The basic function of a slip ring in this context is to transmit energy or signals to a rotary apparatus. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a power supply device according to an embodiment of the present invention, as shown in fig. 1, the power supply device includes a slip ring and a transmission buffer device, and the slip ring includes a slip ring rotor 320 and a slip ring stator 310. One end of the transmission buffer device is connected to the end of the rotary apparatus 100, and the other end is connected to the slip ring rotor 320, the transmission buffer device is used to adjust at least one of the angular, axial and radial displacements between the rotary apparatus 100 and the slip ring, and the transmission buffer device is used to transmit the rotary motion of the rotary apparatus 100 to the slip ring rotor 320, so that the rotary apparatus 100 and the slip ring rotor 320 keep rotating synchronously.
The transmission buffer device may be a flexible connection shaft, one end of the flexible connection shaft is fixedly connected to the end of the rotary apparatus 100, and the other end of the flexible connection shaft is fixedly connected to the slip ring rotor 320 of the slip ring. When the rotary equipment 100 is in power transmission, adaptive steering or operation, the angle, axial or radial displacement caused by the up-and-down jumping generated can be compensated through the flexible connecting shaft; therefore, the rotary equipment 100 is ensured not to be greatly deviated, and the damage rate of the slip ring component is further reduced.
Preferably, the compensation function of the transmission buffer device is realized by a universal joint, which includes a first universal joint 210, one end of the first universal joint 210 is connected to the rotary apparatus 100, and the other end is connected to the slip ring rotor 320 of the slip ring. When the rotary apparatus 100 generates an angular or radial displacement with respect to the slip ring rotor 320, the first gimbal 210 compensates for the angular or radial displacement.
Preferably, in the case of compensating the angular or radial displacement of the rotary apparatus 100, the compensation of the axial displacement deviation between the rotary apparatus 100 and the slip ring rotor 320 can also be realized through the telescopic connecting shaft 220. In the power supply device with slip ring, the rotary apparatus 100 may generate a slight axial error with the slip ring rotor 320 as it rotates continuously for a long time, and if this is adjusted only by the universal joint, the adjustment effect may not be achieved; therefore, the connection shaft connecting the first universal joint 210 and the slip ring rotor 320 is provided as the telescopic connection shaft 220, and the slight expansion and contraction of the telescopic connection shaft 220 compensates for the axial play error between the rotary apparatus 100 and the slip ring rotor 320.
As shown in fig. 1 and 2, the telescopic connecting shaft 220 is disposed between the first gimbal 210 and the slip ring rotor 320; that is, one end of the telescopic connecting shaft 220 is connected to the first gimbal 210, and the other end may be connected to the slip ring rotor 320. During the continuous operation of the rotary apparatus 100, the axial offset caused by the expansion and contraction of the rotary apparatus 100 or the slip ring and the continuous rotation of the rotary apparatus can be compensated by the telescopic connecting shaft 220.
Preferably, the transmission damping device further comprises a second universal joint 230. Second universal joint 230 is located between telescoping connection shaft 220 and slip ring rotor 320. Universal joints are arranged at two ends of the telescopic connecting shaft 220, so that included angles at two ends of the telescopic connecting shaft 220 are equal, and the angular speeds of the slip ring rotor 320 and the rotary equipment 100 are always equal. Compared with the situation that a universal joint is arranged at one end of the telescopic connecting shaft 220, the method effectively solves the problem of position deviation of the rotary equipment 100 caused by expansion and contraction or continuous rotation, and therefore the angular speeds of the slip ring rotor 320 and the rotary equipment are equal. In order to simplify the installation process, the telescopic connection shaft 220 may be a structure integrated with the first universal joint 210 or the second universal joint 230, so that the telescopic connection shaft 220 may be further connected with another member. And the connection between the two can be realized through a key, and besides, the connection can also be realized through a detachable mode such as a screw or a bolt.
However, it should be understood that, in order to ensure that the rotary apparatus 100 and the slip ring rotor 320 rotate at the same speed, other constant speed universal joints, such as a ball and socket joint, may be used instead of providing one universal joint at each end of the telescopic connecting shaft 220. Since the ball-and-fork universal joint itself has a characteristic of rotating the output shaft and the input shaft at a constant speed, matching the ball-and-fork universal joint with the telescopic connecting shaft 220 in the power supply apparatus not only can adjust the displacement deviation between the rotary apparatus 100 and the slip ring, but also can ensure that the angular velocities of the rotary apparatus 100 and the slip ring rotor 320 are equal.
In addition, the first and second universal joints 210 and 230 located at both ends of the telescopic connecting shaft 220 may be embodied as rigid or flexible universal joints. Rigid joints are joints which are not significantly elastic in the torsional direction, such as constant velocity joints and the like. The flexible universal joint has certain elasticity in the torsion direction, and the angle error between the two rotary parts is made up mainly by the elastic deformation of the elastic element; however, it should be noted that the flexible universal joint is generally used in the case of small included angle between two shafts and only a small amount of displacement because the elastic deformation of the elastic member is limited.
The rotary apparatus 100 may be embodied as a fermentation drum, which is cylindrical. A first connecting shaft 500 may be additionally installed between the end of the cylindrical drum and the first gimbal 210, one end of the first connecting shaft 500 is connected to the first gimbal 210, and the other end is connected to the end of the rotary apparatus 100. As shown in fig. 2, a protruding fixing seat 110 may be specifically disposed at a central position of the end of the rotary apparatus 100, and an end of the first connecting shaft 500 is connected to the fixing seat 110 by a screw or a bolt. The convex fixing seat 110 may be fixed to the end of the fermentation cylinder by welding, or may be formed integrally with the fermentation cylinder. Further, the other end of the first connecting shaft 500 is connected to the first universal joint 210 by a key. Preferably, the first connecting shaft 500 is arranged to coincide with the axis of the cylindrical drum, i.e., the fermenting drum makes a revolving motion around the axis of the first connecting shaft 500.
Further, the second universal joint 230 and the slip ring rotor 320 may be connected by a second connection shaft 600. One end of the second connection shaft 600 is connected to the second universal joint 230 through a key, and the other end of the second connection shaft 600 may be fixed to the end of the slip ring rotor 320 through a screw or a bolt, so as to ensure that the rotational motion of the rotary apparatus 100 is transmitted to the slip ring rotor 320 through the first connection shaft 500, the first universal joint 210, the telescopic connection shaft 220, the second universal joint 230, and the second connection shaft 600 in sequence, and the slip ring rotor 320 and the rotary apparatus 100 perform synchronous rotational motion.
Preferably, the power supply device further includes a housing 400. A slip ring may be fixed to the frame 400. One side of a slip ring stator 310 of the slip ring is provided with four electrode input ends, and one end of a slip ring rotor 320 is provided with four output ends; and the four electrode input ends are respectively connected with four groups of coils inside the slip ring, and the further four groups of coils are respectively connected with four output ends at the end part of the slip ring rotor 320. In a specific electric power or signal transmission process, four power supply lines located outside the slip ring are connected to four electrode ends of the slip ring stator 310, pass through four groups of coils inside the slip ring, and finally are output through four output ends at the end of the slip ring rotor 320. The number of the electrode input ends on one side of the slip ring stator 310 may be set according to actual needs, and the number of the coils inside the slip ring and the number of the output ends at the end of the slip ring rotor 320 may be changed correspondingly according to the number of the electrode input ends. Further, the power supply device further includes a bearing and a bearing seat 410. The bearing housing 410 may be fixed to the frame 400, and cooperate with a bearing to rotatably support the second connection shaft 600.
In the power supply apparatus, the rotary apparatus 100 may be an internal driving apparatus or an external driving apparatus. When the rotary equipment 100 is an internal driving equipment, the slip ring can be used for transmitting electric energy; such as power slip rings. When the slip ring rotor 320 is used specifically, an external cable can be connected with an electrode of the slip ring stator 310, the electrode of the slip ring stator 310 is connected with a coil inside the slip ring rotor 320, and power supply output is performed through one end of the slip ring rotor 320; the cable output from the slip ring rotor 320 sequentially passes through the second connection shaft 600, the second universal joint 230, the telescopic connection shaft 220, the first universal joint 210, and the first connection shaft 500 to reach the rotary apparatus, and then the cable is connected to a driving part inside the rotary apparatus 100. Therefore, during the rotation of the rotary apparatus 100, the slip ring rotor 320 rotates synchronously with the rotary apparatus 100 to solve the problem that the rotary apparatus 100 generates a winding during the rotation.
When the rotary apparatus 100 is an external driving apparatus, the slip ring may also function as a signal transmission device in the power supply apparatus. The external driving component drives the rotary equipment 100 to rotate; while the other signal lines placed inside the rotary apparatus 100 are transmitted by means of slip rings. For example, sensors may be further installed in the rotating parts of the rotary apparatus 100, and signal transmission lines of the respective sensors are sequentially introduced into the rotary apparatus 100 through the slip ring stator 310, the slip ring rotor 320, the second connecting shaft 600, the second universal joint 230, the telescopic connecting shaft 220, the first universal joint 210 and the first connecting shaft 500, and are connected to the sensors in the rotary apparatus 100; at this time, the slip ring serves as a part for transmitting signals, and prevents the signal transmission line from being wound during the rotation of the rotary apparatus 100.
