Abstract: Apparatus (300) is disclosed for locking a key (322) in a keyway (302) of a shaft (10) and of a hub slideably receiving the shaft (10). The key (322) is tapered and includes a top extending at an acute angle to the bottom, with the keyway (302) of the shaft (10) having a bottom wall (306) at the acute angle to the axis of the shaft (10). A push rod (312) is rotatable in an axial bore (308) in the shaft (10) and includes a threaded portion (318) threaded into a threaded counterbore (310) of the axial bore (308). The forward end of the push rod (312) is interconnected to the key (322) by a lip (336) formed in the key (322) extending into a notch (316) formed in the push rod (312). Rotation of the push rod (312) causes the push rod (312) to move axially in the axial bore (308) which in turn axially moves the key (322) in the keyway (302).

Abstract: A pressurized fluid actuated multi-disk clutch for vehicles, in particular a clutch provided for the shifting of an additional axle in the drive line of an agricultural or industrial vehicle is described. The multi-disk clutch contains a clutch bell housing (34) within which outer clutch disks (30) are arranged, fixed against rotation, and which is supported in bearing, free to rotate, on a shaft (12) with a set of gear teeth that mesh with inner clutch disks (26). Furthermore a piston (46) is provided that can be moved axially against the force of a spring arrangement (54, 55) by means of a pressurized fluid and that acts upon the clutch disk package (28) consisting of the inner clutch disks (26) and the outer clutch disks (30).

Abstract: An improved elongate key (92) is provided for securing thrust washers to a mainshaft (48) of a transmission (100). Key (92) has a substantially triangular cross-sectional configuration having rounded intersections between adjacent surfaces rendering it easily insertable axially through keyways defined between external axially extending grooves (66) in mainshaft (48) and aligned internal grooves (86) in the thrust washer which itself is preferably provided with rounded corners (90) to enhance the strength thereof.

Abstract: A press has a flywheel and a spindle both rotatable about an axis, an axially displaceable ram and nut threadedly engaging the spindle so that rotation of the spindle axially displaces the ram, and a clutch between the flywheel and the spindle. The clutch has a housing formed with a radially open service port, a clutch plate rotationally fixed to the flywheel, and another clutch plate rotationally fixed to the spindle. One of the plates is formed with axially open cavities and one of the plates is axially movable through a relatively long stroke between an outer position with the plates spaced apart and an inner position with the plates close together. High-friction coupling elements of a predetermined axial height shorter by a working distance than the long plate stroke are seated in the cavities. The movable clutch plate can be displaced through the long axial stroke so that the clutch plates engage axially and rotationally link the spindle and flywheel.

Abstract: A drive for a circular knitting machine (10) used in the manufacture of panty hose blanks, using a one-way clutch (A) in the drive connection which permits a main drive shaft (16) to be rotated in one direction but does not permit it to be rotated in the opposite direction. The knitting machine may also be driven while the main power source is at rest, that is, the knitting machine may over-run or coast to a stop after the power source has been disconnected and the needle cylinder may be revolved manually during set up. The one-way clutch (A) comprises a clutch body (30) which is connected to the main drive shaft (16) and fits within an outer race (28) of an input drive sheave (20) which is driven by a suitable power source.

Abstract: A very low spring rate vibration-damping clutch and pinion assembly for lowering the resonance of a power train to below the resonant speed of the engine includes a vibration damping clutch with two circumferential rows of springs and a necked-down pinion shaft. The vibration damper is preferably connected to both the pinion shaft and the clutch disk by spline connections.

Abstract: An energy converter transmission uses a throughshaft clutch and a through-shaft energy converter for transfer of energy to and from a shaft. The energy converter includes a housing and a rotor mounted to a hollow coupling shaft. The energy converter can be an hydraulic, a pneumatic or an electric energy converter. A first clutch element is also mounted to the coupling shaft. A second clutch element is mounted to the main drive shaft which passes through the hollow coupling shaft. Actuation of the clutch engages the clutch elements to couple the main drive shaft to the rotor via the clutch and coupling shaft.

Abstract: A drive unit comprises a motor with a motor casing, a gear box with a gear box casing, and a pulled-type clutch for torque transmission between the motor and the gear box. The gear box casing is to be fixed to the motor casing. The clutch comprises a clutch release system for transmitting a clutch release force from an actuating pedal to a diaphragm spring of the clutch. In this clutch release system there is provided a snap connection which is closed by approaching the motor casing and the gear box casing towards the relative operative position.

Abstract: A clutch housing for the transmission of an automotive vehicle has an integral front cover, and a release bearing sleeve formed separately from and detachably secured to the front cover in communication with a stepped hole extending therethrough. An input shaft extends through both the stepped hole and the release bearing sleeve. The input shaft is rotatably supported by a bearing located in the stepped hole. An oil seal surrounds the input shaft and is retained within the release bearing sleeve at a location spaced axially from the bearing.

Abstract: A free floating coupling device for use between drive and driven shafts, which coupling device consists of a clutch portion on each shaft, which clutch portions are held in spaced apart relation by a tubular member which serves as a bearing lubricant chamber. The coupling allows power to be transmitted from the drive shaft to the driven shaft, even when a slight mis-alignment exists between the shafts. The anti-friction bearings allow full torque to be exerted between the shafts.
