Its further technological scheme is:
Periphery returning apparatus the second connecting sleeve that is positioned at described main shaft, described the second connecting sleeve is connected with cylinder;
The periphery of described belt pulley end is clamping locking nut also;
The a pair of deep groove ball bearing that described clutch shaft bearing group is adjacent layout, installs clutch shaft bearing spacer ring between the deep groove ball bearing of each adjacent layout.
Two teams' pairing bearing that described the second bearing pack is adjacent layout, installs the second bearing spacer between the pairing bearing of each adjacent layout;
On described front cover, have the first groove, on the bearing cap connecting with described front cover, also have the second groove, boss part and groove part;
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, easy for installation, by air cooling integral tube device is inner at main shaft, effectively realized air cooling and the water-cooled of workpiece in course of working, air cooling simultaneously and water-cooled are carried out from inside workpiece, greatly improve the accuracy of workpiece in course of working, avoided the problem of the accurate difference that workpiece causes by external equipment air cooling, water-cooled in the past; Simultaneously by bearing cap, front cover and waterproof cover are rabbeted each other, and by increasing " O " shape seal ring, effectively realized the present invention's waterproof and dustproof performance from inside to outside.By increasing by two pairs of pairing bearings, and respectively match the back-to-back contact of being installed as of bearing, making, outside the center line of load center in each bearing, has greatly increased and has been subject to loading capability, and improved axial runout, and axle is beated guarantees to be 2～4um.
