Abstract
The utility model relates to mechanical engineering machinery, in particular to a reduction box special for a concrete pavement trowelling machine. The reduction box special for the concrete pavement trowelling machine comprises a box body (1), an input shaft (2), a cone-shaped pinion (3), a big sector-shaped gear (4), a middle shaft (5), a middle shaft pinion (6), an output shaft big gear (7) and an output shaft (8). The reduction box special for the concrete pavement trowelling machine is characterized in that the big sector-shaped gear (4) and the middle shaft pinion (6) are arranged on the middle shaft (5), the cone-shaped pinion (3) is meshed with the big sector-shaped gear (4) arranged on the middle shaft (5), and the middle shaft pinion (6) is meshed with the big gear (7) arranged on the output shaft (8). The reduction box special for the concrete pavement trowelling machine has the advantages of being simple in structure, fast in operation, small in motive power loss, long in service life, steady in operation, small in noise, efficient, energy-saving and easy to control in terms of the speed ratio.
Description
Technical field:
The utility model relates to a kind of mechanical engineering machinery, just relates to specifically a kind of concrete road surface polisher special reduction gear.
Background technique:
Speed reducer is one of component commonly used in mechanical industry, the kind of speed reducer is a lot of at present, commonly used have cylindrical gear reducer, conical gear reducer, worm-gear speed reducer, planet-gear speed reducer and a cycloidal pin gear speed reducer etc., although cylindrical gear reducer transmits steadily, efficient is higher, but volume is large, and Gear Processing more complicated, also fragile, the size gear life is inconsistent, small gear is changed frequent, and impact in service and noise are larger, so be not suitable for using on the equipment such as rigid pavement polishing machine.Planet-gear speed reducer and cycloidal pin gear speed reducer structure are complicated, volume is large, and technological requirement is higher, makes general manufacturer without special device be difficult to reach processing request, so manufacture cost is expensive, also be not suitable for using on the equipment such as concrete road surface polisher.And what generally use in concrete road surface polisher at present is worm-gear speed reducer, due to friction eceleration, turn round heavy, tooth surface abrasion is fast, easily heat producing losses's power is larger, and gap and speed ratio are adjusted difficulty, and the center is not on the center line of output shaft, thereby make the easy sideslip of finisher, not easy to operate.
The model utility content:
It is a kind of simple in structure that the purpose of the utility model is to provide, and operates steadily, and energy-efficient, life in application is long, and the speed ratio adjustment is simple, the concrete road surface polisher special reduction gear that noise is low.
For achieving the above object, the utility model can be achieved through the following technical solutions: a kind of concrete road surface polisher special reduction gear comprises casing, input shaft, taper small gear, fan-shaped gearwheel, jack shaft, jack shaft small gear, output shaft gearwheel and output shaft.Be provided with fan-shaped gearwheel and jack shaft small gear on described jack shaft; Described taper small gear and the fan-shaped gearwheel engagement that is arranged on jack shaft; Described jack shaft small gear and the gearwheel engagement that is arranged on output shaft.
The beneficial effects of the utility model are: 1, simple in structure, turn round brisk; 2, kinetic equation loss is little, long service life; 3, operate steadily, noise is low; 4, energy-efficient; 5, the speed ratio size is easily controlled.

2, input shaft
3, taper small gear
4, fan-shaped gearwheel
5, jack shaft
6, jack shaft small gear
7, output shaft gearwheel
8, output shaft
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described: as can be seen from Figure 1, the utility model comprises casing 1, input shaft 2, taper small gear 3, fan-shaped gearwheel 4, jack shaft 5, jack shaft small gear 6, output shaft gearwheel 7 and output shaft 8.Be provided with fan-shaped gearwheel 4 and jack shaft small gear 6 on described jack shaft 5; Described taper small gear 3 and fan-shaped gearwheel 4 engagements that are arranged on jack shaft 5; Make the power on input shaft directly pass to fan-shaped gearwheel 4 by taper small gear 3, due to the small gear 6 that arranges on jack shaft 5 and gearwheel 7 engagements that are arranged on output shaft 8, so transmission efficiency is very high.So structure is very simple, operates steadily, and is energy-efficient, and life in application is long, and reduction speed ratio can realize by the small gear 6 on the change jack shaft and gearwheel 7 sizes on output shaft, so the speed ratio adjusting range is large.All adopt the curved tooth structure due to taper small gear 3 and fan-shaped gearwheel 4 again, so operate steadily, noise is low.
Embodiment: the utility model is arranged on the finisher frame, and input shaft is fixed a belt pulley by key, and belt pulley is connected with motor by belt, and output shaft is fixed on to smear by key and coils upper getting final product.
