DATORKER® strain wave gears General information 2. General information 2.1 Characteristics DATORKER® strain wave gears DATORKER® strain wave gears has the characteristics of high precision, high efficiency, high torsional rigidity and low starting torque. It is widely used in robots, automation equipment, semiconductor equipment, machine tools and other industries. HIWIN has developed a variety of different models with different gear ratios in order to be able to offer a wide selection. Features DATORKER® strain wave gears { Compact and light weight – easy for user to assemble and work with...

2.1.2 Positioning accuracy The positioning accuracy depends on several factors. On the one hand, the accuracy of the angular transmission plays a role; this indicates the basic accuracy of the gear unit. In addition, there is angular displacement due to the torsional rigidity; this depends on the applied torque and the resulting angular displacement is subject to a hysteresis loss. 2.1.2.1 Accuracy of angular transmission With an input angle of rotation (0i), a theoretical output angle of rotation (02) results based on the reduction ratio. The difference between the theoretical output...

DATORKER® strain wave gears General information 2.1.2.3 Hysteresis loss After the torque is applied at the nominal value and reset to “0”, the torsion angle is not completely “0” and has some displacement (B-B’), which is called hysteresis loss. The hysteresis loss is mainly caused by internal friction. When the torque is extremely small, it is almost non-existent. Ө Torsional angle 2.1.3 Low starting torque The starting torque defines the torque required without load to set the gear unit in motion. Because the shaft generator is supported by balls, only the rolling friction has to be...

Calculation of the average input speed F 3.3 Calculation of the maximum input speed F 3.4 3.3.5 Nominal service life of the gear unit The service life of the gear unit depends on the flexible bearing of the shaft generator. The nominal service life of the shaft generator is 35,000 hours. The calculation formula is as follows: F 3.5 Tr = Nominal torque nr = Nominal speed 3.4 Selection of DATORKER® shaft gear unit design and specification Select the DATORKER® shaft gear unit design according to the operating requirements and check the nominal power table of each unit according to the...
