摘要:
A surface textured roller and a surface textured rolling element bearing comprising a plurality of micropores in a surface thereof is presented. The plurality of micropores may have a geometry selected from a hemisphere, a diamond shape, an ellipsoid, and a cone. The surface textured rollers may be used, for example, in a gear box and/or a wind turbine drivetrain.

摘要:
Systems and methods provide variable spring stiffness for weight management in a vehicle. One system includes a plurality of springs and a plurality of spring retainers configured to adjust a number of inactive coils of the plurality of springs. Additionally, a motor is provided that is connected to the plurality of spring retainers and configured to actuate the spring retainers to adjust the number of inactive coils of the plurality of springs. Further, a controller is provided that is coupled to motor to control the motor to actuate the spring retainers to adjust the number of inactive coils of the plurality of springs.
