Embodiment 1

[0033] Such as figure 1 and figure 2 As shown, a differential gear for improving the lubrication of differential gear bearings includes a differential gear body 1 and a differential gear housing 2, and the differential gear housing 2 is installed away from the side of the differential gear body 1 There is a bearing 3; the differential case 2 is provided with a spiral rib 4, and the setting direction of the spiral rib 4 is determined according to the rotation direction of the differential case 2; the spiral rib 4 is formed from the differential The joint between the differential case 2 and the differential body 1 extends along the outer peripheral surface of the differential case 2 in the direction of the bearing 3; the spiral rib 4 extends from the differential body 1 to The size of the bearing 3 becomes smaller gradually.

[0034] This differential increases the feature of the spiral rib 4 on the differential case to ensure that when the differential rotates, the spiral ri...

Embodiment 2

[0047] The difference between this embodiment and the first embodiment lies in that the connection mode of the spiral ribs is different.

[0048] Specifically, the spiral rib 4 is integrally formed on the differential case 2 by casting, forging or 3D printing. Adopting the way of integral molding with the differential case 2 is conducive to improving connection and fixing strength and improving stability.

Embodiment 3

[0050] This embodiment provides a lubrication method for improving the lubrication of differential bearings, the lubrication method includes, when the differential is installed in the gearbox, reduction box or gear box, at a relatively low oil level and low At a rotating speed, the lubricating oil is thrown into the differential bearing on the side where the spiral rib is located by setting the spiral rib on the differential case.

Abstract

The invention discloses a differential gear and a lubricating method for improving the lubrication of differential gear bearings. There are bearings; the differential case is provided with spiral ribs, and the setting direction of the spiral ribs is determined according to the rotation direction of the differential case; the spiral ribs are connected from the differential case to the The joint of the differential body extends along the outer peripheral surface of the differential housing in the direction of the bearing; the spiral rib gradually decreases in size from the differential body to the bearing; the present invention adopts Add spiral ribs to the differential housing, and the spiral ribs can throw the lubricating oil in the box to the bearing on the corresponding side along the direction of rotation of the spiral ribs; without increasing the amount of oil and the active lubrication system, solve the problem Solved the lubrication problem of differential bearings under low speed conditions.

Description

technical field [0001] The invention relates to the technical field of differential gears, in particular to a differential gear and a lubricating method for improving the lubrication of differential gear bearings. Background technique [0002] A vehicle differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. It is mainly composed of left and right side shaft gears, two planetary gears and a gear carrier. When the vehicle is running normally or at high speed, the differential can be continuously lubricated by lubricating oil, and the bearings in the differential housing can also be well lubricated; but when the vehicle is parked or idling for a long time, poor The stalling of the transmission gear causes lubrication failure, so that the lubricating oil attached to the input shaft bearing is starved, and thus, the probability of failure of the input shaft bearing due to insufficient lubrication is likely to i...
