A linear motion device having an elongated body a carriage moveable in a linear path relative to the body and a bearing positioned between the carriage and body for supporting the carriage for movement along the linear path. The device further includes a wedge member in the body for adjusting the position of the bearing.

Linear motor device

The present invention provides a rotary gripper for robotic use including a support portion for connection to a robotic apparatus, a gripper head movably mounted on the support portion and carrying a pair of opposed gripping fingers, a first drive mechanism for opening and dosing the gripper fingers and a second drive mechanism for rotating the gripper head. The drive mechanisms are generally transverse relative to each other and each includes at least one pneumatically driven, reciprocating piston. In the first drive mechanism, a pinion gear is operably connected to the piston for reciprocating movement therewith. The piston in the second drive mechanism is operably coupled to a rack engaging the pinion gear to turn the gear, thereby moving the gripper head relative to the support portion.

Multimotion actuator for a rotary gripper

A linear motion device having an elongated body a carriage moveable in a linear path relative to the body and a bearing positioned between the carriage and body for supporting the carriage for movement along the linear path. The bearing includes a side rail adjustably connected to the body and bearing elements between the carriage and the side rail.

Linear motion device

A tumbler drive mechanism having a rotatable tumbler body mounted on a shaft and a plurality of tumbler lugs removably mounted on the tumbler body. The shaft has a longitudinal axis about which it and the tumbler rotate. The tumbler body includes a center drum and a plurality of circumferentially spaced apart radially projecting drive flanges. Each one of the plurality of tumbler lugs is mounted between and in engagement with two adjacent ones of the plurality of drive flanges. Each of the tumbler lugs engages the shoe lugs of a crawler track as the tumbler body rotates to drive the crawler track. The tumbler lug is mounted on the tumbler body at a selectively variable radial distance from the axis of the tumbler body. The radial distance at which the tumbler lugs are mounted on the tumbler body is accomplished by providing one or more shims positioned between the lug and the tumbler body.
