Whitworth Quick Return Apparatus | ProDynami 1244
Whitworth Quick Return Apparatus ProDynami 1244 produces and analyzes irregular reciprocating motion with slow feed and quick return. This Whitworth Quick Return Apparatus features a driving crank and driven slider crank, with a crank radius of 46mm, slider radius of 55mm, and connecting rod length of 145mm. The input angle is set by turning the crank, and the output stroke is read on a ruler on the slider. Transmission components are made of aluminium, mounted on ball bearings, and the unit is easy to carry using two handles.
The Whitworth Quick Return Apparatus ProDynami 1244 is a benchtop model used to produce and analyze irregular reciprocating motion with slow feed and quick return. This Whitworth Quick Return Apparatus clearly demonstrates the transmission pattern of such an assembly, with the input angle set by turning the crank and the output stroke read on a ruler on the slider.
Product Overview
The Whitworth Quick Return Apparatus ProDynami 1244 consists of two cranks: a driving crank and a driven slider crank, a ruler, and a rotating disc on which the driven crank is attached. It is used to generate uneven reciprocating motion with slow feed and quick return. The input angle is set by turning the crank. The output stroke is read on a ruler on the slider. The transmission components are manufactured in aluminium. All axles are equipped with ball bearings. Due to its low weight, this Whitworth Quick Return Apparatus is easy to carry using the two handles.
