    • The present invention relates to a rotary motor, preferably a pivot drive for construction machinery, hoisting gear, trucks and the like, comprising an elongate, approximately tubular housing, at least one piston which is axially displaceably received in the housing and which can be axially driven by the charging of a pressure medium in a pressure chamber as well as at least one shaft which is received axially fixedly in the housing and rotatably around an axis of rotation, with the piston having a shaft passage cut-out by which the piston is axially displaceably seated on the shaft. In accordance with the invention, the shaft forms a crankshaft whose axis of rotation is offset with respect to the shaft passage cut-out. The shaft piece respectively passing through the shaft passage cut-out has a lever arm which is opposite the axis of rotation of the shaft and which translates the radial force at the engagement between the shaft and the piston which arises due to the axial displacement of the piston and the pitch of the spiral engagement track between the shaft and piston and/or between the piston and the housing into a rotary movement of the shaft with respect to the housing or vice versa. To achieve favorable force output conditions, provision is in particular made in this respect for the shaft passage cut-out to be arranged approximately centrally in the piston with respect to the cross-sectional surface of the piston, with a security against rotation of the piston being omitted so that a rotatability of the piston with respect to the housing is given.

    • The present invention relates to a rotary motor, preferably a pivot drive for construction machinery, trucks and the like comprising an elongate housing, preferably an approximately tubular housing, a piston displaceably received in the housing, which is axially displaceable by charging with a pressure medium in a pressure chamber, and a shaft received axially fixedly, but rotatably in the housing, with the piston being in screw engagement with the shaft and/or the housing. The invention furthermore relates to a method for the manufacture of such a rotary motor. The present invention departs from the previous approach of separating the sealing of the piston at the shaft and at the housing from the section effecting the rotary guide or the screw engagement. In accordance with the invention, a surface pair of piston and shaft and/or of piston and housing effecting the screw engagement can simultaneously form a sealing surface pair for the sealing of the pressure chamber for the charging of the piston with pressure. The same piston section simultaneously serves the transfer of torque and sealing. A considerably reduced construction length can hereby be achieved since the axial spacing between the sealing section and the rotary guide section or the screw engagement section of the piston is omitted. In addition, the respective components, in particular the housing and the shaft, can be manufactured in an endless manner and be produced as needed and in the required length.
    • 本发明涉及一种旋转电动机,优选地是用于工程机械,卡车等的枢转驱动装置,其包括细长壳体,优选地是近似管状的壳体,可移动地容纳在壳体中的活塞,该活塞可通过用压力介质 在压力室中,并且轴被轴向固定地接收,但是可旋转地安装在壳体中,其中活塞与轴和/或壳体螺纹啮合。 本发明还涉及制造这种旋转电动机的方法。 本发明不同于以前的方法,即将活塞在轴处和壳体处的密封与实现旋转导向件或螺钉接合的部分分离。 根据本发明,实现螺钉接合的活塞和轴和/或活塞和壳体的表面对可以同时形成用于密封压力室的密封表面对,用于在压力下对活塞进行充气。 相同的活塞部分同时用于传递扭矩和密封。 由于省略了密封部和旋转引导部或活塞的螺钉接合部之间的轴向间隔,所以可以实现显着减小的结构长度。 此外,相应的部件,特别是壳体和轴可以以环形方式制造,并且根据需要和所需的长度被制造。
