Abstract

The present invention relates to a torsion spring and a rotary gear and, more particularly, to a mounting structure of a rotary gear and a torsion spring which is configured to be capable of not onlyforward rotation but also reverse rotation, and which is applicable to an EGR valve. Provided according to a first embodiment of the present invention is a mounting structure of a torsion spring capable of reverse rotation and a rotary gear, comprising: a torsion spring; a rotary gear having gear teeth formed on an outer circumferential surface thereof and a rotary shaft extending downward from the center thereof, wherein the torsion spring is mounted on an outer circumferential surface of the rotary shaft; at least two guide bars protruding downward from an outer upper surface of the rotary gear and restricting movement of one end and the other end of the torsion spring; and a fixing portion covering the rotary gear and machined on an inner surface of a housing forming an outer surface ofan EGR valve, wherein the torsion spring includes a ring for fixing a body, and the fixing portion covers the ring for fixing the body and prevents the ring for fixing the body from rotating.

Description

technical field [0001] The present invention relates to a torsion spring and a rotating gear, in particular to an installation structure of the torsion spring and the rotating gear, which is configured so that the torsion spring applicable to an EGR valve can not only rotate forward but also reversely. Background technique [0002] In general, exhaust gas recirculation (EGR; EXHAUST GAS RECIRCULATION) refers to a technology that recirculates a part of exhaust gas from an engine to an intake system of the engine, thereby using the exhaust gas and external air for combustion. Since the exhaust gas is recirculated, there is an advantage in that NOx emitted from the vehicle into the atmosphere can be reduced. [0003] As an important technology among the above-mentioned EGR technologies, there is an EGR valve. [0004] The role of the EGR valve is to adjust the recirculation amount of the exhaust gas flowing from the exhaust pipe to the suction branch pipe side or mixed with ex...
