Keywords: hydraulicsupport; Cosmos / Works; FEA1 hydraulic support bracket structure of three-dimensional model is very complicated physical structure to be completely by the finite element analysis, the calculation is very large, very difficult to calculate because Pán: National Eleventh Five-Year Technology Support Program topics (2006BABI1B05); 2006, Qingdao Municipal Science and Technology Development project (06-2-2-18 a jch); 2007 in Qingdao Municipal Science and Technology Development project (O7-2-3-4 a ich); 2007 Natural Science Foundation of Shandong Province Project (Y2007G02) hydraulic support in the establishment of this model, the need for appropriate simplification, the result will not affect the parts omitted. Simplification of complex parts. In this paper,[link widoczny dla zalogowanych], bottom-up modeling approach, first using SolidWorks software provides feature modeling tools through part model, based on the complete assembly in this model. I, l, \! L-, -,. , _l,. ,;,:; Stone l, ll, Stone I, \! _I,; -, Type in the heat transfer coefficient, taken = 13; - radiating area, A = 27.2m; △ ? - cabinet temperature, the design The maximum oil temperature to 100 ℃, room temperature 20 ℃, the temperature difference At = 80qC. (2) rocker arm is designed for water cooling of water in water flow 100L/min, the water quality of m = pv = 6000kg /} l. Test water inlet temperature is measured 2O ℃, outlet water temperature is 32cI =,[link widoczny dla zalogowanych], ie temperature = 32-20 = 12oc. Calculated the amount of water cooling 2 = CmAt = 10.2x10kJ / h. H = total heat dissipation at 1 +2 = 10.48x10> 9.46x10 (total heat), to meet the design conditions and in normal working hours in the basic thermal equilibrium. 2 Conclusion (1) the amount of liquid oil tank is heating of coal mining arm gearbox problem the key factors. When the factory in the coal mining, oil should be specified capacity. (2) Environmental impact of temperature on the heat Shearer deserves attention. (3) gear oil heat stirring quantitative method by experimental verification with the actual situation. Through this analysis we can see. Rocker Electric Shearer on gear box drive system design, thermal analysis must be calculated to determine whether the conditions of its transmission system to meet the cooling requirements at work; and thus infer the need for enhanced cooling system or to install cooling parts . With the rapid development of computer technology through advanced design of a finite element method analysis of gear box Shearer Cutting calculated. Then CAD, Solidworks, ANSYS-aided design software such as temperature field simulation experiment will study heating of coal mining rocker gear to a new level. References: [1] Zhao Hongmei, Liu new.
