As preferred, the output shaft of described reduction gearbox for electrical motor is by bearing hinge joint on casing, and the seam of output shaft through-hole is provided with oil sealing, and the height of the flange sum is the 0mm of 2. 0- 5., the height of seam sum is 0. 5-2. 0mm, and gear-box airtight chamber is cylinder.Such structure can reduce the seepage of gearbox medium gear lubricating oil, improve sealing property, and output shaft bearing can be made to be lubricated well all the time.
Preferably, being provided with sealing ring between the casing and end cap of described reduction gearbox for electrical motor；Fixing screwed hole is respectively equipped with four angles of the casing, the end cap is provided with corresponding through hole, both
Fixed by screw.The setting of the sealing ring prevents leakage of the lubricating oil between motor and end cap, so as to the sealing property improved, described end cap and casing is fixed by screw, because screw is not passed through seal cavity, so leakage of the lubricating oil in screw gap is avoided, so further increasing the sealing property of complete machine.Meanwhile, motor is provided with through hole, is provided with corresponding fixing threaded hole in the bottom of end cap, is fixed between the two also by screw.
Preferably, the power transmission shafts at different levels of the reducing gear of described reduction gearbox for electrical motor be arranged in parallel；The diameter of end cap and casing is of substantially equal.
Preferably, the gear reduction of described reduction gearbox for electrical motor is level Four gear reduction, flange will be pivotally connected four accommodating hole envelopes at level Four gear-driving rod two ends in the inner, with good slowing effect.
Therefore, the present invention has compact conformation, manufactures and assemble more convenient, saves material, and manufacturing cost is low, and is a kind of reduction gearbox for electrical motor with wide application prospect the features such as complete machine good airproof performance.Brief description of the drawings
