Description

Gear meshing floating adjusting mechanism Technical Field The invention relates to the technical field of automatic logistics systems driven by gears and racks, in particular to a gear meshing floating adjusting mechanism. Background In an automatic logistics system, a traveling shaft of a high-precision logistics trolley (RGV) or a large-specification stacker is generally supported and guided by adopting a top rail and a bottom rail or a double rail on the bottom surface, an output gear and a rack are driven by a motor drive reducer to carry out meshing transmission to realize long-distance driving of the traveling shaft, the parallelism of installation of the guide rail and the rack is critical to traveling operation, once the installation parallelism exceeds a tolerance value, the phenomenon of extra strength and clamping stagnation occurs, a motor load is raised, the motor generates heat and cannot normally operate, a motor can be burnt out in severe cases, a rack and a rack are damaged, in order to ensure the parallelism of the rack and the guide rail, so that the rack and the rack are well meshed, the existing technical scheme is to precisely process a rack installation base and the guide rail installation base, the base length is generally longer (more than 4 meters), the large-specification machine tool is required to process, the cost is very high, in order to reduce deformation and vibration cutters in the processing, the base structure needs enough rigidity and rigidity, the aging destressing treatment is also caused by more than twice, if the traveling distance is longer (more than 20 meters), the installation period is difficult, the automatic adjustment is carried out, the automatic adjustment period is shortened, or the manufacturing period is shortened, the period is shortened, and the meshing period of the gear and the noise is shortened, but the noise is not prolonged, but the horizontal transmission period is shortened.
