Embodiment Construction

[0035]The present invention is a chain guide mechanism capable of integrally supporting constituent elements including a plurality of sprockets, a chain wound around the plurality of sprockets, and a fixing for sliding and guiding the chain by a frame. The specific embodiment of the chain guide and the swing chain guide may be arbitrary as long as the swing chain guide includes a cylinder protruding outward from one of the side surfaces in the width direction of the guide. The frame is provided with a sprocket support part for supporting the plurality of sprockets by winding the chain; a fixed chain guide support part for supporting the fixed chain guide; and a swinging The chain guide holding portion holds the mounting boss portion in a dummy fitting state, and the rocking chain guide holding portion is configured to be able to extend from the side along one of the side surfaces of the rocking chain guide. Insert the mounting sleeve part.

Abstract

The purpose of the present invention is to provide a chain guide mechanism in which all constituent elements can be easily integrated with a simple configuration, and which is capable of improving workability during assembly and maintenance. Specifically, the chain guide mechanism (100) of the present invention is configured so as to be capable of integrally supporting components including a plurality of sprockets (101, 102, 103), a chain (105), a fixed chain guide (160), and a rocking chain guide (170) by means of a frame (110), the frame (110) being provided with a rocking chain guide holding section (140) for holding a mounting boss section (180) on the rocking chain guide (170) in a virtual fitting state, and the rocking chain guide holding section (140) being configured so as to hold the mounting boss section (180) on the rocking chain guide (170) in a virtual fitting state. The rocking chain guide holding section (140) is configured so that the boss section (180) can be fitted into and attached to the rocking chain guide holding section (140) from the side.

Description

technical field [0001] The present invention relates to, for example, a chain guide mechanism suitable for a timing system of an engine in which a chain is tension-maintained and slide-guided by a chain guide, the chain being wound around a crankshaft and a camshaft respectively provided in the engine compartment between the sprockets. Background technique [0002] Conventionally, a chain guide mechanism for a timing system is known, which is installed in an engine room of an automobile, and which can slide and guide a chain moving between sprockets and maintain the chain tension appropriately. [0003] Some types of chain guide mechanisms include, for example, a rocking chain guide and a fixed chain guide. The rocking chain guide is mounted on the slack side of the chain movement path so as to be rockably mounted on the engine block, which is the installation object. The fixed chain guide is fixed to the engine block on the tension side of the chain travel path. [0004] ...
