2. A blower is driven by an electric motor though a belt drive. The motor runs at 750 r.p.m. For this power transmission, a flat belt of 8 mm thickness and 250 mm width is used. The diameter of the motor pulley is 350 mm and that of the blower pulley 1350 mm. The center distance between these pulleys is 1350 mm and an open belt configuration is adopted. The pulleys are made out of cast iron. The frictional coefficient between the belt and pulley is 0.35 and the permissible stress for the belt material can be taken as 2.5 N/mm2 with sufficient factor of safety. The mass of a belt is 2 kg per meter length. Find the maximum power transmitted without belt slipping in any one of the pulleys. [Ans. 35.9 kW]
An Electrical motor (heavy start) that delivers 53,57 kW at 1440 r/min must be connected to a rotary compressor with a wedge belt drive. The compressor must operate 24 hours per day with a shaft speed of approximately 966 r/min. The center distance must be closest to 1000 mm.
The BAPCO in Bahrain is looking to design a V belt drive system for its recently installed rotary machines. The smaller pulley having a diameter of * d" is connected to an electric motor and run at a speed of nd. The belt is used to drive a larger pulley at a speed of 90 rpm. The V belt is used to transmits a power of 95 hp and ignore it in belt class selection process (Table 17.9). The service factor for the V belt drive system is 1.3 and the suggested factor of safety for the current design is 2.5. Smaller Pulley Diameter = d = 9 in Speed of smaller pulley = nd = 900 rpm Design and select a V belt drive system.
For the belt drive shown below calculate the contact angle 0, if: D = 100 mm; d = 30 mm; C = 300 mm.

Q. No 1. Derive the expressions for A, B, & C in the given figure with the help of clear drawing and stepwise procedure. Also find the expression for the Length of the belt drives for open and closed belt drives. B=?. sin D+d 2C A=? sin D+d 2C VAC - (D+ dỷ
A V-Belt drive is designed so that it has the input sheave on the shaft of an electric motor (normal torque) rated at .55 hp at 1160 rpm full-load speed. The drive is to a bucket elevator that is to be used 12 hours daily at approximately 675 rpm. The center distance is about 19.5 in. Add the detailed steps of your design to your attached worksheet. Hints: 1) In your design choose an appropriate belt section, specify the small pulley diameter, the large pulley diameter and the length of the belt. Determine the Belt length in inches, in two significant figures. Please enter below a numerical value only, no units are needed. Answer:
A pump is driven by an electric motor through a open type flat belt drive.Motor pulley diameter (DS) = 300 mm, Pump pulley diameter (DL) = 600 mm. The Center distance between the pulleys=1000 mm. Find the length of the belt in inches
