Abstract
The utility model discloses a tractor gearbox planetary reduction gear-reversing device which comprises a transmission shaft, a central gear, an inner gear ring, a planetary gear carrier and an attaching sleeve, wherein the transmission shaft is connected with the power output device of a speed changing mechanism; the central gear is arranged on the transmission shaft; the inner gear ring is fixed to the casing body of the gearbox; the planetary gear carrier is arranged between the central gear and the inner gear ring and is provided with a first planetary gear and a second planetary gear which are engaged with each other; the first planetary gear is engaged with the central gear; the second planetary gear is engaged with the inner gear ring; the attaching sleeve is controlled by a gear position steering mechanism, is connected with a rear axle assembly, and is provided with a neutral position, the gear reversing position which can be connected with the planetary gear carrier and the advancing position which is connected with the transmission shaft. The utility model effectively increases the gear positions of the gear-reversing operation, can better suit to the requirements of various engineering operations, be more reasonably used with various agricultural implements and increase the operation efficiency of tractors.
Description
Technical field
The utility model relates to the gear box of tractor technical field, relates in particular to a kind of reverse gear speed reducer.
Background technique
Known 50～70 horsepowers tractor, the gear that advances is many, be generally 4 or 8, and its reverse gear mechanism adopts generally cylindrical gear pair and secondary speed change or main transformer speed to combine, and 2 or 4 reverse gear gears can only be provided.Because reverse gear gear quantity is few, when supporting frontloader tool, the operating efficiency of tractor obviously reduces, and makes the adaptability variation of tractor.
The model utility content
Technical problem to be solved in the utility model is: a kind of gear box of tractor planetary reduction gear gear reversing device is provided, and it can effectively increase the gear of reverse gear operation, improves the conformability of tractor operation.
For solving the problems of the technologies described above, the technical solution of the utility model is: gear box of tractor planetary reduction gear gear reversing device, comprise the transmission shaft that is connected with the power take-off of gear, be arranged at the sun gear of described transmission shaft, be fixed in the ring gear of gear box casing, be arranged at the planetary wheel carrier between sun gear and the ring gear, described planetary wheel carrier is equipped with intermeshing first planetary pinion and second planetary pinion, described first planetary pinion and sun gear engagement, described second planetary pinion and ring gear engagement; Be subjected to gear operating mechanism control, and can axially movablely articulate cover, described articulate tackling reverse gear position that neutral position is arranged, can be connected and the gear that advances that can be connected with transmission shaft with planetary wheel carrier.
Because first planetary pinion and second planetary pinion are meshing with each other, and first planetary pinion and sun gear engagement, second planetary pinion and ring gear engagement, thus the revolution direction of planetary wheel carrier and the direction of rotation of transmission shaft, and be decelerated.Under the control of gear operating mechanism, articulate and overlap when being in neutral position, gearbox does not have power output; When articulating cover and being connected with planetary wheel carrier, articulate cover and be in the reverse gear position, gearbox realizes that the low speed power that falls back exports; When articulating cover and being connected with transmission shaft, articulate cover and be in the gear that advances, the gearbox power of realizing advancing at utmost speed is exported.Like this, the gear that advances is identical with the reverse gear bit quantity, and its quantity all depends on the speed change quantity of gear.In the ordinary course of things, gear can produce 8 grades of speed, that is to say, adopt structure of the present utility model after, under the situation that other structure need not change, just can export 8 reverse gear gears.Thereby it has effectively increased the gear of reverse gear operation, the conformability of raising tractor operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model embodiment's a structure sectional view.
Embodiment
As shown in drawings, gear box of tractor planetary reduction gear gear reversing device, comprise the transmission shaft 2 that is connected with flip sleeve 11 feather keys of secondary gear 1, be arranged at the sun gear 21 of described transmission shaft 2, be fixed in the ring gear 8 of gear box casing, be arranged at the planetary wheel carrier 5 between sun gear 21 and the ring gear 8, described planetary wheel carrier 5 is equipped with intermeshing first planetary pinion 6 and second planetary pinion 7, described first planetary pinion 6 and sun gear 21 engagements, described second planetary pinion 7 and ring gear 8 engagements; Be subjected to gear operating mechanism 4 control, and can axially movablely articulate cover 3, articulate cover 3 when endwisely slipping, can be connected with planetary wheel carrier 5 feather keys, also can be connected with transmission shaft 2 feather keys, thereby articulate that cover 3 has neutral position, reverse gear position that can be connected with planetary wheel carrier 5 feather keys and the gear that advances that can be connected with transmission shaft 2 feather keys, articulate cover 3 and be connected with rear axle assy, with transmission of power to rear axle assy.
Certainly, transmission shaft 2 also can directly be connected with the power take-off of main speed-changing mechanism.
