Abstract

The utility model relates to a thread-type insert bearing which comprises a bearing outer ring, a bearing inner ring and a roller body arranged between the bearing outer ring and the bearing inner ring, seal rings are arranged on both sides of the roller body, dustproof covers are arranged on the lateral sides of the seal rings, the inner hole of the bearing inner ring is thread-shaped. The thread-type insert bearing has the advantages that the thread-type insert bearing has good dustproof effect and can work in heavy soil or dust environment, and has simple structure, convenient mounting and use, and low cost.

Description

The thread type bearing with spherical outside surface

Technical field

The utility model relates to a kind of bearing, relates in particular to a kind of thread type bearing with spherical outside surface.

Background technique

Present bearing is commonly used, and to add the method for seal ring dustproof, but structure is too simple, especially can not prevent effectively that the bearing that dust causes from grinding problem in the bigger bad border of earth or dust.

The model utility content

The technical problems to be solved in the utility model is: a kind of thread type bearing with spherical outside surface is provided, makes it can be effectively dustproof, and easy to install, cost is low.

In order to overcome the defective that exists in the background technique, the technological scheme that its technical problem that solves the utility model adopts is: a kind of thread type bearing with spherical outside surface, comprise bearing outer ring, bearing inner race and be arranged on bearing outer ring and bearing inner race between rolling element, the both sides of rolling element be provided with seal ring, it is characterized in that: the arranged outside of described seal ring has dust cover, and the endoporus of described bearing inner race is shape of threads.

Described dust cover comprises skeleton and the rubber lip that is adhered to the skeleton inboard, and described skeleton is connected on the outer surface of bearing outer ring, and rubber lip contacts with the bearing inner race outer surface.

The utility model has solved the defective that exists in the background technique, and good dustproof effect can be worked in the bigger environment of earth or dust, and simple in structure, easy to install, cost is low.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model thread type bearing with spherical outside surface.

Among the figure: the 1-bearing outer ring; The 2-bearing inner race; The 3-rolling element; The 4-seal ring; The 5-dust cover; The 5-1-skeleton; The 5-2-rubber lip.

Embodiment

Thread type bearing with spherical outside surface as shown in Figure 1, comprise bearing outer ring 1, bearing inner race 2 and be arranged on bearing outer ring 1 and bearing inner race 2 between rolling element 3, the both sides of rolling element 3 be provided with seal ring 4, the arranged outside of described seal ring 4 has dust cover 5, dust cover 5 comprises skeleton 5-1 and is adhered to the rubber lip 5-2 of skeleton inboard, described skeleton 5-1 is connected on the outer surface of bearing outer ring 1, and rubber lip 5-2 contacts with bearing inner race 2 outer surfaces, and the endoporus of described bearing inner race 2 is shape of threads.The setting of dust cover 5 makes bearing except original seal ring sealing function, increase sealing together again, can prevent effectively that magazines such as extraneous dust, water smoke, fluid from sticking on the seal ring 4, infiltrated the bearing the inside, thereby the usability that keeps bearing, the working life of prolongation bearing.The utility model thread type bearing with spherical outside surface is mainly used in the suspension transmission of production lines such as food machinery, spray coating mechanical, harbour machinery.
