JB/T9006.1---1999
This standard adopts DIN15061-2:1982 "Cranes of steel wire rope drum groove section" in a non-equivalent manner.
This standard is a revision of 2BJ80007.1-87 "Diameter and groove shape of cast drum for crane". During the revision, the original standard was edited, and the main technical content remained unchanged. This standard is part of the JB/T9006 series of standards for "Casting Reels for Cranes", which includes the following three parts: JB/T9006.1-1999
JB/T9006.2--1999

Replaces ZBJ80007.1-87
The grooves specified in this standard are applicable to all cranes' cast drums and welded drums (hereinafter referred to as drums) except for multi-layer winding and electric hoist drums
The groove bottom radius R of this standard is determined based on the maximum allowable deviation of the nominal diameter d of the wire rope of +7%. When the wire rope is wound into or out of the drum, the angle of its deviation from each side of the spiral groove should not be greater than 1°. 2 Referenced standards
The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard was published, the versions shown were all valid. All standards are subject to revision, and parties using this standard should explore the possibility of using the latest versions of the following standards. GB/T1031--1995 Surface roughness parameters and their values ​​GB/T8918-1996 Wire rope
3 Drum diameter
The drum diameter D generally adopts the values ​​in Table 1. Table 1
4 Drum shape
The drum groove is divided into standard groove and deepened groove. The dimensions are detailed in Figure 1, Figure 2 and Table 2. The surface roughness Ra value of the groove is divided into two levels: Level 1: 6.3μm; Level 2: 12.5μm. Marking example:
a) The groove bottom radius R=10mm, the groove pitch P, =20mm, and the standard groove with a surface accuracy of level 1 are marked as: groove 10X20—1 JB/T9006.1-1999b) The groove bottom radius R of the drum groove is 10mm, the groove distance P is -24mm, and the surface accuracy is level 2. The deepened groove is marked as: Deep groove 10×24-2JB/T9006.1--1999Approved by the State Machinery Industry Bureau on June 28, 1999Implementation on January 1, 2000
