Abstract
The utility model discloses a steering gear shell rotary shaft hole waterproof structure, which includes a shell, shaft holes which are located on the shells and a rotating shaft which are inserted in the shaft hole. The shaft holes are also provided with the sleeved on a rotating shaft rubber ring and a bearing. The inner rotor of the bearing is linked with the spindle, and the outer rotor is linked with the shell. The rotation shaft and the rubber ring are isolated by the layer of water-and-oil-proof in order to reduce friction between the rotation shaft and the rubber ring effectively. At the same time, the installation of the bearing can make the rotation shaft have a good performance.
Description
Technical field
The utility model relates to field of mechanical technique, is specifically related to a kind of waterproof construction of steering wheel shell rotation axis hole.
Background technology
Steering wheel is made of shell, circuit board, coreless motor, gear and position detector, shell and rotating shaft junction need to guarantee that rotating shaft can rotate flexibly, also will guarantee the water-stop at this place simultaneously, to prevent that water from entering enclosure, damage inner electronic component.
Steering wheel rotation axis hole place adopts circular cushion rubber to come waterproof on the market at present, and the shortcoming of this kind structure is easy to wear, and the machine of need often tearing open is changed cushion rubber, and cushion rubber and rotating shaft friction, makes that the rotating shaft rotational resistance is big, and waterproof effect is relatively poor simultaneously.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of waterproof construction of steering wheel shell rotation axis hole, and it can not influence the rotation of rotating shaft, good water-proof effect.
For achieving the above object, the utility model adopts following technical scheme:
The waterproof construction of steering wheel shell rotation axis hole, comprise shell, be arranged at axis hole and the rotating shaft of cross-under in axis hole on the shell, the glue ring and the bearing that are socketed in the described rotating shaft also are installed in the described axis hole, and the internal rotor of described bearing is connected with rotating shaft, and external rotor is connected with described shell.
Described glue ring is positioned at the top of described bearing, all is folded with watertight composition between itself and shell and the rotating shaft.
The madial wall of described shell, the periphery that is positioned at axis hole is provided with one recess is installed, and described bearing is positioned at described installation recess.
The S-shaped section of described glue ring.
The waterproof construction of the steering wheel shell rotation axis hole that the utility model is set forth, its beneficial effect is:
By the waterproof zonal isolation, can effectively reduce the friction of rotating shaft and glue ring between rotating shaft and the glue ring; Simultaneously, by Bearing Installation, make rotating shaft have good rotating property.
Description of drawings
Fig. 1 is the schematic diagram of the waterproof construction of a kind of steering wheel shell rotation of the utility model axis hole.
Embodiment
Below, in conjunction with the accompanying drawings and embodiment, the waterproof construction of steering wheel shell rotation axis hole of the present utility model is described further so that clearerly understand the utility model technological thought required for protection.
As shown in Figure 1, the waterproof construction for a kind of steering wheel shell rotation axis hole of the present utility model comprises shell 1, rotating shaft 2, has an axis hole 11 on the shell 1, and rotating shaft 2 is inserted in the axis hole 11; At the inwall of shell 1, be positioned at the medial extremity periphery of axis hole 11, offer one recess 12 is installed, install in the recess 12 bearing 4 is housed, its internal rotor is connected with rotating shaft 2, and external rotor is connected with shell 1, rotating shaft 2 can be rotated with respect to shell 1 by bearing 4, has rotating property preferably.
In axis hole 11, be positioned at the top of bearing 4, suit one special-shaped glue ring 3 in rotating shaft 2, scribble waterproof oil reservoir 6 between abnormity glue ring 3 and the rotating shaft 2, simultaneously, scribble waterproof oil reservoir 5 between special-shaped glue ring 3 and the shell 1, thereby effectively prevent to enter shell 1 inside from the water that axis hole 11 flows into.
The coating of waterproof oil reservoir 5 and waterproof oil reservoir 6 for convenience, the S-shaped section of cushion rubber 3.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to technical scheme described above and design.
Claims (4)
1. the steering wheel shell rotates the waterproof construction of axis hole, comprise shell, be arranged at axis hole and the rotating shaft of cross-under in axis hole on the shell, it is characterized in that, the glue ring and the bearing that are socketed in the described rotating shaft also are installed in the described axis hole, the internal rotor of described bearing is connected with rotating shaft, and external rotor is connected with described shell.
2. the waterproof construction of steering wheel shell as claimed in claim 1 rotation axis hole is characterized in that described glue ring is positioned at the top of described bearing, all is folded with watertight composition between itself and shell and the rotating shaft.
