JP2000158023A - Case for low rotation chain coupling - Google Patents

Abstract

PROBLEM TO BE SOLVED: To extremely simply attach and detach a cover by arranging a hinge on one side of the main body of a case and a spring clamp on the other side. SOLUTION: The case is used for protecting a chain coupling of a rotary shaft for adjusting roll positions of a sinking mill from dust and roll cooling water during rolling and for prolonging its life. The hinge 9 is provided on one side of the main body 6 of this case and the spring clamp 8 is arranged on the other side. In such constitution, the coupling parts are connected by hooking the spring clamp 8 on the hinge 9 and, on the contrary, when the connected part is separated, by upward lifting the handle 10 of the spring clamp 8, the clamp is disengaged from the hinge 9 and the connected part is separated. In this way, the case can be detached without removing bolts whenever by small labor in short time. When the shafts connected with the coupling is rotated at high speed, because there is possibility that the elongation of the sprig caused by the centrifugal force of rotation is generated and the clamp is disengaged, this clamp is applied to the coupling for low rotation.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-speed chain coupling case.

[0002]

2. Description of the Related Art Generally, a sinking mill has a structure as shown in FIG. That is, FIG. 2 is a sectional view showing the structure of the sinking mill. FIG. 2A is a front sectional view, and FIG. 2B is a transverse sectional view. As shown in FIG. 2, two rolls are provided in a housing by a two-roll strand type sizer, and the chocks 4 are suspended in the vertical direction of the rolls and the vertical adjustment performed on the roll axis. This is carried out with the screw 2 that holds down the tension bolt 1 and the chock 4. Screw 2
Is turned with a wrench or the like.

At this time, in order to adjust the roll axis horizontally, it is necessary to disconnect the chain coupling 5 once and move only one roll screw. This chain coupling 5 is used to connect two rotating shafts,
A chain coupling 5 in which a two-row roller chain is wound around two sprockets is protected from dust and roll cooling water during rolling, and the case used to extend the life of the chain coupling is made easier to use. There is a need.

[0004]

FIG. 3 is a sectional view of a conventional chain coupling case. Conventionally, as shown in FIG. 3, this case for a chain coupling has a split shape which can be divided in a direction perpendicular to the shaft, and is secured by bolts 7 so that the cover does not come off during rotation. It is actually bolted.
Such a conventional case for a chain coupling is designed to prevent the lubricant from scattering at the time of high rotation. Therefore, four or more bolts are fixed to prevent the cover from coming off during rotation. However, since the chain coupling for adjusting the roll position of the rolling mill is frequently adjusted, it is necessary to take out the cover each time, disassemble and connect the chain, and it is very troublesome to attach and detach the cover. is there.

Means for Solving the Problems In order to solve the above-mentioned problems, the inventors have intensively developed and as a result, a hinge has been attached to one side and a spring has been attached to the other side so that the cover can be attached and detached very easily. An object of the present invention is to provide a low-rotation chain coupling case provided with a type of clasp. The gist of the invention is that in a case for a low-speed chain coupling, a hinge for one side of the case body and a spring-type clasp are provided on the other side of the case for a low-speed chain coupling. In the case.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is a sectional view of a low-rotation chain coupling case according to the present invention. As described above with reference to FIG. 2, the sinking mill is a two-roll strand type sizer, in which two rolls are disposed in a housing, and the chocks 4 are suspended in the vertical direction of the rolls and in the vertical direction of the roll axis. Screw 2 holding down tension bolt 1 and chock 4
Do with. In order to rotate the screw 3, the screw 3 for adjusting the screw is turned with a wrench or the like. At this time,
In order to adjust the roll axis horizontally, it is necessary to disconnect the chain coupling 5 once and move only one roll screw.

The present invention is a case in which this chain coupling 5 is used for protecting the chain coupling 5 from dust and rolling cooling water during rolling and extending the life of the chain coupling. is there. FIG. 1 (a)
FIG. 1 is a top view of a low-rotation chain coupling case according to the present invention, and FIG. As shown in FIG. 1, a hinge 9 is provided on one side of the case main body 6, and a spring type clasp 8 is provided on the other side. With such a configuration, the spring-type clasp 8 is hooked on the hinge 9 to connect the coupling part, and when the coupling part is separated, the handle 10 of the spring-clasp 8 is lifted upward and removed from the hinge 9. To separate.

However, if the shaft to which the coupling is connected rotates at a high speed, the spring may be extended due to the centrifugal force of the rotation, and may be detached from the cover. Therefore, in the present invention, in particular, for low rotation such as for adjustment, for example, for a rotating shaft chain coupling for roll position adjustment of a sinking mill, or for a rotating shaft chain coupling for roll position adjustment of a Transvaleron gator mill And so on.

[0009]

As described above, the present invention has an extremely simple and remarkable effect that makes it possible to remove the case in a short time with a small amount of labor without removing the individual bolts as in the prior art.
