Application and advantages of excavator copper sleeve

Application of excavator copper sleeve

The excavator is divided into the upper part, the lower part, and the working device part. The lower part is mainly the walking mechanism, and the upper part is mainly the control. The working device, as the name suggests, is the part used to work. The excavator is the big arm, the forearm, the bucket, and some have rippers. The most important thing is the hydraulic system, main pump, main valve, pilot system and so on. The application of excavator copper sleeve in hydraulic excavators has 12 applications of self-lubricating bearings, which are mainly used in parts such as booms, sticks, chassis running mechanisms, body parts, and hydraulic components.

The structural parts of the excavator working device and the oil cylinder are connected by a pin at each connection hinge point and the supporting seat, which bears a large load during operation, and the wear between the mutually moving parts is also large. At the same time, the load-bearing characteristics of the excavator working device are as follows: High load and low speed.

In addition, when the excavator excavates and transports soil, the working device rotates frequently and the frequency of repeated actions is high under the action of each oil cylinder, that is, the relative movement of the grinding parts is frequent, in order to ensure that the various parts of the work rotate flexibly and work Reliable, so the solid excavator copper sleeve is suitable for the working device of the excavator.
