There are a number of questions you need to ask yourself when designing a plastic gear. We can help you with these questions....
Examples:
How much backlash does a plastic gear require?
How much allowance in backlash is to be allocated to moisture absorption?
What is the impact of a cast-in metal core on the backlash?
Am I taking a risk by just replacing a metal with a plastic gear?
Is a bigger or smaller tooth better for my application?
How fast can the gears turn without lubrication?
Can the class of the gear change in different environments?
Can I reduce inertia and maintain adequate gear strength?
How do you increase tooth rooth strength up to 18% when face width is limited?
How do you determine flank pressure safety?
How many hours will a gear run in a given application?
What is the most suitable material for my application?
How do I attach the gear to the shaft?
What are the alternatives for large and small gears?
Can a plastic gear be used in sub-zero, such as -50 degree F, temperatures?
What is the difference in gear life between pressing an all-plastic gear onto a shaft vs. pressing on a gear with a metal core?
What is the largest OD I can design with plastic?
Can a bearing be safely installed in small plastic idler gears?
Why are some plastic gears noisier than others?
Should the pinion or the driven gear be designed from plastic?
Which plastic material has the highest impact strength for my shock load application?
