Description
Technical field
The utility model relates to the hot rolling main transmission reduction gear box in a kind of non-ferrous metal processing industry, especially a kind of shunting hot-rolling mill main transmission reduction gear box.
Technical field
In the hot rolling field in non-ferrous metal; Generally all be to drive two output shafts simultaneously by a motor, in recent years, because the specification of non-ferrous metal single chassis hot rolling is increasing; This just needs the power and the moment of torsion gesture of expanded motor; Must cause the volume of motor to become big, the volume of gear-box also can increase thereupon, and the shared space of entire equipment is also very bigger.How adapting to the increasing demand of single chassis hot rolling specification, can reduce the shared space of entire equipment again, is the important topic of paying close attention in the industry.
Therefore manufacture and design and a kind ofly novel can satisfy instructions for use, utilize compact space, the non-ferrous metal hot rolling main transmission gearbox that can reduce master budget again greatly becomes of gear-box industry and presses for.
The utility model content
The purpose of the utility model is: to the at present big shared excessive practical problem in space of specification non-ferrous metal hot rolled plate rolling equipment, a kind of new shunting hot-rolling mill main transmission reduction gear box is provided.
The purpose of the utility model is achieved in that a kind of shunting hot-rolling mill main transmission reduction gear box, comprises casing, input gear shaft, output shaft, it is characterized in that:
A) described casing comprises upper box, middle casing and lower box, connects through bolt successively between them;
B) be provided with two groups of reducing gears forming by input gear shaft, intermediate gear shaft, first reduction gear wheel, second level deceleration gear wheel and output shaft in the casing; One group is passed through bearings between upper box and middle casing, and another group is passed through bearings between middle casing and lower box;
C) first reduction gear wheel is fixedly mounted on the intermediate gear shaft through key, and with the pinion of input in the gear shaft; Second level deceleration gear wheel is fixedly mounted on the output shaft through key, and with intermediate gear shaft in pinion.
In the utility model: described one group is passed through bearings between upper box and middle casing; Another group is meant between middle casing and lower box through bearings, input gear shaft, intermediate gear shaft and output shaft in one group through bearings in the joint portion of upper box and middle casing; Input gear shaft, intermediate gear shaft and output shaft in another group passes through bearings in the joint portion of middle casing and lower box.
In the utility model: the joint portion between upper box, middle casing and the lower box is provided with eccentric bushing, and the bearing block of input gear shaft is fixed on the joint portion of corresponding casing by eccentric bushing.
The advantage of the utility model is, because casing is divided into upper box, middle casing and lower box three parts, and the installation strong point of each all is located at the joint portion of upper, middle and lower casing, assembles very convenient; Because the joint portion of casing is provided with eccentric bushing in upper, middle and lower; The bearing block of input gear shaft is fixed on the joint portion of corresponding casing by eccentric bushing; Can change the centre-to-centre spacing of input gear shaft and intermediate gear shaft through eccentric bushing, regulate the pinion and the engagement of the first reduction gear wheel in the intermediate gear shaft situation of input gear shaft; Since with two groups independently reducing gear be assembled in the casing; Compact conformation not only; And precision is high, rotating speed is high, stationarity good, and especially two groups of reducing gears adopt independent motor to drive, and have promoted the transmitted power of gear-box; Make it can export bigger moment of torsion, the main transmission power of the utility model can reach more than the 9000KW, maximum speed can reach 1800rpm.
And the calculating of gear rotors at different levels being carried out the natural frequency of vibration; Can reach the transmission requirement of transmitting high-power, high pulling torque, high accuracy, high rotating speed, high stationarity; Can satisfy above, the maximum speed 1800rpm of hot rolled plate milling train main transmission power 9000KW, and for the technological requirement of vibration aspects such as self-vibration, resonance.
