Re: AndyMark transmissions at IRI

There is a Super Shifter page on the AndyMark website. More details (CAD, assembly drawings) will be released within 5-6 weeks. Here are the key features and improvements:

An additional shaft, with 2 standard ratios (2.25:1 or 2.82:1) that would reduce the speed in addition to the current output speeds of the AM Shifter

An included encoder, US Digital model E4P-250-250, located on the final drive shaft

Common shift hardware used both for pneumatic or servo shifting, so choosing between one or the other is easier

An enclosed gearbox, much like our http://www.andymark.biz/am-0011.html, but wider (and a bunch more stuff included)

A 1/2" output shaft, with a 1/8" keyway and a 1/4-20 threaded hole on the end

Ability to mount 2 CIM motors (not enough room for a Large CIM motor)

1/4" thick aluminum side plates

The same gearing (mostly) as the AM Shifter in the cluster gear shaft and output gears

We have not set a price yet, but we are looking at $370 as a target. Keep in mind that 2 gears, 1 shaft, and 1 encoder are all being added. Also, we are debating about providing both the pneumatic and servo shift options for each gearbox. It is super.
