4 Types and basic parameters
4.1 Typical structure
The typical structure of a sheave for hoisting appliances (hereinafter referred to as "sheave") is shown in Figure 1.
4.2 Types
4.2.1 According to the manufacturing process, sheaves are classified as follows (typical schematic diagrams are shown in Figure 2):
a) Cast sheaves;
b) Welded sheaves;
c) Double web pressed sheaves;
d) Rolled sheaves.
4.2.2 According to the type of bearing used, sheaves are classified as follows (typical schematic diagrams are shown in Figure 3):
a) Deep groove ball bearing type;
b) Cylindrical roller bearing type;
c) Double row full complement cylindrical roller bearing type;
d) Plain bearing type.
4.3 Basic parameters
The basic dimensions of the sheave rope groove cross section shall comply with Table 1. The schematic diagram is shown in Figure 2.
The hub dimensions and other detailed dimensions shall be determined by the sheave manufacturer based on the shaft dimensions, the bearing type, and the forces and strength of the sheave.
The sheave shaft diameter should be selected from the following series (in millimetres): 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 220, 240.
5 Selection series and matching of sheave diameter and wire rope diameter
The matching relationship between the sheave diameter D and the nominal diameter d of the wire rope is shown in Table 2. The area enclosed by the black frame line in the table is the most commonly used matching range.
