Description

Technical Field

[0001] The invention relates to the technical field of air preheaters, and in particular to a power source installation structure and an air preheater reducer. Background Art

[0002] The air preheater reducer is a multi-axis horizontal input and vertical single-axis output reducer. The purpose of setting the multi-axis input is to be able to start the auxiliary input motor in a chain manner when the main input motor burns out, to ensure that the air preheater reducer can switch the motor to ensure that the air preheater reducer runs without stopping, thereby improving the operating safety performance of the air preheater reducer.

[0003] The auxiliary input shaft and the auxiliary motor are generally connected by a wedge-type clutch. When the air preheater reducer is running, the auxiliary motor is disconnected and the auxiliary motor does not rotate, thereby protecting the auxiliary motor from wear and tear, and reducing the influence of the induced potential and harmonic waves introduced by the auxiliary motor's rotation. However, since the mechanical wear of the wedge-type clutch cannot be avoided during long-term disengagement, the wedge-type clutch is frequently damaged, is a vulnerable part, and is difficult to replace. It needs to stop the preheater reducer before replacement. This setting actually reduces the operating safety performance of the air preheater reducer. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, an embodiment of the present invention provides a power source installation structure, which has the advantages of high efficiency in motor maintenance and replacement.

[0006] An embodiment of the present invention further provides an air preheater reducer.

[0007] The power source mounting structure of the embodiment of the present invention is used to be installed on an output device, and includes a first flange, a second flange, a motor, an inner magnetic ring, an outer magnetic ring and a base, wherein the first flange is installed outside the housing of the output device, one of the first flange and the second flange is provided with a positioning hole, the axial direction of the positioning hole is consistent with the axial direction of the input shaft of the output device, and the other of the first flange and the second flange can be slidably fitted in the positioning hole; the motor includes a connecting bracket, the connecting bracket is connected to the second flange, and the axial direction of the rotating shaft of the motor is consistent with the axial direction of the positioning hole; one of the inner magnetic ring and the outer magnetic ring is coaxially connected to the input shaft of the output device, and the other is coaxially connected to the rotating shaft; the base is connected to the housing, and the second flange is slidably connected to the base along the axial direction of the rotating shaft.

[0008] According to the power source installation structure of the embodiment of the present invention, after the base is connected to the housing of the output device, the second flange is set to slide axially along the input shaft of the output device relative to the base, so as to facilitate the second flange and the motor installed thereon to move closer to and away from the output device, so as to achieve the matching of the magnetic inner ring and the magnetic outer ring. Among them, after the magnetic inner ring is matched with the magnetic inner ring, the first flange and the second flange are plugged and matched through the positioning hole, thereby ensuring the centering positioning of the magnetic inner ring and the magnetic outer ring, and ensuring the reliable connection between the rotating shaft of the motor and the input shaft in the output device. By only fixing the motor on the second flange through the connecting bracket, when the motor needs to be maintained or replaced, it is only necessary to move the second flange to separate the magnetic inner ring and the magnetic outer ring, and then remove the motor from the second flange. Under the support of the base, the position of the second flange remains unchanged when the motor is removed, and then after the motor is installed, maintained or replaced, it is no longer necessary to readjust the first flange and the second flange. The positioning is effectively improved, thereby effectively improving the maintenance and replacement efficiency of the motor, and also ensuring the operation safety performance of the output device.

When the magnetic inner ring is located at the first position, part of the first flange is engaged in the positioning hole, and the limiting flange abuts against the end face of the shell of the output device facing the second flange.

[0022] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0023] Combine the following Figure 1 A power source mounting structure and an air preheater reducer according to an embodiment of the present invention are described.

[0024] The power source installation structure of the embodiment of the present invention is used to be installed on the output device, and includes a first flange 3, a second flange 4, a motor 2, a magnetic inner ring 5, a magnetic outer ring 6 and a base 7. The first flange 3 is installed outside the housing 11 of the output device, and one of the first flange 3 and the second flange 4 is provided with a positioning hole, the axial direction of the positioning hole is consistent with the axial direction of the input shaft 12 of the output device, and the other of the first flange 3 and the second flange 4 can be slidably fitted in the positioning hole. The motor 2 includes a connecting bracket 21, the connecting bracket 21 is connected to the second flange 4, and the axial direction of the rotating shaft of the motor 2 is consistent with the axial direction of the positioning hole. One of the magnetic inner ring 5 and the magnetic outer ring 6 is coaxially connected to the input shaft 12 of the output device, and the other is coaxially connected to the rotating shaft. The base 7 is connected to the housing 11, and the second flange 4 is slidably connected to the base 7 along the axial direction of the rotating shaft.

[0025] According to the power source installation structure of the embodiment of the present invention, after the base 7 is connected to the housing 11 of the output device, the second flange 4 is set to slide axially relative to the base 7 along the input shaft 12 of the output device, so as to facilitate driving the second flange 4 and the motor 2 mounted thereon to approach and move away from the output device, so as to achieve the matching of the magnetic inner ring 5 and the magnetic outer ring 6. Among them, after the magnetic inner ring 5 is matched with the magnetic inner ring 5, the first flange 3 and the second flange 4 are plugged and matched through the positioning holes, thereby ensuring the centering positioning of the magnetic inner ring 5 and the magnetic outer ring 6, and ensuring the reliable connection between the rotating shaft of the motor 2 and the input shaft 12 in the output device. By only fixing the motor 2 on the second flange 4 through the connecting bracket 21, when the motor 2 needs to be maintained or replaced, it is only necessary to move the second flange 4 to separate the inner magnetic ring 5 and the outer magnetic ring 6, and then remove the motor 2 from the second flange 4. With the support of the base 7, the position of the second flange 4 remains unchanged when the motor 2 is removed, and then after installing the motor 2 after maintenance or replacement, there is no need to readjust the first flange 3 and the second flange 4, thereby effectively improving the maintenance and replacement efficiency of the motor 2 and ensuring the operating safety performance of the output device.

[0026] It should be noted that the output device may be a reducer 1 , which includes a plurality of input shafts 12 , wherein one or more input shafts 12 are connected to the rotating shaft of the motor 2 through the cooperation of the magnetic inner ring 5 and the magnetic outer ring 6 mentioned above.

[0027] In some embodiments, Figure 1 As shown, a sliding mechanism 8 is installed on the base 7 , and the sliding mechanism 8 includes a sliding block 81 . The sliding block 81 is slidably connected to the base 7 along the axial direction of the rotating shaft, and the sliding block 81 is connected to the second flange 4 .

[0028] On the basis of the sliding fit between the slider 81 and the base 7 , the slider 81 is connected to the second flange 4 so that the base 7 supports the second flange 4 through the slider 81 , thereby ensuring the positioning reliability of the second flange 4 and the first flange 3 .

[0029] Specifically, the slider 81 is in a rectangular parallelepiped shape, and a guide groove may be provided on the upper surface of the base 7, and the slider 81 is slidably fitted in the guide groove.

[0030] In some embodiments, the sliding mechanism 8 also includes a screw rod 82, which is rotatably installed on the base 7 around its axis. The axial direction of the screw rod 82 is consistent with the axial direction of the rotating shaft. A threaded hole is provided on the slider 81, and the threaded hole is threadedly matched with the external thread of the screw rod 82.

[0031] By rotating the screw 82, the internal thread on the slider 81 and the external nut of the screw 82 rotate relative to each other, thereby realizing the sliding fit of the slider 81 on the base 7, thereby realizing the insertion and removal of the magnetic inner ring 5 from the magnetic outer ring 6, and after the motor 2 and the second flange 4 move to the set position relative to the first flange 3, the motor 2 and the second flange 4 are less likely to move accidentally, thereby effectively preventing the magnetic inner ring 5 from being accidentally inserted into the magnetic outer ring 6 or accidentally removed from the magnetic outer ring 6 to affect the operating state of the air preheater reducer.

[0032] Two baffles are arranged above the base 7 and are spaced apart from each other along the axial direction of the rotating shaft. Both ends of the screw rod 82 are pivotally mounted on the two baffles through bearings.

[0033] In some embodiments, the power source mounting structure further includes a handle 83 , which is connected to one end of the screw rod 82 .

[0034] That is, the staff can manually control the rotation of the screw rod 82 through the handle 83 to realize the movement of the motor 2, thereby effectively reducing the manufacturing cost of the power source installation structure.

[0035] Specifically, the handle 83 includes a first rod segment extending radially of the screw rod 82 and a second rod segment extending axially of the screw rod 82 . The first end of the first rod segment is connected to the screw rod 82 , and the second end of the first rod segment is connected to the second rod segment.

[0036] In some embodiments, Figure 1 As shown, the magnetic inner ring 5 has a first position fitted in the magnetic outer ring 6 and a second position separated from the magnetic outer ring 6, the positioning hole is arranged on the second flange 4, and the outer peripheral surface of the first flange 3 is provided with a limiting flange 31. When the magnetic inner ring 5 is located in the first position, part of the first flange 3 is fitted in the positioning hole, and the limiting flange 31 abuts against the end face of the second flange 4 facing the housing 11 of the output device.

[0037] The setting of the limiting flange 31 ensures that the inner magnetic ring 5 moves to the first position after the second flange 4 abuts against the limiting flange 31, that is, the reliable connection between the motor 2 shaft and the input shaft 12 of the output device is completed, and the connection between the two is fast and reliable.

[0038] Specifically, the positioning hole is a circular hole, and the limiting flange 31 extends along the circumference of the first flange 3 and is connected end to end.

[0039] It should be noted that the positioning holes may also be provided on the first flange 3 .

[0040] In some embodiments, when the inner magnetic ring 5 is located at the second position, a portion of the first flange 3 is slidably fitted in the positioning hole.

[0041] That is, when replacing the motor 2, the first flange 3 and the second flange 4 are still in a positioned and matched state. Therefore, after the maintained or replaced motor 2 is connected to the second flange 4, there is no need to match and position the first flange 3 and the second flange 4, and the maintenance and replacement efficiency of the motor 2 is higher.

[0042] Specifically, the second flange 4 is coaxial with the shaft, and the second flange 4 is connected to the connecting bracket 21 through a plurality of screws, and the plurality of screws are arranged at intervals along the circumference of the shaft. The screws may be bolts or a combination of bolts and nuts.

[0043] In some embodiments, the positioning hole is coaxial with the rotating shaft, the first flange 3 forms a mounting cavity with an opening toward the motor 2 , and the magnetic outer ring 6 is located in the mounting cavity.

[0044] That is, the first flange 3 includes a magnetic outer ring 6, so that when the first flange 3 and the second flange 4 cooperate with each other, the first flange 3 and the second flange 4 separate the magnetic outer ring 6 and the magnetic inner ring 5 from the outside world, thereby effectively preventing external dust and other impurities from adhering to the magnetic outer ring 6 and the magnetic inner ring 5 and affecting the connection reliability between the two.

[0045] In some embodiments, the first flange 3 is provided with a plurality of positioning holes, which are arranged at intervals along the circumference of the magnetic inner ring 5, and the second flange 4 is provided with a plurality of positioning columns, which correspond to the positioning holes one by one and fit into the positioning holes.

[0046] That is, the alignment of the inner magnetic ring 5 and the outer magnetic ring 6 can be achieved by setting a plurality of positioning holes and cooperating with corresponding positioning columns. At this time, the second flange 4 also includes a base plate, all the positioning columns are connected to the base plate, and the base plate is used to connect with the slider 81 and the connecting bracket 21 of the motor 2.
