Abstract [sv]

Möjligheter att reducera vikten på en hydraulmotor, som tillverkas på Parker Hannifin AB i Trollhättan, har studerats. Målet med arbetet var att ge förslag på hur motorn kan göras lättare för att nå det framtida målet att erbjuda kunder en lättviktsmotor (LWM) lämpad som fläktmotor.

För att identifiera komponenterna och deras vikter vägdes alla delar var för sig. Värdena visade att trumhus, lagerhus, axel och lagerpaket stod för ca 75 % av motorns totala vikt. Arbetet koncentrerades därför på att reducera vikten på dessa delar.

Flera koncept togs fram med lägre vikt och bibehållen prestanda. Vissa delar kontrollerades mot hållfasthet med handberäkningar och FEM-analyser. Enligt beräkningarna finns möjlighet att reducera vikten med 45 %.

Om hydraulmotorn konstrueras enligt koncepten, bör det framtida målet kunna nås, till-verkning av en lättviktsmotor som är betydligt lättare än dagens hydraulmotor.

Abstract [en]

The weight reducing possibilities for a hydraulic motor, produced by Parker Hannifin AB in Trollhättan, have been investigated. The goal was to provide suggestions for weight optimization to offer customers a light weight motor (LWM) that is well suited as a fan motor.

The mass of each part was determined and their functions were identified. The result showed that the housings, shaft and bearings represented 75% of the motor’s total mass. The work was thus concentrated to these parts.

Multiple suggestions were generated where weight and performance were taken into consideration. Some parts were analyzed with the aid of FEA-software and hand calculations. The result indicates that a weight reduction of 45% is possible.

If the hydraulic motor is redesigned according to the concepts, the goal of a light weight motor can be achieved.
