Device and method for testing performance of worm reduction box

Abstract

The invention discloses a device and method for testing performance of a worm reduction box, and the testing device comprises a vertical support, a controller, a driving device, a connecting component, the worm reduction box and a mounting plate, wherein the bottom of the vertical support is fixed on the plane, one end of the driving device is fixed on the vertical support, and the other end of the driving device is connected to the worm reduction box through the connecting component that realizes the intersection of vertical axes of the driving device and the worm reduction box; the worm reduction box is mounted on the mounting plate, and the bottom of the mounting plate is fixed on the plane; the controller controls the driving device to move front and back by an electric signal, and thedriving device realizes, by means of stretching, that the connecting component rotates at the center of the output gear of the worm reduction box, so that the output gear of the worm reduction box moves by means of rotation of axes in the case of no worm gear self-locking force. In the invention, parts such as worm and gear require no independent testing, thereby reducing the test cost.

Description

technical field [0001] The invention relates to a performance test device and method applied to a worm gear reducer, in particular to a worm gear reducer with overload protection and self-locking performance. Background technique [0002] Worm gear gearboxes are widely used in the field of construction machinery. Its main input is driven by a hydraulic motor, and its output is used to drive the slewing mechanism. In the motor grader, the worm gear reducer is mainly used to drive the rotation of the blade. It not only has self-locking performance but also has overload protection performance. In normal work, relying on the self-locking performance of the worm gear to ensure The angle remains unchanged during the thrust process, and at the same time, in order to protect the worm gear, the internal overload protection clutch realizes automatic slipping when the torque reaches the set value. At present, the performance test of the worm gear box basically relies on the industry s...

AI Technical Summary

Problems solved by technology

At present, the performance test of the worm gear box basically relies on the industry standard or refers to the standard of the reducer. The test content only includes no-load running and load performance, overload performance and fatigue life. There is no relevant basis for protecting the overload torque performance of the clutch
