Embodiment Construction

[0037] Step 1: Install the outer ring of the lower bearing into the bearing seat, and check with a feeler gauge to confirm that the bottom surface of the outer ring of the lower bearing fits the bearing seat;

[0038] Step 2: Install both the inner ring of the lower bearing and the inner ring of the upper bearing on the shaft, and check with a feeler gauge to confirm that the inner ring of the lower bearing and the inner ring of the upper bearing are in contact with the corresponding shaft surface on the shaft;

[0039] Step 3: Insert the shaft into the bearing seat, the inner ring of the lower bearing falls into the outer ring of the lower bearing, tap the upper end face of the shaft and rotate the shaft several times;

[0040] Step 4: Install the outer ring of the upper bearing, and the installation depth should ensure that the gap between the outer ring of the upper bearing and the inner ring of the upper bearing is small;

[0041] Step 5: Gradually apply increasing loads t...

Abstract

The invention provides a conical bearing clearance detecting and adjusting method. The method aims to solve the technical problem that the fitting positions of conical bearings can be hardly sought out accurately. According to the method, the fitting points of inner rings and outer rings of conical bearings can be sought out more accurately by acquiring the changing curve of the mounting depth ofthe upper bearing outer ring along with the applied load value and the changing curve of the idle torque of a shaft along with the applied load value, and the clearance adjustment accuracy can be improved.

Description

technical field [0001] The invention relates to a method for detecting and adjusting the gap of a tapered bearing. Background technique [0002] Tapered bearings are widely used in various mechanical structures and are generally used in pairs. During the assembly process, it is necessary to ensure the axial clearance of a pair of bearing inner rings in the outer rings on both sides. The axial clearance is determined by the use conditions of the tapered bearing. If the shaft If the axial clearance is too small, the bearing will burn, and if the axial clearance is too large, it will cause vibration, noise, and early damage. Therefore, whether the axial clearance adjustment is appropriate will directly affect the performance and reliability of the tapered bearing. [0003] At present, the common method of adjusting the gap of the tapered bearing is: measure the thickness of the adjusting pad required when the gap of the tapered bearing is zero, and subtract the gap value from t...
