Abstract
The utility model relates to a gearbox, which comprises a gearbox body, a connecting sleeve and a transmission shaft, the axes of which are perpendicular to each other, are arranged on the gearbox body, the connecting sleeve is fixed on a large conical gear, and one end of the transmission shaft is positioned in the gearbox body and is provided with a small conical gear which is engaged with the large conical gear. When the gearbox is used, the rear power output shaft of the tractor is inserted in the connecting sleeve, the outer spline of the rear power output shaft of a tractor is matched with the inner spline of the connecting sleeve, the gearbox is fixed on the tractor through a connecting bushing, consequently, the connection is simple and quick, the rear power output shaft of the tractor drives the large conical gear to rotate, the large conical gear drives the small conical gear engaged with the large conical gear to rotate, the small conical gear drives the transmission shaft to rotate, and thereby power is outputted; and since the single-stage conical gear transmission is adopted, the direction of power transmission and the rotation speed are changed, and the power loss is less in the process of power transmission.
Description
Technical field
The utility model relates to a kind of gearbox, specifically, relates to a kind of gearbox that can be connected fast with the tractor rear power output shaft.
Background technique
Gearbox is a kind of gear drive of high speed rotating, gearbox mainly is made up of gear and transmission shaft, gearbox has the following advantages: (1) velocity ratio can change, realize the change of velocity ratio by different gear meshing, thereby change the rotating speed and the torque of output shaft, can realize the different rotating speeds and the output of torque; (2) can change the sense of rotation of outputting power; (3) can realize the output and the interruption of power by the control of clutch.
Because gearbox has above advantage, so gearbox mechanically is widely used various, realize the transmission and the rotating speed of power, the reducing or increase of torque, used gearbox adopts spur gear usually now, helical gear or planetary pinion transmission, though adopt spur gear or helical gear gearbox simple in structure, cost is low, but transmission efficiency is low, and power loss is big, vibration and noise are big, velocity ratio is little, if will obtain big velocity ratio, will increase the physical dimension of driving gear or transmission shaft usually, thereby the physical dimension of gearbox is increased, the manufacture cost of gearbox is raise, adopt the gearbox of planetary pinion transmission, transmission efficiency is higher, power loss is little, vibration and noise are little, and velocity ratio is big, but design loaded down with trivial details, complex structure, the manufacture cost height.
At present, the most structure of using with tractor of speed changer that is applied in the farm machinery is complicated, adopt multistage power transmission, the manufacture cost height, bigger in the loss of power transmission process medium power, when gearbox is connected with the tractor rear power output shaft, need the tractor rear power output shaft be linked to each other with the input shaft of speed changer by coupling usually, Placement is complicated.
The model utility content
Problem to be solved in the utility model is at above problem, the gearbox that provide that a kind of simple in structure, low cost of manufacture, power loss are little, gearbox and tractor rear power output shaft can be connected fast.
For addressing the above problem, the technological scheme that the utility model adopted is: a kind of gearbox, comprise gear housing, described gear housing is provided with orthogonal connecting sleeve of axis and transmission shaft, described connecting sleeve is fixedly connected with large conical gear, and the end that described transmission shaft is positioned at gear housing is provided with the small conical gear that is meshed with large conical gear.
A kind of concrete optimized project, described connecting sleeve is provided with internal spline.
A kind of concrete optimized project, described transmission shaft is provided with belt pulley hub.
A kind of concrete optimized project is fixedly connected with adapter sleeve on the described gear housing.
A kind of concrete optimized project is fixedly connected with end cap on the described gear housing.
A kind of concrete optimized project, described gear housing is provided with oilhole.
The utility model is taked above technological scheme, has the following advantages:
(1) in use, the tractor rear power output shaft is inserted in the adapter sleeve, the tractor rear power output shaft is stretched in the adapter sleeve, external splines on the tractor rear power output shaft is matched with the internal spline of connecting sleeve, by adapter sleeve gearbox is fixedlyed connected with tractor then and get final product, Placement is simple, connects fast.
(2) the tractor rear power output shaft drives the large conical gear rotation, and large conical gear drives the small conical gear that is meshed with it and rotates, and small conical gear drives transmission shaft and rotates, the output of realization power, and this gearbox designs is simple, low cost of manufacture.
(3) owing to adopt the single-stage bevel gear drive, changed the direction and the rotating speed of transmission of power, little in the loss of power transmission process medium power.
