How to write a mechanical design specification?How to write a mechanical design specification

The specific content required for the mechanical design specification includes:

1. Title. The name of the design project.

It is required to be clearly described.

2. Task book. The purpose of the design and the requirements of the task should be stated.

Requirements: Briefly describe the main content, characteristics, parameter performance, results to be achieved and acceptance criteria of the design.

3. Technical scheme. Describe in detail the technical scheme, process plan, production plan, etc. to achieve the design, and focus on the solution of technical difficulties and the required resources.

4. Design resource requirements. Mainly the requirements for cost, personnel, external support, internal support equipment, etc.

5. Design plan. Achieve the important time nodes of the design and the final completion time.

6. Miscellaneous. Different designs have different requirements.

Content from user: Yang Yanxiu.

Mechanical parts design course design competition.

Manual design title: single-stage cylindrical gear reducer.

Class: Mechanic 3089

Name: Ma Mingqi, Ke Zhenkun, Zhang Xinqiang, Hu Shaohui, Li Gang.

Instructor: Chen Changxiu.

Completion Date: January 1, 2010.

Shaanxi National Defense Vocational and Technical College.

Foreword: This manual is based on the course design competition - single-stage spur cylindrical gear reducer. According to the working performance and structural characteristics of the reducer, a detailed description is made, and its main content is systematically and scientifically arranged in accordance with the mechanical force analysis, bearing capacity, structure, working principle analysis, parts audit, etc.

Combined with the single-stage cylindrical gear reducer, it has the characteristics of strong theory and strong time. This manual not only carries out a large number of targeted calculation and verification work, but also gives a detailed explanation and force analysis of some parts or a component, and also gives a visual diagram.

This manual is closely combined with "Fundamentals of Mechanical Design" and "Mechanical Parts Course Design" and other information books. Under the guidance of the machine design teacher, he gave great help to complete the design. The latest national standards are used, so the tightness has been improved.

Due to the limited knowledge level of the designer and the tight design time, there are inevitably many deficiencies in the design process, and even mistakes and omissions, as well as the inconvenience caused, please understand the audience, I hope the teacher and students will give criticism and correction and your valuable opinions, thank you.

Department of Mechanical Engineering.

Major: Mechanical Engineering and Automation.

1. Formulation and description of the transmission plan.

2. Introduction to the structure and performance of the reducer.

The first thing to do is make a cover.

Catalog contents.

1. Chapter 1 Overview (including preface, and design brief).

2 Chapter 2 The designed structural diagram, the sketch can be, that is, the appearance layout diagram 3 If there is an outsourcing agency, such as the power supply part, add a chapter to introduce the calculation of 4 power and cloud parameters.

5. The selection and calculation of each device is mainly to explain why you choose this way, to have data basis, and to have a complete calculation process and inference.

6. Mechanical strength calculation (same as above6) Each part is done separately in chapters, which should be detailed, and the calculation and selection of materials, structures, and sizes should be available.

7. The introduction of accessories, a separate section for large parts, and a section for others such as bearings, sealing rings, etc.

Among them, it is necessary to consider the working environment and place, heat dissipation, lubrication, materials and other factors to determine the appropriate appearance volume and service life, everything must be explained with data, drawings should be attached, assembly drawings and parts drawings should be made.

How to write a mechanical design specification, it should be said what your mechanical design does. Write according to the design content, I have done a lot of mechanical design before, there are drawings and manuals, you can refer to how to write.

There is no fixed form of the prospectus, and the common ones are as follows: The title of the graduation statement is the eyebrow of the instruction manual, which should be carefully scrutinized and fully considered from all angles as much as possible to choose the most suitable one. In principle, the title should be simple and clear, and reflect the main content of the graduation statement, so that readers can see at a glance what the central content of the statement is about, and avoid being general and vague.

The language should also be complementary, and at the same time be able to attract the reader's attention.

The title of the graduation statement should not be artistically processed like ** and prose to arouse the reader's curiosity. The title of the manual should be so that people can understand its manual directly at a glance. Therefore, the proposed topic should adopt a direct and positive method to improve the content of the manual, rather than adopting a peculiar artistic technique.

The title should not be too long, try to be less than 20 words. The relevant parts of the manual were all copied, and after inspection, there were no more problems, and it was bound into a book, plus the cover.

The cover of the graduation prospectus should be simple and generous, and the title, school, department, name of the instructor, author's name, and date of completion should be written. The name of the author of the title of the manual must be written on the skin, not on the patch inside. The cover page can be written like this (different schools have different requirements):

Graduation design specification for university mechanical major.

Professional Class: First Name:

Student ID: Instructor:

20 years, months, and days.

The back cover can be a blank sheet of paper and then bound into a book.
