しくはリンクプレートの嵌合とピン又はブツシユ
嵌合部分の改良に関する。[Detailed Description of the Invention] The present invention relates to a conveyor chain used in a corrosive environment such as a seawater dust remover or a water treatment chain, and specifically relates to improvements in the fitting of link plates and the fitting portion of pins or bushes.

察すると、第４図に示すように、圧延方向にクラ
ツク１１が無数に存在し、破壊はそのうちの１個
を起点として発生していることがわかつた。 Generally, as shown in FIG. 1, the conveyor chain 1 includes an outer link 5 in which two link plates 2 are connected by a pin 3, and two similar link plates 2 connected by a bush 6. The inner link 9 rotatably supports the roller 7.
The pins 3 are inserted into the bushes 6 so that they are connected in an endless manner. and,
As shown in FIG. 2, the link plate 2 is usually manufactured by press punching a rolled material such as flat steel. The holes 10 are also formed at the same time by a press multi-stage feeding process. For this reason,
Due to the large thickness of the plate 2, the press punched surface of the fitting hole 10 is rarely a smooth sheared surface, and most of it is formed as a rough fractured surface. Then, connect plate 2 like this to chain 1.
When a fatigue test was carried out by incorporating this into a new model, it was found that the starting point of fatigue always occurred from a part of the rough fracture surface. Furthermore, when observing the vicinity of the starting point of the fatigue using a microscope, it was found that there were countless cracks 11 in the rolling direction, as shown in FIG. 4, and the fracture occurred from one of them as the starting point.

つている。 On the other hand, the fatigue strength of conveyor chains used in corrosive environments such as seawater is low, and in this case as well, it was recognized that the crack 11 is the starting point of fracture. As a result, in a corrosive environment, corrosive substances stay and concentrate in the crack, forming a corrosion cell between the crack and the smooth part, resulting in the formation of a deep pit 11a, which exerts a large notch effect. This is considered to be a factor in the fatigue failure of the link plate 2. Furthermore, conveyor chains used in corrosive environments generally have pins 3 and bushes 6 made of stainless steel; in this case, link plates 2 made of ordinary steel and pins 3 made of stainless steel are used.
The bushing 6 and the bushing 6 come into contact with each other at the fitting hole 10, resulting in so-called contact corrosion of different metals, which causes ordinary steel with a low corrosion potential to corrode, contributing to a decrease in fatigue strength.
そこで、第５図に示すように、本出願人によ

も、高疲労強度となるコンベヤチエーンが提案さ
れている（実願昭55−115657号参照）。 Therefore, as shown in FIG. 5, the applicant attached a hardening resin 12 to the fitting hole 10 of the link plate 2 to seal the fitting hole, thereby preventing corrosive substances from linking. A conveyor chain that prevents contact with the fitting hole surface of the plate and has high fatigue strength even in a corrosive environment has been proposed (see Utility Model Application No. 115,657/1987).

ることができない虞れを生じている。 However, in this conveyor chain, the pins 3 or the bushes 6 were fitted with the curable resin 12 simply attached to the fitting holes 10 of the link plate 2, so when the pins etc. were fitted, the curable resin 12 There is a risk that the fitting hole 10 may not be reliably sealed because it is scraped off.

Alternatively, it is an object of the present invention to provide a conveyor chain in which the gap between the bushing and the bushing is filled with a curable resin, thereby eliminating the above-mentioned drawbacks.
以下、実施例に基づき、本考案を具体的に説明

接着される。 As shown in FIG. 6, the pin 3 has two grooves 13, 13 formed in the circumferential direction at the portion where it fits into the link plate 2. Then, a thermosetting resin 12 is applied to the fitting hole 10 of the link plate 2, and a similar resin 12 is applied to the grooves 13, 13 of the pin 3. In this state, when the pin 3 is inserted into the fitting hole 10, the resin 12 in the groove 13 is compatible with the resin 12 attached to the fitting hole 10, and there is a gap between the fitting hole 10 and the pin 3. Spread evenly. Furthermore, when heat is applied to the fitting portion between the link plate fitting hole 10 and the pin 3, the resin 12 in the groove 13 expands in volume and oozes into the fitting gap.
At the same time, the resin 12 hardens and the pin 3 is securely inserted into the link plate fitting hole 10 through the resin 12 of a predetermined thickness and the resin 12 in the groove 13. Glued. On the other hand, as shown in FIG.
is formed, and like pin 3, bush 6
The link plate fitting hole 10 into which the link plate fits is completely sealed, and the bush 6 is securely bonded to the fitting hole 10.

Further, as shown in FIG. 9, the grooves 13 may be formed in a cross-over manner so as to be inclined in the circumferential direction to more reliably prevent the pin 3 (or the bush 6) from rotating. Similarly, the grooves may be formed in a wavy or zigzag shape, or an axial groove may be provided so as to connect two circumferential grooves to ensure that the pin or the like is prevented from rotating or coming off. Further, in the above embodiment, the hardening resin 12 is applied to both the fitting hole 10 and the pin 3 or the bush 6 for fitting, but the resin may be applied to only one of them for fitting.

いコンベヤチエーンを得ることができる。 As explained above, according to the present invention, the groove 13 extending in the circumferential direction is formed in the fitting hole 10 of the link plate 2 or the fitting portion of the pin 3 or the bush 6, and the groove and the fitting hole are connected to each other. Since the gap between the pin or bushing is filled with the curable resin 12, when fitting the pin or bushing into the fitting hole,
The resin is not scraped off, and the resin in the groove is compatible with and oozes out, so that the resin spreads almost uniformly into the fitting gap, and the fitting hole can be reliably sealed, and the pin or bushing can be sealed. is firmly adhered to the link plate to prevent it from turning and coming off, and in particular, the grooves extending in the circumferential direction ensure that the link plate does not come off, and the impact force is applied by the interposition of a resin of a predetermined thickness. However, the elastic force of the resin provides a buffer, preventing the pin or bush from rotating or coming out. As a result of the above effects, it is possible to completely seal the fitting hole 10 reliably and for a long period of time, and the fitting hole does not come into contact with corrosive substances, so that the corrosive substances remain in the crack 11. - It is possible to prevent the formation of deep pits due to concentration, and furthermore, it is possible to prevent contact corrosion of different metals, and it is possible to obtain a conveyor chain with high fatigue strength even in a corrosive environment.
