[0003] With the continuous progress of technology in the small household appliance field, many mechanisms requiring linear motion are realized by rotary motion and connecting rod mechanism, however, this conversion mode inevitably has loss when energy is converted from one form to another, and due to the friction between mechanical parts and imperfect matching, a large noise is generated in the operation process.

[0004] Therefore, the utility model provides a sliding sleeve bearing for bearing radial load and can linear motion. UTILITY MODEL CONTENT

[0005] The utility model aims at solving the shortcomings in the prior art, and provides a sliding sleeve bearing for bearing radial load and can linear motion.

[0006] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme: a sliding sleeve bearing for bearing radial load and can linear motion, comprising bearing assembly and rotating shaft;

[0007] The bearing assembly comprises oil seal cover, the oil seal cover is provided with two, the outer side of the oil seal cover is fixedly connected with outer steel sleeve, the inside of the outer steel sleeve is provided with inner sliding sleeve, the inside of the inner sliding sleeve is provided with inner steel sleeve, and the inside of the inner sliding sleeve is provided with steel ball.

[0008] As a preferred embodiment, the inner steel sleeve is movably connected to the rotating shaft.

[0009] The technical effect of the above technical scheme is that the energy loss in mechanical motion can be effectively reduced, so that the bearing can realize smoother linear motion when bearing radial load.

[0010] As a preferred embodiment, the outer side of the steel ball is movably connected to the inside of the outer steel sleeve.

[0011] The technical effect of the above technical scheme is that the steel ball can freely roll or slide according to the change of external force, thereby reducing friction and wear.

[0012] As a preferred embodiment, the outer side of the steel ball is movably connected to the outside of the inner steel sleeve.

[0013] The technical effects of the above technical scheme are that the steel ball can freely roll or rotate without leaving its track, so that the entire device operates more smoothly.

[0014] As a preferred embodiment, the inner sliding sleeve is made of copper.

[0015] The technical effects of the above technical scheme are that the inner sliding sleeve can withstand greater pressure and friction during use and is not prone to deformation or damage.

[0016] As a preferred embodiment, the outer steel sleeve, the inner steel sleeve and the steel ball are made of bearing steel.

[0017] The technical effects of the above technical scheme are that the bearing capacity and impact resistance of the bearing are improved, so that the bearing can maintain a good working state under various complex working conditions.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are that,

[0019] The inner steel sleeve in the bearing assembly is movably connected to the rotating shaft, and the steel balls are uniformly distributed between the inner steel sleeve and the outer steel sleeve. When the rotating shaft rotates, the steel balls roll between the inner and outer steel sleeves, thereby converting the original sliding friction into rolling friction. This design reduces the friction coefficient of rolling friction compared to sliding friction, reduces the friction, and reduces the energy loss and the wear of the bearing, thereby improving the working efficiency and service life of the bearing. In addition, the noise generated by rolling friction is smaller than that generated by sliding friction, which improves the comfort of the user. This can effectively reduce the energy loss in the conversion process, and due to the reduction of friction and noise between mechanical parts, it is suitable for applications that require frequent movement and greater pressure.
