Description

Mute roller

Technical Field

The utility model relates to a silence gyro wheel is refered in particular to in gyro wheel technical field.

Background

In the middle of the actual life, various wheels are used in multiple occasions, for example, in some furniture industries, various drawers, doors and windows and the like need to slide relatively, a large number of rail wheels can be used, the use of the wheels can reduce the push-pull force in the process of pulling the drawer or sliding the door and window, the life of people is greatly facilitated, and the various rail wheels on the market at present have the following common structures: the all-plastic, all-metal or metal wheel or plastic wheel using bearings inside is adopted, in the rail wheels with the structures, the all-metal rail wheels such as steel wheels, iron wheels and the like have better wear resistance, but have the defects of difficult production and processing and high cost, although the plastic wheels have smaller weight and are convenient for mass production, because the strength of the plastic is smaller, the wear resistance is poorer compared with that of the metal, and the plastic is aged when being used for a long time in places with large temperature change or direct sunlight, cracks or pits are easily generated on the surface of the wheel, so that the performance of the wheel is reduced or scrapped.

The existing Chinese patent: a metal rolling surface composite wheel, bulletin number: CN203762640U, announcement date: 2014.8.13, at least the ring stress surface of the rolling ring which directly contacts with the rail and rolls adopts sheet metal, the wheel core in the rolling ring adopts non-metal material with certain intensity, the whole rolling ring adopts metal material, but this structure does not mention the installation of the inner ring and the outer ring, in the actual installation process, the ball is arranged between the inner ring and the rotating shaft, the inner ring is directly plugged into the outer ring, the outer ring and the inner ring both adopt metal material, and the metal material has certain error because of the processing, in order to make the inner ring installed in the outer ring, therefore the inner ring has certain gap when matching with the outer ring, which causes the roller wheel to have certain bounce when in use, the shock resistance is poor, the stress between the inner ring and the outer ring is uneven, the service life is affected, and the outer ring adopts metal material, and the rail is also metal material, the noise is easily generated, the abrasion is serious, the buffering performance is poor, and the vibration is easily generated.

SUMMERY OF THE UTILITY MODEL

To above problem, the utility model provides a silence gyro wheel is equipped with the rubber ring between inner ring and the outer loop, has cushioned the impact force between inner ring and the outer loop, also makes between inner ring and the outer loop fixed more firm, has also reduced the machining precision requirement of inner ring and outer loop, also makes the inner ring atress even, prolongs its life, and the outer loop outside is equipped with sealed glue moreover, and the gyro wheel during operation has certain buffer function like this, reduces the noise of its production.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

the utility model provides a silence gyro wheel, is equipped with ball, its characterized in that including axle core, inner ring and outer loop between axle core and the inner ring: a rubber ring is arranged between the inner ring and the outer ring, the cross section of the outer ring is U-shaped, and a sealant is arranged on the outer side of the outer ring.

Preferably, the sealing gum is not arranged on the exposed bottom of the U-shaped bottom of the outer ring, and because the bottom is a stressed part and is easily worn away during rolling, the sealing gum with poor wear resistance is not needed.

Preferably, the width of the rubber ring is the same as that of the inner ring, so that the inner ring is uniformly stressed.

Preferably, the ball both sides still are equipped with the sealing ring, circle both sides are equipped with the recess respectively in the inner ring, the sealing ring with the recess corresponds the cooperation, can keep off the ball like this, avoids into the dust to ensure the life of silence gyro wheel.

The utility model discloses beneficial effect:

the utility model discloses a be equipped with the rubber ring between inner ring and the outer loop, cushioned the impact force between inner ring and the outer loop, also make between inner ring and the outer loop fixed more firm, also reduced the machining precision requirement of inner ring and outer loop, also make the inner ring atress even, prolong its life, the outer loop outside is equipped with sealed glue moreover, the gyro wheel during operation has certain buffer function like this, reduces the noise of its production.

Drawings

Fig. 1 is a front view of the present invention;

fig. 2 is a sectional view taken along the plane a-a of fig. 1.

Detailed Description

The technical solution of the present invention will be described below with reference to the accompanying drawings and examples.

As shown in fig. 1 to 2, a silence gyro wheel, including axle core 1, inner ring 2 and outer loop 3, axle core 1 is at the most inboard, is equipped with ball 4 between axle core 1 and the inner ring 2, and outer loop 3 is located outside inner ring 2, and outer loop 3 and inner ring 2 reciprocal anchorage, be equipped with a rubber ring 5 between inner ring 2 and the outer loop 3, the outer loop 3 cross-section is "U" type, is used for cooperating with the track, the outer loop 3 outside is equipped with sealed glue 6, the "U" type bottom of outer loop 3 exposes and does not establish sealed glue 6, because this department is the atress part, wears out easily during the roll, consequently just need not adopt the relatively poor sealed glue 6 of wearability, but directly lets metal material's outer loop 3 expose outside.

Specifically, the width of rubber ring 5 with the width of inner ring 2 is the same, and the atress is even on inner ring 2 like this, avoids 2 local atress deformations of inner ring like this, has improved inner ring 2's life, and sealed glue 6 wraps up rubber ring 5, can avoid rubber ring 5 to drop like this.

Specifically, 4 both sides of ball still are equipped with sealing ring 7, circle both sides are equipped with the recess respectively in inner ring 2, sealing ring 7 with the recess corresponds the cooperation, can block ball 4 like this, avoids advancing the dust in the ball 4 to ensure the life of silence gyro wheel.

The utility model discloses a be equipped with rubber ring 5 between inner ring 2 and the outer loop 3, cushioned the impact force between inner ring 2 and the outer loop 3, also make between inner ring 2 and the outer loop 3 fixed more firm, reduced the machining precision requirement of inner ring 2 and outer loop 3, also make 2 atress of inner ring even, prolong its life, the 3 outsides of outer loop are equipped with sealed glue 6 moreover, the gyro wheel during operation has certain buffer function like this, reduces the noise of its production.
