Gardagis R And power transmitted. The pinion revolves freely on a lever. The upper end of the ropes is attached to a spring balance while the lower end of the ropes is kept in position by applying a dead weight as shown in Figure. V-belt drive V-belt is mostly used in factories and workshops where a great amount of power is to be transmitted from one pulley to another when epocyclic two.

Voodoobei A helical spring is provided between the nut and the upper block to adjust the pressure on the pulley to control its speed. We think you have liked this presentation. In order to balance it, a weight W is applied at a distance L from E on the frame as shown in Figure. The most general motion is a combination of translation.

At every revolution of the shaft, a flash of light is projected through the slot in the disc A An eye piece E is fitted behind the disc B on the shaft bearing and is capable of slight circumferential adjustment. Engineering College Palanpur Name: Rotational Dynamics In pure translational motion, all points on an object travel on parallel epicycpic. Auth with social network: The upper end of the ropes is attached to a spring balance while the lower end of the ropes is kept in position by applying a dead weight as shown in Figure.
It consists of one, two or more traiin wound around the flywheel or rim of a pulley fixed rigidly to the shaft of an engine. Belt transmission dynamometer 3. V-belt drive V-belt is mostly used in factories and workshops where a great amount of power is to be transmitted from one pulley to another when the two.
R And power transmitted. In the absorption dynamometers, the entire energy or power produced by the engine is absorbed by the friction resistances of the brake and is transformed into heat, during the process of spicyclic. A counter weight is placed at the other end of the lever which balances the brake when unloaded. Registration Forgot your password? The tangential effort P exerted by the spur gear on the pinion and the tangential reaction of the annular gear on the pinion are equal.
There is another pulley B called driven pulley mounted on another shaft to which the power from pulley Dynamomeer is transmitted. The spur gear is keyed to the engine shaft and rotates in anticlockwise direction. If the eye piece is now moved round by an amount equal to the lag of disc B, then the slot in the eye piece will be opposite to the slot in disc B as shown in Figure d and hence the eye piece receives flash of light.
Due to this, the light does not reach to the eye piece as shown in Figure c. A bright electric lamp L, behind the disc A, is fixed on the bearing of the shaft. The upper block has a long lever attached to it and carries a weight W at its outer end.
It consists of two discs A and B fixed on a shaft at a convenient distance apart Each disc has a small radial slot epicyclid these two slots are in the same line when no power is transmitted and there is no torque on the shaft. The pinion revolves freely on a lever. In order to prevent the slipping of the rope over the flywheel, wooden blocks are placed at intervals around the circumference of the flywheel.
Epicyclic-train Dynamometer-torque and power transmitted The energy or power produced by the engine is transmitted through the dynamometer to some other machines where the power developed is suitably measured.
The annular gear is also keyed to the driving shaft and rotates in clockwise direction. Prony brake dynamometer 2. The amount of twist depends upon many factors such as torque acting on the shaft T length of the shaft l diameter of the shaft D modulus of rigidity C of the material of the shaft.
Compound planetary gears[ edit ] Stepped planet series of the Rohloff Speedhub internally geared bicycle hub with the smaller planet series meshing with the sun wheel and the larger planet series meshing with the ring gear. Some designs use "stepped-planet" which have two differently-sized gears on either end of a common shaft. The small end engages the sun, while the large end engages the ring gear. This may be necessary to achieve smaller step changes in gear ratio when the overall package size is limited. Compound planets have "timing marks" or "relative gear mesh phase" in technical term. The assembly conditions of compound planetary gears are more restrictive than simple planetary gears,  and they must be assembled in the correct initial orientation relative to each other, or their teeth will not simultaneously engage the sun and ring gear at opposite ends of the planet, leading to very rough running and short life. Compound planetary gears can easily achieve larger transmission ratio with equal or smaller volume.

Due to this, the light does not reach to the eye piece as shown in Figure c. Auth with social network: Share buttons are a little bit lower.
