Premium Stephan Hameln The foundations were laid over 100 years ago: In the small mill belonging to the Stephan family in the 1890 s, everything already centered around the perfect drive system. And this is how it has remained though we have of course grown in the meantime. Since 2011 Premium Stephan is part of the International Premium Transmission Ltd. Group. In Hamelin / Germany, we develop and produce premium precision gearboxes for the robotic and automation industry as well as geared motors, industrial gearboxes and customised gearboxes. This enables us to offer customers tailored solutions, from a standard gear unit, through products adapted for specific applications, to custom-made gear units. The MELIOR MOTION range is another exciting innovation from Premium Stephan. With its unique zero backlash system, it raises the bar in drive technology.

MELIOR MOTION zero backlash precision gearboxes With 30 years experience in the development and production of highly precise precision gearboxes for industrial robots, the new compact gear range MELIOR MOION has been presented to the market. The unique advantages convince in robotics applications, as well as in medical industry, machine tools and other automation industries. Picture 1: MELIOR MOTION sub-assembly, hollow shaft With a backlash of 0.1 arcmin, the MELIOR MOTION range can be considered as zero backlash gearbox. They are available in seven sizes, each as sub-assembly or fully enclosed gearbox unit and as solid or hollow shaft version. Sub-assemblies can be directly integrated into your drive system or machine design. As an alternative, we offer fully enclosed gearboxes which are filled with a standard mineral oil. Geared motors can be supplied on request. Picture 2: MELIOR MOTION fully enclosed gearbox, solid shaft with motor flange and coupling for easy motor adaption Hollow shafts up to 75 mm dia. allow a feed-through of cables or similar.

Torsional stiffness Torsional stiffness is defined as the quotient of applied output torque and generated torsion angle and is given in Nm/arcmin. The input shaft of the gearbox is being blocked, the output is loaded and unloaded with continuously increasing torque. The torsion angle on the output records the torque and results in the hysteresis curve which provides the torsional stiffness. 8 7 6 5 Figure: hysteresis curve on example PSC160-V Torsional stiffness (practical test) Backlash, Lost Motion Winkelminuten [arcmin] 4 3 2 1 0-1 -2-3 -4-5 -6-7 -8-2500 -2250-2000 -1750-1500 -1250-1000 -750-500 -250 0 250 500 750 1000 1250 1500 1750 2000 2250 2500 Drehmoment [Nm] The torsional backlash is the angle tolerance of torsion of the output shaft in relation to the input shaft at zero torque. The measurement is done when input shaft is blocked. The torsional backlash can also be seen in the hysteresis curve. Lost Motion, also called positioning error, means the torsional angle on the output which is reached if all outer loads are removed. The measurement is taking place at +/-3% of nominal torque. 2 1,75 1,5 1,25 22 Figure: hysteresis curve on example PSC160-V Backlash, Lost Motion (practical test) Winkelminuten [arcmin] 1 0,75 0,5 0,25 0-0,25-0,5-0,75-1 -1,25-1,5-1,75-2 -200,0-150,0-100,0-50,0 0,0 50,0 100,0 150,0 200,0 Drehmoment [Nm]

Precision gearbox PSH-D The precision gearbox PSH-D originally was designed for the use in Delta Robots. However, it may also be used in any other application where highest precision in combination with fast reverse movements is required. On Delta Robots varying product weights and differing pick & place distances play an important role when designing a gearbox. The challenges involve very high cycle numbers and short, highly dynamic motions in a high duty cycle. With the development of a high precision gearbox which may be used in robotics and automation industry, highly dynamic drive systems with constant precision can be offered. The gearbox has a hollow shaft to allow a feed-through of cables. A variable motor interface allows individual motor adaption. The precision gearbox PSH-D is a helical gearbox with a special tooth profile which guarantees a very low backlash which remains on a constantly low level throughout the whole lifetime of the gearbox. The housings are made of high-grade aluminium alloy which makes a contribution to the low weight. Only bearings from well-known bearing manufacturers are used to secure the highest possible quality. The gearboxes can be assembled in any mounting position and are also available in solid shaft version. Pictures: Precision gearbox PSH-D 26
