Description

Technical Field

[0001] This application relates to the field of permanent magnet high-speed motor installation technology, and specifically discloses an adjustable mounting support structure for a permanent magnet high-speed motor based on a reduced frame size. Background Technology

[0002] High-efficiency rare-earth permanent magnet synchronous motors are a type of permanent magnet high-speed motor. As a representative of high-efficiency and energy-saving motors, high-efficiency rare-earth permanent magnet synchronous motors have an extremely wide range of applications, covering almost all fields of aerospace, national defense, industrial and agricultural production, and daily life.

[0003] With the increasing demand for high-efficiency rare-earth permanent magnet synchronous motors in the industrial sector, in order to reduce retrofit costs, improve retrofit efficiency, and meet the requirement of not changing the original installation foundation, the design of high-efficiency rare-earth permanent magnet synchronous motors often requires the use of a national standard asynchronous motor frame with the same center height and mounting hole dimensions as the original motor. However, this design sacrifices the advantages of high-efficiency rare-earth permanent magnet synchronous motors under the same power conditions, such as small size, light weight, and less copper and iron usage, increasing the cost of high-efficiency rare-earth permanent magnet synchronous motors and hindering their promotion and development. High-efficiency rare-earth permanent magnet synchronous motors with reduced frame size can leverage their advantages of small size, light weight, and low copper and iron consumption. However, retrofitting high-efficiency rare-earth permanent magnet synchronous motors with reduced frame size presents challenges such as incompatibility between the retrofitted installation and the original motor frame foundation, and inconsistent center height. This results in the inability to fully utilize the advantages of high-efficiency rare-earth permanent magnet synchronous motors without altering the original motor mounting foundation, leading to higher production and retrofitting costs. In view of this, this utility model provides an adjustable mounting support structure for a high-speed permanent magnet motor with reduced frame size to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem of high production and modification costs caused by the mismatch between the modified installation and the original motor frame foundation and the inconsistent center height in the modification of traditional high-efficiency rare-earth permanent magnet synchronous motors with reduced frame size.

[0005] To achieve the above objectives, the basic solution of this utility model provides an adjustable mounting support structure for a permanent magnet high-speed motor based on a reduced frame size, comprising: The base plate has a plurality of mounting holes symmetrically provided for mounting movable motors; A support column is vertically slidably connected to the base plate, and the side wall of the support column has several adjustment holes evenly distributed vertically. An adjusting block is detachably connected to the adjusting hole of the support column and detachably connected to the base plate.

[0006] The principle and effect of this basic scheme are as follows: Compared with existing technologies, this utility model, by setting a base plate, a support column, and an adjusting block, and by using the adjusting block and the base plate to connect with each other, and by utilizing the adjusting holes at different height positions of the adjusting block and the support column, can adjust the distance between the base plate and the bottom of the support column. This achieves the purpose of adjusting the center height in the modification of high-efficiency rare-earth permanent magnet synchronous motors with reduced frame size. It effectively solves the problem of high production and modification costs caused by the incompatibility between the modification and installation and the original motor frame foundation and the inconsistent center height in the traditional modification of high-efficiency rare-earth permanent magnet synchronous motors with reduced frame size.

[0007] Furthermore, the side wall of the base plate is provided with a through groove that allows the support column to slide vertically, and the base plate is provided with connecting holes on both sides of the through groove. The adjusting block is detachably connected to the connecting holes. This facilitates the cooperation between the support column and the base plate, and allows the adjusting block to fix or detach the support plate from the base plate.

[0008] Furthermore, the sidewalls of the adjusting block are respectively provided with a plurality of lateral mating holes that mate with the adjusting hole and a plurality of vertical mating holes that communicate with the connecting hole. The sidewalls of the adjusting block are provided with a plurality of first fasteners that extend into the lateral mating holes and the adjusting holes, and the surface of the base plate is provided with a plurality of second fasteners that extend into the connecting hole and the vertical mating holes. This facilitates the use of the adjusting block to fix or disassemble the support plate and the base plate.

[0009] Furthermore, the adjustment block includes: The fixed base is detachably connected to the support column; A sliding seat is detachably connected to the base plate and vertically slidably connected to the fixed seat; An adjustment component is disposed between the fixed base and the sliding base and is used to adjust the vertical height of the sliding base.

[0010] This makes the overall height of the adjustment block adjustable, meaning the distance between the adjustment hole and the base plate can be further fine-tuned, which in turn allows for further adjustment of the center height during the modification of the high-efficiency rare-earth permanent magnet synchronous motor, increasing the adjustment range and versatility of the installation support structure.

[0011] Furthermore, the top surface of the fixed base is provided with a receiving groove, the bottom of the sliding base extends into the receiving groove and is vertically slidably connected to the side wall of the receiving groove, and the top of the sliding base extends out of the receiving groove and is detachably connected to the base plate. This serves to limit and guide the sliding of the sliding base.

[0012] Furthermore, the adjustment component includes: The first wedge is located at the bottom of the sliding seat; The adjusting screw is threadedly connected to the side wall of the receiving groove; The second wedge is slidably connected in the receiving groove and rotatably connected to the end of the adjusting screw, and the inclined surfaces of the first wedge and the second wedge are adapted to each other.

[0013] The position of the sliding seat can be adjusted by the cooperation of the first and second wedges.

[0014] Furthermore, the end of the adjusting screw extends out of the side wall of the receiving groove and is equipped with a knob. This allows the adjusting screw to be rotated, thereby moving the second wedge block.

[0015] Furthermore, the side wall of the receiving groove is also provided with a threaded seat that is threadedly connected to the adjusting screw. The threaded seat improves the threaded fit performance between the fixed seat and the adjusting screw.

[0016] Furthermore, the bottom of the receiving groove is provided with several guide strips, and the bottom of the second wedge is provided with a guide groove that matches the guide groove. This serves to limit and guide the sliding of the second wedge.

[0017] Furthermore, one end of the adjusting screw extends into the second wedge and is provided with an anti-disengagement retaining ring rotatably connected inside the second wedge to prevent the adjusting screw from disengaging from the second wedge. Attached Figure Description
