Jie standard defines the type, basic parameters and dimensions of type 1 intermediate disc gear coupling (hereinafter referred to as coupling). This standard is applicable to transmission systems that connect two non-directional shafts. The rotation diameter of the coupling end is 130~-1000mm. The nominal torque transmitted is G.3~3150kN·m. The angular offset when working load is 3”. When there is no working load, the directional offset is 5 pieces. WGJ type intermediate disc gear coupling.

3.3.2 Marking rules
3.3.2..6 The marking of the chain coupling shall comply with the provisions of GB/T3852. Approved by Guodong Machinery Industry on September 30, 1998 and implemented on December 1, 1998. IB/T8821-1998 3.3.2.2 The marking rule for the coupling with no braid connection for hydraulic assembly and disassembly with interference fit is to mark Ur before the diameter of the shaft hole according to the provisions of JB3/T6186. 3.2.3 The marking rule for the flat hole shaft is to add \EK before the diameter of the shaft hole, that is, BKd, × B × L 3.3.3 Marking example Example W4A type coupling, the distance between the two shaft ends is -1m. Active type shaft hole, A type, = 120mm, L = 167mm. Driven type shaft hole, d, = 120 mm, t, = 167mm, B = 55mmWGJ4 coupling
