A multiflex flexible coupling, transmitting 15 kW power at 720 rpm, is shown in Fig. 9.46. It consists of two flanges keyed to the driving and driven shafts and connected together by means of a mumber of coils. The coils are placed in the slots on the periphery of the flanges at a distance of 30 mm from the axes of the shafts. The coils have a rectangular cross-section 4 x 2 mm and are made of steel FeE 220 (S, = 220 N/mm²). The factor of safety is 2.5. Calculate the required number of coils.

I want right solution plz solve if you know 100% flange coupling connects two 50 mm diameter lengths of commercial shafting. The coupling flanges are bolted together with four bolts of the same material as the shaft. The bolts are set in clearance holes. The diameter of the bolt circle is 240 mm and the flange thickness is 22 mm, Determine the minimum bolt diameter required to transmit the same torque that the shaft can transmit. What power may be transmitted at 200 rev/ min under steady load conditions?

A 55-hp four-cylinder internal combustion engine is used to drive a medium-shock brick-making machine under a schedule of two shifts per day. The drive consists of two 25-in sheaves, with a sheave speed of 425 rev/min. A value of Ks = 1.5 and a design factor of 1.0 applies. Determine the number of D360 V-belts needed, calculate the factor of safety, and estimate the life in hours. The number of D360 V-belts needed is The factor of safety, nfs, is belts. and the life of the belts is hours.

A narrow V-belt (wedge belt) transmits power from an internal combustion engine operating at 700 rpm to the shaft of a dough mixer (medium duty) operating at 50 rpm. The internal combustion engine develops a nominal power of 50 kW and the dough mixer operates for no more than 8 hours per day. Which of the following belts can be used for this application? Hint: First determine the design load by using an appropriate service factor from page F12 in Appendix H in the Design Manual. SPC only SPB or SPC SPA or SPB SPB only
A chain drive is desired to couple a gearmotor with a bucket elevator. The 40 hp. gearmotor will operate at 350 rpm and the elevator drive shaft must operate as close to 60 rpm as possible. Select an appropriate chain size, commercially available sprockets, and number of links for a chain. Also calculate the actual chain speed and the center distance.
