The eccentric shaft assembly of the hydraulic cone crusher includes an eccentric shaft, a gear frame, an eccentric bushing and an eccentric gear. At the same time, the eccentric shaft is installed in the body cavity of the lower frame. In order to prevent wear of the lower frame, the eccentric shaft is in contact with the bush in the cavity. Generally speaking, the dyeing gap between the eccentric shaft and the bushing is 1.5 mm, and the dyeing gap between the lower frame and the bushing is 0.22 mm. If not handled properly, the lower frame body will wear out, so the eccentric components The smooth operation of the system is very important.
　　 Generally, the following factors affect the smooth operation of the eccentric component of the hydraulic cone crusher: 　　 1. Wear of the wear plate under the eccentric component
　　 Structurally, the wear plate supports the entire assembly, but when worn, the force during the support process cannot be balanced, so the entire assembly cannot run smoothly.
　　 2. Casing quality is unqualified
　　 The bushing is of poor quality and cannot meet the requirements. It is often replaced. However, due to the strict installation requirements of the bushing, the lower frame body and the eccentric shaft, the replacement is very troublesome. If not handled properly, the components will not run smoothly.
　　3, eccentric assembly block wear
　　During the operation of the hydraulic cone crusher equipment, the eccentric component moves upward due to the force of the helical gear. At this time, the upper s per acts as a s per. This part is usually 0.2mm. If worn, the equipment will vibrate violently, and the eccentric bushing will easily bite into the bushing of the lower frame.
