Description

A kind of air compressor machine connecting rod special bearing

Technical field

Field of bearings is the utility model is related to, more particularly to a kind of air compressor machine connecting rod special bearing.

Background technology

The connecting rod of air compressor machine will use bearing when in use, because the connecting rod working strength of air compressor machine is bigger, Requirement to bearing is also bigger, and the job stability of bearing ball when work is critically important, the routine of present bearing Retainer has been difficult to meet this needs to work long hours, and long-time high intensity using the requirement to dust cap also very Height, present dust cap sealing effectiveness is bad, easily causes the leakage of grease and the entrance of dust.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of air compressor machine connecting rod special bearing, using special guarantor Frame structure is held, can guarantee that the high intensity steady operation of ball, and using the dust cap connected and fixed, good sealing effect will not Come off, prevent grease leakage.

Technical scheme is used by the utility model solves its technical problem：A kind of air compressor machine connecting rod special axis is provided Hold, including outer ring and inner ring, several balls are evenly equipped between described outer ring and inner ring, are respectively mounted on the outside of described ball Have the retainer being connected, both sides are symmetrically installed with dust cap between described outer ring and inner ring, the dust cap in plane, Several rubber bails are disposed with around even circumferential on the upper inner wall of the dust cap, corresponding outer ring disposed inboard has Step outwardly, T-shaped annular groove corresponding with rubber bail is disposed with the mesa sidewall, the lower end of described dust cap is embedded into In annular groove on inner ring lateral surface, described retainer includes being arranged symmetrically ball is clamped into spacing ring, and described is spacing The upper and lower ends of ring, which cross out, is disposed with location division, and tip protuberant bar is disposed with the location division, and the tip protuberant bar is embedding Enter into V-ring groove corresponding on the madial wall of outer ring, leave gap between described tip protuberant bar and V-ring groove and fill There is lubricant grease, the coefficient of curvature of described inner ring is 0.535.

Preferably, the madial wall of described spacing ring is arcwall face, the shape of the arcwall face and ball match and with rolling An intersegmental gap is left between pearl.

Beneficial effect：A kind of air compressor machine connecting rod special bearing is the utility model is related to, using special retainer structure, energy Ensure the high intensity steady operation of ball, and using the dust cap connected and fixed, good sealing effect, prevent grease leakage, increase Add the inclination angle of bearing, it is stuck when preventing bearing high-speed motion.

Embodiment

With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen Please appended claims limited range.

As shown in Figure 1-2, embodiment of the present utility model is related to a kind of air compressor machine connecting rod special bearing, including outer ring 1 With inner ring 2, several balls 3 are evenly equipped between described outer ring 1 and inner ring 2, the outside of described ball 3 is mounted on being linked to be The retainer 5 of one, both sides are symmetrically installed with dust cap 4 between described outer ring 1 and inner ring 2, the dust cap 4 in plane, On the upper inner wall of the dust cap 4 several rubber bails 8, the corresponding inner side cloth of outer ring 1 are disposed with around even circumferential Step outwardly is equipped with, is disposed with T-shaped annular groove 7 corresponding with rubber bail 8 on the mesa sidewall, under described dust cap 4 End be embedded into the annular groove 11 on the lateral surface of inner ring 2, described retainer 5 include be arranged symmetrically ball 3 is clamped it is spacing Ring 6, the upper and lower ends of described spacing ring 6, which cross out, is disposed with location division 10, and being disposed with tip on the location division 10 dashes forward Play bar 9, the tip protuberant bar 9 is embedded into V-ring groove 12 corresponding on the madial wall of outer ring 1, described tip protuberant bar 9 with Gap is left between V-ring groove 12 and is filled with lubricant grease, the coefficient of curvature of described inner ring 2 is 0.535.

Spacing ring 6 has certain toughness, tip protuberant bar 9 is embedded into V-ring groove 12 when installation, protects Card retainer 5 will not move axially, but can ensure that retainer 5 can be with ball 3 by being filled with lubricant grease in gap High-speed mobile together.

Preferably, the madial wall of described spacing ring 6 is arcwall face, the shape of the arcwall face and ball 3 match and with An intersegmental gap is left between ball 3.

The utility model uses special retainer structure, can guarantee that the high intensity steady operation of ball, and using card Fixed dust cap is connect, good sealing effect, prevents grease leakage, adds the inclination angle of bearing, when preventing bearing high-speed motion It is stuck.
