It consist of two shafts, two key, flanges, key, pin, rubber bush, brass bush, & pin ,following are the designations of various coupling dimensions which are use for the design procedure.
Explain the design procedure of handlever with neat sketch.
A shaft 1000 mm long is supported between two bearings. A pulley of 250 mm ...........
Write Lewis equation for strength of gear tooth. State the meaning of each term
State any six design considerations while designing the spur gear
1) The power to be transmitted 2) The velocity ration or speed of gear drive. 3) The central distance between the two shafts 4) Input speed of the driving gear. 5) Wear characteristics of the gear tooth for a long satisfactory life. 6) The use of space & material should be economical. 7) Efficiency & speed ratio 8) Cost
State the effect of key-way on the strength of shaft with suitable diagram

Why a coupling should be placed as close to a bearing as possible
Coupling should be placed as close to a bearing because of following reasons i. It gives minimum vibrations ii. Bending load on the shaft can be minimized iii. It increases power transmission stability. iv. To avoid deflections of shaft.
Prove that, for a square key, the permissible crushing stress is twice the permissible shear stress.
A belt pulley is fastened to a 90 mm diameter shaft running at 300 r.p.m. by means of a key 20 mm wide and 140 mm long. Allowable stress for the shaft and key material are 40 N/mm2 in shear and 100 N/mm2 in crushing. Find the power transmitted and the dep
