Description
[technical field]
The utility model relates to shield machine screw feeder deceleration technical field, is the improvement of Mitsubishi heavy industry machinery Co., Ltd. shield machine screw feeder drive unit, a kind of shield machine screw feeder double-motor driving device.
[background technology]
Screw feeder is the vitals of shield machine, and its function is that the foreign material such as earth, sandstone in tunnel are delivered to outside hole continually.
In Mitsubishi heavy industry machinery Co., Ltd. shield machine, what screw feeder drive unit adopted is " (the two inner curve radial motor+one-level gears of two cover low-speed bigs " connect screw feeder version, the problem of its existence is:
(1) the slow speed turbine stage driving of parallel axes is unreasonable: slow speed turbine stage pinion input torque 25630 × 2 (Nm), gear wheel (Z
2=68, m=12.0, b=205) transport to screw feeder moment of torsion up to 166000 (Nm), gear wheel carburizing and quenching, gear-grinding process difficulty are larger;
(2) because " low-speed big two inner curve radial motors " complex structure, technology difficulty are high, domestic rare manufacturer, thereby for cost up to hundred million yuan of shield machine majorities from external import, price is very expensive;
(3) application " the two inner curve radial motors of low-speed big " needs to be equipped with oil pressure control system etc.
[utility model content]
According to the retrieval to data at home and abroad, do not find to adopt bi-motor " the poor deceleration of primary speed-down+mono-tooth " version.The utility model object is to provide cost low, easy to maintenance, and a kind of shield machine screw feeder of service-strong double-motor driving device, realizes the production domesticization of shield member parts.Technical solutions of the utility model are as follows:
A kind of shield machine screw feeder double-motor driving device, comprise two drive motors, two pinions, center gear wheel, closing disk, support and cycloid driving members, described electric machine is on closing disk, and described pinion is connected in drive motors shaft extension end, and described closing disk device is on support.Dual-motors Driving theoretical foundation: " adopt four zone plate speed reducers of Dual-motors Driving double crank; can be in smooth operation under dynamic equilibrium state; at this moment two of two crank mechanical performances motor driven; slip characteristic one load that relies on motor when large rotating speed decline; load hour rise of rotational speed rule, makes to drive the automatic holding torque of two motors of same ring flat-plate gear and all carrying of power by the pinwheel on connecting rod." (Wen Bangchun " mechanical design handbook " volume 2.9-148 page)
In theory, slow speed turbine stage output torque is large, therefore should adopt the drive mechanism of many shuntings or multiple tooth engagement, adopts motor to connect cycloid driving member, and then twin shaft drives Fourth Ring plate output shaft simultaneously, makes screw feeder work done, and examination is compared:
(1) in Mitsubishi Heavy Industries Ltd's machinery Co., Ltd. shield machine, the two inner curve radial motors of low-speed big that the drive unit of screw feeder adopts, output torque T=25630 (Nm), output speed n=40rpm, one-level gear: Z
