Abstract
The utility model relates to a mechanical device, more specifically, a bearing block device for a non-transmitting straightening roll. The utility model is characterized in that the bearing block device for a non-transmitting straightening roll comprises at least a working roll, a roll sleeve, bearings, distance rings, a spring, a backing ring, a blocking ring and an inner shaft, wherein the working roll (1) is integrally connected with the roll sleeve (2) which is fixed on the angular contact bearing (3) by a pair of distance rings (4) arranged on the inner shaft (11), the back section of the inner shaft (11) is spaced and fixed with the bearing (8) by an inner sleeve (5), the outer end of the bearing (8) is fixed with the blocking ring (10) by a through cover (9), and the spring (6) is pressed and butted on the inner ring of the bearing (8) by the backing ring (7). The bearing block device for a non-transmitting straightening roll has the advantage of compact performance of placement of narrow space and large force energy, and is used for the structural form of the shaft end of the working roll of a continuous bend-stretching straightening machine.
Description
Technical field
The utility model relates to a kind of mechanical device, more specifically to be not transmission straightening roller bearing holder device.
Background technique
When the big specification band steel of aligning, straightening roller will bear very big radial and axial load, this just requires a kind of existing compactedness that can lay at small space, has bigger power energy again, the structure that can also satisfy the high speed requirement that production scale increase face is caused occurs, and present equipment can't round Realization.Common structure adopts thrust bearing to bear axial force, and with this bearing fixing circle of pressure spring clamping, Location accuracy is very poor, is difficult for installing.
Summary of the invention
The purpose of this utility model provides a kind of not transmission straightening roller bearing holder device, and its existing compactedness that can lay at small space has bigger power energy again, is used for the axle head structural type of continuously elongated bending straightening machine work roll.
The technical solution of the utility model is to realize like this, design a kind of not transmission straightening roller bearing holder device, it is characterized in that: which comprises at least work roll, roller shell, bearing, distance ring, spring, gasket ring, back-up ring, interior axle, work roll 1 is coupled as one with roller shell 2, and roller shell 2 is fixed on the angular contact bearing 3 by distance ring 4 by a pair of on the axle 11 in being installed in; Interior axle 11 back segments are fixed with bearing 8 by interior cover 5 spacings, and bearing 8 outer ends are fixed by saturating lid 9 and back-up ring 10; Spring 6 is pressed against by gasket ring 7 and encircles in the bearing 8.
Described work roll slenderness ratio is 50.
Characteristics of the present utility model are: because work roll is its key components and parts, characteristics are that slenderness ratio reaches 50, radial load is big, working speed is high.All the time, can the spindle nose position structure of work roll be its key that normally use of decision.Be the body of roll location during this roller work, two spindle nose bearing supports are used for bearing the suffered axial force of roller, and carry out balance in the off position pair of rollers, and have compact structure, supporting precision height, the axial force that can bear is big, long in the operating mode lower bearing life-span of high rotating speed and big load, and can reduce advantage such as roll breakage.
The utility model is described in further detail below in conjunction with embodiment's accompanying drawing.
Description of drawings
Fig. 1 is not transmission of an embodiment straightening roller bearing holder device structural representation.
Among the figure: 1, work roll; 2, roller shell; 3, bearing; 4, distance ring; 5, interior cover; 6, spring; 7, gasket ring; 8, bearing; 9, saturating lid; 10, back-up ring; 11, interior axle.
Embodiment
As shown in Figure 1, not transmission of embodiment straightening roller bearing holder device adopts the rolling bearing composite structure, assemble as shown in Figure 1: work roll 1 is coupled as one with roller shell 2 becomes solid of rotation, it is the rotating center rotating machinery that roller shell 2 forms with interior axle 11 by a pair of angular contact bearing 3 by distance ring 4 location on the axle 11 in being installed in, pressure spring 6 is used for the yielding gap of angle of equilibrium contact ball bearing 3, spring 6 is pressed against by gasket ring 7 and encircles in the bearing 8, makes to install to become simpler.Interior axle 11 back segments are equipped with bearing 8 by interior cover 5 spacings, and this bearing outer end is fixed by saturating lid 9 and back-up ring 10.Bear axial force with the alternative traditional approach of this axle head mechanism with thrust bearing, can allow that the roller rotating speed improves more than 2 times, and avoided using the shortcoming that thrust bearing can not radial location, made the roller to obtain high supporting precision, and can be applicable to the requirement of high rotating speed, big load; This structure roller shell 2 and body of roll, the integral rigidity height, roller spindle nose stress is not better, and is yielding or fracture.The work roll slenderness ratio is 50, makes that radial load is big, working speed is high.
When the big specification band steel of aligning, straightening roller will bear very big radial and axial load, this just requires a kind of existing compactedness that can lay at small space, has bigger power energy again, the structure that can also satisfy the high speed requirement that production scale increase face is caused occurs, and the utility model designs at above requirement.
Claims (2)
1, not transmission straightening roller bearing holder device, it is characterized in that: which comprises at least work roll, roller shell, bearing, distance ring, spring, gasket ring, back-up ring, interior axle, work roll (1) and roller shell (2) are coupled as one, and roller shell (2) is fixed on the angular contact bearing (3) by distance ring (4) by being installed in a pair of on the interior axle (11); Interior axle (a 11) back segment is fixed with bearing (8) by interior cover (5) spacing, and bearing (8) outer end is fixed by saturating lid (9) and back-up ring (10); Spring (6) is pressed against by gasket ring (7) and encircles in the bearing (8).
2, not transmission straightening roller bearing holder device according to claim 1, it is characterized in that: the work roll slenderness ratio is 50.
