Description
Technical field
This utility model relates to a kind of gear-box, especially a kind of transverse axis development machine gear-box, belongs to a kind of and boom-type roadheader corollary equipment.
Background technology
Boom-type roadheader is divided into horizontal shaft type and longitudinal axis formula.Development machine major part used at home is also the longitudinal axis.Longitudinal axis development machine and transverse axis development machine are respectively arranged with pluses and minuses.But due to transverse axis development machine light by about 1/3rd than the longitudinal axis of its weight in the case of equal-wattage, so it is more stable during the work of transverse axis development machine, and transverse axis development machine efficiency of loading is higher, according to Britain and the field experimentation of development machine company of Austria, in the case of power is the same with formation hardness, the production capacity of transverse axis development machine almost exceeds one times than the longitudinal axis！Certainly transverse axis development machine also has significant limitation, such as compares longitudinal axis development machine, and power required during transverse axis development machine slotting cut is bigger；The centripetal force of horizontal roadheader carrys out automatic walking mechanism, and this allows for walking mechanism needs bigger driving force, and needs frequent starting etc..
The most domestic coal mining enterprise is greatly developing mechanization, has driven the fast development of coal mine machinery.But domestic transverse axis tunneling machine cutting gear-box is substantially based on external product.But domestic transverse axis tunneling machine cutting gear-box is substantially based on external product.And complicated structure, maintenance cost is the highest, and people expect that traditional product is substituted by the new gear-box that can have compact conformation.
Utility model content
The purpose of this utility model is: for current development machine gear-box dependence on import, and the problem that structure is relative complex, it is provided that a kind of new transverse axis development machine gear-box.
The purpose of this utility model is achieved in that a kind of transverse axis development machine gear-box, including casing, power shaft and output shaft, it is characterized in that: power shaft is mutually perpendicular to deceleration bevel gear shaft, deceleration bevel gear shaft, idler shaft, drive shaft are parallel to each other, power shaft, bevel gear shaft, drive shaft all by bearings in casing, idle pulley is by bearings on idler shaft, and drive shaft two ends set one group of output planetary train respectively；Described power shaft transmits moment of torsion by deceleration bevel gear pair, deceleration bevel gear shaft transmits moment of torsion after being engaged with the gear wheel in drive shaft by the idle pulley on idler shaft, drive shaft two ends simultaneously drive the sun gear of two output planetary trains, the planetary gear bearing pin of output planetary train is fixedly mounted on casing, and the internal tooth coil of two output planetary trains is all as the outfan of development machine gear-box.
In this utility model: be additionally provided with transmission gear for lubricating pump on described deceleration bevel gear shaft, casing is provided with lubricating oil bath and forced feed lubrication oil duct, the terminal of forced feed lubrication oil duct for each spring bearing and for mesh tooth face provide lubricating oil jet.
In this utility model: the ring gear of power shaft and output planetary train is equipped with sealing device in the joint portion passing through casing.
The utility model has the advantage of: this utility model compact conformation, due to output shaft and power shaft orthogonal relationship, and profile is restricted, therefore input uses one-level bevel gear, centre adds the parallel axes of one-level band idle pulley, increase idle pulley for adjusting the centre-to-centre spacing between retarding stage and output stage, with the ring gear of planet circular system as outfan, reductor can be made to obtain bigger speed reducing ratio, in particular by two output planetary trains as output, can synchronize to drive two cutterheads by both sides, improve work efficiency.
