Definitions

  • the invention relates to a transmission according to the preamble of claim 1.
  • gearboxes known from the prior art have eyelets which are cast into the gearbox housing.
  • the eyelets can either be attached directly to a crane hook or hooks can be screwed into the eyelets.
  • Such solutions are disadvantageous because they complicate the casting of the transmission housing and make them correspondingly expensive.
  • the invention is based on the object of making available a transmission which does not have the disadvantages inherent in the solutions known from the prior art.
  • the manufacture of a transmission which has devices for handling by means of a crane is to be simplified.
  • the gearbox has a housing. This is provided with a first and a second hole.
  • the first hole has a first mouth, the second hole accordingly a second mouth.
  • the first hole and the second hole preferably each have exactly one mouth.
  • the first hole and the second hole are preferably cylindrical.
  • the first hole and the second hole are holes before pulling.
  • a hole is a hole made by drilling or a hole that is made differently but has the same shape. Accordingly, a hole is a hole with the basic shape of a straight circular cylinder.
  • the first mouth and the second mouth are outside the housing.
  • the housing encloses a cavity - the inside of the housing. It encapsulates the inside in relation to the surrounding space.
  • the first hole opens with the first mouth, the second hole with the second mouth in the surrounding space.
  • a rod or a rod is provided which engages through the first mouth in the first hole and through the second mouth in the second hole. Since the first mouth and the second mouth are outside the housing, the rod is also outside the housing.
  • the gear can be attached to a crane hook using the rod. Both the rod and the two holes are comparatively simple and inexpensive to manufacture.
  • the housing is made at least in two pieces, ie has a first piece and a second piece.
  • the first piece and the second piece are not connected to one another in one piece. These are pieces that are physically separate from each other.
  • the first piece has the first hole, the second piece the second hole.
  • the rod When assembling the housing, the rod is inserted into the first hole or the second hole before the pieces of the housing are joined together. When joining, the rod is inserted into the remaining hole. The rod is then positively fixed in the first hole and in the second hole.
  • the transmission is preferably developed with a ring gear.
  • This is part of a planetary stage, which also has a planet carrier, planet gears and a sun gear.
  • the planet gears are rotatably mounted in the planet carrier and mesh with the ring gear and / or the sun gear.
  • a ring gear forms a third piece of the housing.
  • the ring gear is arranged between the first piece and the second piece and connects the two pieces accordingly.
  • the joint between the first piece and the second piece comes about via the ring gear.
  • the ring gear is joined on the one hand to the first piece and on the other hand to the second piece. Since the first piece has the first hole and the second piece has the second hole, the rod spans the ring gear.
  • a gap or space runs between the two mouths of the holes.
  • the mouths are spaced accordingly. If the ring gear in accordance with further training is present, the ring gear is located in the intermediate space. The space enables a means for attaching the gear, such as a crane hook or a rope, to be inserted and fastened to the rod.
  • the orifices are preferably further developed such that they are directed towards one another.
  • the holes can be aligned.
  • the rod has three sections.
  • the sections are arranged along the rod and separated from one another by cross-sectional areas.
  • a first section engages in the first hole, a second section in the second hole.
  • the third section runs between the first section and the second section and connects these sections to one another.
  • first section and the second section each engage in one of the holes, these sections are preferably cylindrical.
  • the first section and the second section thus have the shape of a straight cylinder, preferably a straight cylinder.
  • the third section can be straight or curved.
  • a curved Ver course in which a center line of the third section describes the course of a curved curve, creates space for introducing the means for attaching the gearbox bes.
  • a straight course of the third section, in which the third section and consequently the entire rod are cylindrical, enables the rod to be Move house.
  • the first hole and the second hole are preferably continuous. By moving the rod, the rod can be threaded into a closed loop.
  • FIG. 1 shows a gear housing with a suspension device.
  • FIG. 2 shows a curved suspension device.
  • the transmission housing 101 shown in FIG. 1 has a first housing shell 103 and a second housing shell 105.
  • a Flohlrad 107 is also part of the hous 101.
  • the Flohlrad 107 is located between the first housing shell 103 and the second housing shell 105.
  • the two housing shells 103, 105 each have an outwardly protruding bulge 109.
  • the Flohlrad 107 runs axially between the bulges 109. Both bulges 109 are each provided with an axially extending Boh tion.
  • a rod 11 1 engages in the bores. This is used to attach the housing 101 to a crane.
  • Fig. 2 shows a rod 201 with a bent portion 203.
  • the bent portion 203 connects two straight portions 205 together.
  • the straight sections 205 are designed to engage in the bores of the bulges 109.
  • the curved section 203 provides more space for a crane hook.
  • the bending load on the rod 201 is reduced when the gear is attached to the crane.

Abstract

L'invention concerne une transmission pourvue d'un carter (101), le carter (101) présentant un premier trou pourvu d'une première embouchure et un deuxième trou pourvu d'une deuxième embouchure, et la première embouchure et la deuxième embouchure se trouvant à l'extérieur du carter (101). La transmission présente une barre (111, 201), qui s'insère par la première embouchure dans le premier trou et par la deuxième embouchure dans le deuxième trou.
