Elevator traction machine brake friction material production is to fully stir resin, rubber, fiber and other friction performance modifiers, fully extrude and fuse them through a rubber mixer, and then go through preforming, hot pressing, vulcanization, and machining products made by other processes.
1.The pretightening torque of bolts see table 1
2.Add solidified gule (Loctite 243) to part No.5
3.MachiningthearcR345oflining bythe datum of plane A and 4-016.5 on No.1, protect all the holes of No.1 before machining. and clean up all holes after machining.
1.Type of Lining: D-007
2.Surface even, no lacunas, no nicks
3.Hardness is HRR70+ 10
4.Frictional coefficient 0.42~0.56(Test method references to the provisions of GB 5763 6.3 friction performance test.
5.Internal shear strength>10MPa.
1Material hardness: 160-210 HBW The surface of the cast should be glabrous.
2.The inner stress should be eliminated by temper after casting.
3.Unstated fillets: R3
4.Deburr and chamfer.
5.All the chamfers that aren't labeled are: 0.5x45°
6.The tolerance that isn’t labeled is according to the GB/T1184-1996(K).
7.The non-machined surfaces and surface I Il should be painted. And the surface painting RAL9005, requirements see R000000306.
