Fine Cyclo®

Product catalog summary

Construction
The FINE CYCLO® speed reducer features a unique design that integrates a planet gear with cycloidal-shaped teeth and a fixed internal sun gear with circular pin teeth, distinguishing it from traditional involute gearing mechanisms.

Application Examples
The document showcases various configurations of the FINE CYCLO®, illustrating its adaptability in different mechanical setups, such as reducers and increasers, based on input and output shaft arrangements.

Nomenclature
A detailed breakdown of the model naming conventions is provided, covering frame size, reduction ratio, and special specifications.

Products
A comprehensive list of available models is categorized by frame size and reduction ratio, indicating the range of products offered.

Speed Ratio & Rotation Direction
The document explains speed ratio calculations and rotation direction for different configurations, using symbols to denote relationships between input and output speeds.

Operating Principles
The operating principles focus on the internal planetary gearing mechanism and constant speed internal gearing mechanism, including equations for calculating velocity ratios based on the number of teeth in the planet and sun gears.

Rating
Tables provide detailed ratings for input speed, reduction ratio, rated output torque, and allowable input power across different frame sizes, including maximum acceleration or deceleration torque and peak torque for emergency stops.

Engineering Data
Data on stiffness, lost motion, no-load running torque, and efficiency are included. Efficiency curves show how efficiency varies with input speed and load torque for different frame sizes.

Main Bearings
Details on main bearings include moment stiffness and allowable moment and axial load, with formulas for calculating external moments and loads.

Selection
Guidelines for selecting the appropriate model based on application requirements, including considerations for radial and axial loads, are provided.

Notice for Designing
Recommendations for designing systems using the FINE CYCLO® include considerations for lubrication, temperature, and assembly accuracy.

Outline Drawing
A visual representation of the FINE CYCLO® components and their arrangement is provided.

Specifications and Formulas
Formulas for calculating equivalent axial load (Pae) and moment stiffness are provided, using factors such as coupling factor (Cf) and shock factor (FS1). Tables C-13 and C-14 list values for these factors based on different load conditions and connection types.

Tables and Data
Critical data for calculations are provided in several tables, including:

Table C-10: Span of Loading Points for different frame sizes.
Table C-11: Moment Stiffness values for various frame sizes.
Table C-12: Allowable Moment and Axial Load for different frame sizes.
Table C-16: Tightening torque and allowable transmitted torque by bolts for various components.

Selection Process
A flowchart outlines the selection process for the appropriate frame size and evaluation of load characteristics, including steps for calculating average input speed, output torque, and checking radial and axial loads against allowable limits.

Example Calculation
An example calculation for a specific reducer (F2C-C25-119) used in a robotic application is provided, detailing the calculation of %ED, input speeds, and torque evaluations.

Assembly and Design Considerations
Guidelines for assembly precision, tightening torque, and lubrication are provided, emphasizing the use of specific bolts and adhesives to prevent loosening and ensure proper assembly.

Warranty Information
The warranty section outlines conditions and exclusions for product warranty, specifying a period of 18 months from delivery or 12 months from operation, and detailing scenarios where the warranty does not apply, such as improper installation or natural disasters.
