Principle of Strain Wave Gears Principle of Strain Wave Gear Composition of Strain Wave Gear Characteristics of Strain Wave Gear Strain Wave Gear consist of three basic components: Wave generator, flexspline and circular spline. High Accuracy: A significant portion of the teeth are always engaged in two zones 180 degrees apart. This neutralizes the effects of tooth pitch errors and accumulated pitch errors, ensuring high positional and rotational accuracy. Wave generator: it is made up of a wave bearing and an elliptical cam. The Wave generator is usually attached to the input end. The inner...

Technical Information • Torque capacity increase 15%-30% • Temperature rise decreased by 8-10°C • Minimize the tooth surface contact area prone to fatigue pitting • Service life exceeds 15,000 hours Technical Information About FS tooth profile We have made several upgrades to the traditional theoretical double-arc profile. The original two-curve continuous arc profile has been optimized into a multi-segment continuous arc with varying curvatures. This ensures proper gear meshing in the reducer while reducing relative sliding friction, thereby mitigating the risk of grease failure caused by grease...

Technical Information TERMS AND DEFINITIONS ■ Starting Torque It is the minimum torque value applied to the input end at which the strain wave gear first starts to rotate with no load. ■ Maximum Average Input Speed It is the average value of input speed. ■ Permissible Peak Torque for Start and Stop It is the maximum torque as a result of the moment of inertia of the output load during acceleration and deceleration. ■ Permissible Maximum Momentary Torque It is the momentary peak torque the strain wave gear may be subjected to the event of a collision or emergency stop. It indicates allowable continuous...

Technical Information Angle transmission accuracy indicates the difference between the logical rotating angle and the actual rotating angle as the angle transmission error when any rotating angle is given as an input. Torsional angel Angle Transmission Accuracy Hysteresis loss Lost motion Stiffness Diagraph From the stiffness graph, parameters such as backlash, stiffness, hysteresis loss, and lost motion can be obtained. → Fix the circular spline and input end (Wave generator) of the strain wave gear, and when ±2% rated torque is applied to the output end (flexspline), a small amount of angular...

Technical Information SELECTION PROCESS Flowchart of Model number selection In general, the servo system is rarely in a continuous constant loadstate. The input rotational speed, load torque change and comparatively large torque are applied at start and stop.Unexpected impact torque may be applied. Select a Model number according to the following flowchart. If you find a value exceeding that from the ratings, you should review it with the upper-level Model number or consider reduction of conditions including the load torque. These fluctuating load torques should be converted to the average load...

Technical Information ON THE Wave generator Basic structure and shape of Wave generator shown as below. The Wave generator includes a structure of a European-style coupling with a self-aligning structure and an rigid type without an automatic self-aligning structure and varies depending on the series. For details, please refer to the outline drawing of each series. Oldham coupling Structure Utiling a European Style Coupling ① Retainer ② Wave bearing ③ Wave generator Plug ④ Insert hole ⑤ Rubwasher ⑦ Wave generator hub Oldham coupling Rigid type Axial force direction of the Wave generator Axial...

Technical Information PRECAUTIONS ON ASSEMBLY The connecting and fixing method of Wave generator Wave generator Key Flat Gasket Technical Information 1. Input shaft has a shaft shoulder, it can be connected with Wave generator directly. As shown in the figure. 2. Input shaft has a shaft shoulder, but it‘s too long. You can add a space ring on the shaft(the parallelism of the spacer ring should be within 0.01mm), then connect and fix it through the thimble screw on the Wave generator. As shown in the figure. Input Shaft Flat Gasket Wave generator Space Ring Input Shaft Wave generator Connection...
