A kind of bearing steel ball surface strengthening processing equipment

Abstract

The invention discloses a surface strengthening processing equipment for bearing steel balls, which includes a bottom plate, a strengthening processing device and a reciprocating swing mechanism. There are two rollers parallel to the horizontal rotating shaft between the driven turntable and the driving roller shaft between each said roller and the driving turntable, and a slave roller between each said roller and the driven turntable The driving roller shaft, a planetary transmission mechanism is arranged between the horizontal rotating shaft and the driving roller shaft, and the planetary transmission mechanism includes a first driving gear, a second driven gear and a transmission gear assembly, and the transmission gear assembly includes a transmission shaft, The first driven gear and the second driving gear. The equipment can not only increase the strengthening processing rate of the bearing steel ball, but also ensure the consistency of the strengthening processing of the bearing steel ball, the bearing steel ball and the bearing steel ball itself.

Description

technical field [0001] The invention relates to the technical field of strengthening processing of bearing steel balls, in particular to a surface strengthening processing equipment of bearing steel balls. Background technique [0002] Bearing steel ball is a kind of parts used in industrial production, which belongs to the most critical parts in bearings. Its geometric parameters and physical properties directly affect the performance, level, quality and reliability of bearings. In terms of material properties, in addition to the basic requirements of bearing steel such as "high contact fatigue strength, high wear resistance, high elastic limit, and high hardness", the most important requirement is that the surface of the bearing steel ball The consistency of the material of each point and the consistency of the material between the bearing steel ball and the bearing steel ball. In terms of mechanical characteristics, the bearing steel ball is in point contact, so the cont...

AI Technical Summary

Problems solved by technology

If the rotating speed of the drum is too high, even if a rotating rotating plate is added in the middle of the drum, the bearing steel balls will cling to the inner wall of the drum under the action of centrifugal force, and the bearing steel balls will not fall down when reaching the highest point of the drum , thus affecting the strengthening processing efficiency

At present, the larger bearing steel balls in the drum can only be strengthened by the impact generated by the fall of their own weight, while the smaller bearing steel balls can be strengthened by the impact of several hitting rotating plates rotating in the middle on the bearing steel balls. Strengthening, but this kind of impact does not involve all the impact balls and rotating plates at the same time, but impacts the bearing steel balls one by one on a single plate to affect the strengthening efficiency

In addition, this kind of single-drum strengthening will affect the processing efficiency due to the limited capacity, so the strengthening time usually takes more than 4 hours

[0005] 2. The consistency of intensive processing is not high

The impact of each single plate on the bearing steel ball will not only affect the strengthening processing efficiency, but also affect the consistency of the bearing steel ball strengthening process. More impact cycles on the surface of the bearing steel ball are required to ensure the consistency of the bearing steel ball; In addition, due to the use of single-roller strengthening, the amount of bearing steel balls strengthened at one time is limited. It is easy to produce differences due to crushing loads, etc., which makes the consistency of bearing steel ball reinforcement poor
