Description
Technical field
The utility model relates to speed reducer, specifically a kind of metallurgy industry tension leveller of continuous casting machine special reduction gear.
Background technique
Casting straightening is the process that continuous casting billet is pulled out and aligned with certain drawing speed, is the basic technology of modern steel mill
One of, it is completed by withdrawal straightening machine.Therefore the reliability of withdrawal straightening machine transmission device requires high, need speed reducer have sufficiently large antivibration,
Shock resistance, anti-overload ability.Traditional withdrawal straightening machine hardened face gear speed reducer, shock resistance, anti-overload ability are insufficient.And it is existing
The transmission of (in metallurgical ministerial standard YB/T 079-1995) LLSH type continuous casting steel machine withdrawal straightening machine is with tailored version three-ring speed reducer using single
It is exported after more transmissions built in box body, disadvantage: multi-layer box, structure is complicated, and process and assemble is difficult, maintenance difficult, and installation is multiple
Miscellaneous, production, use cost are high.
Summary of the invention
Big in order to solve existing continuous casting steel machine reducing gear for straightening machine single machine volume, production, use cost are high, overload performance
The problem of not enough the deficiencies of leads to poor reliability, the purpose of the utility model is to provide a kind of compact-sized, antivibratioves, impact resistance
The dedicated three-ring gear reducer of continuous casting steel machine withdrawal straightening machine that ability is strong, overload performance is excellent and maintainability performance is strong.
The technical solution adopted in the utility model is: a kind of metallurgy industry tension leveller of continuous casting machine special reduction gear, feature exist
In: it is made of upper and lower two three-ring gear reducers, the upper cover of lower three-ring gear reducer is equipped with mounting hole, and mounting hole and upper tricyclic are slowed down
The lower margin hole of box body is fixedly connected through bolt, and two three-ring gear reducer structure is identical and structure is symmetrical, and tricyclic is slowed down
Machine includes cabinet, upper cover, high speed input shaft, gear set, the first jackshaft, output shaft, the second jackshaft and three internal tooth torus
Piece, output external gear, high speed input shaft, the first jackshaft, output shaft, the second jackshaft are successively supported on cabinet through upper cover lid
Dress, high speed input shaft are driven the first jackshaft, the first jackshaft and the second jackshaft through gear set and drive in three through eccentric bushing
120 ° of gear ring plate are made phase difference plane motion, and the output external gear of internal gear ring plate inner ring gear and output shaft is nibbled for few teeth difference
It closes；High speed input shaft, the output shaft of upper and lower two three-ring gear reducers are inputted in the same direction, are exported.
The utility model internal gear ring plate inner ring gear with the output external gear few teeth difference of output shaft is multiple tooth engages simultaneously, shape
At large transmission ratio output power；Lower three-ring gear reducer and upper three-ring gear reducer are matched by mounting hole and lower margin hole stacks symmetrical peace
Dress, can effectively improve that antivibration, impact resistance ability be strong, overload performance, avoid conventional individual speed reducer labyrinth process and assemble, dimension
Repair difficulty.

Specific embodiment
It is described further below in conjunction with drawings and examples.
Shown in Fig. 1-4, a kind of metallurgy industry tension leveller of continuous casting machine special reduction gear is by 1,2 group of upper and lower two three-ring gear reducers
At the upper cover 4 of lower three-ring gear reducer 2 is equipped with mounting hole, and the lower margin hole of mounting hole and upper three-ring gear reducer cabinet is fixed through bolt
Connection, upper and lower two three-ring gear reducer structure is identical and structure is symmetrical, and every three-ring gear reducer includes cabinet 3, upper cover
4, high speed input shaft 5, gear set 6, the first jackshaft 7, output shaft 8, the second jackshaft 9, internal gear ring plate 10, output external gear
11, eccentric bushing 12, high speed input shaft 5, the first jackshaft 7, output shaft 8, the second jackshaft 9 are successively supported on cabinet through upper cover
Lid dress, high speed input shaft are driven the first jackshaft, the first jackshaft and the second jackshaft through gear set 6 and drive three through eccentric bushing 12
120 ° of internal gear ring plate make phase difference plane motion, and the output external gear of internal gear ring plate inner ring gear and output shaft is few tooth
Difference engagement；High speed input shaft, the output shaft of upper and lower two three-ring gear reducers are inputted in the same direction, are exported.
