Abstract
The utility model relates to a kind of roller bearing preventing string arc to interfere, comprise inner ring, outer ring and cylinder rolling element, the upper end of outer ring and the lower end of inner ring all have rib, outer ring and the involutory rear Formation cross-section of inner ring are the toroidal cavity of rectangle, a circle cylinder rolling element is provided with in this toroidal cavity, each cylindrical roller axially all in annulus chamber in the radial direction, and the rib that the cylinder of each cylinder rolling element all contacts with outer ring with inner ring contacts, cylinder rolling element is cylindrical shape, two end faces of cylinder rolling element are convex spherical, two spherical end surfaces of cylinder rolling element respectively with the interior edge face of outer ring and the exterior edge face point cantact of inner ring, cylinder rolling element close-packed arrays in toroidal cavity, contact with each other between adjacent column rolling element.The cylindrical roller end face of roller bearing of the present utility model is sphere, can prevent bearing in operation process, because roller body and the conical surface pass through mutually, causes the problem that string arc interference phenomenon occurs.
Description
Technical field
The utility model relates to technical field of bearings, is specifically related to a kind of roller bearing preventing string arc to interfere.
Background technique
At present, in heavy-duty machinery technical field, bearing is the core of this equipment, because it is except having supporting pole heavy load revolute function, also to bear great tilting moment, to adapt to the transhipment of remote heavily loaded goods, turntable bearing is because of its stronger bearing capacity in extensive use and large lifting equipment, roller bearing is when designing, good contact can be kept with inside and outside raceway for making roller, roller diameter is made to equal the width of raceway section, for the easy roller end face of manufacturing is plane, due to interior raceway relative to roller be male cone (strobilus masculinus) roller end face therewith the conical surface be linear contact lay, namely roller end face is on the tangential plane of the raceway conical surface, therefore roller end face conical surface generation interference therewith never.And outer raceway is inner conical surface relative to roller, in bearing operation process, easily cause roller body to pass through mutually with the conical surface, string arc interference phenomenon occurs.
Model utility content
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, and provides a kind of roller bearing preventing string arc to interfere.
The utility model is the deficiency solved the problems of the technologies described above, the technological scheme adopted is: a kind of roller bearing preventing string arc to interfere, comprise inner ring, outer ring and cylinder rolling element, the upper end of described outer ring and the lower end of inner ring all have rib, outer ring and the involutory rear Formation cross-section of inner ring are the toroidal cavity of rectangle, a circle cylinder rolling element is provided with in this toroidal cavity, each cylindrical roller axially all in annulus chamber in the radial direction, and the rib that the cylinder of each cylinder rolling element all contacts with outer ring with inner ring contacts, described cylinder rolling element is cylindrical shape, two end faces of cylinder rolling element are convex spherical, two spherical end surfaces of cylinder rolling element respectively with the interior edge face of outer ring and the exterior edge face point cantact of inner ring.Described cylinder rolling element close-packed arrays in toroidal cavity, contacts with each other between adjacent column rolling element.
beneficial effect
The cylindrical roller end face of roller bearing of the present utility model is sphere, can prevent bearing in operation process, because roller body and the conical surface pass through mutually, causes the problem that string arc interference phenomenon occurs.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of the utility model roller bearing;
Fig. 2 is the partial structurtes schematic diagram I of the utility model roller bearing;
Mark in figure: 1, inner ring, 2, outer ring, 3, cylinder rolling element, 4, toroidal cavity.
Embodiment
As shown in the figure: a kind of roller bearing preventing string arc to interfere, comprise inner ring 1, outer ring 2 and cylinder rolling element 3, the upper end of described outer ring 2 and the lower end of inner ring 1 all have rib, outer ring 2 and the involutory rear Formation cross-section of inner ring 1 are the toroidal cavity 4 of rectangle, a circle cylinder rolling element 3 is provided with in this toroidal cavity 4, cylinder rolling element 3 is close-packed arrays in toroidal cavity 4, contacts with each other between adjacent column rolling element 3.Each cylinder rolling element 3 axially all at toroidal cavity 4 in the radial direction, and the rib that the cylinder of each cylinder rolling element 3 all contacts with outer ring 2 with inner ring 1 contacts, described cylinder rolling element 3 is cylindrical shape, two end faces of cylinder rolling element 3 are convex spherical, two spherical end surfaces of cylinder rolling element 3 respectively with the interior edge face of outer ring 2 and the exterior edge face point cantact of inner ring 1.The cylindrical roller end face of roller bearing of the present utility model is sphere, can prevent bearing in operation process, because roller body and the conical surface pass through mutually, causes the problem that string arc interference phenomenon occurs.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
