Description

Technical Field

[0001] The utility model relates to the field of motor stators, in particular to a motor stator rotating baking roller frame. Background Art

[0002] The insulating varnish of a motor's stator plays a crucial role in preventing short circuits between the motor's internal wires or between the wires and the motor casing. Insulating varnish typically has good thermal conductivity, helping to transfer heat generated within the motor to the outside, thereby lowering the motor's operating temperature. Good insulation reduces energy loss and improves motor efficiency. Therefore, the quality of the insulating varnish directly impacts the motor's service life.

[0003] The current drying method involves placing the varnished stator on a flat car and drying it in a drying room. This drying method results in uneven heating of the stator, a slow curing process, and poor local treatment, which can lead to variations in motor performance, low efficiency, and reduced product quality. Utility Model Content

[0004] The purpose of the utility model is to provide a motor stator rotating baking roller frame, which overcomes the above-mentioned technical defects and provides equipment for drying large stator insulating paint. The explosion-proof motor drives the reduction gearbox to drive the long roller to rotate, so that the motor stator is rotated and baked inside the drying room after being dipped in paint. The rotary baking can make the insulating paint evenly heated and accelerate the curing process of the paint.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present invention provides a motor stator rotating baking roller frame, including a positioning base, a bearing base arranged at both ends of the positioning base, a bearing seat arranged on the bearing base, a long roller with both ends respectively connected to the bearing seat, and an explosion-proof motor arranged on one side of the long roller, and the explosion-proof motor is connected to the end of the long roller through a reduction box and a coupling.

[0006] Preferably, a positioning ring may be provided on the long roller.

[0007] Preferably, a dial is provided between the reduction gearbox and the coupling.

[0008] Preferably, a radial base plate is further provided on the same T-block, and the bearing base, the bearing seat, and the long roller are provided on the radial base plate.

[0009] Preferably, a plurality of auxiliary brackets are provided between the two bearing bases located on the same positioning base plate or the radial base plate.

[0010] Preferably, the positioning base plate is arranged on the T-block, and the reduction gear box is arranged on a reduction gear box bracket.

[0011] Preferably, two slip ring brackets are provided on the reduction box bracket, a connecting rod is connected between the two slip rings, and the slip ring is provided on the connecting rod.

[0012] Preferably, the reduction box bracket, the explosion-proof motor, and the reduction box are all placed outside the drying room, and the T-block is arranged on a drying room flat car.

[0013] In summary, the present invention has the following beneficial technical effects:

[0014] 1. Because the large rotor rotating baking rollers rotate at a constant and slow speed during the drying process, the insulating paint is evenly heated, accelerating the curing of the paint and ensuring a uniform curing effect across the entire stator. This improves the quality stability of the motor product and reduces performance variations caused by poor local processing.

[0015] 2. Low manufacturing cost, wide application range and easy maintenance.

[0016] 3. High processing efficiency: It can improve product quality, make the color of the edge paint uniform and beautiful, make the motor appearance more neat and easy to operate, and increase work efficiency several times, which can meet the needs of different stator processing procedures.

[0017] 4. Small footprint, safe and reliable: The utility model is a detachable device, which occupies a small area and is suitable for limited space resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The present invention discloses a motor stator rotating baking roller frame. The purpose of the present invention is achieved through the following technical solutions:

[0022] The large stator rotating baking roller frame mainly consists of: a long roller 1, a positioning base plate 4, a radial base plate 7, a bearing seat 2, a bearing, a sprocket, a positioning ring 8, a coupling 15, a dial 14, an auxiliary bracket 5, a slip ring bracket 12, a slip ring 11, a T-block 6, an explosion-proof motor 10 (AC 18.5KW), and a reduction box 13 (i=187, i.e., a speed ratio of 187:1).

[0023] The explosion-proof motor 10 and the reduction box 13 are fixed on the reduction box bracket 9 and placed outside the drying room; the T-block 6 is fixed on the drying room flat car; the positioning base plate 4 and the radial base plate 7 are fixed on the T-block 6 with screws.

[0024] The positioning base plate 4 is fixed to the bearing seat 2 and the auxiliary bracket 5 with screws respectively; the long roller 1 is connected to the bearing seat 2 and fixed on the bearing seat 2; the sprocket is fixed to one side of the long roller 1; the auxiliary bracket 5 is fixed to the positioning base plate 4 and the radial base plate 7 respectively as auxiliary support;

[0025] Working Principle: An explosion-proof motor (10) drives a reduction gearbox (13) connected to a long drum (1), causing the drum (1) to rotate, which in turn drives the stator (1) to achieve rotary baking. Positioning rings (8) are located on either side of the drum (1) to prevent the stator from falling out. Different stator sizes result in different opening distances for the rotating baking rollers, which can be achieved by radially moving the base plate (7), thereby meeting process requirements.

[0026] The explosion-proof motor 10 drives the reduction gear 13, which in turn rotates the long drum 1. After the motor stator is dipped in paint, it is then rotated and baked inside the drying chamber. Rotational baking evenly heats the insulating paint, accelerating the paint curing process. The heat from the rotational baking process dissipates any moisture that may have been absorbed by the stator before dipping. Moisture can reduce insulation resistance and affect the motor's electrical performance. Rotational baking ensures the stator remains dry, improving the motor's reliability and service life.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
