B. Yapalaparvi Department of Electrical and Electronics Engineering Department of Mechanical Engineering Hirasugar Institute of Technology, Nidasoshi, Karnataka Hirasugar Institute of Technology, Nidasoshi, Karnataka (India) (India) Abstract The wheelchair is one of the most commonly used assistive devices for enhancing personal mobility, which is a precondition for enjoying human rights and living in dignity and assists people with disabilities to become more productive members of their communities. For many people, an appropriate, well-designed and well-fitted wheelchair can be the first step towards inclusion and participation in society. When the need is not met, people with disabilities are isolated and do not have access to the same opportunities as others within their own communities. Providing wheelchairs that are fit for the purpose not only enhances mobility but begins a process of opening up a world of education, work and social life [1]. The development of national policies and increased training opportunities in the design, production and supply of wheelchairs are essential next steps. Every human being need to move from one place another to fulfill his requirements and to accomplish that requirements he will travel from one place to another place by walking which is a basic medium of transportation. But it is exceptional in case of physically disables (Persons don’t have both legs). In order to support and help such a person’s we designed a special manually lever operated wheel chair.

  • Friction-Producing Mechanisms of a Bicycle Chain
    Friction-Producing Mechanisms of a Bicycle Chain _ Effectiveness of Chain Lubricants for Reducing Frictional Losses Copyright ©2014 Friction Facts, LLC rev 5-13-14 Overview The friction-producing mechanisms of a bicycle chain moving through a derailleur-style drivetrain are unique and relatively complex. These friction- producing mechanisms arise from friction created in individual links, which are subjected to multiple regions of both high and low pressure, reciprocating sliding forces, and stiction. As such, testing methods for chain efficiency and chain lubricants must address these complex mechanisms. This paper explores the details of how friction is created in a bicycle chain in a modern-derailleur style drivetrain, the role of chain lubricants to minimize friction in a chain, and the limitations of commonly-used friction test methods. This paper also suggests a testing process to analyze the efficiency of a chain and lubricant in a manner specifically relevant to chain friction-producing mechanisms. Friction-Producing Mechanisms of a Chain From a simplified standpoint, the friction created (wasted energy) by a roller chain is generally proportional to: [chain tension] x [sine of lateral deflection] x [link articulation angle at a given engagement or disengagement point] x [number of link articulations per unit time at that point] x [total engagement and disengagement points in the complete drivetrain]. This basic formula has been demonstrated by multiple drivetrain studies and, more recently, by tests performed by Friction Facts. Essentially, friction is created each time an individual link, under a finite level of tension, bends (articulates) as it engages or disengages the teeth of a cog, pulley, or chainring.

  • Cannon Cyclery Chain and Cable Fixes Clinic Guide FINAL
    Curtis Henry, Pro Cycling Mechanic www.cannoncyclery.bike Roadside Repairs and Maintenance With the proper maintenance and care of your ride, you can minimize your downtime on the trail. However, flat tires and broken parts are almost unavoidable and knowing how to handle them properly can save your ride or race! Begin your ride by being preparing with the basics of what to carry with you at all times when out riding. You’ll need: • A spare tube that it the right size for your bike and a patch kit. • A CO2 powered inflation system and at least 2 spare CO2 cartridges. • Tire tools for removing and installing your tube. • A multi-tool with a chain tool and multiple wrenches/Allen keys. • Some anti-flat tire mojo. What I also recommend for the road: (A bit overkill I know…) • Zip ties and a small roll of tape. • An extra section of chain that matches your bike or a master link. • A small (well sealed) bottle of chain lube. • An extra shift and brake cable. • Cannon Cyclery Business Cards! Golden Rule Bike Maintenance Facts • Proper chain lubrication is one of the most beneficial and often overlooked pre-ride rituals. Ideally you should spray or drip lube on the chain every other ride. The best practice is to apply a thin coating to the chain only and then wipe off the excess with a dry rag. When the chain is properly lubed it will shift and run quietly, wear longer, and keep other drive train components lasting longer. • Creaking and popping sounds coming from your steed are not normal and are usually a sign that something is loose, worn, or cracked.
