Description

Mute type needle roller bearing

Technical Field

The utility model relates to a hush air type bearing belongs to bearing technical field.

Background

The needle bearing is a roller bearing with cylindrical rollers, the rollers are thin and long relative to the diameter of the roller bearing, the rollers are called needle rollers, the bearing has high load bearing capacity despite of small section, the needle bearing is provided with the thin and long rollers, therefore, the radial structure is compact, the inner diameter size and the load bearing capacity are the same as those of other types of bearings, the outer diameter is the smallest, and the needle bearing is particularly suitable for the supporting result with limited radial installation size, the needle bearing is a common component in the mechanical transmission process, but the existing needle bearing is easily influenced by foreign matters such as dust, scrap iron and the like during the working process, the use of the bearing is influenced, and noise is generated when the bearing is used.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model overcomes current defect, provides a mute type bearing to solve the problem in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a mute needle roller bearing, includes the outer lane, the outer lane inboard is equipped with the inner circle, be equipped with the holder between inner circle and the outer lane, be equipped with a plurality of logical grooves that evenly set up on the holder, it is equipped with the kingpin to lead to the inslot, just the kingpin both ends are rotated and are connected the holder, the both sides of holder are connected with the annular slab, just the annular slab is located between outer lane and the inner circle, the relative one side of annular slab is equipped with the amortization cotton, the one side that the amortization cotton was kept away from mutually is equipped with the bloop, just the bloop evenly is located on the annular slab.

Furthermore, the central axes of the inner ring, the outer ring and the retainer are positioned on the same straight line.

Further, the diameter of the needle roller is larger than the thickness of the retainer.

Furthermore, the outer side of the needle roller is abutted against the inner ring and the outer ring.

Further, the distance between the outer ring and the inner ring is consistent with the diameter of the needle roller.

Furthermore, the two ends of the retainer penetrate through the silencing cotton to be fixedly connected with the annular plate.

The utility model has the advantages that: the utility model discloses in the annular plate that sets up can avoid in external dust, fine sand, impurity such as iron fillings get into the bearing to friction impurity produces the noise when avoiding the bearing to use, the inboard amortization cotton of annular plate and bloop can noise absorption, reduce the noise that bearing self produced, be favorable to bearing's use.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

As shown in fig. 1-3, a mute needle roller bearing comprises an outer ring 1, an inner ring 2 is arranged on the inner side of the outer ring 1, a retainer 3 is arranged between the inner ring 2 and the outer ring 1, a plurality of through grooves 4 are uniformly arranged on the retainer 3, needle rollers 5 are arranged in the through grooves 4, two ends of the needle rollers 5 are rotatably connected with the retainer 3, two sides of the retainer 3 are connected with annular plates 6, the annular plates 6 are arranged between the outer ring 1 and the inner ring 2, silencing cotton 7 is arranged on one side, opposite to the annular plates 6, silencing holes 8 are formed in one side, away from the silencing cotton 7, of the annular plates 6, and the silencing holes 8 are uniformly formed in the annular plates 6.

Specifically, as shown in fig. 1, the central axes of the inner ring 2, the outer ring 1, and the retainer 3 are on the same straight line.

Specifically, as shown in fig. 2, the diameter of the needle roller 5 is larger than the thickness of the cage 3, the outer side of the needle roller 5 abuts against the inner ring 2 and the outer ring 1, the distance between the outer ring 1 and the inner ring 2 is the same as the diameter of the needle roller 5, and the two ends of the cage 3 penetrate through the silencing cotton 7 to be fixedly connected with the annular plate 6.
