Description
Technical field
The utility model relates to a kind of cycloid speed reducer, specifically a kind of sewage treatment cycloid speed reducer.
Background technique
Agitating device speed reducer generallys use vertical-type planetary gear drive, column gear transmission, cycloidal gear transmission, motor
Positioned at the top of whole equipment, lower part dress cooling fan or stirrer paddle are exported.Have the following deficiencies: 1, general-purpose vertical planet
Gear transmission speed reducer is not subject to axial force, and planetary reducer internal bearings are more, structure is complicated, increase processing technology cost.
2, general-purpose vertical cycloidal gear transmission speed reducer bearing capacity is small, cannot bear downward axial force, low efficiency.3,
General column gear transmission speed reducer needs Multi-stage transmission, and volume is big, needs reshaping, be made into it is nonstandard could use, Bu Nengzhi
It connects and uses sewage treatment speed reducer.
Summary of the invention
Big, oil leak that the purpose of the utility model is to overcome general speed reducer volumes, is not subject to axial push away at unstable vibration
The disadvantages of power, provides the high speed ratio of a kind of with small vibration, hermetically sealed not permeable oil leak, stability big Novel sewage processing cycloid reduction
Machine.
The technical solution adopted in the utility model is: a kind of sewage treatment cycloid speed reducer, including motor, upper block, needle
Tooth shell, lower stand, cyclo drive mechanism, output shaft are fixedly connected with upper block through pin wheel housing on lower stand, support electricity on upper block
Machine, the cyclo drive mechanism that motor output shaft is placed in pin wheel housing through the connection of upper block, cyclo drive mechanism driving output shaft,
Be characterized in that: the output shaft is in lower stand from inside to outside successively through ball bearing and double cone roller bearing supports, lower stand
Lower connection bottom sealing socket, output shaft are worn the outer transparent cover for connecing bottom sealing socket lower end, are set on the output shaft of corresponding outer transparent cover inner wall
Dead ring is equipped with outside framework oil seal between dead ring and outer transparent cover inner wall, the outer transparent cover inner wall of corresponding outside framework oil seal is equipped with O-ring,
Mechanical seal is socketed on output shaft in bottom sealing socket.
It is equipped between the lower stand and bottom sealing socket and wears the interior transparent cover connect on output shaft, in the abutting of mechanical seal both ends,
Between outer transparent cover or between interior transparent cover and bottom sealing socket inner convex platform.
The motor output shaft is worn through ball bearing to be connect on upper block and is supported on upper block inner support sealing plate suitable for reading.
The cyclo drive mechanism includes eccentric bushing, capacity eccentric bearing, two Cycloidal Wheels, gear pin, pin shaft, pin shaft and output shaft
Disjunctor.
The lower stand design is in an inverted cone.
Mechanical seal is socketed on the motor output shaft, mechanical seal outer end pushes against inner support sealing plate, and inner end is defeated through motor
The positioning of shaft upper snap ring.
The utility model cycloid speed reducer output shaft is in lower stand through a pair of of tapered roller bearing and one group of ball bearing branch
Support, can bear biggish bi-directional axial thrust and radial force；And outside framework oil seal is filled on output shaft, and in outer transparent cover and defeated
O-ring, mechanical seal are set between shaft, effectively ensure the not permeable oil leak of speed reducer；It is designed on lower stand tapered and outside taper
Week setting mounting flange, is easily installed and takes into account reduction resistance of medium.
