Track Roller D5H

At present, there are two types of roller structure of crawler construction machinery at home and abroad: straight shaft type and shoulder shaft type. according to

According to the design requirements, simple structure, good technology and few parts shall be selected, but the bearing axial force is slightly poor for excavation

Working condition of excavator type.

The roller is used to support the gravity of the machine. It rolls on the track link or track guide plate.

Therefore, it is used to clamp the track and prevent the track from sliding and derailing laterally. And drive the track on the ground when turning

Slide up side. The roller sometimes works in mud and water, and bears a large impact load. Therefore,

Reliable sealing, low wheel rim wear resistance and rolling resistance.

As the main load-bearing structure of the crawler loader, especially in the medium tonnage crawler loader, the design and manufacturing quality of the roller is directly related to the overall safety of the loader. The working condition of the crawler loader is complex, and only part of the rollers are stressed under some special working conditions or boom working conditions. Therefore, the arrangement of the rollers is in the form of dense middle and sparse ends. In order to meet the gradually increased weight of the crawler loader, the number and structural parameters of the rollers are increased correspondingly. The rollers are installed at the bottom of the crawler frame, forming rolling between the upper and lower surfaces of the crawler shoes when walking, and the rollers are installed The loading form is open in small and medium tonnage and closed in large tonnage
