Embodiment Construction

[0006] specific implementation

[0007] The motor and gearbox of the driving part of the testing machine are fixed on the desktop of the test bench; the motor drives the gearbox part through the belt to provide power for the testing machine; the friction clutch has two parts, which are connected by bolts, and the two parts of the friction clutch can be Relatively rotate at a certain angle, rotate and tighten with bolts, so that the position of the contact point of the test gear pair changes; the pivot block assembly box B slides relatively on the light, and under the action of the hydraulic cylinder, the pivot block assembly box A and B The gap between the two test gears decreases, which increases the pressure at the contact point of the teeth of the two test gears to achieve loading; the weight tray is welded to the loading rod; after the test gear is worn, the pivot block assembly box B can rotate around the hinge support; the hydraulic cylinder base passes through The bolts...

Abstract

The invention discloses a plastic gear wear life testing machine for a single support self-compensation loading system. The machine is on the basis of an indirect test principle of a ''discontinuous phase method'', and uses an adjustable composite load loading system. A test gear pivot box is supported by a simple hinge, so as to realize the combination loading of a torque and a bending moment ina dynamic meshing simulation process of a test gear. According to the plastic gear wear life testing machine for the single support self-compensation loading system, the dynamic measurement of gear tooth wear can be completed, and the self-compensation loading function of the testing machine in a gear transmission process can be achieved.

Description

technical field [0001] The invention relates to a plastic gear wear life testing machine with a single-support self-compensating loading system, specifically relates to the meshing transmission process of the gear pair in this study, establishes a self-compensating loading power closed flow system, and realizes the self-compensating loading function of the testing machine during the gear transmission process . Background technique [0002] At present, polymer composite gears are more and more widely used due to their unique properties, such as wear resistance, self-lubrication, small friction coefficient and high impact strength. When the polymer composite gears are engaged in transmission, the meshing teeth will generate friction heat due to the existence of friction. The friction heat generated will cause thermal failure of the polymer composite gears, which will not only reduce the transmission efficiency, but also affect the transmission efficiency. Normal use of the ge...
