Abstract
The utility model belongs to the technical field of bearing and relates to a novel rotary principal shaft for a medical spiral CT machine, which comprises an outer ring, a retainer, an inner ring, seal rings and rolling bodies. The bearing is not provided with ball holes; the outer track of the inner ring is put against the inner track of the outer ring; the rolling bodies are put into a raceway from the maximum radial gap between the inner ring and the outer ring and then the rolling bodies are evenly distributed on the raceway; then the retainer is inserted into the room between the inner ring and the outer ring from the top of the bearing; and finally the seal rings are respectively installed in the seal grooves of the inner ring and the outer ring. The rotary principal bearing has the advantages that the bearing is dispensed with the conventional ball holes, thus reducing the noise of the bearing; the radius of the curvature of the raceway is arranged to be equal to the diameter of the rolling bodies, which is different from the common holding capacity coefficient of 0.53, thus reducing the friction of the bearing; and a quenching soft belt is omitted, thus avoiding the vibration produced when the rolling bodies pass through the quenching soft belt.
Description
Technical field
The utility model belongs to technical field of bearings, relates 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 utility model provides a kind of 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 utility model is: a kind of 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 beneficial effects of the utility model are, have cancelled traditional dress ball hole, have 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
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, outer ring, 2, retainer, 3, inner ring, 4, seal ring, 5, rolling element.
Embodiment
As shown in Figure 1, the utility model 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.
