Description

Technical Field

[0001] The utility model relates to an inner liner for stator packaging, in particular to an inner liner for vertically packaging a motor stator with an anti-warping sheet and an anti-scratch rolling bearing. Background Art

[0002] When transporting, the motor stator needs to be loaded in a packaging structure that can effectively contain, position and protect it to avoid damage during transportation.

[0003] For a motor stator with a fixed portion protruding from the annular portion on the edge, the lining used in the stator packaging box in the prior art generally directly adopts an integrally molded structure. When the motor stator is installed into and removed from the lining, the stator itself including the fixed portion is subject to sliding friction with the lining, which is prone to warping and the like, leading to damage. Utility Model Content

[0004] The utility model provides a liner for stator packaging with a rolling bearing, which aims to overcome the above-mentioned shortcomings of the prior art and reduce the possibility of damage when the stator contacts the inner side.

[0005] The technical solution of this utility model is a stator liner for packaging with rolling bearings. Its structure includes an integrally formed polyurethane liner body, which includes an annular portion, a stepped surface, and a mounting plate. The stepped surface, which is used to accommodate the motor stator fixing portion, is located at the edge of the annular portion. Mounting plates are provided on both sides of the stepped surface. A rubber-coated bearing is rotatably mounted at the center of each mounting plate via locking bolts and nuts. When the motor stator is placed inside, the stator fixing portion contacts the rubber-coated bearing, changing the sliding friction of the prior art to rolling friction, which can prevent warping and reduce the risk of damage. Similarly, when the motor stator is removed, the stator fixing portion also contacts the rubber-coated bearing.

[0006] The annular portion also features an integrally formed fixing mushroom head and mounting slot. The fixing mushroom head is located at the bottom of the stepped surface, while the mounting slot is located outside the annular portion. Mounting screw holes are provided at the bottom of the mounting slot. The liner is secured by securing the fixing mushroom head to the desired position within the stator packaging box and then tightening the screws through the mounting screw holes in the mounting slot.

[0007] The advantages of the utility model are as follows: the structural design is reasonable, a rotatable rubber-coated bearing is provided for contacting the fixed part of the stator edge, and rolling friction is achieved when inserting or removing the stator. Compared with the sliding friction in the prior art, the warping of the stator can be reduced, and the risk of damage is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 The utility model is a schematic diagram of the main structure of the inner liner for packaging a stator with a rolling bearing.

[0009] Figure 2 It is a schematic diagram of the three-dimensional structure of an inner liner for packaging a stator with a rolling bearing according to the present invention.

[0010] In the figure, 1 is the annular part, 2 is the step surface, 3 is the mounting plate, 4 is the anti-loosening bolt and nut, 5 is the rubber-coated bearing, 6 is the fixed mushroom head, 7 is the mounting groove, and 8 is the mounting screw hole. DETAILED DESCRIPTION

[0011] The present invention will be further described in detail below with reference to the embodiments and specific implementation methods.

[0012] like Figure 1 、 2 As shown, the liner for stator packaging with rolling bearings has a structure including an integrally molded polyurethane liner body, which includes an annular portion 1, a step surface 2, a mounting plate 3, a fixed mushroom head 6 and a mounting groove 7. The step surface 2 for accommodating the fixed part of the motor stator is arranged at the edge of the annular portion 1, and mounting plates 3 are provided on both sides of the step surface. A rubber-coated bearing 5 is rotatably installed at the center of each mounting plate 3 through an anti-loosening bolt nut 4. A fixed mushroom head 6 is provided at the bottom of the step surface 2, and a mounting groove 7 is provided on the outer side of the annular portion 1. A mounting screw hole 8 is provided at the bottom of the mounting groove 7.

[0013] According to the above structure, when in use, it is fixed in the desired position in the stator packaging box by fixing the mushroom head 6, and reinforced by the mounting screw hole 8 of the mounting groove 7 with screws, and then the motor stator is placed in each inner side. When the stator fixing part is placed, it contacts the rubber-coated bearing 5, and the sliding friction of the prior art is changed to rolling friction, which can avoid the occurrence of warping and reduce the risk of damage. Similarly, when the motor stator is taken out, the stator fixing part also contacts the rubber-coated bearing 5.

[0014] The components described above are all prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0015] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
