Subsystem Design

Background Information

Quick Project Overview

Gleason currently uses a test fixture in which the load is manually applied to the arbor in one static direction. In the subsystem design phase we went with our “Pivel Swivot” fixture, which was approved from the system design review, and split up all the subsystems to different individuals on the team. We were able to draw the fixture in Solidworks and apply simulations in order to see if our design can withstand the desired force. The owner of each subsystem found any parts or devices that needs to be bought from an outside source and listed them out with their respected price. The subsystems were necessary in order to come up with a successful design that can apply a multiaxial force from outside the machine instead of the design Gleason currently uses.

Discussion with Mike indicated that a system for supplying the hydraulic pressure, similar to the one pictured below, could likely be provided by Gleason.

Overload protection will be provided by an adjustable relief valve, set to a desired pressure given the application.

Load Cell

Requirements

Final Selection

At one-half inch in thickness, Selected load-cell is the smallest available for the price. Since this load cell does not have threading, a holder will be designed and machined for it.
