Second row ball filling mechanism of two-row ball bearing

Abstract

The invention provides a second row ball filling mechanism of a two-row ball bearing. The mechanism comprises a lower ball assembly and an assembling base which are arranged up and down, wherein the assembling base comprises a base and a crescent plate; a base is in a circular disc shape with an upward opening; baffling blocks are respectively convexly arranged at the two sides of the circular disc; a pressing block which can be arranged towards a first baffling block and can move parallel to the disc face of the base is arranged at the outer part of a second baffling block; the opening is internally provided with one crescent plate; a bottom plate of the crescent plate is in a circular sheet shape; a crescent-shaped lug boss which protrudes along the outer edge is arranged at one side, which is close to the second baffling block, of the bottom plate; the lower ball assembly comprises a supporting frame which can move along a pressing direction of the pressing block, and a lower ball nozzle and a positioning core which are mounted on the supporting frame; the opening of the lower ball nozzle is arranged downwards; the positioning core is in a column shape which downwards stretches out. When the device can be horizontally placed on inner and outer rings, the second row of the balls are subjected to automatic ball filling work, so that the working efficiency is high; therefore, the contact angle between the two rows of the assembled balls can sufficiently meet standard requirements; an erroneous utilization phenomenon of steel balls is avoided and the fitting success rate of finished products is guaranteed.

Description

technical field [0001] The invention relates to a double-row ball bearing, in particular to a combined sleeve of the double-row ball bearing. Background technique [0002] Double row ball bearings are suitable for applications in bearing arrangements where the load capacity of a single row ball bearing is insufficient. In the case of the same diameter of the inner and outer rings of the bearing, compared with the single row ball bearing, the width of the double row ball bearing is larger, so the load capacity is also much higher than that of the single row ball bearing. [0003] The basic requirement for rolling bearing assembly is to maximize the matching rate under the premise of ensuring the assembly quality index. The so-called matching refers to the premise of fully considering the processing errors of the inner and outer rings and balls of each bearing of the same type. According to the design clearance of the ball in the raceway, select the appropriate bearing inner ...

AI Technical Summary

Problems solved by technology

[0004] At present, the ball loading method of double row ball bearing products generally adopts manual ball loading operation when the inner and outer rings are placed horizontally or machine ball loading operation when the inner and outer rings are placed vertically. The steel balls are easy to mix with the second row of steel balls. It is difficult to avoid the wrong use of artificially selected steel balls, and the ball loading efficiency is relatively low. The latter will change the contact angle of the balls during the ball loading process and affect the quality of the finished product.
