A worm shaft is a type of gear with a raised ridge that provides a surface for ball bearings and is commonly found in steering boxes and electric motors. It reduces speed and increases power, and is used in power tools and fishing reels. Heavy oil is the best lubricant for worm shafts. A worm […]
A worm gear winch uses a worm gear and a disc-shaped flat gear to create torque, resulting in a higher gear ratio than other winches. This design is less efficient but preferable for fast-acting self-locking winches, commonly used for boat trailers, low-bed car transport equipment, and tow trucks. A worm gear winch uses a specialized […]
A worm gearbox has a helical output gear and a worm input gear, providing high output torque values in a small package. It offers space savings, low reduction ratios, and high shock load capabilities at a low cost. However, it requires reduced power and has lower long-term efficiency levels. A worm gearbox is a type […]
A worm gear motor consists of a threaded gear, an interlocking gear wheel, and a motor. It amplifies the rotational force of the motor and is used in heavy industry, transportation, and small tools. The force required to drive the wheel depends on various factors, and the motor needs frequent lubrication. It is self-locking and […]
Worm gears transfer power through 90 degrees, often with a change in torque and a reduction in size. They work in one direction and are typically found in elevators, escalators, and industrial machinery. They consist of two shafts and two gears and are unidirectional, making them ideal for places where power does not need to […]
The blaster worm infected hundreds of thousands of Windows-based computers in 2003, exploiting a security hole that had been patched a month prior. It used infected computers to launch DDoS attacks on servers distributing security patches. ISPs blocked traffic on port 135 to prevent further spread. The blaster worm was malware that first spread to […]
Guinea worm disease is caused by parasites that live on water fleas and is contracted by drinking water containing fleas. The disease is prevalent in remote areas of Africa, India, and Asia. The World Health Organization has launched a campaign to eradicate the disease, and by 2008, incidents had dropped to around 5,000. Prevention is […]
The Morris worm, created by Robert Morris in 1988, was the first computer malware to spread over the Internet, infecting at least 6,000 computers and causing numerous servers to fail. Morris claimed he didn’t intend harm, but a programming error caused the worm to overload computers. The incident prompted the creation of CERT/CC and Morris […]
A poll worm is a real-time poll conducted during political debates using cell phones to generate data on public responses. The data can be used to adjust politicians’ approach to the debate, but it may not always provide an accurate picture of audience response. Worm poll analysis can be a powerful tool for identifying weak […]
