Abstract
The invention belongs to the technical field of bearings, and relates to a novel rotary main bearing for medical spiral CT machines, which consists of an outer ring, a cage, an inner ring, sealing rings and rolling elements, wherein the bearing has no ball loading hole; the outer diameter of the inner ring leans against the inner diameter of the outer ring; the rolling elements are loaded into a raceway from a radial maximal clearance of the inner ring and the outer ring; the rolling elements are uniformly dispersed on the raceway; the cage is inserted between the inner ring and the outer ring from a position above the bearing; and finally the sealing rings are loaded into sealing grooves of the inner ring and the outer ring respectively. The main bearing has the advantages of canceling the prior ball loading hole, reducing bearing noise, designing the curvature radius of the raceway to be the diameter of the rolling elements, differing from the conventional containment coefficient of 0.53, reducing bearing friction, canceling quenching soft belts and preventing the rolling elements from vibrating when the rolling elements pass the quenching soft belts.
Description
Technical field
The invention belongs to technical field of bearings, relate to novel medical spiral CT machine rotating main bearing.
Background technique
Along with the continuous development of Chinese national economy, China's medical apparatus and instruments is just progressively caught up with the advanced level of external like product, and constantly improves and development.Traditional bearing can not satisfy at a high speed, the requirement of low noise spiral CT machine.At the requirement of novel spiral CT machine, invent a kind of novel bearing, overcome the shortcoming of old airframe bearing, adapt to the demand of CT machine.
Summary of the invention
The purpose of this invention is to provide novel medical spiral CT machine rotating main bearing, to satisfy the requirement of high speed, low noise spiral CT machine.
Technical solution of the present invention is: novel medical spiral CT machine rotating main bearing, form by outer ring 1, retainer 2, inner ring 3, seal ring 4 and rolling element 5, this bearing arming ball hole, the external diameter of inner ring 3 is leaned against on the internal diameter of outer ring 1, rolling element 5 raceway of packing into from the radially maximal clearance of inner ring 3 and outer ring 1, then rolling element 5 is dispersed on the raceway, again retainer 2 is inserted between inner ring 3 and the outer ring 1 from the bearing top, at last seal ring 4 is respectively charged in the seal groove of inner ring 3 and outer ring 1.
The invention has the beneficial effects as follows, cancelled traditional dress ball hole, reduced the noise of bearing; The raceway radius of curvature is designed to the diameter of rolling element, is different from conventional 0.53 containing coefficient, reduced the friction of bearing; Cancelled the soft band that quenches, avoided rolling element to produce when quenching soft band and vibrated.
Description of drawings
The present invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, outer ring, 2, retainer, 3, inner ring, 4, seal ring, 5, rolling element.
Embodiment
As shown in Figure 1, the present invention is made up of outer ring 1, retainer 2, inner ring 3, seal ring 4 and rolling element 5, it is characterized in that, this bearing arming ball hole, the external diameter of inner ring 3 is leaned against on the internal diameter of outer ring 1, rolling element 5 raceway of packing into from the radially maximal clearance of inner ring 3 and outer ring 1 is dispersed in rolling element 5 on the raceway then, again retainer 2 is inserted between inner ring 3 and the outer ring 1 from the bearing top, at last seal ring 4 is respectively charged in the seal groove of inner ring 3 and outer ring 1.
