Tool Dynamometers

This is a armed wheel type strain gauge drill tool dynamometer designed to measure thrust and torque during drilling operation. This Dynamometer is suitable for drilling a hole up to 25mm size in mild steel. With this Dynamometer students can study the change in these force by varying speed, cut and feed

FEATURES:

1.Rigid in construction & Sensitive transuding and amplifying system for accuracy in force measurement. 2.Compact two channel digital force indicator. 3.Use of cutting fluid during operation is possible

SCOPE OF SUPPLY:

1.Mechanical sensing unit and work piece holder with strain gauges. 2.Control panel housing digital force indicator to measure both forces simultaneously, balancing potentiometer, connoting cables. 3.Necessary switches, fuses and screen printed front plate. 4.The dynamometer is calibrated at factory with help of proving ring and readings are directly in the from of kg.

This board illustrates the process of cutting of involutes Gear Teeth, by use of rack type cutter It consists of 3 white acrylic discs A, B, C. having pitch circle diameter 450 mm, 300 mm & 200 mm respectively. A gear tooth profile with module 25mm can be traced out on a peace of paper placed between disc and cutter. An affect of Interference and Undercutting on correct profile of gear tooth can be studied from the profiles traced.

The unit consists of a main spindle driven by a variable speed motor. Three different governor assemblies can be mounted over the spindle. A with pointer measures the lift of the governor. Students can calculate characteristics of governor at and compare their performance viz. Sensitiveness, stability, governor effort etc.

SPECIFICATIONS OF WHIRLING OF SHAFT APPARATUS:

1.Governor assemblies – Hartnell, porter & propel governor assembly one each with rotating weights. 2.Variable speed FHP D.C. motor to drive the main spindle. 3.Sliding weights for porter & proell governor. 4.Scale & a pointer to measure governor lift. 5.Spring & Spring compression adjustment arrangement. 6.A technical manual accompanies the unit.

SERVICES REQUIRE FOR WHIRLING OF SHAFT APPARATUS:

1.230V, 5A, AC supply connection. 2.Bench area of 0. 75 x 1m. at working height.

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.
