The invention relates to the technical field of transmission devices, in particular to a tensioning device. According to the scheme, the engine tensioner structure comprises a shell and is characterized by further comprising a valve body, a through hole is formed in the top end of the shell, a sealing bolt is inserted into the through hole, a mechanical rotation structure is arranged at the tail end of the through hole and comprises an outer plunger and an inner plunger located in the outer plunger, and the valve body is located on the side of the mechanical rotation structure; an oil way is arranged between the valve body and the cavity in the mechanical rotation structure. The engine tensioner structure solves the problems that in the prior art, arrangement is not compact enough, installation is complex, rollback is prone to occurring, and repeated assembly and use are difficult, and achieves the purposes of being high in adjusting precision, capable of preventing rollback, efficient in oil pressure management, high in durability and reliability, easy to maintain, compact in arrangement and capable of reducing the leakage risk.
本发明涉及传动装置技术领域,尤其涉及张紧装置。方案如下:一种发动机张紧器结构,包括外壳,其特征在于,还包括阀体,外壳顶端设有通孔,通孔内插入密封拴,通孔末端设有机械旋回结构,机械旋回结构包括外柱塞与位于外柱塞内的内柱塞,阀体位于机械旋回结构的侧方,阀体与机械旋回结构内的空腔之间设有油路。解决了现有技术中布置不够紧凑,安装复杂,容易产生回退且难以重复装配使用的问题,本发明提出了一种发动机张紧器结构,达成了调节精度高、防止回退、油压管理高效、耐用性和可靠性高、易于维护、布置紧凑和减少泄露风险的目的。
