Building a chain pulley

Hey, trying to build a moving airgun target super simple pulley system using an attachment chain. I have no background with robotics, engineering or mechanics and with all the options on this website i am completely lost. I have the targets built but i need to build the pulley system. What I know that I need:

  • a low rpm motor motor, preferably one that i can change the speed
  • a drive sprocket to attach to the motor
  • a way of attaching the drive sprocket to the motor
  • a second sprocket
  • a chain with a way to attach targets (see picture at bottom)
  • a mounting bracket to mount the motor and spockets to the top of my target box

can anyone provide links or item numbers. I have no idea which ones I need.

basic idea:

Hi Allheart,

In order to find a good motor for your project, you need to know the RPM and Torque required. Start by looking at those two blog posts:
RobotShop Blog - Drive Motor Sizing Tutorial

We have a Gears, Belts, Pulleys, Tracks, Sprockets & Chains category if you want to start looking at what’s available.
