Description
The utility model relates to a kind of rolling mill roll axial adjusting device, especially medium and small-scale rolling mill roll axial adjusting device.
In the mill milling process, roll easily produces axial displacement, causes rolled piece cross dimensions precision error to occur.Present medium and small-scale rolling mill, short stress path rolling mill particularly, the general roll axial adjusting device of Cai Yonging: the GY type milling train that mainly contains University of Science ﹠ Technology, Beijing adopts bolt type roll axial adjusting device, and it is to drive bearing block roll is moved axially by adjusting positive and negative bolt; Beijing SY of metallurgical equipment research institute type milling train adopts the wounded in the battle valve snail shell type axial adjusting device that is equipped with female locking, and it is by floral disc rotation external thread sleeve, drives thrust bearing, and roll is moved axially in fixing bearing block; The CER-1 type milling train of Beijing Iron﹠Steel Design﹠Research Institute has adopted driving shaft worm to drive turbine eccentric shaft sleeve type axial regulating mechanism.The above two are adjusted, and operation is numerous and diverse, and the time is long, and the short big precision of adjustment power is low, the axial stress line length, and rigidity is low, and it is unreliable to lock, and easily produces play; Latter's adjusting device complex structure is made difficulty is installed, and does not often reach designing requirement in the practical application, is difficult to promote.
The purpose of this utility model provides a kind of rolling mill roll axial adjusting device.It is simple in structure, reliable lock, and axial float is little, and the axial stress line is short, and rigidity is big, and it is easy to adjust that response is fast flexibly, and the precision height can satisfy all kinds of medium and small-scale rolling mill roll mandrels to being adjusted at linearity, accuracy, aspects such as reliability need.
The purpose of this utility model is achieved in that external thread sleeve and bull gear clamp shaft washer, driving pinion drives the bull gear rotation, simultaneously external thread sleeve in the fixed combination nut along screw thread rotation, thrust bearing and roll are moved simultaneously vertically, adjustable shim pack is arranged between the combination nut, the gap that can control fixed combination nut and the axial matching thread of external thread sleeve is enough little, to eliminate the axial float that is produced between screw thread.Alignment pin compresses with helical spring, can make the pinion reliable lock, and it is convenient to break away from.
The advantage of the utility model rolling mill roll axial adjusting device is: the gear drive convenient and flexible operation, and response is fast, adjusts the precision height; The screw thread axial fit clearance is adjustable, and the roll axial float is little, and the axial stress line is short, the rigidity height; The alignment pin reliable lock is not loosening; Apparatus structure is simple, makes and installs easily.
Below in conjunction with accompanying drawing and with embodiment the utility model is described in further detail:
Fig. 1 is the orthogonal view of the utility model rolling mill roll axial adjusting device;
Fig. 2 is the utility model rolling mill roll axial adjusting device left view;
