Gear impact fatigue detection device

Abstract

The invention discloses a gear impact fatigue detection device. The gear impact fatigue detection device comprises a workbench, two groups of mounting brackets are fixedly arranged on the workbench, and a driving threaded rod is movably provided with a test gear; an output end of a driving motor is fixedly provided with a rotating shaft, a first connecting rod is fixedly arranged on the rotating shaft through penetration; one end of a connection shaft, far away from a stop dog, is fixed on an impact block; and the impact gear is fixedly arranged at a center of an extension plate; an external side of the rotating shaft is provided with a ring bearing, the ring bearing is movably arranged at the center of a driving gear, and adjusting nuts is arranged at two sides for adjusting a single-tooth gear. The invention provides the gear impact fatigue detection device, in usage, test gear position of he test gear can be automatically and intermittently adjusted, impact times can be counted accurately, reciprocating operation impact of the impact gear can be realized through structures, a motor is free from working intermittently, and thus, the motor is protected effectively, so the gear impact fatigue detection device is very worth being generalized.

Description

Technical field [0001] The invention relates to the technical field of gear detection, in particular to a gear impact fatigue detection device. Background technique [0002] In the prior art, a fatigue test device for a drive disc gear ring with the application number "201710232370.1" includes a drive disc support, a pressure support, a lever, a power device, etc., wherein the drive support is used to vertically fix the drive disc; The pressure support is arranged on one side of the drive plate support, and is connected to the horizontal lever by rotating. One end of the lever exerts a vertical force on the gear ring on the side of the drive plate; the power device exerts a vertical reciprocating force on the other end of the lever. During the test, the power device reciprocates vertically, pressing the lever to rotate in a small amount, and the other end of the lever exerts a reciprocating impact on the ring gear on the side of the drive plate to simulate the actual starting sta...

Problems solved by technology

[0003] However, there are still obvious defects in its use: 1. The above-mentioned device can only repeatedly impact one tooth of the test gear. For the impact test, repeated disassembly and installation are cumbersome; 2. There is no counting structure in the above device, and the number of impacts in the test cannot be accurately calculated, which affects the accuracy of the test results
