Rydell Industrial launches Linear Motion Drive Belting

admin — Fri, 19 Nov 2010 13:18:12 +0000

Rydell Industrial (Belting) Co. (www.rydell.com.au) is proud to announce the release of Gates open length synchronous belting (Gates Linear Drive Belting), which is designed for a wider range of robotics and linear motion applications.

Aside from long length AT5, AT10 as well as other steel reinforced belts, Rydell Industrial stocks Gates PolyChain GT Carbon belting, which is ideal for indexing applications thanks to its extremely high modulus carbon fiber reinforcement.

Positioning applications such as ball screws and X/Y tables that use synchronous belt drives completely rely on positioning accuracy and smooth operation. Thus, belt design engineers should take into account any elongation of the belt under load.

Low stretch linear motion belts including PolyChain are well-suited for positioning applications. Belt elongation under load within the range of half a millimeter per meter of belt length (0.05 percent) is easily achieved. A 37 mm standard belt width is rated to a minimum breaking tension of over 42,000 N.

Rydell Industrial (Belting) Co offers a free design engineering service, as well as onsite drive analysis and troubleshooting of linear motion drive belting applications.

The company also supplies drive hardware for linear motion drives including bushings, pulleys, tooth clamping plates and idlers as part of a comprehensive belt drive package.

New Timing Belt Drive Resists Sag over Long Travel

admin — Wed, 07 Apr 2010 19:01:09 +0000

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.

HepcoMotion® PDU2M Belt Driven Unit from Bishop-Wisecarver

admin — Wed, 10 Mar 2010 15:53:44 +0000

Pittsburg, CA – - Bishop-Wisecarver Corporation announces the availability of the new HepcoMotion® PDU2M Profile Belt Driven Unit, a high capacity version of the successful PDU2. The PDU2M incorporates a carriage that contains four extra rollers on each side in order to withstand increased moment forces. Suitable for demanding single-axis systems and multi-axis applications, the PDU2M delivers a 50% higher load capacity, a 200% increase in moment load capacity and a 1,000% improvement in moment load stiffness compared to the standard PDU2. Designers can now specify a single PDU2M unit as a horizontal axis in an X-Z system, where previously two PDU2 units working in parallel would have been required to provide the necessary rigidity and strength.

PDU2M is comprised of a rigid but lightweight aluminum slotted profile fitted with a toothed belt drive and carriage which effectively encloses the unit. Rated for operating speeds up to 6m/s and loads up to 750N, PDU2M’s 20AT3 belt allows for driving forces up to 280N. Left, right or double drive shafts can be specified together with a range of options such as brakes, positioning encoders and mechanical or inductive limit switches. Internal bumpers provide end of stroke protection at both ends.

Key to this unit is the extra ultra-high performance HepcoMotion Herculane® wheels that are mounted on adjustable eccentric studs. These wheels run virtually friction-free on the inside of the profile providing stable support for the carriage plate; felt wipers sweep debris from their path. Several carriage styles are available to allow for quick and easy construction of multi-axis systems with minimal brackets and hardware.

PDU2 is fully compatible with aluminum profile systems (which Bishop-Wisecarver carries) and is an ideal replacement for failing ball-based systems that are unable to match its speed and reliability.

EXCEL-A-BELT Miniature Drive Belt System

Editor — Mon, 20 Apr 2009 18:29:52 +0000

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.
