In lid, described bottom surface one and the lower surface of crankcase bodies are flush.
I.e. now, reinforcement is arranged on the junction of crankcase bodies and electric motor end cap, to improve the intensity of junction, from
And improve the overall structural stability of crankcase.
In above-mentioned air compressor crankcase, the upper end of described support ring downwards concave shape into for installing
The step one of oil sealing, the inwall of described connecting cylinder are provided with the step two for being used for installing bearing, and step one and two, step
Put and face.
During actual installation, the bearing in step two is used for positioning motor armature spindle.
Compared with prior art, this air compressor crankcase has advantages below：
1st, crankcase is integrated part, so can effectively reduce manufacturing procedure, so as to effectively improve the convenience of processing, together
When, due to the reduction of manufacturing procedure, equipment investment cost and cost of labor can be both reduced, can be avoided again because process is excessive
The problem of precise decreasing brought, so as to improve the precision of this crankcase, to improve crankcase quality.
The 2nd, support ring and reinforcement are set inside crankcase bodies, connecting cylinder and crankcase bodies are played preferably
Supporting role, to improve the intensity of connecting cylinder and crankcase bodies simultaneously, so as to improve the pressure-bearing of connecting cylinder and crankcase bodies
Ability, to improve the overall structural stability of crankcase, crankcase is set to play consistently support effect, to ensure air pressure
The job stability of contracting machine.
