Abstract

The invention provides a hydraulic shock absorption and noise reduction gear structure. The structure comprises pressing devices, a driving gear, a tensioning gear, a pressing nut and a driving shaft,the periphery of one end of the driving shaft is sequentially sleeved with the driving gear and the pressing nut, the driving gear comprises a first gear and a sleeving ring which are coaxially arranged, the driving shaft is sleeved with the first gear and the sleeving ring, and the sleeving ring is sleeved with the tensioning gear; and one end of the sleeving ring is fixedly connected with the first gear, the other end of the sleeving ring is fixedly connected to the pressing nut, the multiple pressing devices are installed on the side wall of the sleeving ring, one ends of the pressing devices abut against the inner ring of the tensioning gear, and the periphery of the tensioning gear and the periphery of the first gear are both meshed with a main force bearing gear. According to the hydraulic shock absorption and noise reduction gear structure, the driving gear is provided with an oil way, the pressing devices are installed, pressure oil is provided through the oil way of the driving shaft, and the pressing devices enable the driving gear and the tensioning gear to be in a reverse tensioning state all the time, so that backlash is eliminated, and the shock absorption and noisereduction effects are achieved.

Description

technical field [0001] The invention belongs to the field of engines, and in particular relates to a gear structure for hydraulic damping and noise reduction. Background technique [0002] Gears generally have gear teeth, tooth grooves, end faces, normal faces, addendum circles, dedendum circles, base circles, and index circles. When two gears mesh, the addendum of one gear always enters the root of the other gear. , in order to prevent thermal expansion and have a space to store lubricating oil, the height of the dedendum is required to be greater than the height of the addendum. A large number of gears are used in the engine for transmission. The gear transmission is accurate and reliable, but the gear transmission will produce a certain amount of noise, mainly due to Vibration is generated when the gear transmits torque, and the backlash of the gear is the main source of vibration. Contents of the invention [0003] In view of this, the present invention aims to propos...
