As a conventional chain guide G, for example, the 6th chain guide
As shown in the figure, the chain system layout provided in an internal combustion engine consists of a chain C stretched between a drive sprocket A connected to the crankshaft and a driven sprocket B connected to a drive system such as a valve system. It is known that the equipment mounting section 1 can be set so that the chain guide shoe 2 is positioned accordingly. The chain tensioner D that applies tension to the chain C is generally installed on the slug (loose) side, and the chain guide G is installed on the tension side, but the chain C that passes through the chain guide G on the tension side is driven. Since it is pulled by sprocket A, lubricating oil is supplied to the area where drive sprocket A and chain C are involved in order to reduce chain wear and ensure smooth operation. For this purpose, an oil jet E is provided protruding from the engine body, and the engine is lubricated with oil injected from this oil jet E.

にもコスト的にも不利であつた。 However, in such a conventional chain guide G, there is no forcible oil supply to the chain sliding surfaces.In other words, the oil sprayed from the oil jet lubricates the driving sprocket and the driven sprocket, but in the process Since the oil supply structure was such that the oil would be scattered and there would be insufficient oil in the area leading to the chain guide, the chain guide shoe that was in contact with chain C was likely to wear out, which only led to problems with durability. However, a chain guide and an oil jet for lubrication must be provided separately, which is disadvantageous in terms of layout and cost.

The purpose of this product is to provide a chain guide that has a smooth chain sliding surface, prevents wear and noise of the chain and guide, greatly extends its service life, and is easy to manufacture and assemble at a low cost. It is something.

An example in which the present invention is applied to an internal combustion engine will be explained with reference to FIGS. 1 to 5. A drive sprocket A connected to a crankshaft and a driven sprocket B connected to a drive system such as a valve are A chain C is tensioned in an endless manner so that it can run freely, and is provided with a chain guide G on the tension side and a chain tensioner D on the slack side. The chain guide G is integrally formed with a chain guide shoe 2 in a substantially L-shape through a guide plate 21 in the equipment mounting part 1, and an oil flow communicating with the lubricating oil supply port 3 in the equipment mounting part 1. The passage 4 is provided as a groove or slot, and the outlet 5 is connected to the chain C through a communication hole 51 communicating with the oil passage 4.
An opening is provided on the surface of the chain guide shoe 2 on which the chain guide shoe 2 slides. In this case, the equipment mounting part 1 is fixed to the engine body 9 with tightening bolts 8, and the oil flow path 4 is surrounded by the side of the engine body as an oil passage, and the oil filler port 3 communicates with the oil pump (not shown) of the engine.
A nozzle 6 is provided so that the oil flows out from the outlet 5 and can be injected in the direction of the drive sprocket A, and a part of the oil flows through the chain sliding surface of the chain guide shoe 2. The surface and other parts are adapted to supply oil to drive sprocket A.

宜形態に形成される。 The chain guide shoe 2 is constructed by welding a rubber or synthetic resin member with an outlet 5 to the guide plate 21 , but it can be made by selecting a member or structure that can be substituted for other shoes. . In addition, the position of this outlet 5 is preferably placed at an upstream position in consideration of the direction of movement of the chain C. Furthermore, depending on the characteristics of each engine, a refueling hole is placed at a location where the chain C interferes with the runout guide. There may be cases where it is provided. In addition, a porous member 7 or an orifice (not shown) is attached to the hydraulic system path, for example, the oil flow path 4 leading to the shoe 2, to reduce the oil pressure.
This prevents oil from protruding from the outlet 5 opened in the shoe 2. Further, the oil passage provided in the chain guide plate 21 is formed into an L-shape by drilling a flat plate and then bending the same, but it can be formed into an appropriate shape.

運転が可能となる。 After the internal combustion engine is started, oil is sent from the oil pump to the oil flow path 4 through the oil supply port 3, and the outlet 5 on the surface of the chain guide shoe 2 of the chain guide G becomes a lubrication supply port, allowing the oil to flow out and drive the engine. Lubricating oil can also be supplied from the nozzle 6 to the meshing part between the sprocket A and the chain C.
Therefore, after the driven sprocket B has been lubricated, the chain C has little oil adhering to it, and the sliding movement with the chain guide G is not sufficiently lubricated, but oil flows out from the lubrication supply port opened in the chain guide shoe 2. As a result, the chain and chain guide shoe 2 can be sufficiently lubricated, allowing smooth and safe operation.

In the present invention, an oil flow path 4 communicating with a lubricating oil system path communicating with a lubricant supply source is bored in the chain guide so as to span over the equipment mounting portion 1 and the guide plate 2 1 where the chain guide shoe 2 is located. The outlet 5 formed in the oil flow path 4 is opened on the surface of the chain guide shoe 2 on which the chain slides, and the sprocket and the chain are connected to each other. Since the nozzle 6 for injecting oil onto the surface is provided as an opening in the equipment mounting part 1, the engagement surface of the chain is supplied with oil and the operation is accurate and safe, and sufficient security of the engagement part can be maintained. In addition, the sliding surface with the chain is always lubricated to make it easier to slide, reducing wear on the chain guide shoe and chain, preventing noise generation, enabling smooth operation, and the chain guide itself has an oil jet. Since it can be used as a structure, the number of parts is small, manufacturing and assembly are simple, and layout is easy, which has the practical effect of significantly reducing costs.
