description

At present, the rotary working device of the grader in some applications is mainly driven by the worm gear reduction box and the inner tooth of the rotary ring to drive the rotary mechanism to realize the rotary function. Due to the uncertain working environment during the working process of the grader, the shovel blade may be subjected to a large impact load during the scraping operation by misoperation or unexpectedly, such as the impact of a boulder in the soil, so the blade is affected The impact force of a large load will be transmitted to the meshing position of the slewing ring gear and the return gear of the worm gearbox, causing damage to the slewing ring gear and the slewing wheel of the worm gearbox, and also causing wear of the worm gear and worm. At present, most of the motor graders used on this type of motor grader are general worm gear reducers, which do not have a buffer function, or are equipped with safety protection devices, but the safety devices are not quickly uninstalled and the subsequent maintenance is inconvenient.

The slewing wheel is installed on the intermediate shaft of the worm gear box of the grader, the bushing is arranged between the slewing wheel and the intermediate shaft, the friction lining layer is arranged between the upper part of the slewing wheel and the shoulder of the intermediate shaft, and the friction block is arranged on the At the bottom of the slewing wheel, the friction block and the friction lining layer are sleeved outside the bushing, the ring-shaped pressure plate is installed under the friction block, and the disc spring is arranged on the lower side of the annular pressure plate; the adjusting nut is screwed to the bottom end of the intermediate shaft through the disc The pre-pressure of the spring and the adjusting nut compresses the friction block.

 Since the existing worm gear box safety protection device is placed in the worm gear box, once the overload protection device is aged and damaged, the worm gear box cover needs to be opened for replacement. The new design is easy to maintain because it can be replaced without disassembling the worm gear box. In addition, because the overload protection is installed at the slewing wheel, the impact force can be quickly released at the upstream of the impact force transmission. Therefore, compared with the existing type of worm gear box overload protection device installed on the worm wheel and the intermediate shaft, it is more advanced to avoid impact The force continues to be transmitted to the worm wheel and worm, causing them to wear. The structure is simple, the maintenance is convenient, and the cost is low. Installed under the worm gear box slewing wheel for easy maintenance.
