What is rivet in machine drawing?

A rivet is a simple round rod having head at its one end and the other end is made in the form of head when it is assembled to fasten the parts. Rivet heads are of many shapes. The most common and easiest form of rivet is “snap head rivet”. It is also known as “cup head” or “spherical-head” rivet.

What are the applications of riveted joints?

Applications of riveted joints

• It is used where we have to avoid after thermal effects, as in case of welding.
• Used for metals which have poor weldability.
• Used for heterogeneous materials like asbestos friction lining and steel.

What is riveted joint design?

Riveted joints are formed between each of the plates and one or two cover plates. Depending upon the number of cover plates the butt joints may be single strap or double strap butt joints. Like lap joints, the arrangement of the rivets may be of various kinds, namely, single row, double or triple chain or zigzag.

Where are riveted joints used in industry?

Below are the applications of rivet joints: Rivet joints are permanent joints used mainly for fastening sheets and shaped rolled metal. They are used in lap, abutment, and double-cover plate joints. They can still be used for constructing a metal bridge, hoisting cranes, boilers, and pressure tanks.

What is a riveted joint in Mechanical Engineering?

The document Chapter 6 – Riveted Joints – Machine Design, Mechanical Engineering Mechanical Engineering Notes | EduRev is a part of the Mechanical Engineering Course Mechanical Engineering SSC JE (Technical) . A rivet is a short cylindrical bar with or head integral to it.

How are rivets used in a lap joint?

In a lap joint the edges of plates are simply laid over each other and riveted. Figures (a) and (d) show lap joints. If we pull the plates by application of tensile forces, they do not fall in the same line and hence cause the rivets and plates to bend. Plates placed end-to-end and jointed through cover plates form single cover butt joint.

When do you use multiple rows of rivets?

Single or multiple rows of rivets are used to give strength to the joint. Depending upon the number of rows the riveted joints may be classified as single riveted lap joint, double or triple riveted lap joint etc. When multiple joints are used, the arrangement of rivets between two neighbouring rows may be of two kinds.

How are rivets arranged in a double cover butt joint?

A double riveted double cover butt joint is shown in Figure (f). The arrangement of rivets in Figure (d) can be described that in both the rows the rivets are opposite to each other while in Figure (e) the rivets in the adjacent rows are staggered. The joint in Figure (d) is said to be chain riveted while that in
