この発明は、腐食液に接して使用する耐食鎖車
の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a corrosion-resistant chain wheel used in contact with a corrosive liquid.
従来の耐食鎖車は、ステンレス系鋳鍛鋼材また
はMCフイロン、ウレタン等の耐食と剛性のある
合成樹脂材を以つて、一体に鎖車を製作したが、
貴重な特殊材料を無駄に浪費する欠点があつた。 Conventional corrosion-resistant chain wheels were manufactured in one piece using stainless steel cast and forged steel materials or corrosion-resistant and rigid synthetic resin materials such as MC fillon and urethane.
The drawback was that valuable special materials were wasted.
この対策として鎖車に巻掛けるチエンのバレル

構造材による鎖車が望まれたが、適当な方法が得

車歯部の両側面を精密加工し、次に耐食剛性材よ

固着していた。 As a countermeasure to this problem, it was desired that the part of the chain that is wrapped around the chain wheel that comes into pressure contact with the barrel be made of a corrosion-resistant rigid material, and the rest be made of ordinary structural materials, but a suitable method could not be found. Therefore, we precision-machined both sides of the chain wheel tooth part using a general structural material as the base, and then manufactured a chain wheel tooth profile made of a corrosion-resistant rigid material by precision machining. It was firmly attached to the teeth of the table.
しかし、この方法では、腐食が進行する鎖車歯
形にチエンのバレルが均等に圧接しないため、鎖

ンのバレルを損傷する等の欠点があつた。 However, in this method, the chain barrel does not come into even pressure contact with the chain wheel tooth profile, which is subject to corrosion, resulting in looseness in the attachment of the chain wheel tooth profile and damage to the chain barrel.
この発明は、前記欠点に鑑み、チエンのバレル
と鎖車歯形が安定して圧接する耐食鎖車の製造方
法を提供することを目的とする。 SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide a method for manufacturing a corrosion-resistant chain wheel in which the chain barrel and the chain wheel teeth are in stable pressure contact.
この発明の実施例を図により説明する。 Embodiments of the invention will be described with reference to the drawings.

圧接する位置に確実に固定するのである。 FIG. 1 is a front view of the first embodiment, and FIG. 2 is a front view of the second embodiment. In FIG. 1, first, a tooth profile 1 having a tooth profile extending from the entire tooth part to the bottom of the chain wheel is formed from stainless steel material by pressing or casting and forging, and the front and rear ends of this tooth profile 1 are The cast piece 2 is also integrally extended and molded. Next, a mold 3 having the outer shape of a chain wheel is molded using a mold making machine. The tooth profile 1 is installed inscribed in the part corresponding to the tooth pattern of the molded chain wheel mold 3, and then molten metal of a general structural metal material is poured into the chain wheel mold 3, and the molded chain wheel mold 3 is made of a general structural metal material. The chain wheel base 4 fuses the casting pieces 2 together and securely fixes the tooth profile 1 in the position where the chain barrel 5 comes into pressure contact.

着するものである。 Figure 2 shows the manufacturing direction when the chain wheel rotates in one direction, and shows the tooth contour 6 that forms the tooth profile of the stainless steel material in the area where the chain barrel 5 comes into pressure contact.
, and is fixed to the chain wheel base 8 using the casting piece 7 protruding from the toothed contour 6 in the same way as in the first embodiment.

Both ends of the chain wheel 6 are rolled up, and the chain wheel bases 4 and 8 are no longer lifted up and peeled off, and they mesh smoothly with the chain.
