Description

Technical Field

[0001] The utility model belongs to the technical field of engineering machinery, and in particular relates to an intelligent detection system for measuring the size of an adjusting pad of a wheel hub assembly. Background Art

[0002] Among construction machinery, a motor grader is an earth-moving machine that can be used to build roadbeds, pavements, build slopes, dig ditches, mix pavement mixtures, remove snow, push bulk materials, and maintain dirt and gravel roads. A motor grader uses a scraper installed between the front and rear axles of the machine to level the ground. The scraper can be raised, lowered, tilted, rotated, and extended, giving the motor grader a high degree of flexibility and accuracy. Generally speaking, a motor grader uses an engine-driven hydraulic system to move and rotate the blade up, down, left, and right, thereby achieving ground leveling operations. It can move the scraper blade 6 degrees alone or in combination to adapt to different terrains and construction requirements.

[0003] At present, the front axle of the motor grader has a left hub assembly and a right hub assembly. The parts used in the hubs on both sides are the same, and they are an important part of the motor grader's travel system. The hubs are equipped with tapered roller bearings, and their axial clearance needs to be ensured by adding adjustment pads. The selection efficiency of the adjustment pads directly affects the production efficiency of the front axle assembly, and then affects the production rhythm of the whole machine.

[0004] In the prior art, due to the excessive axial clearance of the tapered roller bearing inside the wheel hub, the front axle shakes violently when the grader is moving, and the bearing wears seriously due to the small clearance. In order to ensure the axial clearance requirements, it is necessary to add washers, and the size of the washers needs to be measured manually. Generally, manual measurements are taken multiple times, and the average is calculated to obtain the size of the adjustment pad. Due to the measurement errors of the depth gauge, the reading errors of the operator, and the calculation errors during the manual measurement process, the measurement data is inaccurate, and the normal use of the wheel hub cannot be guaranteed, resulting in serious wear of the bearing.
