As preferably, be provided with flange around the receiving hole on the described casing inner bottom surface, its inner bottom is provided with seam, and is equipped with bearing within it.Being provided with of this flange on the one hand saved material, reduced working area, on the other hand, makes that the tank floor thickness of gear-box is basic identical, and what prevented to cause because of expanding with heat and contract with cold breaks.
As preferably, be provided with flange around the output shaft through hole of described reduction gearbox for electrical motor, be provided with seam in it, the bottom surface of seam is higher than the bottom surface of casing.Being provided with of this flange can be played the purpose of saving material and reducing working area equally, the bottom surface that is higher than casing in addition because of the bottom surface of its seam so form a boss on the bottom surface of casing, has reduced the thickness of tank floor like this, simultaneously also reduce the height of casing, and saved material.
As preferably, on casing, the seam of output shaft through hole is provided with oil sealing to the output shaft of described reduction gearbox for electrical motor by bearing hinge joint, described flange and height be 2.0-5.0mm, seam and height be 0.5-2.0mm, gear-box airtight chamber is cylindrical.Such structure can reduce the seepage of gearbox medium gear lubricating oil, has improved sealability, and it is well lubricated that output shaft bearing is obtained all the time.
As preferably, be provided with seal ring between the casing of described reduction gearbox for electrical motor and the end cap; Be respectively equipped with the retaining thread hole on four angles of described casing, described end cap is provided with corresponding with it through hole, and both pass through screw.The setting of sealing circle has prevented the leakage of lubricating oil between motor and end cap, thereby the sealability that has improved, described end cap and casing pass through screw, because of screw does not pass seal chamber, so avoided the leakage of lubricant oil in the screw slit, so further improved the sealability of complete machine.Simultaneously, motor is provided with through hole, is provided with corresponding fixing threaded hole in the bottom of end cap, also passes through screw between the two.
As preferably, the transmission shafts at different levels of the reducing gear of described reduction gearbox for electrical motor be arranged in parallel; End cap equates substantially with the diameter of casing.
As preferably, the reduction gears mechanism of described reduction gearbox for electrical motor is the level Four reduction gears mechanism, and flange will articulate four receiving hole envelopes at level Four gear-driving rod two ends in it, have good deceleration effect.
Therefore, it is more convenient that the present invention has compact structure, manufacturing and assembling, saves material, and low cost of manufacture, and characteristics such as complete machine good airproof performance are a kind of reduction gearbox for electrical motor with wide application prospect.
