Abstract
The utility model discloses an impact and vibration resistant gear transmission box. The gear transmission box comprises a gear box, an input shaft and an output shaft, wherein a small bevel pinion is mounted on the input shaft, a big bevel pinion is engaged with the small bevel pinion, the big bevel pinion is mounted on the output shaft, and both the small bevel pinion and the big bevel pinion are mounted in the gear box; an input bearing and an output bearing are respectively mounted on the input shaft and the output shaft, the input bearing and the output bearing are respectively sleeved in bearing supports, the bearing supports are symmetrically mounted on two sides of the gear box, and each bearing support is composed of a connecting end of the gear box and a fixing end of a bearing outer ring; and compound resilient layers are arranged between one bearing support and the connecting end of the wheel box and between another bearing support and the fixing end of the bearing outer ring, and penetrate through the entire thickness of the bearing supports.
Description
Technical field
The utility model relates to the traveling driven wheel transmission gearbox of guideway vehicle, particularly a kind of gear of impact resisting vibrating.
Background technology
The driven wheel transmission gearbox of guideway vehicle is existing at home to be used, because gear is directly installed on wheel on the axletree, so beating, the axletree during travelled by vehicle brings very big shock and vibration to gear, cause bearing holdere fracture, gear to damage, cause the gear early failure, badly influence raising and gear service life of running velocity.Along with The development in society and economy, guideway vehicle presents the trend of operation accelerating, and this ability shock-resistant to gear and vibration has proposed new technical requirements.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of gear of impact resisting vibrating, can increase the ability of transmission gear shock resistance and vibration.
The technical solution of the utility model is as follows: a kind of gear of impact resisting vibrating, comprise gear case, input shaft and output shaft, on the described input shaft bevel pinion is installed, mesh large helical gear on the described bevel pinion, described large helical gear is installed on the output shaft, described bevel pinion and large helical gear are installed in the gear case, be separately installed with input bearing and output bearing on described input shaft and the output shaft, described input bearing and output bearing are set in the bearing seat, described bearing seat is installed in described gear case both sides symmetrically, described bearing seat is by forming with gear case coupling end and outside race fixed end, between bearing seat and gear case coupling end and outside race fixed end composite elastic layer is set, described composite elastic body layer runs through the whole thickness of bearing seat.
Adopt technique scheme, the composite elastic body layer is set in bearing seat, with such bearing seat as gear each rotation support, the shock and vibration that gear integral body is born that can absorb or decay of composite elastic body layer improve the whole anti shock and vibration ability of gear from structure.
In technique scheme, the helical angle of described bevel pinion and large helical gear is 20o.Make transmission gear ingear overlap ratio improve 1.64 times, to increase the ability of transmission gear shock resistance and vibration.
In technique scheme, an end of described input shaft is outside bearing seat stretches out gear case, and the other end is positioned at bearing seat, and the two ends of described output shaft are all outside bearing seat stretches out gear case.
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, the shock and vibration that the gear integral body that can absorb or decay is born, from the whole anti shock and vibration ability of structure raising gear, to prolong the work life of gear case and bearing.
