Abstract
The utility model discloses a transmission gear box which includes a left box body (12), a right box body (13), a main shaft (9), a driven gearwheel (1),a driven pinion (2) and a driven large shaft (3); the driven gearwheel (1) is connected with a large driven bevel gear (4); the driven pinion (2) is connected with a drive small bevel gear (6); the gear of the large driven bevel gear (4) is of a round umbrella shape and a groove (26) is arranged in the center of the large driven bevel gear (4); the gear of the drive small bevel gear (6) is of an umbrella shape which is smaller in the upper and larger in the lower and a groove (27) is arranged in the center of the drive small bevel gear (6). As the bevel gears are adopted in the utility model, the transmission effective rate is increased, the cost is low, the service life is increased, the times for exchanging lubricant are reduced and the pollution is less.
Description
Technical field
The utility model relates to a kind of mechanical transmission structure, especially relates to the matched transfer gear box of a kind of rotary cultivator, loosenning tiller or tiller.
Background technique
Drive mechanism generally adopts pot wheel, pot bar structure between common loosenning tiller pto and the gyroscopic action. and the pot wheel of this structure adopts non-ferrous metal to make, the cost height, working life is short, generally is no more than 100 hours; The effective rate variance of transmission; Safeguard inconvenient; Oil change frequency height more; Easy befouling environment.Therefore, the technician thirsts for and can be improved prior art, to overcome the deficiency that prior art exists.
The model utility content
In order to overcome the deficiency that existing above-mentioned all kinds of machineries adopt pot wheel, pot bar structure to exist, the utility model provides a kind of transfer gear box that adopts the common bevel gear drive mechanism.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of transfer gear box comprises left box body 12, right case 13, driving shaft 9, passive gearwheel 1, driven pinion 2 and passive macro-axis 3; It is characterized in that: described passive gearwheel 1 is connected with a driving large bevel gear 4, and driven pinion 2 is connected with a driving bevel pinion 6; Drive large bevel gear 4 gears for circle umbrella shape shape, be provided with a groove 26 at the center; The gear of driving bevel pinion 6 is a up-small and down-big umbrella shape, is provided with a groove 27 at the center.
The beneficial effects of the utility model are, owing to adopted umbrella gear, the efficient increase of transmission, cost is low, and increase working life, and more the oil change number of times reduces, and pollutes little.
Description of drawings
For ease of understanding the utility model, the utility model is described further below in conjunction with accompanying drawing.
Fig. 1 is an internal explosion structural representation of the present utility model;
Fig. 2 is the gear structure schematic representation of driving bevel pinion 6;
Fig. 3 is the gear structure schematic representation that drives large bevel gear 4.
Embodiment
A kind of transfer gear box as shown in Figure 1 comprises left box body 12, right case 13, driving shaft 9, passive gearwheel 1, driven pinion 2 and passive macro-axis 3; It is characterized in that: described passive gearwheel 1 is connected with a driving large bevel gear 4, and driven pinion 2 is connected with a driving bevel pinion 6; Driving large bevel gear 4 gears is a round umbrella shape shape, is provided with a groove 26 at the center; The gear of driving bevel pinion 6 is up-small and down-big one by one umbrella shape, is provided with a groove 27 at the center; Thereby driving bevel gear/axle drive driven gear/axle makes main drive shaft work, reaches the also function of transmission of slowing down.
Claims (3)
1, a kind of transfer gear box comprises left box body (12), right case (13), driving shaft (9), passive gearwheel (1), driven pinion (2) and passive macro-axis (3); It is characterized in that: described passive gearwheel (1) is connected with a driving large bevel gear (4), and driven pinion (2) is connected with a driving bevel pinion (6).
2, transfer gear box according to claim 1 is characterized in that: described driving large bevel gear (4) gear is a round umbrella shape shape, is provided with a groove (26) at the center.
