Roller auxiliary safe and stable connecting structure

Abstract

The invention relates to the technical field of roller installation, in particular to a roller auxiliary safe and stable connecting structure. The roller auxiliary safe and stable connecting structurecomprises a roller and a motor; a static connecting disc is fixedly installed on the motor; the outer wall of one end of the roller is sleeved with a movable connecting disc; the movable connecting disc is in threaded fit with one end of the roller; the static connecting disc and the movable connecting disc are connected through a telescopic rod; a shaft groove is arranged in the roller; an output end of the motor is clamped in the shaft groove in a sliding mode; a damping cavity is arranged in the static connecting disc; the outer wall of the static connecting disc is sleeved with a hollow piston; the piston is installed in the damping cavity in a sliding mode; and the piston is connected to the damping cavity through a connecting piece. According to the invention, through the arrangement of an early warning assembly and a linkage structure, the automation effect is achieved, a worker does not need to check the device regularly; and the worker can know the situation at the first timein case of an emergency.

Description

technical field [0001] The invention relates to the technical field of roll installation, more specifically, a roll-assisted safe and stable connection structure. Background technique [0002] The roll is the main working part and tool for continuous plastic deformation of the metal on the rolling mill. The roll is mainly composed of three parts: roll body, roll neck and shaft head. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roll neck is installed in the bearing, and the rolling force is transmitted to the stand through the bearing seat and the pressing device. [0003] The traditional connection structure between the roll and the output shaft of the motor has a single function and poor stability. After the roll has been working for a long time, it is prone to fall off, and the staff needs to check the connection between the roll and the motor regularly, and there is no ...

[0003] The traditional connection structure between the roll and the output shaft of the motor has a single function and poor stability. After the roll works for a long time, it is prone to fall off, and the staff needs to check the connection between the roll and the motor regularly, and there is no early warning function. , the staff can no longer know the occurrence of the accident for the first time
