Error compensation mechanism of two-side-transmission root-stubble smashing and field returning machine

Abstract

The invention discloses an error compensation mechanism of a two-side-transmission root-stubble smashing and field returning machine. The error compensation mechanism is characterized in that overrun clutch assemblies (3) are installed in transmission devices on the two sides respectively; each overrun clutch assembly (3) comprises a clutch outer ring (12), a clutch inner ring (9) and an annular clutch wedge block (11); the clutch outer rings (12) are of cylindrical gear structures, the clutch inner rings (9) are provided with splines, and the annular clutch wedge blocks (11) are arranged between the clutch outer rings (12) and the clutch inner rings (9); the clutch inner rings (9) are connected with lateral transmission shafts (2) through the splines; gears of the clutch outer ring (12) are engaged with second gears of lateral transmission cases. The error compensation mechanism is simple and compact in structure and large in transmitted power, the assembling position is conveniently adjusted while transmission errors are eliminated, and manufacturing cost is low.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an error compensating mechanism for a root stubble crushing and returning machine or a rotary cultivator driven on both sides. Background technique [0002] With the development of power machinery in our country, the power of tractors is increasing continuously, and the plowing width of the supporting stubble crushing and returning machine or rotary tiller is also increasing. In order to make the stubble crushing and returning machine or rotary tiller work The torque borne by the cutter shaft is more reasonable, and the implement is easier to balance. The stubble crushing and returning machine or rotary cultivator driven on both sides is very popular among farmers and widely used. However, since the power of the working cutter shaft is input from both sides, this requires that the transmission on both sides must be synchronized, otherwise there will be transmission interference, which w...

AI Technical Summary

Problems solved by technology

On both sides of the transmission, errors will occur during the manufacturing and assembly process of parts, especially the transmission error of the gear and the position error of the spline are difficult to eliminate, and it is very difficult to achieve the synchronization error within the allowable range.

[0003] At present, in order to solve this problem, the better method is to use the central differential, but the main disadvantages of this method are bulky, complex structure, high cost, and it is difficult to add a speed change mechanism to the central gearbox

In addition, there is also a gap reserved in the transmission chain for error compensation. This method does not really realize the transmission on both sides, and relies on the side with the smaller gap to transmit power during the transmission process.

Moreover, in the manufacturing process, the relative positions of spline teeth and gear teeth must be unified, otherwise they cannot be assembled correctly, and the interchangeability of parts will also be affected.
