The disc spring is a kind of compression spring. Because it has the advantages of simple structure, small installation size, large carrying capacity, variable stiffness, etc., it is widely used in industrial products. It mainly expounds the application of the disc spring in the adjusting mechanism of the opening and closing roof system of the large-span movable building steel structure. Based on the load characteristics of the opening and closing roof, the specific analysis and discussion of the selection and calculation of the disc spring is made.

Foreword:

The opening and closing roof is a novel architectural form that enables part or all of the structures to be opened and closed in a short period of time. The building can be opened and closed in two different working states according to actual needs. The design of the opening and closing roof integrates multi-disciplinary technologies such as building structure, machinery and automatic control. The opening and closing motion of the roof is completed by the mechanical system under the accusation and coordination of the control system, and the vertical and vertical adjustment mechanisms are opening and closing roofs. The more critical part of the mechanical system. The application of the disc spring in the vertical and longitudinal adjustment devices of the mechanical system of the opening and closing roof is mainly introduced, and the design calculation of the disc spring is discussed in accordance with the practical requirements of the opening and closing roof.

1. Opening and closing roof mechanical adjustment system The opening and closing roof is mainly composed of fixed roof, movable roof, mechanical adjustment system and other parts. The mechanical adjustment system is the intermediate connecting body of the movable roof and the fixed roof, and is also the main device for realizing the opening and closing of the roof. In addition to carrying self-weight loads, active roof covers may also be subjected to wind loads, snow loads, earthquake loads, temperature loads, and additional loads caused by differential settlements, so that the active roof is in a different state of space, so the active roof is fixed. The relative position of the roof is constantly changing. In order to adapt to the characteristics of the opening and closing roof, the mechanical adjustment system must be provided with adjustment devices, including linear displacement adjustment and angle adjustment devices, to avoid vertical overload damage and vertical railing in the mechanical adjustment system. This article mainly discusses the linear displacement. Adjustments.

1, opening and closing roof mechanical adjustment system features:

The bearing capacity is large. Due to the rigid structure of the mobile roof, the self-heavy load is large, and a roof is often measured in hundreds of tons or even thousands of tons. It is necessary to adjust the system to have sufficient carrying capacity.

2) The deformation range is large, and the deformation of the movable roof and the fixed roof is from a few millimeters to several hundred millimeters. At the same time, the economical and space structure requirements are taken into consideration. This determines that different types of adjustment devices are required to accommodate larger adjustments. Quantity and adjustment range;

3) The operating speed is low, and the moving roof is slow, usually about 3m/min. The high reliability and long service life of the building requires the mechanical system to operate safely and reliably while reducing the frequency of maintenance as much as possible. To ensure its adequate service life.

2, the characteristics of the disc spring:

The disc spring, also known as the Belleville spring, is a non-linear damping and cushioning element. It has been widely used in low-speed and heavy-duty equipments in petroleum, chemical, mining and metallurgical industries. Its own characteristics:

1) It has large rigidity, strong shock absorption and vibration absorption capacity, and it can withstand large loads with small deformation. It is often used in occasions where the axial installation size is small;

2) It has variable stiffness characteristics and has a wide range of nonlinear characteristics;

3) The same disc spring using different combinations can change the spring characteristics in a wide range, can use combination, superposition and compound combinations.

The disc spring has the irreplaceable advantages and characteristics of the ordinary spiral spring, can well adapt to the heavy load and large deformation conditions of the opening and closing roof system, meet the requirements of the use of the mechanical adjustment system, and is regarded as shock absorption in the mechanical adjustment system. Buffer, adjusting damping element use.

grilled:

Insert a fork on the bottom of the tomato and bake it on the fire for about 10 seconds. The skin of the tomato will crack. After cooling for a few seconds, remove the skin by hand. The peeled skin is complete.

(Roasting is what I think is the shortest time required in the three methods. The peeled skin is the most complete and convenient method!!!)

cook:

Pour clear water into the pot, and after the fire is boiled, add the tomatoes and cook for about 20 seconds. Use a spoon to keep turning the tomatoes over so that all the tomatoes can be boiled. Or put some more water in the pot and never had tomatoes.

After removing it, cool it for a minute and then peel off the skin, but the hand is still slightly hot, and it is not easy to hold it. During the peeling process, the tomatoes are slippery.

(Boiled, although the time required is not too long, but the time to cook the water, the time to cook the tomatoes, plus the cooling time, count it, at least 5 minutes. Moreover, a pot of water is also wasted, and Gas Feiha, although not much money, but over time, it may not be a scary figure.)

scratch:

Scraping with a spoon is also a way. The choice of spoon is more important, the edge of the spoon should not be too thin, nor too thick. For example, with a tin spoon, tomatoes can break easily; but if you use a white porcelain spoon for soup, the edge of the spoon is too sleek and laborious. I think stainless steel spoons and plastic spoons are good choices.

(Scraping: This method seems to be the easiest to compare with the above two methods, but for me, it is the most laborious of these three methods. At the time of scraping, the intensity should be mastered and shaved too lightly. The skin and flesh cannot be separated, and if the force is too great, the skin will be scratched and it will be more troublesome if it is torn. Moreover, when it is not to be scraped, when it is torn, it is very difficult to use the nails. )
