Description

Technical Field

[0001] The utility model relates to the technical field of elevator equipment, in particular to a synchronous motor rotor yoke assembly for an elevator. Background Technique

[0002] Synchronous motors are often used as drive devices in elevators, and the rotor yoke assembly is an important part of the synchronous motor. The rotor yoke assembly usually consists of components such as a rotor, a yoke, and bearings. Its function is to transfer the rotational force between the magnetic field generated by the motor and the rotor to the transmission system of the elevator, thereby driving the lifting movement of the elevator. In an elevator, the rotor yoke assembly of the synchronous motor needs to have good wear resistance, high efficiency, and stability to ensure the safety and reliability of the elevator operation. At the same time, in order to reduce noise and vibration and improve the comfort of the elevator, the design of the rotor yoke assembly also needs to consider reducing gaps and optimizing the structure.

[0003] The prior art can connect the elevator rotor to a yoke of corresponding size. However, after the rotor is used for a long time, the connection structure will wear, which requires replacing the yoke to ensure the normal use of the elevator, and replacing the yoke is rather troublesome. Therefore, those skilled in the art have provided a synchronous motor rotor yoke assembly for an elevator to solve the problems raised in the above background technique. Summary of the Invention

[0004] The purpose of the utility model is to provide a synchronous motor rotor yoke assembly for an elevator to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A synchronous motor rotor yoke assembly for an elevator includes a rotor shaft, a machine base, an outer ring, an adjusting cover, and a rotating ring. A first slot is provided at the upper end of the machine base. A magnetic field winding is provided at the middle position of the first slot. A coupling sleeve is fixedly connected in the middle of the magnetic field winding. The coupling sleeve is fixedly connected to the machine base. A number of groups of second card slots are provided on the outer surface of the coupling sleeve. An annular groove is provided outside the coupling sleeve. The annular groove is connected to the second card slots and divides the second card slots into two sections. A second slot is provided at the upper end of the coupling sleeve. An adjusting cover is provided above the coupling sleeve. A second insertion ring is provided at the lower end of the adjusting cover. The second insertion ring is inserted into the second slot. A number of groups of second clamping blocks are provided around the second insertion ring. The second clamping blocks are clamped in the second card slots. First grooves are provided on the second clamping blocks. The first grooves correspond to the connection positions of the annular groove and the second card slots. A rotating ring is rotatably connected in the annular groove.

[0007] As a further solution of the utility model: A plurality of groups of second grooves are arranged on the inner ring of the rotating ring, wherein the second clamping blocks can pass through the second grooves, and by rotating the rotating ring, the rotating ring can be clamped with the first groove. A plurality of groups of first clamping grooves are arranged on the outer side of the first slot, and the first clamping grooves are fixedly arranged on the machine base.

[0008] As a further solution of the utility model: An outer ring is inserted into the first slot. A plurality of groups of connecting holes are arranged at the upper end of the outer ring. A plurality of groups of first clamping blocks are fixedly connected to the outer surface of the outer ring, and the first clamping blocks are clamped in the first clamping grooves.

[0009] As a further solution of the utility model: A plurality of groups of spring rods are arranged inside the outer ring. One ends of the spring rods are inserted into the outer ring respectively, and the other ends of the spring rods are fixedly connected with arc-shaped plates. A rubber layer is arranged on the front surface of the arc-shaped plates, and the rubber layer plays a buffering role.

[0010] As a further solution of the utility model: An installation shaft groove is arranged in the middle of the coupling sleeve. A rotor shaft is inserted into the installation shaft groove, and the rotor shaft is rotationally connected to the coupling sleeve through a bearing, and the upper end of the rotor shaft passes through the adjusting cover.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. After the adjusting cover is worn to a certain extent, the rotating ring can be rotated to align the second groove with the second clamping block. Then, by pulling the adjusting cover, the second clamping block can be separated from the second clamping groove, and the second insertion ring can be separated from the second slot, so that the adjusting cover can be disassembled from the rotor shaft. When installing a new adjusting cover, the second insertion ring can be inserted into the second slot, the second clamping block can be snapped into the second clamping groove, and by rotating the rotating ring, the rotating ring can be clamped with the first groove, so that the adjusting cover is fixed on the coupling sleeve. In this way, the installation and disassembly are both convenient and fast.

[0013] 2. When the rotor shaft rotates, the coupling sleeve may vibrate accordingly. The arc-shaped plates will clamp the coupling sleeve in the middle. The rubber layer on the front surface of the arc-shaped plates plays a buffering role. At the same time, the spring rods can enhance the buffering effect of the arc-shaped plates, so that the vibration amplitude of the coupling sleeve can be reduced and the damage to the coupling sleeve can be alleviated.

The second clamping blocks 16 are clamped in the second clamping grooves 6. First grooves 17 are provided on the second clamping blocks 16. The first grooves 17 correspond to the connection positions of the annular groove 9 and the second clamping groove 6. A rotating ring 19 is rotatably connected in the annular groove 9. A plurality of groups of second grooves 20 are provided on the inner circle of the rotating ring 19. The second clamping blocks 16 can pass through the second grooves 20. By rotating the rotating ring 19, the rotating ring 19 can be clamped with the first groove 17. A plurality of groups of first clamping grooves 2 are provided outside the first slot 3. The first clamping grooves 2 are fixedly provided on the machine base 1. An outer ring 10 is inserted into the first slot 3. A plurality of groups of connection holes 12 are provided at the upper end of the outer ring 10.

[0022] The working principle of the present utility model is as follows: Firstly, after the adjusting cover 15 wears to a certain extent, the rotating ring 19 can be rotated to align the second groove 20 with the second clamping block 16.
