Description
Technical field
What the present invention relates to is a kind of pick-up unit, especially a kind of large-scale drive motor bearing shell detection system.
Background technology
In the prior art, known technology is the primary drive instrument of large-scale driving motor as modern large and medium-sized enterprise, and the key run well is produced in its safe operation.According to Principle of Electric Engine, large-size machine rotor air gap is only 7-15mm, and the even and stable of air gap is the key ensureing that motor runs, air gap clearance ensureing in the consistent type of axis normally by motor bearing.Current large-size machine, in operational process, often has motor gas-gap gap to change, and rotor sticks together the case generation of sweeping thorax and burning, and often brings about great losses to enterprise.And according to Principle of Electric Engine, because motor stator does not have external force, keep fixing.And rotor undertakes gearing by bearing shell, be often subject to the various radial direction from transmission side and axial impact force, excessive radial impact power easily cause the displacement of motor bearing from but air gap clearance change.And the impulsive force of axis easily causes the axial float of bearing shell, and then cause bearing bush abrasion, the damage of the aspects such as motor wiring, this is the weak point existing for prior art.
Summary of the invention
Object of the present invention is exactly for the deficiency existing for prior art, and a kind of technical scheme of large-scale drive motor bearing shell detection system is provided, the detection system of the program can detect the axial and radial side-play amount of large-scale driving motor bearing shell in real time, and can report to the police timely, significantly improve the security that large-scale driving motor runs, not only reduce the spot check difficulty of motor internal situation, achieve real-time detection and the historical record of this kind of situation simultaneously, for motor ruuning situation provides reference, the generation compared with heavy motor fault effectively can be avoided.
This programme is achieved by the following technical measures: a kind of large-scale drive motor bearing shell detection system, comprise monitoring alarm computing machine, the PLC be connected with monitoring alarm computing machine, described PLC is connected with driving control system, the feature of this programme is: described PLC is connected with the displacement transducer for detecting motor bearing shell, described sensor comprises the bearing shell shaft position sensor for detecting bearing shell axis, detect the bearing shell radial displacement transducer of bearing shell radial direction, detect the bush seat radial displacement transducer of bush seat, detect the bush seat shaft position sensor of bush seat.
Described bearing shell shaft position sensor is fixed in the bush seat of bearing shell side.The quantity of bearing shell shaft position sensor is n, n >=2.
Described bearing shell radial displacement transducer is arranged in the bush seat above bearing shell.
