Embodiment Construction

[0026] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom that are mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words " "Inside" and "outside" respectively refer to the direction toward or away from the geometric center of a specific component. They are relative concepts, so they may change accordingly according to their different positions and different usage states. Accordingly, these or other directional terms should not be construed as limiting terms.

[0027] like figure 1 As shown, the transmission lubrication performance test method provided by the present invention is used to test the lubrication performance of at least one transmission component 2 in the transmission, comprising the following steps: S1: assemble the transmission, at least one transmission component 2 is arranged on the transmission case body 1, and make the transmission case 1 transpar...

Abstract

The invention discloses a gearbox lubricating property testing method and a gearbox lubricating property testing device. The gearbox lubricating property testing method comprises the following steps that a gearbox is assembled, a speed changing component is arranged in a gearbox shell, and the gearbox shell is made to be transparent; the gearbox is placed on a test bench, lubricating oil is addedinto the gearbox shell, and the gearbox is started; the gearbox is adjusted to a specific posture, rotating speed and gear through the test bench, and the lubrication state of a speed change part is observed and recorded; and the posture, the rotating speed and the gear of the gearbox are adjusted, and the lubrication state of the speed change part under different working conditions are observed and recorded. The gearbox lubricating property testing device comprises the speed changing component and the gearbox shell, the gearbox shell is arranged in a transparent mode, and the speed changing component is arranged in the gearbox shell. The gearbox lubricating property testing method and the gearbox lubricating property testing device provided by the invention have the advantage that the lubricating condition of lubricating oil on each part in the gearbox is effectively tested.

Description

technical field [0001] The invention relates to the technical field of transmission testing, in particular to a transmission lubrication performance testing method and testing device. Background technique [0002] The transmission is the core component of the vehicle for mechanical power conversion. The situation in the actual use of the vehicle is more complicated: starting, idling stop, low or high speed driving, acceleration, deceleration, climbing and reversing, etc. Each of the above states has a different transmission ratio, and the internal gears of the gearbox are constantly switching. It is required that the gearbox has good reliability. [0003] In the prior art, during the operation of the transmission, there is heat generated by friction between the friction pairs, and poor lubrication causes excessive temperature, which is easy to ablate the parts, and in severe cases, the function of the transmission is lost. Therefore, it is necessary to test the performance...
