Description

Special bearing structure for lifting ultra-micro camera

Technical Field

The utility model belongs to the technical field of the bearing, a special bearing structure of special miniature camera lift is related to.

Background

The camera generally has the basic functions of video shooting, transmission, static image capture and the like, and processes and converts an image into a digital signal which can be identified by a computer by a photosensitive component circuit and a control component in the camera after the image is collected by a lens, and then the digital signal is input into the computer by a parallel port or a USB connection and then is restored by software.

The camera rotation angle is shot and needs to be provided with a rotating device, and the core component of the rotating device belongs to the bearing. The sensitivity of the rotation device to the elevation and rotation is ensured by the precision of the bearing. Along with the increasingly fierce market competition, the camera is required to rotate flexibly, shoot at three hundred sixty degrees without dead angles, and the rotation is light and handy, and has no clamping stagnation, no noise and the like, and the degree is more and more strict.

The bearing for lifting the camera mainly comprises a bearing outer ring, a bearing inner ring and a bearing rolling body. The bearing inner ring is assembled by adopting a two-inner-ring separated structure, and lubricating oil is arranged in the bearing, so that the bearing is light and smooth in use and rotation process.

Disclosure of Invention

The utility model provides an above-mentioned problem, provide a special bearing structure of special miniature camera lift, this bearing structure simple to operate is swift, can bear great load.

According to the technical scheme of the utility model: the utility model provides a special bearing structure of super miniature camera lift which characterized in that: the structure comprises a bearing inner ring right structure and a bearing inner ring left structure which is connected with the bearing inner ring right structure in a matching mode, a shaft sleeve portion and a right limiting conical surface are formed on the bearing inner ring right structure, the bearing inner ring left structure is sleeved on the shaft sleeve portion, a left limiting conical surface is formed on the bearing inner ring left structure, and a V-shaped groove is formed between the left limiting conical surface and the right limiting conical surface.

As a further improvement, the right end face of the left structure of the bearing inner ring is abutted against the step face of the right structure of the bearing inner ring.

As a further improvement, the left end of the structure on the left side of the bearing inner ring is provided with a counter bore, and the right end of the structure on the right side of the bearing inner ring is provided with a taper hole.

As a further improvement of the utility model, the outer diameters of the left structure of the bearing inner ring and the right structure of the bearing inner ring are the same and are both 2.0-2.2 mm; the inner diameter of the left structure of the bearing inner ring is 1.25-1.27mm, and the inner diameter of the right structure of the bearing inner ring is 1.000-1.010 mm.

As a further improvement of the utility model, the left side structure of the bearing inner ring is equal to the axial length of the shaft sleeve part and is 0.49-0.51 mm.

The technical effects of the utility model reside in that: the utility model discloses the product changes the integrative device of original bearing inner race into bearing inner race left and right sides two parts device, and inside this structure guaranteed that the steel ball packs into the bearing smoothly, and can bear the load requirement of requirement. The original structure bearing rolling element is inconvenient to be arranged in the bearing, the number of the bearing rolling elements is small, the bearing requirement cannot be met, the modified bearing inner ring is of a structure with two parts, and the bottleneck problem that the original structure is inconvenient to arrange balls is solved. Meanwhile, the requirement of actual working conditions can be met due to the large ball loading quantity. The structure of the ultra-micro camera lifting system is greatly optimized, and the bearing requirement is met while the smooth operation of the lifting system is ensured.
