Brand new couplings
by Mayr Antriebstecnik, KTR, Orbit Antriebstechnik, Schmidt-clutch
Rden now offers shaft joints from Belden via its eCommerce platform. The wide range of plain bearings and needle bearing joints for machine construction is available in alloy steel and stainless steel, in a standard version from stock or with machined hubs at the customer's request. The shaft joints expand the range of drive elements from Ruland. They complement the product portfolio of backlash-free precision couplings. These include rigid coupling, flexible beam coupling, bellows coupling, Controlflex coupling, multi-plate coupling, elastomer coupling and Oldham coupling.
KBK Antriebstechnik has developed the KBGK and KBGK-T articulated couplings that connect shafts and components with extremely little play and even compensate for high radial and angular misalignments. They are made from high-quality materials such as aluminum and steel, are torsionally rigid in the circumferential direction and give in to radial forces and angular deviations.
The connection of a ball screw drive or a trapezoidal screw to the drive journal of a motor or gearbox is usually not done rigidly, but via a flexible coupling. This can be used to compensate for center offsets or misalignments and to minimize vibrations and shocks in the drive train. Dr. Tretter now offers compact shaft couplings for this.
SPS Hall 3, Booth 419 Rigid couplings of the "Torqmax step bore" series from Orbit Antriebstechnik enable the play-free connection of shafts with different diameters thanks to their graduated bores. For a low mass moment of inertia, the couplings are made of aluminum, additionally anodized to prevent corrosion, and some are also available in stainless steel.
EMO Hall 5, Stand D89 The "Simple-Flex" series from Jakob Antriebstechnik is a new type of spacer coupling that can be manufactured up to a length of 6 m and does not require additional intermediate storage. A sophisticated composite tube with a multi-layer, angle-specific fiber configuration enables a particularly simple design that does not require any coupling compensation elements at the tube ends.
EMO Hall 3, Stand E22 Ringspann presents the new clamping coupling for fixing driven rotary swivel tables in multi-axis machining centers. Immediately after its first presentation last autumn, this mechanical-hydraulic high-precision solution has become the favorite of numerous well-known manufacturers of machine tools and swivel-swivel portals.
Flender completes its "N-Arpex" coupling, which was introduced in 2017, and introduces two further expansion stages with eight and ten screw points. As a result, the coupling series covers a diameter of up to 988 mm and a torque of up to 2.000.000 Nm. Due to the compact design and an increased bore capacity, a size increase is also possible.
Jakob Antriebstechnik offers the metal bellows coupling "KPP" in order to meet the ever increasing requirements with higher outputs. Their nominal torque is over 600 Nm and the maximum torque is around 1200 Nm. It has to withstand operating speeds of up to 10.000 min-1 and therefore extremely high dynamic loads.
Ruland now offers Oldham couplings with stainless steel 1.4305 hubs. Designers can now choose from an additional, standard option when designing systems for corrosive, vacuum or clean room environments. The stainless steel couplings are free of play, can compensate for any form of offset and are structurally balanced.
