Abstract
The utility model provides a special speed reducer for a round steel rolling line, which comprises a box body, an input shaft, a primary gear, a secondary gear, tertiary double helical gears, a first output shaft, a second output shaft and a middle shaft, wherein one end of the input shaft extends out of the box body, the gear arranged on the other end of the input shaft is in engagement transmission with the primary gear fixedly arranged at one end of the middle shaft, the gear arranged on the other end of the middle shaft is in engagement transmission with the secondary gear fixedly arranged on the first output shaft, the tertiary double helical gear arranged on the first output shaft is in engagement transmission with the tertiary double helical gear arranged on the second output shaft, an eccentric sleeve is arranged between the outer ring of a bearing and a box body bearing hole, the axial line of the first output shaft and the axial line of the second output shaft are positioned on the same vertical line, the axial line of the first output shaft, and the axial line of the middle shaft and the axial line of the input shaft are positioned on the same horizontal line. The special speed reducer provided by the utility model has the beneficial effects that the technical characteristics of low speed, heavy load, large impact load, frequent impact times and continuous work are realized, meanwhile, good engagement of the gears can be ensured through the regulation of the eccentric sleeve, the service life is prolonged, and the precision and the reliability degree are improved.
Description
Technical field
The utility model belongs to the reductor apparatus field, especially relates to a kind of round rolling line special reduction gear.
Background technology
Be used for the mechanism of transferring power and motion at present, the range of application of reductor is quite extensive, almost can see its trace in the transmission system of various machinery, and reductor has and slows down and increase the torque function.In different fields, reductor also there is different requirements.The reductor that for example is used for the round rolling line, require low speed, heavy duty, impact load big, the impact number of times is frequent, needs continuous operation simultaneously, along with China's steel rolling industrial boom, the continuous expansion of rolling shapes, the increase of output, the raising of mill speed, the increase of rolling load, require gear drive to have enough bearing capacitys, existing common reductor can not satisfy the demand of industry development.
Summary of the invention
A kind of round rolling line of the utility model special reduction gear, it is the reductor that is specifically designed to the round rolling line, its purpose will solve deficiency of the prior art exactly, it is big to make it satisfy low speed, heavy duty, impact load, impact the requirement that number of times frequently reaches continuous operation, simultaneously, make gear drive have high strength, high accuracy, high life and high-reliability.
The technical solution of the utility model is: a kind of round rolling line special reduction gear, comprise casing, power shaft, the one-level gear, secondary gear, three grades of double helical tooths, output I axle, output II axle and jackshaft, one end of power shaft stretches out outside the casing, gear on the power shaft other end and the one-level meshed transmission gear that is packed in jackshaft one end, gear on the jackshaft other end and the secondary gear engaged transmission that is packed on the output I axle, three grades of double helical tooths on three grades of double helical tooth engaged transmission output II axles on the output I axle, between bearing outer ring and the casing dead eye eccentric bushing is housed, the axis of described output I axle and output II axle on same vertical line, described output I axle, the axis of jackshaft and power shaft is on same horizontal line.
Described one-level gear and secondary gear are cylindric spiral gear.
