Nevertheless, such a compensating coupling offers a performance that one might not expect from its tiny size. Their outer diameter can be compared to that of a ladybug and with their bore diameter they would fit into a larger spaghetti.

Such a miniature Compensating coupling is located, for example, in systems for conveying and metering extremely fine media quantities Microdosing pumps. They are also used in systems for the assembly or encapsulation of miniature components or in Microsystems for the production of the smallest optics. For such applications, Orbit Antriebstechnik offers corresponding compensating couplings with the smallest outer diameter of 5,9 to 9,9 mm with a bore diameter of 1 to 4 mm.

The range of such micro couplings includes a wide variety of technical features that one optimal shaft connection guaranteed for specific application profiles.

They can be used to dose very precisely small quantities of liquid media. The is aligned with the liquid to be dosed material selected for the parts in contact with the media.

The shaft coupling is suitable for such high-precision dosing units Beamflex PCMR10-A. This aluminum helical coupling has an outer diameter of 9,5 mm. The coupling has friction-locking clamping hubs. These are balanced for smooth running even at high speeds.

Miniature stepper motor positioned in the tightest of spaces

The backlash-free All-metal coupling offers a torque transmission with a torque of 0,62 Nm. Shafts with a diameter of 3 mm can be connected through the couplings. These are made of aluminum or, if used in aggressive media, optionally in stainless steel. In addition to the clamping hub variant, the shaft can also be attached using threaded pins.

The compensating coupling Beamflex PSMR7 is even smaller. The micro shaft coupling made of aluminum has an outer diameter of only 6,5 mm. They are available for shaft diameters from 1 to 2 mm. The coupling is suitable for delicate, precisely operating equipment such as processing systems for precision mechanics and optics, laboratory systems or the smallest industrial diagnostic devices and inspection systems.

Pluggable, modular cross slide coupling

The micro compensating couplings in the Oldham Portfolio. Such an electrically insulating coupling consists of two aluminum hubs with adjusting screws and an acetal transmission disc. The three-part structure ensures any combination of the most varied of bore diameters from 1 to 4 mm.

The Oldham coupling is available in the three sizes ZOS6, ZOS8 and ZOS10 with outside diameters of 5,9, 7,9 and 9,9 mm. Due to their compact design, these micro-couplings are also suitable for small installation spaces.

Oldham couplings made of stainless steel for servo drives

09.05.2019 | Ruland now offers Oldham couplings with hubs made of stainless steel 1.4305. Designers can now choose from an additional standard option when designing equipment for corrosive, vacuum or cleanroom environments. The stainless steel couplings are free of play, can compensate for any misalignment and are structurally balanced.

Oldham clutches consist of two hubs and a centrally mounted disc for torque transmission. Through the three-part structure The couplings allow users to easily combine coupling hubs with bores in metric or imperial dimensions, with or without a keyway, and in a clamping or adjusting screw version.

Oldham couplings are structurally balanced for vibration-reduced use and can operate at high speeds of up to 6000 min^-1 be used. Their bearing stress is low and they protect sensitive components such as bearings from premature failure. Thanks to the company's proprietary hub machining process, the drive elements offer longer service life and less downtime.

The Center disc The Oldham coupling is available in different versions: made of acetal for freedom from backlash and the transmission of larger torques, made of polyetheretherketone (Peek) for applications with high temperatures and outgassing restrictions, and made of nylon to reduce noise and absorb shock-like loads. Oldham clutches also act as a mechanical safety device in the event of a torque overload, as the center disk breaks cleanly and stops power transmission in the system.

By the use of stainless 1.4305 Combined with a Peek center disc, designers can now use a standard Oldham coupling for a wider range of servo drive applications, for example in the food and packaging industries or medical and scientific devices.

Compensating coupling for linear drives with 0,1 mm play

29.01.2014/XNUMX/XNUMX | The ones offered as standard for linear drives coupling elements for connection to the customer's own guidance have mechanical play due to the design.

That's why they are accurate positioning tasks - regardless of whether with electric or pneumatic drives - can often only be achieved with in-house developed coupling solutions. The “Dard” driver from Festo has a mechanical play of less than 0,1 mm.

It ensures the compensation of Misalignments up to 2,5 mm between the guidance of the load to be moved and the linear drive. The driver is available from stock for drives in sizes 18 to 80 mm.

It can be installed even if the drive and guide are already installed. This is particularly advantageous when servicing the products.

There are three series with a maximum permitted Radial misalignment Depending on the coupling size and version, up to 275 mm. Versions with adapted surface coatings enable adaptation to a variety of machines under special environmental conditions.

In packaging machines for pharmaceutical products, there are special regulations regarding the required materials for machine parts and drive components to be used.One was created for this requirement Stainless steel version developed. The connecting disks and the middle disk are made of stainless steel 1.4541.
