D65P-7 Bulldozer Track Roller

D65P-7 bulldozer track roller

A bulldozer track roller is an essential component of a bulldozer's undercarriage system. It is designed to support the whole weight of the bulldozer and transfer it to the ground for excellent traction. The roller is composed of a metal frame that is shaped like a cylinder with an axle inside that allows it to roll along the tracks. The outer surface of the roller is made up of a high-quality rubber material that provides optimum grip and enhances the life of the tracks. The bulldozer track rollers are also fitted with grease fittings to allow proper lubrication, which improves durability and lowers maintenance costs. In conclusion, a bulldozer track roller is crucial to the efficient performance of a bulldozer, and a robust one can help increase productivity, reduce downtime, and achieve better results.

Collars are made by ductile iron. It shows exceptional resisitance to shock.

Models of bulldozer undercarriage parts are as below:

D20,D21,D30,D31,D39EX-15,D40,D41P-6,D41-3,D41-5,D50,D51,D60,D65,D65-8,D65-12,D65EX-15,D80,D85,D85-18,D85-21,D85EX-15,D85PX-15 ETC..

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
