A root-end of the blade is connectable to a fixation unit which is pivotably mounted around a first reference-point. A first static moment of the fixation unit without the blade connected is determined in reference to a first reference-point, while the first static-moment is acting on the fixation-unit at the first distance. A second static-moment of the fixation unit and the connected blade is determined at a second distance in reference to the first reference-point, while the second distance is allocated to a cross-section of the blade. The first and the second static-moment are used to calculate the static-moment of the blade.

A lock-on switch system for hand drill comprises: a switch disposed in a switch housing(3) for controlling the operation of the drill; a trigger(2) which is adapted to be movable between a home position where the trigger(2) turns off the switch and a pushed-in position where the trigger(2) turns on the switch; a pivotable locking bar(4) having a front end adapted to be engaged with the trigger(2) for locking the trigger(2) in the pushed-in position; a slidable actuator(7) adapted for pushing the locking bar(4) into engagement with the trigger(2); and biasing means adapted for applying a force on the locking bar(4) in a direction of disengaging the locking bar(4) from the trigger(2).

A controller for a motor vehicle with a carrier plate for receiving a component carrier with a component carrier foot. The carrier plate has a recess through which the component carrier can be passed and which is suitable for receiving the foot, wherein the dimensions of the recess in the region of the component carrier and in the region of the foot in the X / Y-direction correspond to maximum admissible dimensions of the component carrier and of the foot (5) in the X / Y-direction. In the Z-direction, a pressing geometry is arranged on the recess or on the foot such that after establishing a positive-fit or non-positive connection between the carrier plate and a system interface, the pressing geometry or a part that is arranged opposite the pressing geometry is in such a deformed state that the foot is in the recess in a fixed state and without play.

A method for producing an objective lens mount for an objective lens of a camera suitable for use in motor vehicles includes the following method steps: The objective lens mount and a front housing half-shell of the camera are produced as one component in a single working process. The objective lens mount and the front housing shell are made of metal materials or plastic material having glass fiber components. The objective lens mount built in one piece with the front housing shell is adapted to the length of the objective lens by chip-forming machining.

A component system of a turbine engine including a first component segment and a second component segment configurable in a ring segment shape, so that at least one abutment surface of the first component segment and an abutment surface of the second component segment abut against each other; together, the first component segment and the second component segment including at least three overlapping elements for sealing a gap between the abutment surfaces. In the case of mutually abutting abutment surfaces, each overlapping element overlapping radially with the respective other component segment. At least two of the overlapping elements are configured on the first component segment, while at least one of the overlapping elements is configured on the second component segment. In the case of mutually abutting abutment surfaces, the overlapping element of the second component segment is axially configured between the overlapping elements of the first component segment.

A shifting device includes a first shifting element operable to establish a torque-proof, positive-locking connection between a first element and a second element. A second shifting element is operable to establish a torque-proof, positive-locking connection between the second element and a third element. The first element is coupled to the third element such that displacement of the first element by a common actuating element in one of a first and a second displacement direction provides rectified displacement of the third element. The third element is coupled to the first element such that displacement of the third element by the common actuating element in one of the first and second displacement directions provides rectified displacement of the first element. The second element is fixed in position in both the first and second displacement directions. A related transmission is also provided.

A pin for guiding a gear has a substantially cylindrical outer surface section, wherein the outer surface section comprises a substantially cylindrical rolling surface section, which is aligned and formed so as to make possible the guiding of the gear. The outer surface section further has a groove, which is formed so as to accommodate a retaining ring, wherein the groove is disposed with respect to the rolling surface section so as to make possible a guiding, directly or indirectly via the retaining ring, of a rolling-element assembly along the axial direction of the pin. In this way it is possible to provide a guiding of a gear wherein a small tolerance chain is implemented with respect to the axial position.

The invention relates to the field of busbar assembling and welding, in particular to a welding work platform with mobile clamps. The welding work platform with the mobile clamps comprise a frame body, a welding platform and a sliding rail, wherein the welding platform and the sliding rail are arranged on the frame body. The welding platform and the sliding rail are separably arranged. The mobile clamps are arranged on the side, close to the sliding rail, of the welding platform. Compared with the prior art, the multiple mobile clamps are arranged on the welding platform, operators can conveniently adjust the tracks of sliding blocks, and the welding work platform conforms to the human engineering principle in the human arm operation range. The multiple sliding blocks on the mobile clamps are used for conducting one-time positioning on one product, and therefore operation errors caused by multiple times of positioning are reduced, and therefore the dimensional tolerance chain of the product is not affected. The mobile sliding rail and the welding platform are separably distributed, and therefore high-temperature deformation damage, caused by the high temperature of the welding platform, to the sliding rail and the sliding blocks is avoided. A ruler is embedded in the welding platform so that sizing is facilitated, and measuring errors caused by manual measurement are reduced. A welding rod storage box is arranged on the welding platform so that people can obtain welding rods conveniently.
