Drive for auxiliary unit, especially hydraulic pump on internal combustion engine, includes belt drive wheel connected to splined shaft by pressed connection, with bore interacting with tooth points of splined shaft

摘要

The belt drive wheel for the auxiliary unit is connected to a splined shaft(10) by a pressed connection and in the region of this connection has a bore(9) interacting with the tooth points of the splined shaft. The tooth points in the region of the pressed connection have a larger external diameter than in the region of the rest of the splined shaft, and are conical in shape. The slide-on socket joint(18) connecting the auxiliary unit to the splined shaft is sealed in relation to it by means of a packing(20).
