Adapter connecting spiral lobe compressor and motor

Abstract

The invention relates to an F25B refrigerating machine, a refrigeration equipment or system classification of an international patent classification (IPC), and particularly belongs to an adapter connecting a spiral lobe compressor and a motor. The technical scheme includes that a motor end flange (1) is connected with a compressor end flange (5) through a middle body (4) to form the adapter connecting spiral lobe compressor and the motor, wherein a motor locating groove (2) and a bolt hole (3) are formed in the motor end flange (1), a ventilation port (41) and an observation port (42) are formed in the middle body (4), and a compressor locating pin hole (6) and a bolt hole (3) are formed in the compressor end flange (5). The adapter connecting the spiral lobe compressor and the motor has the advantages that connection coaxiality of a motor shaft and a compressor shaft can be guaranteed, connecting distance between a motor shaft end and a compressor shaft end is reduced, usage safety is guaranteed, and meanwhile, according to the adapter the spiral lobe compressor and the motor, a protective cover of a coupling is needed not to be arranged.

Description

[0001] technical field [0002] After retrieval, the present invention relates to the category of F25B refrigerator, refrigeration equipment or system on the International Patent Classification (IPC), especially belongs to the servo adapter connecting the screw compressor and the motor. Background technique [0003] The screw compressor works by the high-speed rotation of the motor to drive the rotation of the screw to compress the refrigerant. The rotation shaft of the motor and the rotation shaft of the compressor are connected by a coupling. Due to the high speed, the deviation of the coaxiality of the two shafts is small. The existing way to adjust the coaxiality is generally to find the coaxiality through thin adjusting shims, which is difficult to work and takes a long time. Moreover, most of the couplings of existing motors and screw compressors are exposed to the outside, and a special protective cover needs to be designed for protection to prevent safety acciden...

Problems solved by technology

The existing way to adjust the coaxiality is generally to find the coaxiality through thin adjusting shims. Using this method is difficult and takes a long time

Moreover, most of the couplings of existing motors and screw compressors are exposed to the outside, and a special protective cover needs to be designed for protection to prevent safety accidents caused by the falling of bolts and nuts during high-speed rotation of the coupling, so there are potential safety hazards in use.
