Method of making an electric drive unit having a gear shaft and rotor shaft with three bearings

A method of assembling an electric drive unit having only three bearings in a rotor shaft and gear shaft portion:

• a first bearing, a second bearing and a third bearing, the method comprising:
• providing a rotor shaft having a first end and a second end, and comprising a first region from the first end to a first shoulder and a second region from the second end to a second shoulder;
• providing a gear shaft having a third end and a fourth end, and comprising a third region from the third end to a third shoulder and a fourth region from the fourth end to a fourth shoulder;
• positioning the second region of the rotor shaft into the first bearing such that the first bearing is adjacent the second shoulder;
• positioning the third region of the gear shaft into the second bearing such that the second bearing is adjacent the third shoulder;
• positioning the fourth region of the gear shaft into the third bearing such that the third bearing is adjacent the fourth shoulder;
• positioning the first region of the rotor shaft into the fourth end of the gear shaft such that the fourth end of the gear shaft is adjacent the first shoulder;
• and
• wherein the third bearing supports the rotor shaft and the gear shaft, and wherein the rotor shaft and gear shaft portion consists of only three bearings.
