JB/T 9005.1--1999
This standard adopts DIN15061:1977 Part 1 "Rope groove section of wire rope pulley for lifting device" in a non-equivalent manner
This standard is a revision of ZBJ80006.1-87 "Rope groove section of cast pulley for crane". During the revision, only editorial modifications were made to the original standard, and the main technical content remained unchanged. This standard is part of the JB/T9005 "Cast Pulley for Crane" series of standards, which includes the following 10 parts: JB/T 9005.1-—1999

This standard replaces ZBJ80006.187 from the date of implementation. Technical conditions
This standard is proposed and managed by the National Technical Committee for Standardization of Hoisting Machinery. The responsible drafting unit of this standard is Dalian Daqi Group Co., Ltd. The main drafters of this standard are Zhou Yu'an and Cui Zhenyuan. 397
Mechanical Industry Standard of the People's Republic of China

Groove section
Casting sheaves for cranes--Groove profiles
This standard specifies the groove section dimensions and surface accuracy grades of cast sheaves for cranes. JB/T9005.1-1999
Replaces ZB J80 006.1-87
This standard is mainly applicable to cast wire rope sheaves for bridge cranes and gantry cranes (hereinafter referred to as sheaves). Sheaves for other cranes can also be used for reference.
The groove radius R of this standard is determined based on the maximum allowable deviation of the nominal diameter d of the wire rope of +7%. The maximum angle of deflection when the wire rope is wound into or out of the pulley groove (i.e. the angle between the center line of the wire rope and the plane perpendicular to the pulley axis) should not exceed 4°.

2The rope groove section is allowed to match according to JB/T9005.2, and the pulleys of the same diameter are made into types 3 according to the maximum rope diameter. The reference size is proposed for cast iron pulleys. 3.2 The surface roughness of the pulley rope groove is divided into two levels: Level 1: Ru6.3μm;
Level 2: Ral2.5μm.
3.3 Marking example
The radius of the pulley rope groove R is 13.5mm. The rope groove section with a surface roughness of level 2 is marked as: Rope groove section 13.5-2JB/T9005.1--1999400Www.bzxZ.net
