Abstract
The utility model discloses a multi-shaft device middle transmission shaft structure which comprises a multi-shaft device box body, a middle shaft, a dual gear and a shaft support. The dual gear is in interference fit with the middle shaft and fixedly connected onto the middle shaft, bearings are arranged at two ends of the middle shaft at the positions close to the end portions, corresponding bearing chambers are arranged in the multi-shaft device box body and the shaft support, and the bearings are in interference fit with the middle shaft and fixedly connected onto the middle shaft. According to the middle transmission shaft structure, machine tool power is transferred to the dual gear through a driving gear and then transferred to an output shaft from the dual gear through a driven gear to achieve power output. The middle shaft is fixedly connected with the dual gear and rotates with the dual gear, the rotating is supported through the bearings at the two ends of the middle shaft, and the middle shaft and the dual gear have no relative movement, so that the middle shaft is not easy to abrade. Butter is added on the bearings to lubricate the bearings, and the middle shaft does not need lubricating, so that the gears can conduct transmission efficiently for a long time.

Model utility content
The purpose of this utility model is the defect for above-mentioned prior art, a kind of intermediate transmission axle construction for multi-shaft device is provided, makes jack shaft produce relative movement, and then guarantee the lubricated of duplicate gear, reduce part wearing and tearing, extend the working life of drilling machine, tapper.
For achieving the above object, the utility model has adopted following technological scheme:
Multi-shaft device intermediate transmission axle construction, comprise multi-shaft device casing, jack shaft, duplicate gear and shaft stool, described duplicate gear and jack shaft interference fit, be fixedly connected on jack shaft, the two ends of described jack shaft are arranging bearing near on the position of end, described multi-shaft device casing, shaft stool are provided with corresponding bearing chamber, and described bearing and jack shaft interference fit, be fixed on jack shaft.
Intermediate transmission axle construction of the present utility model, lathe power is by driving gear transmission to duplicate gear, and duplicate gear passes through driven gear transmission again to output shaft, thereby forms the output of power.Jack shaft and duplicate gear are affixed, revolution together, and by the bearings revolution at jack shaft two ends, jack shaft is just not easy to wear like this, does not need again to lubricate, thereby guarantees that gear is efficient, transmission for a long time.
As the improvement to technique scheme, described shaft stool is arranged on the bottom of multi-shaft device casing, is fixedly connected with multi-shaft device casing by connecting bolt; The bearing chamber of shaft stool connects, and circlip groove is set in bearing chamber, in described circlip groove, back-up ring is set.
As the improvement to technique scheme, described jack shaft hollow, inside be provided with through hole, in described through hole, be installed with lock screw, stretch out from axles box casing and shaft stool at the two ends of lock screw, and the upper end portion of described lock screw arranges locking block, and the end face of multi-shaft device casing arranges corresponding locking slot, described lock screw, locking block connect, and shaft stool and multi-shaft device casing are connected to one.
As the improvement to technique scheme, described bearing is deep groove ball bearing; Or the bearing of the other types such as ball bearing
Compared with prior art, the beneficial effects of the utility model are:
Intermediate transmission axle construction of the present utility model, lathe power is by driving gear transmission to duplicate gear, and duplicate gear passes through driven gear transmission again to output shaft, thereby forms the output of power.Jack shaft and duplicate gear are affixed, and revolution together, by the bearings revolution at jack shaft two ends, jack shaft and duplicate gear are without relative movement, and jack shaft is just not easy to wear like this, and bearing adds butter and keeps lubricated, so jack shaft does not need to lubricate, thereby guarantee that gear is efficient, transmission for a long time.
