Description
Technical field
Equipment for building materiaIs manufacturing.
Background technology
The Φ above tube mill of 3.8m diameter of existing use on market all uses slide shoe bearing, Figure of description 1: be transformation
Front tube mill rotating part, in figure, 1 is the rotating cylinder of transformation front tube mill two ends band boss axle, and 2 is crawler shoe bearing portion before transformation,
It is arranged on the position of transformation front tube mill rotating cylinder two ends band boss axle, turns round in order to support existing tube mill rotating cylinder
Motion, 3 is transformation fore bearing sole plate, and slide shoe bearing portion is sitting on bearing sole plate, is transformation fore bearing by 13
Seat fastens with sole plate connecting bolt, and transformation fore bearing sole plate is that the front sole plate of transformation is solid with basis by 14
Fixed is bolted on concrete foundation, and structure such as Figure of description 2 Fig. 3 of crawler shoe bearing portion before transformation, in figure, 6 is to change
Making the boss axle at front tube mill rotating cylinder two ends, 4 is crawler shoe jewel (babbitt metal bearing body) before transformation, grinding machine normal rotation
Time support rim axle rotate, slide shoe bearing lining is that face contact with boss axle, and centre has lubricating oil to do to lubricate generation sliding friction, change
Making front crawler shoe jewel and being sitting in 5 is before transformation on crawler shoe bearing block, and 5 be that crawler shoe bearing block is sitting in 3 before transformation is transformation fore bearing
Sole plate, forms the basic structure in slide shoe bearing portion, and Φ 3.8m diameter above tube mill rotating cylinder is built with liner plate, grinding
Body and material, its weight is more than 500 tons, and the diameter of its bearing of slide shoe bearing is more than the barrel diameter of tube mill, its bearing portion
The boss axle divided is to process after thickening is directly strengthened at two ends based on cylinder, such as φ 4.2m × 13m tube mill
Through 4.2m in cylinder.So its bearing is at the two ends of cylinder, and the external diameter of its boss axle is more than φ 4.4m, on the internal diameter of jewel
It is also required to more than 4.4m.Due to being relatively large in diameter of bearing, then the linear velocity produced when cylinder normally works and rotates continuously is just
Comparatively fast, the frictional resistance moment that therefore grinding machine rotating cylinder is to be overcome when rotating is also big, compares employing rolling bearing and consumes motor
Power draw want many.Power consumption is the highest, have impact on the performance of the effective power draw of motor, has very much necessity of improvement.
Summary of the invention
The Φ 3.8m diameter former slide shoe bearing of above tube mill of existing use on market uses rolling bearing instead, Fig. 4: be to change
Rolling bearing tube mill revolving drum body after making, in figure, 1 is the rotating cylinder of primary tube grinding machine two ends band boss axle, and 17 is to change
Axis of rolling bearing portion after making, is arranged on the position of primary tube grinding machine rotating cylinder two ends band boss axle, returns in order to support tube mill
Drum body does gyration, and 3 is original parts bearing sole plate, and axis of rolling bearing portion is sitting on bearing sole plate.Roll
Bearing portion and bearing sole plate are that bearing block fastens with sole plate connecting bolt by 13, and bearing sole plate passes through
14 to be sole plate fixing with basis is bolted on concrete foundation, and in Fig. 4,17 is improved axis of rolling bearing portion,
Fig. 5 Fig. 6 is the assembling unit structure figure of axis of rolling bearing portion, and in figure, 6 is the boss that make use of the front tube mill rotating cylinder two ends of transformation
Axle, 7 is gripping sleeve group, and gripping sleeve one group is two circles, and axial is bolt tension with 18, and tight boss axle and 8 is rolling bearing
Inner ring, 9 is biserial rolling element, and 10 is that to be sitting in 16 be on rolling bearing pedestal to bearing lower branch, forms the basic knot of rolling bearing
Structure, the biserial rolling element of rolling bearing is that rolling wire contacts with rolling bearing inside race and bearing lower branch, and coefficient of friction is 0,
0025, to reduce 16 times than slide shoe bearing coefficient of friction 0.04, slide shoe bearing to consume the power driving motor about 12%, rolling
Dynamic bearing only consumes the power driving motor about 1%, and the technological transformation therefore using rolling bearing replacement slide shoe bearing can be real
Now save energy and reduce the cost, Fig. 6: be Fig. 5 D-D sectional view, it is possible to understand the section shape of axis of rolling bearing portion parts.These parts constitute sliding
Carry out all installations scheme that bearing is transformed to rolling bearing.Realize slide shoe bearing and use the good transition of rolling bearing instead.

Tube mill rotating cylinder does gyration, and 3 is original parts bearing sole plate, axis of rolling bearing portion be sitting in bearing sole plate it
On.Axis of rolling bearing portion and bearing sole plate are that bearing block fastens with sole plate connecting bolt by 13, bearing basis
Base is sole plate and fixing being bolted on concrete foundation in basis by 14.
In Fig. 4,17 is improved axis of rolling bearing portion, and Fig. 5 Fig. 6 is the assembling unit structure figure of axis of rolling bearing portion, and in figure, 6 are
Make use of the boss axle at the front tube mill rotating cylinder two ends of transformation, 7 is gripping sleeve group, and gripping sleeve one group is two circles, axially uses
18 is bolt tension, and tight boss axle and 8 is rolling bearing inner ring, and 9 is biserial rolling element, and 10 is that bearing lower branch is sitting in 16
It is on rolling bearing pedestal, forms the basic structure of rolling bearing, the biserial rolling element of rolling bearing and rolling bearing inside race
Being that rolling wire contacts with bearing lower branch, coefficient of friction is 0,0025, to reduce 16 times than slide shoe bearing coefficient of friction 0.04, sliding
Carrying out bearing and to consume the power driving motor about 12%, rolling bearing only consumes the power driving motor about 1%, therefore uses
Rolling bearing replaces the technological transformation of slide shoe bearing to be capable of saving energy and reduce the cost.Fig. 6: be Fig. 5 D-D sectional view, it is possible to understand rolling
The section shape of moving axis bearing portion parts.These parts constitute all installations scheme that slide shoe bearing is transformed to rolling bearing.Realize
Slide shoe bearing uses the good transition of rolling bearing instead.
