A kind of single-input double-output gearbox, including gear-box case and the gear drive machine being arranged in gear-box case
Structure；It is characterized in that：The gear-box case includes drain pan, upper casing and middle case, wherein, upper casing is relative with middle case to fasten shape
Into driving gear box；The gear drive includes drive bevel gear, driven wheel of differential and input and output jackshaft；It is described defeated
Enter to export jackshaft to be arranged in driving gear box, its top and lower end pass through midship shaft bearing and driving gear box phase respectively
Connect；The drive bevel gear is sleeved on the outer wall of input and output jackshaft lower end, and with input and output jackshaft synchronous axial system；
The driven wheel of differential is arranged on drain pan by driven wheel of differential bearing, and driven wheel of differential is often engaged with drive bevel gear.
Further say, the input and output jackshaft is provided with centre bore, and the section of the centre bore is in regular hexagon；It is described
The outer wall of input and output jackshaft lower end is in positive six prismsby shape, the centre bore of the drive bevel gear be with the middle of input and output
The regular hexagon hole that the lower end outer wall of axle matches.
Further say, the middle case two sides relative with upper casing, drain pan are respectively equipped with positioning jack, it is described on
The positioning inserting column corresponding with positioning jack is respectively arranged with shell, drain pan.
Further say, the drain pan is provided with the bearing block for the circular recess for being used to install driven wheel of differential bearing；Institute
State driven wheel of differential center and be provided with the fastening screw for being used for making driven wheel of differential be fastenedly connected with power output shaft.
Beneficial effect：Compared with prior art, the utility model is the structure design of single-input double-output, in input and output
After countershaft input power, contract can be matched somebody with somebody by the output end and drive bevel gear of input and output jackshaft and driven wheel of differential
When export power in both direction, so as to realize both sides table leg synchronization lifting and lifting is consistent；In addition, of the present utility model
Gear-box case is the split-type structural assembled by three parts, can substantially reduce gearbox research and development mould input cost,
Design risk is reduced, is reduced because Gear Production tolerance causes the quality cost of engagement disqualification rate.Furthermore, when drain pan and middle case
When being assembled, gear engagement elasticity can be debugged, it is too loose then that the mounting plane of middle case mill is low, too tightly then can be
Shimming between drain pan and middle shell.
