The utility model relates to photovoltaic support technical field discloses a section steel connecting structure, including C type steel subassembly and no curling C type steel, C type steel subassembly includes first C type steel and second C type steel, the web of no curling C type steel is set up with the curling of first C type steel adaptation's bayonet, the two flanges of no curling C type steel all are set up with the flange of first C type steel adaptation's first gap, the first C type steel is set up with the second gap of first gap one -to -one correspondence and the clamping cooperation, the curling of first C type steel includes the clamping portion between two first gaps, this clamping portion and bayonet clamping cooperation, first C type steel, second C type steel and no curling C type steel are connected through fastening assembly. Through setting up with the bayonet and first gap of first C type steel adaptation on no curling C type steel, cooperate corresponding second gap on first C type steel, form double positioning clamping structure, can promote the stability and carrying capacity of section steel connecting structure.

The utility model provides a kind of rotary compressor and the air conditioner with the rotary compressor of this utility model.The compressor includes: shell;Motor, including rotor;And compression assembly, including crankshaft, crankshaft is set to be fixedly connected with rotor, to make crankshaft rotate under the drive of motor;Wherein, crankshaft includes main body and, at least one eccentric portion is spacedly distributed along the axial direction of main body;And the axial end surface of rotor is provided with at least one lightening groove, to balance the eccentric force formed by at least one eccentric portion.This application can balance the eccentric force generated by eccentric portion rotation by setting lightening groove on rotor, while avoiding the weight of whole machine, so that the radial stress of crankshaft and roller and other transmission components under static and dynamic is greatly reduced, especially under dynamic, reduce the vibration and operating noise of whole machine caused by imbalance, reduce energy consumption while prolong the service life of core components.

The present disclosure relates to the technical field of electromagnetic bearing, and particularly relates to an electromagnetic bearing rotor system, which comprises a rotating shaft and a mounting base, the mounting base is coaxially provided with an electromagnetic bearing assembly and an auxiliary bearing assembly, the rotating shaft is arranged through the electromagnetic bearing assembly and the auxiliary bearing assembly; the auxiliary bearing assembly comprises an outer ring valve seat, an inner ring valve seat and an auxiliary bearing, the outer ring valve seat is connected with an outer ring of the auxiliary bearing, and the inner ring valve seat is connected with an inner ring; a gap is formed between the outer ring valve seat and the mounting base along the axial direction of the rotating shaft, an elastic member is arranged in the gap, a connecting hole for the rotating shaft is arranged on the inner ring valve seat, an abutting surface is formed on the wall of the connecting hole, the abutting surface is inclinedly extended along the axial direction of the rotating shaft and away from the rotating shaft, the rotating shaft is abutted with the abutting surface, so that the axial and radial loads are balanced through the elastic member, the auxiliary bearing is protected, the supporting effect of the auxiliary bearing assembly on the rotating shaft is further improved, and the electromagnetic bearing assembly is better protected.
