Abstract

PURPOSE:To make the thickness of each hoop of an endless multilayered metal belt uniform and lengthen the lifetime of the hoop, by manufacturing the belt so that the clearance between the adjacent hoops of the belt is substantially zero and by dividing the belt into individual hoops and then chemically polishing them to reduce their thickness. CONSTITUTION:A material 1 for an endless metal belt is formed into a cylinder 1' of small thickness. After the needless ends of the cylinder 1' are cut off, a mandrel is fitted in it. The cylinder 1' is then pinched by rollers and rotated so that the cylinder is finished. Circumferential lengths Ln for the n-th hoops of the multilayer belt are thus sequentially provided. After six metal hoops with a circumferential length difference of about 2pit are combined together, a mandrel 7 is fitted in them to plastically deform the hoops so that the clearance between the adjacent hoops is made substantially zero. After that, the belt is divided into the individual hoops. The hoops are immersed in chemical polishing liquid to reduce the thickness of each hoop. This results in providing a lubricating oil film of uniform thickness.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for processing an endless belt made of gold, and more particularly to a method in which a gap for forming a lubricating oil film can be provided between each belt hoop layer.

From the viewpoint of durability, metal endless belts may be used as power transmission belts for automobile engines, generators, and the like. However, in this case, the bending caused by winding the belt around the pulleys cannot be ignored, and it is necessary to reduce the wall thickness of the belt. The additional grape weight cannot be increased too much.

Therefore, it is conceivable to fabricate a flexible and high-strength metal multilayer endless belt by stacking a large number of koji meat belt hoops of about 0.15 to 0.20 m/height thickness, for example.

However, when using such a metal multi-noodle belt,
Damage to the inside and outside of the belt due to mutual friction between each belt hoop is likely to occur.

ml by a conventional method such as a ring roll mill, etc.
However, in the method of forming individual belt hoops while forming the belt hoop, the forming precision is insufficient, so the gap between the layers is not constant, and the stress applied to each belt hoop is not constant, causing overload on a particular hoop. Circulation and wear caused by friction between the hoops can cause the hoops to become loose.

The present invention has been made in view of the above points, and is a method for forming fine gaps between the belt layers of an endless belt made by Sogen.
The metal multi-layer endless belt formed as follows is disassembled into individual belt hoops, and after reducing the thickness of both the inner and outer surfaces of each belt hoop, or either one of them, using chemical research, the belt hoops are assembled in multiple layers again. The main idea is to create a multi-layered endless belt.

In carrying out the present invention, first, the interlayer gap between adjacent belt hoops is substantially zero, that is, it is negligible.
It is necessary to manufacture an endless belt made of I4, and the following is the manufacturing process for such a metal endless belt. The process will be explained with reference to the drawings. Here, Figure 191 is a process diagram of the above manufacturing process, Figure 2 (for) is a diagram of the irregular OI of raw materials supplied to the same process, and Figure 2 (b) is a process diagram of the tube spinning process used in the same method. (C) is a schematic copper side view showing the state of ring mill processing of each single belt, (d) is a side cross section showing the state in which the core metal material is inserted into the multi-twisted belt. 3. As shown in Figure 1, gold 11411! The wood for the endless belt (the illusion is first made by preform machining (Fig. J62)
It is processed into a cylindrical shape as shown in a). Next, this wood 11), while still being fitted on the mandrel (2), is moved out of a punch-ILL which rotates reciprocally and slowly in the axial direction of the mandrel (2), and is formed into a thin-walled cylinder (1').

After cutting off the unnecessary ends (7), a core metal material is inserted into the center of the obtained thin-walled cylinder (1), and then the thin-walled cylinder (1) is placed on a work roller (4) as shown in Fig. 2 (C). and the tension roller (6) and the backup roller (5m).
), (5b), (5C) and rotate (
The thickness and length of the belt are roughly finished by ring milling (ring milling), and the belt is further cut into rings required for the belt. Through this ring mill processing, # lengths Ln corresponding to n eyelets of the multiple belts are sequentially formed. The gold w1411 with a difference of about 2πL obtained in this way!
Held (1-1), (1-2), ・, (1-n) are combined in a multi-11 m t6+ shape, and the core metal of heat-resistant steel has a larger thermal expansion coefficient than this metal belt. Material (71 to T

As a result, the multiple rings are plastically deformed between each layer and corrected to follow the dimensions of the core metal material, and then the entire ring is cooled and the core metal material is removed to obtain a multiple 10M endless belt with VFi heat in multiple layers. It is.

The method described above is based on one of the adjacent hoops of the multilayer endless belt.
This is an example of manufacturing a belt with substantially zero disability, and is a practical example of the present invention! The method for manufacturing the multi-layered belt used for this purpose is not limited to the above method.

In the present invention, the endless belt made of Kinmen, which is manufactured with substantially zero dovetail gap between adjacent belt hoops, is disassembled into single belt hoops, and each belt hoop is sent to Kagakuken. m> and then melt both the inner and outer sides, or use a one-sided 6-mask and green meat only the inner or outer side.
A gap is created between the hoops that corresponds to the inside of the hole, and chemical research liquids commonly used include phosphoric acid, copper silver, and the liver of alcoholic acid 1! Fluid II can be used, and the thickness of the polishing cap is adjusted depending on the type of polishing fluid, the type of polishing fluid, and the time of immersion in the fluid. Section 113: Shown is a mixture of H80: and HF as a polishing liquid (#combined ratio 20).
:1) was used to investigate the relationship between the stirring time and meat yield.

Thickness reduction by chemical polishing is unique in that it is done uniformly, making it suitable as a processing method for metal hyperactive belts that require uniformity in thickness. Because it can be controlled, the thickness of the layer is uniform.
In addition, the chemically polished surface of the belt hoop is smoothed, which increases the belt's fatigue life.
