Ondrives Introduces Compact Spur Offset Gearboxes

Ondrives had introduced a slimline version of its spur offset gearboxes for spring 2011. 'These units have been designed for those applications where a smaller space envelope means a slimmer unit must be used,' said Ben Hinchliffe, the company's managing director. The smaller gear reducer units are, on average, 15 per cent slimmer than their standard counterparts, offering exactly the same torques, efficiencies and speeds as the bulkier versions, making them suitable for applications that need optimum output in a smaller unit.

This has been achieved by the smaller units having a flush bore output and the larger sizes being bore input instead of shaft input. All are made in house by Ondrives using the latest CNC technology in a purpose-built environment, according to sales manager Barbara Fisher. Specials can be quoted for where required and modifications can be incorporated into standard designs.

Sphere Detectors Optimise Measurement of Light

Newport has enhanced its calibrated integrating sphere detectors, which are designed to measure the output light power of high-power light sources. These spheres optimise the measurement geometry for laser beams and other light sources, whether collimated or divergent.

To accommodate various power-range requirements, the calibrated integrating spheres are available in 2in, 3.3in and 5.3in diameters. The new design includes a robust port frame, as well as a variety of attachments and accessories to provide greater configuration flexibil…

Tool Monitors Temperature and Reports Back by SMS

The AGT GSM temperature monitor is a remote-controlled device that can monitor temperature and report back by SMS text message or by email. It will respond with the current temperature when sent a text message and will automatically send warnings when preset temperature limits are exceeded. In addition, it has a 'ring out' mode, where it will dial up to 10 telephone numbers to 'ring the phone'.

The incoming caller ID tells the receiver that the AGT is calling with a temperature issue. The temperature sensor is digital and operates via a built-in RS232 port. The unit is powered from a 5-15VDC supply via a supplied mains adaptor, incorporates a global GSM/GPRS engine and needs only a SIM card and a GSM signal to operate. The operating temperature range is -30C to +75C.

The AGT can be programmed to log the temperature data at preset intervals and then to email the data log as a .CSV file once an hour. Applications include building management and automation and monitoring …

Laser Components Offers Small Laser Modules

The small coaxially aligned LC-LMD-650-12 laser modules are available as part of Laser Components' LMD low-cost laser module series. While the housing and the beam axis of standard products often differ by several degrees, the maximum angular error of the LC-LMD-650-12 modules is +/-0.05deg. This property speeds up assembly time. In light curtains, for example, each module no longer has to be aligned to match the photocell on the opposite side.

It is usually enough to position the module mount once. The laser modules then only have to be placed into the mount and soldered. The lasers also feature small dimensions. They have a length of 15.50 +/-0.05mm; the diameter is 10.00 +/-0.05mm. This type of module is available with an output power of less than 1mW and less than 5mW. The wavelength is 650nm and the operating voltage is 3V DC.

Liquid Cooling Package can be Easily Retrofitted

Rittal's new LCP Extend is a liquid cooling package unit based on an air/water heat exchanger that solves the problem of high heat losses caused by Blade and 1U servers of up to 12kW per rack. Without having to modify the existing series of enclosures, this product can be attached as an independent cooling unit to the rear doors of practically any rack while the rack is in operation.

This means the system can be easily retrofitted in the event of any problems from thermal issue. Hot air, dissipated towards the rear by the servers, is forced through the air/water heat exchanger by fan units and then expelled. Maximising long-term energy costs is also essential, therefore the LCP extend can be connected to a free-cooling chiller circuit, which provides continuous cooling at minimal costs.

Couplings Stop Failure of Underground Mine Trucks

A large construction and mining company has purchased couplings from Renold to provide a long-term solution to eliminate the constant failure of couplings on its underground mine trucks. For many years, the company was fitting V-type rubber-in-shear couplings between the engine and the gearbox. However, when the coupling failed, the truck was coming to a complete stop, often blocking an important access point. Renold recommended the HTB 4500 rubber-in-compression coupling.

Its intrinsically failsafe, maintenance-free and severe shock load protection properties, coupled with its high temperature capability of up to 200C, made it a suitable choice. A rubber-in-compression coupling was also favoured by the company as it can drive metal to metal to move the truck out of the way and continue mining if the rubber blocks disintegrate. This was illustrated when a problem with the oil circulation in the gearbox resulted in the gearbox overheating and destroying the rubber blocks in the couplin…

Fast and Accurate Balance for Grading Grain

Mettler-Toledo, a supplier of precision instruments, offers the Newclassic MS as a durable, high-performance balance that helps grain operators acheive both accuracy and speed. This benefits not only buyers but also farmers, who are paid based on crop quality. Harvest is a busy time at grain-receiving sites and testers must work quickly, often in extreme conditions, to expedite offloading and reduce related operating costs. But in addition to speed, assuring grain quality is paramount to ensure the integrity of the international food supply chain.

Density, moisture content and protein quality must fall within certain tolerances to be accepted. Accurate grading produces more uniform flour and in the end, more satisfying bread and other cereal grain products. ISO 7971 specifies a multi-step routine for determining the bulk density or mass per hectolitre of grain samples. If any variable is off, an entire truckload may be deemed poor quality, resulting in expensive delays or even product…

THz Pulse Generation Kit Targeted at Researchers

Newport has introduced a terahertz (THz) pulse generation kit that uses a sub-35-fs Ti:sapphire amplifier system, designed for demanding applications by the research community. The kit can be integrated with a Ti:sapphire amplifier to generate terahertz pulses that can be further used for linear, non-linear and time-resolved spectroscopy applications. The THz pulse generation kit utilises standard Newport optics, opto-mechanics, manual stages and Conex-based motorised solutions to provide high performance and accuracy.

The 800nm Ti:sapphire laser pulse (1kHz ~ 300uJ per pulse) is focused into ambient air to generate the air plasma that produces THz pulses. With this design, the damage threshold is not a concern as the air replenishes itself from pulse to pulse. The generated THz pulse has the oscillation that spans about 1ps and has the estimated pulse energy of 0.1-0.3nJ per pulse. In addition, the ability to recover the phase and the amplitude information of the THz field through el…

Scout Device Helps to Spot Screw-Fastening Errors

The Scout screw counter from Mountz is designed to help manufacturers to detect and eliminate costly screw-fastening errors during the assembly process. Screw counters verify that all fasteners have been installed and were seated to the tool's preset torque setting. These units take the control of the assembly process out of the operator's hands. The Scout screw counter is designed to detect cross threading, omissions, unfinished rundowns and cycle completes, ensuring that the assembly process is done correctly the first time.

The Scout operates jointly with Mountz electric screwdrivers and STC30 or STC40 power supplies. With four ports on the side of the Scout, a maximum of four screwdrivers can share one program with the unit. The Scout can 'learn' the characteristics of not only the power tool but also that of the application that it is being used on. This allows the screw counter to distinguish between a fastener that was properly seated and one that was either str…

How to Maintain and Service Torque Wrenches

Mountz has released a whitepaper designed to help users to understand, maintain and service their torque wrenches. According to the company, a torque wrench is a precision tool and should be treated and maintained like a measuring instrument. A torque wrench must be properly calibrated and maintained on a preventative maintenance and calibration schedule. Mountz can help users to learn valuable information regarding setting verification and calibration intervals, as well as preventive maintenance for torque wrenches.

Users can also gain a better understanding of different torque accuracies listed by suppliers as well as understanding the scale used on different torque wrenches. In the maintenance and manufacturing world, tightening, controlling or measuring the torque of fasteners is imperative for production efficiency and quality control. With inadequate torque, a fastener can vibrate or work loose. Conversely, if the torque is too high, the fastener can break or strip or adjoining …

Trumpf Slat Cleaner Gets in Hard-to-Reach Spaces

Trumpf's new Trutool TSC100 slat cleaner is designed to remove accumulated slag resulting from stainless steel, mild steel or aluminium laser processing. It is said to be quick, clean, time saving and highly effective. Not only are the slats cleaned on the sides but also in the hard-to-reach spaces in between. The result is a clean flatbed laser machine. The Trutool TSC100 automatically adapts to different slag thicknesses and the operator can move the tool up to the pallet frame.

It is said to be easy to handle and can be comfortably operated by one person. On flatbed laser machines with a pallet changer, cleaning can be in parallel to production. According to the company, clean slats are important to the process stability of the laser cutting machine. If slag is allowed to build up, not only is the quality of the process compromised but so too is the quality of the finished part. As the Trutool TSC100 makes the job straightforward, there is no need to let this happen.

The slat c…

Tiger.tec Silver Inserts Increase Tool Life

Tooling company Walter claims that users of the Tiger.tec Silver inserts are realising tool life increases of 100 per cent. For example, machining a variety of workpieces at similar cutting data (feeds and speeds), the Walter Tiger.tec Silver insert achieved a 100 per cent increase in tool life when machining St52-2 guide tracks (using a Xtra.tec octagon cutter) and a 75 per cent increase in tool life on the face milling of GGG50 brake callipers using a Xtra.tec shoulder mill.

Tiger.tec Silver features a surface treatment that significantly reduces the in-cycle machining stresses of both wet and dry applications, thanks to its balanced combination of a high level of toughness and maximised hardness.
