Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor application technology, specifically relating to a braking device for an integrated magnetized synchronous reluctance roller motor, mainly used for braking and anti-reverse rotation of the integrated magnetized synchronous reluctance roller motor. Background Technology
[0002] The permanent magnet assisted synchronous reluctance frequency converter system consists of a back-mounted, control panel-less driver and a ferrite assisted synchronous reluctance motor (integrated magnetized synchronous reluctance drum motor). It is a high-performance integrated machine, mainly used in factory and large building ventilation fans.
[0003] A motor backstop is a structure (braking device) that prevents a motor from reversing. For example, to prevent reversal or slippage of an inclined belt conveyor when it stops under load, a backstop (braking device) is added depending on the specific situation after calculating the braking torque. Current backstops (braking devices) are more suitable for upward conveying belt conveyors with an inclination angle ≤18 degrees. Their advantages include rapid backstopping and a small reversal distance, making them the first choice for medium and large inclined conveyors. They are also widely used in reducer systems, coking plants, transportation machinery, conveyors, elevators, electric rollers, and other mechanical equipment requiring backstop functionality.
[0004] Based on the applicant's analysis, it is not suitable for use in the brake assembly of an integrated magnetized synchronous reluctance roller motor.
[0005] Therefore, based on the above problems, this utility model provides a braking device for an integrated magnetic auxiliary synchronous reluctance roller motor. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present invention for a braking device for an integrated magnetically assisted synchronous reluctance roller motor are as follows: 1. After assembly, the whole assembly forms a one-way braking structure, which is used to match the shaft slot on the forward rotating shaft to automatically and reliably lock the reverse rotating shaft, preventing the equipment from reversing or turning backward, and eliminating safety problems; 2. The whole assembly is a split design, which is convenient for assembly and disassembly, and the one-way anti-reverse structure can stop the reverse movement in a timely and stable manner.

[0020] Example
[0021] like Figure 1 , Figure 2 and Figure 3The braking device shown is for an integrated magnetically assisted synchronous reluctance roller motor, including a backstop outer circular body 1, a limiting protrusion 12 disposed on the inner wall of the backstop outer circular body 1, an arc-shaped limiting tooth 13 disposed on one end face of the limiting protrusion 12, a grooved backstop inner circular body 4 inserted into the backstop outer circular body 1 and used in conjunction with the limiting protrusion 12 (the grooved backstop inner circular body 4 abuts against the outer walls on both sides of the limiting protrusion 12 to enhance the strength and impact resistance of the limiting protrusion 12), an outer retaining ring gasket 5 and an inner retaining ring gasket 2 disposed in the backstop outer circular body 1 and abutting against both sides of the grooved backstop inner circular body 4, and an outer elastic retaining ring 6 and an inner elastic retaining ring 3 respectively disposed on one side of the outer retaining ring gasket 5 and the inner retaining ring gasket 2.
[0022] The working principle is as follows: After the overall components are assembled, they are matched and installed on the working surfaces of the bearing 300 and the rotating shaft 100, and are fixed by the outer cover surface 7 and the outer cover 8. At this time, the limiting protrusion 12, the arc-shaped limiting protrusion 13 and the rotating shaft arc groove 200 on the rotating shaft 100 are connected.
[0023] When the shaft 100 and the arc groove 200 rotate in the forward direction, the arc groove 200 does not contact the limiting protrusion 12 and the arc limiting tooth 13, and the integrated magnetizing synchronous reluctance roller motor works normally at this time; when the shaft 100 and the arc groove 200 rotate in the reverse direction, the arc groove 200 contacts (engages) the limiting protrusion 12 and the arc limiting tooth 13, and the integrated magnetizing synchronous reluctance roller motor stops working at this time.
[0024] In addition, the brake device for the integrated magnetic synchronous reluctance drum motor preferably includes a plurality of backstop outer body mounting and positioning holes 10 and a set of backstop outer body positioning holes 11 disposed on one side of the backstop outer body 1, for fixing to the outer cover surface 7 and the outer cover 8 by bolts (not shown in the figure, which does not affect the disclosure of the technical solution of this application).

[0026] In addition, the brake device for the integrated magnetic synchronous reluctance roller motor preferably includes a set of positioning holes 40 for the inner circular body of the slotted backstop 4 located on one side of the inner circular body 4, for fixing to the outer cover 7 and the outer cover 8 by bolts (not shown in the figure, which does not affect the disclosure of the technical solution of this application).
[0027] In addition, the brake device for the integrated magnetic synchronous reluctance drum motor preferably includes an outer elastic retaining ring mounting hole 60 and an inner elastic retaining ring mounting hole 30 respectively provided in the end faces of the outer elastic retaining ring 6 and the inner elastic retaining ring 3, which are respectively sealed and fixed to the outer cover surface 7, the outer cover 8 and the bearing 300 by bolts (not shown in the figure, which does not affect the disclosure of the technical solution of this application).
[0028] The aforementioned braking device is suitable for high-torque, heavy-load applications, such as large hoists and mining equipment, and is used in conjunction with an integrated magnetic synchronous reluctance drum motor.
