PU timing belt T2.5 620 - Megadyne Megapower

PU timing belt T2.5 620 – T2.5 timing belt from Megadyne

PU timing belt T2.5 620 - Megadyne Megapower is a cast endless Megapower PU timing belt with T2.5 profile. The length along the pitch line is 620 mm and the number of teeth is 248. The belt transmits power via tooth meshing and is used in synchronous technical drives.

The most important measurements for the belt are profile, pitch length, tooth pitch, number of teeth and width. When these measurements match the timing belt pulley, the belt will have a clean tooth mesh and a stable operation in the drive.

With 248 teeth and a 2.5 mm tooth pitch, the pitch length of 620 mm matches the belt's synchronous dimensions. The pitch length describes the belt's turn along the pitch line and is the length used in conjunction with the tooth pitch and number of teeth.

The width tolerance is +/- 0.30 mm, the thickness tolerance is +/- 0.15 mm, and the sleeve width tolerance is +/- 10 mm. The working temperature for standard Megapower is -25 °C to +80 °C.

T2.5 profile and tooth pitch

T2.5 is a metric T-profile with a fine tooth pitch of 2.5 mm. The small pitch makes the profile suitable for smaller pulleys and precise movements when the drive is built for T2.5.

T2.5 is a T-profile and should be kept separate from other profiles with the same pitch. A T2.5 belt should run in timing belt pulleys where the tooth shape matches this particular profile.

Material and construction

The Megapower belt is made of polyurethane with steel cord inside the belt. The steel cord is the tensile element and helps to limit unwanted elongation.

The molded endless design provides a continuous belt without joints. This is an important difference compared to open or joined belts because the belt is made as one closed length from the start.

The standard version is thermoset polyurethane, standard 88 ShA with zinc-coated steel cord. The steel cord is located inside the belt and helps to keep the pitch length stable when the belt is operating in a synchronous drive.

Tooth engagement in operation

The force is transmitted through the timing mesh. Therefore, the belt must be used with timing belt pulleys of the same profile and with a belt width that is suitable for the load and structure of the drive.

The width is part of the overall dimensions of the belt. A narrower and a wider belt in the same profile can have the same pitch length and number of teeth, but they must match the actual belt routing.

For this T2.5 belt, the standard widths are 4, 6, 8, 10 and 12 mm. The width does not change the tooth profile, but it must fit the timing belt pulley, pulleybase and the space the belt has in the machine.
