We are committed on supporting the R&D efforts OEM gear , ODM gear , gear manufacturingof our customers thereby reducing the development costs.
Sizing of tool designs
- Define grinding stock for hard finishing
- Size protuberance and tip chamfer
Based on the required grinding stock, the appropriate protuberance at the tool can be calculated. When a protuberance is applied, an increased root fillet radius can be achieved.
Tools with a modified pressure angle
- Calculate the tool module and pressure angle
- Analyze the root rounding and root form circle
Tools with a modified pressure angle and module are widely used for soft and hard machining.
This results in an improved tool life and optimized root form circle to achieve highest contact ratio.
Grinding tools
- Determine the minimum necessary grinding depth
- Profile and threaded wheel grinding
At the click of a button, the grinding tool addendum can be calculated for different grinding process requirements such as the minimum required active root diameter, maximum root form diameter, grinding of root land, etc.
Profile & lead modifications
- Profile, lead and combined modifications
- Display K-diagrams
In KISSsoft, various modification types in profile and lead direction can be defined, such as tip and root relief with different transition types, end relief, twist, etc., and even topological modifications.
The gear modifications for left- or right-hand flanks can be defined independently of each other, to ensure an optimum drive or coast side meshing performance.
Root rounding & tooth root stress
- Grinding notch analysis
- Stress concentration in the tooth root
To identify stress concentration, an FEM calculation is used to analyze the tooth root stress present for root rounding or grinding notches.
A 2D FEM calculation is sufficient to determine the tooth root stress caused by grinding notches. A 3D FEM calculation is recommended if the influence of a flank modification is to be taken into account.
Natural twist
- Simulation of twist created by threaded wheel grinding
- Use of LTCA to analyze noise excitation
Natural twist occurs during threaded wheel grinding of helical cylindrical gears with crowning. This twist is simulated in KISSsoft and rated with the loaded tooth contact analysis (LTCA).
The loaded tooth contact analysis shows the behavior under load, such as stress distribution and contact pattern. The transmission error (PPTE) is used to analyze the noise excitation of gears.
