Selection Method for KHK Standard Gears

Please select the type of gear that matches the actual load torque applied to the gear and the intended purpose.

The method for selecting gears varies depending on which factors are prioritized in the design, such as strength, size, precision, and reduction ratio. Here, we will introduce "selection based on strength" and "selection based on intended use" as guidelines. 【Selection Based on Strength】 ○ Determine the actual load torque on the gear and the appropriate type of gear for the intended purpose. ○ Make a preliminary selection based on the load torque from the allowable torque tables in the comprehensive catalog or web catalog. ○ Conduct strength calculations under actual usage conditions to evaluate the appropriateness of gear strength. 【Selection Based on Intended Use】 ○ High-speed rotation ○ High strength (compact) ○ Backlash ○ Indexing and positioning ○ Cost performance ○ Machinability ○ Large reduction ratio ○ Rust prevention measures
