Description

Technical Field

[0001] This utility model relates to the field of permanent magnet speed controller installation technology, specifically a gap adjustment device for installing a permanent magnet speed controller. Background Technology

[0002] A permanent magnet speed controller is a transmission device that transmits torque through an air gap, primarily used for torque transmission between a motor and a load device. The drive of a permanent magnet speed controller consists of a permanent magnet rotor and a conductor rotor. During installation, the gap between the permanent magnet rotor and the conductor rotor needs to be adjusted to achieve a suitable connection spacing. Existing adjustment methods typically involve directly mounting the permanent magnet rotor and conductor rotor on the input and load shafts respectively, and then adjusting the gap. Since the permanent magnet rotor and conductor rotor are already fixed, adjustment requires loosening and repositioning, which is inconvenient. Therefore, a gap adjustment device for permanent magnet speed controller installation is proposed, which directly adjusts the gap between the permanent magnet rotor and the conductor rotor before installation, making the installation operation much more convenient. Summary of the Invention

[0022] Please see Figures 1-4 In this embodiment of the present invention, a gap adjustment device for installing a permanent magnet speed regulator includes a fixed base 1, a movable base 2 on the outer side of the fixed base 1, and a pressure cover 3 on the top of both the fixed base 1 and the movable base 2. A permanent magnet rotor 4 and a conductor rotor 5 are respectively placed inside the fixed base 1 and the movable base 2. The pressure cover 3 covers the outer side of the corresponding permanent magnet rotor 4 and conductor rotor 5. The pressure cover 3 and the corresponding fixed base 1 and movable base 2 are provided with placement cavities adapted to the permanent magnet rotor 4 and conductor rotor 5. Two guide rods 13 are symmetrically fixedly connected to the bottom of the fixed base 1, and the guide rods 13 slide through it. The movable seat 2 has a circular hole through which the guide rod 13 passes and slides. A threaded handle 14 is provided between the guide rods 13. The thread of the threaded handle 14 passes through the movable seat 2 and the threaded end is rotatably mounted on the fixed seat 1.

The edge of the movable seat 2 points on the scale 6 for reading.

[0023] The permanent magnet rotor 4 and conductor rotor 5 are housed by the fixed seat 1, the movable seat 2 and the pressure cover 3. The movable seat 2 moves relative to the fixed seat 1 by the rotation of the threaded handle 14 and the guidance of the guide rod 13. The gap can be read by the scale 6, thereby realizing the adjustment of the gap. After the adjustment is completed, the adjusted permanent magnet rotor 4 and conductor rotor 5 can be directly fixed to the input end shaft and the load end shaft. There is no need to adjust after fixing the permanent magnet rotor 4 and conductor rotor 5, which makes the gap adjustment more convenient.

[0024] A magnifying glass 7 is fixedly installed on the bottom of the movable base 2 at the corresponding scale 6. The movable base 2 has a notch for mounting the magnifying glass 7, and the fixed base 1 has a clearance notch on the outside for the magnifying glass 7 to avoid. This allows the magnifying glass 7 to be stored when the movable base 2 and the fixed base 1 are in contact with each other.

[0025] The magnifying glass 7 is set to magnify the position of the scale 6 corresponding to the movable seat 2, so as to facilitate the observation of the scale corresponding to the scale 6.

[0026] Both the fixed base 1 and the movable base 2 are fixedly connected to baffles 8 on their opposite sides, and the baffles 8 are in contact with the corresponding permanent magnet rotor 4 and conductor rotor 5.

[0027] By setting the baffle 8, the permanent magnet rotor 4 and conductor rotor 5 placed in the placement cavity on the fixed seat 1 and the movable seat 2 are fitted and positioned.

[0028] One side of the pressure cap 3 is hinged to the fixed seat 1 and the movable seat 2. The other side of the pressure cap 3, together with the fixed seat 1 and the movable seat 2, has a clearance groove. The clearance groove contains a tensioning screw 9. The bottom end of the tensioning screw 9 is rotatably installed in the clearance groove on the corresponding fixed seat 1 and the movable seat 2. The top end of the tensioning screw 9 is threaded with an internal thread shank 10. The internal thread shank 10 presses on the corresponding pressure cap 3. The bottom area of ​​the internal thread shank 10 is larger than the area of ​​the clearance groove.

[0029] The pressure cap 3 is hinged. By rotating the tension screw 9 and the internal threaded handle 10, a compression and limiting effect can be formed, which makes it easy to operate the pressure cap 3 to be combined and fixed with the fixed seat 1 and the movable seat 2.

[0030] The top surface of the pressure cap 3 is also threaded with a clamping bolt 11, and the bottom end of the clamping bolt 11 is fixedly connected with a soft pressure block 12. A hexagonal nut for threaded connection of the clamping bolt 11 is fixedly connected to the pressure cap 3, and the pressure cap 3 is provided with a hole for insertion of the clamping bolt 11.

[0031] A clamping bolt 11 is further threaded onto the pressure cover 3, so that when the permanent magnet rotor 4 and the conductor rotor 5 are installed in the placement cavity on the pressure cover 3, the fixed seat 1 and the movable seat 2, the clamping bolt 11 can drive the soft pressure block 12 to press against the permanent magnet rotor 4 and the conductor rotor 5 to form a squeezing and fixing effect.

[0032] The working principle of this utility model is as follows:

[0033] In use, place the permanent magnet rotor 4 and conductor rotor 5 on the corresponding movable seat 2 and fixed seat 1, so that the permanent magnet rotor 4 and conductor rotor 5 are in contact with the baffle 8. Then, flip the pressure cover 3 so that the pressure cover 3 presses against the movable seat 2 and fixed seat 1, so that the permanent magnet rotor 4 and conductor rotor 5 are squeezed and fixed. Then, flip the tension screw 9 so that the tension screw 9 stands up. Then, rotate the internal thread handle 10 to press against the top surface of the pressure cover 3 to form a squeeze fixation. At this time, the locking bolt 11 can be tightened so that the soft pressure block 12 presses against the corresponding permanent magnet rotor. On the permanent magnet rotor 4 and conductor rotor 5, a compression fixation is further formed. At this time, the threaded handle 14 can be rotated, and with the cooperation of the guide rod 13, the movable seat 2 is driven to move relative to the fixed seat 1, thereby adjusting the gap between the permanent magnet rotor 4 and conductor rotor 5. At this time, the gap size can be read by observing the scale 6 through the magnifying glass 7. The entire device is then placed between the output end shaft and the load end shaft, and the permanent magnet rotor 4 and conductor rotor 5 are connected to the output end shaft and the load end shaft respectively, completing the combined installation of the permanent magnet rotor 4 and conductor rotor 5.
