Balancing of Rotating Masses
BALANCING INTRODUCTION: Balancing is the process of eliminating or at least reducing the ground forces and/or moments. It is achieved by changing the location of the mass centres of links.…
PARTIAL BALANCING OF LOCOMOTIVES
Variation of Tractive force: The resultant unbalanced force due to the cylinders, along the line of stroke, is known as tractive force. Swaying Couple: The couple has swaying effect about…
BALANCING OF SINGLE CYLINDER ENGINE
A single cylinder engine produces three main vibrations. In describing them we will assume that the cylinder is vertical. Firstly, in an engine with no balancing counterweights, there would be…
Static And Dynamic Balancing
Definitions Primary Balancing describes the process where primary forces caused by unbalanced mass components in a rotating object may be re solved into one plane and balanced by adding a…
BELT
The belt or ropes are used to transmit power from one shaft to another shaft by means of pulleys which rotate at the same speed or at different speed. Types…
Types of friction
1. Static friction: It is experienced by a body, when at rest. 2. Dynamic friction: It is friction experienced by a body when in motion. a. Sliding friction: It is friction experienced by…
Epicyclic gear trains
1. If the axis of the shafts over which the gears are mounted are moving relative to a fixed axis , the gear train is called the epicyclic gear train. 2. Problems…
Parallel axis gear trains
· Simple Gear Trains – A simple gear train is a collection of meshing gears where each gear is on its own axis. The train ratio for a simple gear train is the…
Gears And Trains
Introduction: The slip and creep in the belt or rope drives is a common phenomenon, in the transmission of motion or power between two shafts. The effect of slip is to…
