Problems solved by technology

[0002] The rack and pinion lifting equipment overcomes some shortcomings of the traction lifting equipment, but in the existing rack and pinion lifting equipment technology, when the axes of the transmission shafts intersect, it is common to use ordinary bevel gear transmission (also known as bevel gear), (for example, the rack-and-pinion drive elevator disclosed in Application No. 201410618629.2 uses a plurality of bevel gears); and for ordinary bevel gear transmission, the cone tops of the two bevel gears must overlap, and the axial error will cause serious Therefore, the ordinary bevel gear transmission of important equipment must have a special anti-dislocation design to prevent the separation of the cone top; according to the gear principle, the transmission ratio of the commonly used ordinary bevel gear transmission fluctuates within a certain range, which is not conducive to The stable operation of the system; while the face gear transmission can significantly improve the above-mentioned shortcomings of the ordinary bevel gear transmission

Abstract

A rack-and-pinion lifting device with face gear transmission, characterized in that the transmission system includes a face gear transmission system, and the motor system includes a permanent magnet DC motor system or a permanent magnet AC synchronous motor system; the face gear transmission system includes a first-stage Drive gear shaft, primary face gear, secondary drive shaft, secondary drive gear, secondary face gear, driving drive shaft, left driving gear, left driven gear, left driven gear shaft, right driving gear, right driven Gear, right driven gear shaft; face gear transmission is significantly larger than ordinary bevel gear transmission; pinion gear is not affected by axial force, which can simplify support and reduce system weight; at the same time, the common normal line of the meshing tooth pair is the same, for power The transmission is extremely beneficial; the face gear transmission can ensure the transmission with a fixed transmission ratio, which is conducive to improving the stability of operation and reducing vibration and noise; it can significantly improve the operation efficiency and quality, save materials, save energy, and protect the environment.
