Abstract

The invention belongs to the technical field of miniature bearings, particularly relates to a stainless steel miniature bearing. To solve the problem that balls are seriously damaged due to poor sealing and lubricating effects in miniature bearings in the prior art, the invention discloses the following scheme: the stainless steel miniature bearing comprises a bearing outer ring and a bearing inner ring which are coaxially distributed and mutually sleeved together, wherein a rib is reserved on the outer wall of the circumference of the bearing inner ring close to the middle part, inner rolling grooves are formed in two sides of the rib, combined rollers which are distributed at equal intervals are connected in rolling grooves of the inner rolling grooves in a rolling manner, the axial leads of the combined rollers on two sides of the rib are distributed in an inverted-V-shaped mode, and outer rolling grooves which are parallel to the inner rolling grooves are formed in the inner wall of the circumference of the bearing outer ring. The sealing effect between the inner ring and the outer ring of the bearing is improved, internal lubricating grease can be prevented from overflowing, the contact material of the inner ring and the outer ring is a rubber material, the contact surface is convenient to slide under the action of the grease and has very small resistance, and external water is difficult to squeeze in due to the arrangement of a contact inclined surface of the outer wall of the rubber sealing ring.

Description

technical field [0001] The invention relates to the technical field of miniature bearings, in particular to a stainless steel miniature bearing. Background technique [0002] Precision bearings for machine tools and other high-precision applications require superior performance, including a wide range of speed capabilities, maintaining high rotational accuracy, high system rigidity, low heat generation, low noise, and low vibration levels. The structural basis for maintaining these properties of precision bearings lies in high-precision components and robust assembly processes. The miniature bearings used in mobile phones, watches, and instruments belong to this type of precision bearings, but compared with traditional precision bearings, miniature bearings have very obvious volume characteristics, that is, their volume is abnormally small. [0003] The structure of the miniature bearing in the prior art includes an outer ring, an inner ring and steel balls. During manufact...
