Background technology

At present, the gear-box that is used in the material loading rollgang in ribbon steel, the hot strip rolling production line is generally multi roll, its structure is: a long connecting axle is housed in gear-box, is equipped with severally to meshing gear on this connecting axle, the every pair of meshing gear drives a conveying roller and rotates.This structure exists deficiency to be, adopt multi roll gear-box volume huge, connecting axle is longer, block, case lid are foundry goods, because part does not allow leakage of oil than big and this matching requirements block, case lid faying face precision height, requires to be parallel to each other between each dead eye that then links to each other with roller, thereby bring great difficulty for rough-cast and machined, increased processing cost simultaneously; Because connecting axle is slender axles, many shoulders structure, bring very big difficulty for the processing of part and the integral installation of device again.The material loading rollgang belongs to the bigger equipment easy to wear of load-bearing in actual production in addition, need often keep in repair, change part, and need take a lot of times when keeping in repair at every turn, causes the production line temporary cessation of production, therefore influences production efficiency.

Summary of the invention

The utility model provides a kind of be easy to process, reduce manufacturing cost and material loading rollgang for ease of maintenaince for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of material loading rollgang, comprise base, gear-box be housed on the base, the connecting axle that shaft coupling is housed two ends is housed, be equipped with on the connecting axle that drive bearing, drive bearing are contained in the bearing block in gear-box, be equipped with on the end face of drive bearing and be equipped with in bearing (ball) cover, the conveying roller that roller axle, roller axle two ends are equipped with roller bearing, roller bearing is contained in the roller axle bearing, at base stock guide is housed, it is characterized in that: the bevel gear that pair of meshing is housed in gear-box, driving bevel gear is housed on the connecting axle, driven bevel pinion is housed on the roller axle.

The utility model can also adopt following technical measures:

Have bearing block on the described gear-box.

The bearing positioning sleeve is installed between described driving bevel gear and the drive bearing, and the other end of driving bevel gear links to each other with the connecting axle shaft shoulder.

The bearing positioning sleeve is housed between described driven bevel pinion and the drive bearing, and the other end of driven bevel pinion is equipped with the fastening catch by bolt.

Have inspection hole cover on the described gear-box case lid.

Advantage and the good effect that the utlity model has are: because the utility model adopts independent small box, the a pair of bevel gear that closes of breathing heavily is housed in the gear-box, the volume and the working (finishing) area of gear-box have been reduced like this, be convenient to the casting processing of blank, easier assurance required precision, do not need to take heavy duty machine tools, save raw material, reduce production costs; Short connecting axle is housed in gear-box, simple in structure, be convenient to processing, convenient disassembly during maintenance adopts shaft shoulder location, and locating effect is reliable; Connecting axle is contained on the gear-box block by the support of drive bearing, on the end face of drive bearing bearing (ball) cover is housed, bearing (ball) cover adopts directly embedded being contained in the gear-box block, can effectively eliminate the vibration of machinery, be convenient to installation and maintenance, be connected by roller chain coupling with a following group gear-box at gear-box, effectively guarantee moment of torsion, simultaneously for convenience detach, the take-down time of part enhances productivity when shortening maintenance greatly.The utility model also has advantages such as simple in structure, reasonable in design in addition.
