Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Specific example 1: referring to fig. 1, in an embodiment of the present invention, a fastening type bearing mounting structure includes a bearing 1, a sleeve 2, a nut 3, and a gasket 4, where the inside of the sleeve 2 is used to connect a rotating shaft, the bearing 1 is sleeved outside the sleeve 2 and fixedly connected to the sleeve 2, the nut 3 is provided with an internal thread 32, one end of the sleeve 2 of the bearing 1 is provided with an external thread 21 matched with the internal thread 32, the sleeve 2 and the nut 3 are screwed with each other through the internal thread 32 and the external thread 21, the gasket 4 is sleeved on the sleeve 2 and the gasket 4 is located between the nut 3 and the bearing 1, the gasket 4 is clamped to the sleeve 2, the sleeve 2 is provided with an opening 5, and the opening 5 penetrates through two ends of the sleeve 2.

Referring to fig. 2 to 4, the gasket 4 includes a washer 41 and internal teeth 42 disposed on the washer 41, the internal teeth 42 are disposed toward an axial direction of the washer 41, and the internal teeth 42 are engaged with the sleeve 2. The outside of nut 3 evenly is equipped with a plurality of first draw-in grooves 31, the packing ring 41 outside evenly is equipped with a plurality of and first draw-in groove 31 assorted external tooth 43, external tooth 43 is through first draw-in groove 31 and nut 3 looks joint.
