Welcome to all students in subject design of transmission system. Today we discuss about Corn Clutch. The clutches is a mechanism to transmit rotary motion from one shaft to the another quincident shaft. That is driving shaft to drive one shaft and when required without stopping the driver shaft clutches are also required to disengage the drive from engine to gearbox for the changing the gears. During slowing of vehicle or stopping the clutches used to disengage engine from drive wheels and enable smooth stopping of vehicle. Since clutch is of frictional material it also takes care of speed and torque variation for engine crankshaft to gearbox input shaft. There is some functions of clutch is when clutch is engaged the clutch transmits maximum power from engine crankshaft to gearbox input shaft. When clutch is engaging the clutch accommodates for minor slippages and hence provides smooth drug transmission without jerse. When clutch is disengage when clutch is disengage the clutch allows driver to shift the transmission in various gear positions for second-thirds. When clutch is disengage the engine can be cranks freely without transmitting the driver to the wheel. There is some disadvantages as compared to clutch springs have to be more stiff and this means greater force required to be applied for driver while disengage. This is the diagram of cone clutch. In the diagram there is female cone, male cone, bearings, splines, clutch shaft, spring and friction surface. This is all this is the diagram of cone clutch. In clone clutch this is the diagram. The cones there is female is this is the description of this diagram. Cones is female green male blue shaft male cone is sliding on splines. There is friction material spring brings the male cone back after using the clutch control. Couch control separating both cones by pressing rotating direction both directions of the axis are possible. This is the diagram. These are the shown by 123456. Here we mention 123456. This is the diagram 123456 and after this and here we mention 123456. Now we discuss about cone clutch. In the engage position the friction surface are in complete contact. This is done by means of spring which keep the male cone pressed all the time. When the clutch is engaged the torque is transmitted from engine. Why are the flywheel and the male cone to the spline gear box shaft. For disengaging the clutch the male cone is pulled out by means of lever system operated through clutch pedal thereby separating the contact surface. This is the diagram of cone clutch. All factors are considered dry one shaft and dry one shaft and dry one shaft and friction lining. In friction clutches there are three types plate or disc in friction clutches. There are three types plate or disc clutches blown by cone clutches and centrifugal clutches. In plate clutches there are two types single plate and multiple clutches. Now we discuss about clone clutch. This is the diagram clone clone clutch. In the diagram we given the angle is 5. This is semi apex angle of the cone. This is the friction lining, dry one shaft speed. Now we discuss about the formula. The total frittinal torque is given by T, T is equal to mu W R. R means mean radius. For uniform pressure or for new clutches capital R is equal to 2 by 3 R1 cube minus R2 cube upon R1 square minus R2 square cos E c alpha. For uniform wear for old clutches capital R is equal to R1 plus R2 bracket by 2 cos E c alpha. There is advantages. The advantages of cone clutches is that the normal force acting on contact surface. In this case is larger than axial force as compared to single plate clutches in a which the normal force acting on contact surface is equal to the axial force. Now this advantage is this types of clutch is practically absolute because the following regions. If the angle of cone is less than 20 degree it will be difficult to disengage the clutch. A small amount of wear on the cone surface results in considerable amount of axial moment of the male cone for which it will be difficult to allow. In centrifugal clutch in fully centrifugal type clutches the springs are eliminated along along it together and only centrifugal force is used to apply to apply the required pressure for keeping the clutch is engaged position. This is the diagram. In the diagram there is shown blood spring guide ring and shoe. This is a clutch when stage when clutch flies out. This is low speed this is high speed. Advantages of centrifugal clutches is no separate clutch plate is required clutch is operated automatically depend upon the engaged speed. When design of centrifugal clutch these are the parameters consider any number of shoes M is mass of each shoe capital R is equal to inside radius of the cluck pulley ring small R is equal to distance of entire of gravity of the shoes from the center of the spider capital N is equal to running speed of the pulley omega is equal to angler speed of the pulley 2 pi n upon 16 omega N is equal to angler speed at which the engagement beings to the takes place mu is equal to coefficient of friction between the shoe and ring. Now centrifugal force acting on each shoes Fc is equal to M omega square R spring force exerted by each spring on the shoe F Fs is equal to M omega omega omega omega 1 square R net outward force on the shoe is equal to Fc minus Fs is equal to M omega square R minus M omega omega omega omega 1 square R. Frictional force acting on each shoes F is equal to Mfc minus Fs Frictional torque acting on each shoe TR is equal to F into R that is equal to Mfc minus Fs Frictional torque acting on each shoe is equal to TR is equal to F R that is equal to Mfc minus Fs into capital R. Total frictional torque transmitted capital T is equal to Mfc minus Fs into R and Fr. Size of the shoes is L is equal to contact length of the shoes B is equal to width of the shoes R is equal to contact radius of the shoes theta is equal to angle subtended by the shoes at the center of the spider. B is equal to intensity of pressure exerted on the shoe L one L is equal to R theta sorry I sorry L is equal to R theta area of contact of the shoe is equal to A into L into B net acting on the shoe is equal to Fc minus F A that is equal to A into B that is equal to L into B into B. So today we discuss about what is cone clutch what is the types of cone clutch and how to design the cone clutch. So thank you all of you.
