Description

Braking device for rotating electric machines

This case relates to a braking device for a rotating electrical machine, specifically a braking device applied to a rotating electrical machine to provide an axial limit for the brake pad to prevent wear and noise from occurring during the rotation of the brake pad.

Traditionally, the braking device of the rotating electrical machine can be divided into two functions: dynamic type and holding type. When the rotating electrical machine is powered off, the rotor of the rotating electrical machine will rotate for a while due to inertia before completely stopping. In the application of rotating electrical machines in many industries, if the rotating electrical machine needs to be stopped immediately after power failure, a dynamic braking device is required to achieve this. When the rotating motor stops rotating, if it is necessary to ensure that the load end does not rotate or become loose, a holding brake is required at this time. The braking device of a general rotating electrical machine is composed of a base body, a sliding plate, a brake piece, an upper plate and a square iron (or spline). The base body is locked on the frame of the rotating electrical machine, and there are coils and springs in the base body. The formed driver module. When the drive module is powered on, the electromagnetic force of the coil generates suction, which attracts the sliding plate and attaches it to the base, so that the freeing piece between the upper plate and the sliding plate has the freedom to rotate, and the freeing piece and the square iron (or spline) and the rotor will rotate together after assembly. When the drive module is powered off, the sliding plate that has lost its magnetic adhesion is pushed up by the spring. The sliding plate will push the slider up to the upper plate, and the slider will lose the freedom of rotation due to the clamping of the sliding plate and the upper plate. , stopping the rotation of the rotor by connecting with the square iron (or spline).

However, when the drive module is energized and the rotor rotates, the diaphragm is not axially constrained, so it is easy for the diaphragm to move up and down, yaw, and wear due to the influence of gravity. The wear may produce noise and debris, which may contaminate the bearings and encoders, or cause the brakes to fail.

In view of this, it is necessary to provide a braking device for a rotating electric machine, which can provide an axial limit for the driving plate, so as to avoid the wear and noise generated by the driving plate during the rotation process, so as to solve the deficiencies of the conventional technology.

The purpose of this case is to provide a braking device applied to a rotating motor, which uses the axial limiting structure of the brake pad to avoid wear and noise from the brake pad during rotation. The axial limiting structure can be realized by adding plates, connectors and elastic components. The plate body maintains a fixed axial height of the piece through the connecting piece, and the elastic component provides an elastic force between the plate body and the transmission member, so that the plate body drives the piece to push the piece against the transmission member in the axial direction. Since the pad axially resists the transmission part and forms an axial constraint, when the transmission part drives the pad to rotate, it is less likely to cause the pad to move up and down or yaw due to the influence of gravity, causing wear. It also avoids the generation of noise and debris.

Another purpose of this case is to provide a braking device applied to a rotating electrical machine.

The braking device 1 includes a base 10 , an upper plate 20 , a sliding plate 30 , a transmission member 40 , a brake piece 50 , a connecting member 60 , a plate body 70 and an elastic component 80 . In this embodiment, the base 10 is, for example, an annular structure, and includes a driving module 11 and a base hollow portion 12 . The driving module 11 includes, for example, a spring component (not shown) and a coil component (not shown), which are respectively assembled to provide a thrust force and a magnetic attraction force. This case is not limited to this. In this embodiment, the rotating shaft 90 penetrates the hollow portion 12 of the base 10 along an axial direction C. The upper plate 20 is, for example, in a ring-shaped structure and has an upper plate hollow portion 21 . The upper plate 20 is spatially opposite to the base body 10 and is spaced apart along the axial direction C on the base body 10 . Similarly, the rotation shaft 90 penetrates the upper plate hollow portion 21 of the upper plate 20 along the axial direction C, for example. In this embodiment, the braking device 1 further includes, for example, a plurality of spacing columns 22 , wherein the plurality of spacing columns 22 are connected between the base 10 and the upper plate 20 so that the upper plate 20 and the base 10 maintain a fixed spacing height. . In addition, the sliding plate 30 is spatially relative to the base 10 and the upper plate 20 , for example, in an annular structure, and has a sliding plate hollow portion 31 . The rotation shaft 90 penetrates through the sliding plate hollow portion 31 of the sliding plate 30 along the axial direction C, for example.

It should be noted that the spring component of the driving module 11 is, for example, disposed between the base 10 and the sliding plate 30 , and the assembly provides a thrust force to drive the sliding plate 30 away from the base 10 . In addition, the coil component of the driving module 11 is, for example, embedded in the base 10 , and when energized, a magnetic attraction force is generated to drive the sliding plate 30 to adhere to the base 10 against the thrust provided by the spring component. In other words, in this embodiment, the sliding plate 30 can be driven by the driving module 11 to attach to or separate from the base 10 along the axial direction C. Of course, this case is not limited to the way in which the driving module 11 drives the sliding plate 30 to slide.

In this embodiment, the transmission member 40 can be, for example, a square iron or a spline, which is sleeved and fixed on the rotating shaft 90 to rotate synchronously with the rotating shaft 90 . The transmission member 40 includes a fitting peripheral edge 41 , a limiting portion 42 , a plurality of through holes 43 and a shaft hole 45 . The transmission member 40 is sleeved and fixed on the rotating shaft 90 through the shaft hole 45 . The fitting peripheral edge 41 is assembled and meshed with the latch piece 50 . The limiting portion 42 protrudes outward from the fitting peripheral edge 41 along a radial direction of the rotation axis 90 , for example, forming an annular boss. Of course, the portion of the limiting portion 42 that protrudes outward from the fitting peripheral edge 41 can be adjusted according to actual application requirements, and this case is not limited to this. In this example, the plurality of through holes 43 penetrate the upper surface 421 and the lower surface 422 of the limiting part 42 along the axial direction C. The pad 50 has a set of openings 51 . The coupling piece 50 passes through the fitting opening 51 and is fitted on the fitting peripheral edge 41 of the transmission member 40 along the axial direction C. In this embodiment, the fitting opening 51 of the coming piece 50 is, for example, greater than or equal to the fitting peripheral edge 41 of the transmission member 40. When the transmission member 40 is driven by the rotating shaft 90, the fitting opening 51 of the coming piece 50 and the transmission member 40 The fitting periphery 41 is engaged, and the piece 50 is carried on the upper surface 421 of the limiting portion 42 .

When the driving module 11 drives the sliding plate 30 to separate from the base 10 , the coming piece 50 is clamped by the sliding plate 30 and the upper plate 20 . The blocking transmission member 40 and the rotating shaft 90 are synchronously stationary. When the driving module 11 drives the sliding plate 30 to adhere to the base 10 , the piece 50 is separated from the sliding plate 30 and the upper plate 20 , so that the piece 50 regains its freedom of rotation and can be driven by the transmission member 40 to rotate.

It is worth noting that in this embodiment, the plate body 70 is spatially opposite to the backing plate 50 , and the plurality of connectors 60 are connected between the plate body 70 and the backing plate 50 through the plurality of through holes 43 of the transmission member 40 respectively. . In addition, the elastic component 80 is sleeved on the connecting member 60 and is disposed between the plate body 70 and the lower surface 422 of the limiting portion 42 of the transmission member 40 to provide an elastic force. In other words, the plate body 70 maintains a fixed axial height H through the connecting piece 60 and the lever 50 , and the elastic component 80 provides an elastic force between the plate body 70 and the lower surface 422 of the limiting portion 42 of the transmission member 40 , so that The plate body 70 can be driven to make the piece 50 push against the upper surface 421 of the limiting portion 42 of the transmission member 40 along the axial direction C. Since the camel piece 50 resists the limiting portion 42 of the transmission member 40 in the axial direction C to form a constraint in the axial direction C, when the transmission member 40 drives the comer piece 50 to rotate, it is less likely to be caused by the influence of gravity. 50 has the problem of wear caused by up and down movement and deflection, and it also avoids the generation of noise and debris.

In this embodiment, the plurality of connecting members 60 , the plurality of elastic components 80 and the plurality of through holes 43 of the transmission member 40 have the same number N, where N is an integer, and N is greater than or equal to 3. Thereby, the plate 50 and the plate body 70 connected through a plurality of connectors 60 of the same height can maintain a fixed height difference in the axial direction C. In this embodiment, the four through holes 43 are, for example, centered on the rotation axis 90 , and equidistant rings are provided on the limiting portion 42 . In other embodiments, the number and arrangement of the connecting members 60 and the through holes 43 can be adjusted according to actual application requirements, and this case is not limited thereto.

In addition, in this embodiment, each set of connecting members 60 includes a locking bolt 61 and a bushing 62. The bushing 62 is, for example, tubular, and passes through the corresponding through hole 43 on the limiting portion 42 of the transmission member 40. Connected between the backing piece 50 and the plate body 70 , the locking bolt 61 locks the backing piece 50 and the plate body 70 through the bushing 62 . In this embodiment, the bushing 62 has, for example, an axial height H that is greater than the distance from the upper surface 421 to the lower surface 422 of the limiting portion 42 of the transmission member 40 . That is, the axial height H of the bushing 62 is greater than the thickness T of the limiting portion 42 . In addition, in this embodiment, the strap 50 includes a plurality of first connection holes 52 that spatially correspond to the plurality of through holes 43 of the transmission member 40 . The plate body 70 has a plurality of second connection holes 72 that spatially correspond to the plurality of through holes 43 of the transmission member 40 . The locking bolt 61 of each connecting member 60 is locked through the corresponding first connecting hole 52 , the corresponding bushing 62 and the corresponding second connecting hole 72 , for example, with nuts at both ends to secure the piece 50 to the plate body. 70. The diameter d of the first connecting hole 52 and the second connecting hole 72 are both smaller than the diameter D of the bushing 62 . Thereby, when the locking bolt 61 uses, for example, nuts at both ends to lock the backing piece 50 and the plate body 70, the bushing 62 is clamped between the backing piece 50 and the plate body 70, so that the backing piece 50 and the plate body 70 are fixed. The body 70 can maintain a fixed axial height H through the support and connection of a plurality of bushings 62 .

On the other hand, in this embodiment, the elastic component 80 further includes, for example, a plurality of compression springs. Each compression spring is, for example, sleeved on the outer periphery of the bushing 62 so as to connect between the plate body 70 and the lower surface 422 of the limiting portion 42 . A uniform and stable elastic force is provided between them, and the plate body 70 can be driven through the connecting member 60 to make the piece 50 push against the upper surface 421 of the limiting part 42 along the axial direction C. Of course, this case is not limited to the form of the elastic component 80 . In other embodiments, the elastic component 80 may not be sleeved on the outer periphery of the bushing 62 , but may be disposed between the plate body 70 and the transmission member 40 . By providing elastic force, the plate body 70 can be driven through the connecting member 60 The piece 50 contacts the upper surface 421 of the limiting portion 42 along the axial direction C. This case is not limited to this and will not be described again.

It should be noted that in this embodiment, the base 10 , the upper plate 20 , the sliding plate 30 , the transmission member 40 and the lever 50 form a braking structure of the rotating shaft 90 to provide the braking function of the rotating shaft 90 . The braking device 1 in this case further adds a plate body 70 , a connecting piece 60 and an elastic component 80 to the plate 50 to further structure the axial limiting structure of the plate 50 . In this example, the base 10 , the sliding plate 30 and the upper plate 20 all form an annular structure, and the rotation axis 90 penetrates the hollow part 12 of the base, the hollow part 31 of the sliding plate and the hollow part 21 of the upper plate. The base 10 , the sliding plate 30 and the upper plate 20 do not affect the rotation of the rotating shaft 90 . It is worth noting that the axial limiting structure achieved by adding the plate body 70, the connecting piece 60 and the elastic component 80 to the plate 50 can be misaligned with the braking structure of the base body 10, the upper plate 20 and the sliding plate 30. settings. In this example, the base 10 is disposed in a misaligned position with the limiting portion 42 , the plate body 70 , the plurality of connectors 60 and the elastic component 80 in the axial direction C. The limiting part 42 , the plate body 70 , the plurality of connectors 60 and the elastic components 80 are, for example, accommodated in the space connected by the base body hollow part 12 , the sliding plate hollow part 31 and the upper plate hollow part 21 . Due to the axial limiting structure achieved by adding the plate body 70 , the connecting piece 60 and the elastic component 80 relative to the mounting piece 50 , the braking structures constructed with the base body 10 , the upper plate 20 and the sliding plate 30 can be disposed offset from each other. Therefore, the setting of the axial limiting structure will not increase the size of the overall structure, and effectively improves the stability and product competitiveness of the braking device 1. Of course, in other embodiments, the axial limiting structure achieved by adding the plate body 70 , the connecting piece 60 and the elastic component 80 relative to the freeing piece 50 can also be constructed on the base hollow part 12 , the sliding plate hollow part 31 and the upper part. outside the space connected by the plate hollow part 21. This case is not limited to this and will not be described again.

In addition, in this embodiment, the transmission member 40 further includes at least one locking hole 44 extending in the radial direction of the rotation axis 90 , and the braking device 1 includes at least one locking member (not shown) such as a screw. At least one locking member can lock the transmission member 40 on the rotating shaft 90 through at least one locking hole 44 . Thereby, when the transmission member 40 is sleeved on the rotating shaft 90 through the shaft hole 45, it is further locked on the rotating shaft 90, so that the transmission member 40 and the rotating shaft 90 can operate synchronously. Of course, in other embodiments, the fitting and fixing of the transmission member 40 and the rotating shaft 90 can be achieved in the form of engaging grooves or engaging keys. This case is not limited to this and will not be described again.

To sum up, this project provides a braking device applied to a rotating motor, which uses the axial limiting structure of the brake pad to avoid wear and noise from the brake pad during rotation. The axial limiting structure can be realized by adding plates, connectors and elastic components. The plate body maintains a fixed axial height of the piece through the connecting piece, and the elastic component provides an elastic force between the plate body and the transmission member, so that the plate body drives the piece to push the piece against the transmission member in the axial direction. Since the pad axially resists the transmission part and forms an axial constraint, when the transmission part drives the pad to rotate, it is less likely to cause the pad to move up and down or yaw due to the influence of gravity, causing wear. It also avoids the generation of noise and debris. In addition, the axial limiting structure realized by adding a plate body, connecting pieces and elastic components to the plate, and the braking structure of the base body, upper plate and sliding plate structure can be arranged in a misaligned position with each other. The plate body, connectors and elastic components are accommodated in the hollow part of the base body, so the axial limiting structure does not increase the size of the overall structure, effectively improving the stability of the braking device and product competitiveness.

This case may be modified in various ways by those who are familiar with this technology, but none of them will deviate from the intended protection within the scope of the patent application.
