The design of new amusement equipment should stipulate the service life of the whole machine and main components. The service life of the whole machine shall not be less than 23 000 11. Metal materials used for important mechanical parts, mechanical properties, thermal properties and welding properties should meet the requirements of working conditions. When the passenger support is in normal operation and activation, braking and emergency, the force exerted by the person on the armrests, supports, ankles and walls should not be less than 500, for adults, new children's play equipment. It should not be less than RMB/person. The design of the new amusement equipment calculates the wind load under the working condition according to the maximum working wind speed of 15 claw/^. Safety factors greater than or equal to 5 for critical shafts, pins and critical welds, and 3.5 or higher for general components (brittle materials 28>). The classification of new amusement equipment is related to the development of new amusement equipment. Due to the wide variety of new amusement equipment, the structure and movement form are different. It is impossible to establish a standard for every new type of play equipment. Instead, recreational facilities with similar structures and movements are classified into a category, and standards are set according to the category. The classification of new amusement equipment is mainly based on its structure and movement form, that is, new amusement equipment with similar structure and movement is classified into a category rather than the name of the amusement facility. Each type of amusement ride is named after a common representative of the new amusement equipment. The new amusement equipment is the basic type, and the new amusement equipment with similar structure and movement form is similar. There are many kinds of new amusement equipment and different transmission methods. The main types are as follows. 1. Transmission mode around the central axis This type of transmission is commonly used in mechanical transmission and hydraulic transmission, as well as gear transmission and chain transmission in mechanical transmission. Table 3-1 lists several common transmissions around the central axis. Serial numbers are usually used for rotation around a central axis. Transmission system: motor worm reducer - chain drive - central shaft rotation, the whole machine is suitable for small electric entertainment entertainment turntables, small swivel chairs and other entertainment facilities. When large and medium-sized new amusement equipment adopts this transmission method, choose non-self-locking worm reducer. Chain drive, easy to manufacture, easy to install and adjust 2 Suitable for large, medium and small new entertainment equipment such as air swivel chairs. Adopt bevel gear drive, compact structure. However, machining and installation adjustments are more demanding. Transmission system: motor ~ wheel set - central shaft rotation 4 gear reducer - canopy gear backup machine, planetary reducer, etc. 1. Flexible friction drive systems commonly used flexible friction drives include belt drives, traction wire rope drives, etc. 2. Flexible meshing transmission system commonly used chain drive (sleeve chain, curved chain), belt drive (synchronized toothed belt) 3. The fluid transmission system mainly includes pneumatic transmission, hydraulic transmission, hydraulic transmission and so on.
