Description
Technical field
The utility model belongs to metallurgy industry steel rolling equipment, is specifically related to a kind of carbon steel wire rod mm finishing mill unit step-up gear.
Background technology
Straight carbon steel finishing wire unit transmission system, comprises mm finishing mill unit part and step-up gear part.This step-up gear is according to user's particular/special requirement, in order to meet the step-up gear of the continuous no twist rolling feature of wire rod and design gear each portion gearratio.Generally speaking straight carbon steel wire rod finishing mill group system is when equipment is gone into operation, and is to choose motor drag plant capacity according to the existing shaping transmission power needed for mm finishing mill unit system.But in specific situation, producer can according to own situation, selected motor in advance, because the power of motor and rotating speed often only have certain scope, so can not mate the continuous rolling requirement meeting wire rod with mm finishing mill unit transmission system.But mm finishing mill unit part is due to complex structure, standardization, so should not redesign, but step-up gear part, because structure is relatively independent, the difficulty of design is less.So can design it according to specific situation.Expand the scope of wire rod rolling, meet the Production requirement of different user.In addition, because high-speed rod is in the operation of rolling, requires at a high speed, nothing is turned round, micro tension milling, because pass is fixed, so the gearratio that often frame finishing mill is final and its rolling rotating speed have certain contacting.Rated speed and the power of the motor selected in advance due to steel mill are certain, so cannot match with mm finishing mill unit gearratio, meet the rolling requirements of high-speed rod.
Summary of the invention
The purpose of this utility model is to provide one can match with mm finishing mill unit gearratio, realizes the continuous no twist rolling of carbon steel wire rod, meets the carbon steel wire rod mm finishing mill unit step-up gear of the motor drag equipment that user selectes in advance.
For achieving the above object, the technical solution adopted in the utility model is: comprise casing and be arranged on one end in casing and stretch out the active power shaft that casing is connected with motor, active power shaft is provided with driving gear, the first passive output gear shaft that casing is stretched out in one end is also installed in the both sides of casing inner pinion gear, second passive output gear shaft, the gear that first passive output gear shaft is installed is meshed with driving gear, transition gear is provided with between second passive output gear shaft and driving gear, second passive output gear shaft is meshed with transition gear respectively with driving gear.
The described driving gear number of teeth is 157 teeth, and the gear number of teeth that the first passive output shaft is installed is 42 teeth, and the middle transition gear number of teeth is 60 teeth, and the gear number of teeth that the second passive output gear shaft is installed is 50 teeth.
The utility model realizes the high speed of two output shafts and the transmission of low speed by gear drive.By being connected with mm finishing mill unit, continuous, the nothing that finally realize carbon steel wire rod are turned round, micro tension milling technological requirement.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Detailed description of the invention
Below in conjunction with accompanying drawing, structural principle of the present utility model and operation principle are described in further detail.
See Fig. 1, the utility model comprises casing 1 and is arranged on one end in casing 1 and stretches out the active power shaft 2 that casing is connected with motor, active power shaft 2 is provided with driving gear 3, the first passive output gear shaft 5 that casing is stretched out in one end is also installed in the both sides of casing 1 inner pinion gear 3, second passive output gear shaft 6, the gear that first passive output gear shaft 5 is installed is meshed with driving gear 3, transition gear 4 is provided with between second passive output gear shaft 6 and driving gear 3, second passive output gear shaft 6 is meshed with transition gear 4 respectively with driving gear 3, the driving gear number of teeth of the present utility model is 157 teeth, the gear number of teeth that first passive output shaft 5 is installed is 42 teeth, the middle transition gear number of teeth is 60 teeth, the gear number of teeth that second passive output gear shaft 6 is installed is 50 teeth.
Gearratio of the present utility model is different from the gear of the carbon steel wire rod mm finishing mill unit step-up gear of standard.Under meeting user and making the prerequisite of motor by oneself, reach carbon steel wire rod at a high speed, without turning round, the requirement of micro tension milling, meet the requirement of carbon steel wire rod rolling percentage elongation.In the design process, must redesign the gearratio of this step-up gear, because say from design angle, the gearratio of the mm finishing mill unit gear that standardization uses is redesigned, not science, operational difficulties, against equipment use convenience etc.So select the step-up gear gearratio relatively independent to structure to design.Can reach on improvement purpose basis equally, design work is relatively simple.
The utility model is by the redesign to the transmission engage ratio of step-up gear driving gear, middle transition gear and two passive tooth wheel shafts, and make this step-up gear while realizing speedup and point speed, two driven gear output shafts reach different rotating speeds.By being connected with mm finishing mill unit, the rolling percentage elongation that the final mill speed of mm finishing mill unit each frame finishing mill and gearratio relation and carbon steel wire rod are required that combines with the gear ratio of mm finishing mill unit matches.Realize the high speed of carbon steel wire rod, nothing is turned round, micro tension milling.Under meeting user and making the prerequisite of motor by oneself, realize the rolling of wire rod.
The utility model, by driven by motor driving shaft 2, realizes the input of power, and driving shaft 2 and driving gear 3 adopt split-type structural, become gear shaft entirety by hot charging.Power is meshed with the gear that the first passive output gear shaft 5 is installed by high speed driving gear 3 simultaneously, transition gear 4 is provided with between second passive output gear shaft 6 and driving gear 3, second passive output gear shaft 6 is meshed with transition gear 4 respectively with driving gear 3, and power exports on the first passive output gear shaft 5, second driven gear output shaft 6 after dividing speed and speedup the most at last.By middle transition gear 4, realize the conversion of passive output gear shaft direction of rotation and the high and low difference of rotating speed.Be connected with mm finishing mill unit part by passive output gear shaft again, realize the gearratio requirement of final mm finishing mill unit, meet rolling mill practice.
