Dual-input gear pair type high-torque gearbox

Abstract

The invention discloses a dual-input gear pair type high-torque gearbox. The dual-input gear pair type high-torque gearbox comprises a box body. The box body is provided with a first gear and a second gear which are in engaged transmission. The second gear is connected with an input shaft. The box body is further provided with a first output shaft, a second output shaft, a first gap bridge shaft and a second gap bridge shaft. A first gear set is arranged on the first gap bridge shaft. A second gear set is arranged on the second gap bridge shaft. The first gear set and the second gear set are in engaged transmission through a third gear, and the third gear is coaxially connected with the first gear. The first gear set is in key connection with the first output shaft. The second gear set is in key connection with the second output shaft. According to the dual-input gear pair type high-torque gearbox, traditional single gear pair input is changed into dual gear pair input, a traditional way that one input force drives two output resistances is changed into the way that two input forces drive two output resistances, and superposition of input torques is achieved.

Description

technical field [0001] The invention relates to a gear box, in particular to a double-input gear pair high-torque gear box. Background technique [0002] Gearboxes are widely used in plastic, rubber, chemical fiber extruders and other equipment. The performance of the gearbox determines the production efficiency of the extruder, and also determines the price of the equipment and its market competitiveness. [0003] The traditional gearbox is a single-gear pair input, which drives two screws for extrusion operation, and one input force drives two output resistances. The relatively small torque is very laborious, and the matching motor can only be relatively small. The safety factor in the design In the case of relatively high requirements, a large gearbox is required, but this not only feels top-heavy but also makes the machine cost high and the appearance is not beautiful.
