The invention relates to a control cam set with a working cam and a recoil cam, in which no bending moment is generated and in which the working roller and the recoil roller can roll with no play.
This minimum bending yield strength is greater than the bending moment resulting from the combined frictional resistance forces acting on the post.
The weighing device has a bending beam (20, 31, 41) from which bending moment transmission means (35, 36, 42, 43) extend laterally.
This bending moment, which results in a slight deformation of the shaft or the entire holding fixture (1), is used to correct the true running.
It narrows in accordance with the bending moment curve towards the ends (7) of the sheet-steel strip (4).
The advantage of the invention lies in that the introduction of the nozzle clamping force into the injection unit (2) is devoid of moment of flexure.
The linear actuator has the advantages of a reduction in bending torque, a decrease in the wear of the sliding block, and an increase in service life.
The invention pertains to a tool or pliers for effecting a torque bends or twists to orthodontic rectangular arch wire.
The drive shaft of very small size (1/3 of the conventional drive shaft) decrease twists and longitudinal bending couple reducing vibrations of 2nd level.
They can therefore have a smaller cross-section, reducing the weight thereof.
