A bearing block comprises a camshaft in an internal combustion engine and a valve drive. The valve drive may include at least one rocker arm mounted on a rocker arm shaft, wherein the bearing block is formed concurrently with the mounting of the at least one rocker arm.
First claim
Opening claim text (preview).
The invention claimed is: 1. A bearing block system comprising: a camshaft in an internal combustion engine, a valve drive including at least one rocker arm mounted on a rocker arm shaft, wherein the bearing block system further includes a single piece block having a bearing eye, and the rocker arm shaft is one of press fit and thermally joined in the bearing eye; wherein the single piece block has an annular opening configured to mount the camshaft therein and the single piece block is a single material that includes the annular opening and extends from the bearing eye to the annular opening. 2. The bearing block system according to claim 1 , further comprising a rolling bearing disposed between the single piece block and the camshaft. 3. The bearing block system according to claim 1 , wherein the rocker arm shaft is thermally joined to the bearing eye by way of cooling the rocker arm shaft and heating the single piece block. 4. A prefabricated valve drive unit comprising: at least one camshaft, at least two single piece blocks and a rocker arm shaft, wherein each one of the single piece blocks has a bearing eye, and the rocker arm shaft is one of press fit and thermally joined in the bearing eye of each single piece block; wherein each one of the single piece blocks has an annular opening configured to mount the at least one camshaft therein, and each one of the single piece blocks is a single material that includes the bearing eye and extends from the bearing eye to the annular opening. 5. The prefabricated valve drive unit according claim 4 , further comprising a rolling bearing disposed between each single piece block and the at least one camshaft. 6. An internal combustion engine comprising: at least two single piece blocks and at least one prefabricated valve drive unit, wherein the drive unit includes at least one camshaft, at least two single piece blocks and a rocker arm shaft, wherein each one of the single piece blocks has a bearing eye, and the rocker arm shaft is one of press fit and thermally joined in the bearing eye of each single piece block; wherein each one of the single piece blocks has an annular opening configured to mount the at least one camshaft therein, and each one of the single piece blocks is a single material that includes the bearing eye and extends from the bearing eye to the annular opening. 7. The internal combustion engine according claim 6 , further comprising a rolling bearing disposed between each single piece block and the at least one camshaft.
