting frame, and the output end of the cylinder is connected to one end of the connecting rod.

[0009] By adopting the above technical solution, the base serves as the supporting foundation of the entire mechanism, providing a stable working environment, ensuring that the motor and transmission mechanism can operate smoothly, and the motor can be disassembled and connected to the base through a fixing frame, which facilitates the installation and disassembly of the motor and facilitates maintenance and replacement.

[0010] Furthermore, the electromagnetic plate and the copper sheet are used to perform electromagnetic damping on the main shaft.

[0011] By adopting the above technical solution, through the interaction between the electromagnetic plate and the copper sheet, the magnitude of the damping force can be accurately controlled to meet the braking requirements under different working conditions.

[0012] Furthermore, the wear-resistant ring can reduce the direct contact between the brake pad and the copper sheet, reduce the degree of wear, and extend the service life of the brake pad.

[0013] By adopting the above technical solution, electromagnetic damping can effectively slow down the rotation speed of the main shaft, achieve rapid braking, and improve the safety and reliability of the equipment.

[0014] Furthermore, the wear-resistant ring is made of high manganese steel, and the brake pad is made of polymer material.

[0015] By adopting the above technical solution, the wear-resistant ring can reduce the direct contact between the brake pad and the copper sheet, reduce the degree of wear, and extend the service life of the brake pad.

[0016] Furthermore, disassembly seats are provided on both sides of the top of the base, and the disassembly seats are fixedly connected to the base by bolts.

[0018] Furthermore, a plurality of disassembly seats are provided, and a driven rod is rotatably connected between the plurality of disassembly seats.

[0019] By adopting the above technical solution, the provision of the disassembly seat facilitates the installation and disassembly of the driven rod, and is convenient for the maintenance and replacement of parts of the equipment.

[0020] Furthermore, a driven gear is provided on the driven rod, and the driven gear is meshed with the driving gear through a toothed belt.

[0021] By adopting the above technical solution, the linkage between the driven rod and the main shaft is achieved through the meshing transmission of the toothed belt, so that the equipment can transmit power and rotational motion.

[0022] Furthermore, the driven rod and the disassembly seat are provided in two groups, and the two groups of the driven rod and the disassembly seat are mirror-imaged along the central axis of the base.

[0023] By adopting the above technical solution, the arrangement of two sets of driven rods increases the transmission capacity and stability of the equipment, can balance the load, and reduce vibration and deformation.

[0024] Furthermore, the base is made of aluminum alloy, and the fixing frame is made of stainless steel.

[0025] By adopting the above technical solution, the aluminum alloy base has a light weight and good corrosion resistance, and is easy to carry and install.

[0026] Furthermore, a circuit line is provided on the outer side of the holding ring, and the circuit line is used to supply power to the electromagnetic plate.

[0027] By adopting the above technical solution, the setting of the circuit line ensures that the electromagnetic plate can stably and reliably receive electrical energy and realize the electromagnetic damping function.

[0028] In summary, the utility model mainly has the following beneficial effects:

[0029] 1. The utility model sets a braking mechanism, in which the mounting frame provides stable support, and the cylinder realizes precise control of the holding ring and the brake pad through the connecting rod and two movable rods. When the cylinder works, it can quickly drive the movable rod to clamp inward, so that the brake pad is closely attached to the main shaft, thereby realizing rapid braking. This design not only has a good braking effect, but also has a fast response speed, greatly improving the safety and working efficiency of the equipment. When the electromagnetic plate is energized, it will generate electromagnetic force between it and the copper sheet, and this electromagnetic force can produce a damping effect on the rotation of the main shaft, so that the main shaft can be decelerated and stopped faster. Compared with the traditional mechanical braking method, the electromagnetic damping brake has the advantages of less wear, long service life, and smooth braking.

[0030] 2. The utility model provides a wear-resistant ring, which can effectively reduce the direct contact between the brake pad and the spindle due to its high wear resistance, thereby reducing the wear between the two parts. This reduced wear extends the service life of the brake pad and the spindle, reduces the need for frequent replacement and maintenance, and at the same time, the presence of the wear-resistant ring can ensure that the friction coefficient between the brake pad and the spindle remains relatively stable during the braking process, which means that after multiple braking operations, the braking performance will not decrease significantly, thereby improving the reliability of the entire locking mechanism.

The circuit line 11 arranged on the outside of the holding ring 904 provides a stable power supply for the electromagnetic plate 907, ensuring the normal operation of the electromagnetic damping device and improving the braking performance and reliability of the equipment.

[0050] The implementation principle of the utility model is as follows: first, the base 1 needs to be placed in an appropriate position, and the disassembly seat 6 is fixed to both sides of the top of the base 1 with bolts, the motor 3 is disassembled and connected to the middle position of the top of the base 1 through the fixing frame 2, the support frame 4 is ensured to be fixedly connected to the base 1, and one end of the main shaft 501 is rotatably connected to the support frame 4;

[0051] The mounting frame 901 of the brake mechanism 9 is set on the outside of the main shaft 501, and the movable rod 903 is connected to the cylinder 902 through the connecting rod 909, and the ring 904 is rotatably connected to the inside of the movable rod 903, and the brake pad 910 is set on the inside of the ring 904.

[0052] When the locking mechanism needs to be activated during use, the connecting rod 909 is driven by controlling the cylinder 902 to force the two movable rods 903 to clamp inwardly. The inward clamping action of the movable rod 903 drives the ring 904 and the brake pad 910 to approach the main shaft 501. After the brake pad 910 contacts the main shaft 501, the main shaft 501 is braked by friction. At the same time, the electromagnetic plate 907 generates electromagnetic force after being energized, which interacts with the copper plate 906 to form electromagnetic damping, further enhancing the braking effect.

[0053] When the brake is in contact, the control cylinder 902 moves the connecting rod 909 and the movable rod 903 outward, thereby releasing the brake on the main shaft 501.
