Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a motor housing component and a motor. Background Art

[0002] Generally, motors are directly installed at a predetermined position by bolts and other fixings, but for motors used in harsh environments, such as outdoors or on the water, the motor body is generally placed in a housing, and the motor body is protected by the housing to reduce the damage caused by water vapor to the motor. For example, a Chinese invention patent application with publication number CN114513080A discloses an explosion-proof motor protective housing, including a protective housing, an explosion-proof motor body is arranged in the protective housing, an inner frame is fixedly installed inside the protective housing, an extrusion device is arranged inside the inner frame, a shielding device is arranged on the outer wall of the inner frame, a dust removal device is arranged inside the inner frame, a fan is fixedly installed inside the protective housing, and a filter, an extrusion device and a shielding device are arranged on the protective housing. For another example, a Chinese invention patent application with publication number CN110994860A discloses a protective shell for preventing the motor housing from being charged, including a protective shell and a protective cavity inside the protective shell, a motor is arranged on the bottom wall of the protective cavity, a motor is rotatably arranged on the right end face of the motor, a first circular through hole is penetrated on the right end face of the protective shell and is located on the right side of the motor shaft, and the motor shaft extends to the right side of the protective shell through the first circular through hole.

[0003] During actual use, after the motor housing is installed in the predetermined position of the mounting seat, there is often a slight angular deviation between the axis of the motor body output shaft and the axis of the transmission device, which causes greater vibration when the motor is running and accelerates the loss of the motor. In order to alleviate this situation, the installer will add gaskets between the motor housing and the mounting seat before installation to adjust the angle between the motor housing and the motor body. The actual effect of this method is limited, and the gasket may fall off during long-term use, resulting in a clearance between the motor housing and the mounting seat, which will in turn aggravate the vibration during motor operation. Based on this, how to reduce the angular deviation between the axis of the motor body output shaft and the axis of the transmission device, and how to ensure that the axis of the motor body output shaft does not deviate during long-term use, is a problem that technicians in this field need to solve.

In the first state, the lower surface of the lifting plate is in contact with the bottom surface of the groove; in the second state, the upper surface of the lifting plate is flush with the upper surface of the push-pull plate.

[0010] As a preferred technical solution of the present invention, a lifting assembly for lifting the lifting plate is installed on the shell, and the lifting assembly includes a lifting platform slidably installed on the shell in a direction perpendicular to the lifting plate, and upward protrusions are formed on both sides of the lifting platform, and the positions of the protrusions correspond one by one to the grooves; round rods are rotatably installed on both side walls of the lifting platform, and guide rails cooperating with the round rods are slidably installed on the bottom surface of the shell.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, this embodiment provides a motor housing assembly, including a base 1 and a shell 2 rotatably matched with the base 1, the axis of rotation of the shell 2 is a horizontal line, the base 1 is installed at a predetermined position by fasteners such as bolts; the motor body is installed in the shell 2, one end of the shell 2 is closed and the other end is open; a telescopic arm 3 is rotatably installed on the base 1, and one end of the telescopic arm 3 is hinged to the bottom surface of the shell 2. Specifically, as Figure 3 As shown, the telescopic arm 3 includes a guide section 301 rotatably matched with the base 1 and a telescopic section 302 rotatably matched with the shell 2, a cavity 303 is provided inside the telescopic section 302, a through groove 304 communicating with the inside of the guide section 301 is provided at one end of the cavity 303, and a vent 305 is provided at the other end of the cavity 303; a threaded rod 306 is installed on the telescopic section 302 through threaded matching, and a sealing plug 307 matching with the through groove 304 is installed at one end of the threaded rod 306; hydraulic oil is stored in the guide section 301 and the cavity 303, the portion of the sealing plug 307 in contact with the through groove 304 is conical, and the end of the sealing plug 307 facing the inner side of the guide section 301 is the small end.

[0029] During the installation process, the operator first installs the base 1, then places the motor body in the shell 2, and then adjusts the angle of the shell 2 so that the axis of the output shaft of the motor body is aligned with the axis of the external transmission device. During this process, the sealing plug 307 is not in contact with the through groove 304, and the through groove 304 is in an open state. The hydraulic oil in the guide section 301 and the hydraulic oil in the cavity 303 are exchanged through the through groove 304, and the air in the cavity 303 is exchanged with the external air through the vent 305. When the operator has adjusted the angle of the shell 2, he only needs to turn the screw The threaded rod 306 drives the sealing plug 307 to move toward the through groove 304 in a rotating state until the sealing plug 307 fits the through groove 304. At this time, the through groove 304 is closed, and the hydraulic oil in the guide section 301 and the hydraulic oil in the cavity 303 are no longer exchanged, that is, the volume of the hydraulic oil in the guide section 301 remains unchanged. Since the inside of the guide section 301 is in a closed state and the hydraulic oil inside is extremely difficult to be compressed, it is difficult for the telescopic section 302 to move relative to the guide section 301 under the action of external force, that is, the total length of the telescopic arm 3 remains constant. In this way, the angle of the housing 2 can be accurately adjusted to greatly reduce the angle deviation between the axis of the motor body output shaft and the axis of the external transmission device, and the angle of the housing 2 will not change during use, and the use state is very stable.

[0030] like Figure 4 , Figure 5 and Figure 6 As shown, a push-pull plate 4 is slidably installed on the bottom surface inside the shell 2, and two grooves 201 are provided on the bottom surface inside the shell 2, and the grooves 201 are adapted to the shape and size of the supporting feet of the motor body; a notch adapted to the shape and size of the groove 201 is provided at the position corresponding to each groove 201 on the push-pull plate 4; a lifting plate 5 adapted to the shape and size of the groove 201 is also provided in the shell 2; the thickness of the push-pull plate 4 and the lifting plate 5 are consistent; the number of lifting plates 5 is two and they correspond one-to-one to the position of the groove 201, and the lifting plate 5 has a first state and a second state, in the first state, the lower surface of the lifting plate 5 is in contact with the bottom surface of the groove 201; in the second state, the upper surface of the lifting plate 5 is flush with the upper surface of the push-pull plate 4. It should be noted that in order to make it easier to see the position of the notch on the push-pull plate 4, Figure 4 and Figure 5 The position of the lifting plate 5 is adjusted.

[0031] During use, the lifting plate 5 is in the first state, and the lifting plate 5 is completely located in the groove 201, the upper surface of the lifting plate 5 is located below the bottom surface inside the shell 2, the bottom surface of the support foot of the motor body is in contact with the upper surface of the lifting plate 5, and the bottom surface of the support foot of the motor body is flush with the edge of the lifting plate 5, so that the motor body cannot move relative to the shell 2, which ensures the stability of the motor body during use; when the motor body needs to be maintained, the operator needs to take the motor body out of the shell 2. First, the lifting plate 5 is driven up by external force, so that the lifting plate 5 changes from the first state to the second state, so that the push-pull plate 4 is flush with the upper and lower surfaces of the lifting plate 5, that is, the push-pull plate 4 and the lifting plate 5 form an integral plate, and the motor body is placed on the integral plate. In this state, the operator pulls the push-pull plate 4 flatly again, and the push-pull plate 4, the lifting plate 5 and the motor body can be pulled out as a whole. After the motor body moves out of the shell 2 for a certain distance, the operator can easily take the motor body away for maintenance. After maintenance is completed, put the motor body back to its original position, that is, make the bottom surface of the motor body's support feet flush with the edge of the lifting plate 5, and then push the push-pull plate 4 back to its original position. Subsequently, the lifting plate 5 returns to the first state under the action of gravity, and the motor body also drops accordingly, entering a stable working state relative to the shell 2.

[0032] In fact, during the design process, in order to reduce the space occupied by the housing 2 as much as possible, and to reduce the gap between the housing 2 and the motor body to reduce resonance, the gap between the housing 2 and the motor body is often designed to be small, and it is difficult for operators to lift the motor body and move the motor body out of the housing 2 by hand. Based on this, the following design is made in this embodiment.

[0033] like Figure 2 and Figure 5 As shown, the shell 2 is provided with a lifting assembly 6 for lifting the lifting plate 5, and the lifting assembly 6 includes a lifting platform 601 slidably installed on the shell 2 in a direction perpendicular to the lifting plate 5, and upward protrusions are formed on both sides of the lifting platform 601, and the positions of the protrusions correspond to the grooves 201 one by one; round rods 602 are rotatably installed on the two side walls of the lifting platform 601, and guide rails 603 cooperating with the round rods 602 are slidably installed at the position of each guide rail 603 on the bottom surface of the shell 2, and the sliding direction of the guide rails 603 is parallel to the sliding direction of the push-pull plate 4; the guide rails 603 include horizontal sections and inclined sections, and the upper surface of the guide rails 603 is convex to form a T-shaped convex strip, and the bottom surface of the shell 2 is also provided with a T-shaped groove adapted thereto; a crossbeam 604 is fixedly installed between the two guide rails 603. Rollers 606 are rotatably installed on the upper surfaces of the protrusions on both sides of the lifting platform 601, and there are more than three rollers 606 on each side, and the upper vertices of each roller 606 are located in the same plane. The roller 606 is always in contact with the lower surface of the lifting plate 5 to reduce the friction force on the lifting plate 5 during translation.

[0034] When the motor body is in normal working state, the round rod 602 is located at the bottom end of the inclined section of the guide rail 603. When the guide rail 603 is not subjected to external force, the round rod 602 will not move up and down, and the lifting platform 601 and the lifting plate 5 will not move up and down. When the motor body needs to be taken out, the operator only needs to pull the crossbeam 604 outward to drive the two guide rails 603 to move synchronously. At this time, the inclined sections of the two guide rails 603 and the round rod 602 will generate an interaction force, so that the round rod 602, the lifting platform 601 and the lifting plate 5 rise. When the operator pulls the crossbeam 604 for a certain distance, the round rod 602 enters the horizontal section of the guide rail 603. At this time, the lifting plate 5 changes from the first state to the second state. The gravity of the motor body and the lifting plate 5 acts on the roller 606, so that the lifting platform 601 applies downward pressure to the guide rail 603 through the round rod 602, and the friction between the guide rail 603 and the housing 2 is greatly increased. At this time, the operator can pull the push-pull plate 4 horizontally, so that the push-pull plate 4, the lifting plate 5 and the motor body move horizontally out of the housing 2.

[0035] In summary, in this embodiment, the operator only needs to pull the crossbeam 604 horizontally to lift the motor body, without having to put his hand into the shell 2 to lift the motor body, which greatly improves the convenience of operation.

[0036] In actual operation, since the housing 2 is not in a horizontal state but has a certain tilt angle, and the push-pull plate 4 also has a certain tilt angle, when the operator pulls the push-pull plate 4 to a predetermined position and lets go to take the motor body in the next step, the push-pull plate 4 and the motor body will slide relative to the housing 2 under the action of gravity. If the opening end of the housing 2 is lower, the push-pull plate 4 and the motor body will continue to slide to the outside of the housing 2, and the operator can catch the motor body without affecting the next step; but if the opening end of the housing 2 is higher, the push-pull plate 4 and the motor body will slide to the inside of the housing 2, which will obviously affect the operator's taking of the motor body. Based on this, the present embodiment also designs the following structure to achieve self-locking of the motor body position for easy operation.

[0037] like Figure 2 and Figure 5As shown, a support rod 605 is fixedly installed on the guide rail 603, and a lifting column 7 is slidably installed in the vertical direction at the position corresponding to the support rod 605 on the push-pull plate 4. A convex block is formed on the top of the lifting column 7 to prevent the lifting column 7 from separating from the push-pull plate 4. When the motor body is working, the lifting column 7 is located inside the shell 2, and the bottom surface of the lifting column 7 is in contact with the inner bottom surface of the shell 2. The operator pulls the cross beam 604 outward to make the round rod 602 enter the horizontal section of the guide rail 603, and then pulls the push-pull plate 4 horizontally to make the lifting column 7 move horizontally to the outside of the shell 2, and the lifting column 7 moves downward under the action of gravity; then, the operator continues to pull the cross beam 604 outward to make the support rod 605 fit with the lifting column 7; as the operator continues to pull the cross beam 604 outward, the guide rail 603, the support rod 605, the lifting column 7, the push-pull plate 4 and the motor body will move outward synchronously until the motor body moves to a position convenient for the operator to take. Since the friction between the guide rail 603 and the housing 2 is very large, it is difficult for the guide rail 603 to move relative to the housing 2 under the action of external force. Therefore, after the operator releases the crossbeam 604, even if the push-pull plate 4 and the motor body have a tendency to slide into the housing 2, the guide rail 603 and the support rod 605 will support the lifting column 7, the push-pull plate 4 and the motor body to prevent the motor body from moving into the housing 2, thereby relying on the motor body's own gravity to achieve self-locking of the motor body position. It should be noted that a rubber layer is provided on the upper surface of the lifting plate 5, so the friction between the lifting plate 5 and the motor body is very large, and the motor body will not move relative to the lifting plate 5.

[0038] like Figure 4 and Figure 5As shown, the motor housing assembly also includes an end cover 8 that cooperates with the open end of the shell 2, and the end cover 8 is connected to the shell 2 by bolts; a limit plate 9 is slidably installed on the side wall of the shell 2, and the lower surface of the limit plate 9 is flush with the upper surface of the push-pull plate 4; when the lifting plate 5 is in the first state, the upper surface of the supporting foot of the motor body is flush with the upper surface of the push-pull plate 4; the side of the limit plate 9 facing the end cover 8 is an inclined surface, and a push rod 10 is fixedly installed at the position corresponding to the limit plate 9 on the end cover 8, and the end of the push rod 10 facing the limit plate 9 is an inclined surface. After the motor body is installed in the housing 2, the operator aligns the end cover 8 with the open end of the housing 2, and then pushes the end cover 8 to a position that fits with the housing 2, and pushes the end cover 8 to a predetermined installation position. During this process, the push rod 10 contacts the limit plate 9, specifically, the inclined surface of the push rod 10 contacts the inclined surface of the limit plate 9, and the push rod 10 pushes the limit plate 9 to move inward, so that the lower surface of the limit plate 9 fits with the upper surface of the support foot of the motor body (in this state, the inner end of the limit plate 9 fits with the side wall of the support foot of the motor body), and then the end cover 8 is connected to the housing 2 by bolts. In this way, during the working process, since the push rod 10 is always pressed against the limit plate 9, the position of the limit plate 9 relative to the housing 2 remains unchanged, that is, the limit plate 9 can always limit the motor body to prevent the motor body from slightly jumping due to the vibration generated during operation.

[0039] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
