Abstract
The invention relates to the technical field of farm cultivators, in particular to a differential mechanism. The differential mechanism comprises a differential base. A pair of planetary gears are arranged on the differential base. A left output half-axle is arranged at the left end of the differential base, and a right output half-axle is arranged at the right end of the differential base. A left sun gear is arranged at the inner end of the left output half-axle, and a right sun gear is arranged at the inner end of the right output half-axle. The planetary gears are perpendicular to and meshed with the left sun gear and the right sun gear. A differential lock is arranged in the differential base and connected with the left output half-axle. Through connection or disengagement of the differential lock and the left output half-axle, a farm cultivator can move straight or rotate freely by 360 degrees; furthermore, because the differential lock is arranged in the differential base in a built-in mode, the differential mechanism is compact in structure, and the farm cultivator is good in ploughing effect.
Description
Technical field
The invention belongs to agricultural ploughing machine technical field, relate to a kind of differential mechanism.
Background technique
As everyone knows, differential mechanism does not in the market have differential lock mostly, only has fraction differential mechanism to be furnished with the structure of differential lock, and differential lock can be regarded as the differential mechanism with automatic locking function.It can realize the power complete mechanical formula combination of two semiaxis, very firm.Be widely used under severe road conditions or ultimate state.If do not have differential lock, machine cannot carry out freely turning to, and common way is to reverse by force, so relatively require great effort, and inefficiency, and Security is extremely low.Current differential lock is arranged on the two ends of differential mechanism conventionally, and while using on agricultural ploughing machine, the result causing is that arable land effect is bad.
Summary of the invention
For the deficiency existing in background technique, the object of the present invention is to provide a kind of 360 ° of agricultural ploughing machines of allowing rotate freely, the effective differential mechanism of ploughing.
For achieving the above object, the invention provides following technological scheme: a kind of differential mechanism, comprise differential seat, on differential seat, be provided with a pair of planetary pinion, at the left end of differential seat, be provided with left side output axle shaft, right-hand member is provided with right side output axle shaft, the inner that wherein the inner of left side output axle shaft is provided with left sun gear, right side output axle shaft is provided with right sun gear; Described planetary pinion and left sun gear, right sun gear are mutually vertical and intermeshing, in described differential seat, are provided with differential lock, and differential lock is connected with left side output axle shaft.
The right side of above-mentioned left side output axle shaft is provided with connection parent part, and the left side of differential lock is provided with connection bull.
Above-mentioned connection parent part is a groove caving inward, and connecting bull is an outwardly projection, and described groove and protruding sectional shape are quincunx.
The right side of above-mentioned differential lock is provided with spring, and this spring is arranged in differential seat.
One end of above-mentioned differential lock is arranged on the outside of differential seat.
On above-mentioned right side output axle shaft, be provided with umbrella gear.
The present invention's beneficial effect compared to existing technology: the present invention is connected or departs from left side output axle shaft by differential lock, can allow agricultural ploughing machine keep straight on or 360 ° rotate freely, in addition, differential lock of the present invention is built-in, be that differential lock is arranged in differential seat, compact structure, ploughs effective like this.
