Tension gauges for timing belts of automotive engines

摘要

The present invention relates to a tension gauge for a timing belt of an automotive engine, and more particularly, to a tension gauge for a timing belt of an automotive engine, which can easily recognize a tension state of a timing belt, a housing in which a bent groove is formed at a lower end thereof, A motor built in the housing and driven in accordance with the ON operation of the switch; A worm gear coaxially mounted on a rotary shaft of the motor; A worm that meshes with the worm gear and moves to the vertical axis by the rotational force of the worm gear according to the rotation of the motor; A lever whose one end is hinged to the upper end of the worm and whose center is hinged to the housing and is pivoted according to the upward / downward movement of the worm; A plurality of contact portions for emitting a signal to display a turning force applied to the lever on the display device by making an electrical connection short circuit by the lower end of the worm; A rod hinge-fixed to the other end of the lever and moved up and down according to the rotation of the lever, thereby pushing the end of the timing belt on the upper end of the timing belt to push the timing be A leaf spring having both ends fixedly formed in the housing to hold elasticity in a state in which the lower end of the timing belt can be seated; An action protrusion protruding from a lower surface of the leaf spring to a position corresponding to the rod; And a piezoelectric element embedded in the housing so as to be positioned under the operation protrusion and electrically connected to the display device.
