Problems solved by technology

It realizes the mechanized automatic measurement of bearing clearance through technical means, avoiding human error during manual measurement. However, since the bearing is always in a static state during measurement, only the clearance data of the bearing in a static state can be obtained, which is no longer sufficient. The current production requirements of the automobile engine industry

Abstract

The invention discloses an engine bearing play detection apparatus and measuring method. The apparatus includes a base and a first support and a second support arranged on the base, the first supportis provided with a clamp used for clamping a bearing, the second support is provided with a positioning mechanism, and the base is provided with a displacement mechanism and a measurement mechanism. According to the engine bearing play detection apparatus and measuring method, the engine bearing play detection apparatus is provided, the to-be-detected bearing can be rapidly clamped and located, and the axial play of the bearing in a rotation state is measured; and the to-be-detected bearing is clamped through a pneumatic clamp, the clamping is convenient, the connection of the bearing and a power source is realized by employing a tensioning rod after completion of clamping, an inner ring of the bearing can be driven to rotate through a motor, an outer ring of the bearing is fixed, and theoperating condition of the bearing during practical operation is completely simulated.

Description

Technical field [0001] The invention belongs to the technical field of engine component detection equipment, in particular to an engine bearing clearance detection device and a measuring method. Background technique [0002] Bearings are an important part of contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearing clearance is also called bearing clearance. The so-called bearing clearance refers to the amount of movement when the bearing is not installed on the shaft or the bearing box, the inner ring or outer ring is fixed, and then the bearing clearance is not fixed to move radially or axially . According to the direction of movement, it can be divided into radial clearance and axial clearance. The size of the clearance during operation has an impact on the bearing's rolling fatigue life, temperature rise, noise, vibration and other prope...
