description

The tension spring is a mechanical part that uses elasticity to work. It is a part made of elastic materials deform under the action of external force, and return to their original shape after removing the external force. Also used as "spring". Generally made of spring steel. The types of springs are complex and diverse. According to the shape, there are mainly spiral springs, scroll springs, leaf springs, and special-shaped springs. A spring is a mechanical part that uses elasticity to work. After the crawler walking device of hydraulic excavator is used for a period of time, the distance will increase due to the wear of the chain rail pin, and the entire crawler will be stretched, resulting in friction of the crawler frame, derailment of the crawler, and increased noise of the walking device, which affects the excavator. The operating performance. Therefore, each track must be equipped with a tensioning device so that the track can always maintain a certain degree of tension. There are many types of crawler-type tensioning devices, which can be divided into spiral tensioning devices and hydraulic tensioning devices. At present, hydraulic tensioning devices are widely used in crawler walking devices of hydraulic excavators. The tensioning device with auxiliary hydraulic cylinder presses the grease into the hydraulic cylinder for lubrication through the lubricating gun, so that the piston extends outwards, one end moves the guide wheel, and the other end compresses the spring. After pre-tensioning, the spring has a proper stroke to play a buffering role. The adjustment distance of the front and rear guide wheels is greater than 1/2 of the track pitch, so that when the track is excessively stretched due to wear, the track can be connected after the chain track is removed. The tightness of the track should be adjusted appropriately. Put the wedges on the front and lower part of the guide wheel, brake the walking device, and then slowly drive the track to connect it to the tension of the part. At this time, the upper rail will sink. The sag can be measured by placing a ruler on the supporting wheel and the driving wheel, and it should usually not exceed 3 to 4 cm.
