Description

Technical Field

[0001] The utility model relates to the technical field of the textile industry, in particular to a driving wheel fixing mechanism of an electric transport vehicle. Background Art

[0002] The upper axle car is a commonly used equipment in the workshop. It is used to move the weaving shaft to the loom, saving time and effort. However, since the upper axle car needs to be installed with a drive wheel to drive forward and turn, the mounting hole of the drive wheel itself is not suitable for direct installation on the car body, and the drive wheel will be subjected to corresponding axial force and radial force during the movement of the car body, so the installation method needs to be selected. The existing method is to simply install the various components of the drive wheel on a flat plate through a deep groove ball bearing and a matching bearing seat, which occupies a large area, is inconvenient to install, and affects the use of space. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] In view of the deficiencies in the prior art, the utility model provides a driving wheel fixing mechanism for an electric transport vehicle, which replaces the original deep groove ball bearing and bearing seat with a cross roller bearing and is directly connected to the various components of the driving wheel. It occupies a small area and is easy to install. The axial force and radial force that it can withstand are also much greater than the required force.

[0007] Furthermore, the outer ring of the cross roller bearing is connected to the flat plate, the outer ring of the drive wheel connecting circle is connected to the inner ring of the cross roller bearing, and the inner ring of the drive wheel connecting circle is connected to the drive wheel shaft.

[0008] Furthermore, the inner ring of the cross roller bearing can rotate.

[0009] Furthermore, the driving wheel shaft is provided with a shaft retaining spring connected to the driving wheel shaft, and the driving wheel connecting circle is provided with a sprocket connected to the driving wheel connecting circle.

[0010] Furthermore, the countersunk hole on the outer ring of the bottom of the driving wheel shaft is connected to the driving wheel pad block.

[0011] Further, a flat key connected to the drive wheel shaft is provided on the drive wheel shaft.

[0012] Further, the flat plate is located in the connecting member, and the connecting member is used for installation in an electric forklift.

[0013] The operation of this solution is as follows: First, the installer installs the outer ring of the crossed roller bearing onto the flat plate to be installed. Then, the drive wheel elevation block is installed on the drive wheel, and they are installed through the counterbore on the bottom outer ring of the drive wheel shaft and the drive wheel elevation block. At this time, the entire installed drive wheel assembly needs to be inserted into the inner ring of the crossed roller bearing through the drive wheel shaft. After that, take out the drive wheel connection circle. First, install its inner ring on the drive wheel shaft, and then install its outer ring on the inner ring of the crossed roller bearing. Finally, insert the flat key into the drive wheel shaft groove, install the sprocket corresponding to the position of the flat key into the drive wheel shaft, and then install the shaft circlip.

[0014] Compared with the prior art, the drive wheel fixing mechanism of this electric forklift uses a crossed roller bearing to replace the original deep groove ball bearing and bearing seat, directly connecting to each component of the drive wheel. It occupies a smaller area, is convenient for installation, and the axial force and radial force it can withstand are far greater than the required forces. BRIEF DESCRIPTION OF THE DRAWINGS
