Description
Technical field
A kind of deceleration device is the utility model is related to, specifically a kind of milling pick machine speed reduction gearing.
Background technology
The fluted disc of existing milling pick machine is to drive rotation to realize that milling is dug through chain drive by the reductor above put, the biography of chain
Dynamic stationarity is poor, and load-carrying properties are poor, is unsuitable for long-term high-strength operation milling pick, and after chain abrasion, envoy causes greatly away from change
Disconnect, hidden danger safe to use be present, service life is short.
The content of the invention
For the above-mentioned deficiency of prior art, the utility model, which provides a kind of structure, to be built and gathers, and is operated steadily, load-carrying properties
Machine speed reduction gearing is dug in height, safe to use, long lifespan milling.
The technical solution of the utility model is：Machine speed reduction gearing is dug in a kind of milling, it is characterised in that：Including upper box,
Middle housing and lower box, upper box is interior to be provided with shaft coupling, input gear axle and one-level above cylindrical gear drive, inputs
Each parallel axes of gear shaft and one-level above cylindrical gear drive from top to bottom be arranged in parallel and through taper roll bearing branch
Support is in upper box, the shaft end connection shaft coupling of input gear axle, the increment engaged transmission one-level above cylinder of input gear axle
Gear drive, the middle housing are connected under upper box, are worn on the corresponding side plate of middle housing two and are connected to jackshaft, middle
Supported on axle through cylinder roller bearing by idler gear, one-level above cylindrical gear drive engaged transmission idler gear, institute
Stating lower box includes cylinder shell, inner barrel, and inner barrel is connected to middle housing lower end and is arranged in cylinder shell, is passed through in inner barrel
Taper roll bearing, which is worn, connects output shaft, and fixedly sleeved output gear, output gear engage with idler gear on output shaft, output shaft
End be fixedly connected with cylinder shell end face through bolt, the fixedly sleeved milling pick fluted disc in cylinder shell both ends.
Support tube is fixedly connected with the inner barrel, inside and outside barrel and the cylinder shell and output between centers of support tube are equipped with
Wear-resistant seal packing ring.
The utility model is in use, milling digs electromechanical machine through the shaft coupling transmission input gear axle in upper box, input gear
Axle engaged transmission one-level above cylindrical gear drive, in one-level above cylindrical gear drive engaged transmission middle housing
Idler gear, the output gear in idler gear engaged transmission lower box, cylinder shell rotation, cylinder shell are driven through output gear
The fixedly sleeved milling pick fluted disc rotation thereon is driven, realizes that operation is dug in milling.By stage-geared, structure, which is built, gathers, transmission
Operate steadily, load-carrying properties are high, safe to use, long lifespan.
