It is also understood that it is intended to fix the shaft. There are many types of bearings, among which ball bearings are the most common, and during the use of the ball bearings, there may be a case where the outermost layer of the pressing retainer ring sinks due to external force or radial vibration.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects in the prior art, the utility model aims to provide a retainer ring clamp spring anti-sinking device. The clamping grooves are formed in the two ends of the outer diameter of the bearing inner ring body, the anti-sinking snap springs are additionally arranged in the clamping grooves, so that the platform protruding out of the anti-sinking snap springs blocks the sinking path of the dustproof check ring, and the problem that the outermost layer of the stamping check ring sinks due to external stress or radial vibration in the using process of the bearing can be effectively solved. It can effectively reduce the impact force of outside impurity (earth, stone) to the sealing washer in the use, keeps the operational environment stability of inside key sealing member, prevents that inside second way retaining ring from leading to sealed the inefficacy owing to atress or with impurity friction. Tests prove that the sealing ring can effectively protect the integrity and cleanness of the main sealing element inside, effectively block the invasion of impurities to the inside of the bearing, prolong the service life of the inner layer rubber sealing element and further improve the service life of the bearing. The improvement can be directly used on all long inner ring bearings, especially spherical outside surface ball bearings, the processing difficulty is low, the process is simple, the size and the strength of the original bearing material are not changed, the batch production can reduce the processing period, and the effects of energy conservation and efficiency improvement are realized.

In order to achieve the purpose, the utility model adopts the following technical scheme: the utility model provides a retaining ring jump ring prevents sinking device, includes bearing inner race, bearing inner race and with both complex balls, has set up the draw-in groove at the both ends of bearing inner race body external diameter install additional in the draw-in groove and prevent sinking the jump ring prevent sinking the outer lane of jump ring installs additional the punching press retaining ring.

Preferably, the clamping groove is a square clamping groove.

Preferably, the width of the square clamping groove is 0.8-1.0 MM.

Preferably, a sealing device is further arranged between the bearing inner ring and the bearing outer ring and inside the anti-sinking snap spring.

Preferably, the sealing device is a three-lip sealing sheet.

The working principle is as follows: the processing technical process for preventing the outer retainer ring of the outer spherical ball bearing from sinking comprises the following steps:

step 1: firstly, performing conventional rough and finish turning on a forging;

step 2: turning two 0.8-1.0 MM square clamping grooves at two sides of a raceway of a bearing inner ring turning workpiece body;

and step 3: heat treatment of bearing parts;

and 4, step 4: grinding the end face of the bearing inner ring body;

and 5: rough grinding, fine grinding and ultra-precision grinding of the bearing raceway, the outer diameter and the inner hole;

step 6: the two clamping grooves on the outer diameter of the inner ring body are finely turned, and the original width is not changed;

and 7: matching the bearing inner ring, the bearing outer ring and the balls, and installing a first sealing ring;

and 8: and a customized anti-sinking snap spring is arranged on the square clamping groove in the outer diameter of the inner ring body, and an outermost stamping check ring is arranged.

The utility model has the following beneficial effects:

the utility model improves the structure that clamping grooves are formed in two ends of the outer diameter of the bearing inner ring body, anti-sinking snap springs are additionally arranged in the clamping grooves, so that a platform with the protruding anti-sinking snap springs blocks a sinking path of the dustproof check ring, and the problem that the outermost layer of the stamping check ring sinks due to external stress or radial vibration in the using process of the bearing can be effectively solved. It can effectively reduce the impact force of outside impurity (earth, stone) to the sealing washer in the use, keeps the operational environment stability of inside key sealing member, prevents that inside second way retaining ring from leading to sealed the inefficacy owing to atress or with impurity friction. Tests prove that the sealing ring can effectively protect the integrity and cleanness of the main sealing element inside, effectively block the invasion of impurities to the inside of the bearing, prolong the service life of the inner layer rubber sealing element and further improve the service life of the bearing. The improvement can be directly used on all long inner ring bearings, especially spherical outside surface ball bearings, the processing difficulty is low, the process is simple, the size and the strength of the original bearing material are not changed, the batch production can reduce the processing period, and the effects of energy conservation and efficiency improvement are realized.
