A connection for a rotating machine according to an exemplary aspect of the present disclosure includes an interface axially between and adjacent to a first interference fit and a second interference fit.
Abstract:
A parallel eccentric electro-mechanical actuator provides motive power and includes an electric prime mover that drives the reducer's pinion gear. This pinion drives minimum three star gears with stationary shaft bearings. Each shaft contains an eccentric which are completely in parallel with each other. These eccentrics can be thought of as parallel/in-phase driven crankshafts. Each eccentric drives the parallel eccentric (PE) gear through a bearing. The PE gear exhibits a circular motion (without rotation) which in itself is unbalanced. The crankshafts have another eccentric which create an opposite inertia force to balance that of the PE gear. The PE gear contains an external toothed gear on its periphery. It meshes with the internal teeth of the output ring gear. The relative motion between the PE gear and the ring gear is that the PE gear rolls inside the ring gear. This relative motion is called hypo-cycloidal motion.
Abstract:
A gear assembly may include first and second gear wheels meshing with each other and having a meshing line. The meshing line is formed as a combined line that is positioned between first and second curves to determine a meshing range of the meshing line, so as to extend from a point on the first curve positioned radially inside the second curve in a circumferential direction in which the second curve is radially outwardly spaced from the first curve and to reach a point on the second curve. The combined line is composed of a combination of a plurality of line portions.
Abstract:
A drive gear includes a plurality of internal radial channels extending between the axial bore and the periphery of the gear, and an axial bore includes a lubricant distribution structure therein to provide lubrication where the teeth of the drive gear mesh with the teeth of a gear driven by the drive gear.
Abstract:
In a gear mechanism, inner gear teeth and outer gear teeth are formed of high-tooth. An engagement ratio of the inner and outer gear teeth is configured so as to be 2.0 or more, whereby a load can be transferred between the inner and outer teeth via a continuous gear engagement of at least two pairs of gear teeth thereof. Accordingly, a contact face pressure and a bending stress occurring to inner and outer gear teeth can be reduced, the limitation of the durability of the gear mechanism due to the large difference of durability between the inner and outer gear teeth can be improved, and the necessity of increasing hardness of the inner gear teeth can be lessened.
Abstract:
To make a throttle valve control device compact, by reducing a longitudinal directional length H and a side directional length L of a gear part comprising a motor gear, an intermediate gear and a drive gear, so as to improve mountability on a two-wheeled vehicle, a drive gear Ka is provided at a throttle valve shaft 3, a motor gear Ma is provided at a motor M, the motor gear Ma is geared with a large diameter gear Nb of an intermediate gear Na, the drive gear Ka is geared with a small diameter gear Nc of the intermediate gear Na, the large diameter gear Nb of the intermediate gear Na is formed as an internal gear Nf, and the motor gear Ma is geared with the internal gear Nf which is the large diameter gear Nb.
Abstract:
A discontinuous linear drive comprises a guiding component and an engaging means. The engaging means engages in a member to be driven and guided by guiding components in at least two places by means of a respective movable engaging component. The member to be driven is driven by a phase-shifted effecting and releasing of the engagement of the moved engaging components.
Abstract:
An outer member and an inner member are drivingly connected at a toothed interface. The members are restrained from axial separation by a retaining ring. The retaining ring is engaged in a groove formed in the inner member and has a pair of tabs which extend radially outward through slots in the inner member. The tabs abut an end face on the outer member thereby preventing relative axial displacement of the inner and outer members.
Abstract:
A reclining device comprises a stationary base fixedly connected to a seat cushion, a pivotal, press-worked arm fixedly connected to a seat back and rotatably supported on the base and having an inner toothed portion, at least one toothed block slidably disposed between the base and the arm and having an outer toothed portion meshable with the inner toothed portion, and a rotary cam in cam-connection with the toothed block for producing an outward or inward sliding motion of the toothed block to mesh or unmesh the outer toothed portion with or from the inner toothed portion by rotation of the cam. To balance two contradictory requirements, that is reduction of undue sink mark (lack of fill) and high mechanical strength (high durability), a reinforced portion of a lack-of-fill suppressive geometry and shape, being composed of at least two outside curved faces, is integrally formed with the arm all around the circumferentially-extending stepped portion on an arm outside face opposed to an arm inside face formed with the inner toothed portion.
Abstract:
An improved, blocked, change gear transmission utilizing at least one improved resilient jaw clutch assembly to selectively engage a selected gear to a shaft is provided. The improved jaw clutch assembly comprises two axially engageable jaw clutch members and a blocker mechanism to prevent engagement of the jaw clutch members until the jaw clutch members are rotating at a substantially synchronous speed. Preferably, one of the jaw clutch members carries axially and radially outwardly extending external clutch teeth designed for selective interengagement with axially and radially inwardly extending internal jaw clutch teeth carried by the other jaw clutch member. The improvement comprises providing a back-lash between the interengageable clutch teeth which is substantially greater than the back-lash normally utilized with similar clutch assemblies, said increased back-lash being in the range of five to fifteen times greater than normal back-lash and preferably about ten times greater than normal back-lash.
