Embodiment Construction

[0017] In conjunction with the accompanying drawings, the following embodiments of the present invention are given, but the present invention is not limited to the following embodiments.

[0018] The CT machine spindle bearing described in this embodiment is a double-row angular contact ball slewing bearing, which is a radial bearing, made of surface hardened steel, and mainly bears the combined load of radial force and overturning moment. It includes an outer ring 1, an inner ring 4, a second inner ring 8, a second outer ring, steel balls 3, and a cage 7. The inner ring and the second inner ring form a combined inner ring, and the outer ring is toothed or not. There are two structures with teeth, the steel ball and the cage are installed between the combined inner ring and the outer ring; or the outer ring and the second outer ring form a combined outer ring, and the inner ring is toothed or not structure, the steel balls and the cage are installed between the combined outer ...

Abstract

The invention discloses a spindle bearing of a CT (Computed Tomography) machine, which comprises an outer ring (1), an inner ring (4), a second inner ring (8), a steel ball (3) and a retainer (7). A structure that a combined inner ring and the outer ring are provided with teeth or are not provided with the teeth is formed by the inner ring and the second inner ring, and the steel ball and the retainer are arranged between the combined inner ring and the outer ring; or a structure that a combined outer ring and the inner ring are provided with teeth or are not provided with the teeth is formed, and the steel ball and the retainer are arranged between the combined outer ring and the inner ring. The problems of high processing difficulty, complex structure and high production cost of the existing wire raceway bearing and thin-wall uniform-section bearing are solved. Under the condition with the same appearance size, an embedded structure is changed into an integrated structure, so that the aims of simplifying a machining process, reducing the production cost, prolonging the service life and improving the reliability are fulfilled.

Description

technical field [0001] The invention belongs to a double-row angular contact ball turntable bearing, and mainly relates to a CT machine main shaft bearing. Widely used in various medical or industrial uses. Background technique [0002] Four-point contact ball slewing bearings are widely used in low-speed CT machines due to their mature and reliable technology and low cost. However, it cannot meet the high speed, low noise, high precision, low vibration, and long life requirements of high-speed CT machines. The main reasons are: 1. The bearing load of high-speed CT machines is greater, especially The overturning moment is large. 2. Under the action of the overturning moment, the steel ball and cage assembly of the four-point contact ball slewing bearing will enter and exit the load area with the opposite force direction twice during the one-rotation movement process, which will greatly disturb the cage. At present, the high-speed models used in medical or industrial CT ma...
