Advanced Course in Machine Elements (6 cr)

Objectives (course unit)

Student is able to choose and dimension the central machine elements and transmissions of mechanical engineering and power transmission as axis couplings, brakes, chain and timing belt drives. Student understands the joint alternatives of machine elements in mechanical engineering and power transmission and can dimension the central joints such as rivet joints, axis-hub joints (an adhesive joint and profile axes) and joints of the axes (the couplings and universal joints). Student knows the standard-based dimensioning, and can with machine elements form bigger units and components such as motor-coupling-gear units. Students knows e.g. the basics of balancing of rotating parts and alignment of shafts and is able proceed them.

Assessment criteria - fail (0) (Not in use, Look at the Assessment criteria above)

The exam has not been passed or the calculated average of the exam tasks is less than 1.

Assessment criteria - satisfactory (1-2) (Not in use, Look at the Assessment criteria above)

The student identifies the key machine parts, joints and transmissions, such as shaft couplings, rivet joints, chain and belt transmissions, in mechanical engineering and power transmission, and is able to dimension them into simple objects under supervision. The student is aware of the importance of standards in selection measurement and is able to form larger entities, for example motor-clutch-gear drive, from the components of his choice under supervision.

Assessment criteria - good (3-4) (Not in use, Look at the Assessment criteria above)

The student is well acquainted with the key machine parts, joints and transmissions, such as shaft couplings, rivet joints, chain and belt transmissions, in mechanical engineering and power transmission, and is able to independently dimension them to conventional objects. The student takes into account the correct standards in the selection dimensioning and is able to form larger entities, for example motor-clutch-gear operation, from the components he has chosen. The student is able to apply what he / she has learned to practical problems and take responsibility for his / her own performance.

Assessment criteria - excellent (5) (Not in use, Look at the Assessment criteria above)

The student knows and understands extensively the key machine parts, joints and transmissions, such as shaft couplings, rivet connections, chain and belt transmissions, in mechanical engineering and power transmission, and is able to suitably dimension them for demanding objects. The student justifiably takes into account the correct standards and different solution options in the selection dimensioning and is able to independently form larger entities, for example motor-clutch-gear drive, from the components of his choice. The student is able to look for different ways of working and solutions, justify his / her choices and try new types of ways of working. Understands the economic and welfare-promoting effects of their activities and is able to act in anticipation of them.
