Description

Technical Field

[0001] The utility model relates to the field of electric motors, in particular to a three-phase synchronous high-efficiency permanent magnet direct-drive electric motor. Background Art

[0002] Permanent magnet DC motors can be divided into permanent magnet brushless DC motors and permanent magnet brushed DC motors according to whether they have brushes or not. Permanent magnet DC motors are DC motors that use permanent magnets to establish a magnetic field. With the development of technology, permanent magnet DC motors have been widely used in the market. Currently, they are directly installed on equipment to work directly. However, when the motor is installed on equipment with high vibration intensity such as a screening machine, after the screening machine has been running for a long time, the motor will be affected by the vibration generated by the screening machine, causing the connection between the front cover and the rear cover of the motor to loosen, thereby affecting the normal operation of the motor. In order to ensure the long-term stable operation of the motor, the motor needs to be buffered and shock-absorbing. Utility Model Content

[0003] In order to solve the technical problem that after the screening machine has been running for a long time, the motor may be vibrated by the screening machine, causing the connection between the front cover and the rear cover of the motor to loosen, thereby affecting the normal operation of the motor, the utility model provides a three-phase synchronous high-efficiency permanent magnet direct-drive motor.

[0004] The utility model adopts the following technical solutions: a three-phase synchronous high-efficiency permanent magnet direct-drive motor, including a direct-drive motor body, and a shock-absorbing frame mechanism including:

[0005] A support plate, the support plate is installed at the bottom end of the shock absorbing frame mechanism to support the shock absorbing frame mechanism body;

[0006] A mounting block connected above the supporting plate;

[0007] The shock absorbing spring device has two ends connected by a mounting block; the shock absorbing spring device is composed of a group of telescopic rods and a winding spring, and the spring is wound on the surface of the telescopic rod;

[0008] A connecting sleeve, the connecting sleeve is sleeved on the surface of the shock absorbing spring;

[0009] A connecting frame, one end of which is connected to the connecting sleeve, and the other end of which is connected to the loading platform. The direct drive motor body is installed above the loading platform, and the supporting buffer mechanism is installed above the loading platform.

[0010] When the main body of the direct-drive motor vibrates, the vibration is transmitted to the shock-absorbing frame mechanism, and the shock-absorbing spring device inside the shock-absorbing frame mechanism vibrates synchronously. The shock-absorbing spring device is composed of a group of telescopic rods and wound springs. The springs are wound on the surface of the telescopic rods. The shock-absorbing spring device buffers the vibration, eliminates the vibration transmitted to the shock-absorbing frame mechanism, and ensures the stability of the supporting buffer mechanism installed above it.

[0011] As a further improvement of the above solution, a support buffer mechanism is provided on the outer side of the direct drive motor body, and a shock absorbing frame mechanism is installed below the support buffer mechanism, and the support buffer mechanism includes:

[0012] A mounting plate, the mounting plate is installed at the bottom end of the supporting buffer mechanism and supports the supporting buffer mechanism as a whole; a reciprocating motor, the reciprocating motor is connected to the outside of the mounting plate; a driving screw, the driving screw is movably connected to the outside of the reciprocating motor; a limit plate, the bottom end of the limit plate is connected to the driving screw, and the limit plate moves with the rotation of the driving screw; a buffer spring column, one end of the buffer spring column is connected to the limit plate, and the other end of the buffer spring column overlaps the surface of the direct drive motor body.

[0013] As a further improvement of the above solution, two groups of limiting plates are provided in a relative shape, and the inner sides of the two groups of limiting plates are connected with relatively installed buffer spring columns, and the direct drive motor body is limited on the inner sides of the buffer spring columns.

[0014] As a further improvement of the above scheme, the direct-drive motor body is installed above the shock absorber frame mechanism, and the supporting buffer mechanism is installed on the outside of the direct-drive motor body. Through the operation of the reciprocating motor, the reciprocating motor immediately drives the driving screw connected to it to rotate synchronously, and the driving screw then drives the limit plate connected to its top to move, and the limit plate thereby drives the buffer spring column connected to its inner side to move synchronously, and the buffer spring column thereby abuts against the direct-drive motor body located on the inner side of the supporting buffer mechanism, and the buffer spring column inside the supporting buffer mechanism abuts against the direct-drive motor body, and the buffer spring column thereby synchronously eliminates vibration.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model shock-absorbing spring device is composed of a group of telescopic rods and a coiled spring. The spring is coiled on the surface of the telescopic rod. The shock-absorbing spring device buffers the vibration, eliminates the vibration transmitted to the shock-absorbing frame mechanism, and ensures the stability of the supporting buffer mechanism installed above it.

[0017] 2. The utility model supports the buffer spring column inside the buffer mechanism to abut against the main body of the direct drive motor, and the buffer spring column eliminates vibration synchronously. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] When the direct-drive motor body 1 vibrates, the vibration is transmitted to the shock-absorbing frame mechanism 2, and the shock-absorbing spring device 23 inside the shock-absorbing frame mechanism 2 vibrates synchronously. The shock-absorbing spring device 23 is composed of a group of telescopic rods and wound springs. The springs are wound on the surface of the telescopic rods. The shock-absorbing spring device 23 buffers the vibration, eliminates the vibration transmitted to the shock-absorbing frame mechanism 2, and ensures the stability of the supporting buffer mechanism 3 installed above it.

[0035] A driving screw 33, the driving screw 33 is movably connected to the outer side of the reciprocating motor 32;

[0036] A limit plate 34, the bottom end of which is connected to the driving screw 33, and the limit plate 34 moves as the driving screw 33 rotates;

[0037] The buffer spring column 35 has one end connected to the limit plate 34, and the other end of the buffer spring column 35 is overlapped on the surface of the direct drive motor body 1. The limit plate 34 is provided with two groups in a relative shape, and the inner sides of the two groups of limit plates 34 are connected with the buffer spring columns 35 installed oppositely, and the direct drive motor body 1 is limited on the inner side of the buffer spring column 35.

[0038] The direct-drive motor body 1 is installed above the shock-absorbing frame mechanism 2, and the supporting buffer mechanism 3 is installed on the outside of the direct-drive motor body 1.

The shock-absorbing spring device 23 is composed of a group of telescopic rods and wound springs, and the springs are wound on the surface of the telescopic rods. The shock-absorbing spring device 23 buffers the vibration and eliminates the vibration transmitted to the shock-absorbing frame mechanism 2, thereby ensuring the stability of the supporting buffer mechanism 3 installed above it. At the same time, a buffer spring column 35 is connected to the outer side of the direct-drive motor body 1, and the buffer spring column 35 eliminates the vibration synchronously.
