As illustrated in
According to the present disclosure, the motor support apparatus is configured as the at least one beam structure. The beam structure is a structure formed by bending two long sides of the rectangular metal plate relative to each other, and the structure formed by the bending is unclosed. Therefore, according to the beam structure of present disclosure, a bent edge may be adjusted depending on different motor axial heights. Therefore, a vertical height of the beam structure could be adjusted according to actual requirements, and an adjustable range of the height of the motor support apparatus is expanded, better satisfying mounting requirements of drive motors of different shaft heights, effectively improving universality of the motor support apparatus. The motor support apparatus is suitable for a plurality of motors having different shaft heights.
The beam structure 1 is a U-shaped beam in a structural form, with a U-shaped cross section of the beam; and/or the beam structure 1 is formed as a semi-closed internal cavity structure 15 by bending, a support plate 2 being provided in the internal cavity structure 15. This is a preferred structural form of the beam structure of the present disclosure. By configuring the beam structure as a U-shaped beam having a U-shaped cross section, a magnitude of the vertical height of the beam structure could be further adjusted through a side of the unclosed spacing to satisfy the motors having different shaft heights; and by setting a structural form in which the support plate is disposed in an internal cavity of the beam structure, the support strength of the beam structure could be further improved.
A bent structure having a plurality of sections connected to each other, is formed along a length direction of the beam structure 1 thereof: or a curved structure is formed along the length direction of the beam structure 1 thereof. In the present disclosure, these are two different preferred structural forms of the beam structure in the length direction. A first preferred structure form is the bent structure having the plurality of sections connected to each other. Such a bent structure is beneficial to form a fastening connection of straight sections at two ends to the motor separately, while a middle section is connected to a bottom of the motor support apparatus, such as a base plate or chassis. Therefore, according to a special configuration of the one beam structure, the connections to different components could be realized at different parts of the beam, which reduces materials and provides a more compact structure while achieving a fixing effect. Similarly, for a beam structure of the curved structure, a fastening connection may be formed between an end section of the beam structure and the motor, while a middle section is connected to the bottom of the motor support apparatus, such as the base plate or the chassis. Therefore, according to the special configuration of the one beam structure, the connections to different components could be realized at different parts of the beam, which reduces materials and provides a more compact structure while achieving the fixing effect.
The bent structure 1 having the plurality of sections connected to each other includes a first straight section 1a, a second straight section 1b, and a third straight section 1c. The second straight section 1b is connected between the first straight section 1a and the third straight section 1c, in such a manner that the first straight section 1a, the second straight section 1b, and the third straight section 1c are sequentially connected. The first straight section 1a and the second straight section 1b form a bend at the junction thereof. The second straight section 1b and the third straight section 1c form a bend at the junction thereof. This is a further preferred structural form of the beam structure of the bent structure having the plurality of sections of the present disclosure, i.e., a fastening connection with the motor may be formed through the first straight section and the third straight section, and a fastening connection between the motor support apparatus and the base plate or the chassis is formed through the second straight section.
The beam structures 1 includes a first beam 13 and a second beam 14. A second straight section of the first beam 13 is connected to a second straight section of the second beam 14. A first section of the first beam 13 extends away with respect to the second beam 14, and a third section of the first beam 13 extends away with respect to the second beam 14. A first section of the second beam 14 extends away with respect to the first beam 13, and a third section of the second beam 14 also extends away with respect to the first beam 13. That is, a motor support in an “X” shape is formed. Compared with the conventional straight beam, the two multi-section bent beam structures, which are arranged and connected to each other back-to-back and extends away with respect to each other, effectively reduce a quantity of the beam structures in use, effectively reduce the materials, reduce the costs, improve economical efficiency of products, and save space of the whole machine, while satisfying the condition of being permanently connected to the motor at four different positions.
The X-shaped motor support of the present disclosure is preferentially applied in a single-stage centrifugal blower. There is only one size of the compressor element, while there are five shaft heights of the drive motor used in total. A motor mounting manner is a mounting manner with four bottom feet and a flange. For a motor with a same mounting size, the X-shaped motor support requires fewer materials than the rectangular support, which reduces the costs, improves the economical efficiency of products, and saves the space of the whole machine.
The first beam 13 and the second beam 14 have a same structure and a same shape and they are connected to each other symmetrically; and/or the second straight section of the first beam 13 is permanently connected to the second straight section of the second beam 14. Preferably, screw, welding, or bonding, etc. is used for the connection. It is a further preferred structural form of the first beam and the second beam of the present disclosure, i.e., structures and shapes of the first beam and the second beam are set to be the same, which could provide a uniform support for the motor from four directions to prevent tilting of the motor. The fixed connection of two straight sections of the first beam and the second beam could enable the first beam and the second beam to be fixed into one piece through the middle sections, and the stability of the motor support apparatus is improved. It provides an effective and stable support when it is arranged at a bottom of the motor.
A first reinforcing rib 31 is provided at the junction of the first straight section 1a and the second straight section 1b, and a shape of the first reinforcing rib 31 matches a shape of the bend at the junction of the first straight section 1a and the second straight section 1b; and/or a second reinforcing rib 32 is provided at a junction of the second straight section 1b and the third straight section 1c, and a shape of the second reinforcing rib 32 matches a shape of the bend at the junction of the second straight section 1b and the third straight section 1c. By providing the first reinforcing rib, a reinforcing and strengthening effect could be achieved at the junction of the first straight section and the second straight section, which could further effectively improve the structural strength of the motor support apparatus. By providing the second reinforcing rib, a reinforcing and strengthening effect could be achieved at the junction of the second straight section and the third straight section, which could further effectively improve the structural strength of the motor support apparatus.
The first reinforcing rib 31 is arranged on a side of an opening of the unclosed shape of the beam structure 1, and has one end permanently connected to the first free end side 11 and another end permanently connected to the second free end side 12; and/or the second reinforcing rib 32 is arranged on a side of the opening of the unclosed shape of the beam structure 1, and has one end permanently connected to the first free end side 11 and another end permanently connected to the second free end side 12. Since the beam structure defines the opening of the unclosed shape on one side, a structural strength at that position may have a serious risk, and phenomena such as deformation or damage, etc. may occur under a pressure. Therefore, with the first reinforcing rib arranged at the opening position, connecting and fastening the upper and lower end sides, the structural strength of the opening and the bending part could be effectively enhanced. With the second reinforcing rib arranged at the opening position, connecting and fastening the upper and lower end sides, the structural strength of the opening and the bending part could also be effectively enhanced.
As illustrated in
The X-shaped motor support of the present disclosure is preferentially applied in the single-stage centrifugal blower. There is only one size of the compressor element of the product, and there are five shaft heights of the drive motor used in total. The motor mounting manner is a mounting manner with four bottom feet and a flange. A bracket of the X-shaped motor support of the present disclosure is composed of two main U-shaped beams. Each U-shaped beam is manufactured by performing a simple bending operation on a metal plate. Some reinforcing ribs/support plates are welded on the U-shaped beam to ensure strength and rigidity of the support structure for motor. Since an adjustable range of the U-shaped beam's height is wide, the mounting requirements of the drive motors having different shaft heights could be more easily satisfied. For the motor with the same mounting size, the X-shaped motor support requires fewer materials than the rectangular support, which reduces the costs, improves the economical efficiency of products, and saves the space of the whole machine.

Each U-shaped beam is manufactured by performing a simple bending operation on a metal plate. In addition, some reinforcing ribs/support plates are welded on the U-shaped beam to ensure the strength and rigidity of the support structure for motor.
Advantages of the present disclosure as followings:
