I don`t know if you can find such a gear in the rc car segment, but I would suggest you to contact a fine pitch gear manufacturer. Though its unlikely to get a single piece machined, but still its worth the try because these specialized manufacturers are gonna solve your requirement in a correct way. Of-course price might be an issue :( but you need to work it out. http://www.bevelgearsindia.com/html/products.html Title: Re: 1.15mm pitch Pinion needed..

Do remember, the pinion hardness should be less than the gear hardness, if not then the pinion is going to wear out the gear and changing a gear would be expensive than changing a pinion. If rpm is high and power transfer is also high (roughly estimating over 200 watt for your pinion), then do give my suggestion a second though. Even if the involute profile of the gear teeth are not cut properly then there is trouble to be seen. Gear design is a critical and complex field. |
