Embodiment 2

[0051] Embodiment 2 of the test method for water resistance of sealed deep groove ball bearings of the present invention comprises the following steps: the inner ring of the test bearing is driven to rotate through the transmission shaft outputting the rotational motion, and at the same time, a radial load is applied to the outer ring of the test bearing by a radial loading system. To the load, spray water to the end face of the test bearing through the water spray system at the same time; then test the waterproof performance of the test bearing. During the water spraying process, the temperature of the outer ring of the bearing and the vibration of the bearing are tested through the temperature sensor and the vibration sensor arranged on the outer ring of the test bearing. The radial loading system and the test bearing are fixedly connected through the bearing body sleeved on the outer ring of the bearing. The radial loading system includes, from bottom to top, a pull rod exte...

Embodiment 3

[0052] Embodiment 3 of the waterproof test method of sealed deep groove ball bearings of the present invention is different from the above embodiment of the waterproof test method of sealed deep groove ball bearings in that a test bearing is provided at both ends of the transmission shaft, which can simultaneously Two different bearings were tested for water resistance comparison.

Abstract

The invention relates to the field of bearing test technology, in particular to a sealed deep groove ball bearing waterproofness testing method and a testing device using the testing method. The sealed deep groove ball bearing waterproofness testing method includes the steps of driving an inner ring of a bearing to be tested to rotate through a transmission shaft outputting rotating motion, exerting radial load on an outer ring of the bearing to be tested through a radial loading system, spraying water to an end face of the bearing to be tested through a water spraying system, and then detecting waterproofness of the bearing to be tested. The sealed deep groove ball bearing waterproofness testing method and the testing device can truly simulate rotating speed and loading conditions of the sealed deep groove ball bearing in the actual working process. The water spraying system can be used for spraying water to the end face of the bearing. After the water spraying, the waterproofness of the bearing can be verified and checked through observation of water inflow conditions of the interior of the bearing.

Description

technical field [0001] The invention relates to the technical field of bearing tests, in particular to a waterproof test method of a sealed deep groove ball bearing and a device using the test method. Background technique [0002] Sealed deep groove ball bearings are rolling bearings with sealing rings on one or both sides. They are widely used in various household appliances, engineering machinery, vehicles, ships, aviation and aerospace, weaponry and other fields. The sealing rings on the bearings can prevent external Harmful objects such as dust, moisture, and foreign matter invade the inside of the bearing, making the bearing run safely and permanently. In a sense, the sealing performance of the sealed bearing is more important than the fatigue life. On some supporting hosts, the change of the sealing performance of the sealed bearing can cause the rapid failure and damage of the bearing. [0003] At present, the experimental research on sealed deep groove ball bearings...
