New Timing Belt Drive Resists Sag over Long Travel

Aston, PA – The new model AZ1040 drive is the most recent 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 which 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 permits longer, sag-free stroke lengths without necessitating scaling up to a larger size drive. In cross-section, the profile reveals a dynamic crisscross structural pattern which further increases sag resistance and overall durability.
Belt pulleys are built-in to the AZ1040 end caps. T-slots are also designed into the end caps which provide more options for mounting and integration with other assembly components. The load carriage measures 188 mm x 160 mm (7.4″ x 6.3″) and has pre-drilled and tapped payload mounting holes, and also T-slots running parallel to the line of travel. Maximum travel speed is up to 5.0 meters/second (16.4 ft/sec) depending on the weight of the payload which will also affect required drive torque and acceleration capability. The drive has a repeatability of +/- 0.2 mm (0.008″) over travel spans of up to 2,000 mm (6.5 ft).
Amacoil-Uhing AZ1040 timing belts are made of a heavy-duty synthetic rubber with a built-in steel cord strengthener. Multiple profile sections may be joined to accommodate long travel requirements. Five different AZ models are offered all of which are distributed in the USA by Amacoil, Inc. who also handles parts, repairs and technical support for Uhing linear drive products.

EXCEL-A-BELT Miniature Drive Belt System
Something new in the miniature drive belt system from NBK. After years of testing, NBK’s system offers a unique arched tooth profile with zero backlash which enables the system to run longer, cleaner, and quieter than common drive belts in use today.
The key to the new tooth profile, which allows for high accuracy positioning and precise rotation transmission, is that it provides a rolling action between the belt and the specially formed drive sprocket. As the belt tooth enters and leaves the sprocket it does so in a rocking motion which reduces wear and contaminates from belt or sprocket tooth abrasion.
The drive sprockets have bore sizes ranging from 3-25mm and PD’s of 17-54mm and come standard for shaft clamping. Four belt widths of 3, 4, 6, and 9mm are available. Excel-A-Belt miniature drive system is perfectly suited for use with motors of 10-1,000W.

New Hyde Park, NY – Techno, Inc. Linear Motion Systems is proud to announce the ZF1 Belt Drive Slide, a low cost, economical slide that can lower your costs in factory automation applications. This lightweight model is driven by a 9 mm wide HTD belt that can be ordered in travels ranging from 153 mm (6”) through 2853 mm (112.3”). Perfect for tight spaces, the ZF1 Belt Drive Slide is 30 mm wide with an accompanying carriage that is 72 mm wide. The small width of the slide allows it to fit into tight spaces, increasing the versatility and options any machine builder might need in their design.
Techno’s ZF1 Belt Drive Slides have a maximum speed of 1.5 m/sec., and can be ordered with a 200W (2:1 Ratio), 100W (2:1 Ratio) servomotors, 50 N•cm, 160 N•cm (2:1 Ratio) stepper motors, or a 2:1 Ratio Assembly with no motor. The belt drive pulley is 19.1 mm in diameter and has a specific mass of 0.0225 kg/m.

New Belt Driven Actuator from PBC Linear

Rockford, IL – PBC Linear has expanded the PL series product line by introducing the belt driven PLB actuating system. With its inherent lightweight design, the PLB actuator provides easy installation for long-lasting linear motion. Built for high speed and load applications, the PLB actuator features Integral V™ guided cam rollers, SIMO™ precision machining (Simultaneous Integral Milling Operation), a robust housing system, and a wide range of optional accessories.
The PLB actuator houses patent pending Integral V Technology (IVT) steel raceways to guide the rollers. First introduced in 2008, IVT’s innovative design allows for high accuracy with fewer mounting components at no added cost. Backed by IVT, this cam rolling system not only provides accuracy (within .1mm/m), but supports the steel-reinforced belt for high speed (10 m/s) and high acceleration travel—giving the PLB actuating system a boost over the competition both in price and performance.
In order to further ensure precision linear motion, the entire outer-housing of the PLB has been machined with PBC Linear’s newly developed SIMO process. Concurrently milling on all sides of the actuator simultaneously, PBC Linear can provide highly accurate surfaces with tighter tolerances spared the expense. Composed of anodized aluminum, the outer housing of the PLB also tolerates corrosive environments.This allows for the PLB linear actuator to be both an economical and durable choice when selecting a linear motion solution.
Available with optional dual carriage design, clamps, limit switches, and shaft extensions, the PLB linear actuator can be customized to meet virtually any linear motion solution; such as wash down, clean-room, long travel length, multiple carriage.
