Pulley Description
72 L 100 (Type 3A) TB 2012 (Cast Iron) is a basic type of pulley for belts with trapeziodal L profile. It is made of grey cast iron. Its design is based on the ISO 5294 standard.
The pulleys are mounted on shafts using the Taper Lock bushes (TB 2012), thanks to which there is not only a fixing on the shaft with a keyway, but also an axial locking against displacement.
Pulley Fields of Use
The L Taper timing pulleys are designed for all types of L belts with pitch 9.525 mm.
They are typically used in older machines with lower and medium performance, for example in packaging machines, in the ceramic, textile, food and tobacco industry and in many other machines. In new applications, they are often replaced by HTDHigh Torque Drive
Because of its tooth height and semi-circular tooth geometry, the HTD profile is especially good at avoiding jump-over of the teeth in operation. The HTD profile is extremely suitable for transmitting high torques., STDSuper Torque Drive
The involute shape of the STD profile allows optimal tooth engagement with the pulley. As a result, it provides precise and quiet operation even at high belt speeds. or CTDConti Torque Drive
The CTD profile is a symbiosis of the HTD and STD profiles, combining the benefits of both tooth geometries. The tooth height and width correspond to that of the HTD profile for transmitting extremely high torques and preventing jump-over at the same time, while the involute-shaped flank ensures very smooth running. profiles.
