Description

Technical Field

[0001] The invention relates to the technical field of coupling equipment, in particular to a centering structure of a coupling with a brake wheel. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part. The two shafts rotate together during the transmission of motion and power and do not disengage under normal circumstances. It can not only transmit torque and motion, but also compensate for displacement, absorb vibration and shock, and protect mechanical systems. It is sometimes also used as a safety device to prevent the connected parts from being subjected to excessive loads, thus playing the role of overload protection.

[0003] Traditional couplings mostly use rigid locking during use and do not have the function of absorbing energy. Especially under large load movement, the traditional coupling connection needs to withstand huge stress, and long-term operation will cause serious wear and tear, affecting its service life. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a centering structure of a coupling with a brake wheel, which solves the problem that the connection of the traditional coupling needs to withstand huge stress and will be severely worn after long-term operation, thus affecting its service life.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a centering structure with a brake wheel coupling, comprising a locking cylinder, a hydraulic chamber is opened inside the locking cylinder, the hydraulic chamber is filled with hydraulic oil, the outer wall of the locking cylinder is connected to a plurality of negative pressure channels, a plurality of negative pressure channels are each provided with a negative pressure plate, a plurality of negative pressure plates are each fixedly connected to a connecting rod on the side walls away from the hydraulic chamber, a transmission block is fixedly connected to a transmission block at one end of the connecting rod away from the negative pressure plate, a plurality of mounting boxes are each fixedly connected to the outer wall of the locking cylinder, a plurality of mounting boxes are respectively covered on the outer surfaces of a plurality of transmission blocks, a plurality of mounting boxes are each provided with an adjusting screw, and a plurality of One end of the adjusting screw is rotatably connected to the inner wall of the mounting box through a bearing, and the other ends of the plurality of adjusting screws penetrate the mounting box, extend to the outside thereof and are fixedly connected to an adjusting wheel, the outer surfaces of the plurality of adjusting screws are threadedly sleeved with a driving block, the side wall of the driving block away from the transmission block is slidably connected to the inner wall of the mounting box, the inner wall of the locking cylinder is connected to a plurality of pressure transmission channels, a plurality of pressure transmission channels are internally provided with a pressure transmission plate, a plurality of side walls of the pressure transmission plates away from the hydraulic chamber are fixedly connected to a pressure transmission rod, one end of the plurality of pressure transmission rods away from the pressure transmission plate extends to the outside of the pressure transmission channel and is fixedly connected to the locking plate, and the side wall away from the pressure transmission rod is fixedly connected to two groups of locking protrusions.

[0006] Preferably, the transmission block and the driving block are both right-angled trapezoids in side view, and the hypotenuses of the two are in contact.

[0007] Working principle: When in use, place the two shafts to be connected between multiple locking plates, then rotate any adjusting wheel. Since the drive block is threadedly sleeved on the outer surface of the adjusting screw, and the drive block is away from the side wall of the transmission block and is slidably connected to the inner wall of the mounting box, when the adjusting screw rotates, the drive block will move along the direction in which the adjusting screw extends. Since the side views of the transmission block and the drive block are both right-angled trapezoids, and the hypotenuse of the two is in contact, the solid drive block will drive the transmission block to pass the pressure through the connecting rod and the negative pressure plate through the hydraulic oil filled in the hydraulic cavity to each locking plate, and the shaft to be limited will be locked from multiple directions. Tight, due to the provision of multiple adjustment screws and drive blocks, multi-speed adjustment can be achieved, providing different locking forces in multiple directions. The locking force can be flexibly adjusted according to work needs to adapt to various processing environments. In the course of work, when a certain angle of an axis is subjected to excessive force, the pressure will be distributed to other locking plates through the hydraulic chamber, thereby achieving the effect of pressure distribution. Locking by hydraulic means can not only provide precise centering settings, but also due to the characteristics of liquid transmitting pressure, it will distribute excessive energy in local areas during operation, and has a good protection effect on the axis and the structure itself.

[0008] (III) Beneficial effects The present invention provides a centering structure with a brake wheel coupling. It has the following beneficial effects: 1. The centering structure of the coupling with a brake wheel, since the side views of the transmission block and the drive block are both right-angled trapezoids, and the hypotenuse of the two is in contact, the solid drive block will drive the transmission block to transmit the pressure to each locking plate through the connecting rod and the negative pressure plate through the hydraulic oil filled in the hydraulic chamber to lock the axis to be limited from multiple directions. Since multiple adjusting screws and drive blocks are provided, multi-speed adjustment can be achieved, providing different locking forces in multiple directions. The locking force can be flexibly adjusted according to work needs to adapt to various processing environments.

[0009] 2. The centering structure of the coupling with brake wheel, during operation, when a certain angle of a shaft is subjected to excessive force, the pressure will be distributed to other locking plates through the hydraulic chamber, thereby achieving the effect of pressure distribution. Locking by hydraulic means can not only provide precise centering settings, but also due to the characteristics of liquid pressure transmission, it will distribute excessive energy in local areas during operation, and has a good protective effect on the shaft and the structure itself.
