This feature leads to the disadvantage that, if the components are heated prior to the assembly process, the time required to position each component in a predetermined position, coupled with the requirement to position the housing in a predetermined position with respect to the components to be mounted on the shaft, means This means that previously heated components need to cool down before the assembly process begins
Thus will obstruct the passage of the shaft through the opening of the element to be mounted, slowing down the assembly process and possibly causing misalignment of many components

Embodiment Construction
[0018] figure 1 A composite housing is shown equipped with shafts and associated mounting elements, assembled using the assembly method according to the invention.
[0019] In the example shown, the housing 10 is a cylinder head cover of an automotive (not shown) engine and includes first and second end walls 12 , 14 and at least one intermediate wall 16 . Housing 10 may alternatively be open, suitable for forming part of a cylinder head of an engine. Additional intermediate walls 16 may be provided depending on the size of the housing. In the example shown, one intermediate wall is provided, generally equidistant from the two end walls 12,14.
[0020] The end walls 12, 14 and the or each intermediate wall 16 are generally provided with annular bearings 18 which are preferably similar and adapted together to receive a shaft 20, as will be described below. The shaft 20 is provided with mounting elements 22 at intervals along the length, four in the example shown. In the exa...

A method of assembling a composite housing provided with a shaft (20) and associated mounting elements (22), comprising the steps of arranging the housing (10) in a predetermined position relative to an actuator (28), the housing having at least one opening (18), which is adapted to receive the shaft (20); arrange the shaft (20) in a predetermined position relative to the housing (10) and the actuator (28); select the shaft to be installed in the housing (10) The element (22) on (20), the element (22) has an opening suitable for receiving the shaft (20); carries the element (22) to a predetermined position in the housing (10), and by means of the actuator (28) Pushing the shaft (20) allows the shaft to fit continuously through the openings of the housing (10) and element (22). According to the invention, the method further comprises the step of: after selecting the element (22) to be mounted on the shaft (20) in the housing (10) and before carrying the element to a predetermined position in the housing, the element Hold in place adjacent to the heat source (36) for a predetermined time. A device for assembling the composite shell is also described. The invention finds an application in the automotive sector, the composite housing comprising the cylinder head cover of an automotive engine.
Description
technical field [0001] The invention relates to a method and a device for assembling a composite housing equipped with a shaft and associated mounting elements. Background technique [0002] In many fields, especially in the automotive field, it is necessary to equip the housing with a rotatable shaft on which a number of mounting elements are positioned along the length. In order for the shaft to be rotatably positioned on the bearings arranged in the housing, it is necessary that the shaft is driven continuously through each bearing and each mounting element, which are positioned in advance along the path of the shaft . [0003] In case the assembly schematic is applied in the automotive sector, the composite housing may comprise a cylinder head cover of an automotive engine, the mounting elements serving as cam lobes during operation of the associated valve train in the engine. In addition, other elements, such as counterweights, can be installed to ensure vibration-fre...
