Description

Technical Field

[0001] The utility model relates to the field of electronic product accessories, in particular to an installation structure of an electric hammer rotor and a bearing chamber of a housing. Background Art

[0002] At present, most motor tools will use an important component, the rotating shaft. The patent publication document CN220470589U discloses an installation structure of a rotating shaft. In this structure, double bearings are arranged in the housing to support the rotating shaft. Using double bearings to support the rotating shaft can improve the stability of the rotating shaft during rotation. However, in this structure, there is no buffer structure between the bearing (reference numeral 4 in the document) and the housing (reference numeral 1 in the document), and there is a gap between the two bearings themselves. Therefore, in this structure, the bearing itself is prone to vibration and movement. So, although this structure is provided with double bearings, this structure cannot make the rotating shaft rotate stably. Summary of the Utility Model

[0003] Aiming at the above problems, the utility model provides an installation structure of an electric hammer rotor and a bearing chamber of a housing. By arranging an X-shaped sealing ring between the bearing and the bearing seat, the installation stability of the bearing itself is increased by using the X-shaped sealing ring, ensuring that the rotating shaft can maintain stability during rotation.

[0004] The technical solution adopted by the utility model is as follows:

[0005] An installation structure of an electric hammer rotor and a bearing chamber of a housing, including a housing and a rotating shaft. The rotating shaft is arranged in the housing, and further includes a bearing seat, a bearing and an X-shaped sealing ring. The bearing seat is arranged on the housing, the bearing is arranged in the bearing seat, the X-shaped sealing ring is arranged in the bearing seat, the X-shaped sealing ring is located between the bearing and the bearing seat, the outer wall of the X-shaped sealing ring is in close contact with the bearing seat, the inner wall of the X-shaped sealing ring is in close contact with the bearing, the X-shaped sealing ring is an X-shaped sealing ring made of soft rubber material, and the rotating shaft is in rotational cooperation with the bearing.

[0006] In this structure, an X-shaped sealing ring made of soft rubber material is arranged between the bearing and the bearing seat. The X-shaped sealing ring can not only play a role in shock absorption and buffering between the bearing seat and the bearing, but also increase the frictional resistance between the bearing and the bearing seat, ensuring that the bearing is not prone to relative movement relative to the bearing seat. Therefore, in this structure, the installation stability of the bearing is greatly improved by arranging the X-shaped sealing ring, ensuring that the rotating shaft can rotate stably.

[0007] In summary, in this structure, by arranging an X-shaped sealing ring between the bearing and the bearing seat, the installation stability of the bearing itself is increased by using the X-shaped sealing ring, ensuring that the rotating shaft can maintain stability during rotation.

[0008] Optionally, there are two bearings, the two bearings are in a parallel state, and an X-shaped sealing ring is arranged between each bearing and the bearing seat.

[0009] The force-bearing area of the double bearings is larger than that of a single bearing, and the force borne by each bearing is smaller, which is more conducive to the rotation shaft to maintain stability during operation.

[0010] An X-shaped sealing ring is arranged between each bearing and the bearing seat, which can ensure that each bearing is in a stable installation state.

[0011] Optionally, the X-shaped sealing rings are in a parallel state.

[0012] Optionally, the bearing seat is provided with a circular groove, and the X-shaped sealing ring is arranged in the circular groove.

[0013] A circular groove is opened on the bearing seat, and the X-shaped sealing ring is arranged in the circular groove, so that the clamping installation of the X-shaped sealing ring is realized, and it is ensured that the X-shaped sealing ring can be stably clamped in the bearing seat.

[0014] Optionally, the bearing seat is an aluminum bearing seat.

[0015] Specifically, the bearing seat is an aluminum bearing seat, the housing is a plastic housing, and the bearing seat and the housing are integrally formed.

[0016] Optionally, it further includes a first dust-proof ring, the first dust-proof ring is arranged on the rotating shaft, and the first dust-proof ring is located inside the housing.

[0017] Specifically, the first dust-proof ring is a centrifugal first dust-proof ring, and the function of the first dust-proof ring is to blow the foreign matters and dust attracted by the magnetic steel sheet to the surrounding. Specifically, the first dust-proof ring is a plastic dust-proof ring.

[0018] Optionally, it further includes a second dust-proof ring, the second dust-proof ring is arranged on the rotating shaft, the second dust-proof ring is located outside the housing, and the bearing is located between the first dust-proof ring and the second dust-proof ring.

[0019] Specifically, the second dust-proof ring is designed in the shape of an impeller, and the second dust-proof ring is installed on the rotating shaft and rotates together with the rotating shaft. In this way, it can not only reduce the temperature of the brushless controller at the handle and improve the service life of the machine, but also prevent dust from entering, with simple assembly, convenient disassembly and convenient bearing replacement.

[0020] Optionally, the bearing seat is clamped in the housing.

[0021] The beneficial effect of the present utility model is that by arranging an X-shaped sealing ring between the bearing and the bearing seat, the stability of the bearing itself is increased by using the X-shaped sealing ring, and it is ensured that the rotating shaft can maintain stability during rotation.
