How do you select a shaft for small sprocket in your chain drive?
Step by step
Solved in 2 steps
- 7. A typical drive train for a 'geared' bicycle meant to be used on paved road (see a representative image) has 48 teeth on front sprocket (Crank side), the diameter of front sprocket being 10.5 inches. The rear wheel has a cassette with a cluster of 6 sprockets, with number of teeth on Sprocket #1 (lowest gear) to Sprocket # 6 (highest gear) being 30, 26, 23, 20, 16 and 12, respectively. (Ignore wind resistance and friction between machine elements) (a) If the rider is pedaling at a constant 105 rpm with an effective force of 28 lb acting on periphery of front Sprocket (at 5.25 inch radius length, the force location indicated by red arrow), and is engaged in Sprocket #5, what would be the torque acting on Sprocket # 5, and the RPM at which the rear wheel is spinning? (b) For the condition as described in (a), If the diameter of wheels is 26 inches, what is the speed of the bicycle? &Q- The reduction of speed from 360 rpm to 120 rpm is desired by the use of a chain drive. The driving sprocket has 18 teeth. What is the number of teeth on the driven sprocket?Problem Chain and Sprocket. A single-strand roller chain drive connects a 10-hp engine to a lawn waste chipper/shredder. As the engine operates at 1200 rpm, the shredding teeth should rotate at 240 rpm. The drive sprocket has 18 teeth. Determine an appropriate pitch for the chain, the number of teeth on the driven sprocket, the pitch diameters of both sprockets, and the chain speed. Also indicate the number of links in a suitable chain and specify the required center distance.
- An AC motor operating at 870 rpm drives a sheave for a 5V belt with a diameter of 8.9 inches. The desired output shaft speed is 560 rpm. a. For the output shaft, is the 13.1 inch sheave, or the 13.9 inch sheave, a better choice?A. PROBLEM ON TOPIC "KEYS AND COUPLINGS": A coupling with material AISI C1045 as rolled transmits 65.5 HP at 1750 rpm. The material of the 1.75 inch shaft... is also AISI C1045 as rolled and the key is cold drawn AISI C1020. N= 2.5. Determine the following: 1. Size of bolt (dia.) if there are 6 bolts made of AISI C1045 as rolled at a bolt circle of 5 inches. Note: Select standard bolt diameter from AT14 of DOME by Faires (see Lecture on fasteners for this Table) Calculated Dia: Standard Size to use: 2. Required b and t if a flat or rectangular key is used: Answer: 3. Required length of key, if a flat or rectangular key is used: Note: Calculate for two type of stresses on key, then select your answer. Length Based on shear length Based on compression: Length to use: 4. Required bif a square key is used: Answer: 5. Required length of key, if a square key is used: Note: Calculate for two type of stresses on kev, then select your answer. Length Based on shear length Based on compression:…What will be the centre distance of two meshing gears il module is 4 and no ofteeths are 25 and 75?
- A bearing (babbitted) with a 1 3/4 inch bore is fitted to the new shaft of a motor by reaming. If the reaming process increases the diameter of the bore by 0.003 inch, what is the size of the bore after the work is completed?The advantage of herringbone gear compared to a helical gear is the internal cancellation of its axial thrust loads Select one: True FalseThe questions is this: A 5000-lb. gear box is provided with a steel (as rolled B1113) eyebolt for use in moving it. What size bolt should be used: a.if UNC threads are used? b.If UNF threads are used? c.If the 8-thread series is used? and I got the answer in the picture provided. Can you explain further the basis of the choice of the design factor?
