My presentations Profile Feedback Log out. Registration Forgot your password? Auth with social network: The pinion revolves freely on a lever. 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. A little consideration will show that when the power is elicyclic transmitted, then the driving end of the shaft twists through a small angle relative to the driven end of the shaft.

Rotational Dynamics In pure translational motion, all points on an object travel on parallel paths. 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 xynamometer.

If you wish to download it, please recommend it to your friends in any social system. We think dynamomrter have liked this presentation. The spur gear is keyed to the engine shaft and rotates in anticlockwise direction. Prony brake epicyclkc 2. Since the tension in the tight side of the belt T1 is greater than the tension in trani slack side of the belt T2 ,so the total force acting on the pulley C i.


It consists of one, two or more ropes wound around the flywheel or rim of a pulley fixed rigidly to the shaft of an engine. A helical spring is provided between the nut and the upper block to adjust the pressure on the pulley to control its speed.

Epicyclic-train Dynamometer-torque and power transmitted ()

Engineering College Palanpur Name: The pulleys A and B are connected by epiccyclic of a continuous belt passing round the two loose pulleys C and D which are mounted on a T-shaped frame. The energy or power produced by the engine is transmitted through the dynamometer to some other machines where the power developed is suitably measured.

A weight w is placed at the smaller end of the lever in order to keep it in position. Published by Dynqmometer Daniel Modified over 2 years ago. There is another pulley B called driven pulley mounted on another shaft to which the power from pulley A is transmitted.

Belt transmission dynamometer 3. Feedback Privacy Policy Feedback. The tangential effort Dynamomwter exerted by the spur gear on the pinion and the tangential reaction of the annular gear on the pinion are equal. The upper block has a long lever attached to it and carries a weight W at its outer end. For a solid shaft of diameter D, grain polar moment of inertia for a hollow shaft of external diameter D and internal diameter d, the polar moment of inertia, From the above torsion equation the power transmitted.

In order to balance it, a weight W is applied at a distance L from E on dynamometsr frame as shown in Figure. Nirmal Kushwaha”— Presentation transcript: It consists of two discs A and B fixed on a shaft at a convenient distance apart Each disc has a small radial slot and these two slots are in the same line when no power is transmitted and there is no torque on the ttain. The frame is pivoted at E and its movement is controlled by two stops S,S. To make this website work, we log user data and share it with processors.


Share buttons are a little bit lower. 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 measurement.

Due to this, the light does not reach to the eye piece dynamomete shown in Figure c. In the transmission dynamometers, the energy is not wasted in friction but is used for doing work. About project SlidePlayer Terms of Service. It consists of a pulley A called driving pulley which is rigidly fixed tothe shaft of an engine whose power is required to be measured.

The upper end epicyclci the ropes is attached to a spring balance while the lower epixyclic of the ropes is kept in position by applying a dead weight as shown in Figure.

A belt dynamometer is introduced to measure directly the difference between the tensions of the belt, while it is running. Absorption dynamometers, and 2.

It is thus obvious that the frame causes movement about E in the anticlockwise direction. 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. The pinion or the intermediate gear meshes with both the spur and annular gears.
