gear system

• 9.6 est small diameter ?? . (15 teeth?), 5mm more
• ~25mm diameter - (40 teeth), 6mm bore
• w/belt 26.32mm diameter
• 35 mm spacing
• current ratio ~2.5
• large pulley radius could grow by 7.3mm (abs max) - although part of the pyramid is in the way. lathe to fix that.
• 39mm pulley has 62 teeth - for a ratio of 4.13!

motor / assembly

• left ankle belt riped, and replaced at 5.64N. Pully had runout, caused by under dimension of the pully. Believed to be cause of belt break. Everything fixed.

drive 1

• 01-16-09 : DRIVE 1 GEAR BOX IS OUT OF SEVICE! THE EC30 MOTOR from this drive is now in drive 3
• 1-11-09 : tried to replace with new GT2 white belt - but 2nd motor bearing cover has damaged torx screw
• 1-11-09 : the belt was probably replaced (with better used belt) on 12-8-09
• 12-8-08 : belt tension missing 1 of the 4 screws (head is broken)
• 11-28-08 : verified with +-1.5Amps

todo

• remove torx screw - possibly drill out and replaced with a hex flat head?

drive 3

• right ankle belt previously tensioned at 5.64. Today was measured to be 4.2 - 4.4N. Retightened to 5.6
• 01-16-09 : DRIVE 3 IS NOW MATED WITH EC30 MOTOR FROM DRIVE 1 and is installed in Proto 1 with new White GT2 Belt and adjust to 5.64N using outlined fixture process

drive 4

• 01-22-09 : Replaced motor and re-adjusted belt to new set point of 6.64N
• 1-21-09 : installed into 'backup'
• 1-21-09 : Bearings have been replaced
• 1-19-09 : has defective thrust bearing
• 1-12-09 :Installed New White GT2 Belt and adjust to 5.64N using outlined fixture process

drive 5

• 12-6-08 : CEB tests drive, no response on any channel - all high - probably ground is open
• 12-5-08 : robert repairs encoder - by replacing with encoder from frozen motor
• 12-4-08 : problems with encoder, no pulses on channel b
• 11-28-08 : verified with +-1.5Amps

drive 6

• 1-19-09 : belt replaced with white GT2 and tensioned
• 12-6-08 : motor 6 pully has a problem. mounted incorrectly?
• 12-6-08 : added motor connectors
