摘要： An electro-mechanical actuator for generating an axial actuation force is provided. The electro-mechanical actuator includes an electric machine having a stator (1) and a rotor (2). The electro-mechanical actuator also includes a spindle drive with a rotary element (6) and with an element that is movable in a translatory manner. A rotation of the rotary element (6) may result in a translatory motion of the element that is movable in a translatory manner. The rotor (2) and the rotary element (6) of the spindle drive are coupled to each other in a circumferential direction (U) such that a rotation of the rotor (2) results in a rotation of the rotary element (6) of the spindle drive (5). A rotational play (8) is formed between the rotor (2) and the rotary element (6) of the spindle drive in the circumferential direction (U).

摘要： A linear actuator assembling method includes a semi-finished product assembling step and a threaded shaft assembling step. The semi-finished product assembling step is to form a semi-finished product, and the semi-finished product includes a case, a main gear, and a main gear bearing. The main gear and the main gear bearing are surrounded and restricted by the case, and the main gear bearing is sleeved on the main gear. In the threaded shaft assembling step, a threaded shaft is reversely assembled, and one end of the threaded shaft is inserted into the main gear to allow the end of the threaded shaft to be restricted by the main gear.

摘要： A combined apparatus for heating, cooking, grilling and defrosting of foods of various kinds, depending on the type of foods to be treated from time to time and the duration of the foods treatment foreseen by each user of the same apparatus, where each hot treatment of foods may be effected either by heating or by microwaves only, or by heating and microwaves combined to each other. There are described in detail all the technical characteristics of the apparatus and the relative control circuits either for heating or for generating the microwaves. Advantages include use of a sole and single apparatus for hot treating the foods for providing for the heating, the cooking, the grilling and the defrosting of the same foods, instead of employing as it happens hitherto of single separated apparatuses for performing the same functions.

摘要： An adjustment mechanism for a seat comprises at least one screw shaft (111, 112) and a motor for driving the at least one screw shaft (111, 112). Further, the adjustment mechanism comprises at least one nut element (121, 122) engaged with the at least one screw shaft (121, 122) in such a way that a rotation of the at least one screw shaft (111, 112) caused by the motor translates into a linear motion of the at least one nut element (121, 122). In a first range of the linear motion of the at least one nut element (121, 122) the linear motion translates into adjustment of the seat according to a first degree of freedom, and in a second range of the linear motion of the at least one nut element (121, 122) the linear motion translates into adjustment of the seat according to a second degree of freedom.

摘要： The present disclosure relates to a hollow-type BLDC motor of a power sliding device of a vehicle seat, and a nut coupled to a lead screw is injection-molded with a plastic and installed only on a longitudinal partial section of the inner diameter of a rotor, a magnet of the rotor is produced in an integrated cylindrical shape having no gap between magnetic poles, and a skew angle is given on a boundary line between the magnetic poles, thereby reducing noise and vibration.

摘要： A linear electric actuator system, preferably for patient lifters, comprising at least one linear electric actuator and a controller having a power limiting circuit for limiting the power to the at least one linear electric actuator. The actuator system is arranged such that the threshold value of the maximum permissible power in the power limiting circuit may be changed, and that this change may be performed via reference to the position of the spindle nut on the spindle as a look up in a table showing a corresponding value for the power limit.

摘要： Machining tool comprising a frame in which a drive shaft for a tool is mounted so as to pivot about a rotation axis and to move axially along the rotation axis. The shaft is connected to two rotary motors, namely a first motor connected to a member for meshing with a fluted portion of the shaft in order to drive the shaft in rotation and a second motor connected to a nut engaged with a threaded portion of the shaft in order to move the shaft axially. The motors are connected to at least one control unit designed to control the motors independently of one another, and the first motor and the second motor are coaxial with one another.

摘要： In a screw device where a shim is disposed between two nuts, a screw device that can detect preload is provided. The preload detectable screw device includes: two nuts; a shim sandwiched and compressed between the two nuts; a coupling portion configured to couple the two nuts in such a manner as to be incapable of relative rotation to each other; and a force sensor for detecting preload. A contact surface of at least one of the two nuts with the shim is provided with a recess, spaced apart from the coupling portion, in such a manner as to reduce the contact area. The force sensor is attached near the recess on an outer surface of the shim.
