Shaft coupling structure of calendaring machine

Abstract

The invention provides a shaft coupling structure of a calendaring machine. The shaft coupling structure of the calendaring machine has the advantages that the disassembly and the maintenance are simple and convenient, the coaxiality of shaft assembling can be guaranteed, and the service life is improved. The shaft coupling structure of the calendaring machine comprises a first connecting piece and a second connecting piece. The shaft coupling structure of the calendaring machine is characterized in that a cone-shaped convex block is arranged on the axial inner side end face of the second connecting piece in an external convex mode, and a cone-shaped groove matched with the cone-shaped convex block is formed in the axial inner side end face of the first connecting piece; a flat key is arranged on the end face where the cone-shaped convex block is attached to the cone-shaped groove, the flange portion of the first connecting piece is connected with the flange portion of the second connecting piece through a pin, the first connecting piece and the second connecting piece are both provided with a pressing plate in a sleeved mode, and the inner side end faces of the pressing plates are arranged on the outer side end faces of the pin in a pressing mode; first connecting holes are both in the shape of a cone, and the larger radial end face of each connecting hole is located at the outer side of the first connecting piece; a cone-shaped sleeve is arranged in the corresponding connecting hole in a matched mode, and motor output shafts of the calendaring machine are arranged in axial mounting holes of the cone-shaped sleeves respectively.

Description

technical field [0001] The invention relates to a shaft connection device of a calender, in particular to a shaft coupling structure of a calender. Background technique [0002] The existing shaft coupling of the calender includes two connecting pieces with similar structures. The flange parts at the axial ends of the two connecting pieces are connected and fastened by adding bolts and nuts. The keyway, when assembling, the shaft and the shaft hole on the coupling adopt an interference fit, the maintenance and replacement of the coupling or shaft is inconvenient, and after many times of assembly and disassembly, the reduction of the interference will affect the coaxiality of the shaft assembly , Secondly, the wear of the coupling of the calender mostly occurs on the connecting piece that cooperates with the output shaft of the motor, and then the bolt is threaded with the flange, and the thread wear after long-term use will increase the axial misalignment of the coupling.
