Reciprocating conveyor with reinforced floor members

摘要

The ball end (16) of the piston rod (14) of a linear motor (6) is mounted in a ball block (52). The block (52) has mating housing portions (54, 56) that abut along mating surfaces (64) that are substantially parallel to, but slope relative to, the motor axis (X). One housing portion includes an integral rear wall (70) through which the axis (X) extends and which defines a portion of a socket (58) that receives the ball end (16). The other housing portion has a flange (78) that projects into a space between the socket (58) and a sloping extension (74) of the wall (70). The outer surface (76) of the wall (70) is secured to a fixed support (84). The wall (70) transmits loads carried by operation of the motor (6) from the ball end (16) directly to the support (84) and minimizes loads on the fasteners (68) securing the housing portions (54, 56) together. The housing portion that includes the wall (70) is made from a material with a high load carrying capability. The other portion is relatively easy to machine and includes a passageway to deliver fluid to the ball end (16). A reinforcing bar (150) extends rearwardly from the motor (6) through a channel formed by a floor member of a reciprocating floor conveyor.
