摘要： The door or doors of an elevator are driven through their opening and closing cycles by one or more linear induction motor (LIM) assemblies in which the primary winding component of the LIM assembly is secured to the elevator cab structure and the LIM secondary component is secured to the cab door. If the cab has two oppositely moving doors, there will preferably be two separate motor drives, one for each door. In one embodiment, the motor components are arranged so as to create a normal force which is horizontal; and in another embodiment, the normal force created is vertical. A primary motor mount bracket is used which secures the primary winding component to the overhead component of the cab structure.

摘要： When an elevator is running, the car door 27 is locked in the closed position by a brake shoe 12 which engages the edge of the door hanger 24 in response to a push-type solenoid 19 overcoming the force of a spring. When the door is not closed, a friction brake pad 11 contacts the door hanger surface to hold the door open for passenger boarding or to stop the door in case of failure of door operator power while the door is in motion.

摘要： A gripper and mandrel assembly for a tube bender, particularly a bender of the stretch type. At least two gripper jaws close about an end of a tubular workpiece when actuated by the cone portion of a slideable shaft. The same shaft has a cable and ball type mandrel extending outwardly from its distal end. During a stroke of the shaft from the DISENGAGE to the ENGAGE position of the assembly, the shaft both drives the mandrel into the workpiece and also causes the jaws to close about the end of the tube. When in the ENGAGE position, the distal end of the shaft is inside the tube in order to prevent the gripper jaws from deforming or otherwise causing excessive damage to the workpiece end. An abrasive coating partially covers the inner surface of the recess of the gripper jaw that contacts the outer wall of the workpiece in order to insure a firm grasp of the workpiece by the gripper jaws. A tube bender would have at least two assemblies, one to grasp each end of a tubular workpiece.
摘要翻译： 用于弯管机的夹具和心轴组件，特别是拉伸型弯曲机。 当由可滑动轴的锥形部分致动时，至少两个夹钳爪围绕管状工件的端部关闭。 相同的轴具有从其远端向外延伸的电缆和球型心轴。 在从DISENGAGE到组件的ENGAGE位置的轴的冲程期间，轴将心轴驱动到工件中并且还使得夹爪围绕管的端部闭合。 当在ENGAGE位置时，轴的远端位于管内，以防止夹爪卡爪变形或以其他方式对工件端部造成过大的损坏。 研磨涂层部分地覆盖夹持爪的凹部的内表面，该内表面与工件的外壁相接触，以便通过夹持爪确保工件的牢固抓握。 管弯曲机将具有至少两个组件，一个用于抓住管状工件的每个端部。
