Abstract
The utility model relates to a horizontal nine-axle hand tractor gearbox body which is applicable to a high-power (11.03KW) horizontal nine-axle hand tractor. The gearbox body provided by the utility model is designed according to a nine axle hole structure, wherein, a first axle hole, a second axle hole and a third axle hole are variable-speed axle holes, a fourth axle hole is a steering axle hole, a fifth axle hole is an intermediate axle hole, a sixth axle hole is an output axle hole, a seventh axle hole is a reversing axle hole, an eighth axle hole is the output axle hole of a matching farm implement, a ninth axle hole is the wheelbase stepless regulation hole of a driving wheel, and the first axle hole to the eighth axle hole implement power transmission by a straight-tooth cylindrical gear. The transmission form of the gearbox body is (3+1) x 2, the gearbox body has six advance steps and two backward steps, and each axle hole of the gearbox body is in the horizontal arrangement. Adopting the structures, the utility model improves the stability of the whole machine and the operational reliability and adaptability of the gearbox body.
Description
Technical field
The utility model relates to a kind of horizontal nine hand tractor gearbox casings, belongs to mechanical field.
Background technique
At present, in China hand tractor field, the application of high-power hand tractor more and more widely, three provinces especially northeastward, use the high-power hand tractor of power mostly as 11.03KW, the following dual mode of the many employings of existing its gearbox casing of type, a kind of for adopting final drive gear to reach the seven shaft type gearbox casings that increase the crack, ground, another kind is the arc oblique-horizontal type eight shaft gearbox bodies of no final drive gear, above-mentioned two kinds of gearbox casings exist respectively structural strength poor, the crack little, be unfavorable for the defective of intertilling.Because the narrow limitation of former gearbox casing project organization has caused hand tractor complete machine structure intensity difference, poor reliability is unfavorable for intertillage, easily causes the damage of machine and the damage of crops.
Summary of the invention
The purpose of this utility model is to provide a kind of high-power (11.03KW) horizontal nine hand tractor gearbox casings that are applicable to, the utility model gearbox casing is by nine axis hole structural designs, first, second, the 3rd is the transmission system gear shift axis hole, the 4th for turning to axis hole, the 5th is the idle wheel axis hole, the 6th is output shaft hole, the 7th is the reverse gear axis hole, the 8th is supporting agricultural machinery and implement output shaft hole, the 9th axis hole is driving wheel wheelspan step-less adjustment hole, first to the 8th by straight toothed spur gear realization transmission of power, each axis hole of gearbox casing is arranged by gear-driven designing requirement, the kind of drive is (3+1) * 2, totally six forward gearss, two backward gears; On complete machine is arranged, increase mechanism because of having adopted final transmission, each axis hole of gearbox casing with the balance of assurance complete machine and suitable height of C.G., has alleviated manipulation strength by horizontal arrangement, improved the stability of complete machine, the 9th axis hole that increases both can step-less adjustment driving wheel wheelspan, can improve the linking intensity of final drive gear again, because the utility model has been taked said structure, has improved the operational safety and the applicability of gearbox casing.
