Technical field
The utility model relates to a kind of reduction box, especially a kind of multi-roll mill reduction box, and specifically a kind of rolling thin strip cold material keeps off reductors with mill with two.
Background technology
Along with advancing by leaps and bounds of modern rolling technique, modern milling train does not develop towards there being turning round direction at a high speed gradually, and inclined to one side eight rollers, 12 rollers, mill are present popular rolling equipments.Existing mill is a kind of purposes multi-roll mill very widely, be mainly used in the thin strip cold material, this milling train needs four power shafts, and can adjust mill speed according to the thickness of band, and the reductor that existing this kind equipment is joined all is to adopt the spur gear reducing gear, and needs multi-stage speed-reducing, and output speed must rely on motor to slow down, cause volume big, complex structure.Therefore, design a kind of employing one-level and slow down, the two-stage variable block, the multipurpose reductor that can have four output shafts simultaneously is the keys that solve this type of problem.
Summary of the invention
The purpose of this utility model is that volume is big at existing mill reductor gear complexity, and the problem that manufacturing cost is high designs a kind of herringbone bear of using and carries a gear as passing, and the mill of one-level reduction of speed drive mechanism keeps off reductors with two.
The technical solution of the utility model is:
A kind of mill keeps off reductors with two, comprise input gear shaft 1, it is characterized in that described input gear shaft 1 is provided with in-line gears 2,13, floating gear 3 engagements on in-line gears 2 and the intermediate gear shaft 7, on in-line gears 13 and the intermediate gear shaft 7 another floating gear 6 being installed is meshed, on intermediate gear shaft 7, described floating gear 3, be equipped with between 6 and connect gear 6, the sliding gear collar 5 that can link to each other with floating gear 3 or floating gear 6 is installed on the described connection gear 6, the output of described intermediate gear shaft 7 is provided with herringbone bear 14, thereby herringbone bear 14 is meshed with one-level output herringbone bear 9 on two one-level output shafts 11 simultaneously and drives two one-level output shafts 11 and rotate, one-level output herringbone bear 9 on each one-level output shaft 11 is exported herringbone bear 8 with the secondary on the corresponding secondary output shaft 10 and is meshed, and rotates thereby drive two secondary output shafts 10.
Described sliding gear collar 5 is connected with shifting fork device 12, and shifting fork device 12 is connected with operating grip 16.
The beneficial effects of the utility model:
The utility model adopts one-level to slow down, and the drive mechanism that simplifies greatly makes volume subordinate significantly.
It is output gear that the utility model adopts the herringbone bear of bearing capacity maximum, has increased driving torque greatly, helps prolonging the service life of gear.
Utility model adopts the slip teeth structure can realize the output of two rotating speeds, has guaranteed the reliability of exporting by mechanical device.
