ball rod end joints, of a type well known in the art, to allow for load transmitting and a wide range of motion between the upper body and hips of the wearer. Links 617 may be a shock absorbing link or sculpted washers may be used with links 617 so as to at least partially absorb...
FIG. 4 is a side elevational view of the pivoting connecting joint of FIG. 3. FIG. 5 is a rear elevational view of one embodiment of a typical pack frame constructed according to the present invention shown mounted on the back of a person stepping forward with his right foot. ...
Bolted ball-cylinder (BBC) joints are suitable for non-purlin space structures to effectively reduce structure height and save material costs. In this paper, we present a numerical and theoretical study for high-strength steel BBC joints at elevated temperatures. An finite element (FE) model was...
Additional fasteners can be omitted among the assemblies, thus preventing the weakening of joint strength [2]. An interference fit also has good aligning performance and large load-carrying capacity under complex operating conditions. The torque, axial force, or the combination of both can be ...
The wheels may be pivoted by means of a ball joint (figure 5), and the connection between the two vehicles may be strengthened by means of vertical frame members also being secured together (figure 3).LINDA * SEARCINDY * CROOT
The trailer is connected by a universal or ball joint 18 with a connector 20 comprising bars 21, 22, Fig. 2, and pivoted holding bars 23, 24 which may take the form of bars 26 which are clamped to the rear braces 29 of the cycle. The device may be turned up to either of the ...
A number of shafts of C40 steel of nominal diameter 20mm were manufactured with varying cylindricity values and selectively assembled with standard deep grove ball bearings, thereby achieving interference fits with a grade of H7/u6 between them. The assembled specimens were tested on a Universal ...
