Abstract
The invention relates to the technical field of transmission, discloses a transmission device based on an electric appliance spline shaft, and solves the problems that when a motor drives a rotating shaft to rotate and the vertical height of the rotating shaft needs to be changed, the position of the motor also needs to be changed synchronously, and actual operation is relatively inconvenient. A key groove matched with the spline shaft is formed in the inner wall of the supporting sleeve, the supporting sleeve penetrates through the mounting base, a first bearing is arranged at the penetrating position of the supporting sleeve and the mounting base, a rotating shaft is arranged above the mounting base and penetrates through the mounting base, a second bearing is arranged at the penetrating position of the rotating shaft and the mounting base, and the rotating shaft and the supporting sleeve are connected through a transmission unit. A rotating driving mechanism matched with the rotating shaft is arranged on the mounting seat, and a first fixing plate is arranged below the mounting seat; the spline shaft can be independently driven to move in the vertical direction, the position of the rotation driving mechanism is not changed while the height of the spline shaft is changed, and actual use is facilitated.
Description
technical field [0001] The invention belongs to the technical field of transmission, in particular to a transmission device based on a spline shaft of an electrical appliance. Background technique [0002] The transmission device is an intermediate device that transmits the motion and power of the prime mover to the working mechanism. The spline shaft is a kind of mechanical transmission. There is a longitudinal keyway on the surface of the shaft, and the rotating part sleeved on the shaft also has a corresponding keyway. Rotate synchronously with the axis. While rotating, some can also slide longitudinally on the shaft. In the prior art, the rotating shaft is driven by a motor to rotate. When the vertical height of the rotating shaft needs to be changed, the position of the motor also needs to be changed synchronously, which is inconvenient in actual operation. , the existing technology still needs to be improved. SUMMARY OF THE INVENTION [0003] In view of the above s...
