Problems solved by technology

At present, there are relatively few researches on the operating state of the diaphragm coupling under the extreme working condition. In the invention patent CN201310523726, an elastic coupling working condition test bench is proposed, but the adjustment of the extreme angular offset is relatively difficult. It is cumbersome, and the accuracy of angular offset is difficult to guarantee

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] like figure 1 As shown, the present invention adopts the diaphragm coupling that first adjusts the static angular deviation of the diaphragm coupling and then adjusts the angular deviation in place when performing the static angular deflection fatigue test on the diaphragm coupling. Methods of performing fatigue tests. The test bench is composed of two parts: the diaphragm coupling test mechanism and the diaphragm coupling angular offset adjustment mechanism. The diaphragm coupling test mechanism includes the frequency conversion main input motor 1, the first coupling 2, the first torque Instrument 3, first torque meter support 4, second coupling 5, first transmission shaft 6, first rolling bearing support 7, tested diaphragm coupling 8, second transmission shaft 10, third coupling 11 , the second torque meter 12, the second torque meter bracke...

Abstract

The invention discloses a static diaphragm coupler angular deviation fatigue testing bed. The static diaphragm coupler angular deviation fatigue testing bed comprises a diaphragm coupler testing mechanism and an annular deviation adjusting mechanism. The diaphragm coupler testing mechanism is mainly composed of a frequency conversion main input motor, a first coupler, a first torque meter, a first torque meter support, a second coupler, a first transmission shaft, a first bearing support, a second transmission shaft, a third coupler, a second torque meter, a second torque meter support, a fourth coupler, an universal transmission shaft, a fifth coupler and a frequency conversion loading motor. The annular deviation adjusting mechanism is mainly composed of a second bearing support, a hand-cranking handle, a rotating rack, a positioning pin, a transmission worm support and a transmission worm. According to the static diaphragm coupler angular deviation fatigue testing bed, the diaphragm coupler angular deviation is measured, the adjusting precision of the diaphragm coupler angular deviation is ensured, a static diaphragm coupler angular deviation fatigue test can be carried out through the diaphragm coupler testing mechanism, the rotating speed and the torque can be collected in real time through the torque meters connected with the transmission shafts at the two ends of a diaphragm coupler, and therefore the stress states of the two ends of the diaphragm coupler can be analyzed.

Description

technical field [0001] The invention relates to a fatigue test bench, in particular to a static angular offset fatigue test bench of a diaphragm coupling. Background technique [0002] Diaphragm couplings are connected by several sets of diaphragms (stainless steel sheets) interlaced with the two halves of the coupling with bolts. Each set of diaphragms is composed of several stacked pieces. Diaphragms are divided into connecting rod type and different shapes. the whole piece. The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate the relative displacement of the connected two shafts, which can compensate the shaft displacement caused by the manufacturing error, installation error, bearing deformation and temperature rise change between the main machine and the driven machine. radial, radial and angular offsets. Among them, when the angular offset is close to the allowable limit range, it will cause a large change in the force state of the ...
