BKL-DOUBLEFLEX -

Shaft misalignment is virtually unavoidable in most machine design. Tolerance stack-up in machined interfaces between motor frames, gearboxes, actuators, ball screws, etc, will normally result in slight misalignment between the driving and driven shafts in the lateral and angular directions. While most motor mounting brackets allow for sufficient alignment to accommodate single-flex bellows couplings, occasionally a given machine layout will require flexible couplings to accommodate more than just a few thousandths of an inch of shaft offset. For this purpose R+W has recently released a special series of double flex bellows couplings.

The BKL-DOUBLEFLEX allows for a multiplication of the allowable lateral misalignment by taking advantage of the greater flexibility in the angular direction of each bellows. Compared to their single-flex counterparts, the BKL-DOUBLEFLEX allows for up to 5 times more lateral misalignment depending on the size. Additionally the angular and axial misalignment ratings are doubled, allowing for easy absorption of shaft expansion. Compared to other types of flexible couplings, the BKL-DOUBLEFLEX possesses a high level of torsional stiffness, a low moment of inertia, and only light restoring loads on shaft bearings. Special miniature versions are available for encoders and stepper motors.

The BKL-DOUBLEFLEX is currently available in torque ratings from 15 – 500 Nm (132– 4425 in-lbs.) and can accept English or metric shafts from 8 – 62 mm (5/16” – 2-5/16” in.).

Unidrive SP Size Zero is a new member of the Panel Mount range. It reduces the drive size by 60% for motors from 0.5 hp to 2 hp. The new model has the same parameter set, universal motor control and user interface as the rest of the Unidrive SP range.

For details download the new Unidrive SP brochure or the Unidrive SP size 0 flyer.

By sensing motor current, brushless servo technology can measure motor current to an accuracy of about 10%. This equates to torque measurement in a rotary servo motor and force in a linear servo actuator.  When your application requires higher accuracy, Exlar offers load cell technology embedded in the GSX30, 40 & 50 and I 30 & 40 actuators.  The load cell is a strain gauge type, offering you stable and accurate load sensing in both the tension and compression directions, and for static or dynamic loads +/- 1%. The packaging of the strain gauges are integral to the actuators housing offering a compact, protected, and robust design.

Applications that utilize load sensing include but are not limited to:

Fastening and Joining |  Riveting |  Bag Sealing |  Thermoforming |  Injection Molding | Precision Pressing |  Fillers |  Formers |  Precision Grinders |  Clamping |  Die Cutters |  Lifts |  Molding |  Welding |  Tube Bending |  Stamping |  Test Stands |  Tension Control | Wire Winding |  Parts Clamping |  Dispensers |  Interference Detection

The Right Miniature Optical Sensor - for Your Application Too

Features and benefits
• Smallest fiber-optic sensor
• Large selection of fiber-optics
• Round and linear beam shapes
• Fixed sensing distances
• Efficient background suppression
• Simple mounting Different technologies - one

With its wide range of LED and laser sensors, the successful Series 10 is to be extended by several extremely interesting variants. Baumer offers new sensors with different beam shapes. Three different spot-shaped beams (diameters 0,1 mm, 2 mm and 4 mm) permit the detection of objects of different sizes. In contrast, circuit boards with milled grooves and drilled holes can be reliably detected by a linear beam. A narrow laser and a linear LED version are now available. Fixed, precise sensing distances (30 mm, 50 mm or 80 mm) and background suppression are features of the FHDK 10 diffuse sensor. The advantage: adjustment is unnecessary and undesirable misadjustment is impossible. The sensor range is completed by the fiber-optic sensor FVDK 10. As all sensors of Series 10, the fiber-optic sensor also features simple operation and installation. Together with the wide Baumer range of fiber-optic devices, even the most difficult applications can be mastered.

Three Technologies -- One Actuator

Exlar's Tritex^TM Series actuators combine three technologies to deliver for the first time a truly simple and low cost electric alternative for fluid power actuators. Tritex actuators with built-in mechanical converters also replace electric drive systems employing ball screw or gear reducer mechanisms for a complete actuation solution.

Tritex actuators represent an all-electric actuator solution for moving and/or positioning mechanical devices in a large variety of industrial or military grade applications. Tritex actuators eliminate the need for pneumatic and hydraulic cylinders while improving position performance, reducing cycle times and eliminating the maintenance associated with fluid power devices. Ball screw mechanisms, and separately mounted gear reducers are also a thing of the past because rotary to linear converters or mechanical reducers are designed in.

Less is More

The Tritex Series of electric actuators combine a brushless servo motor, servo amplifier and position controller in a single industrial grade enclosure. This eliminates both the external servo amplifier and the expensive and failure prone cables associated with a typical servo system. Component selection, design and installation are completely eliminated. Trouble-shooting and debugging of individual components; gear reducers, rotary-to-linear converter mechanisms and the complex wiring layout typical of such a system are gone. The panel space for a separately mounted amplifier and installation of that amplifier are no longer necessary.

Linear Applications

Tritex linear actuators employ Exlar's patented, inverted roller screw mechanism for converting the rotational motion generated within the Tritex actuator to the highly robust and long-life linear motion required to solve applciations that previously required pneumatic or hydraulic cylinders. No additional mechanisms (such as ball screws) are required to convert the actuator's rotary power to linear motion.

The Tritex linear actuator contains the same control capability of the Tritex rotary acctuator. In addition, the Tritex software allows you to create a sequence which causes the actuator, when commanded, to move forward while pressing an object into position. You can establish a pre-programmed force which triggers an event (such as stopping or retracting to another position) or it can maintain that force level until commanded otherwise. The sequence is ideal for assembly, test, and pressing applications.

As with the rotary Tritex, the linear Tritex can be programmed to follow an analog command signal, making it ideal for controlling valves and dampers in process control applications.

Three functional Configurations

Base: Epsilon EP-B

The EP-B drive is ideal for servo applications utilizing an analog command signal and position feedback reference. The drive can be configured into five operating modes: Analog Torque, Analog Velocity; Preset Velocity; Pulse follower, or Analog Position. The EP-B has the unique capability of combining an analog command with a preset velocity to create a new command for trimming or advance/retard operations. The EP-B drive is an excellent choice for stepper replacements or low cost control systems.

Indexer: Epsilon EP-I or EP-IDN

The EP-I drive is a highly capable position controller that provides Home, Index, and Jog motion profiles. The EP-I holds up to 16 unique indexes that also can be chained together to create complex motion profiles. The powerful Homing function of the EP-I provides the ultimate in flexibility without sacrificing ease-of-use. Best of all, the EP-I has a unique alternate mode feature whereby the EP-I drive can perform an Index or Home function, and then switch to an alternate mode such as analog toque, analog velocity, or pulse follower mode on the fly! The EP-I can solve countless applications in this very compact cost effective package.

Programming: Epsilon EP-P

The EP-P drive provides the highest level of control by allowing the user to create complete user programs to sequence the motion control along with other machine functionality. The EP-P can be used to solve the most complex motion applications and still be easy-to-use because of the PowerTools Pro configuration software. PowerTools Pro uses simple drag-and-drop and fill in the blank screens that make setup a snap. User programs are created using a text based motion language that is as easy to read as it is to program. If you don't know the command, just drag it in from the drop down box and PowerTools Pro will assist you with the syntax. With intuitive software and plenty of online help, programming this servo drive is easy; in fact it is “Motion Made Easy!”
