Son is fixed on the motor shaft；Also include front end flange and bearing block, the front end flange and bearing block are separately fixed at institute
State the both ends of housing；One end of the motor shaft opens up fluted, and the end of the head axle is placed in the groove, the machine
Head axle passes through key connection with motor shaft；The other end of the motor shaft is connected by bearing with the bearing block；The motor shaft
Axially penetrate through and be provided with a bolt, the bolt is connected with the head axle thread and the motor shaft carried out axially solid
It is fixed.
Preferably, the direct-connected motor of the present utility model for compressor also includes the first axle sleeve and rear end cap, institute
State the first axle sleeve to be sleeved on the motor shaft, first axle sleeve and rear end cap are separately positioned on inside and outside the two of the bearing
Side, first axle sleeve and rear end cap are fixedly connected with the bearing block respectively.
Preferably, the motor shaft runs through the rear end cap, and the end of the motor shaft is provided with cooling fan.
Preferably, the direct-connected motor of the present utility model for compressor also includes the second axle sleeve, second axle
It is sleeved on the head axle, described second axle sleeve at least a portion is in the axis hole of the front end flange, and described second
Axle envelope is provided between the axis hole of axle sleeve and the front end flange.
Direct-connected motor of the present utility model for compressor, can be good at solve transmission efficiency it is low, transmission is made an uproar
The problems such as sound is big, and transmission power is limited, and motor axle load is big, and the structure is as a result of the kind of drive being directly connected to, by
Such environmental effects are small, the dust, air humidity etc. in such as air.Direct-connected driving of the present utility model for compressor
Motor, the attachment structure between head axle and motor is enormously simplify, the torque of motor shaft can be directly passed to head axle,
Transmission efficiency is drastically increased, reduces energy loss, reduces noise, compressor stability is further lifted, extended
In the life-span, improve the overall performance of compressor.
