Feedback control axial friction soft start coupling

Abstract

The invention relates to a feedback control axial friction soft start coupling which comprises a driving stage flange through connection end cover, a driving stage shell, a driving stage flange gland,a driving stage centrifugal wedge, a driving stage friction plate, a driving stage pressurizing wedge, a driven stage pressurizing wedge, a driven stage friction plate, a driven stage centrifugal wedge, an oil gas coupling damping member and a driven stage output shaft, wherein the oil gas coupling damping member provides damping buffer for the driven stage centrifugal wedge; the oil gas couplingdamping member comprises an outer barrel, an outer barrel gland, an inner barrel, an inner barrel guiding end cover, a floating piston, an inner barrel gland, a piston follower and a damping valve block; an air chamber, a rodless oil cavity and a rod oil cavity are arranged in the oil gas coupling damping member, a liquid penetrating damping hole is formed in the piston follower, a damping valveblock is located in the liquid penetrating damping hole, and a buffer spring is connected between the piston follower and the inner barrel guiding end cover. By introducing a theory of hydraulic-mechanical coupling for the first time, a conventional damping spring is replaced by the oil gas coupling damping member, so that the buffer performance is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of starting couplers, in particular to a feedback-controlled axial friction soft-starting coupler. Background technique [0002] With the development of society and the advancement of science and technology, the manufacturing precision of mechanical parts is also continuously improved. The parts of various working mechanisms are becoming more and more sensitive to the fluctuation of load changes. Any small change in load fluctuations may be like The butterfly effect also has a very large impact on the entire working system, which means that the requirements for the running stability of the prime mover are getting higher and higher, but most of the starting couplers are rigid connections, and rigid load starting has obvious disadvantages. There will be direct or indirect damage to the prime mover and working mechanism, which is mainly manifested in the following two points: [0003] (1) When the working mech...

Problems solved by technology

[0003] (1) When the working mechanism is started, it will carry a large load, which means that a larger moment of inertia is required, even exceeding the starting torque of the prime mover, and such a start is an overload start, which may Make the prime mover generate a large amount of starting current, and then impact the prime mover itself, which will not only reduce the working performance of the prime mover, but also shorten the service life of the prime mover;

[0004] (2) When the working mechanism is a precision instrument, since the precision instrument becomes more and more sensitive to the instability of the workload, any small unstable change may cause serious interference to the function of the entire working system, and The prime mover needs to bear a high load torque during the start-up phase, and the buffer time is also very short. In this case, the mechanical part of the prime mover will bear a large impact, which will not only directly affect the life of the entire working system and duty cycle, it will also cause the device not to work properly
