Device for reducing residual rotation angle of rotating equipment

Abstract

The invention discloses a device for reducing a residual rotation angle of rotating equipment. The device comprises a plurality of groups of protecting assemblies which are arranged on an external cylinder body of the rotating equipment in pairs; each protecting assembly comprises a rounded angle nut, transverse beams are arranged above each rounded angle nut, and a rubber member is arranged below each rounded angle nut; a quadrate frame is arranged at the outer portion of each rubber member; one ends of studs penetrate through the quadrate frames, the rubber members and the rounded angle nuts in sequence and are connected to the rounded angle nuts through threads; the other ends of the studs penetrate through upper lugs of the rotating equipment, moreover, guide sleeves are arranged outside stud bodies, extending out from the upper lugs, of the studs in a sleeving mode, and the guide sleeves and the upper lugs are fastened by nuts arranged at the tail ends of the studs. According to the device for reducing the residual rotation angle of the rotating equipment, related structures of a protecting unit of a device are designed optimally, the residual rotation angle of the rotating equipment is reduced effectively, and collision impact in the torsional resilience process is reduced, so that the endoergic process of the protecting unit is optimized, and the endoergic effect is more obvious.

Description

Technical field [0001] The invention belongs to a device for optimizing the assembly parts of a rotating equipment, and in particular relates to a device for reducing the remaining angle of the rotating equipment. Background technique [0002] The rotating equipment is designed with a set of protection devices. Its main function is to appropriately limit the torsion and jump of the failed machine when a certain rotating equipment fails, so as to absorb the energy released by the failed equipment, thereby reducing the vibration and impact generated by the failed rotating equipment. Ensure the safe operation of other machines in the system. Rotating equipment is a high-speed rotating machine, which is composed of high-speed rotating rotating parts. During its high-speed operation, the failure of internal rotating parts will inevitably occur. During the failure process of the rotating equipment, its rotating parts collide with the outer cylinder, so that most of the energy is tran...

Problems solved by technology

However, when the rubber is compressed to the limit position and rebounds (returns to the initial state), the nut 1 will move toward the center hole of the beam. Because the original boss of the nut 1 is too long and has no arc shape structure, the nut 1 directly collided with the beam and could not enter the center hole smoothly, and this process had a greater impact on the beam and other related equipment
