Description

Technical Field

[0001] This utility model relates to motor technology, and more specifically, to motor housing. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It is widely used in industrial production, transportation, and household appliances. Electric motors are based on electromagnetic induction and generate torque through the interaction of magnetic fields between the stator and rotor, thus driving the equipment to operate.

[0003] The housing, as the outermost part of the motor, is used to protect the internal structure of the motor. Existing housings are generally equipped with lifting rings for easy hoisting of the motor during installation. The housing is integrally formed with reinforcing ribs, and the lifting rings are usually placed on the reinforcing ribs.

[0004] Most existing lifting rings are threaded onto reinforcing ribs, and their positions are fixed and cannot be changed. The installation position of the lifting ring is usually set along the plumb line of the motor. This setting can maintain the balance of the motor when lifting it alone. However, in some special assembly situations, such as the installation of tunnel fans with the fan blades inside and the motor outside, it is necessary to install the fan blades and other devices on the motor first. This will cause the center of gravity of the motor to shift, resulting in a large tilt when lifting the motor. This may cause unnecessary trouble for the subsequent installation of the motor.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a motor housing.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a motor housing, including a housing body, a reinforcing rib on the top surface of the housing body, a sliding groove on the reinforcing rib, a slider slidably connected in the sliding groove, a lifting ring threadedly connected to the slider, and an adjusting component on the reinforcing rib for adjusting the position of the slider in the sliding groove.

[0008] The present invention is further configured such that: the adjusting member includes a threaded section rotatably connected to two opposite side walls of the slide groove, and the slider has a through hole that is threadedly engaged with the threaded section.

[0009] The present invention is further configured such that: the lifting ring has an opening concentric with the through hole, and the inner diameter of the opening is equal to the major diameter of the threaded section.

[0010] The present invention is further configured such that: the adjusting member includes a first circular segment and a second circular segment respectively rotatably connected to the two opposite side walls of the reinforcing rib, and the two ends of the threaded segment are respectively fixedly connected to the first circular segment and the second circular segment.

[0011] The present invention is further configured such that: the diameter of the first circular segment is equal to the major diameter of the threaded segment, the minor diameter of the threaded segment is greater than the diameter of the second circular segment, and the first circular segment has a hexagonal head that abuts against the reinforcing rib on the side away from the threaded segment.

[0012] The present invention is further configured such that: an annular groove is provided on the outer peripheral wall of the second circular segment, and a retaining spring for contacting the reinforcing rib is detachably provided in the annular groove.

[0013] In summary, this utility model has the following beneficial effects: When installing other devices onto the motor, the motor's center of gravity shifts. When using lifting rings to hoist the motor, it tilts. At this time, the operator uses the adjusting mechanism to make the slider slide along the inner wall of the groove towards the plumb line, so that the lifting ring moves synchronously with the slider, reducing the degree of motor tilt and keeping the motor in a balanced state as much as possible, which facilitates the subsequent installation of the motor.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Motor housing, such as Figure 1 and Figure 2As shown, the device includes a housing body 1. The top surface of the housing body 1 is integrally formed with a reinforcing rib 2. A groove 3 is provided on the reinforcing rib 2. A slider 4 with an inverted T-shaped cross-section is slidably connected in the groove 3. A lifting ring 5 is threadedly connected to the slider 4. The reinforcing rib 2 is provided with an adjusting component for adjusting the position of the slider 4 in the groove 3. When other devices are installed on the motor, the center of gravity of the motor shifts. When the motor is lifted using the lifting ring 5, the motor tilts. At this time, the operator operates the adjusting component to make the slider 4 slide along the inner wall of the groove 3 toward the plumb line, so that the lifting ring 5 moves synchronously with the slider 4, reducing the degree of tilt of the motor and keeping the motor in a balanced state as much as possible, which facilitates the subsequent installation of the motor.

[0018] like Figure 2 and Figure 4 As shown, the adjusting component includes a threaded section 6 rotatably connected to two opposite side walls of the slide groove 3. The slider 4 has a through hole 7 that threadedly engages with the threaded section 6. When the position of the lifting ring 5 needs adjustment, the operator rotates the adjusting component to cause the threaded section 6 and the slider 4 to rotate relative to each other, allowing the slider 4 to slide along the inner wall of the slide groove 3, thereby adjusting the position of the lifting ring 5. Because threaded adjustment has the advantage of smoothness, this design makes the position adjustment of the slider 4 relatively smooth, making it possible to adjust while lifting. This allows the operator to precisely control the movement of the lifting ring 5. Furthermore, threaded adjustment also has the advantage of good self-locking. After the relative position of the lifting ring 5 is adjusted, the threaded section 6 is less likely to rotate relative to the slider 4, thus better maintaining the balance of the motor after the device is installed. The lifting ring 5 has an opening 8 concentric with the through hole 7. The inner diameter of the opening 8 is equal to the major diameter of the threaded section 6. Specifically, the lifting ring 5 is first threadedly installed on the slider 4. Then, a hole is drilled and tapped on the side wall of the slider 4 so that a threaded hole is formed on the lifting ring 5 at the same time. After the lifting ring 5 is removed from the slider 4, the threads in the threaded hole of the lifting ring 5 are milled flat. When the motor is lifted, the outer peripheral wall of the threads on the threaded section 6 abuts against the inner peripheral wall of the opening 8, so that the threaded section 6 can also share the weight of the motor at the same time, further ensuring the stability of the motor lifting.

[0019] like Figures 2 to 4As shown, the adjusting component includes a first circular segment 9 and a second circular segment 10 rotatably connected to the two opposite side walls of the reinforcing rib 2. The two ends of the threaded segment 6 are fixedly connected to the first circular segment 9 and the second circular segment 10, respectively. The diameter of the first circular segment 9 is equal to the major diameter of the threaded segment 6, and the minor diameter of the threaded segment 6 is greater than the diameter of the second circular segment 10. A hexagonal head 11, which abuts against the reinforcing rib 2, is provided on the side of the first circular segment 9 away from the threaded segment 6. Specifically, the adjusting component is machined from the same hexagonal bar stock, and the hexagonal head 11 is formed by precision milling of the hexagonal bar stock. The precision-milled hexagonal head 11 is clamped and machined on a lathe to form the first circular segment 9 and the second circular segment 10. Then, the threaded segment 6 is machined on the outer peripheral wall of the second circular segment 10, completing the machining of the adjusting component. This configuration ensures the overall integrity of the adjusting component. The strength and the hexagonal head 11 allow operators to rotate the adjusting component using tools such as wrenches, facilitating the adjustment of the lifting ring 5 position. When rotating the adjusting component, the first circular segment 9 and the second circular segment 10 are both rotatably connected to the side wall of the reinforcing rib 2, making the rotation of the adjusting component relatively smooth, thus ensuring the stability of the motor hoisting to a certain extent. The outer peripheral wall of the second circular segment 10 is provided with an annular groove 12, in which a retaining spring 13 for contacting the reinforcing rib 2 can be detached. The retaining spring 13, while reducing the impact on the rotation of the adjusting component, can also prevent the second circular segment 10 from moving relative to the reinforcing rib 2 in the axial direction, thereby preventing the adjusting component from accidentally separating from the reinforcing rib 2.
