Abstract

The invention discloses a gear driving device. The gear driving device comprises a primary driving gear, a primary driven gear, a secondary driving gear and a secondary driven gear, wherein the primary driving gear is engaged with the primary driven gear, and the secondary driving gear is engaged with the secondary driven gear. The gear driving device is characterized in that a gear shaft of the primary driven gear and a gear shaft of the secondary driving gear are connected with the two ends of a connecting rod respectively, the gear shaft of the primary driven gear and the connecting rod are connected in a matching mode through inner and outer splines, and / or the gear shaft of the secondary driving gear and the connecting rod are connected in the matching mode through the inner and outer splines. The connecting rod is connected with the gear shaft of the primary driven gear and the gear shaft of the secondary driving gear so that torque transmission between two stages is achieved. The primary driven gear and the secondary driving gear are mutually independent so that two stages of gear pairs can be independently mounted; mutual influence during assembly of the two stages of gear pairs can be reduced; the assembly difficulty is reduced; the machining accuracy requirement of components is lowered.

Description

Technical field [0001] The invention relates to the field of transmission, in particular to a gear transmission device. Background technique [0002] With the continuous improvement of the power level of aerospace power and the power used in various industries, the load transmitted by its gear transmission is getting larger and larger. The use of single-channel gear transmission cannot meet the demand for high-power power gear transmission. Multi-channel shunt gear transmission Has been increasingly widely used. [0003] In the two-stage multi-way splitter gear train, see figure 1 with figure 2 Generally, the primary driven gear 20 and the secondary driving gear 30 (collectively referred to as intermediate double gears) are designed as an integral structure or a non-detachable connection structure, such as a spline connection with interference fit. When assembling the gear train, after one gear is installed, the mutual circumferential positions of the primary driving gear 10 and ...
