PU timing belt T2.5 880 - Megadyne Megapower

PU timing belt T2.5 880 – timing belt for synchronous power transmission

PU timing belt T2.5 880 - Megadyne Megapower is a Megadyne Megapower timing belt in polyurethane. It has a T2.5 profile, 880 mm pitch length and 352 teeth, and it is intended for belt drives where the belt and timing belt pulley must follow each other without slip.

The pitch length is the length of the belt measured along the pitch line. Together with the tooth pitch and the number of teeth, it describes the synchronous dimensions of the belt in the drive.

With 352 teeth and 2.5 mm tooth pitch, the pitch length of 880 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

The T2.5 profile has a 2.5 mm tooth pitch and belongs to the small metric T profiles. It is often used in compact synchronous belt drives where the belt must follow the timing pulley precisely over shorter lengths.

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.

Polyurethane and steel cord

The construction consists of polyurethane and zinc-coated steel cord. The polyurethane forms the teeth and spine, while the steel cord contributes to low elongation and stable pitch length.

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.

Operation with timing belt pulleys

The synchronous function comes from the tooth shape. When the belt and timing pulley fit together, the movement is maintained mechanically instead of relying on friction alone.

The standard widths for this belt are stated in the technical data. The width does not change the tooth pitch, but is part of the overall dimensions of the belt in the drive.

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.
