As disclosed in Publication No. 50241, in air conditioning equipment, a transmission is provided in the drive path between the electric motor and the water pump or fan, and the gear position of the transmission is changed by feedback control based on temperature detection or timer control. There is a well-known technique for controlling the driving rotation speed of a water pump or a fan by switching the number of rotations. In air conditioning equipment equipped with such a transmission, the energy consumption of fluid transport machines such as water pumps and ventilation fans is proportional to the cube of the rotation speed, which reduces the rotation speed by about 80%.
By lowering the energy consumption to 50%, energy consumption is halved, resulting in a high energy-saving effect.

A taper bushing 9 to be fitted into the taper hole 7 is fixedly installed on the shaft 1a, and a screw rod 10 is attached to the taper bush 9, which is inserted into the through hole 8 and faces outside the other end of the input shaft 4. A nut 11 that abuts the input shaft 4 outside the other end of the input shaft 4 is screwed onto the screw rod 10,
A window hole 12 for operating the nut 11 is formed in the transmission case 3 and covered with a lid 13, while the output shaft 5 is formed in a hollow shape and arranged concentrically with the input shaft 4 on the outer circumferential side of the input shaft 4 for transmission. Provided to protrude from inside the case 3 in the same direction as the one end 4a of the input shaft 4,
A variable speed drive device in which the pulley 6 is loosely fitted onto one end portion 4a of the input shaft and is connected and fixed to the output shaft 5.
