compression coil spring

An automatic production machine requires a compression coil spring to keep a follower in contact with a cam that rotates at speeds up to 1800 rpm. When installed, the spring force is to vary between 150 and 600 N while the spring height varies over a range of 10 mm. An available supply of 4.5-mm-diameter shot-peened wire is to be used, for which Figure 12.16 applies. Clash allowance is to be 2.5 mm. The design is to be tentatively based on limiting the stress to 800 MPa when the spring is closed solid. Ends are to be squared and ground, and presetting will not be used.

 

(a) Determine appropriate values for D, N, Ls, and Lf.

(b) Determine the likelihood of the spring’s buckling, the likelihood of encountering spring surge problems, and the approximate safety factor during normal operation.

(c) What would the approximate safety factor of the spring be (with respect to fatigue failure) if presetting is used, resulting in a residual torsional stress of 100 MPa?
