Step 2: An assembly drawing shows a structure or product's connected components in their respective working locations during use. These parts are manufactured individually, then put together or installed at their utility locations so that each part is compatible with the others.
Some sleeve couplings and shafts have threaded holes that match up on assembly to prevent any axial movement of the shafts. The power transmission from one shaft to the other occurs through the sleeve, the keyway and the key. This shaft coupling is used for light to medium-duty torques.
For easier assembly, the sleeve in a sleeve coupling can be divided into two parts. By doing this, the technician no longer needs to move the connected shafts for assembly or disassembly of a coupling.
The universal joint consists of a pair of hinges connected through a cross-shaft. The two hinges are positioned at 90 degrees to each other. The cross-shaft maintains this orientation and is also responsible for the power transfer. The universal joint is not a constant velocity coupling, i.e., the driving and driven shafts rotate at different speeds.
Shaft couplings are an integral component of motion control and power transmission systems. They provide incredible advantages and combat many assembly and service environment issues when applied correctly.
In an aspect, a universal conduit body assembly comprises a universal conduit body having a first port attached thereto. The first port is sized and shaped to connect the conduit body with one or more conduits or plugs. A cavity is at least partially defined by the conduit body, and the cavity comprises at least two open sides and sufficient space for containment of one or more spliced wires within the conduit body. Two or more removable panels each sized and shaped to cover a portion of the universal conduit body and selectively attach to each of the at least two open sides of the cavity are provided. At least one of the two or more panels includes a second port sized and shaped to connect the panel with the one or more conduits or plugs.
1. The patent relates to a bearing for coupling two carriages of, for instance, a tram or light rail vehicle and accommodating universal articulation between the carriages. Spherical bearing surfaces are provided between an annular, outer bearing member connectable to one carriage and an assembly of an inner bearing member and outer housing connectable to the other carriage. The inner bearing member is mounted on a central post which is integral with the outer housing, has a frusto-conical form and forms an end stop with the outer bearing member. The only matter at issue is inventive step.
2.2 D1 relates to the accommodation of higher loads in spherical joints between heavy rail vehicles by providing an intermediate, replaceable layer between the spherical surfaces in the outer housing and the outer ball. In the embodiment the intermediate layer is provided in an assembly which is generally not described and is disclosed essentially only in the drawing figure 1. From figure 1 an assembly is apparent in which the spherical surface of the outer housing comprises a central inward axial projection, the inner ball sits against the end surface of the projection and is retained by the head of a bolt passing through a hole in the projection and secured by a nut on the outside of the outer housing. The projection is apparently essentially cylindrical and the central aperture of the outer bearing comprises a chamfered surface.
3. The appellant alternatively argued that D1 may form the closest state of the art for consideration of inventive step, whereby the problem would be to permit assembly of the coupling with access from only one side. However, as has already been set out above, a combination of D1 and D4 would not result in all features of present claim 1 so that a detailed analysis of this line of argumentation is not necessary.
