Safe and accurate transmission of torques is essential for precision drives of cross cutters. This is ensured by the use of steel bellows couplings with force-fitted shaft-hub connection.

The metal bellows couplings of the KXL series from Jakob Antriebstechnik were designed for medium and large drives up to a maximum of 65,000 Nm. A special design feature is the three-piece design with a flexible bellows package as an intermediate piece. This removable intermediate piece, consisting of an optimized, torsionally stiff stainless steel bellows with 2 bellows shafts per side and a variable length intermediate pipe, is frictionally connected (screws ISO 4017 / 10.9) with the two hubs. This results in a considerable ease of assembly, as e.g. can be omitted in the maintenance or service case a costly disassembly of the heavy drive or driven units. The designer has several hub variants available for the specific application. The extremely favorable moment of inertia and the rotationally symmetric design ensure good dynamic performance. The KXL couplings are particularly suitable for precise drives, such as for printing presses, cross cutters, main spindle drives, transfer axes or transmission connections. A media transport or a parallel drive train through the coupling interior is basically possible. The connection to the shafts can be done either as a conical clamping ring hub or as a flange hub.

Hub Type A

Frictional, backlash-free conical clamping ring connection – outside – bellows package radially freely removable. For the overall length “L4”, the axial lengthening of the bellows package of 4 mm is already taken into consideration during assembly.

Hub type B

Frictional, backlash-free conical clamping ring connection – internal bellows package radial NOT freely removable.

Hub Type F / G

Mounting flange according to ISO 9409 or customer specification – centering outside or inside. Dimensions of flange hub F and G of L13, L19 and D6, D9, D10, D11, D12 according to customer specifications.

Hub Type A / B

Frictional, backlash-free conical clamping ring connection – outside / inside. Bellows package radially NOT freely expandable

Power Supply Product 1U half-rack programmable DC power supplies deliver 1,500W
Picture: TDK

TDK Corporation (TSE 6762) announces the introduction of the GH1.5kW series of 1,500W rated, 1U high half-rack wide, programmable DC power supplies. This latest extension to the TDK-Lambda Genesys+ series has the same functionality and programming as the standard full rack 1.7kW to 15kW models. Applications include bench-top or rack mount laboratory use as well as component, automotive and aerospace testing, semiconductor fabrication, solar array and battery simulation, plating and water treatment.

Ten models are available rated at 0V to 10V, 20V, 30V, 40V, 60V, 80V, 100V, 150V, 300V and 600V, with output currents of 0-2.6A to 0-150A. All models are capable of operating in constant voltage, constant current and constant power modes. Up to four power supplies can be connected in parallel with an advanced master/slave system that provides dynamic load response and ripple and noise characteristics comparable with that of a single power supply. The input voltage range is 85 to 265Vac facilitating global use.

Excluding the busbars, the GH1.5kW measures 214mm wide, 43.6mm (1U) high and 441.5mm deep. Two units can be mounted side by side in a standard 19” rack, with the GH/RM option kit. The Genesys+ half rack units weigh less than 3.5kg for easy movement or installation. A blank front panel option (with no metering or control functions) is available where user access is not required or needs to be restricted. Snap-on dust filters can also be added to restrict airborne contamination.

Programming is standardised across the Genesys+ series by either utilising the front panel controls, remotely via LAN (LXI 1.5), USB 2.0 and RS232/485 communications, or by using the isolated analogue control and monitoring (0-5V, 0-10V) which are provided as standard. Optional interfaces include a choice of GPIB (IEEE488.2) and the Anybus CompactCom interface platform for EtherCAT, Modbus-TCP and other interface options as they are released. Software drivers, a waveform creator and a virtual front panel GUI are provided in the software package. Safety features are standard in all GENESYS+™ power supplies, providing Safe/Auto Re-Start, Last Setting Memory and built-in protection functions. Control of voltage and current slew rate, internal resistance simulation and display brightness control are all standard features.

The five year warranty series is safety certified to IEC/EN/UL 60950-1 (61010-1 pending), is CE marked to the Low Voltage, EMC and RoHS Directives and is compliant to the industrial IEC/EN 61203-3 standard for conducted EMI, radiated EMI and EMC immunity.

The Fritsch Analysette 28 ImageSizer for dry and wet measurement is the ideal Particle Sizer for all applications that require accurate and reproducible measuring results for both particle shape and size. The optical process of Dynamic Image Analysis provides results for a wide measuring range, delivers multiple shape parameters and evaluation possibilities for particle size. The measuring time depending on the sample quantity, is under 5 minutes. And the result is available immediately.

Your advantage: Great flexibility for different measurement tasks for particle sizes of 20 µm – 20 mm in quality control, research and laboratory – and is a very easy and cost-effective alternative to sieving.

Easy wet measurement of suspensions and emulsions

The Analysette 28 ImageSizer is in combination with the corresponding wet dispersion unit ideal for measurement of particle shape and size of suspensions and emulsions.

Wet dispersion is particularly suitable for fine particles, poorly flowing, fine-agglomerating or sticky materials, which do not react in water or other liquids.

Your advantages

  • Extra wide measuring range of 20 μm – 2.8 mm
  • Strong, freely adjustable ultrasonic power for deagglomeration
  • Extremely quiet dispersion with strong pumping power
  • Benzine, alcohol and many organic solvents can also be used as suspension liquid as a standard feature
  • Automatic rinsing cycle
  • No dead space in measuring and rinsing circulation system
  • Fast and consistent cleaning

Efficient dry measurement of powders and bulk solids

The Analysette 28 ImageSizer is the ideal Particle Sizer for fast analysis of particle shape and size of dry, free-flowing materials. Via the optical analysis of the particle shape and particle size, you can identify damaged particles, contaminates, agglomerates or oversized and undersized particles accurately and fast and view them completely uncomplicated in single images.

Your advantages

  • Extra wide measuring range of 20 μm – 20 mm, individually adjustable
  • 3 telecentric lenses are available
  • Up to 75 images per second
  • Agglomerates are preserved

State-of-the-art, simple and fast evaluation via Cloud and Gallery

The evaluation of the measuring results is uniquely simple with the Analysette 28 ImageSizer. The evaluation software ISS displays each recorded particle clearly as a data point in the immediately available Fritsch Cloud as well as in the Fritsch Gallery. You freely choose which statement is of interest to you: for example the Sphericity in regards to the Minimum Feret Diameter, the aspect ratio, applied on the porosity, or the convexity as a function of the particle Cross Section. Or display the particle size distribution as a cumulative curve, as a bar chart or in a table form.

Each particle can be clicked individually

The state-of-the-art of uncomplicated evaluation: For fast single image viewing, each individual particle can be opened directly with a mouse click from the clearly arranged Fritsch Cloud. The really important information for you about the morphology will be shown by the position of the data point in the Cloud. Without time-consuming search, you can immediately analyse, evaluate and delete individual selected particles. All available size and shape parameters are automatically displayed.
