Abstract
The utility model discloses a bearing device of support roll neck of continuous casting and rolling mill, which comprises a columnar roller bearing (1) and a rotary support (2), which are arranged on a roll neck (3) side by side, are fastened at both sides by two press covers (6) and connected with a bearing housing (4) at the upper end; the press covers are fixed on the bearing housing through screws (5); the inner ring of the columnar roller bearing (1) is tightly matched with the roll neck (3); the rotary bearing (2) is in clearance fit with the roll neck (3) and the bearing housing (4); and the inner ring of the rotary bearing (2) is pressed by a fastening nut (7), a fastening screw (8) and an opening fastening sleeve. The bearing device has the advantages of easy installation and detachment, improved product accuracy and prolonged service life.
Description
Technical field
The utility model belongs to technical field of bearings, especially relates to the bearing arrangement that a kind of continuous casting and continuous rolling mill supports roll neck.
Background technology
At present, generally use four row conical bearings to support roll neck in continuous casting and continuous rolling mill, exposed problems mainly contains: 1, taper roll bearing internal diameter and roll neck are matched in clearance, easily produce wriggling in the course of work, damage axle and bearing, directly influence the geometric accuracy of the plate face of processing simultaneously; 2, taper roll bearing play adjusting process complexity, and accuracy is difficult to guarantee.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides the bearing arrangement that a kind of continuous casting and continuous rolling mill supports roll neck, and it can simplify mounting process, improves the product precision, increases the service life.
For achieving the above object, the utility model adopts following technical scheme:
Described continuous casting and continuous rolling mill supports the bearing arrangement of roll neck, it comprises a cylinder roller bearing and single-revolution supporting, and cylinder roller bearing and pivoting support are installed on the roll neck side by side, and both sides are fastening by two glands, the upper end is connected with bearing housing, and gland is fixed on the bearing housing by screw; Cylinder roller bearing inner ring and roll neck closely cooperate, and pivoting support and roll neck and bearing housing matched in clearance are by locking nut, lock screw, the tight pivoting support inner ring of opening locking casing pressure.
Described continuous casting and continuous rolling mill supports the bearing arrangement of roll neck, and that its cylinder roller bearing can adopt is single-row, biserial, multiple row cylinder roller bearing or full-complement cylinder roller bearing.
Described continuous casting and continuous rolling mill supports the bearing arrangement of roll neck, and its pivoting support can adopt the four-point contact ball of contact angle between 25 °～45 °.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
1, cylinder roller bearing simple in structure, be easy to guarantee self machining accuracy, thereby improve the product precision;
2, cylinder roller bearing long service life is compared with unidimensional taper roll bearing, and can improve 80% the fatigue life of bearing;
3, cylinder roller bearing internal diameter and roll neck closely cooperate, and the wriggling that can eliminate in the operation process damages, and are benchmark grainding rolls faces with the inner ring raceway face simultaneously, have improved the precision and the surface quality of products of roll;
4, cylinder roller bearing is easily installed, is dismantled;
5, pivoting support can bear the axial force that produces in the course of work.
Description of drawings
Fig. 1 is the assembly structure figure that continuous casting and continuous rolling mill supports the bearing arrangement of roll neck;
Among the figure: the 1-cylinder roller bearing; The 2-pivoting support; The 3-roll neck; The 4-bearing housing; The 5-screw; The 6-gland; The 7-locking nut; The 8-lock screw; 9-opening lock sleeve.
The specific embodiment
As shown in fig. 1: this continuous casting and continuous rolling mill supports the bearing arrangement of roll neck, it comprises a cylinder roller bearing (1) and single-revolution supporting (2), cylinder roller bearing and pivoting support are installed on the roll neck (3) side by side, both sides are fastening by two glands (6), the upper end is connected with bearing housing (4), and gland (6) is fixed on the bearing housing (4) by screw (5); Cylinder roller bearing (1) inner ring and roll neck (3) closely cooperate, and pivoting support (2) and roll neck (3) and bearing housing (4) matched in clearance compress pivoting support (2) inner ring by locking nut (7), lock screw (8), opening lock sleeve (9).
Described continuous casting and continuous rolling mill supports the bearing arrangement of roll neck, and that its cylinder roller bearing can adopt is single-row, biserial, multiple row cylinder roller bearing or full-complement cylinder roller bearing.
Described continuous casting and continuous rolling mill supports the bearing arrangement of roll neck, and its pivoting support can adopt the four-point contact ball of contact angle between 25 °～45 °.
At first inner ring and the roll neck (3) with cylinder roller bearing (1) carries out hot charging, and both closely cooperate; Outer assembly and pivoting support (2) with cylinder roller bearing (1) is installed in the bearing housing (4) side by side then, and both sides are fastening by two glands (6) and screw (5), form a whole; Then above-mentioned integral part is installed on the roll neck (3), compresses pivoting support (2) inner ring by locking nut (7), lock screw (8), opening lock sleeve (9) successively again, finish the whole erection process.Bear radial effect power by cylinder roller bearing in the course of work, pivoting support bears axial force.
Wherein also take matched in clearance between opening lock sleeve (9) and the axle, can regulate lock screw to the axial thrust of pivoting support (2) inner ring by lock screw (8) and the relative rotation between the opening lock sleeve (9).
In use, roll crown will carry out weekly grinding, and roll neck during grinding (3) need not separate with cylinder roller bearing (1) inner ring, is that benchmark grinds with cylinder roller bearing (1) inner ring raceway face directly, comparing with the roll neck is that benchmark grinds, and precision can improve more than 3 times; Because cylinder roller bearing (1) inner ring has the assembling chamfering of being convenient to install, between interior fourth contact of cylinder roller bearing (1) and the interior roller surface 0.3～0.4mm gap is arranged during installation in addition, make installation process easy, quick.
Claims (3)
