Embodiment Construction

[0016] A method for measuring the central diameter and angle of a solid cage of a spherical roller bearing, characterized in that the method includes the following steps: firstly process and manufacture a central measuring die, the central measuring die is a conical measuring die body 2 and a roller 1, and the central measuring die is The diameter of the roller in the measuring mold is the minimum value of the measured pocket. The upper difference of the diameter tolerance is 0, the lower difference is -0.01mm, and the angle tolerance is ±3′. -0.3mm; the measuring die body 2 in the central measuring die is conical, and the diameter of its small head is D, which is passed by the formula D=D cp -d / Cosβ-2×a×tgβ can be obtained, the diameter of the big head is D1, which can be obtained by the formula D1=D+2×B C ×tgβ can be obtained, the cone height of the cone is H, which is passed by the formula H=B C +a can be obtained, where: Dcp is the center diameter of the product drawing o...

Abstract

The invention relates to a test way of bearing entity holder center drive and angle, particularly relates to the test way of a sphere roller bearing entity holder center drive and the angle. Its characteristic lies in the method including the following steps: first mash and process the center die, the center die is conical die form and roller; then put said three rollers into any three cage ball pockets of tested sphere roller bearing entity. Observing the match condition between said rollers' outside surface and said die form's circular conical surface shows whether the holder center drive and angle of tested sphere roller bearing entity satisfies the designing requirement. The invention's test way is simple, feasible, and test accuracy is high, defective index is low.

Description

technical field [0001] The invention relates to a method for measuring the center diameter and angle of a solid cage of a bearing, in particular to a method for measuring the center diameter and angle of a solid cage of a spherical roller bearing. Background technique [0002] There are two types of existing spherical roller bearing solid cage structures, which are divided into half cages and integral cages. The center diameter and angle measurement methods mainly include the following two types: [0003] 1) Using the finished product assembly method: This method is to select and match the bearing outer ring, bearing inner ring, and rolling elements that match the processed cage, and measure the clearance, and then use the processed cage for assembly. After assembly, check the rotation flexibility and self-aligning performance of the finished bearing to determine whether the cage is qualified. Every time this measurement method is measured, the assembled bearing has to be d...
