Claims

[Scope of utility model registration request]

The timing belt, which is bridged between the crank pulley connected to the crankshaft and the cam pulley connected to the camshaft, located on the side of the engine body, is pressed from the outside by a tensioner to apply a predetermined tension to the timing belt, The tensioner is comprised of an inner cylinder and an outer cylinder rotatably arranged around the outer circumference of the inner cylinder and in contact with the timing belt, and a bolt for inserting a bolt into the inner cylinder for fixing the tensioner to the engine. hole,
The timing belt tension adjustment device, which is applied to engines that use a type that is eccentrically drilled with respect to the center of rotation of the outer cylinder, has a socket on the jig body that fits with the tensioner fixing bolt mentioned above. A nut runner attached to the jig body so as to protrude from the front, a cylindrical rotating body rotatably disposed around the outer circumference of the socket so as to be coaxial with the socket, and a nut runner attached to the inner cylinder of the tensioner. In order to fit into the drilled adjustment hole and rotate the tensioner around the bolt in the pre-tightened state, an adjustment pin is drilled forward from the periphery of the rotary cylinder, and the adjustment pin A servo motor for rotating a rotary body having a pin until it reaches a preset torque, and a jig body having the nut runner and rotary body are positioned on the side of the engine body. 1. A timing belt tension adjustment device comprising a positioning pin that projects forward from a position and that fits into a desired hole on an engine body.
