FIGURE Epicyclic train dynamometer. direction. The power is transmitted from gear B to D through the intermediate gear C which revolves freely on a pin. This type of dynamometer can be classified as follows: 1. Epicyclic train dynamometer 2. Belt transmission dynamometer 3. Torsion dynamometer. EpicydiC train.

Epicyclic-train Dynamometer-torque and power transmitted ()

Due to this, the light does not reach to the eye piece as shown in Figure c. The pinion revolves freely on a lever. A weight w is placed at the smaller end of the lever in order to keep it in position.

The most general motion is a combination of translation. The energy or power produced by the engine is transmitted through the dynamometer to some other machines where the power developed is suitably measured.

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 trani circumferential adjustment.

The frame is pivoted at E and its movement is controlled by two stops S,S. A counter weight is placed at the other end of the lever which balances the brake when unloaded. The spur gear is keyed to the engine shaft and rotates in anticlockwise direction. The annular gear is also keyed to the driving shaft and rotates in clockwise direction.

Two stops S, S are provided to limit the motion of the lever. A helical spring is provided between the nut and the upper block to adjust the pressure on the pulley to control its speed. The pinion or the intermediate gear meshes with both the spur and annular gears. Since the tension in the tight side of the belt T1 is greater than the tension in the slack side of the belt T2 ,so the total force acting on the pulley C i.

Rotational Dynamics In pure translational motion, all points on an object travel on parallel paths. Share buttons are a little bit lower.

R And power transmitted. A belt dynamometer is introduced to measure directly the dybamometer between the tensions of the belt, while it is running. Nirmal Kushwaha Mechanical Deptt. 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.

In order to prevent the slipping of the rope over the flywheel, wooden blocks are placed at intervals around the circumference of the flywheel. In the transmission dynamometers, the energy is not wasted in friction but is used for doing work. Prony brake dynamometer 2.


Auth with social network: 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. If you wish to download it, please recommend it to your friends in any social system.

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 dyna,ometer opposite to the slot in disc B as shown in Figure d and hence the eye piece receives flash of light. 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. In order to balance it, a weight W is applied at a distance L from E on the frame as shown in Figure.

The upper block synamometer a long lever attached to it and carries a weight W at its outer end. Nirmal Kushwaha”— Presentation transcript:
