Description of πŸ“š The Ultimate Guide to Boston Gear NB24B Pressure Angle: Features, Benefits, and Applications

Transmits torque between parallel shafts to provide rotational power to another part of a motorized system. Pressure angle of 14.5 degrees for a higher contact ratio between gears, resulting in quieter operation than larger pressure angles. Diametral pitch of 16 for applications requiring a balance between transferring torque and controlling changes in speed and direction of rotation with precision. Low carbon steel (.2 percent carbon) for applications where the hardness and strength of higher levels of carbon are not needed to transmit torque and motion.

Not as advertised

Do not trust the pictures or the description. No key slot. No adjusting screw. I had to manually drill and cut holes in my own screens. This is for press use only.

Pros
  • Transfers torque between parallel shafts to deliver torque to another part of motorized system
Cons
  • Obsolete

Good gear but different from photos

Product deserves a 5 star rating but the zero star description downgraded it to 3 stars. The pictures show both the keyway and the set screw. This article has neither. If you just need a set screw, try http://www.amazon.com/gp/product/B004BDO36O/ref=oh_details_o03_s05_i00?ie=UTF8&psc=1. Time to bring her back and we must do our own work to make it happen.

Pros
  • 14.5 degree contact angle for higher gear contact ratio resulting in quieter operation than at larger contact angles
Cons
  • Not sure

No adjusting screw? No problem

Quality product at a reasonable price and very fast delivery. Doesn't have a keyway or set screw BUT you shouldn't have either. If you know how to drill a hole, then you're in luck. Just drill a hole where you need the set screw and also through the shaft you are mounting it on. Then install the roll pin through the gear and shaft. This requires more torque than the screw and will hold the gear in place. You don't have to weld it.

Pros
  • Diameter pitch 16 for applications requiring a balance between torque transmission and precise control of speed and direction changes
Cons
  • Large and bulky
