The utility model is designed aiming at the trend that the road roller develops towards large tonnage, has the excellent performances of bearing high load and large torque, has compact structure, smooth operation and convenient gear shifting and gear changing, greatly improves the operability and the comfortableness.
Description
Technical field
The utility model belongs to engineering machinery field, relates in particular to a kind of road roller speed change gear.
Background technique
At present, domestic road roller exists that tonnage is little, the moment of torsion of gearbox is little, can not bear high capacity, the transmission shakiness, vibratory impulse, noise are big, and have problem such as shifted inconvenience, because road roller develops to the large-tonnage direction in recent years, the large roller of import has the load of bearing height, the superior function that moment of torsion is big.But because the price height, complex structure is not suitable for penetration and promotion.
Summary of the invention
In order to address the above problem, the purpose of this utility model provides a kind of road roller speed change gear, has stable drive, and speed ratio is accurate, and is easy to operate, and speed change is steady, impact little, the superior function that noise is little, and prolonged life-span of gearbox effectively.
For achieving the above object, the utility model has adopted following technological scheme:
A kind of road roller speed change gear, have gear, fall along changement, gear mechanism and casing, the gear that is provided with in the described casing has high, medium and low three speed driving mechanisms, be provided with the gear mechanism of gear conversion between described three speed driving mechanisms, be provided with falling of advancing or fall back between described three speed driving mechanisms along changement; The high speed of described gear, in, underneath drive mechanism, two shaftgears on the input gear that is provided with on the input shaft by transferring power and two are connected with a joggle; Fast gear, two-speed gear and three-speed gear on described two respectively with output shaft on be provided with output one fast gear, output two-speed gear and output three-speed gear be connected with a joggle; Described fall goes up two shaftgears that are provided with along changement by two and is connected with a joggle with tumbler gear by the engagement cover, tumbler gear with fall along the bidentate wheel that is provided with on the converting mechanism reversing shaft formation that is connected with a joggle.
A kind of road roller speed change gear that the utility model proposes develops and special development and Design to the large-tonnage direction at road roller in recent years.This novel gearbox adopts the planetary pinion drive mechanism, has the high capacity of bearing, the superior function of high pulling torque.Rational mechanism design, compact structure, smooth operation, shifted convenience has improved operability, travelling comfort greatly.Have stable drive, speed ratio is accurate, and is easy to operate, and speed change is steady, impact little, the superior function that noise is little, and prolonged life-span of gearbox effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1: 1, input shaft, 2, gear, 3, fall, 4, the engagement cover, 5, two shaftgears, 6, two, 7, tumbler gear, 8, output shaft, 9, one fast gear, 10, two-speed gear, 11, three-speed gear along mechanism.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1: a kind of road roller speed change gear, for each third gear six speed of front and back are fallen along speed change, comprise: gear, suitable changement, gear mechanism and casing, be provided with gear in the described casing, described gear comprises: operating rate is set to a speed driving mechanism, work and travelling speed are set to two speed driving mechanisms, and travelling speed is set to three speed driving mechanisms; Being described gear is connected with a joggle by two shaftgears 5 on the gear 2 that is provided with on the input shaft 1 of described transferring power and two 6; Fast gear 9, two-speed gear 10 and three-speed gear 11 on described two 6 respectively with output shaft 8 on the output one fast gear, output two-speed gear and the output three-speed gear that are provided be connected with a joggle; Conversion between a described speed driving mechanism, two speed driving mechanisms, three speed driving mechanisms is provided with gear mechanism, and described gear mechanism is provided with and realizes the gear change hand lever control of regulating the speed; A described speed driving mechanism, two speed driving mechanisms, three speed driving mechanisms advance or the gear that falls back is provided with down along changement, describedly fall to fall along operating grip control by operation along changement; Described fall is meshing with each other and is connected respectively with between the engagement cover 4 along the gear 5 that is provided with on two 6 of the changements and gear 7, gear 7 with fall being connected with a joggle that suitable operating mechanism cogs; Fall and be set to the bidentate wheel along the gear on the operating mechanism 3.
During work, adjust gear, fall, realize the forward-reverse and the friction speed of machine along changement and gear mechanism along operating grip and gear change hand lever by operation.One speed is operating rate, two-speed hold concurrently work and travelling speed, and three speed are travelling speed.Working procedure: when advancing, described power is by input shaft 1 input tape moving gear 2 and gear 5, after power is reached two 6.Make two rotational axis directions and input shaft rotation direction reverse, the fast gear 9 on power passes through two 6, two-speed gear 10 and three-speed gear 11 change over three kinds of speed through gear mechanism, reach pto 8.When retreating, fall along operating grip by operation, make two shaftgears 5 on two 6 and tumbler gear 7 respectively and the transmission that is meshing with each other between the engagement cover 4, input shaft gear 2 is meshing with each other by the bidentate on reversing shaft wheel and tumbler gear 7 on two, make two rotational axis directions and input shaft rotate direction in the same way, reach the change sense of rotation.
The example of the above only is a preferred embodiments of the present utility model, and unrestricted practical range of the present utility model, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should contain and is placed in the protection domain of the present utility model.
