The purpose of the utility model is realized like this:
the utility model provides a high-efficient sealed gear box of power input end, includes box, input shaft, motor mount pad and input motor, the motor mount pad is installed outside the box, the input motor is fixed on the motor mount pad, the input shaft rear end passes first bearing, spiral sealing ring in proper order, connects the shaft coupling after covering thoroughly, the input shaft passes through coupling joint input motor, spiral sealing ring is equipped with one-way helicla flute.
Preferably, the rear end of the input shaft is supported in the case by a first bearing, and the front end is supported in the case by a second bearing.
Preferably, the spiral sealing ring is made of 45 steel.
Preferably, the spiral sealing ring is provided with an inner hole corresponding to the input shaft, and the inner hole is provided with a one-way spiral groove.
Preferably, an avoiding groove is formed in one end, close to the first bearing, of the spiral sealing ring, and the spiral sealing ring only contacts with the outer ring of the first bearing and does not contact with the inner ring of the first bearing.
Preferably, the transparent cover is fixed on the box body.
Preferably, a dustproof ring is arranged between the transparent cover and the input shaft.
The utility model has the advantages that:
the utility model discloses when the input shaft is rotatory, the trend of one-way helicla flute is from outside-in, and fluid flows back to the box along one-way helicla flute, can not outwards leak, has avoided fluid entering motor, has improved sealing performance, adopts 45 steel difficult losses simultaneously, has guaranteed the life of gear box.
