Problems solved by technology

The existing cantilever vacuum couch roll includes a roll body and a vacuum box. The vacuum box is placed inside the roll body. The vacuum box head on the operation side is supported on the suction seat, and the vacuum box head on the transmission side is supported on the transmission side journal through bearings. Due to the wear of the bearing position is one of the common faults of vacuum couch rolls, the bearing journal and the vacuum box on the transmission side usually need to be disassembled during maintenance. The maintenance operation is complicated and the working hours are long, which reduces the production efficiency.

Abstract

The invention provides a supporting structure of a vacuum box of a suction couch roll. According to the supporting structure of the vacuum box of the suction couch roll, the structure is simple, the repair is convenient and is short in time consuming, and the adverse effect on regular production can be effectively lowered. The supporting structure comprises a driving side vacuum box head and a journal, wherein the journal sleeves the driving side vacuum box head. The supporting structure is characterized in that the axial length of the driving side vacuum box head is greater than that of the journal, the driving side vacuum box head is located at the outer side of the journal, a bearing seat is arranged on the driving side vacuum box head, and an inner bearing cover of the bearing seat is fixedly connected with the journal.

Description

technical field [0001] The invention relates to a roll of a paper machine, in particular to a support structure for a vacuum box of a vacuum couch roll. Background technique [0002] The vacuum couch roll is an important part of the paper machine. It is the roller at the end of the working stroke of the forming wire where the paper web is peeled off from the forming wire. The existing cantilever vacuum couch roll includes a roll body and a vacuum box. The vacuum box is placed inside the roll body. The vacuum box head on the operation side is supported on the suction seat, and the vacuum box head on the transmission side is supported on the transmission side journal through bearings. The inner end face of the vacuum couch roll is one of the common faults due to the wear of the bearing position. When the bearing is maintained, the journal on the transmission side and the vacuum box usually need to be disassembled. The maintenance operation is complicated and the working hours ...
