A kind of submersible machine speed reducer, comprise sealed electric-motor and reducing gear, described reducing gear comprises seal case, drive bevel gear and the driven wheel of differential of pair of meshing transmission are installed in seal case, wherein drive bevel gear is arranged on sealed electric-motor output shaft end, driven wheel of differential be arranged on the vertically disposed gear shaft of motor output shaft on, described seal case comprises left and right support plate, upper and lower cover plates, side cover plate and motor dress plate, wherein each cover plate is fixedly mounted on by fastening piece on the support plate of left and right at edge part, stretch out from left and right support plate respectively at the two ends of gear shaft, and be rotatably supported on the support plate of left and right by sliding bearing.
Described sliding bearing two ends are fixed on the support plate of left and right by inside and outside spindle nut respectively.
Described drive bevel gear is fixedly mounted on motor output shaft by pin.
Described driven wheel of differential two ends are fixed on gear by set screw nut.
Between the support plate of left and right, upper and lower sides is fixed with pole.
Be respectively equipped with flat key and left and right end round nut at gear shaft two output terminals.
Described sealed electric-motor comprises motor and can.
The beneficial effect of technical solutions of the utility model is:
1, structurally, the contained motor of the utility model submersible machine speed reducer is wrapped up by sealing configuration, becomes an independently structure, can enter wherein by anti-sealing; The bevel-gear sett of contained reducing gear is sealed by cover plate and motor dress plate, separates with sealed electric-motor; The output shaft of motor drives drive bevel gear to rotate, and drive bevel gear drives driven wheel of differential to rotate, and the gear shaft at driven wheel of differential place contains two output terminals, can drive low-speed motion machinery slowly to rotate.The sealing of the bevel-gear sett of the contained reducing gear of the utility model is to adopt cover plate etc. to seal, easy to loading and unloading, is convenient to maintenance and safeguards.
2, structurally, the utility model submersible machine speed reducer is made up of driven wheel of differential, drive bevel gear, cover plate, sealed electric-motor etc., be suitable for the deceleration requirement of small underwater movable machinery, and can export two low speed rotating shafts, drive two cover sub aqua sport machineries to do synchronously and slowly run; The sealing configuration of contained motor and the sealing configuration of reducing gear are separate, simple in structure, wherein reducing gear adopts bevel gear transmission, and functional reliability is high, overcome reducer structure complexity under one body swimming, functional reliability poor, keep in repair and safeguard inconvenient shortcoming.
3, to sum up, the utility model submersible machine speed reducer is simple in structure, and motor sealing structure and reducing gear sealing configuration are separate, reliable working performance, wherein reducing gear sealing configuration adopts dismountable cover plate to seal, and is convenient to maintenance and safeguards, therefore, be very suitable for promotion and implementation.
