The model AZ1040 drive is the latest extension to the Amacoil-Uhing line of timing belt drives used for smooth linear motion in positioning and indexing applications. The drive features a one-piece aluminum profile extrusion that serves as the belt housing. T-slots and receiver grooves for the load carriage guide bars are incorporated into the profile design. The one-piece construction allows for longer, sag-free stroke lengths without needing scaling up to a larger drive size. In cross-section, the profile reveals a crisscross structural pattern, which also increases sag resistance and overall durability.
The belt pulleys are built into the AZ1040 end caps. T-slots are designed into the end caps to provide more options for mounting and integration with other assembly components. The load carriage measures 188 mm by 160 mm (7.4 inches by 6.3 inches) and has pre-drilled and tapped payload mounting holes as well as T-slots running parallel to the line of travel. The maximum travel speed is up to 5.0 meters/second (16.4 ft/sec), depending on the weight of the payload, which affects required drive torque and acceleration capability. The drive has a repeatability of +/- 0.2 mm (.008 inches) over travel spans of up to 2,000 mm (6.5 feet).
The AZ1040 timing belts are made of a heavy-duty synthetic rubber with a built-in steel cord strengthener. Several profile sections can by joined to accommodate long travel requirements.
