摘要： PURPOSE: To facilitate phase adjustment of a gear tooth by constituting a gear train in the first/third stages of a paired helical gears and that in the second stage of a paired bevel gears, also providing a gear coupling of adjusting a phase of a tooth in an intermediate shaft. CONSTITUTION: When a slide gear 15 is moved in an axial direction of the first intermediate shaft 4, an internal gear 23 is rotated by action of a helical gear 18 provided in the gear 15 and a helical tooth 24 formed in the internal gear 23. Through a flange 6b integrally connected to this gear 23, turning force is transmitted to a gear 6, to give a preload to a gear train in the first stage constituted of a helical pinion provided in an input shaft and of the helical gear 6 provided in a plurality of the first two intermediate shafts 4. As a result, a phase is adjusted such that a tooth of a gear train in the first stage is completely meshed into contact. Since a gear train in the second stage, transmitting an output of the first intermediate shaft 4 to the second intermediate shaft 8, is constituted of a bevel pinion 7 provided in the shaft 4 and of a bevel gear 9 provided in the shaft 8, the preload given to the gear train in the first stage is accurately transmitted to the gear train in the second stage.

摘要： PROBLEM TO BE SOLVED: To provide a vertical pump requiring only a small setting area or setting space so as to minimize the building cost of a civil engineering structure, and capable of varying the rotating speed. SOLUTION: A reduction gear 2 connected to a horizontal shaft type gas turbine 1 is fixed to the foundation of a building, and a pump is suspended through a hole provided on the foundation of the building. At this time, the gas turbine 1 is integrally mounted on the reduction gear 2, and the output shaft of a single-shaft gas turbine 1 is connected to the input shaft 8 of the reduction gear. The rotating axial direction of the gas turbine 1 is changed to a right angle by the reduction gear 2 and conformed to the pump flow direction. The reduction gear 2 is divided to two systems by two gears 10A, 10B engaged with an input shaft gear 9. These systems are a speed reduction system consisting of intermediate shaft 11A, 11C, a clutch 24A and a second stage small gear 12A, and a speed reduction system consisting of intermediate shafts 11B, 11D, a clutch 24B and a second-stage small gear 12B. Thus, two-stage speed reduction can be performed even by use of the single-shaft type gas turbine.

SOLUTION: This transmission concerned is used in a high depth underground draining device or the like, and is embodied in such a configuration that the power of a prime mover transmitted to an input shaft 1 is decelerated by a first stage gear train consisting of bevel gears while its direction is changed from the horizontal into vertical, further decelerated by a second stage bevel gear train and followings, and transmitted to a driven machine such as a pump through the output shaft 2. Slide bearings 20 and 21 are used as bearings belonging to the first stage gear train.

摘要： PROBLEM TO BE SOLVED: To aim at size-reduction and capacity increase in such device as driving a pump by means of power of a prime mover via a transmission so as to exhaust underground water by achieving speed reduction of a transmission by means of the first step bevel gear train and also changing its direction from its horizontal line to vertical line so as to make speed reduction by means of the second step planetary gear train. SOLUTION: When the rotation of a prime mover is transmitted to an input shaft 1 via a coupling 5, this power is reduced in its rotational speed by means of the first step bevel gear train composed of a bevel pinion 3 and a bevel gear 6 and the direction of its shaft is changed to vertical line from its horizontal line so as to be transmitted to an intermediate shaft 4. The rotation of the intermediate shaft 4 is transmitted to a sun gear 7 making the second step of a planetary gear train and the rotation of the sun gear 7 is transmitted to an output shaft 2 via a planetary gear 9. The rotation of this output shaft 2 drives a pump shaft so as to suck up the underground water by means of a pump. Since this transmission is formed in a two steps speed reduction structure of such relationship as bevel gear-planetary gear, a distance from the shaft end of the input shaft to the center of the output shaft can be made small so as to provide compactness of a pump machine site.
