Description
Technical field
The present invention relates to dry type rod mill, specifically a kind of dry type rod mill thermally expands servo-actuated bearing group.
Background technique
Existing rod mill can generate very high temperature in steel slag production process, and cylinder can be produced due to thermal expansion and contraction principle
Raw axial float, increases the abrasion between cylinder and bearing, watt shell, so that the service life of rod milling machine drum body, watt shell, bearing
It substantially reduces.
Summary of the invention
Present invention seek to address that the above problem, so that providing one kind can be swollen with the dry type rod mill heat of cylinder axial displacement
Swollen servo-actuated bearing group.
The present invention solves described problem, the technical solution adopted is that:
A kind of servo-actuated bearing group of dry type rod mill thermal expansion, including bearing block, pedestal, are provided with roller bearing between bearing block and pedestal
Group, bearing block can be moved axially by roller groups with cylinder.
The present invention by adopting the above technical scheme, compared with prior art, the feature protruded is:
It realizes that bearing group can generate when the temperature is excessively high axial displacement in process of production with cylinder by roller groups, reduces cylinder
Hollow shaft and bearing, bearing and pedestal cap between friction, substantially increase cylinder, bearing and bearing assembly use the longevity
Life, reduces maintenance frequency, saves maintenance cost, improve production efficiency, reduce production cost.
Preferably, the further technical solution of the present invention is:
Roller groups include several rolling bars and the connecting plate for being placed in rolling bar both ends, and the both ends of rolling bar are set in connecting plate, and connecting plate will be several
Rolling bar connection in a row constitutes roller groups, and bearing block is moved axially on pedestal with cylinder in cylinder axial float by rolling bar.
On the bottom surface of bearing block and it is respectively arranged with corresponding groove on the upper surface of pedestal, is provided with and sets on rolling bar
In the boss in lower notches, prevent rolling bar from generating radial displacement in moving process.
The first pressing plate, the two sides of the axial direction of bearing block are respectively arranged on the two sides of the radial direction of bearing block
On be respectively arranged with the second pressing plate, be separately provided between the first pressing plate and bearing block, between the second pressing plate and bearing block
The sealing felt of roller groups is sealed, felt is sealed by the first pressing plate and the second pressing plate and is fixed on bearing block surrounding, by roller groups
It seals, so that roller groups have reached good leakproofness.
First pressing plate and the second pressing plate are mounted by means of bolts on bearing block respectively.

Specific embodiment:
Below with reference to embodiment, the invention will be further described, and purpose, which is only that, more fully understands the content of present invention, therefore, institute
The example of act is not intended to limit protection scope of the present invention.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of servo-actuated bearing group of dry type rod mill thermal expansion, including bearing block 1, pedestal 7, bearing
Roller groups are provided between seat 1 and pedestal 7, bearing block 1 can be moved axially by roller groups with cylinder 10.
Roller groups include several rolling bars 4 and the connecting plate 6 for being placed in 4 both ends of rolling bar, and the both ends of rolling bar 4 are set in connecting plate 6, even
Plate 6, which connects several rolling bars 4, in a row constitutes roller groups, and bearing block 1 is in 10 axial float of cylinder through rolling bar 4 on pedestal 7
It is moved axially with cylinder 10.
On the bottom surface of bearing block 1 and it is respectively arranged with corresponding groove 9 on the upper surface of pedestal 7, is arranged on rolling bar 4
There is the boss 8 being placed in lower notches 9, prevents rolling bar 4 from generating radial displacement in moving process.
It is respectively arranged with the first pressing plate 2 on the two sides of the radial direction of bearing block 1, the two of the axial direction of bearing block 1
It is respectively arranged with the second pressing plate 5 on side, is set respectively between the first pressing plate 2 and bearing block 1, between the second pressing plate 5 and bearing block 1
It is equipped with the sealing felt 3 for sealing roller groups, sealing felt 3 is fixed on bearing block 1 by the first pressing plate 2 and the second pressing plate 5
Surrounding side on, roller groups are sealed, so that roller groups have reached good leakproofness.
First pressing plate 2 and the second pressing plate 5 are mounted by means of bolts on respectively on bearing block 1.
The present invention realizes that bearing group can generate when the temperature is excessively high axially in process of production with cylinder 10 by roller groups
Displacement reduces the friction between the hollow shaft and bearing, bearing and pedestal cap of cylinder 10, substantially increases cylinder 10, bearing
And the service life of bearing assembly, maintenance frequency is reduced, maintenance cost is saved, improves production efficiency, reduces production
Cost improves the reliability of equipment.
The foregoing is merely preferably feasible embodiment of the invention, not thereby limiting the scope of the invention,
It is all to use equivalence changes made by description of the invention and its accompanying drawing content, it is intended to be included within the scope of the present invention.
