Embodiment Construction

[0045] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0046] Such as figure 1 Shown is the structure of the transmission speed reducer of the multi-roller drive straightener involved in the present invention. The actual armature current of the drive motor in the state of deterioration of the bearing of the No. 4 straightening roller reducer of the large H-shaped steel straightening machine is as follows: figure 2 shown.

[0047] By comparing the actual armature current of the motor before and after the deterioration of the bearing of the straightening roller reducer, it can be known that, no matter in the no-load or loaded state, once the bearing of the straightening roller reducer ...

Abstract

The invention discloses a monitoring method for bearing deterioration state of a transmission speed reducer of a multi-roller driving straightening machine, wherein the control program comprises the following functional units: an actual armature current sampling control unit, a motor armature current sampling number control unit, No. 2, No. 4, No. 6 and No. 8 straightening roller transmission motor steady-state no-load armature current sampling and average value calculation control units, No. 2, No. 4, No. 6 and No.8 straightening roller transmission speed reducer bearing deterioration state judging subunits. By adopting the technical scheme, the state information of the transmission bearing failure can be accurately obtained in time, so that the machine maintenance personnel can process the speed reducer capable of carrying out deterioration of the transmission bearing in time so as to avoid serious damage to the straightening roller transmission speed reducer.

Description

technical field [0001] The invention belongs to the technical field of monitoring the running quality of a mechanical transmission mechanism. More specifically, the present invention relates to a method for monitoring the deterioration state of a bearing of a transmission reducer of a multi-roller drive straightener. Background technique [0002] The large H-beam production line of Maanshan Iron and Steel No. The upper straightening rollers and the five lower straightening rollers are arranged in a staggered manner up and down. [0003] The four upper straightening rolls are active straightening rolls, respectively numbered No. 2 straightening roll, No. 4 straightening roll, No. 6 straightening roll and No. 8 straightening roll. Each upper straightening roll is controlled by a power The 220KW DC motor is driven by a reducer; the transmission reducer of each upper straightening roller is a four-stage variable speed. [0004] The five lower straightening rolls are passive s...
