Description
Technical field:
The utility model relates to planet machinery, is specifically related to displacement configuration on the main driving speed reducer of shield machine.
Background technique:
21 century is city to the epoch that are aerial and underground stereo Space Expanding, and world all attaches great importance to Urban Underground railway, the end wears the underground engineering constructions such as rivers tunnel.China's urban population is intensive, builds subway on a large scale in central city, is the fundamental way that each city traffic of solution blocks up.
As TBM, the shield machine of urban subway tunnel, highway, railway construction medium-and-large-sized no-dig technique cubic metre of earth and stone equipment, main driving retarder is wherein its key transmission part.And before this, only have Japan and American-European minority developed country to possess the production technology of this type of retarder.China's dependence on import always in the last thirty years, seriously constrains subway, highway, the cost of Concerning Railway Tunnel Construction and paces.
Along with the development of tunnel, subway etc., shield machine industry is constantly develop rapidly also, and the main driving speed reducer of shield machine obtains more and more application, and what this speed reducer adopted is Planetary Gear Transmission.It is little that Planetary Gear Transmission has volume with it, lightweight, and gear range is large, and the advantages such as efficiency height and stable working obtain to be used widely.
Three grades of positions of this speed reducer are all mounted in the cutterhead frame of shield machine, and the fluid of three level positions cannot be released, and the size at three grades of positions is maximum, when speed reducer horizontal positioned, this position is also minimum.The oil extraction of former import speed reducer is all in a secondary gear ring position, and the oil of such three grades of extreme lower positions cannot be released at all.If waste oil can not be discharged in time, the metal particle contained in waste oil will cause very large impact to retarder.
A, first metal particle destroys oil film, makes tooth face agglutination serious, seriously reduces service life of gear.
B, metal particle increase the kinematical viscosity that will reduce lubricant oil gradually, lubricating oil flow is deteriorated, and gear or the temperature rise of bearing local friction will be very serious; And high temperature can cause gear, the parts such as bearing produce thermal distortion stress, thus have impact on reliability and the efficiency of planetary reducer transmission.
Model utility content:
Technical problem to be solved in the utility model is the defect overcoming prior art, provides new technological design, by the main driving speed reducer of shield machine that the fluid of three grades is discharged.
Technical problem to be solved in the utility model realizes by the following technical solutions.
Displacement configuration on the main driving speed reducer of shield machine, comprise body fuselage, be provided with first level transmission device and secondary transmission device in body fuselage, bottom body fuselage, be provided with oil drain out, in body fuselage, be provided with cavity, three gear stages are provided with in cavity, it is characterized in that: described cavity is provided with drain oil, the Kong Luwei 15 ° of drain oil tilts down, and drain oil hole wall is covered with stair-step, stair-step along the aperture of drain oil to hole in constantly rise, drain oil is provided with plug screw.
The utility model structure is simple, reasonable in design, the oil of three grades of extreme lower positions can be discharged in time by drain oil, avoids the metal particle in waste oil to destroy the flank of tooth, extends service life of gear.Strengthen reliability and the efficiency of planetary reducer transmission.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
Displacement configuration on the main driving speed reducer of shield machine as shown in Figure 1, comprise body fuselage 1, first level transmission device 2 and secondary transmission device 3 is provided with in body fuselage, oil drain out 4 is provided with bottom body fuselage, cavity 5 is provided with in body fuselage, three gear stages 6 are provided with in cavity, wherein cavity is provided with drain oil 7, the Kong Luwei 15 ° of drain oil tilts down, drain oil hole wall is covered with stair-step 8, stair-step along the aperture of drain oil to hole in constantly rise, drain oil is provided with plug screw 9.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
