Electromagnetic brake failure

Text: [Big] [middle][small] Release date: 2014-4-1  Views: 251
Electromagnetic clutch and electromagnetic brake before installation must clean, remove rust fat and sundry.

Wet type electromagnetic clutch work, must add lubricant between the friction plate, using (1) water lubrication oil lubrication; (2) the oil bath lubrication, immerse in parts of the oil is about 5 times the size of the clutch; (3) axis lubrication oil, in the high-speed and high-frequency action axis oil supply methods should be adopted.

Electromagnetic clutch, electromagnetic brake can coaxial installation, can be divided into shaft installation, axial must be fixed, the active part and the driven part are not allowed to have axial channeling, shaft installation, alignment between the active part and the driven shaft should be no greater than 0. LMM.

Tooth type electromagnetic clutch when installation, must guarantee that a certain gap between end face gear, no grinding phenomenon when idle, but shall not be greater than the delta value.

Power supply and control circuit, clutch power supply for dc 24 volts (special orders except). It consists of three-phase or single-phase ac voltage by the step-down and full-wave rectifier (or rectifier bridge), no voltage stability and flat wave requires large enough power. Not allowed to use half-wave rectifier power supply.

Electromagnetic clutch, electromagnetic brake for class B insulation, normal temperature 40 ℃. Speeding limit working temperature of heat balance when not allowed to 100 ℃, otherwise the coil and the friction parts are prone to damage.
