Transfer Shuttles Applications
Trantek Drive Systems
Inc., offers Screw Driven Robot and Tooling Shuttles.
TranTek Drive Systems Inc. has been providing screw driven
shuttles to move robots and tooling in automotive feeder plants. A typical
shuttle must move 5,000 pounds at a maximum speed of 8 feet/second along
varying length indexes (as short as 5 feet and as long as 150 feet). The
tooling shuttles typically move 2000 pounds.
TranTek Drive Systems, Inc. has provided these screw driven
shuttles when the application and environment are not well suited for other
types of shuttles (eg. Rack and pinion driven). The screw driven typical
shuttle includes:
- Heavy duty steel
frame weldment
- Hardened and ground
wear rails
- 2 _ diameter high
lead (six inches) cold formed screw
- Heavy duty patented Dri-Tran®
polymer nut
- Follower and drive
end bearings
- Gear reducer
- Cat track assembly
- Steel carriage with
gear reducer mounting assembly
- Screw cover/guard
- Heavy duty load
runner bearings
- Machined interface
tie plate for joining 16 foot sections for longer shuttles
- Mastering
pin/fixture assembly for mastering robot position
- Electronic/automatic
lubrication device for Dri-Tran® polymer nut
- Rail wipers to
remove debris
- Rail covers to keep
debris off the rails
- Leveling and floor
mounting assembly
- Safety stops
TranTek provides system integration and a 20 hour run-off
by integrating the robot and robot seventh axis drive package and cycling
the robot/shuttle along the length of the shuttle.
