Worm gear case slip torque test system

Abstract

A worm gear case slip torque test system comprises an installing rack supporting a worm gear case, an output shaft of the worm gear case is connected with one end of an arm of force, and the other end of the arm of force has an arc-shaped surface. The arm of force is contacted with a push rod at the arc-shaped surface, and the contact position of the push rod and the arm of force is circular, so that the contact position of the arm of force and the push rod forms the line contact. The push rod is fixed at the mobile end of a jack, the jack drives to apply an acting force to the arm of force, and the push rod is cylindrical, so that the contact position of the arm of force and the push rod forms the line contact. The advantages of the present invention are that: in the slip torque test system, weights are not needed, but the jack is applied, so that the worm gear case slip torque test system is convenient to operate, and is especially suitable for testing the large torque; the rotation of the arm of force does not influence the length of the actually acting arm of force, and the data is more accurate; the worm gear case slip torque test system is low in manufacturing cost and accurate in result, is convenient to use, and overcomes the defect of testing the slip torque of a conventional land leveler worm gear case on a complete machine.

Description

technical field [0001] The invention relates to a system for testing a worm gear box, in particular to a worm gear box slipping torque testing system for testing a worm gear box slipping torque including a motor grader. Background technique [0002] The worm gear box (referred to as the worm gear box, the same as the full text) is mainly composed of a worm gear and a worm screw. The speed can only be transmitted from the worm gear to the worm gear, but not from the worm gear to the worm screw. This is the reverse self-locking property of the worm gear box. The working device of the grader uses the self-locking property of the worm gear box. When the scraper flattens the material, the reaction force of the scraper acts on the worm gear. The working environment of construction machinery is harsh, and it is hot or cold to work outdoors, and it is normal to work under overload. In order to protect the worm gear box, it is necessary to design a suitable worm gear or add a clutch ...
