Characteristics and classification of disc springs

图片
  The disc spring is a washer-type spring with a frusto-conical section made of sheet metal or forged blanks. It is often used in heavy machinery (such as presses) and cannons, aircraft and other weapons, as a strong buffer and vibration damping spring, as a compression spring for clutches and safety valves of vehicles and tractors, and as an energy storage element for motorized equipment. Features of Disc Springs 1. High rigidity, strong buffering and vibration absorption ability, can withstand large loads with small deformation, and is suitable for occasions with small axial space requirements. 2. With variable stiffness characteristics, this spring has a wide range of nonlinear characteristics. 3. Using different combinations of the same disc spring can change the spring characteristics in a wide range. The combination of involution and stacking can be used, and the combination of different thicknesses and different numbers of sheets can also be used. When overlapping, the more the

3 Tips for You to Find the Best Suitable Tires

  3 Tips To Find the Best Suitable Tires Once you know what size tire is right for your car, you need to be able to choose between different  types of tires . Tires may look similar, but they can be optimized to fit very different conditions and uses. Consider the following: What are the weather conditions? Where will I be driving? What is my driving style? ♦ What Weather Conditions? Your tires must cope with a variety of weather conditions: rain, heat, snow, ice, etc. All of these affect the performance of your tires, so to ensure your safety, you need to buy tires that can operate not only in the most common climates, but also in the most extreme conditions you will face. Relatively warm climates If the temperature will not fall below freezing, you may choose to purchase all-season tires and/or summer tires. AT Tyre The climate is seasonal In winter, the temperature is below freezing. To maximize your safety in all the conditions you need, you need a set of all-season tires. Severe w

What Are Reefer Vans Used For?

  What's a Reefer Truck ?   "Reefer" is slang for refrigerated. The truck is your standard semi-cab. However, the reefer really is just the trailer. A "reefer truck," then, is a semi pulling a refrigerated trailer, designed to haul perishable goods. These trailers differ from cooling vans, which are just insulated and vented. What makes a reefer trailer different? Reefers include an active cooling system. Thus, you can transport frozen as well as refrigerated freight. A reefer could also be temperature adjusted to haul heated goods as well. However, this is much less common. You can find reefers using a couple of different cooling methods. You may see both diesel-powered generators and cryogenic cooling systems. Let's take a closer look at exactly how trailer cooling works.   How Reefer Units Work   Reefer units operate on a  closed system . Removing heat and maintaining a steady temperature is what a refrigerated trailer system is all about. They operate by

What are the advantages of scissor hydraulic lifting platform

图片
  Scissor lift   is a wide range of special equipment for aerial work. Its scissor mechanical structure makes the lifting platform have high stability, wide working platform and high bearing capacity, so that the aerial work range is larger, and it is suitable for multiple people to work at the same time. It makes work more efficient and safer. With large platforms to accommodate both people and materials, scissor lifts are popular for manufacturing and industrial projects. They provide a safe and reliable environment for workers to complete projects with heights involved. With criss-crossing braces, scissor lifts are capable of vertical movement. This X-pattern which compresses and extends is also known as a pantograph. What truly makes the scissor lift a valuable tool is that it can extend up and then collapse small enough to be easily stored, a value piece that made it a true rival to the traditional ladder. Scissor lifts are available powered by an electric or diesel engine. Electr

What are the Different Types of Insulators?

  Obviously, if the transmission line is not properly insulated from the support of the tower or pole, then the current will flow in the direction of the ground through the tower and thus become dangerous. Of course, the transmission line is always supported by   insulators   placed on the poles. Insulators used for towers must have high mechanical strength, high resistance, and high relative permittivity, etc.   Types of insulators These are divided into different types according to their ratings, which include the following. These are used in transmission and distribution systems, where each insulator consists of several insulating discs. If one disc uses 11kv voltage, the remaining discs use 66kv voltage.   AC Standard Glass Insulator Insulators are divided into five different main types.   Post Insulator Shackle Insulator Pin insulators Strain insulators Suspension insulators   1. Post insulators Post insulators are commonly used in substations or power generation substations.   Po

What should I be looking for in a sun sleeve?

  When the sun breaks through the sky, it's a great day to play golf. However, the sun can also bring harmful UV rays. You can be on the golf course for several hours per round, so  sun sleeves  are a great way to stay protected during the hot hours. Therefore, the  best sun sleeves  will provide UV protection on the course. Sun protection isn't the only thing they should give you, though. They should also keep you cool, provide plenty of flexibility, and stay in place without slipping on every swing. Great for outdoor sports For anyone who plays outdoor sports, runs, tries CrossFit for runners, etc., these may be the best choice for you due to the construction of the sleeves. The stitching of the sleeves takes into account muscle anatomy for a more comfortable, fluid sleeve that won't restrict your range of motion. Best for UV protection If you're a cyclist, many of the activities you do outdoors in the field, on the track or even on your bike will be upgraded by this
