Component Alignment Technology

The parts feeder component alignment technology has been a mature technology since the industrial automation became popular since the early 1970s. But miniaturization of the parts to be aligned has increased the difficulty levels of alignment methods. For parts aligning, ...

Rotary to Linear Motion

A slider-crank mechanism is a typical design which converts rotary motion into linear motion. It is achieved by connecting a slider and a crank with a rod. This mechanism is also utilized as a system that converts the reciprocating linear ...

The Need for Speed: High-Speed Automation Design

In the midst of adverse market conditions, automation devices must be manufactured to a higher standard in terms of quality, cost, and delivery time. The requirements of making automation devices high-speed not only involves increasing the productivity per hour but ...

Bearing All: Retaining Methods

A bearing by definition is a part of a machine that bears friction, especially between a rotating part and its housing. The architectural definition is a structural part that supports weight. A ball bearing is a rolling element bearing that ...

Give Your Design a Boost: Boost Mechanisms

A mechanism designed to generate a large force from a small force is called a boost mechanism. Mechanical components that constitute this boost mechanism include links, levers, screws, wedges, gears, and pulleys. For lightweight arms of robots, the link mechanism is ...

Surface Finishes: Hard Chrome Plating

The most common and long-established method of decorative plating on steel is copper-nickel-chrome plating also known as ‘chrome plating’. In recent years, nickel-chrome plating (semi-bright + bright plating) is also common for its superior corrosion resistance and aesthetic properties. These ...

Surface Finishes: Heat Treatments

Heat treatment is a type of surface treatment that includes hardening and thermal diffusion. Both use heating to apply the surface treatments to the work piece. There are two types of heat treatments hardening and thermal diffusion. In this post, ...

The Technique of Losing Weight: Part Two

Strength and Shape Design Considerations After looking at ways to use different plastics instead of metal in last week’s post, we will examine shape and material in this week’s post. Weight reduction is a design task assigned to many engineers, ...

The Technique of Losing Weight: Part One

In response to concerns about global warming and depletion of subterranean resources such as petroleum oil, the automobile industry is rapidly shifting from gasoline-based cars to hybrid and electric cars. As a CO2 emissions-reduction measure, many countries are competing to make ...

Rotary Bearing Fits and Tolerancing

Rotary bearings are machine elements that support rotating shafts accurately while providing low friction conditions. In order to maintain a stable bearing performance over a prolonged duration, appropriate bearing fit design considerations are required to avoid any negative effects ([Chart 1]) ...
