Double gear coupling: the highest circumferential speed of about 60m/s, with 0 or 1 grease lubrication, dosage for full coupling, fat cycle of 6-12 months, for better lubricant adhesion, lax sealing requirements; the highest circumferential speed of about 60m/s, N150, N220 gear oil lubrication, the amount of half. Coupling capacity, no leakage to rest, 12 months Huanyouzhouqi, plum type elastic coupling of lax sealing requirements; maximum circumferential speed of about 150m/s, N150, N220 gear oil lubrication, requires sufficient flow along the axial direction continuously through the coupling, no seal.

Single head gear coupling: the highest circumferential speed of about 60m/s, with 0 or 1 grease lubrication, dosage for full coupling, fat cycle of 6-12 months, for better lubricant adhesion, lax sealing requirements; the highest circumferential speed of about 60m/s, N150, N220 gear oil lubrication, the amount of half the coupling capacity, no leakage to rest, 12 months Huanyouzhouqi, ordinary mineral oil, poor sealing requirements; the highest circumferential speed of about 30m/s, with 0 or 1 grease lubrication, dosage for full coupling, fat cycle 6 months, lubrication requirements of adhesive agent is not strict the demand for sealing.

Embedded coupling: the highest circumferential speed of about 150m/s, with N150, N220 gear lubrication, requiring sufficient flow, along the axial continuous through the coupling, without sealing.

Spring type coupling: the highest circumferential speed of about 30m/s, with 1 grease lubrication, dosage is filled with couplings, grease change cycle 1000 hours, the sealing requirements are lax.

Disc spring coupling: the highest circumferential speed of about 60m/s, with 2 or 3 grease, was filled with a quincunx elastic coupling, fat cycle for 12 months, has not strict sealing requirements; the highest circumferential speed of about 150m/s, N150, N220 gear oil lubrication, requires sufficient flow along the axial direction of continuous by coupling.

Cross slider coupling: the highest circumferential speed of about 30m/s, with 2 grease lubrication, the middle slider gap filled with grease, grease change cycle 1000 hours, suitable for ball bearing grease. The maximum circumferential speed is about 30m/s, lubricated with N220 gear oil, the gap of the middle slider is filled with oil, the oil change cycle is 1000 hours, and sometimes the impregnated felt pad is used.
