Background technique
Along with high-speed rod project in recent years constantly increases in China, a lot of privately owned capitals change the high line of investment over to, and private firm's insufficient funds become the common fault of private firm, and this just requires us to reduce cost under the constant situation of existing equipment usability.Wherein finish rolling district master motor adopts direct current generator to replace alternating-current variable frequency motor to become the emphasis that reduces whole line cost.In former design, the power source of the high line of whole piece is selected ac variable-frequency electric motor for use, control system adopts the ABB frequency-changing control system, but because of domestic technique falls behind, can't do the corresponding techniques support to equipment debugging and normal problems occured in operation, run into this type of situation and often will engage the foreign technology expert to solve, increased original cost virtually, also caused the increase in plant maintenance cycle simultaneously.After adopting direct current generator, control system is simplified significantly, and the support of domestic technique can solve any problem of debugging and emerged in operation fully.The expenditure contrast of two aspects adopts direct current generator can save ten thousand yuans of 500-600.But because of the direct current generator maximum (top) speed does not reach application requirements, must make amendment to the speed ratio of the existing booster engine of high-speed rod, find by calculating the back, speed ratio and former speed ratio differ 0.2-0.3, because of whole line finish rolling district has passed through the practical proof of decades at home, this just requires us to adopt increases a booster engine and guarantees newly-designed requirement between former booster engine and direct current generator.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, stressed evenly, little, the long service life of operating noise, be convenient to safeguard and meet the vertical speed change speedup box of whole differential surface speed coupling.
The utility model adopts following technological scheme: the vertical speed change speedup box of a kind of high-speed rod, it comprises case lid, end cap, middle casing, first injection loop, end cap, outside framework oil seal, axle sleeve, lower box, middle cover, shaft end ring, four spot contact bearings, cushion, second injection loop, roller bearing, spacer sleeve, driven gear, output shaft, driving gear, transmission shaft, the oil return flange, it is characterized in that: the driving gear hot charging is on transmission shaft, distinguish the hot charging spacer sleeve successively, roller bearing, second injection loop is installed, cushion, hot charging four spot contact bearings, with shaft end ring that four spot contact bearings are spacing, the other end of transmission shaft is the hot charging roller bearing successively, first injection loop, axle sleeve, the transmission shafts string that assembles is installed in the lower box casing in the installation; The driven gear hot charging is on output shaft, distinguish hot charging spacer sleeve, roller bearing, installation second injection loop, cushion, hot charging four spot contact bearings successively, with shaft end ring that four spot contact bearings are spacing, the output shaft the other end is hot charging roller bearing, first injection loop, axle sleeve successively, the output shaft axle string that assembles is installed in the middle casing, the mould assembling lid, in four spot contact bearing sides of transmission shaft and output shaft cushion and end cap are installed respectively, outside framework oil seal and end cap are installed at the corresponding the other end.
Adopt after the technique scheme, this vertical speed-increasing transmission has following advantage:
1, the bearing place adopts the thin oil pressure lubrication, has effectively prolonged the working life of bearing.
2, gear adopts dynamic balancing technics to reduce the vibrations of complete machine in course of working.
3, adopt split type processing, each endoporus of casing assembling fine finishing, the machining accuracy height has guaranteed the size and the form and position tolerance of each endoporus.
4, complete machine structure is simple, is beneficial to the maintenance and the maintenance of assembling and production scene.
5, operating noise is little, and transmitting torque is big.
6, cushion is installed in the box house position of bearings, has effectively been delayed the axial in the running long-term impact of complete machine.
7, all there is the oil return flange both sides, and left line and right line all can use.
8, most of part can exchange with former speedup box in the casing.
