SERVICE REQUIRED:

1.Necessary surface grinding machine. 2.230 volts, single phase, 50 Hz stabilized power supply.

The apparatus is designed to study the cam profiles and performance of cam and follower system. The apparatus consists of a shaft supported by ball bearings upon which three different types of cams can be mounted. The push rod for follower is supported vertically, which can adopt three different types of followers. Cams and followers can be changed easily. A variable speed motor rotates the cam. A dial gauge permits plotting of follower displacement with respect to cam position. By operating the system at different Speeds, jump speed can be found and also the effect of weight and spring force on jump speed can be studied. Jump can be visualized also with the help of stroboscope (it is not supplied With the product).

SPECIFICATIONS OF CAM ANALYSIS APPARATUS:

1.Cam -Eccentric, tangent and circular ARC type – one each. 2.Follower- mushroom, flat faced and roller type – one each. 3.Cams and followers are hardened to reduce wear of the surfaces. 4.Variable speed motor coupled to camshaft of suitable range and Variac. 5.A dial gauge to note the follower displacement. 6.A technical manual accompanies the equipment.

SERVICES REQUIRE FOR CAM ANALYSIS APPARATUS:

1.230 V, A.C. stabilized supply along with earthing connection. 2.Bench area 0.5m x 0.5m x 0.5m height. 3.Tachometer to measure the jumping speed, (can be supplied extra)

The VIBLAB is designed to help in conducting various experiments to illustrate and verify the principles and relations involved in the study of vibrations. This apparatus enables a comprehensive range of Vibration Experiments to be conducted on single basic framework. The frame is robustly constructed from channel section. The experiments are specially designed for quick and easy assembly on to the framework using a minimum amount of common engineering tools. To reduce changeover time on tube more advanced free and forced vibration experiments, large knurled knobs are used to clamp components on the frame and many components are common to several experiments. All of the referenced groups of experiments are available separately making it possible to procure them individually & if required to build up a complete set over a period of time.

Specifications:

1.Wide range of experiments. 2.Forced and Free Vibrations. 3.Damped and undamped vibrations. 4.Arrangements for variation of damping. 5.Sturdy storage cabinet. 6.Experiments easily assembled. 7.Covers experiments for undergraduate studies. 8.Scope for student projects.
