摘 要

本文主要介绍了 MR141毛刷式锯齿剥绒机的总体设计和机架部设计。MR141型毛刷式锯齿剥绒机专为从轧花机排出的棉籽上剥取短绒之用，调整好不同的配车规格，分别可以剥取头道、二道或三道短绒。而且 MR141型剥绒机在原机的基础上作了重大改进。MR141 毛刷式锯齿剥绒机主要由六个部分组成，分别是机架部，工作箱部，锯筒部，毛刷部，喂籽箱部，自动喂籽机构部。由于本文作者研究课题的原因，本文侧重于总体结构和机架部的设计，总体结构则主要是对机器的结构，及主要受力部件的强度校核，和机器的传动设计。机架部则主要是机架的各组成零件的设计和强度校核，机架部是剥绒机的框架，有一定的强度要求。

Abstract

This text introduced primarily the MR141 hair brush type teeth of a saw shells the total design of Linter to design with the machine a department. The MR141 type hair brush type teeth of a saw shells Linter to spend from Cotton Gin just for the cotton that machine eject ascends to shell to take the strip linters use, adjusting the good going together with the car specification differently, canning shell to take respectively a way, two ways or three strip linters.And the type of MR141 shells Linter foundation in original machine ascended to make the important improvement.
The MR141 hair brush type teeth of a saw shells the Linter the main being constituted by six parts, respectively is machine a department, work a department, saw the department , the hair brushes department, hello linter a department, automatic hello linter organization department.Because this text the author studies the lesson a design for of reason, this text laying emphasis in total construction with machine a department, the total construction is then primarily is to the construction of the machine, and is primarily matched by the strength of the dint parts, spread to move the design with the machine.Machine for then primarily is machine a design for of eachly constituting spare parts with strength matching, machine a department is frame to shell Linter, having certain strength requesting.

Key phrase：The hair brushes Total machine Machine
