Definitions
- the invention relates to a transmission according to the preamble of claim 1.
- Gearboxes for tunnel boring machines must have a holding brake integrated into the gearbox. In order to realize a corresponding functionality, additional components are required. This causes additional costs and increases the space requirement of the transmission.
- gearboxes of tunnel boring machines are exposed to heavy impacts during operation. These can lead to an overload of the torque transmitting gear components.
- the known from the prior art gearbox offer no protection against overload. To avoid that gear parts are destroyed as a result of shocks, they must be sized larger.
- the planetary stage is provided with a clutch and a brake.
- the brake acts on a ring gear of the planetary stage.
- the ring gear can be rotatably connected to a sun gear planetary stage.
- the planetary stage is blocked.
- the planetary stage can be engaged by opening the clutch and closing the brake. Due to space constraints, however, the minimum orbital ratio of the planetary stage is greater than 3. Small gear steps can not be realized thereby.
- the object of the invention is to make available a transmission, in particular a transmission for a tunnel boring machine, which does not have the disadvantages inherent in the solutions known from the prior art. In particular, the transmission should be inexpensive and robust while maintaining the given space.
- the transmission has a first planetary stage, a second planetary stage, a first brake and a second brake.
- a brake is a switching element.
- Such a switching element is designed to connect two components rotatable relative to each other selectively operable rotatably with each other.
- the switching element has a closed and an open state. In the open state, the components are rotatable relative to each other. If the switching element is in the closed state, it rotatably connects the components with each other.
- the switching element is selectively actuated. This means that the switching element can be converted at any time by actuation from the open state to the closed state and from the closed state to the open state.
- a brake is characterized in that one of the two components, which are rotatably connected by the brake, is arranged rotationally fixed relative to a stationary structure.
- the stationary structure may in particular be a transmission housing.
- the first brake and the second brake can each be designed as a form-locking switching element, for example as a dog clutch, or as a non-positive switching element.
- a form-locking switching element for example as a dog clutch, or as a non-positive switching element.
- positive switching elements With positive switching elements, the described rotationally fixed connection by a positive connection between the components to be connected. Accordingly, a non-positive rotational connection between these components is produced in a non-positive switching element.
- a planetary stage is defined as an arrangement with a ring gear, a planet carrier, one or more rotatably mounted in the planet carrier planetary gears and a sun gear.
- the planetary gears are arranged so that they each mesh with the sun gear and / or the ring gear.
- the ring gear is rotatably mounted.
- the planet carrier and the sun gears of the two planetary stages are rotatably mounted.
- the rotatable mounting takes place in a stationary structure, such as in the transmission housing.
- the sun gear of the first planetary gear and the sun gear of the second planetary gear are rotatably connected. Furthermore, the planet carrier of the first planetary stage and the ring gear of the second planetary stage are rotatably connected to each other.
- the first brake acts on the first ring gear, the second brake on the second ring gear.
- the first brake is designed to produce in the closed state, a rotationally fixed connection between the first ring gear and a stationary structure, such as the transmission housing.
- the second brake is designed to produce a rotationally fixed connection between the second ring gear and the stationary structure in the closed state.
- first brake and the second brake By selectively closing the first brake and opening the second brake or opening the first brake and closing the second brake, two gear stages with different gear ratios can be realized.
- the arrangement according to the invention enables particularly small gear jumps possible.
- the first brake and the second brake can be further configured so that the brakes slip at impact loads. In this way load peaks are filtered out.
- the first brake and the second brake are simultaneously closable, i. can be converted into the closed state. If the first brake and the second brake are closed at the same time, there is at the same time a rotationally fixed connection between the first ring gear and the stationary structure and between the second ring gear and the stationary structure. As a result, the first planetary stage and the second planetary stage are locked to the stationary structure. Thus, the function of a holding brake can be realized without additional components.
- An input shaft of the transmission i. a shaft via which an input torque to be transmitted to an output shaft of the transmission is introduced into the transmission, is preferably non-rotatably connected to the sun gear of the first planetary stage.
- the sun gear of the first planetary stage is driven via the input shaft.
- the input shaft may be integrally connected to the sun gear of the first planetary stage.
- the transmission has a third planetary stage with a rotationally fixed, i. rotatably fixed in a stationary structure ring gear, a rotatably mounted planet carrier, one or more rotatably mounted in the planet carrier planet gears and a rotatably mounted sun gear.
- the planet carrier of the second planetary stage is rotatably connected to the sun gear of the third planetary stage.
- the transmission preferably has a fourth planetary stage with a rotationally fixed, ie rotatably fixed in the stationary structure ring gear, a rotatably mounted planet carrier, one or more rotatably mounted in the planet carrier planetary gears and a rotatably mounted sun gear.
- the planet carrier of the third planetary stage is rotatably connected to the sun gear of the fourth planetary stage.
- the output shaft of the transmission is rotatably connected in a preferred development with the planet carrier of the fourth stage.
- the planet carrier of the fourth planetary stage and the output shaft can be integrally connected to each other.
- the transmission according to the invention or a further development of this transmission are particularly suitable for use in a tunnel boring machine.
- a tunnel boring machine preferably has, in addition to at least one motor, a transmission developed further with an input shaft.
- a rotor of the motor is rotatably connected to the input shaft.
- the engine drives the input shaft.
- the tunnel boring machine on a drill head which is preferably non-rotatably connected to an output shaft of the transmission.
- An inventive method provides that the transmission according to the invention or a development of this transmission is blocked, in which the first brake and the second brake are closed simultaneously.
- the blocking of the transmission is synonymous with a rotationally fixed fixation of at least the output shaft.
- both the output shaft and the input shaft are fixed in a rotationally fixed manner by closing the first brake and the second brake.
- FIG. Matching reference numbers identify identical or functionally identical characteristics. In detail shows:
- Fig. 1 shows a transmission for a tunnel boring machine.
- the transmission illustrated in FIG. 1 has a first planetary stage 101, a second planetary stage 103, a third planetary stage 105 and a fourth planetary stage 107.
- a sun gear 109 of the first planetary stage 101 is rotatably connected to an input shaft 111.
- the input shaft 111 in turn is driven by a motor 113.
- the first planetary stage 101 planetary gears 113, a rotatably mounted planet carrier 115 and a rotatably mounted ring gear 117.
- the planetary gears 113 of the first planetary stage 109 are rotatably supported in the planet carrier 113 and mesh with the sun gear 109 and the ring gear 117 of the first planetary stage 101, respectively.
- the planet carrier 115 of the first planetary stage 101 is rotatably connected to a rotatably mounted ring gear 119 of the second planetary stage 103.
- the second planetary gear 103 has a rotatably mounted sun gear 121, a rotatable planet carrier 125 and rotatably mounted in the planet carrier 125 planet gears 127.
- the planet gears 127 of the second planetary stage 103 mesh with the ring gear 119 and the sun gear 121 of the second planetary stage 103, respectively.
- the sun gear 129 of the third planetary stage 105 is rotatably supported just like a planetary carrier 131 of the third planetary stage 105.
- a ring gear 133 of the third planetary stage 105 is rotatably fixed in a gear housing 135.
- Planetary gears 137 of the third planetary stage 105 are rotatably supported in the planet carrier 131 of the third planetary stage 105 and mesh with the sun gear 129 and the ring gear 133 of the third planetary stage 105, respectively.
- the fourth planetary stage 107 is constructed analogously to the third planetary stage 105 and has, in addition to the sun gear 139 a rotatably mounted planet gears 141 and a rotationally fixed in the gear housing 135 fixed ring gear 143.
- Planetary gears 145 of the fourth planetary stage 107 are rotatably mounted in the planet carrier.
- An output shaft 147 is rotatably connected to the planet carrier 141 of the fourth planetary stage 107. Via the output shaft 147, a drill head of the tunnel boring machine is driven.
- first brake 149 and a second brake 151 By means of a first brake 149 and a second brake 151, two gears can be switched.
- the gears are characterized by different ratios between the input shaft 111 and the output shaft 147.
- first brake 149 and / or the second brake 151 By selectively closing the first brake 149 and / or the second brake 151, two different transmission ratios between the input shaft 111 and the output shaft 147 can be realized accordingly.
- a first gear or a first gear ratio between the input shaft 111 and the output shaft 147 comes about by closing the first brake 149 and opening the second brake 151.
- the first brake 149 acts on the ring gear 117 of the first planetary stage 101.
