Abstract
The invention relates to a presetting safety device for an input spline of a main drive speed reducer of a shield machine, which relates to the technical field of engineering machinery. The presetting safety device for the input spline of the main drive speed reducer of the shield machine comprises an input motor for driving the speed reducer; a spline sleeve is connected to the output end of the input motor; a primary sun wheel is meshed to one end of the spline sleeve; spline teeth at three parts are uniformly removed on the spline sleeve; four spline teeth are removed at each removing part; the spline sleeve transmits torque to the primary sun wheel, and the transmission torque at the part is the smallest, so that the impact on the whole shield machine is the smallest if the transmission at the part is failed. The number of the teeth, of the spline sleeve, matched with the primary sun wheel is reduced, so that the matched with the primary sun wheel is reduced by 12; under the condition that the torque of the shield machine is increased infinitely, the matched part of the spline sleeve and the primary sun wheel is failed in the first place, and the spline sleeve is damaged but can be replaced easily, so that the important parts in the shield machine can be effectively protected, and the parts such as the spline sleeve which can be replaced easily are given up.
Description
Technical field
The present invention relates to technical field of engineering machinery, be specifically related to the presetting safty device of a kind of shield machine main driving retarder input spline.
Background technique
Along with the fast development of China, metropolitan population rapid expansion, the traffic pressure in whole city also strengthens increasingly, through expert's feasibility study, uses subway or light rail to be solve the most effective way in urban traffic pressure.In the construction of subway and light rail, our the most frequently used machinery is exactly shield machine, and what using now is all overseas equipment substantially, becomes more and more important to the care and maintenance of overseas equipment.
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 speed reducer 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 speed reducer.China's dependence on import always in the last thirty years, seriously constrains subway, highway, the cost of Concerning Railway Tunnel Construction and paces.
Chinese invention patent 201210079129.7 discloses a kind of without cutter head type balancing earth-pressure shielding machine, its power plant are made up of transfer case and the retarder be connected with transfer case and drive motor, the front end being arranged in the transfer case of the actuating unit of the shield machine first half is fixed on the active clapboard in earth pressure balance cabin, and the retarder be connected with transfer case and drive motor are supported by sliding device.Although disclose use retarder in this disclosure, do not propose to adopt large power gearbox for shield machine.
Chinese Patent Application No. 200810231114.1, disclose a kind of high power third-level planetary reduction gear for balancing earth-pressure shielding machine, its retarder is secondary by input planet gear, intermediate planetary gear is secondary, output planetary gear pair combines, its structure can adopt powerful retarder to a certain extent, but the bearing capacity for 24 Wan Niu meter but reaches less than requiring, harsh execution conditions can not be met.
If burst runs into severe geological state in the process of shield machine work, cutter head torque moment can be caused greatly, very easily damage main bearing of shield machine.
Summary of the invention
Technical problem to be solved by this invention is that providing a kind of effectively protects retarder and main bearing, and input end spline damages simultaneously, the presetting safty device of the shield machine be also convenient for changing main driving speed reducer input spline.
Technical problem to be solved by this invention realizes by the following technical solutions:
The presetting safty device of a kind of shield machine main driving retarder input spline, be applied to shield machine main driving retarder input end, comprise the input motor for driving retarder, the output terminal of described input motor is connected with spline housing, one end of described spline housing is engaged with one-level sun gear, described spline housing is rejected the spline tooth at three positions in uniform way, four spline tooths are rejected at each rejecting position, this spline housing passes to one-level sun gear moment of torsion, because transmitting torque is herein minimum, if transmitting inefficacy is herein minimum on the impact of whole shield machine, therefore the present invention is exactly the number of teeth that minimizing spline housing engages with one-level sun gear, 12 are just decreased like this with the number of teeth that coordinates of one-level sun gear, when shield machine moment of torsion infinitely increases, the position allowing it lose efficacy at first is exactly the cooperation place of spline housing and one-level sun gear, cause the damage of spline housing, spline housing is easy to again change, so just effectively can protect the strength member in shield machine, sacrifice the easily changeable part of spline housing.
Described one-level sun gear exports one end and is connected with primary planet wheel, and described primary planet wheel is connected with primary planet carrier, and described primary planet carrier is connected with primary annulus;
Described secondary transmission device comprises the secondary solar gear be in transmission connection with primary planet carrier, and described secondary solar gear is connected with secondary planet wheel, and described secondary planet wheel is connected to secondary planet frame, and described secondary planet frame is connected with secondary gear ring;
Described three gear stages comprise the three grades of sun gears be in transmission connection with secondary planet frame, and described three grades of sun gears are connected with third-level planetary wheel, and described third-level planetary wheel is connected with third-level planetary frame, and described third-level planetary frame is connected with three grades of gear rings.
The invention has the beneficial effects as follows: the object of the invention is to effectively protect the gear in speed reducer and bearing; severe geological state is run into especially in order to happen suddenly in the process of shield machine work; cutter head torque moment greatly; damage main bearing of shield machine; in input end control torque total amount; when exceeding provided moment of torsion; input end spline lost efficacy; effectively speed reducer and main bearing are protected; input end spline damages simultaneously; also be convenient for changing, be conducive to the fast quick-recovery of equipment performance.
