Development of heat element at Husqvarna AB 2019 : Development of heat element for the handle on petrol driven chain saws. (English)
Abstract [en]

Throughout Jönköpings University has a bachelor thesis at Husqvarna AB been done, were the main focus is to develop the existing heating element. On the existing front and rear handle is where the heating element are placed and the material the handles are made of is aluminum respectively plastic. These handle are also called the reference at Husqvarna AB.

 

To be able to have different type of concepts was a method called concept generating, where these concepts were developed and later on eliminate nonrealistic ideas. During the project there was a lot of visits at several companies to be able to see the production and have a meeting with them. PTC-technology was the chosen heating element for this project and stands for “Positive Temperature Coefficient” and is a self-regulating heating element. PTC has a low inner resistance until it reaches the temperature that it is manufactured for to maintain a more stable heating level. Tests were made on the concepts that was given against the reference to see which concept that is most suitable for further development. Different methods and theories was used to be able to create tools for embossing the front handle, which later on got heat-treated.

 

The existing heating element is based on the amount of rounds per minute the flywheel rotates which result in different heating levels for the consumer. PTC technology gives a more stable heating level for such system with various rotational speed. Husqvarna AB’s purpose with this thesis is to develop a more stable heating element on the XPG chainsaws.

 

This thesis ended with a result of two different winning concepts which was given recommendations for how they could further be developed to be possible to replace the existing heating element.
