闭锁式液力偶合器设计(离心式摩擦离合器).doc

摘 要
液力偶合器的实质是离心泵与涡轮机的组合，主要由输入轴、输出轴、泵轮、涡轮、外壳、辅室及安全保护装置等构成。目前对液力偶合器的设计有三种——研发类的全新型设计、相似设计和选型设计。工程中运用最多的是选型设计。本文试图在结合行业中液力偶合器的设计惯例，结合工作要求，进行选型设计和相似设计，并做重要部分的结构设计。由于某些原因，没有上传完整的毕业设计（完整的应包括毕业设计说明书、相关图纸CAD/PROE、中英文文献及翻译等），此文档也稍微删除了一部分内容（目录及某些关键内容）如需要的朋友，请联系我的叩扣:二二壹五八玖一壹五一
对输出轴孔和输入轴孔进行结构设计与校核，包括轴孔的强度校核和轴孔上的配合螺栓组强度校核。从各种液力偶合器的结构介绍中我们可以了解到，各种液力偶合器均需在转速差方面传递动力，转速差使输出转矩和功率均有损失，这是液力偶合器的内在缺陷。本次设计的闭锁式液力偶合器就可以有效地的弥补这方面的缺陷。闭锁式液力偶合器就是在限矩形液力偶合器上加装离心式摩擦离合器组成。本文也对输出轴孔的轴承进行了选择和校核。确定了泵轮和涡轮的厚度及合金材料成分。

ABSTRACT
Hydraulic coupling, in essence, is centrifugal pump and turbine combination. Enter from the main shaft, the output shaft, pumping round, turbine, shell, auxiliary rooms and pose a security device. Coupled with the current hydraulic design of the three-research and development of new types of design, similar to the design and type design. Engineering is the largest use of type design. This paper attempts to combine industry in the hydraulic coupling in the design practice, the combination of work requirements, selection and design of similar design, and to do important part of the structural design.
The output shaft hole and input shaft hole for structural design and verification, including the shaft hole and check the strength of the shaft with bolt holes on the group strength checking. From all kinds of hydraulic coupler introduced the structure, we can see that, all kinds of hydraulic coupler are to be in the rotation speed difference in power transmission, speed job torque and power are loss, this is hydraulic coupler inner defects. The design of the closure type hydraulic coupler can effectively to make up for the defect. Atresia type hydraulic coupler is limited in rectangular hydraulic coupler on centrifugal friction of the this paper, check the option of the output shaft hole’s bearings. Determine the pump and turbine wheel of alloy material composition and thickness.
