Background
The basic structure of the existing gearbox is that a driving shaft and a driven shaft are arranged on a box body, and the driven shaft is driven by the driving shaft through a transmission mechanism. In the existing gearbox, each output shaft is independent, so that the torque in one direction can be output along the axis of each output shaft. In some special equipment, when two coaxial rotating shafts are arranged in one set of working mechanism and the two rotating shafts are required to work simultaneously, the existing gear box is adopted to meet the requirement, two gear boxes are required to be arranged to respectively drive the two rotating shafts, and in addition, when the two sets of working mechanisms are symmetrically arranged and work simultaneously, four gear boxes are required to be arranged, so that the complexity and the size of the equipment can be increased, and the manufacturing cost of the equipment is greatly increased.
SUMMERY OF THE UTILITY MODEL
The present invention aims to provide a bidirectional output gearbox which can respectively transmit two torques on the same axis in two directions.
In order to achieve the purpose, the utility model adopts the following scheme: a first worm, a second worm, a first output shaft and a second output shaft are arranged on a box body, the second output shaft is a hollow shaft, the second output shaft is in clearance fit with the first output shaft, a first worm wheel and a second worm wheel are respectively connected to the first output shaft and the second output shaft, the first worm is meshed with the first worm wheel, the second worm is meshed with the second worm wheel, one end of the second output shaft is connected with a driving gear, one end of the first output shaft is provided with a driven gear in clearance fit with the first output shaft, an intermediate shaft is arranged on the box body, two ends of the intermediate shaft are respectively connected with a first intermediate gear and a second intermediate gear, the driving gear is meshed with the first intermediate gear, and the driven gear is meshed with the second intermediate gear.
According to the scheme, when the gearbox is used, the first worm and the second worm are respectively connected with a power device (a motor or a hydraulic motor), the first worm and the second worm are respectively driven by the two power devices, the first worm drives the first output shaft through the first worm wheel, the second worm drives the second output shaft and the driving gear through the second worm wheel, the driving gear drives the driven gear through the first intermediate gear, the intermediate shaft and the second intermediate gear, one end of the first output shaft and the driving gear positioned at the end can output two coaxial torques in one direction, and the other end of the first output shaft and the driven gear can output two coaxial torques in the other direction.
The utility model has compact and reasonable structure and reliable performance, and can simultaneously provide torque for the rotating shafts of a plurality of working mechanisms in a set of equipment, thereby simplifying the structure of the equipment, reducing the size of the equipment and reducing the cost of the equipment.
