Torque reaction arrangement for pulp washers

A torque reaction arrangement for twin press-roll pulp washers, comprising:

• a first torque reaction arm;
• a second torque reaction arm;
• a first link;
• and
• a second link;
• wherein:
• a first end of said first torque reaction arm comprises first mounting means for enabling rigid mounting of said first torque reaction arm to a stator of a first press roll motor with a main extension of said first torque reaction arm being transverse to a first extension of a first rotational axis of a rotor of said first press roll motor when being rigidly mounted to said first mounting means;
• a first end of said second torque reaction arm comprises second mounting means for enabling a rigid mounting of said second torque reaction arm to a stator of a second press roll motor with a main extension of said second torque reaction arm being transverse to a second extension of a second rotational axis of a rotor of said second press roll motor when being rigidly mounted to said second mounting means, said first rotational axis being parallel to said second rotational axis;
• said first link connects a first connection of said first torque reaction arm and a first connection of said second torque reaction arm, and wherein said first connection of said first torque reaction arm and said first connection of said second torque reaction arm allow relative turning of said first link relative to said first torque reaction arm and said second torque reaction arm around an axis parallel to said first rotational axis;
• and
• said second link connects a second connection of said first torque reaction arm and a second connection of said second torque reaction arm, and wherein said second connection of said first torque reaction arm and said second connection of said second torque reaction arm allow relative turning of said second link relative to said first torque reaction arm and said second torque reaction arm around an axis parallel to said second rotational axis;
• and
• said first connection of said first torque reaction arm is situated at a second end of said first torque reaction arm, opposite to said first end of said first torque reaction arm, and said second connection of said second torque reaction arm is situated at a second end of said second torque reaction arm, opposite to said first end of said second torque reaction arm;
• a direction between said first connection of said first torque reaction arm and said first connection of said second torque reaction arm differs from a direction between said second connection of said second torque reaction arm and said second connection of said first torque reaction arm by less than 15°;
• a direction between said first connection of said first torque reaction arm and said first connection of said second torque reaction arm differs from a direction between said first connection of said second torque reaction arm and said second extension by less than 15°;
• and
• a direction between said second connection of said second torque reaction arm and said second connection of said first torque reaction arm differs from a direction between said second connection of said first torque reaction arm and said first extension by less than 15°.
