PM14慢速绞车的设计China mine small grain mainly refers to the car and dispatching winch winch, it has experienced two stages of imitation, self clesign. In the early days of liberation, the small mine cars used in Jap a n were made in Japan and the Soviet Union, so the small mine winch produced at that time was also the product of Surveying and mapping the imitation of Japan and the Soviet union. After 1985, these products have been picked up, and the Soviet winch has been improved, and in 1964 entered the stage of self design. The Huainan coal machinery plant has designed and manufactured the cycloidal gear winch and the small tooth differenee drive winch. Xuzhou mining equipment factory was designed and the cycloid planetary gear transmission lines of cars, some factory also produced the design of dispatching winch 25kW Xuzhou, Huainan Jinzhou mining machinery factory has clesigned and manufactured a power dispatching winch, 40kW 55kw.Winch is gen erally experienced two stages of imitation and self design, until the 80s use is the imitation of the old products in mid 80s began to design new winch, mainly aimed at the effect of the mechanical design of the low rate of worm gear, slow and fast rope back work and other aspects of fundamental improvement・In terms of mine winch standardization, 1967 formulated the staridard of dispatching winch, winch department in 1971 to develop a standard・ In 1982, the above two standards were revised, and the standard was JB965 - 83, JB1409 - 83.In our country, the winch is mostly planetary gear drive, and the structure has four basic forms・1. way shaft typeThe utility model is characterized in that the vertical shaft is penetrated through, and the rigidity of the whole machine is strong, and the meshing precision of the gears in the running process can be ensured. Therefore, the utility model has the advantages of small noise and long service life, and the structure parts are simple, easy to manufacture and maintain, and the cost is lower・2. floating typeThe utility model is characterized in that the mechanical component of the winch is in good state of force because of adopting a floating piece, so the noise is obviously decreased and the service life is longer・3. and half embeddedThe utility model is characterized in that a part of the machine is embedded in the roller, and the driving device is arranged in the inner part of the roller and the end part, and the structure is compact, the volume is small, and the weight is light. However, the rigidity of the structure is poor, and the accuracy of the gear in operation is difficult to guarantee, which makes it difficult to further improve the life and reduce noise・ And parts of higher technical requirements, manufacturing difficult.4. fully embeddedThe utility model is characterized in that the motor is all arranged inside the roller, and the driving part is arranged at the end part of the roller, so that the whole machine is compact in structure, small in size and convenient for carrying・Development status of foreign winch in 1. 3. 2Foreign small mine cars are widely used, and there are many manufacturers・ The Soviet Union, Japan, the United States, Sweden and other countries have made small mining winch・The types and specifications of small mine cars used abroad are more specifications・ For example, the dispatching winch has tractive power from 100kg f to 3600kg F, power driven, hydraulic and pneumatic・ The working mechanisms are simple, double, and frictiona 1. The transmission types are belt drive, chain drive, gear drive, worm gear drive, hydraulic transmission, planetary gear drive and cycloid gear drive, etc・・ Among them, planetary gear transmission is more・The development trend towards standardization series direction, to the small size, light weight and compact structure to the direction of development; efficient, energy saving, long service life, low noise, multi-function universal, high power, simple shape, smooth, beautiful and generous direction・The development trend of mining winch in foreign countries and its mechanical design situation have the following characteristics・(1) to small size, light weight and compact structure・ Because of the narrow coal mine work environment requirements winch with small volume and light weight, and strive to be the main components of all the countries in the prime mover, winch transmission device, the working cylinder, brake operation and other parts of the base of comprehensive and overall layout in a system, make full use of the space to improve the compactness, good shape closed・ For this reason, some drive parts are placed inside the roller, some are close to the end of the roller, others are embedded in the cylinder, and some of the base, bracket and reducer are cast into one body.(2) develop towards high efficiency and energy saving・ The developed countries in the world, such as the Soviet Union and Japan, optimize the design of various 。
