Abstract
The utility model relates to a full-complement cylindrical roller bearing with a retainer. The cylindrical roller bearing comprises an outer ring and cylindrical rollers, wherein the inner surface of the outer ring is provided with a groove used for installing the cylindrical rollers. The cylindrical roller bearing is characterized by also comprising the cylindrical roller retainer connected with the outer ring; the cylindrical rollers are hinged on the retainer; and a clearance is reserved between two adjacent cylindrical rollers. The cylindrical rollers do not contact one another, and the clearance is reserved between the two adjacent cylindrical rollers; during working, a phenomenon of friction between the adjacent cylindrical rollers is avoided, so that the rotating speed of the full-complement cylindrical roller bearing is greatly increased; on the premise of meeting the requirement of heavy loading of the bearing, a relatively high operating speed in application is ensured; and compared with the conventional full-complement cylindrical roller bearing, the cylindrical roller bearing is characterized in that a self-locking device is eliminated in a designing process, the application area of the full-complement cylindrical roller bearing is expanded, and the full-complement cylindrical roller bearing has good economic benefits.
Description
Technical field
The utility model relates to a kind of bearing, is specifically related to a kind of full-complement cylinder roller bearing with retainer.
Background technique
Existing full-complement cylinder roller bearing is made up of outer ring and cylindrical roller; The internal surface of this outer ring is provided with the groove that supplies cylindrical roller to install; Between the groove of cylindrical roller and outer ring, also be provided with self-locking device; And adjacent setting of each cylindrical roller is so full-complement cylinder roller bearing only is applicable to heavy load and the relatively low occasion of rotating speed.
And for requiring the application that load is heavier and rotating speed is high, local spot corrosion occurs, peel off through regular meeting in this full-complement cylinder roller bearing running, catastrophe failures such as roller fragmentation also can appear when serious; Owing to being in contact with one another between the roller and rotating in the opposite direction at surface of contact; Make the lubricating film between the roller be difficult to form, will inevitably produce a large amount of frictional heats, make the cylindrical roller serious wear; Thereby cause the too early inefficacy of bearing, the working life of having reduced full-complement cylinder roller bearing.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of full-complement cylinder roller bearing of the band retainer that is applied to the higher occasion of rotating speed and grows working life.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of full-complement cylinder roller bearing with retainer; Comprise outer ring and cylindrical roller, the internal surface of this outer ring is provided with the groove that supplies cylindrical roller to install, and it is characterized in that: also include the cylindrical roller retainer that is connected with the outer ring; Described cylindrical roller is articulated on the retainer, has the gap between the adjacent cylindrical roller.
Through adopting technique scheme, do not contact between the cylindrical roller, there is the space; In the course of the work, avoid the phase mutual friction, improved the rotating speed of full dress cylindrical bearing greatly; Satisfying under the prerequisite that bearing bears the heavy load requirement, can satisfy the higher relatively application of motion speed again, and existing relatively full-complement cylinder roller bearing has omitted this link of design self-locking device; Widen the application of full-complement cylinder roller bearing, had good economic benefit.
The utility model further is set to: the part of described cylindrical roller falls in the groove of outer ring; Another part is positioned at outside the groove of outer ring; The center of the axial both ends of the surface of described cylindrical roller is provided with pit, and retainer is provided with the boss suitable with pit.
Through adopting technique scheme, through roller bearing retainer and outer ring to be fixed, such means of fixation is simple, and is easy to realize.
The utility model also further is set to: described retainer is a plate-like framework; Comprise a side face; The two edges of this side face are vertically installed with side plane; The center of two side planes is provided with corresponding axis hole, part between the edge of this axis hole and the edge of side face constitute side face along the limit, described boss is positioned at along on the madial wall on limit; Described side face is provided with some and the suitable through hole of cylindrical roller, and the part of described cylindrical roller is passed through hole and contacted with the bottom surface of outer ring groove.
Through adopting technique scheme, such retainer only is arranged at intervals with through hole at side face, has both guaranteed not contact between the adjacent cylindrical roller, has guaranteed the intensity of retainer again.
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
