Claims

[Claims for Utility Model Registration] The bases of a plurality of propeller fans are connected in the radial direction of a support member which is fixed to the upper part of a tube shaft that is vertically pivoted to the main body and driven by a motor. The lower end of the control shaft, which is mounted rotatably within a range and can be raised and lowered and inserted through the tube shaft, is connected to a pressure cylinder fixed to the bottom of the main body, and a flange fixed horizontally to the upper end of the control shaft. and the support member, a spring device acting in a direction opposite to the action of the pressure cylinder device is provided, and the flange and the base of the propeller fan are linked by a crank mechanism,
A device that changes the pitch of the propeller fan by rotating the base of the propeller fan via a link mechanism according to the difference between the acting force of the pressure cylinder and the acting force of the spring device, which changes depending on the set pressure. The base of the propeller fan is fixed to the outer end, and the short shaft linked to the flange via a link mechanism is arranged in the radial direction of the support member, and the base part of the propeller fan is fixed to the outer end, and the short shaft is arranged in the radial direction of the support member, and A support mechanism for a propeller fan for an air-cooled heat exchanger, characterized in that the short shaft is supported by rolling bearings arranged at respective positions to receive radial and thrust loads.
