Description
Technical field
The utility model relates to a kind of rice transplanter steering hardware.
Background technology
In the rice transplanter steering hardware between power input shaft and power take-off shaft owing to need to produce certain pendulum angle, therefore adopt universal shaft coupling device to connect between power input shaft and the power take-off shaft usually, and the transmission efficiency of drive coupling reduce greatly with the change of angle between input shaft and the output shaft.When the rice transplanter steering hardware turned to, hard-over reached 70 degree, drive coupling this moment effective transfer of torque often.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, rice transplanter steering hardware that torque transfer efficient is not influenced by deflection angle.
For achieving the above object, the utility model is by the following technical solutions:
Rice transplanter steering hardware described in the utility model comprises by last hinge and the hinged permanent seat of down hinge, steering base, be installed with steering gear on the steering base, pass through the dynamic output shaft of bearing installation on the permanent seat, power take-off shaft is vertical with last hinge, it is characterized in that: down hinge is coaxial with last hinge, be installed with bevel pinion on down hinge or the last hinge, large bevel gear, the takeoff output the tip of the axis is provided with the takeoff output bevel gear, other has the power input shaft with the coaxial setting of power take-off shaft, the end of power input shaft is provided with the power input bevel gear, takeoff output bevel gear and power input bevel gear respectively with large bevel gear, the bevel pinion engagement.
Described steering base is provided with the oil bowl, and described oil bowl is a bowl, and down hinge is positioned at the center of oil bowl.
Described bevel pinion and large bevel gear all are fixedly mounted on the down hinge.
Described bevel pinion and large bevel gear all are fixedly mounted on the hinge.
One of them is fixedly mounted on described bevel pinion and large bevel gear on the down hinge, and another is fixedly mounted on the hinge.
Adopt after the technique scheme, this rice transplanter steering hardware meshes with power input shaft and power take-off shaft respectively by the bevel gear of two captive joints, and its torque transfer efficient has nothing to do with turning to angle, especially is suitable for use on the big rice transplanter of steering angle.

The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Rice transplanter steering hardware described in the utility model comprises by last hinge 8 and down hinge 7 hinged permanent seat 3, steering base 1, be installed with steering gear 2 on the steering base 1, gear mesh on steering gear 2 and the direction machine steering shaft promotes steering bases 1 by steering gear 2 in the time of the axis of orientation rotation and swings back and forth.By the dynamic output shaft 6 of bearing installation, power take-off shaft 6 is vertical with last hinge 8 on the permanent seat 3.Down hinge 7 is coaxial with last hinge 8, is installed with bevel pinion 9, large bevel gear 10 on down hinge 7 and the last hinge 8.Bevel pinion 9 and large bevel gear 10 can be whole being fixedly mounted on the down hinge 7 as shown in Figure 4; Also can be all to be fixedly mounted on as shown in Figure 5 on the hinge 8, certainly, as shown in Figure 4, in order to make its rotation more flexible, the down hinge 7 that bevel pinion 9 and large bevel gear 10 are installed or on hinge bearing 71 can also be set on the hinge 8.End at power take-off shaft 6 is provided with takeoff output bevel gear 61, other has the power input shaft 5 with power take-off shaft 6 coaxial settings, the end of power input shaft 5 is provided with power input bevel gear 51, and takeoff output bevel gear 61 and power input bevel gear 51 mesh with large bevel gear 10, bevel pinion 9 respectively.Power input shaft 5 is used to connect power machines such as driving engine, change speed gear box.Power input shaft 5 can also can not be connected with steering base 1 by bearing installation on steering base 1, and the openwork part that passes on the steering base 1 is connected on the exterior power machine.
Described steering base 1 is provided with oil bowl 19, and described oil bowl 19 is a bowl, and down hinge 7 is positioned at the center of oil bowl 19.In the oil bowl 19 lubricating oil is housed, in work, can plays the effect of lubricated bevel pinion 9 and large bevel gear 10, make turn to more flexible, power transmission efficiency is higher.
The structure and the principle of work of above-mentioned steering base 1, permanent seat 3, steering gear 2 and direction machine are known technology, do not repeat them here.
During use, power machine is connected to power input shaft 5, action actuating mechanism on the rice transplanter is connected on the power take-off shaft 6, mechanical power is delivered to down hinge 7 or goes up hinge 8 by power input shaft 5, power input bevel gear 51, gives takeoff output bevel gear 61 and power take-off shaft 6 through large bevel gear 10, bevel pinion 9 with transmission of power again.When turning to, steering base 1 and the certain angle of power input shaft 5 swings, power input bevel gear 51 with down hinge 7 or the axis of going up hinge 8 be after the center rotates to an angle still with down hinge 7 or go up bevel gear engagement on the hinge 8, realize the smooth transfer of power.
