Description
Technical field
This utility model is related to a kind of reductor and in particular to a kind of special three-ring gear reducer of steel billet roller-way.
Background technology
Steel billet roller-way be steel mill infrastructure device, be used to convey the article such as the steel billet of molding, section bar.Due to such steel
Material has the heavy weight feature of large volume, does not have other equipment that roller-way can be replaced to convey such steel on a production line, so
The reliability requirement of roller-way is very high, and when roller-way runs, steel billet can produce powerful impact force to roller-way, and part impact force
Can pass on the reductor of drive part, so needing reductor to have sufficiently large shock resistance, anti-overload ability.Due on roller-way
Limited separation between each roller, and the part on roller-way is a lot, so the size requirement to reductor is higher.And now use
In reductor, impact resistance, overload performance are good, and volume is excessive, and the installation that reductor includes motor is extremely difficult；Small volume
Reductor such as modularization speed reducing motor then can not withstand shocks load, and overload performance is bad, be easily caused large area and stop, sternly
Ghost image rings the production conveying of steel billet.
Content of the invention
For solving deficiency of the prior art, the purpose of this utility model is to provide a kind of compact conformation, impact resistance energy
The special three-ring gear reducer of steel billet roller-way that power is strong, overload performance is excellent and maintainability performance is strong.
The technical scheme that this utility model is taken is：
The special three-ring gear reducer of steel billet roller-way, including casing, puts down in casing for three be provided with same level
Row rotating shaft, the two ends of each rotating shaft are supported on casing by bearing, and the same heterodoxy of intermediate rotary shaft and both sides rotating shaft is stretched out outside casing, and three
Three piece of three ring flat-plate is cased with rotating shaft, both sides rotating shaft is connected with the annular distance of the both sides of three ring flat-plates through bearing, intermediate rotary shaft is provided with
External gear, the internal gear cooperation at described external gear and three ring flat-plate centers is it is characterised in that the rotating shaft of described both sides is eccentric bent
Axle, differs three sections of bent axles for 120 degree for adjacent segment in the middle part of the rotating shaft of both sides, the both sides annular distance of three piece of three ring flat-plate respectively with three sections
Bent axle corresponds to, and the rotating shaft of both sides each connects input motor or wherein one rotating shaft connects input motor, and another rotating shaft connects system
Dynamic device or encoder, the external part of described jackshaft is connected with table roller, and the both sides of described table roller are respectively arranged with bullet
Property shock absorption trolley device.
Further, the two ends diameter of described three sections of bent axles is identical, and the diameter of another section of bent axle is less than other two sections, diameter
It is cased with little crankshaft section compensating axle sleeve.
After taking above technical scheme, the beneficial effects of the utility model are：
1. two high speed shafts design for integral one-piece mainshaft, wherein one be input shaft, can motor direct connection, in addition one only
It is used for the reductor adnexa such as brake, encoder is installed, is designed as bi-motor input also dependent on service condition, output gear is
Hollow sleeve output design, for installing roller spindle nose, this reductor is fixed by roller spindle nose and two sets of elastic shock attenuation pull bars.
2. two high speed shafts of three-ring gear reducer design for integral one-piece mainshaft, and described reductor is motor direct-connection type, subtracts
Fast machine can also can bi-motor input in single motor input, and described output gear is that cartridge type couples roller spindle nose, described reductor
Two sets of elastic shock attenuation pull bars are installed, reductor is fixed by roller spindle nose and two sets of elastic draw bars, and described shock absorption trolley is by butterfly bullet
The parts such as spring are constituted, for buffering the impulsive force of steel billet.
