Abstract
Chain of the utility model design, shaft drive cross box, by angular wheel and principal axis transformation, become chain transmission into shaft drive, reduces the improvement and design expense of former machinery, reduces costs.The utility model is designed with a casing, and inside is provided with input, two axles of output, the output sprocket in former mechanical transmission is installed on input shaft, and angular wheel of parallel installation is on same axle; On output shaft, another bevel gear is installed, mesh with input shaft bevel gear, after original dynamic rotation direction is changed to 90 °, by output shaft outputting power.Cross box housing is made split type, and one end is screwed after being fastened by end cap; The parallel stiffening rib in each face of cross box hull outside Jun You tri-roads, to strengthen its bearing power, prevents fracture; Cross box is connected plane to be made with the axis of pto＝power take-off and is inclined to 77 ° of angles with body, to adapt to the good of planting mechanism moving element after machine, docks.
Description
Technical field
The utility model relates to the transmission of a kind of transplanting machinery chain and driven off by shaft cross box.
Technical background
At present, the power of many transplanting machineries is exported by engine mission, then through chain transmission, power is flowed to the planting mechanism after fuselage, makes its running, realizes the operation of planting.Because chain transmission transmission efficiency is high, cost is low, is easy to Installation and Debugging and maintenance and is extensively used on transplanting machinery.But along with the raising that the progress of Machine Manufacturing Technology and people require transplanting machinery service behaviour, shaft drive with its in mechanical transmission compact structure, durable in use, working service amount is little and progressively replace chain transmission in the past.In order simply and easily chain transmission to be converted to shaft drive, this just needs a conversion equipment, in the situation that other structure is substantially constant, directly chain transmission is become to shaft drive.
Summary of the invention
Chain of the utility model design, shaft drive cross box, by angular wheel and principal axis transformation, become chain transmission into shaft drive, reduces the improvement and design expense of former machinery, reduces costs.The utility model is designed with a casing, and inside is provided with input, two axles of output, the output sprocket in former mechanical transmission is installed on input shaft, and angular wheel of parallel installation is on same axle; On another root output shaft, another bevel gear is installed, mesh with input shaft bevel gear, after original transmission of power direction is changed to 90 °, then outputed power by output shaft.Cross box housing is made split type, and one end is screwed after being fastened by end cap; The parallel stiffening rib in each face of cross box hull outside Jun You tri-roads, to strengthen its bearing capacity, prevents fracture; Be connected plane with body and make with the axis of pto＝power take-off and be inclined to 77 ° of angles, to adapt to and being connected of planting mechanism moving element after machine.
The beneficial effects of the utility model are: for former, be designed to chaindriven machinery, only use a simple conversion equipment, just will be originally that chaindriven machine changes to shaft drive, make transmission become more reliable, durable, compact.

1, sprocket wheel 2, drive bevel gear 3, input shaft 4, driven wheel of differential 5, stiffening rib 6, casing 7, output shaft 10, housing plate.
Embodiment
Below in conjunction with accompanying drawing, this model utility is described further:
The utility model is designed with a transmission conversion casing 6 as the support of all component, input shaft 3 is fixed on casing 6 by bearing with output shaft 7, sprocket wheel 1 is installed on input shaft 3, by sprocket wheel 1, chaindriven power is introduced in conversion casing, input shaft is rotated.Drive bevel gear 2 is also installed on input shaft simultaneously, bevel gear 2 and driven wheel of differential 4 engagements, pass to gear 4 by rotating power by gear 2, due to driven gear 4 and output shaft 7 key fixed connection, thereby power is passed to output shaft 7, complete power and be transferred to shaft drive conversion by chain.Input shaft 3, output shaft 7 two ends are fixed on casing by bearing; For strengthening casing intensity, on casing four sides, be all added with three of parallel gussets; For a change output shaft direction, makes it consistent with the motion power input shaft driving after fuselage, and casing connection in-plane is made as required with the axis of output shaft 7 and is inclined to 77 ° of angles.Casing is made split type, casing 6 and end cap 10, consists of, and end cap 10 is screwed on casing.
Claims (4)
1. chain, a shaft drive cross box, is characterized in that: by a casing, supported, each axial workpiece is fixed thereon.
2. chain as claimed in claim 1, shaft drive cross box, is characterized in that: an input shaft, and an output shaft, both intersect in 90 °.
3. chain claimed in claim 1, shaft drive cross box, is characterized in that: casing outer side surface all has three parallel stiffening ribs.
4. chain as claimed in claim 1, shaft drive cross box, is characterized in that: the connection plane of casing becomes the angle of 77 ° with the shaft axis of output shaft.
