It is an object of the present invention to provide a tension adjusting roller for a wire which is free from contaminants such as dust in a bearing during a rotating plate replacing operation in order to solve the above problems.

The tension adjusting roller of the present invention has a central axis, a bearing fitted on the outer periphery of the axis, and a protrusion with a recess on the inner circumference. The tension adjusting roller is fitted on the outer periphery of the bearing, An inner cover which is fitted to the recess of the protrusion of the lower land portion, a rotating plate which is fitted to the outer periphery of the protrusion of the lower land portion and an upper supporting portion which supports the rotating plate from the upper surface, So that the bearing is not exposed.

The tension roller of this design wire can replace the rotating plate without removing the inner cover, so that when the rotating plate is replaced, the bearing is not exposed. Therefore, the contamination such as dust can not be caught in the bearing, There is an effect that the operation of the post tension regulating roller is not smooth or the tension regulating roller is immediately disassembled again to clean and then reassemble.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The tension adjusting roller of the present invention has a central shaft 41, a bearing 42 fitted to the outer periphery of the shaft 41, and a projection 451 having a concave portion 4511 on the inner peripheral surface, An inner cover 46 which is fitted in the recess 4511 of the protrusion 451 of the lower cover 45 and a lower cover 45 which is fitted to the outer periphery of the lower cover 45, A rotating plate 43 fitted to the outer periphery of the projection 451 of the lower portion ground 45 and an upper land 44 supporting the rotating plate 43 on the upper surface.

The rear end of the shaft 41 is fixed to the fixture to support the bearing 42, the lower portion ground 45, the inner cover 46, the rotary plate 43 and the upper land portion 44. The bearing 42 is fitted on the outer periphery of the shaft 41 and is supported by the lower support 45, the inner cover 46, the rotary plate 43, And rotates together with the site zone 44.

The lower land portion 45 has a protrusion 451 having a concave portion 4511 on an inner circumferential surface thereof and is fitted on the outer periphery of the bearing 42 and supports the rotary plate 43 on the inner circumferential surface and the lower surface of the rotary plate 43. The projecting width of the projecting portion 451 is the same as the width of the rotary plate 43 and the depth of the recess 452 is a depth corresponding to the width of the outer periphery of the inner cover 46.

The inner cover 46 has a recess on the bottom surface and is sized to be fitted in the recess 452 on the inner circumferential surface of the protrusion 451 of the bottom cover 45, And is fastened to the concave portion 4511 of the inner circumferential surface of the projection 451 of the lower land portion 45 with a bolt.

The rotation plate 43 is formed with a hole corresponding to the size of the outer periphery of the protrusion 451 of the lower portion ground 45 and is inserted into the outer periphery of the protrusion 451 of the lower portion ground 45, A plurality of bolt holes are drilled in the upper supporting plate 44 to be fixed to the projecting portions 451 of the lower holding plate 45 with bolts. When the bolt hole of the upper land portion 44 is formed as a long hole and the circumference of one side of the long hole is made larger than the other side, fixing and disassembly of the upper land portion 44 is facilitated.

The rotating plate 43 is made of resin such as rubber or polyurethane or polyethylene and the material of the upper land portion 44, the lower land portion 45 and the inner cover 46 is made of aluminum, aluminum alloy, plastic, Not received.

Next, the assembly and disassembly of the tension adjusting roller of the present invention will be described.

The shaft 41, the bearing 42, the lower cover 45, the inner cover 46, the rotary plate 43, the upper cover 44 and the tightening bolt are separately prepared, and then the shaft 41 The inner cover 46 is fitted into the concave portion 452 of the protruding portion 451 of the lower portion support 45 and the inner cover 46 is fitted into the concave portion 452 of the protruding portion 451 of the lower support portion 45 Fix with bolts. With the provision of the inner cover 46, the front end portions of the bearings 42 and the shafts 41 are covered to be safely protected from contaminants.

Next, the rotary plate 43 is fitted to the outer periphery of the projection 451 of the lower portion ground 45, the upper portion ground 44 is buried on the upper surface of the rotary plate 43, 45 to the protrusions 451. In the case of disassembling the tension adjusting roller assembled as described above, it is necessary to dismantle the above-described assembling step while reversing.

When the rotary plate 43 is to be replaced during use of the tension adjusting roller of the present invention as described above, the bolt fixing the upper land 44 to the projecting portion 451 of the lower land 45 is released and the upper land 44 The rotary plate 43 is pulled out of the protruding portion 451 of the lower edge portion 45 and the new rotary plate 43 is inserted into the outer periphery of the protruding portion 451 of the lower edge portion 45, The upper land portion 44 is buried and then the upper land portion 44 is fixed to the projecting portion 451 of the lower land portion 45 with the bolts.

As described above, the tension adjusting roller of the present invention can replace the rotating plate without detaching the inner cover. Since the bearing is not exposed when the rotating plate is replaced, contaminants such as dust can not be caught in the bearing, The tension adjusting roller may not operate smoothly after the jamming or replacement, or the tension adjusting roller may be disassembled immediately after cleaning and then reassembled.

The present invention can be widely used as a tension adjusting roller for a wire used for cutting a semiconductor, a solar cell, an LED, a laser, etc., a HDD component material, a sapphire, a silicon,
