Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、ベルトカバー、特に内燃機関のタイミングベルトを覆うベルトカ バーに関する。 The present invention relates to a belt cover, and more particularly to a belt cover that covers a timing belt of an internal combustion engine.

【0002】[0002]

【従来の技術】[Prior Art]

内燃機関では、カムシャフトスプロケット、クランクシャフトスプロケットお よびオイルポンプスプロケットの間にタイミングベルトが掛けられている。その タイミングベルトは、主にゴム製の材料で形成されている。タイミングベルトの 周りは異物などの巻き込みを防止するためにベルトカバーで覆われている。ベル トカバーは樹脂製ものが多用されている。 In internal combustion engines, a timing belt is hung between the camshaft sprocket, crankshaft sprocket and oil pump sprocket. The timing belt is mainly made of rubber material. The area around the timing belt is covered with a belt cover to prevent the inclusion of foreign matter. The belt cover is often made of resin.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

上記ベルトカバー内は気密性が保持されるようになっているが、完全に気密状 態を保持することはその構造上、困難である。そして、タイミングベルトは、湿 気の多い雰囲気ではその強度の劣化が著しく、ベルト寿命が短くなるという問題 点がある。 The inside of the belt cover is kept airtight, but it is difficult to completely keep the airtight state due to its structure. Further, the timing belt has a problem that the strength thereof is significantly deteriorated in a humid atmosphere, and the belt life is shortened.

【0004】 本考案はベルトカバー内の雰囲気の湿気を減らし、ベルトの強度の劣化を防止 することを目的とする。An object of the present invention is to reduce the humidity of the atmosphere in the belt cover and prevent the deterioration of the belt strength.

【0005】[0005]

【課題を解決するための手段】[Means for Solving the Problems]

本考案はベルトカバーのすくなくとも一部を二重構造に構成し、その二重構造 の内壁に開孔を設け、上記内壁とベルトカバーと間に除湿剤を封入したことを特 徴とするベルトカバーにある。 The present invention is characterized in that at least a part of the belt cover has a double structure, an opening is provided in the inner wall of the double structure, and a dehumidifying agent is enclosed between the inner wall and the belt cover. It is in.

【0006】[0006]

【作用】[Action]

ベルトカバーのすくなくとも一部を二重構造にし、その二重構造の内壁とベル トカバーとの間に除湿材を封入したので、ベルトカバー内の雰囲気の湿気が除湿 材に吸引され、湿気が減少して、ベルトの強度の劣化が防止される。 At least a part of the belt cover has a double structure, and the dehumidifying material is enclosed between the inner wall of the double structure and the belt cover. As a result, deterioration of the belt strength is prevented.

【0007】[0007]

【実施例】【Example】

本考案の一実施例を図1,2に基づいて説明する。 An embodiment of the present invention will be described with reference to FIGS.

【0008】 図1,2において、ベルトカバー1は、カバー11とそのカバーの内部に間隔 をおいて配置された内壁12との二重構造で構成され、内壁12には複数の開孔 12aが穿設されている。カバー11と内壁12との間の空隙には、塩化カルシ ウムなどで構成される除湿剤13が封入されている。In FIGS. 1 and 2, the belt cover 1 has a double structure including a cover 11 and an inner wall 12 that is arranged inside the cover at a distance, and the inner wall 12 has a plurality of openings 12 a. Has been drilled. A space between the cover 11 and the inner wall 12 is filled with a dehumidifying agent 13 composed of calcium chloride or the like.

【0009】 符号14,15はカムシャフトスプロケット、16はクランクシャフトスプロ ケット、17はオイルポンプスプロケット、18はアイドラプーリ、19はテン ショナプーリ、20はタイミングベルトをそれぞれ示している。カバー11は、 通気性の良好なもので構成され、外気との換気を可能にしている。Reference numerals 14 and 15 are camshaft sprockets, 16 is a crankshaft sprocket, 17 is an oil pump sprocket, 18 is an idler pulley, 19 is a tensioner pulley, and 20 is a timing belt. The cover 11 is made of a material having good air permeability and allows ventilation with the outside air.

【考案の効果】[Effect of the device]

本考案によれば、ベルトカバーの二重構造にし、その二重構造の内壁とベルト カバーとの間に除湿材を封入したので、ベルトカバー内の雰囲気の湿気が除湿材 に吸着され、湿気が除去されることにより、ベルトの強度の劣化を防ぎ、ベルト の寿命を延ばすことができる。 According to the present invention, the belt cover has a double structure, and the dehumidifying material is enclosed between the inner wall of the double structure and the belt cover. By being removed, deterioration of the strength of the belt can be prevented and the life of the belt can be extended.
