摘要： A sealing collar is provided on a body in which the body has a cylindrical wall on which a hole emerges and a fluid situated in the body is able to escape through the hole. The sealing collar includes a fixing band entirely surrounding the cylindrical wall. The fixing band has a sealing portion to sealedly obturate the hole and a means for closing and tightening the fixing band. The fixing band is provided with at least one claw extending in the direction of the cylindrical wall so that on closing and tightening of the fixing band around the cylindrical wall, the hole is sealedly obturated and the claw is pressed against the cylindrical wall and contributes to immobilizing the sealing collar on the body.

The harmonic gear drive unit includes a circular spline and a dynamic spline, a flexspline disposed radially within the circular spline and the dynamic spline, a wave generator disposed radially within the flexspline, and a rotational actuator connectable to the wave generator. One of the circular spline and the dynamic spline is fixed to the housing. A hub is rotatably disposed radially within the housing and attachable to the camshaft and fixed to the other of the circular spline and the dynamic spline. An anti-rotation means is provided for temporarily fixing the circular spline to the dynamic spline in order to prevent relative rotation therebetween when the hub is being attached to the camshaft. The anti-rotation means prevents damage to the harmonic gear drive unit while the camshaft phaser is being installed onto the camshaft.

摘要： A camshaft phaser controllably varies the phase relationship between a crankshaft and a camshaft in an internal combustion engine. The camshaft phaser includes an input member rotatable by the crankshaft. The input member is connected through a gear drive to an output member which is fixed to the camshaft. A rotational actuator acting on the gear drive unit causes relative rotation between the input member and the output member. A first stop member is rotatable with the input member in a one-to-one relationship. A second stop member is rotatable with the output member in a one-to-one relationship to limit relative angular travel between the input member and the output member. A torque absorption means is provided for limiting the rate at which torque is applied from the rotational actuator to the gear drive unit when the second stop member makes contact with the first stop member.

摘要： An eVCP camshaft phaser comprising a harmonic gear drive unit having a circular spline and a dynamic spline linked by a common flexspline, and a single wave generator disposed within the flexspline. The circular spline is connectable to either of a crankshaft-connectable sprocket or an engine camshaft, the dynamic spline being connectable to the other thereof. The wave generator is driven selectively by an eMotor to cause the dynamic spline to rotate past the circular spline, thereby changing the phase relationship between the crankshaft and the camshaft. A coaxial coil spring is connected to the sprocket and to the phaser hub and is positioned and tensioned to bias the phaser and camshaft to a stop position wherein the engine can run or be restarted after the eMotor is de-energized. Preferably, the spring comprises a spring cassette for easy assembly into the eVCP.

摘要： Improved stiffening and minimized distortion of a housing for an eVCP achieved by forming a plurality of radial housing stiffeners into the housing around the motor mount end and into the eVCP's hub. A back plate is press fit into the rear of the housing, and a straight axial knurl is applied to the surface of the back plate or housing, which knurl permits a larger tolerance-higher press fit class to be used without resulting in significant deformation of the housing. The knurled back plate is harder than the housing, causing the high points of the knurl to plastically deform or plow the housing material during assembly, resulting in less radial deformation of the bore and the journal bearing. An interface between the housing and the hub provides a journal bearing interface to improve axial stability between the hub and housing.
