Definitions
- Rotor in particular for a camshaft adjuster, method for producing a rotor and device for adjusting the rotational angle of a camshaft relative to a crankshaft of an engine
- the invention relates to a rotor, in particular for a camshaft adjuster, comprising a rotor base body having a hub part with a central oil supply, at least one radially arranged on the hub part wing and through the hub part on both sides of each wing, fluidly connected to the central oil supply oil passages.
- a rotor is e.g. known from DE 199 38 596 A1.
- the invention further relates to a method for producing such a rotor and to a device for adjusting the rotational angle of a camshaft relative to a crankshaft of a motor having such a rotor.
- camshafts are used to actuate the gas exchange valves.
- the cams of the camshafts are usually on cam followers, such as bucket tappets, rocker arms or rocker arms. If a camshaft is rotated, the cams roll on the cam sequences, which in turn actuate the gas exchange valves. Due to the position and the shape of the cams thus both the opening duration and the opening amplitude, but also the opening and closing times of the gas exchange valves are fixed.
- camshaft adjustment The angular displacement of the camshaft with respect to a crankshaft to achieve optimized timing for different speed and load conditions. de is referred to as camshaft adjustment.
- a constructive variant of a camshaft adjuster works, for example, according to the so-called swing motor principle.
- a stator and a rotor are provided, which are coaxial and are movable relative to each other.
- the stator and the rotor together form hydraulic chambers, here simply called chambers.
- a pair of chambers is here each bounded by webs of the stator and divided by a respective wing of the rotor into two mutually opposite chambers whose volume is changed in opposite directions by a relative rotational movement of the rotor to the stator.
- the respective wing bears against one of the edge-side webs of the stator.
- the relative rotational movement of the rotor is effected by an adjustment of the wing by a hydraulic medium such as oil is introduced via channels in the chambers and pushes the wing.
- a hydraulic medium such as oil is introduced via channels in the chambers and pushes the wing.
- the camshaft attached to the rotor is adjusted, for example, in the direction of early, ie a previous opening time of the gas exchange valves.
- the camshaft with respect to the crankshaft toward late, ie a later opening time of the gas exchange valves adjusted.
- the hydraulic medium from a central oil supply is guided into the respective chamber via oil passages, which are arranged on both sides of the respective wing.
- the oil channels represent, for example, holes in the material of the rotor, their training is complex.
- the invention has for its object to simplify the production of a rotor.
- a rotor in particular for a camshaft adjuster, comprising a rotor base body having a hub part with a central oil supply, at least one radially on the hub part having arranged wings and through the hub part on both sides of each wing extending, fluidly connected to the central oil supply oil passages, the rotorg round body is divided along a dividing plane and has two main body parts.
- the invention is based on the idea that the production of a rotor is optimized by the Rotorg round body is composed of at least two main body parts which are firmly connected to each other in a parting plane. It is also possible that more than one dividing plane is provided, e.g. that the Rotorg round body is divided along two parting planes, so that the Rotorg round body comprises a total of three basic body parts, which are joined together. Thanks to the multi-part design of the rotor body in an early production step, each of the body parts has a relatively small volume and a simplified geometry, which makes its manufacture easier.
- the Rotorg round body is usually formed as a sintered body. In this case, first a green body made of pressed powder, in particular metal powder, is produced and then sintered. Due to the division of complex geometries of the rotor body can be formed by appropriate shaping of the individual body parts in a simple manner without additional post-processing operations.
- round bodies are provided in the rotor body.
- the cavities ensure a reduction in the weight of the rotor base body, so that a high mass moment of inertia is avoided on the one hand and, on the other hand, less material is required for the production of the rotor body.
- the cavities are preferably formed as a closed cavities within the Rotorg round body.
- the cavities are preferably formed in the hub part.
- the hub part usually has a larger volume than the wings and it is thus more space for the formation of cavities available.
- the cavities are arranged, for example symmetrically about an axis of rotation of the rotor body.
- a substantial weight reduction of the rotor is achieved by the area of the cavities (perpendicular to a rotation axis of the rotor) expediently being approximately 1/3 to 2/3 of the area of the hub part between two wings.
- the depth of the cavities extends in the direction of the axis of rotation except for a thin, the cavity axially outwardly closing wall over the entire axial length of the rotor body.
- the oil passages are arranged in the dividing plane.
- the oil passages are formed in particular as groove-shaped material recesses on the surface forming the parting plane of at least one main body part.
- the oil passages are located inside the rotor body.
- a Materialaussparrung is provided to form a respective oil passage only in one of the body parts.
- the rotor base body preferably has an axis of rotation and the dividing plane is perpendicular to the axis of rotation. Due to the formation of the dividing plane perpendicular to the axis of rotation, in particular the formation of radially extending channels as well as of cavities, which likewise lie in the dividing plane, is simplified.
- the dividing plane divides the rotor main body in the center and the main body parts form two halves of the rotor main body.
- This embodiment of the basic body parts is particularly advantageous in terms of production since both basic body parts of the rotor body are manufactured with the same tool.
- the two halves are identical.
- the production of only one type of body parts is required. Two such main body parts are placed on each other to form a rotor main body mirror image and assembled.
- each wing is associated with exactly one oil channel in each basic body part.
- This embodiment of the basic body parts is associated with a particularly small processing effort, since per wing in the main body part a single material recess is introduced for an oil passage. If two main body parts are joined together in mirror image form, the oil channel formed in the respectively opposite basic body part is located on the other side of the blade. Thus, there are two oil channels to the respective chamber on both sides of the wing.
- connection of the two halves is realized in a simple manner, in particular by a positive connection.
- the two halves are connected to each other via pins.
- Such pins usually have a simple geometry and are particularly easy to manufacture.
- the pins form an integral part of the basic body parts and are formed in a production step with the respective basic body part.
- Each body part body is provided in accordance with a number of journal receptacles, which corresponds to the number of pins. If two such body parts are placed mirror images of each other, while the pins of one of the basic body part are inserted into the journal receptacles of the respective opposite base body part.
- the rotor base body is expediently designed as a sintered body.
- the object is further achieved according to the invention by a method for producing a rotor according to one of the preceding embodiments, in which at least two basic body parts are manufactured for the rotor base body and firmly connected to one another in a dividing plane.
- the basic body parts are produced as two identical halves and then joined together.
- the main body parts are sintered after assembly, whereby the rotor body is formed.
- the rotor base body is thus produced in a sintering process.
- the basic body parts are formed individually in a first production step as so-called green bodies, in particular from metal powder pressed into the desired shape.
- the two halves are then assembled in a second production step to form a closed, in particular provided with the cavities rotor body and compacted in the sintering process by heat treatment and cured.
- the main body parts are also manufactured by casting and connected to each other, for example, by soldering, welding or gluing.
- a device for adjusting the rotational angle of a camshaft relative to a crankshaft of a motor with a rotor according to one of the preceding embodiments.
- the advantages and preferred embodiments stated with regard to the rotor can be analogously transferred to the method and the device for rotational angle adjustment, which for the sake of simplicity is referred to as a camshaft adjuster.
