Type F- Casting sheaves for cranesJB/T9005.9--1999
Replaces ZBJ80006.987
This standard applies to cast wire rope sheaves with sliding bearings (hereinafter referred to as sheaves) within the scope of the movable sheave block of the crane. Sheaves specified in this standard can also be used in other sheaves in wire rope transmission, such as fixed sheaves or other load-bearing parts except the movable sheave block.
2 Types and dimensions
2.1 The types and dimensions of type F sheaves are detailed in Figure 1 and Table 1. Marking example: bzxZ.net
Wire rope diameter d = 25mm. Pulley diameter L) = 630mm and diameter D, = 90mm F-type pulley, marked as: Pulley F25X630-90 JB/T 9005.9-—1999B:/2
Approved by the State Machinery Industry Bureau on 1999-06-28 448

JB/T9005.9
To facilitate the installation of the pulley, the axial clearance rate of each side should be specified in the connection structure to be at least 1mm.2 According to design requirements, B size is allowed to change. 2.2 The dimensions of the bushing (T) for F-type pulleys are detailed in Figure 2 and Table 2. Marking example:
Bushing (T) for F-type pulley with diameter D, = 90mm, marked as: JB/T 9005.9--1999
Bushing T90
Note: Lubrication grooves shall be opened as required.
