摘要： A loading cam device is constructed of a first cam surface, a second cam surface, a ring-shaped retainer disposed between the first and second cam surfaces and defining pockets at angular intervals, and rolling members maintained in contact with the first and second cam surfaces while rotatably held within the respective pockets. The circumferential width of each pocket is smaller at each side of the retainer but greater along a thicknesswise central axis of the retainer, both compared with the outer diameter of the rolling members. As an alternative, the thickness of the retainer is a little smaller at a location adjacent to each pocket but significantly smaller at a location remote from the pocket, both compared with the thickness the outer diameter. As a further alternative, springs are disposed between surface portions of the retainer, said surface portions being on opposite sides of the retainer, respectively, and being located between each two adjacent pockets, and the first and second cam surfaces, whereby the springs resiliently urge the retainer in directions away from the first and second cam surfaces, respectively.

摘要： An outboard motor is provided that can include an exhaust guide, a shift shaft, a shift shaft rotating mechanism, and a shifting mechanism. The exhaust guide, on which an engine can be mounted, can be utilized to fix the relative positions of an axis of the shift shaft and a body of the shift shaft rotating mechanism for facilitating highly accurate and well-executed shifting of a propeller to or from one of forward and reverse rotating directions. The shift shaft can be rotatably supported by the exhaust guide, and the shift shaft rotating mechanism can be fixed to the exhaust guide. Further, the shift shaft rotating mechanism can be configured to selectively rotate the shift shaft.

摘要： In a toroidal type continuously variable transmission, first pivot shafts provided on both ends of first trunnions are supported within support holes formed in yokes secured to an inner surface of a casing. The support portions are provided with ball splines and radial needle bearings. During operation, loads acting on the first trunnions are canceled within the yokes. Axial displacements and rocking displacements of the first trunnions are effected smoothly by the ball splines and the radial needle bearings.

摘要： A friction-roller speed changer has three intermediate rollers (12a, 12b, 12c). Two rollers (12a, 12b) of which act as a wedge roller and can be moved into the narrower area of an annular space (10) by the transmission of power, wherein during power transmission from the input side in the normal state to the output side. The other intermediate roller (12a or 12b), which does not act as the wedge roller, moves into the wider area of the annular space (10) against the elastic force of the spring (14) whereby transmission efficiency for bidirectional rotation is maintained while preventing backflow of power.

摘要： A toroidal type continuously variable transmission is arranged to support one disc on the input side, facing a pressure device, on the outer circumference of an input shaft through a needle bearing. The other disc on the input side is supported on the input shaft by means of a spline coupling and a flange. A cam board which constitutes a pressure device is supported on the outer circumference of the input shaft through a ball spline. Disc springs are installed between one face of the cam board and a loading nut. In this way, the number of difficult processing steps and the degree of required precision can be reduced at the same time, hence making it possible to implement the reduction of the manufacturing costs.

摘要： An input shaft of a toroidal-type infinitely variable transmission is supported at opposite ends by respective bearings which are secured to a housing, and input and output disks and power rollers are mounted at an intermediate portion of the input shaft. The input shaft has a flange at one end which is connected to an engine, and a pressure adjusting Belleville washer is interposed between the inner end face of the flange and the outer end face of the bearing to bias the input shaft in the direction of the engine so that a predetermined pressing force is applied to the input and output disks and the power rollers during a period in which a small input torque is transmitted to the input shaft. As the input torque increases, the input shaft is moved axially together with a loading cam against the spring force of the Belleville washer, and the inner end face of the flange and the outer end face of the bearing directly abut each other so that a required reaction force is obtained. In this case, since a needle-shaped roller bearing is interposed between the inner peripheral surface of the bearing adjacent the flange and the outer peripheral surface of the inmput shaft, the sliding movement of the input shaft in the axial direction encounters a small frictional resistance.

摘要： A transmission control apparatus for an infinitely variable transmission in which a transmission operating amount is selected by a transmission operating amount selecting system from a memory stored table based on transmission control information from transmission control information detectors which detect the transmission control information such as a throttle opening position command signal, etc., and a driving motor which enables the transmission operation of the infinitely variable transmission to be controlled in an open-loop fashion by a transmission control system in accordance with the transmission operating amount. The transmission operating amount selected by the transmission operating amount selecting system is compared with a predetermined set value by a transmission operating amount decision system to decide whether or not the transmission operating amount is equal to or larger than the predetermined set value, and based on the decision result, the driving motor is driven to rotate by a driving speed selecting system such that, for example, at the time of usual transmission in which the operating amount is small, the driving motor is driven at a low speed, whereas at the time of rapid acceleration or kick down in which the operating amount is large, the driving motor is driven at a high speed.
