Description
技术领域technical field
本发明属于发动机技术领域,具体涉及一种降噪齿轮及发动机。The invention belongs to the technical field of engines, and in particular relates to a noise reduction gear and an engine.
背景技术Background technique
本部分提供的仅仅是与本公开相关的背景信息,其并不必然是现有技术。This section provides background information related to the present disclosure only and is not necessarily prior art.
发动机的齿轮传动过程中会受热膨胀,实际加工装配时存在误差等因素,在加工齿轮时必须通过人为调整的方式,留出合适的齿轮侧隙,避免齿轮由于热膨胀及偏心安装等原因在工作时发生齿面干涉甚至卡住,导致传动失效。由于轮齿在传递扭矩时,由于齿轮副的齿轮之间存在齿轮侧隙,啮合不平滑,导致初始阶段啮合时产生碰撞冲击,且齿轮驱动的附件在获取动力的同事也承受了一定的冲击载荷,导致发动机产生的噪音较大。The gears of the engine will be heated and expanded during the transmission process, and there are factors such as errors in the actual processing and assembly. When processing the gears, it is necessary to manually adjust the way to leave a suitable gear backlash, so as to avoid the thermal expansion and eccentric installation of the gears during work. Tooth surface interference or even jamming occurs, resulting in transmission failure. When the gear teeth are transmitting torque, due to the gear backlash between the gears of the gear pair, the meshing is not smooth, resulting in a collision impact during the initial stage of meshing, and the gear-driven accessories also bear a certain impact load while obtaining power , resulting in louder engine noise.
现有技术中的降噪齿轮一般由第一齿轮、第二齿轮及销钉三部分组成,销钉能够穿设第一齿轮和第二齿轮,以实现第一齿轮和第二齿轮的连接,使得第一齿轮、第二齿轮作为一个复合齿轮使用,用于与传动齿轮进行啮合传动。在销钉的外部套设有橡胶套,依靠橡胶套的弹性作用使得第一齿轮和第二齿轮之间错开一定的角度,实现第一齿轮和第二齿轮分别与传动齿轮相贴合,从而消除齿轮间的侧隙。The noise reduction gear in the prior art generally consists of three parts: the first gear, the second gear and the pin. The pin can pass through the first gear and the second gear to realize the connection between the first gear and the second gear, so that the first The gear and the second gear are used as a compound gear for meshing transmission with the transmission gear. There is a rubber sleeve on the outside of the pin, relying on the elastic effect of the rubber sleeve to make the first gear and the second gear stagger a certain angle, so that the first gear and the second gear are respectively fitted with the transmission gear, thereby eliminating the gear the side gap between.
采用这种方式,由于第二齿轮的回位需要靠橡胶套的弹性保证,但是橡胶套在工作过程中被反复挤压受力,橡胶套容易碎裂损坏或失去弹性,橡胶套的有效使用寿命较低,从而影响侧隙消除效果。同时,橡胶套刚度无法评估,若刚度过大容易造成传动齿轮因热涨而卡死的情况,无法保证齿轮传动副的正常工作。In this way, since the return of the second gear needs to be guaranteed by the elasticity of the rubber sleeve, but the rubber sleeve is repeatedly squeezed and stressed during the working process, the rubber sleeve is easily broken, damaged or loses elasticity, and the effective service life of the rubber sleeve Lower, thus affecting the effect of backlash elimination. At the same time, the rigidity of the rubber sleeve cannot be evaluated. If the rigidity is too high, the transmission gear may be stuck due to thermal expansion, and the normal operation of the gear transmission pair cannot be guaranteed.
