Abstract
The utility model relates to a technical field of transmission shaft especially relates to a derailleur mechanical transmission mechanism's transmission shaft. This kind of derailleur mechanical transmission mechanism's transmission shaft includes oil duct, band pulley, transmission shaft and spline, on the transmission shaft is arranged in to the band pulley, is equipped with the oil duct at the front end of transmission shaft, is equipped with the spline in the rear end of transmission shaft. This kind of derailleur mechanical transmission mechanism's transmission shaft's overall structure is simple, and structure through this kind of transmission shaft has reduced manufacturing cost, has prolonged the life of strap.
Description
Technical field
The utility model relates to a kind of transmission shaft, particularly relates to a kind of transmission shaft of speed changer mechanical transmission mechanism.
Background technique
In the prior art, traditional automatic transmission control is convenient, but complex structure, maintenance difficult, manufacture cost is high.The a set of planetary gears of most employing and a set of driving and driven belt wheel mechanism, as transmission of power, during reverse gear work, because transmitting torque is large, easily cause belt wheel and steel band to skid because side pressure is little, affect steel band and belt wheel working life.
Model utility content
The utility model is intended to address the aforementioned drawbacks, and provides a kind of transmission shaft of speed changer mechanical transmission mechanism.
In order to overcome the defect existed in background technique, the utility model solves the technological scheme that its technical problem adopts: the transmission shaft of this speed changer mechanical transmission mechanism comprises oil duct, belt wheel, transmission shaft and spline, belt wheel is placed on transmission shaft, be provided with oil duct in the front end of transmission shaft, be provided with spline in the rear end of transmission shaft.
According to another embodiment of the present utility model, comprise described oil duct further and be placed in top along transmission shaft symmetrical line.
The beneficial effects of the utility model are: the overall structure of the transmission shaft of this speed changer mechanical transmission mechanism is simple, by the structure of this transmission shaft, reduces manufacture cost, extends the working life of metal tape.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, oil duct, 2, belt wheel, 3, transmission shaft, 4, spline.
Embodiment
Fig. 1 is structural representation of the present utility model, and figure comprises oil duct 1, belt wheel 2, transmission shaft 3 and spline 4, and belt wheel 2 is placed on transmission shaft 3, is provided with oil duct 1 in the front end of transmission shaft 3, is provided with spline 4 in the rear end of transmission shaft 3.Oil duct 1 is placed in the top along transmission shaft 3 symmetrical line.
Mechanical transmission mechanism is made up of three axle two gear one belt wheel transmission groups, three axles are transmission input shaft, transmission shaft, output shaft respectively, two-wheeled is reverse driving gear, reverse gear driven gear respectively, and a belt wheel transmission group is made up of forward gear driving pulley, forward gear driven pulley, steel band.Transmission shaft is as shown in Figure 1 solid shaft, front end is stretched in forward gear clutch bearing hole, as transmission shaft front support, front-end shaft sleeve is equipped with bearing, and key tooth is connected with forward gear clutch inner ring, middle part is the driving wheel of main belt wheels, rear end is loaded on case of transmission by bearing, is transmission shaft rear support, in order to increase its bearing capacity, in driving pulley front end, intermediate support bearing is also housed, axle center has belt wheel oil cylinder hydraulic oil duct.
Overall structure is simple, by the structure of this transmission shaft, reduces manufacture cost, extends the working life of metal tape.
