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。
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 threeresearch 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 position and thickness.
