Example one
As shown in fig. 1 and 2, the present embodiment provides an encoder buffer mechanism, which includes two brackets 1, where the two brackets 1 are disposed perpendicular to each other in the same plane. The bracket 1 includes a first connection portion 11, an elastic portion 12, and a second connection portion 13 connected in sequence, the first connection portion 11 is configured to be detachably connected to a housing of the encoder 100, and the second connection portion 13 is configured to be detachably connected to a housing of the generator. The elastic part 12 can be deformed in a radial direction of the rotor of the generator; and/or the elastic portion 12 can be deformed telescopically in the axial direction of the rotor of the generator.
The encoder buffer mechanism provided by the embodiment utilizes two supports 1 which are perpendicular to each other in the same plane, and enables the first connecting part 11 of the support 1 to be detachably connected with the shell of the encoder 100, the second connecting part 13 to be detachably connected with the shell of the generator, and simultaneously enables the elastic part 12 to be capable of being telescopically deformed along the radial direction of the rotor of the generator and/or the elastic part 12 to be capable of being telescopically deformed along the axial direction of the rotor of the generator. When the rotor vibration of the generator causes the vibration of the rotating part of the encoder 100, because the elastic part 12 can stretch and deform, the casing 100 of the encoder can also move along the vibration direction along with the rotating part of the encoder 100, thereby effectively preventing the large acting force from being generated between the rotating part of the encoder 100 and the casing of the encoder 100, prolonging the service life of the encoder 100 and effectively avoiding the occurrence of the situation that the encoder 100 is damaged due to the vibration.
Preferably, in the present embodiment, the maximum radial deformation amount of the elastic portion 12 is larger than the radial amplitude of the rotor. As shown in fig. 1, with the extending direction of one of the brackets 1 being an x-axis and the extending direction of the other bracket 1 being a y-axis, if the maximum extension amount and the maximum compression amount of the elastic part 12 of each bracket 1 are both R, that is, the maximum deformation amount of the elastic part 12 is R, the encoder 100 can move in a circle of x2+ y2 ═ R2, and the rotor of the generator generally vibrates in a circle with a certain radius R, that is, the amplitude of the rotor is R, and when the radially movable range of the encoder 100 is larger than the radial vibration range of the rotor of the generator, that is, R > R, during the operation of the generator, the rotating part of the encoder 100, the housing of the encoder 100, and the rotor of the generator can be relatively stationary in the radial direction, so that no large force will be generated between the rotating part of the encoder 100 and the housing of the encoder 100.
It should be noted that the elastic portion 12 provided in this embodiment can mainly deform in an extension or compression manner along the radial direction of the rotor, and can also deform a small amount along the axial direction of the rotor, and is mainly suitable for a generator in which the rotor vibrates largely in the radial direction and vibrates less in the axial direction.
Preferably, the elastic portion 12 extends in an S-shaped bend in the radial direction of the rotor. The S-shaped bend can achieve a good buffering effect, and effectively prevents a large vibration acting force from being generated between the rotating part of the encoder 100 and the shell of the encoder 100.
Optionally, the first connection portion 11 has a circular ring shape to fit the shape of the end of the encoder 100.
Alternatively, the first connecting portion 11 is provided with a connecting hole 111, and a fastener can be detachably connected to the housing of the encoder 100 through the connecting hole 111. Specifically, the fastener is a bolt. Preferably, the plurality of connection holes 111 are uniformly distributed along a circumferential direction of the first connection portion 11 to ensure stability of connection of the first connection portion 11 with the encoder 100.
Optionally, a waist-shaped hole 131 is formed in the second connecting portion 13, and a fastener can be detachably connected with the housing of the generator through the waist-shaped hole 131. Through setting up waist shape hole 131, be convenient for adjust the position that support 1 fixed on the generator. Further, the number of the waist-shaped holes 131 is plural. Specifically, in the present embodiment, the number of the waist-shaped holes 131 is two, and the two waist-shaped holes 131 are aligned in the extending direction of the second connecting portion 13.
Further, the second connecting portion 13 is further provided with a mounting hole 132, and a fastener can be detachably connected with the housing of the generator through the mounting hole 132.
Preferably, the bracket 1 is of an integrally formed structure. The integrally formed bracket 1 has good structural stability and long service life. Alternatively, the bracket 1 is made of a stainless steel material. Further, the bracket 1 is formed by bending metal or formed in one step by a mold. Of course, the bracket 1 may be made of non-metal material, and is not limited herein.
Example two
The present embodiment provides another encoder buffer mechanism, and is different from the first embodiment in the structure of the elastic portion 12.
Specifically, as shown in fig. 3, the maximum axial deformation amount of the elastic portion 12 is larger than the axial amplitude of the rotor. I.e., the axially movable range of the encoder 100 is greater than the axial vibration range of the generator rotor, the rotating parts of the encoder 100, the housing of the encoder 100 and the rotor of the generator can be relatively stationary in the axial direction during operation of the generator, so that no significant force will be generated between the rotating parts of the encoder 100 and the housing of the encoder 100. Preferably, the elastic portion 12 extends in an S-shaped bend in the axial direction of the rotor.
The elastic portion 12 provided in this embodiment can be mainly subjected to extension or compression deformation in the axial direction of the rotor, and can also be subjected to a small amount of deformation in the radial direction of the rotor, and is mainly suitable for a generator in which the rotor vibrates largely in the axial direction and vibrates little in the radial direction.
EXAMPLE III
In the present embodiment, another encoder buffer mechanism is provided, and the structure of the elastic part 12 in the first embodiment and the structure of the elastic part 12 in the second embodiment are combined, that is, the elastic part 12 provided in the present embodiment can generate large extension or compression deformation along the radial direction of the rotor, and can also generate large extension or compression deformation along the axial direction of the rotor. Specifically, the elastic portion 12 provided in this embodiment includes two portions, one of which extends in an S-shaped bending manner along the radial direction of the rotor, and the other of which extends in an S-shaped bending manner along the axial direction of the rotor.
