Abstract:
The present invention relates to the transistor type universal driving which has three shafts as transistor, i.e. driving shaft, driven shaft and control shaft and can provide non-step speed reduction, non-step speed increase, overloading adaptation control, automatic and remote control. The structural character of the transistor type universal driving is that the control shaft is suitably combined to the fixed support point of the speed reducer which contains the fixed support point.
Abstract:
An automatic tool changer in which the load produced when a turret is rotation-driven is reduced, and abrasion in the balls and the like of a speed reducer, and mal-distribution of an axial pressing force are prevented. The speed reducer that drives the turret in the automatic tool changer is constructed by superposing a driving plate, a holder, and a driven plate in the order named. In the driven plate fitted with tools, there is formed a ball groove in a concave-convex shape having the number of cycles corresponding to the number of the tools. In the driving plate, there is provided a ball groove obtained by enlarging the ball groove of the driven plate in the angular direction and copying two cycles. The holder is provided with a plurality of guide holes in the radial direction, which hold their respective balls. The driving plate is rotated by spindle rotation, and the driven plate is driven at a reduced speed of (the number of tools/2) through the balls. It is possible to reduce the load by setting the ball groove of the driven plate at the optimum pressure angle. The balls are dispersed, so that the axial pressure is even, to thereby reduce the abrasion of the balls and ball grooves, and the like.
Abstract:
A method is provided for optimally engineering a toroidal transmission having a desired input/output ratio to implement the desired ratio of the transmission while meeting the torque and efficiency requirements of the design. Nanoparticle technology is used to manufacture the stator walls to replace the cutting and milling procedures now in use. A novel Mitchell bearing sleeve and its particular hydrodynamic lubrication and cooling method are proposed herein, as well as the introduction of a novel, ultra smooth, amorphous non-oxidizing contact sleeve material used to form the contact sleeve of the drive rollers. A novel self-lubricating system is further provided that includes an oil reservoir disposed within an output shaft of the transmission.

A simultaneous multiple rotation interface where a series of discs eccentrically rotate about a central shaft to create a speed reduction between an input disc and an output disc. Each disc is engaged with the other via a series of bearings embedded within each disc.
Abstract:
The invention relates to an adjusting device for adjusting two parts (2,3) ith respect to one another that is used as a cam shaft adjuster. The objective of the invention is, with an easy and smooth operability, to ensure a self-locking and an at least extensive paly-free, continuous adjustment of the two parts with a high degree of efficiency. To this end, the adjusting device comprises a first part (2) with webs (2.3, 22.3), which are interspaced in the peripheral direction and between which chambers (2.4) are formed, and includes a second part (3) with an internal gearing (3.2, 13.2), and a number of teeth (7, 27_that are arranged inside the chambers (2.4) while being interspaced in the peripheral direction. The adjusting device also includes an inner contact surface (7.4) for resting against an eccentric drive element (6), and includes an outer contact surface (7.5) for engaging inside the internal gearing (3.2, 13.2). When an imput shaft (4) is rotated by the teeth (7, 27) located inside the chambers (2.4), rotational motions about rotation axes, which are parallel to a rotation axis (A) of the parts (2,3) can be executed.
Abstract:
A multi-speed ratio apparatus to control output for use, but not limited to, either as a module connected to a transmission or as a stand alone transmission. The multi-speed ratio apparatus is connected to a driving member (such as, for example, an engine, motor, or transmission) and a driven member (such as a shaft, differential, or axle). The apparatus having at least one rotary speed converter, the rotary speed converter having a conjugate pair of cam parts and a reaction disk interconnected between the conjugate pair of cam parts. The reaction disk is capable of operably coupling the conjugate pair of cam parts. Further the apparatus includes a grounding member.
Abstract:
The particularly durable internal geared wheel of a harmonic drive is made up of individual, identical, essentially solid radial tappets (21) in a link chain-type arrangement, said tappets each being provided with an elastically radially, compressible hollow head (26) and being flexibly linked in such a way that they can pivot, by means of side connecting profiles (30, 31) which can be connected in pairs. The geometry of the tappets can be produced economically on a large scale by plastic injection moulding a rigid, thermoplastic, low-density material, in a technologically uncritical manner and with a considerable degree of dimensional accuracy, so that an internal geared wheel which can be assembled from different numbers of tappets is also characterised by low mass inertia. each tappet (21) has good sliding friction and wear characteristics and is very dimensionally stable in relation to heat when the foot (23) is radially supported on the drive core, due to the combination of materials.

A transmitting unit which uses bearings and the eccentric principle to reduce or increase the rotational speed. An eccentric portion is integrally formed with an input shaft, and a bearing is assembled along the outer periphery of the eccentric portion. The bearing is eccentrically moved when the input shaft is rotated. The bearing is surrounded by an integrally formed transmitting race, and plurality of radial holes are formed in the transmitting race. The same plurality of transmitting rods are respectively inserted into the radial holes of the transmitting race. An integrally formed outer race surrounds the outer periphery of the transmitting race, and has a plurality of wave grooves on the inner periphery thereof. The same plurality of balls are respectively provided between the transmitting rods and the wave grooves. According to the transmitting unit, the strength of the unit can increase as the unit can be minimized, while the noise and the vibration of the unit can decrease.
