3 Pulley
3.1 Groove size and tolerance
The groove size shall comply with Table 1 (see Figure 1, Figure 2).
4.2.1.1 Two measuring pulleys of equal diameter, one of which is stationary,
and the other is movable along the track. Its recommended effective diameter
groove sizes.
4.2.1.2 Measuring force application device. used for applying a measuring
force on a movable pulley.
4.2.1.3 Center distance measuring device. used to measure the distance
between the two pulley centers.
4.2.2 Measuring force
See Table 4 for the measuring force used to measure the effective length of
the belt.
Table 4 -- Measuring pulley parameters and measuring force
Pulley effective circumference (at effective diameter) Ce / mm 300
Pulley diameter at outer edge of testing ball or column K / mm 96.48 ± 0.13
Measuring force per wedge F / N 100
4.2.3 Measurement procedures
When measuring the effective length of the belt, it shall mount the pulley to
the measuring device first. After applying the specified measuring force, the
belt is rotated over at least two turns so that it wedges well into the pulley and
evenly distributes the total measuring force across the two straight sections of
the belt. Then measure the center distance between the two pulleys.
height of the belt according to formula (2).
where,
Le - effective length of belt, in millimeters (mm);
Ce - effective circumference of testing pulley, in millimeters (mm);
amax - maximum measured value of pulley center distance, in millimeters
(mm);
amin - minimum measured value of pulley center distance, in millimeters (mm).
