Worm gears are widely used in industrial settings and in automobile gear boxes. This worm gear design tutorial will discuss the basics of the worm gear box design calculation using the AGMA empirical formula. A worm gear box must contain a worm and a mating gear (helical gear) and normally the axis of the worm is perpendicular…
Humans are seen by the Biomechatronics science as a set of systems all related and working together. Learn about the Human Motor Control System, Affected Human Motor Control, and Assistive Motor Control Systems. This is the second article of the series of a new exciting field known as Biomechatronic The whole field of Biomechatronics is…
Named after its Inventor Dr. James Bibby in 1917, this coupling is still one of the most sought after flexible couplings for heavy shock applications. Let us now look at the constructional features of the coupling. 1. The Coupling consists of two flanges or hubs specifically mounted on the drive and the driven shafts respectively. These…
Couplings are used as connecting elements between two shafts. The complexity in the type of connectivity, the power to be transmitted and the area of application tend to play a vital role in the selection of the type of the coupling. Gear Couplings belong to the category of flexible couplings that are capable of transmitting…
The involute gear is very popular in industry. In this gear design article, we will define the involute gear and will discuss the design, applications, and advantages of the involute gear. Based upon the profile of the spur gear teeth, gear can be classified in two major categories: involute gear and cycloidal gear. How the…
Various types of cam follower are used for different types of applications. You can see an application of the cam follower in another article here about the internal combustion engine. The basic purpose of using the cam follower is converting the rotary motion of the cam to the translating or oscillatory motion of the follower. Before…
Cam is always rotated by a prime mover. We will discuss the differential method for finding relation between the angular velocity of a cam and the linear velocity of a follower. And, from that relation we will calculate the velocity of follower as the angular velocity of cam will be known. The overall method is…
Lets us begin with a basic question. How do we transmit rotary power from one place to another? Well we have numerous solutions and one of the solutions would surely be a V-Belt. A simple way of defining any belt drive would be imagining two separate rollers being bound by means of a thread that…
What is Gear Backlash? It is the clearance between two mating gears. Most of the gear train applications you see around are always contains certain amounts of backlash in it. For some of the application, gear backlash is helpful and thus kept intentionally and for some, it is not desired at all. The gear backlash prevention techniques…
The spur gear is manufactured by the gear hobbing method. Often you design the gears and source it from the suppliers. What if the supplied gear is of different pressure angle than you required? Before going to the methodologies of how to measure the pressure angle of the gear, let’s see some of the important gear terminologies related to our…
