Every now and then screw drives are used in mobile devices, e.g. in wheel alignment devices, automobiles, stair climbers or medical devices. Weight plays a major role in these applications.
The reduction in weight can be significantly influenced by the choice of materials, for example by using plastic nuts in combination with aluminum spindles.
In some cases, the use of a safety nut / catch nut can also optimize the diameter of the screw drive because the safety factor can be reduced.
There is also the option of subsequently drilling the spindle hollow or rolling the thread onto a pipe.
junaspin will be happy to support you in the selection and design of your screw drive. We are happy to calculate the remaining strength after the weight has been “optimized”. In addition to the technical requirements, economic aspects are of course also relevant here. We can incorporate relevant experience from “real applications” here.
