Abstract
The invention discloses an agricultural mechanical differential case, which comprises a left casing and a right casing, a cross shaft and two half axle gears , wherein the cross shaft is provided with four planetary gears, the two half axle gears are respectively engaged with the four planetary gears, a power input gear is fixedly arranged on the right casing, the left casing and the right casing are combined into a whole, the cross shaft is arranged in the casings, and lubricating oil holes are respectively formed in the left casing and the right casing. The agricultural mechanical differential case is characterized in that fixing sheets are respectively arranged on four shaft ends of the cross shaft, the fixing sheets are arranged between the inner walls of the casings and the planetary gears, through holes corresponding to the cross shaft are formed in the fixing sheets, and the four shaft ends of the cross shaft respectively pass through the through holes formed in the fixing sheets corresponding to the four shaft ends and are respectively clamped in four shaft holes formed in the casings. The agricultural mechanical differential case has the advantages that the four shaft ends of the cross shaft are respectively and additionally provided with one fixing sheet and are matched with the shaft holes formed in the mechanical differential casing, so that the cross shaft can be completely fixed, the looseness phenomenon cannot occur, the occurrence of accidents is avoided, and the safety is high.
Description
Technical field
The present invention relates to a kind of automotive drive, specifically, relate to a kind of farm machinery differential box.
Background technique
The power transmission of motor drives the driving gear of differential mechanism, Direct driver differential casing, then is delivered to planetary pinion, drives left and right half gear, and then drives wheel.The rotating speed sum of left and right half equals two times of differential casing rotating speed.When its straight line travels, above-mentioned three rotating speeds are identical.When cornering, because automobile stressing conditions changes, feed back in left and right half, and then destroy the original balance of differential mechanism, at this moment rotating speed is redistributed, and causes inboard wheel rotating speed to reduce, and outboard wheels rotating speed increases, and again reaches balance.Meanwhile, vehicle completes turning work.
Be provided with installation four planetary cross axles in differential mechanism, the housing of differential mechanism is provided with four axis holes for fixed cross axle, and four axle heads of inner cross axle are stuck in four axis holes.Find in practice, be only difficult to be fixed cross axle completely by four axis holes on differential casing, after Long-Time Service, cross axle there will be loosening, can be accidents caused time serious, poor stability.
Summary of the invention
The technical problem that will solve of the present invention overcomes above-mentioned defect, provides a kind of and be completely fixed the high farm machinery differential box of cross axle, Security.
For solving the problem, the technical solution adopted in the present invention is:
A kind of farm machinery differential box, comprise left shell, right shell body, four planetary cross axles are installed and are located at two differential gears that the sidewall of left shell, right shell body also engages with four planetary pinions respectively respectively, right shell body is fixedly installed power input gear, left shell and right shell body are in conjunction with as a whole, and cross axle is located in housing; Left shell and right shell body are respectively equipped with oilhole, it is characterized in that: four axle heads of described cross axle are equipped with fixed plate, fixed plate is located between inner walls and planetary pinion, fixed plate is provided with the through hole corresponding with cross axle, four axle heads of cross axle, all through the through hole on the fixed plate corresponding with it, are stuck in four axis holes on housing.
Improvement as technique scheme:
Notch is provided with bottom described fixed plate.
The axis body of described two differential gears is plugged in the mounting hole of left shell, right shell body respectively, is provided with pad between differential gear and inner walls.
Position near differential support end on the sidewall of described left shell, right shell body is equipped with described oilhole, and is respectively provided with 4.
Owing to have employed technique scheme, the present invention has set up a fixed plate respectively at four axle heads of cross axle, and coordinate the axis hole on differential casing, can be completely fixed cross axle, there will not be loosening phenomenon, avoid the generation of accident, Security is high; In addition, set up pad at two between differential gear and inner walls, avoid the direct friction of differential gear and inner walls, increase the service life.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
