Needle bearing assembly machine

Abstract

The invention relates to the field of needle bearings, and specifically discloses a needle bearing assembly machine. The needle bearing assembly machine comprises a needle assembling machine main body, a limiting mechanism, a rotating mechanism, a solenoid valve, a cleaning mechanism, a hydraulic cylinder and a needle omission preventing mechanism; the cleaning mechanism is fixed at the limiting mechanism and the needle assembling machine main body, by the cleaning mechanism, a cavity between a limiting block and the needle assembling machine main body can be kept clean, thus, placing of roller needles is facilitated, arrangement of the roller needles is facilitated, and the roller needles are helped to be mounted in a bearing shell; the needle omission preventing mechanism is in sliding connection with the limiting mechanism and the needle assembling machine main body, and is electrically connected with a solenoid valve, thus, through the needle omission preventing mechanism, openingand closing of the solenoid valve are controlled through weight of the roller needles, reduction of occurrence of a phenomenon of needle missing is facilitated, assembling of the roller needles is facilitated, and assembling of a needle bearing is helped.

Description

technical field [0001] The invention relates to the field of needle roller bearings, in particular to a needle roller bearing assembly machine. Background technique [0002] Needle roller bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. Such rollers are called needle rollers. Although it has a small cross-section, the bearing still has a high load-bearing capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D≤5mm, L / D≥2.5, L is the length of the roller), so The radial structure is compact, and when the inner diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, especially suitable for support structures with limited radial installation dimensions; depending on the application, bearings without inner rings or needle rollers can be selected And the cage assembly, at this time, the journal surface and the housing hole surface matc...

AI Technical Summary

Problems solved by technology

[0003] When assembling the needle roller bearing, the needle roller will be installed on the housing by using the needle loading machine, but when the existing needle loading machine is used, there will be a phenomenon of fewer needles, which requires rework, which is very time-consuming and laborious. It is convenient for bearing installation; and when the needle roller is put into the groove of the needle loading machine, the dirt on the surface of the needle roller will be contaminated into the groove of the needle loading machine. Once the dirt accumulates, the space in the groove will be reduced , which is not conducive to the insertion of the needle
