Closed-loop belt differential actuator - 1 year ago
Let me start a discussion about pros and cons of the interesting linear belt drive kinematics. Assumptions: Static plate with two motors with timing pulleys ( A, B ) and two idlers; Moving plate with two idlers; Closed-loop belt; Moving plate is constrained in single axis. This system has several modes of operation based on the difference of rotational speeds of motors. 1. If A and B have tby grytole - Mechanics
Re: CoreXY 2:1 belt ratio double torque and resolution ? - 4 years ago
QuotePippy Would adding the four middle pulleys double the torque and resolution ? I'll vote for "not really". It seems like a reduction only for horizontal axis - when both motors spinning at same direction. When motors are spinning as cw/ccw - I can't see any reduction in vertical axis, because a whole block system is unused. It is just a brief look, I can be wrong)by grytole - CoreXY Machines
