  • Have knowledge and skills for the calculation, design and testing of machines

Description

The subject Mechanisms and Machines II, centered in the description, interpretation and calculation of accionamientos and his auxiliary elements, completes the integral training in the field of the mechanisms and the machines. It is a key element for the consolidation of learning, as it allows students to apply in the design of machine elements that has been worked on in other subjects. On the other hand, it is a key source of theoretical and applied knowledge for the professional practice of the mechanical engineer with regard to Machine Design.

  • Selection of market components
  1. GEAR TRANSMISSIONS
  • Gears and gear trains
  • Gear theory
  • Geometry of gears

  • Conical and hyperbolic gears

Evaluation system

The calculation for the Final Grade (NF) of the subject is:

NF = 0,35 Ex1 + 0,35 Ex2 + 0,1 Inf + 0,2 Pr

  • NF: Final Note
  • Ex1: 1st Partial Examination (35%).
  • Ex1: 2nd Partial Examination (35%).
  • Inf: Work Report Note (10%) = (INF1 + INF2 + INF3) / 3
  • Pr: Practice Note (20%) = (P1 + P2 + P3 + P4 + P5) / 5

Clarifications:

  • The minimum grade for each of the exams is 3,5. In the event that any of the grades for the Ex1 and Ex2 activities is below the minimum grade, the final grade for the subject will be limited to 4.
  • Minimum mark of Practices (Pr) is 4. In case the mark of Practices is below the minimum mark, the final qualification of the asignatura will remain limited to 4.
  • Minimum grade of Work Report (Inf) is 4. In case the grade of Work Report is below the minimum grade, the final grade of the subject will be limited to 4.

Recovery:

  • It will be possible to recover all the evaluation acts separately (1st Partial Examination, 2nd Partial Examination and Practices).
