Definitions

  • the invention relates to a hoist with a motor and a transmission existing drive unit, one that can be driven by the drive unit Drive shaft with an attachable drive flange and one with the Drive flange connectable cable drum, the torque of the Drive shaft is transferable to the cable drum via a coupling.
  • Hoists designed as cables have an essentially cylindrical one Rope drum, which is rotatably mounted in a frame.
  • the rope drum comes with Driven by a gear motor, the output shaft of the gear is rotatably coupled to the cable drum.
  • Manufacturing tolerances and Misalignment usually with a so-called "3-point bearing" compensate equipped rope drum, which lead to tension in the drive can, it is known from practice, between the output shaft and the To arrange a cable drum a clutch that absorb these misalignments can.
  • the coupling is a tooth coupling formed, the a pinion and non-rotatably connected to the output shaft one meshing with this pinion on the drive flange of the cable drum set sprocket includes.
  • TGL coupling in which a non-rotatable on the Output shaft fixed flange via one or more drive pins in Recesses engages an end wall of the cable drum.
  • DE 298 16 675 U1 discloses a coupling for hoists for transmitting the Moment of a driven gear shaft on a rope drum, with one on one end of the gear shaft arranged clutch hub and with an over inner and outer covers closed, arranged on the coupling hub Clutch housing.
  • the clutch housing and the clutch hub are on Coupling housing and circular toothing formed on the coupling hub positively connected with each other and in the two circular gears Drilled holes are arranged barrel rollers for power transmission.
  • the invention is based on the object of a hoist equipped with a clutch that is simple and Space-saving construction of a coupling that compensates for misalignment Cable drum guaranteed with the drive shaft.
  • the inventive design of the clutch as between the Components to be coupled with one another in a form-fitting manner and thus torque To be arranged to transmit coupling element, it is possible to use the coupling simply constructed and inexpensive to design.
  • the torque transmission of the components to be coupled with one another takes place in accordance with a practical embodiment of the invention in that the Coupling element pointing radially outwards and inwards on both sides Has driving cams, each for torque transmission in corresponding recesses of the two adjacent, can be coupled together Intervene components.
  • That which forms the coupling is at least one Coupling element made up of individual coupling segments.
  • the Construction from individual coupling segments enables in a simple manner the compensation of manufacturing tolerances.
  • the coupling segments preferably point for the extension between the Drive flange and the cable drum are flat from the driving cams extending sections forming sections. It is therefore possible to Rope drum over the sections of the coupling segments on the drive flange to store.
  • the individual extend Coupling segments on both sides around the driving cams, d. H. in Circumferential direction of the drive flange.
  • the individual coupling segments advantageously extend in the shape of a circular arc between the drive flange and the cable drum.
  • the coupling element finally made up of individual spaced apart Coupling segments built up.
  • each coupling segment has radially outward-facing driving cams on both sides has, each for torque transmission in corresponding recesses of the two adjacent components that can be coupled together.
  • the driving cams are advantageously direct to one another facing radially outwards and inwards on the Coupling segments arranged.
  • the Driving cams at least partially made of a harder material than the rest of the Coupling element exist and preferably a shear-resistant core include.
  • the invention proposes that the at least one Coupling element at least partially made of an elastic material, in particular a plastic material.
  • the elasticity of the material enables an additional compensation of possible tensions, whereby by a appropriate material selection additional damping properties can be achieved are to reduce an impact load from the cable to the drive shaft.
  • FIG. 1 shows schematically the structure of a cable trained hoist.
  • the hoist essentially consists of one Engine and a transmission existing drive unit 1, one of the Drive unit 1 drivable drive shaft 2 with attachable Drive flange 3 and a non-rotatably connectable to the drive flange 3 Rope drum 4, onto or from which a rope 5, only indicated schematically can be wound up or unwound.
  • the cable drum 4 has a So-called "3-point storage” equipped, in which the cable drum 4 over two Bearings 6a, 6b on the side of the drive shaft 2 and via a bearing 7 on the one side the drive shaft 2 opposite drum pin 8 is mounted.
  • FIG. 3 also shows that each coupling segment 9a of the Coupling element 9 pointing radially outwards and inwards on both sides Carrying cam 10, which for transmitting the torque in corresponding recesses 11 of the drive flange 3 and the cable drum 4 intervention.
  • the driving cams are 10 always directly opposite each other radially outwards and inwards arranged on the coupling segments 9a.
  • the driving cam 10 of the two sides of a coupling segment 9a staggered to be arranged on a coupling segment 9a.
  • the coupling elements 9a extend in the shape of a circular arc in the intermediate space between the drive shaft 3 and the cable drum 4, whereby they are around on both sides widen the driving cams 10 around in the circumferential direction To form contact surfaces 9b forming sections 9c on which the cable drum 4th rests.
  • FIGs 5a to 5c finally show three embodiments Formation of the built up from individual coupling segments 9a Coupling elements 9.
  • the coupling element 9 quasi integrally formed, the individual Coupling segments 9a to one another via elastic connecting webs 12 are connected.
  • each coupling segment has 9a molded projections 13 and formed corresponding to the projections 13 Recordings 14 on which individual coupling segments 9a can be coupled to one another are.
  • a latching coupling represents, the projections 13 and receptacles 14, for example be rectangular, so that it does not lock, but only in interlock essentially.
  • the coupling element 9 of the third embodiment shown in Figure 5c consists of individual spaced apart Coupling segments 9a. These three variants show one Length compensation between the individual driving cams 10 and corresponding recordings 11 and thereby a uniform distribution of Rope pull force S on the individual coupling segments 9a.
  • the driving cams 10 include one for this purpose shear-resistant core 10a, which can be made of metal, for example; the remaining coupling segment 9a is then made of plastic. Basically, it is also possible to cast metals, such as Bronze alloys to be used for the coupling elements 9.
  • the Shear-resistant core 10a can then be omitted.
  • shear-resistant cores 10a have the task of failing the Driving cams 10 - approximately through abrasion - a safe torque transmission to ensure between the coupled components until the defective Coupling element 9 or coupling segment 9a is exchanged.
  • a due to this formation gap 15 is particularly the picture Figure 2a can be seen, while Figure 4 shows the design of a Longitudinal groove 11 a shows.
  • Figures 2a and 2b show how an angular offset between the Longitudinal axes of the cable drum 4 and the drive flange 3 and / or the Drive shaft 2 can be compensated.
  • a contact surface 9b of the coupling element 9 on a contact surface 3a of the coupling drive flange 3 convexly curved outwards.
  • the convex curvature is on the contact surface 3a of the drive flange 3 is formed.
  • the corresponding convex curvatures of the contact surfaces are shown in Figures 2a and 2b marked with the crown radius R.
  • a coupling designed in this way is characterized in that it is simply constructed and with a small size a good compensation Manufacturing and installation tolerances enabled.
