Description
Technical Field
The utility model relates to the field of automobile hub bearings, in particular to a hub bearing air tightness detection device.
Background
At present, with the development of the automobile industry, automobile manufacturers have higher and higher requirements on the service life of automobiles, wheel hub bearings belong to safety parts and vulnerable parts of automobile parts, and the damage of the wheel hub bearings is generally caused by the fact that muddy water enters the inside of the bearings to finally lose efficacy, so that the sealing performance of the wheel hub bearings is of great importance. When wheel hub bearing assembly for car is produced to general batch, need carry out mud sealing performance test to wheel hub bearing earlier stage, the current all adopts the test machine test, places wheel hub bearing in the laboratory machine, carries out the sealing performance that mud splash comes test wheel hub bearing, generally need operate 1 month time at least, wastes time and energy, influences the production progress.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a hub bearing air tightness detection device which is convenient to detect, can see a detection result in real time, is adjusted in real time, accelerates the production progress, and has a simple integral structure and low cost.
The technical scheme adopted by the utility model for solving the technical problem is as follows: a hub bearing airtightness detection device comprises an air inlet pipe, an air pressure valve, an air pressure gauge, a connecting hose and a water tank, wherein the upper part of the water tank is provided with a mounting hole matched with the air inlet pipe; and water is arranged in the water tank, and the water level exceeds the placed hub bearing.
As a further improvement, the bottom of the water tank is provided with a positioning and placing groove matched with the bolt of the hub bearing.
As a further improvement, a bushing and a rubber gasket are further arranged at the joint of the connecting hose and the outer ring.
The utility model has the advantages that the hub bearing is immersed in a water tank filled with water, air pressure enters the bearing through a connecting air pipe on the outer ring of the bearing, the air tightness of the bearing is reflected in a mode of whether bubbles are emitted or not by the sealing rings at two ends of the bearing, and the air pressure is controlled by an air pressure valve and an air pressure gauge. The air tightness detection device has the advantages of ingenious overall design, simple structure and convenience in assembly, and above all, the air tightness of the third-generation hub bearing sealing ring can be detected effectively and accurately in real time.

Detailed Description
As shown in fig. 1 and 2, the hub bearing airtightness detection device comprises an air inlet pipe 1, an air pressure valve 2, a barometer 3, a connecting hose 6 and a water tank 10, wherein the upper part of the water tank 10 is provided with a mounting hole matched with the air inlet pipe 1, the air inlet pipe 1 is fixed with the air pressure valve 2 and the water tank 10 through a nut 4, and two ends of the connecting hose 6 are respectively communicated with the water tank 10 and an outer ring 9 through an air pipe joint 5 and are communicated with the inside of a bearing; and a bush 7 and a rubber gasket 8 are further arranged at the joint of the connecting hose 6 and the outer ring 9. The water tank 10 is provided with water therein, and the water level exceeds the placed hub bearing. And a positioning and placing groove 13 matched with the hub bearing bolt is arranged at the bottom of the water tank 10.
During installation, one end of an air inlet pipe 1 is connected into an air cylinder to be connected with an air source, the other end of the air inlet pipe, an air pressure valve 2 and an air pressure meter 3 are fixed on a water tank 10 through three nuts 4, then two air pipe connectors 5 are respectively installed on the nuts 4 of the water tank end and a lining 7 of an outer ring end, a rubber gasket 8 is installed on the lining 7 and fixed on a hole 9 of a bearing outer ring (a matched hole is drilled in advance on the bearing outer ring 9), finally two ends of a connecting hose 6 are respectively connected onto the two air pipe connectors 5, and water which does not pass through a hub bearing is installed in the water tank 10, so that installation is completed.
During detection, the required air pressure is controlled through the air pressure valve 2 and the air pressure meter 3, and the air tightness of the bearing is reflected in a mode that whether bubbles are generated at the two sealing rings of the bearing sealing ring assembly A11 and the bearing sealing ring assembly B12 or not. The airtightness detection device has the advantages of good self-sealing reliability, simple structure and convenient operation, and above all, can effectively and accurately detect the airtightness of the third-generation hub bearing sealing ring, has high detection efficiency, and completely meets the requirements in use.
