LIST OF LITERATURE USED:

Introduction

Course work consists of points, the execution of which is sequentially optional. Each item introduces the student with the appropriate nodes and rules for choosing planting and quotas for them. The orientation of each item corresponds to the most widespread nodes in mechanical engineering. By the end of the course project, the student needs to master the rules for choosing cylindrical fits, bearing fits, rules for choosing fits for threaded joints, calculating dimensional chains, familiarize himself with the equipment selected by the teacher for measuring actual sizes.

Conclusion

As a result of the work done, the theoretical material issued by the design drawing was studied, as well as practical tasks were completed on the following topics:

1. Tolerances and fits of smooth cylindrical joints.

2. Purpose of splined joint fit.

3. Define tolerances and limit deviations for dimensions in a dimension chain in two ways:

4. Calculation and selection of rolling bearing fits.

5. Select tolerance fields, set basic parameters, limit deviations, and threaded connection tolerances.

6. Normalizes the accuracy of the part included in the assembly.

As a result of completing the tasks, I learned to work with standards, I studied theoretical information on topics that affect this course work, which, as a result, will allow me to put my knowledge into practice.
