Abstract
A inverted spline rail system is provided. The inverted spline rail system includes a drive motor that rotates a drive screw. The drive screw has a associated nut body. The nut body includes a attachment portion that a user can attach a device that requires linear motion control. Furthermore, the nut body is located inside of a cylindrical body that encases the drive screw. The nut body has guide teeth that mate with an internally splined guide rail of the cylindrical body that contains both the nut and the drive screw. The reciprocating nature of the guide teeth of the nut and the internally splined guide rail of the cylindrical body translate the rotational motion of the drive screw into linear motion of the nut body. The inverted spline rail system is protected from its operating environment by a seal.
