摘要： The present disclosure relates to a cover element for a camshaft phaser and a camshaft phaser. The cover element includes a journal and a cover plate, the journal is used to form sealing engagement with an oil seal, and the journal and the cover plate are connected by welding. A positioning portion is formed on the surface of the cover plate for positioning the journal. The cover element is formed by welding the cover plate and the journal, which are processed separately, so as to conveniently perform different processing of the cover plate and the journal. A positioning portion for positioning the journal is formed on the surface of the cover plate so as to easily position the journal during the welding process, which enables the journal and the cover plate to be easily welded together without requiring complicated fastening. This improves processing efficiency and reduces production costs.

摘要： A device for adjusting camshaft phase is proviced that includes a stator, a rotor and two guard caps that limit the rotor are fixedly provided at axial ends of the stator. The device further includes a belt pulley that is sleeved on the periphery of the stator and the guard caps and fixedly connected to the stator or the guard caps. An annular seal is disposed on the device and includes a first sealing portion and a second sealing portion located at axial ends. The seal body is fixedly provided between the stator, the guard caps and the belt pulley, and the annular seal encloses a sealed cavity. The stator, the rotor and the guard caps are fixedly provided in the sealed cavity.
