Embodiment Construction
[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0026] Such as Figure 2 to Figure 4 As shown, the present invention provides a centrifugal compressor guide vane drive connection mechanism, including: an electric actuator 10 and a drive shaft 30 arranged in the compressor housing 20, and a leading vane shaft 50 connected to the drive shaft 30 ( The main vane shaft is integrated with the main vane), wherein the actuator output shaft 11 of the electric actuator 10 is coaxially connected with the drive shaft 30 . The coaxial transmission connection between the actuator output shaft 11 and the drive shaft 30 of the electric actuator 10 can simplify the transmission parts between the actuator output shaft 11 and the drive shaft 30, and can omit the traditional connecting rod transmission mode, so that...

The invention provides a guide vane driving connection mechanism for a centrifugal compressor. The guide vane driving connection mechanism comprises an electric actuator, a driving shaft arranged in a compressor shell and a main guide vane stem connected with the driving shaft, wherein an actuator output shaft of the electric actuator is in coaxial transmission connection with the driving shaft. According to the guide vane driving connection mechanism for the centrifugal compressor, the actuator output shaft of the electric actuator is in coaxial transmission connection with the driving shaft, so that the conventional link transmission mechanism can be eliminated, an intermediate transmission link can be eliminated, the transmission efficiency, the working efficiency and the reliability of a guide vane of the compressor are greatly improved, and the manufacture and assembly cost is lowered; and in addition, a compressor body is independent, and the guide vane is arranged on the compressor shell after being arranged on the compressor body, so that an assembly adjustment space is enlarged, and the assembly quality is easily ensured.
Description
technical field [0001] The invention relates to the field of air-conditioning and refrigeration equipment, in particular to a drive connection mechanism for guide vanes of a centrifugal compressor. Background technique [0002] For centrifugal compressors, the guide vane adjustment mechanism is an important mechanism to realize the control of the intake air volume of the refrigerant, and then achieve the control of the cooling capacity. Such as figure 1 As shown, the commonly used guide vane driving is driven by the electric actuator through the connecting rod transmission mechanism to drive the guide vane drive shaft 1, and the guide vane drive shaft 1 drives the leading vane shaft 5 to rotate through the gear transmission mechanism 3, and the leading vane shaft 5 is driven by The ring drives the other guide vanes to rotate. This driving connection structure is relatively complicated, and there are many transmission links, resulting in poor reliability and low transmissio...
