Bell Crank Assembly

Design of lever involves determination of various dimensions of the lever for a specified load or output force required. For a specified load or output force desired, effort required can be calculated using principle of moments. Due to these forces, arms of the lever are subjected to. A bell-crank lever consists of a long arm, 8 1 2 in. Long, and a short arm 4 in. Long, at right angles to each other. Calculate the force to be applied at right angles to the end of the long arm to overcome a resistance of 40 lbf acting at 30° to the vertical of the short arm. Handlebar lever is rotated at an angle of 90. To push the brake block against the wheel rim 2 Figure 1: Typical example of a bell crank 2 2.0 Initial Load Case. Figure 2: CAD Model of In-line Bell crank thus the results are taken to be as Figure 2 shows the design of the in-line bell crank. The bell crank is expected to be made of steel.

Bell Crank Lever Mechanism

Parametric design charts are proposed for the central-lever steering linkage, generated for simplified reference configuration mechanisms, the geometry of which is defined by only four parameters. This highlights the fact, yet not generally acknowledged, that the steering law ensured by a mechanism with adjacent central joints (known as bell crank mechanism), can be identically generated by a triple central joint variant of the same. Particular configurations are identified in which the length of the central lever does not affect the wheel-to-wheel transmission function of the mechanism, permitting a simplified synthesis for the cases in which the maximum stroke of the input member is imposed as a design specification.
