This rotor compressor's motor stator is fixed on last cylinder cover, makes casing and motor stator break away from the rigid contact, leaves the clearance between motor stator and the casing simultaneously, and motor stator can not receive the casing influence and produce deformation or displacement, avoids appearing the bad scheduling problem of motor air gap. Can easily dismantle motor stator and last cylinder cover simultaneously, solve the bad scheduling problem of air gap through the position of adjusting motor stator.
Description
Technical Field
The utility model relates to a rotor compressor with a motor connecting structure, and belongs to the technical field of compressors.
Background
The compressor is a fluid machine for lifting low-pressure gas into high-pressure gas, is a heart of a refrigeration system, sucks low-temperature low-pressure refrigerant gas from an air suction pipe, utilizes a motor to operate and drive a piston to compress the low-temperature low-pressure refrigerant gas, and then discharges the high-temperature high-pressure refrigerant gas to an exhaust pipe, thereby providing power for a refrigeration cycle.
At present, a motor rotor is directly fixed on a shell of a rotor compressor usually in a fixing mode of welding or shrink fit, if the problems of poor air gap and the like are generated between the motor rotor and a motor stator, the position between the shrink fit or welded motor stator and the rotor cannot be adjusted, and therefore the motor and the whole rotor compressor are easily scrapped. Meanwhile, the problems of poor air gap and the like of the motor are easily caused by the deformation of the shell generated by welding and hot sleeve.
Disclosure of Invention
In order to solve the technical problems in the prior art, the utility model provides the rotor compressor with the motor connecting structure, which is not easy to generate poor air gaps and is easy to adjust the air gaps between the motor rotor and the motor stator.
The technical scheme for achieving the purpose of the utility model is that the rotor compressor with the motor connecting structure at least comprises an upper cylinder cover, a motor stator and a shell, wherein a gap is reserved between the motor stator and the shell, the upper cylinder cover is provided with at least 2 bulges protruding out of the outer surface, the distance between every two adjacent bulges is equal, the bulges are provided with counter bores, and the motor stator is provided with through holes matched with the counter bores.
The technical scheme is further improved as follows: the counter bore is a threaded hole.
The through hole is a unthreaded hole.
The protrusion and the motor stator are connected through a screw.
The protrusion is a cylinder.
The protrusion is in contact with the motor stator.
The upper cylinder cover and the bulge are substantially integrated.
According to the technical scheme, the method comprises the following steps: (1) the motor stator of the rotor compressor with the motor connecting structure is fixed on the upper cylinder cover, so that the shell and the motor stator are separated from rigid contact, and meanwhile, a gap is reserved between the motor stator and the shell, so that the motor stator cannot be deformed or displaced due to the influence of the shell, and the problems of poor air gap of the motor and the like are avoided.
(2) The motor stator of the rotor compressor with the motor connecting structure is connected with the upper cylinder cover through the screw, so that the motor stator and the upper cylinder cover can be easily disassembled, and the problems of poor air gap and the like are solved by adjusting the position of the motor stator.
