The invention discloses a balancing shaft mechanism of an engine. The balancing shaft mechanism of the engine comprises a balancing shaft chamber, an idle gear component, and balancing shaft gear components, wherein the balancing shaft chamber is fastened to an engine body; the idle gear component comprises an idle gear, an idle gear shaft sleeve, an idle gear wearing plate, an idle gear baffle and an idle gear fastening bolt; the idle gear shaft sleeve is mounted on the balancing shaft chamber, and fastened to the balancing shaft chamber through a first bolt and the idle gear wearing plate; the idle gear is mounted on the balancing shaft chamber through the idle gear shaft sleeve; the idle gear is positioned on the idle gear shaft sleeve through the idle gear baffle and a first positioning pin by the idle gear fastening bolt; the balancing shaft gear components are divided into two groups; each group of the balancing shaft gear components comprises a balancing shaft, a balancing shaft gear, a shaft sleeve, a baffle and a balancing shaft thrust plate; the balancing shaft thrust plates are fixed to the balancing chamber; the balancing shaft gear is compressed by the balancing shaft gear through the balancing shaft gear fastening bolt and the baffle. By adopting the mechanism, noises and the vibration of the engine are obviously reduced, and the balancing shaft mechanism is convenient to assemble and dismantle.
Description
technical field [0001] The invention relates to the field of engines, in particular to an engine balance shaft mechanism. Background technique [0002] The unbalanced second-order reciprocating inertial force in the in-line four-cylinder diesel engine with crankshaft is the main cause of vibration and noise when the diesel engine is working. Installing a balance mechanism is an effective means to solve the vibration and noise reduction problems of the in-line four-cylinder diesel engine. It is an inevitable trend for medium and small bore high-speed diesel engines to adopt balance mechanisms. [0003] The balance shaft mechanism is a commonly used balance mechanism. Adding a balance shaft mechanism to the diesel engine can balance the second-order reciprocating inertial force, so that the noise and vibration of the internal combustion engine can be significantly reduced. At present, there is a lack of corresponding engine balance shaft mechanism. [0004] The information d...
