Milling train is the equipment realizing metal rolled process, the processing of non-ferrous metal wire rod pour cast out blank after need using rolling
Machine rolls to it.But existing milling train is usually present rolling, and intensity is not enough, and transmission speed is slow, fragile, service life
The defect such as short.Additionally, distance between the roll shaft of existing milling train cannot on-line tuning, roller axle base fixes, and adjustment every time is both needed to
Through loaded down with trivial details operation, using being inconvenient.
Utility model content
The purpose of this utility model is: overcomes prior art drawbacks described above, provides a kind of two roller filmatic bearing milling trains.This
Utility model rolling intensity is high, and transmission speed is fast, the distance between roll shaft can on-line tuning, using more convenient.
This utility model is achieved through the following technical solutions:
A kind of two roller filmatic bearing milling trains, includings mill rolls case, be provided with described mill rolls case a pair roller gear shaft with
A pair of ring-type roll, described roller gear axle is respectively driving rollers gear shaft and idle roll gear shaft, described driving rollers
Gear shaft and idle roll gear shaft do not engage each other, both power transmission shaft drive connections with gear-box respectively, and described ring-type is rolled
Roller is fixed on corresponding roller gear axle top by taper expansion set respectively, and described roller gear axle bottom is cased with thrust load rolling
Pearl bearing, described thrust load ball bearing is paired double-row angular contact bal bearing, and described roller gear axle is installed on eccentric bushing
Interior, described eccentric bushing is supported by the filmatic bearing of eccentric bushing and roller gear between centers, and described eccentric bushing is provided with roll gap adjustment silk
Bar.
In this utility model, eccentric bushing is provided with roll gap adjustment screw mandrel, can make two rolls by roll gap adjustment screw mandrel
Gear shaft synchronous backward moves, and ensures that rolling centerline is constant.Ring-type roll support roller gear axle can improve radial load
Ability, thrust load ball bearing selects paired double-row angular contact bal bearing, double-row angular contact bal bearing and single-row angular contact ball
Bearing is compared, and only takes up less axial space, can bear radial load and the axial load acting on both direction, its energy
Limit axle or shell bi-directional axial displacement, contact angle be 30 degree it is provided that the higher Bearing configuration of rigidity, and can bear and topple
Moment, can be obviously improved rolling intensity, improve mill speed.The design of filmatic bearing can effectively extend its test life, reduces
Damage frequency.
As a kind of preferred mode, also include dust cover, described dust cover is arranged at the outside of mill rolls case.By anti-
The design of dust hood, can avoid dust to enter impact service behaviour, ensure the reliable and stable of rolling work.
As a kind of preferred mode, the port of export of described mill rolls case each roll shaft interior is all using neck seal.Pass through
Using neck seal, coolant can be prevented effectively from and enter inside mill rolls case, eliminate the harmful effect that coolant intrusion causes.
This utility model compared with prior art, has advantages below and a beneficial effect:
(1) this utility model rolling intensity is high, and transmission speed is fast, the distance between roll shaft can on-line tuning, using more square
Just;
(2) design by dust cover for this utility model, can avoid dust to enter impact service behaviour, ensure rolling work
Reliable and stable;
(3) this utility model, by adopting neck seal, can be prevented effectively from coolant and enter inside mill rolls case, eliminate cold
