Description
Technical field
This utility model relates to miniature shield machine technical field, particularly relates to a kind of main driving for miniature shield machine.
Background technology
The driving bearing commonly used in the main driving of current shield machine has external tooth type and internal-gear type, no matter but interior (or outer) tooth-like driving bearing, the common feature of the two is driving bearing is integral type structure with transmission gear ring；Wherein, the radial dimension of external tooth type driving bearing is big so that installs the main driving body after external tooth type driving bearing and amasss excessive, and after causing installing this main driving in the installing space of miniature shield machine, people storehouse is just fitted without space；And about internal-gear type driving bearing, after installing reductor and motor, the installing space being originally used for installing center steering body is just occupied, cause that center steering body cannot be arranged in main driving.But miniature shield machine to be mainly characterized by radial dimension little, its internal installing space is extremely limited, this limited installing space not only needs to install main driving, also have and other parts are installed, but above reason all can cause that the main driving commonly used in current shield machine can not be used in miniature shield machine, indirectly increases manufacturing cost.
Summary of the invention
The technical problems to be solved in the utility model is in that, for drawbacks described above of the prior art, there is provided a kind of compact conformation, external diameter little and the main driving for miniature shield machine that internal diameter is big, this main driving being used for miniature shield machine can meet the requirement that miniature shield machine radial dimension is little, leaves sufficiently large space for the parts being arranged on the dividing plate of soil storehouse with the center steering body being arranged on centre.
This utility model is for solving above-mentioned technical problem, and its technical scheme adopted is as follows:
A kind of main driving for miniature shield machine, including the casing being connected with shield body, and casing one end open, and the internal cavity of casing is provided with three-row roller bearing, the cutter plate driver little gear of input, cutter plate driver external toothing, reductor and connector；
Cutter plate driver inputs little gear and is connected with speed reducer drive, and cutter plate driver inputs little gear and engages with cutter plate driver external toothing；
The front end of connector is connected with the cutterhead separately set and three-row roller bearing, and the rear end of connector is connected with cutter plate driver external toothing.
Described in the utility model for, in the main driving in miniature shield machine, the internal cavity of casing being provided with three-row roller bearing, the cutter plate driver little gear of input, cutter plate driver external toothing, reductor and connector；Wherein, cutter plate driver inputs little gear and is connected with speed reducer drive, and cutter plate driver inputs little gear and engages with cutter plate driver external toothing；The front end of connector is connected with the cutterhead separately set and three-row roller bearing, and the rear end of connector is connected with cutter plate driver external toothing, it can thus be appreciated that, compared with prior art, structure for the main driving in miniature shield machine described in the utility model is extremely compact, and owing to cutter plate driver external toothing and three-row roller bearing are two independent parts, non-Unitary designs, compared with prior art, such design makes described in the utility model to also ensure that relatively larger internal diameter when external diameter is little for the main driving in miniature shield machine, make described in the utility model to disclosure satisfy that, for the main driving in miniature shield machine, the requirement that miniature shield machine radial dimension is little, parts for being arranged on the dividing plate of soil storehouse leave sufficiently large space with the center steering body being arranged on centre；For cutter plate driver external toothing and three-row roller bearing, user can select different suppliers as required, so advantageously reduces the manufacturing cost for the main driving in miniature shield machine described in the utility model.
In addition, in technical scheme described in the utility model, the bearing adopted is three-row roller bearing, what this three-row roller bearing was only subjected to that cutterhead is delivered to himself axially promotes mainly pressure, tilting moment and propulsive thrust load, and the driving torque that cutterhead rotates is born by above-mentioned cutter plate driver external toothing, it can thus be appreciated that, compared with prior art, adopt three-row roller bearing and cutter plate driver external toothing to improve the carrying condition of three-row roller bearing, contribute to extending the service life of three-row roller bearing.
As a kind of improvement to the main driving for miniature shield machine described in the utility model, the outer ring of above-mentioned three-row roller bearing is connected with casing by the first bolt.Adopt the first bolt the outer ring of three-row roller bearing and casing to be detachably connected, on the one hand, to serve the effect of fixing three-row roller bearing and casing, on the other hand, also facilitate and three-row roller bearing is safeguarded.
As a kind of improvement to the main driving for miniature shield machine described in the utility model, the front end of above-mentioned connector, the inner ring of three-row roller bearing and casing are sequentially connected with by the second bolt.The second bolt is adopted the front end of connector, the inner ring of three-row roller bearing and casing to be detachably connected successively, same as above, on the one hand, to serve the effect of fixing three-row roller bearing and connector and casing, on the other hand, also it is beneficial to three-row roller bearing is safeguarded.
As a kind of improvement to the main driving for miniature shield machine described in the utility model, above-mentioned connector is circular connector.
As a kind of improvement to the main driving for miniature shield machine described in the utility model, above-mentioned reductor is planet-gear speed reducer.Reductor is chosen as the volume that planet-gear speed reducer contributes to reducing the main driving of miniature shield machine described in the utility model so that its structure is more compact, and its bearing capacity is big, stable working.
It addition, in technical scheme described in the utility model, all it is not specifically noted, all can by adopting the conventional means in this area to realize.
Therefore, the compact conformation of the main driving for miniature shield machine that this utility model provides, and there is the advantage that external diameter is little, internal diameter is big, meeting the requirement that miniature shield machine radial dimension is little, also the parts for being arranged on the dividing plate of soil storehouse leave sufficiently large space with the center steering body being arranged on centre.
