Abstract
The utility model discloses a variable valve timing executive device which comprises a belt pulley. A rotor is arranged in the belt pulley; blades are arranged on the rotor; the outer end surface of the belt pulley is connected with an outer baffle plate; the outer baffle plate is connected with an end cover; a sealing ring is arranged between the outer baffle plate and the end cover; the inner end surface of the rotor and the inner end surface of the belt pulley are in an identical plane; the end surface of the belt pulley is connected with an inner baffle plate; the diameter of the inner baffle plate is larger than that of the belt pulley; oil cavities corresponding to the blades are formed by the inner cavity wall of the belt pulley, the side surface of the rotor, and the cavity between the inner end surface of the inner baffle plate and the inner end surface of the outer baffle plate; the upper parts of the blades are arranged in the respective oil cavities; oil ducts are arranged on the rotor and respectively communicate with the oil cavities; sealing rings are arranged between the contact surfaces of the belt pulley and the baffle plates, and between the contact surfaces of the belt pulley and the outer baffle plate. On the one hand, the inner baffle plate plays a role in sealing the baffle plates, and on the other hand, the inner baffle plate plays a role in limiting the baffle plates by preventing a belt from axially moving; therefore, parts are reduced, and the cost is reduced.
Description
Technical field
The utility model belongs to auto parts and components, is specifically related to a kind of Variable Valve Time actuating device.
Background technique
Chain or belt transmission are generally adopted in present motor transmission, the driving mechanism belt pulley must seal when the bel-drivenn motor adopted the Variable Valve Time phase techniques, the belt pulley both sides must charge of oil block plate like this, simultaneously because belt is easy to generate axial float when running up, need add a baffle plate and prevent its axial float, need two parts like this, two baffle plates can't be installed on camshaft simultaneously, part producer is preventing that the baffle plate of belt axial float is installed on the bent axle.Increase component and cost like this.
Summary of the invention
The Variable Valve Time actuating device that provides a kind of part few is provided the purpose of this utility model, to address the above problem.
The technical solution of the utility model: Variable Valve Time actuating device, it comprises belt pulley, establish rotor in the belt pulley, establish blade on the rotor, the belt pulley exterior edge face connects exterior siding, and exterior siding connects end cap, establish seal ring between exterior siding and the end cap, the interior edge face of rotor and belt pulley interior edge face are in same plane, and the belt pulley interior edge face connects internal baffle, and the diameter of internal baffle is greater than the diameter of belt pulley; Cavity between the internal chamber wall of belt pulley, rotor side surface and internal baffle interior edge face, the exterior siding interior edge face constitutes and the corresponding oil pocket of blade, and blade top is located in separately the oil pocket, establishes oil duct on the rotor and communicates with oil pocket respectively; Between belt pulley and the baffle plate surface of contact, be provided with seal ring between belt pulley and the exterior siding surface of contact.
The utility model is located at the interior edge face and the belt pulley interior edge face of rotor in the same plane, connect the diameter internal baffle bigger at the belt pulley interior edge face than diameter pulley, play the effect of sealing baffle on the one hand, prevent that on the other hand the belt axial float from playing the effect of defining baffle, reduce part like this, reduce cost.
