  • In-transit mixing machine drive
    Patent number: 8967878
    Abstract: An in-transit mixing machine drive (2) having an output bearing (8) for supporting an output shaft for rotation relative to a drive housing, in which the output shaft is arranged inclined relative to a horizontal plane (5) at an angle (?) and the output bearing (8) is formed by a pendulum roller bearing (9) whose rolling bodies (13, 14) roll in two bearing rows (10, 11) at pressure angles (?, ?) about a bearing axis (12). The pressure angles (?, ?) of the two bearing rows (10, 11) differ from each other or the rolling bodies (13, 14) of the two bearing rows (10, 11) differ from each other.
