Patent number: 9379591Abstract: Couplings between driven shafts of an actuator and a motor of an actuator are provided. The coupling may be directly integrated into a rotor of the motor. The coupling may be provided by an adaptor that includes a shaft that extends into a central bore of the rotor of the motor. The adaptor can include a collar that defines a coupling recess that receives a distal end of the driven shaft of the actuator. The collar may take the form of a clamp.Type: GrantFiled: July 19, 2013Date of Patent: June 28, 2016Assignee: Pacific Bearing CompanyInventors: Robert Schroeder, Jonathan R. Schroeder, Joseph A.

Patent number: 9334937Abstract: A linear guide including a guide rail, a carriage, a drive screw and a connection arrangement is provided. The guide rail defines a linear travel path. The carriage is mounted to the guide rail for motion along the linear travel path. The drive screw is operably mounted to the guide rail. The connection arrangement couples the drive screw to the carriage to convert rotary motion of the drive screw to linear actuation of the carriage along the linear travel path. The connection arrangement provides a single degree of linear freedom between the drive screw and the carriage in a direction that is generally perpendicular to the linear travel path. The single degree of linear freedom permits relative motion between the screw and the carriage to relieve internal binding between the relative components.Type: GrantFiled: July 3, 2013Date of Patent: May 10, 2016Assignee: Pacific Bearing CompanyInventors: Robert Schroeder, Jonathan R. Schroeder, Joseph A. Binka, Paul D. Ross

Patent number: 9303742Abstract: A inverted spline rail system is provided. The inverted spline rail system includes a drive motor that rotates a drive screw. The drive screw has a associated nut body. The nut body includes a attachment portion that a user can attach a device that requires linear motion control. Furthermore, the nut body is located inside of a cylindrical body that encases the drive screw. The nut body has guide teeth that mate with an internally splined guide rail of the cylindrical body that contains both the nut and the drive screw. The reciprocating nature of the guide teeth of the nut and the internally splined guide rail of the cylindrical body translate the rotational motion of the drive screw into linear motion of the nut body. The inverted spline rail system is protected from its operating environment by a seal.Type: GrantFiled: November 28, 2011Date of Patent: April 5, 2016Assignee: Pacific Bearing CompanyInventors: Robert Schroeder, Jonathan R.

Patent number: 8376617Abstract: An improved sliding bearing apparatus and method utilize a snap-in polymer bearing insert having one or more identically shaped locking lugs, each of which are configured for locking engagement with a corresponding depression in a bearing housing, to thereby lock the bearing insert in place against relative movement either radially or axially with respect to the bearing housing. In a free-standing state, the insert may have a variety of shapes including cylindrical, non-cylindrical, or be flat and planar. An insert for a closed bearing is configured such that it may be trimmed to form an insert for an open bearing.Type: GrantFiled: April 4, 2007Date of Patent: February 19, 2013Assignee: Pacific Bearing CompanyInventors: Jonathan R.
