The design of hydraulic jack for chain tightening, 2-stroke electronically controlled diesel engine

摘要

The present invention relates to an electronically controlled large engine chain hydraulic tightening device, and an electronically controlled large engine chain hydraulic tightening device that reduces the number of installation of a hydraulic jack for tightening a chain that transmits power from an engine operation to a driven shaft from a crankshaft. It is about.;In order to achieve the above object, the present invention provides a chain of an engine including a crank pulley installed on a crankshaft, a plurality of driven pulleys connected to and linked to the crankshaft by a chain, and a tension pulley for retightening the chain. A hydraulic tightening apparatus, comprising: a support installed on an upper portion of a beam positioned in a direction in which the tension pulley is to be pulled; A hydraulic jack installed to be supported by the support; A stud connected to the hydraulic jack and having an end coupled to the shaft of the tension pulley through the beam; The technical gist of the present invention includes a nut coupled to the stud so as to be positioned above the beam, and configured to fix a tension pulley coupled to the stud to the beam.;Engine, Chain, Pulley, Shaft, Stud, Hydraulic Jack, Hydraulic Pump Nut, Support
