STUDY OF DRUM BRAKE

What is drum brake? A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum. The term drum brake usually means a brake in which shoes press on the inner surface of the drum. When shoes press on the outside of the drum, it is usually called a clasp brake. Where the drum is pinched between two shoes, similar to a conventional disc brake, it is sometimes called a pinch drum brake, though such brakes are relatively rare. A related type called a band brake uses a flexible belt or "band" wrapping around the outside of a drum. Components:- 1. Backing plate 2. Brake drum 3. Wheel cylinder 4. Brake shoes. Backing plate The backing plate provides a base for the other components. The back plate also increases the rigidity of whole set-up, supports the housing, and protects it from foreign materials like dust and other road debris. It absorbs the torque from the braking action, and that is ...

KAIZEN IMPLEMENTATION IN AN INDUSTRY (case study)

INTRODUCTION   Improving customer service, making operation faster, more operation and reduction in costs are challenges faced by manufacturers today. To meet these challenges many companies in India searching to improve their ability to compete globaly. Wastage during production process is rapidly growing day by day in industries. This is because of change in taste of the customer. Which will lead to increase in production costs. There are different techniques of waste reduction and performance enhancement like Just In Time (JIT), Total Quality Management (TQM), Total Productive Maintenance (TPM), Kaizen etc.          Kaizen is a Japanese hybrid work. It is a compound word involving two concepts: Kai (change) and Zen (for the better). The term comes from Gemba Kaizen meaning ‘Continuous Improvement’ (CI). Continuous Improvement is one of the core strategies for excellence in production, and is considered vital in today’s competitive environment. It ca...

Types of joint (knuckle joint ,cotter joints and turnbuckle joint)

INTRODUCTION OF KNUCKLE JOINT: . A knuckle joint is a mechanical joint used to connect two rods which are under a tensile load, when there is a requirement of small amount of flexibility, or angular moment is necessary. There is always axial or linear line of action of load.  The knuckle joint assembly consists of the following major components: Single eye. Double eye or fork Knuckle pin. Collar Taper pin At one end of the rod the a single eye is formed and a double eye is formed at the other end of the rod. Both, single and double eye are connected by a pin inserted through the eye. The pin has a head at one end and at other end there is a taper pin or split pin. For gripping purpose, the ends of the rod are of octagonal forms. Now, when the two eyes are pulled apart, the pin holds them together. The solid rod portion of the joint in this case is much stronger than the portion through which the pin passes.  The modes of failure are: Shear failure of pin (single shear). Crushi...
