Products Introduction
Changzhou Tianniu Transmission is a professional manufacturer of electromagnetic clutch (brake), overrunning clutch, safety clutch, machine tool pin, clutch friction plate, brush and auxiliary accessories. The company has high-level production technicians and advanced production technology. It has developed and produced more than 20 series and nearly 1000 specifications of products at home and abroad.
Products are widely used in mechatronics, machine tools, instruments and meters, light industrial machinery, food machinery, tobacco machinery, printing machinery, packaging machinery, papermaking machinery, textile machinery, cement mining equipment, steel rolling equipment, automobile equipment, lifting and transportation equipment, medical equipment, office equipment, fishery ships, etc.
We also provide customized and maintenance for the clutch of imported equipment.
Dry single-plate electromagnetic clutch: When the coil is energized, a magnetic force is generated. Under the action of the electromagnetic force, the spring plate of the armature is deformed, the moving plate and the "armature" are attracted together, and the clutch is in an engaged state; when the coil is powered off, the magnetic force disappears, the "armature" bounces back under the action of the spring force, and the clutch is in a disengaged state.
Dry multi-disc Wet multi-disc electromagnetic clutch: The principle is the same as above, and several friction pairs are added. The torque of the same volume is larger than that of the dry single-disc electromagnetic clutch. The wet multi-disc electromagnetic clutch must be cooled and lubricated by oil when it works.
