Embodiment Construction

[0031] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0032] Such as figure 1 , figure 2 , image 3 As shown, the spherical roller outer diameter ultra-precision process and tooling, the specific steps are as follows,

[0033] First of all, according to the different diameters, lengths, and arc R sizes of the rollers, after debugging, machine tools of different specifications are selected for superfinishing the workpiece to meet the precision requirements of the rollers. The superfine head of fine mechanism 20, but its principle of work is consistent.

[0034] The second step is to turn on the main power supply and cooling system of the machine tool, and select the "automatic" or "semi-automatic" working state of t...

Abstract

The invention discloses a superfine process for the outer diameter of a spherical roller. The superfine process comprises the following specific steps of: 1, debugging according to the size of a workpiece and selecting machine tool fittings of different specifications; 2, switching on a general power supply of a machine tool and a cooling pump and selecting a working status; 3, adjusting the machine tool and setting parameters thereof; 4, feeding with a blanking cylinder of a feeding / blanking mechanism; 5, driving the roller to rotate with a workpiece transmission mechanism, making an oscillating mechanism oscillate and making a superfine mechanism jump into a processing position; 6, performing rough processing and superfine processing with the superfine mechanism; 7, stopping the superfine mechanism, the oscillating mechanism and the workpiece transmission mechanism; and 8, blanking with the feeding / blanking mechanism. The invention has the advantages: the spherical roller has a long service life; the roughness value is small, the Ra is 0.05 mum after superfine processing, the circular degree is increased by 30 percent and is less than 1 mum, and the corrugation is reduced by 30 percent and is less than 1 mum; and the spherical roller is arranged on an elevator bearing after superfine processing, so that the noise is lowered by 30 percent and meets the user requirement in comparison to the noise before superfine processing.

Description

[0001] technical field [0002] The invention relates to the technical field of part processing, in particular to the field of spherical roller processing technology. Background technique [0003] There are four types of rolling elements used in rolling bearings, namely balls, cylindrical rollers, tapered rollers and spherical rollers. In order to make rolling bearings have good rotation accuracy, low noise, long life and good stability, the rolling elements must be Super-finishing to improve its roundness, surface roughness and waviness to reduce the running noise of the bearing and prolong the service life of the bearing. At present, my country has basically solved the superfinishing of balls, cylindrical rollers and tapered rollers, but has not solved the superfinishing technology of the outer diameter of spherical rollers. At present, domestic spherical rollers can only use light finishing to reduce the roughness value of the roller surface. The thermal stress on the s...
