Abstract: A coupling device for transmitting torque between two rotating drive shaft segments. The coupling device includes a locking mechanism for preventing axial excursions of the drive shaft segments relative to one another when the drive shaft segments are coupled and transmitting torque. The coupling device, furthermore, provides a means for quick disconnect of the drive shaft segments when the transmission of torque is no longer desired and decoupling is preferred. The coupling device, additionally, includes a guide pin and sleeve arrangement for piloting the drive shaft segments during coupling. A drive system is also provided which includes a flexible coupling for accommodating axial and angular misalignment of the drive shaft segments relative to one another.

The winding shaft pin (3) is connected with the drive shaft pin (12) at the end for transmission of the torque.

Abstract: A coolant pump system driven by an electric motor mounted in-line with the pump shaft to the pump housing. The system minimally includes a pump body having a bore therein, a coolant pump impeller, a pump shaft passing through the bore and having the impeller mounted on one end thereof, and a bearingless seal shaft assembly disposed in the bore which prevents coolant from leaking out of the body around the rotating pump shaft. The outer end of the pump shaft and the drive shaft of the electric motor preferably include a quick-disconnect coupler which allows the two shafts to be repeatedly coupled and uncoupled without damage and without tools. This coupling mechanism may take the form of a socket with bayonet slot on one shaft and mating pin on the other shaft that fits in the slot. A face-mounted electric motor is rigidly but removably bolted to the pump housing, and its drive shaft provides complete support for the pump shaft which rotates therewith.

Abstract: A modified jaw type shaft coupling has two opposed members arranged to allow limited flexure about a point that is the geometric center of mating spherical surfaces, a concave surface on one member and a mating convex surface on the other member. One member is attached to each shaft to be rotationally and axially coupled. The jaws on one coupling member have lugs that extend radially inward to axially entrap a larger flange attached to the other coupling member. The flange has notches to allow the flange to axially traverse the lugs. The flange is then rotated relative to the lugs to allow the flange to oppose the lugs. The flange is secured to the other coupling member after the coupling members are axially moved together to allow the jaws to interdigitate to provide rotational coupling. The convex and concave surfaces cooperate to accept axial compressive loads and the flange and lugs prevent axial separation.

The assembly includes a rigid elongated hollow rod member having a body portion and first and second open end portions. Each end portion is adapted to receive either the drive or driven shafts, and is provided with internal involute splines for mating with corresponding external splines on the shafts to be connected by the assembly. The first end portion has an axially displaceable stop member and a biasing spring compressible by displacement of the stop member away from the open first end, for biasing the stop member against the shaft received in the first end portion. The second end portion has a rigid stop at the end of its internal splines, for abutting against the end of the shaft receivable therein.

Abstract: A first shaft which is, for example, the output shaft of a clutch, is coupled to a second shaft which, for example, is the input shaft of a transmission, by a splined coupling. The splined coupling includes a first sleeve having internal splines for splining with the first shaft and external splines for splining with the internal splines of a second sleeve which internal splines also spline with the external splines of the second shaft. A first spring extending between the first sleeve and first shaft biases the first sleeve toward the second shaft, while a second spring extending between the first sleeve and second sleeve biases the second sleeve toward the second shaft. In order to decouple the first shaft from the second shaft so that, for example, a clutch may be removed from a drive train without removing a transmission, the first and second sleeves are pushed to a retracted position, collapsing the first and second springs.

A manually displaceable plunger actuator provides for the manual displacement of the plunger disengaging the roller balls from the inclined surface and permitting the roller balls to move inwardly in a radial direction, and the separation of the inner joint member from the outer joint member.
