Linear bearing compensation system

摘要

An alignment compensation system for use with parallel linear bearings which isolates the linear motion system load or carriage plate from alignment errors in the system. Spherical bearings are mounted in bearing blocks, each spherical bearing having a support shaft therethrough to support a plate connected to a carriage or load plate. One of the bearings shafts is free to laterally float within its bearing block, thus providing for compensation of lateral misalignment of the linear bearing track. The other spherical bearing is held fixed within its bearing block. The linear system load or carriage plate is mounted on the spherical bearing shafts, thus isolating the carriage plate from alignment errors in the linear motion system.
