Problems solved by technology

Of the two devices, although the belt-type rotary transmission mechanism does not require lubricating oil due to the use of rubber parts for meshing drive, its durability is not as good as that of the chain-type rotary transmission mechanism, and the chain-type rotary transmission mechanism uses metal-to-metal contact. Lubricating oil is required for meshing, but its durability also becomes better

Abstract

A chain case (6) for an engine (1), comprising a front wall (601), an end inner wall (18f) disposed toward one end of a cylinder block (2) at predetermined intervals, and left and right side walls (602) , extending from the peripheral edge of the front wall (601), which is superimposed on the side wall of the cylinder block to be integrally connected thereto, and forms a chain housing chamber (13) when integrally connected to the cylinder block, which is used for the engine ( The chain case (6) of 1) is characterized in that: the pump chamber (161) is formed on the thickened part (28), and the thickened part (28) is formed from the left between the rear wall surface (fc) and the front wall surface (fd) of the casing. 1. A part of the right side wall (602) protrudes, wherein the rear wall surface (fc) of the housing is superimposed on the opposite surface (F) of one end of the side wall of the cylinder body, and the front wall surface (fd) is located opposite to the end surface (F) side, it is also characterized in that the pump cover (45) is used to close the through hole to form a water pump (16), and the pump cover (45) makes the pump shaft (44) rotatably fastened, and the pump shaft is assembled in the pump chamber ( The pump impeller (43) in 161) is integrated as a whole.

Description

technical field [0001] The present invention relates to a chain case structure, which accommodates a chain transmission system for connecting the engine crankshaft and a valve drive system or a valve mechanism, in particular to a chain case structure integrated with a water pump, and the chain case structure is integrally fixed to one end of a cylinder block on the cylinder side wall. [0002] The present invention also relates to a chain-type rotary transmission system that uses an endless chain to transmit the rotation of the engine crankshaft to the valve train or valve train via the camshaft, and more particularly to a chain housing structure for covering a chain tensioner that applies tension to the chain . Background technique [0003] The engine uses a rotary transmission mechanism to transmit part of the rotational force of the crankshaft arranged at the lower part of the engine cylinder block to the valve mechanism to open the intake valve and exhaust valve provide...
