摘要

A modular construction linear drive has a single track (2) with an integral ratchet track (3) and fitted with a drive block (4) via a shaped slot and with bearings to grip either side of the track. The drive block is fitted with two drive housings (10, 11) containing a pinion which meshes with the track via an aperture in the top of the drive block, and with the drive via an external servo motor. The two housings over lap the drive block and are separately secured by threaded fasteners.
