<p>This degree project was conducted in collaboration with Gremo AB located in Ätran.</p><p>The aim of the project was to develop a solution to secure quality and to help assembling</p><p>the locknut holding the vertical hinge on the harvesters and foresters from Gremo.</p><p>At this time the nut is assembled manually by the aid of an overhead crane. The nut is</p><p>tightened differently from time to time, and there was no specified torque to which it is</p><p>tightened. Another present problem was the locking washer which sometimes gets</p><p>damaged during assembly, when this happens the procedure has to be started over from</p><p>the beginning. The current assembly procedure is very time consuming and lengthy for</p><p>the employees.</p><p>Our task was to design a machine that could tighten the nut to a specified torque with a</p><p>margin of error of ± 3%. The assembly procedure will be held simple and the time</p><p>required at a minimum.</p><p>The project started by developing several principle solutions, the one solution that best</p><p>matched our specifications were developed to a primary solution.</p><p>Today we have started manufacturing and assembling our prototype. Our goal is that the</p><p>equipment will be taken into use by Gremo.</p>
