The movable jaw group on the existing jaw crusher includes a movable jaw body, a movable jaw shaft assembly and a supporting bearing seat. The supporting bearing seat is fixed on the frame, and the movable jaw body is erected on the supporting bearing seat through the movable jaw shaft assembly. There is a movable jaw liner on the body; however, in the existing structure, the assembly process between the movable jaw shaft assembly and the supporting bearing seat is complicated and inconvenient to disassemble, which is embodied in the bearing and sealing ring in the movable jaw shaft assembly. After preheating, the interference sleeve is installed on the eccentric shaft, not only the processing procedure is complicated but also the disassembly is inconvenient, which leads to troubles in the daily maintenance of the movable jaw group

The invention relates to the field of mining equipment and in particular relates to a movable jaw group on a jaw crusher. A movable jaw body on the movable jaw group is erected on a supporting bearing block by virtue of a movable jaw shaft assembly, specifically, an eccentric shaft on the movable jaw shaft assembly is positioned by an inner self-aligning roller bearing to penetrate through the movable jaw body and is positioned and erected on the supporting bearing block by virtue of an outer self-aligning roller bearing; a withdrawal sleeve is arranged between the outer self-aligning roller bearing and the eccentric shaft; the outer self-aligning roller bearing and the eccentric shaft are supported and connected by virtue of the withdrawal sleeve, and a wheel-side sealing ring is fixedly connected; and during installation, the withdrawal sleeve can be hydraulically pressed by a tool, and during detachment, the withdrawal sleeve can be rapidly withdrawn by virtue of an oil-injection method, so that rapid detachment among the outer self-aligning roller bearing, the wheel-side sealing ring and the eccentric shaft can be realized, namely rapid detachment of the movable jaw group is realized, and daily maintenance of the movable jaw group is promoted.
Description
technical field [0001] The invention relates to the field of mining equipment, in particular to a movable jaw group on a jaw crusher. Background technique [0002] Jaw crusher is a kind of mining machinery used for crushing stone. Its principle is to simulate the movement of the two jaws of animals through the mutual engagement between the movable jaw set on the frame and the fixed jaw frame, so as to crush the material. . The movable jaw group on the existing jaw crusher includes a movable jaw body, a movable jaw shaft assembly and a supporting bearing seat. The supporting bearing seat is fixed on the frame, and the movable jaw body is erected on the supporting bearing seat through the movable jaw shaft assembly. There is a movable jaw liner on the body; however, in the existing structure, the assembly process between the movable jaw shaft assembly and the supporting bearing seat is complicated and inconvenient to disassemble, which is embodied in the bearing and sealing r...
