Solution
In the machine design,
linear bearing systems from the drylin modular product system were used, which allow highly robust, clean, lubrication-free, efficient and simple movements in all system parts that require movement. Their low coefficient of friction increases the service life of the devices and minimises maintenance requirements:
The torque transmission from the stepper motor to the compression system of the implants was realised with drylin SD lead screw drives (screw and nut). Another set of drylin SD lead screw drives was used in the same equipment for torque transmission from the gearbox to the mechanical bending system, which enables testing in the vertical direction. Two sets of
drylin T profile rail guides with a linear guide and two carriages were used to guide the bending system horizontally. To guide the movable stem, in which the plates compressing the implants are fixed, a set of
drylin T profile rail guides with a linear guide and four carriages were used to enable cyclical and abrupt movement over the implants in accordance with the standard.
