By using above-mentioned technical proposal, cylinder roller bearing is as the rear support of main shaft, the axle at main shaft adjacent two
Between shoulder, by the shaft shoulder at two respectively to sleeve, the position-limiting action of circlip for shaft, cylinder roller bearing is limited indirectly
Position.
It is preferred that, the main shaft other end is additionally provided with the second flanged type bearing (ball) cover, and the second flanged type bearing (ball) cover is located at casing
Outside, the face that the second flanged type bearing (ball) cover is contacted with main shaft, which is provided with annular groove, annular groove, is provided with felt collar oil sealing.
By using above-mentioned technical proposal, the sealing of main shaft and the second flanged type bearing (ball) cover junction can be further enhanced
Property, with good oil-leakage-prevention effect.
It is preferred that, sleeve two, straight spur gear are additionally provided with main shaft, straight spur gear is connected with main shaft by key,
Sleeve two is located between straight spur gear and briquetting locking nut, and straight spur gear is provided with relative to the opposite side of sleeve two
Second circlip for shaft.
By using above-mentioned technical proposal, straight spur gear can be made to be fixed well with main shaft, keep stable drive.
In summary, the utility model has the advantages that：
Main shaft bearing has higher running accuracy, and main shaft can bear larger radial load, axial load, also with good
Waterproof well, oil-leakage-prevention sealing.
