Abstract

The invention discloses a gear transmission device, comprising a primary driving gear, a primary driven gear, a secondary driving gear and a secondary driven gear, the primary driving gear meshes with the primary driven gear, the secondary driving gear and The two-stage driven gear meshing is characterized in that the gear shaft of the first-stage driven gear and the gear shaft of the second-stage driving gear are respectively connected to both ends of the connecting rod, and between the gear shaft of the first-stage driven gear and the connecting rod and / or Or the gear shaft of the secondary driving gear and the connecting rod are connected through internal and external splines. The connecting rod connects the gear shaft of the first-stage driven gear and the gear shaft of the second-stage driving gear to realize the transmission of torsion between the two stages. The first-stage driven gear and the second-stage driving gear are independent of each other, so that the two-stage gear pairs are installed separately, which reduces the mutual influence of the two-stage gear pairs during assembly, reduces the difficulty of assembly, and reduces the processing accuracy requirements of components.

Description

technical field [0001] The invention relates to the transmission field, in particular to a gear transmission device. Background technique [0002] With the continuous improvement of the power level of aviation power and power used in various industries, the load transmitted by the gear transmission device is getting larger and larger. The single-way gear transmission cannot meet the demand for high-power power on the gear transmission device. Multi-way shunt gear transmission be increasingly widely used. [0003] In a two-stage multiplexed gear train, see figure 1 with figure 2 , usually the primary driven gear 20 and the secondary driving gear 30 (collectively referred to as the intermediate double gear) are designed as an integral structure or a non-detachable connection structure, such as a splined connection with an interference fit. When the gear train is assembled, after the first gear is installed, the mutual circumferential positions of the primary driving gear 1...
