Abstract

Provided is a chain tension applicator which can play wear resistance function by dispersing and reducing load imparted from a plunger at backstop and reducing processing accuracy and processing load (needed) during component machining and assembling period. A chain tension applicator includes: a plunger 120 protruding to a drive chain; a housing 110 having a plunger slide hole 111 in which the plunger 120 forms a protrusile insert cooperation; a protruding bias spring 130 of the bias plunger 120; a pair of wedge-shaped cams 140, 140 engaged on two racks 121, 121, the racks 121, 121 are formed at an opposite position where the outer circle of the plunger 120 is divided into at least two parts. The wedge-shaped cams 140, 140 are embedded with space on a cam slide seat 112 which is gradually becoming thin and is formed on the front end side of the opening of the plunger slide hole 111.

Description

technical field [0001] The present invention relates to a chain tension applying device for applying an appropriate tension to a power transmission chain arranged in an automobile engine, and the chain tension applying device is particularly called a chain tensioner for a timing chain , the timing chain transmits rotation between the sprocket on the crankshaft side and the sprocket on the camshaft side. Background technique [0002] A conventional chain tensioning device known as a tensioner has a structure in which a plunger protruding from a housing presses the back surface of the tensioner lever brake shoe surface of the tensioner lever; A conventional chain tensioning device utilizes a plunger protruding from a housing to slide into contact with the slack side of the chain by squeezing the back surface near the rotating end of a tensioner lever that is rotatably supported to the engine body side; so the brake shoe surface of the tensioner lever is in sliding contact wit...
