Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly aims at reducing the bias of the running fabric when running a long fabric such as woven fabric, film, or paper and performing various treatments such as dyeing, drying, and winding. The present invention relates to improvements in bearing members for rotating rolls, such as guide rolls for correcting deviation, which are installed in the travel path of the rolls in order to prevent or correct damage such as positioning.

By the way, the above-mentioned rotating roll has a rotary opening roll because it is necessary to perform a deviation correcting action or a guiding action on the running fabric even when the running fabric deviates left and right in the running direction. It is customary to form the roll to be longer than the horizontal width of the dough, and to rotatably support both ends of the roll using bearing members.

However, when forming a long rotating roll as described above, conventionally, as shown in FIG. Since the outer circumferential surface C' of the bearing member C is tightly fitted to the inner circumferential surface B', the wall thickness of the large-diameter inner circumferential surface B' portion, that is, the bearing member fitting portion is thinner, and the fitting is made tighter. Not only is there an unfavorable strength problem in the bearing part, but also because the roll is a long body and it is necessary to align the roll and the bearing member during the cutting process, it is necessary to use a dedicated or large-sized roll. There were drawbacks such as the need for cutting equipment.

This invention can be applied to the inner circumferential surfaces of both ends of a raw tube for rotating rolls (pipe body before processing without cutting) without cutting the inner circumferential surfaces of both ends of the rotating rolls as described above. The present invention relates to an improvement in a bearing member configured to be able to be attached or detached at will.

This will be explained below with reference to the embodiments shown in FIGS. 2 to 6.

Reference numeral 1 denotes a rotating roll for correcting or guiding the running material A, and the roll is formed of a raw pipe cut into a long body.

Reference numeral 2 denotes bearing members fitted onto the inner circumferential surface 1a at both ends of the rotating roll 1, and the bearing members are fitted onto a shaft 4 appropriately supported between the arms 3 on the sides of both ends of the rotating roll 1. Therefore, the roll 1 is rotatably provided on the shaft.

However, the bearing member 2 is formed so that the outer diameter of its main body 5 is slightly smaller than the inner diameter of the rotary roll (raw pipe) 1, so that it can be easily attached to and detached from the inner circumferential surface of both ends of the roll under normal conditions. It is considered possible.

Further, a plurality of through holes 6 extending in the axial direction (the longitudinal direction of the roll 1 or the shaft 4) are bored at equal intervals on the same circumference on the outer circumferential side of the main body 5, and these through holes include the following: A tapered surface 9 is formed that widens from the outer end opening 7 side, which has a smaller diameter, toward the inner end opening 8, which has a larger diameter.

Reference numeral 10 denotes a linear slit in the axial direction passing approximately through the center of each of the through holes 6, and the slit has an appropriate diameter line x-x passing through the center of the through hole 6 and the center of the bearing member main body 5. A notch is formed in a direction having an angular inclination.

11 is a tapered pin having a tapered surface 12 corresponding to the shape of the tapered surface 9 in each through hole 6 of the bearing member;
A suitable threaded portion 13 is attached to the tip of the pin on the small diameter shaft side.
is formed, and when the threaded portion is inserted from the large-diameter opening 8 side of the through hole toward the small-diameter opening 7 side, the tip thereof can protrude from the small-diameter opening 7. It has a certain length.

Numeral 14 is a nut to be screwed onto the threaded portion 13 of the taper pin, and one end of this nut is fitted with the threaded portion 1 of the pin.
A screw hole 15 into which the nut can be screwed is formed, and an engagement hole 16 such as a hexagonal hole into which a rotating tool of the nut can be engaged is formed at the other end.

Reference numeral 17 denotes a gap created between the inner circumferential surface 1a of the rotating roll and the outer circumferential surface 53 of the bearing member main body 5, and 18 denotes a sealing member fitted to the inner circumferential surface of both ends of the roll 1, which also serves as an end treatment member for the roll. be.

As shown in FIG. 6, in the vicinity of the slit 10 on the outer circumferential surface 5a of the bearing member main body described above, a large number of latching protrusions 19 are provided by knurling or the like, and the protrusions are attached to the inner circumferential surface 1a of the rotating roll. It may be configured such that the locking effect of both is improved by biting into the ring.

Moreover, although the case where the above-mentioned slit 10 is formed by a linear notch passing through the through hole 6 is shown, this notch may be formed up to the through hole 6. The slit may be formed in the horizontal direction with respect to the through hole 6 from the outer peripheral surface 5a side of the member main body.
It is sufficient if it is formed all the way to the sides.

In addition, each through hole 6 and each taper pin 11 of the member main body are
The above shows the case where each shape is circular in cross section.
In order to prevent the taper pin 11 from rotating within the through hole 6, both may be formed to have a rectangular cross section.

In the bearing member of the present invention having the above configuration, each taper pin 11 is normally connected to each through hole 6 of the member main body, as shown in FIG.
The tip of the threaded portion 13 protrudes from the small diameter opening 7 of the hole, and the nut 1 is inserted into the protruding threaded portion 13.
4 is screwed, but when this bearing member is fitted and latched into the roll inner circumferential surface 1a, as shown in the figure, With the threaded nut 14 side facing toward the end surface of the roll 1, the screw nut 14 is inserted to a desired position on the inner circumferential surface of the end of the roll.

Next, when each nut 14 is rotated using a suitable rotating tool, the taper pin 11 tries to rotate with the nut 14 at the initial stage, but the taper surface of the pin
2 and the tapered surface 9 in the through hole of the member body are brought into pressure-sliding contact, the taper pin 11 moves toward the end surface side of the roll 1.

Therefore, due to the wedge effect caused by this movement, the slit 1
The outer peripheral hooking surface portion 20 on the side opposite to the center of the member main body at 0 is
As shown by the chain line in FIG. 5, the inner peripheral surface 1a of the roll
It is curved and deformed to the side and is crimped onto the inner circumferential surface, and at this time, the taper pin 1 described above is
For example, by setting the rotational torque of each nut 14 in advance to be approximately constant by appropriate means so that the moving distances of the nuts 14 and 1 are equal, each locking surface portion 2 is
Since the curvature deformation of 0 can be made substantially constant, the bearing member 2
The center alignment between the roller 1 and the roll 1 can be easily performed.

The movement of the pin 11 can be adjusted arbitrarily and individually by turning a nut 14 screwed onto the husband.

As described above, the bearing member of the present invention has a shaft having a tapered surface at a circumferential position on the outer circumferential side of the member main body that widens from the small-diameter opening side at one end toward the large-diameter opening side at the other end. drilling a plurality of through holes in the same direction, and fitting each of the through holes with a taper pin having a threaded portion at the tip and a tapered surface corresponding to the shape of the tapered surface of the hole,
Furthermore, nuts for adjusting the movement of the pin in the axial direction are screwed into the threaded portions of the taper pin, and further, nuts for adjusting the movement of the pin in the axial direction are screwed into each of the through holes. Since the structure is such that appropriate slits are formed in each part, it is not only extremely easy to attach and detach the member body to the inner circumferential surface of the end of the rotating roll, but also eliminates the need for cutting the inner circumferential surface of the end of the roll. Therefore, the raw tube can be used as it is for the roll body, and there is no damage to the strength of the fitting part of the bearing member, and this type of rotating roll is easy to manufacture and the product is inexpensive. It has the following effects:
