Abstract
The utility model discloses a be used for hinge silence pressure bearing, through the even embedded steel ball of integrated into one piece's plastics holder, the outside surrounds the steel ball by upper and lower concave piece seals, supports the novel design of steel ball motion jointly, greatly reduced the noise that the long-time use of hinge produced, effectively improved the life of bearing, simple installation simultaneously, reduction in production cost.
Description
Technical Field
The utility model relates to a bearing, more specifically the silence pressure bearing who uses at hinge that says so relates to one kind.
Background
The bearing is used as an important part in the door hinge, and has the function of bearing the upper door hinge rotating body and the lower door hinge rotating body to ensure smooth rotation. Most bearings matched with the existing door hinge generate contact friction with the inner diameter surface of the bearing when a door hinge rotating shaft works, so that great noise is generated after long-term use, and the service life is shortened. Therefore, a silent bearing is needed to solve the noise problem and improve the use efficiency.
Disclosure of Invention
The utility model aims at solving the problem that the supporting bearing of current hinge is not enough and the silence pressure bearing that provides is simple structure not only, and the noise is less, and life is longer, and the uniformity is good moreover.
The utility model discloses an adopt following technical solution to realize above-mentioned purpose: the utility model provides a be used for door hinge silence pressure bearing, includes concave piece, plastics holder and steel ball down, its characterized in that: the plastic retainer is in a ring shape, a plurality of steel ball holes are formed in the plastic retainer along the direction of the ring, the steel balls are uniformly distributed in the steel ball holes of the plastic retainer, the upper concave sheet and the lower concave sheet are respectively arranged above and below the plastic retainer and are in point contact with the plurality of steel balls in the plastic retainer to jointly support the steel balls to move, and the parts form the main structure of the silent pressure bearing.
The plastic retainer is integrally formed by injection molding, and the noise generated by the contact of the inner diameter surface of the plastic retainer and the rotating shaft of the door hinge is greatly reduced to form a silencing device.
The plastic retainer can ensure that the steel balls are supported more stably, the steel balls cannot deviate, each steel ball is stressed the same, and the service life is effectively prolonged.
The upper concave sheet and the lower concave sheet are annularly arranged, are embedded in the upper part and the lower part of the plastic retainer to form closed enclosure, and support the movement of the steel ball together.
The utility model discloses the beneficial effect who reaches: the above technical scheme is adopted in the utility model, novel design greatly reduced through integrated into one piece plastics holder the noise that the hinge used the production for a long time has effectively improved the life of bearing, and the while is simple and convenient to install, reduction in production cost.
Drawings
FIG. 1: the utility model discloses an inner structure design.
FIG. 2: the utility model discloses an overall appearance design picture.
Description of reference numerals: 1. a concave sheet is arranged; 2. a concave sheet; 3. a plastic cage; 4. and (5) steel balls.
Detailed Description
As shown in figure 1, the utility model comprises a 1, an upper concave sheet; 2. a concave sheet; 3. a plastic cage; 4. and (5) steel balls. The plastic retainer is in a ring shape, a plurality of steel ball holes are formed in the plastic retainer along the direction of the ring, the steel balls are uniformly distributed in the steel ball holes of the plastic retainer, the upper concave sheet and the lower concave sheet are respectively arranged above and below the plastic retainer and are in point contact with the plurality of steel balls in the plastic retainer to jointly support the steel balls to move, and the parts form the main structure of the silent pressure bearing.
The plastic retainer is integrally formed by injection molding, and the noise generated by the contact of the inner diameter surface of the plastic retainer and the rotating shaft of the door hinge is greatly reduced to form the silencing device.
The plastic retainer can enable the steel balls to obtain more stable support, the steel balls cannot deviate, each steel ball is enabled to be stressed the same, and the service life is effectively prolonged.
The upper concave sheet and the lower concave sheet are annularly arranged, are embedded in the upper part and the lower part of the plastic retainer to form closed enclosure, and support the movement of the steel ball together.
The above is only the preferred embodiment of the present invention, and the limitation is not the case, so all the equivalent changes or decorations made by the structure, the characteristics and the principle in the application range of the present invention are included in the application range of the present invention.
