Apparatus and process for using a self-aligning bearing |
摘要 |
An apparatus and process for using a self-aligning bearing having a ball movably seated in a socket mounted in a wall of an explosion-proof enclosure and slidably receiving a shaft for transferring motion from the outside to the electrical equipment inside of the enclosure. The abutting surfaces between the ball and socket of the bearing and the ball and the shaft have minimum flame path lengths to meet minimum safety requirements for extinguishing electrical arcing passing along such abutting surfaces.
