单筒冷却机传动装置设计

摘要：冷却机用于冷却烧出的高温熟料。通过将物料在筒体中回转前进与对流冷风产生热交换，达到冷却的目的。本课题研究的主要内容包括主传动和辅助传动功率的设计计算；大齿圈和小齿轮副设计；减速装置的选择设计；齿轮轴设计；齿轮与轴的强度校核；相关传动装置的结构设计。在本课题中交流电动机改为直流调速电动机，看火工可以根据窑况、料层的厚薄以及二次风的温度进行手动调节单筒冷却机的转速以求获得合理的工况, 为看火操作创造了有利条件。加强大小齿轮罩壳的密封，保持润滑油的清洁。在运行到800r/min以上还没有引发共振时快速提速到900r/min；检查调整好小齿轮和齿圈的间隙,平时加强系统维护,尽可能减少啮合冲击力,检查齿轮面并清洗换面。冷却机中部直径大,可大大增加冷却容积;加以适当的主电机使冷却机体转动加快,使熟料与空气得以充分热传递。这个课题充分考察了4000t/d冷却机传动装置设计的可行性，是对大产量冷却机传动的可靠性的设计。

Design of the Gearing of the Cooling Machine

Abstract:Cooling machine is used for cooling the high temperature chamotte. Material in the cooling m阿chine exchanges heat with convective cold blast when it is advance reelingly. The research mainly consists of the design of the main device , accessory drive , big Gear and small gear, deceleration devices, gear shaft , gear shaft strength check-up and something else.In the topic,alternating current motor is instead of direct current speed regulating motor. Workers can adjust single-speed of cooling machine to a reasonable working under the conditions of the fire kiln, the thick layers and the secondary air temperature .It creates a favorable operating condition .To strengthen the size of the sealed gear and maintain the cleanliness of lubricants , is necessary. In operation to 800 r/min ,more resonance had not been triggered when accelerating to 900 r/min rapidly. Examining and adjusting small gear and big gear is in an effort to strengthen the system in peacetime maintenance .To minimize the impact of meshing and gear check for surface and surface cleaning .The created Cooler Central diameter , can be greatly increased cooling capacity. It will be appropriate to turn the main motor rotation speed up at the cooling body so that clinker and the air is full of heat transfer. This issue fully investigated the feasibility of 4000 t / d cooling Drive, is the design of the large cooling ma chine’s transmission reliability .

Key word:Cooling machine; Drive; Gear; Gear enclosures.
