Double-row tapered roller bearing clearance adjusting method

Abstract

The invention belongs to the technical field of bearing equipment, and particularly relates to a double-row tapered roller bearing clearance adjusting method, which comprises the following steps of: 1, measuring the sinkage of a roller when the upper row of tapered rollers of a measured bearing are self-locked, and recording the sinkage as delta H; 2, enabling a measurement meter to be in contact with the upper end surface of the inner ring of the middle upper part of the measured bearing, and adjusting the measurement meter to be + delta H; 3, placing the standard space ring between the upper inner ring and the lower inner ring of the tested bearing; 4, rotating the upper inner ring, and recording the reading of the measuring meter as X, wherein X is the actually measured axial clearance of the measured bearing; 5, calculating the actual space ring dimensional tolerance through the formula delta C1C1 = delta C0C0-(X-Ga), wherein the delta C1C1 is the actual space ring dimensional tolerance, the delta C0C0 is the theoretical tolerance of the standard space ring, and the Ga is the standard axial clearance; and 6, machining the space ring product according to the actual dimensional tolerance of the space ring to be assembled into the corresponding bearing. Only sinkage is measured, the axial clearance can be accurately adjusted, time and labor are saved, and efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of bearing equipment and relates to an assembly method of a double-row tapered roller bearing, in particular to a method for adjusting the clearance of a double-row tapered roller bearing. Background technique [0002] Bearing clearance is the gap between the rolling elements of the bearing and the housing of the inner and outer rings of the bearing. The bearing clearance will affect the rolling fatigue life, temperature rise, noise, vibration and other performance of the bearing. Therefore, the bearing clearance data is required when the bearing leaves the factory. Make adjustments and measurements. In the bearing industry for such as figure 1 For the double-row tapered roller bearing shown, the commonly used methods for assembling and adjusting the clearance are measurement method and empirical method. Although the measurement method is accurate, the efficiency is low, and the empirical method is efficie...
