Abstract

The invention provides a tension force tester of an aviation tire supporting framework, and belongs to the technical field of a tension tester. Four groups of slide ways are fixed on a bottom plate in a cross form, a limiting plate is fixed on the bottom plate at the outer end of every group of slide way, and a tension slide block is placed on every group of slide way; the lower end of the tension supporting arm is hinged with a tension slide block, and the upper end of the tension supporting arm is hinged with a pressing tension disk; a reset spring is placed in the center encircled by four tension supporting arms, the upper end of the reset spring is contacted with the pressing tension disk, and the lower end of the reset spring is contacted with the bottom plate; the pressure sensor is fixed at the upper end of the pressing tension disk, a mandril is arranged at the upper part of the pressure sensor, a groove arranged on an outer curve face of the tension supporting arm is used for placing a tire bead ring. In testing process, four tension supporting arms are evenly stressed towards four sides, the testing result closes to the real value more. The tension force tester can test multiple dimensions of bead rings.

Description

technical field [0001] The invention relates to an aircraft tire load-carrying frame tension testing machine, which belongs to the technical field of tension testing machines. Background technique [0002] Radial tires are usually composed of a carcass layer, a belt layer, a steel ring and rubber, among which the carcass layer, belt layer and steel ring are the skeleton materials of the tire, which bear most of the stress on the pneumatic tire, including the carcass Internal pressure stress and pavement impact stress. The wire ring keeps the tire tightly fixed on the rim and bears various interaction forces between the rim and the tire. Due to the large stress, large radial deformation, and easy damage, the traveler must pass the inspection when it leaves the factory, and it can only leave the factory after passing the test. The steel rings of aviation tires require high steel wire strength, good fatigue resistance and impact resistance. The tension testing machine of the...
