Abstract

The invention discloses a micro high-speed inner-ring-free ball bearing. The micro high-speed inner-ring-free ball bearing comprises a bearing outer ring and balls. A folded edge is inwards arranged on one side of the bearing outer ring, and a ring groove is formed in the upper half portion of the bearing outer ring. The micro high-speed inner-ring-free ball bearing further comprises a ball frame. The ball frame is arranged in the ring groove of the bearing outer ring. The ball frame is formed by bending a metal sheet, and multiple ball holes are formed in the metal sheet. One side of each ball hole is pressed to form a limiting face, wherein the limiting face is located on the inner side of the ball frame, and the hole diameter of the limiting face is smaller than the diameter of the balls. The micro high-speed inner-ring-free ball bearing is convenient to produce and low in cost, the structure is simple so that the bearing can adapt to automatic production, operation is simple and fast, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a miniature high-speed ball bearing without an inner ring. Background technique [0002] At present, the production cost of miniature bearings of air turbine handpieces is high, and the assembly is inconvenient, which is an important threshold in the development of disposable air turbine handpieces. Contents of the invention [0003] In order to overcome the shortcomings of high production cost and inconvenient assembly of the miniature bearings of the existing pneumatic turbine handpiece, the invention provides a miniature high-speed ball bearing without an inner ring. [0004] The technical solution of the present invention to solve the technical problem is: a miniature high-speed ball bearing without an inner ring, including a bearing outer ring and balls, one side of the bearing outer ring is provided with a flanging inward, and the upper half of the bearing outer ring is provided with a The ring groove also includes a b...
