Abstract
The invention discloses a cylindrical roller bearing with a filling hole formed in the end surface. The cylindrical roller bearing comprises an inner ring and an outer ring, wherein an annular rectangular groove is formed in the outer side surface of the inner ring; another annular rectangular groove, the direction of which is opposite to that of the inner ring groove and the size of which is the same with that of the inner ring groove, is formed in the inner side surface of the outer ring; after the outer ring and the inner ring are sleeved and aligned, the two grooves are combined to form an annular rectangular roller path; multiple cylindrical rollers are filled in the annular rectangular roller path; inner and outer notches are separately formed in the end surface in which the inner ring and the outer ring are combined; with the midpoint of the combining seam of the inner ring and the outer ring as the center, the inner and outer notches form roller filling holes; after being filled with rollers, the roller filling holes are respectively blocked by two locking blocks. The cylindrical roller bearing is reasonable and reliable in structure and wide in application scope, and can be applied to a relatively large or small roller bearing; the two locking blocks are not separated from the respective end surfaces under any circumstance and need not screws or through pins to fasten, so that the roller bearing meets an aesthetic simple and straightforward appearance.
Description
Technical field
The present invention relates to engineering goods part field, specifically a kind of end face arranges the roller bearing of filling hole.
Background technique
Bearing is the vitals of supporting axle, and its effect is the working position of retainer shaft, the running accuracy of assurance axle and the friction factor that reduces axle.Bearing is divided into sliding bearing and the large class of rolling bearing two by friction type difference.The kind that rolling bearing is pressed rolling element is different, is divided into ball bearing (rolling element is steel ball) and roller bearing (rolling element is roller).Roller bearing is pressed roller kind, is divided into again: roller bearing, tapered roller bearing, needle bearing etc.But existing roller bearing or can only be applied to larger roller bearing, or can only be applied to less roller bearing, application area is single.
Summary of the invention
The object of this invention is to provide the roller bearing that a kind of end face arranges filling hole, can be applicable to larger roller bearing, also can be applicable to less roller bearing.
Technological scheme of the present invention is as follows:
A kind of end face arranges the roller bearing of filling hole, include inside and outside circle, it is characterized in that: the outer side surface of described inner ring is provided with ring-type rectangular recess, the inner side surface of described outer ring is provided with ring-type rectangular recess identical with inner ring groove size but opposite direction, described outer ring and inner ring be nested and neat after, described two grooves are merged into ring-type rectangle raceway, in described ring-type rectangle raceway, are filled with several cylindrical rollers; On an end face of described inside and outside circle combination, be respectively equipped with inside and outside breach, described inside and outside breach forms roller filling hole centered by the mid point of the bonding crack of described inside and outside circle, described roller filling hole is after completing roller filling, respectively by two lock dog shutoff.
Described end face arranges the roller bearing of filling hole, it is characterized in that: two described lock dogs are identical with the shape of inside and outside breach that forms roller filling hole respectively, and the processing dimension of two lock dogs respectively correspondence be greater than the about 0.01mm of inside and outside breach.
Described end face arranges the roller bearing of filling hole, it is characterized in that: described roller filling hole be shaped as circle, rectangle, two arch, internal moment outer ring or interior arch outer ring.
Beneficial effect of the present invention:
The present invention is rational in infrastructure, reliable, can be applicable to larger roller bearing, also can be applicable to less roller bearing, applied range, not separated with end face separately under two any operational conditions of lock dog, without with screw or wear and lock admittedly, guaranteed that roller bearing meets the profile of aesthetic brevity and lucidity.

Embodiment
Referring to accompanying drawing 1, a kind of end face arranges the roller bearing of filling hole, in including, outer ring 1, 2, in, outer ring 1, 2 height equates, the outer side surface of inner ring 1 is provided with ring-type rectangular recess 3, the inner side surface of outer ring 2 is provided with the measure-alike of ring-type rectangular recess 3 but the ring-type rectangular recess 4 of opposite direction, outer ring 2 be nested with inner ring 1 and neat after, ring-type rectangular recess 3, 4 are merged into ring-type rectangle raceway 5, in ring-type rectangle raceway 5, be filled with some cylindrical rollers 6, wherein, ring-type rectangular recess 3, 4 the degree of depth equals respectively the radius of some cylindrical rollers 6, ring-type rectangular recess 3, 4 width is greater than respectively the height of some cylindrical rollers 6, ring-type rectangular recess 3, 4 respectively distance in, outer ring 1, 2 upper, the size of lower end surface equates.On an end face of inside and outside circle 1,2 combinations, be respectively equipped with inside and outside breach, inside and outside breach forms roller filling hole 7 centered by the mid point of the bonding crack of inside and outside circle 1,2, roller filling hole 7 is after completing roller filling, respectively by 8,9 shutoff of two lock dogs, two lock dogs 8,9 are identical with the shape of inside and outside breach that forms roller filling hole 7 respectively, and the processing dimension of two lock dogs 8,9 respectively correspondence is greater than the about 0.01mm of inside and outside breach, under any operational condition, two lock dogs 8,9 are never separated with the breach at place separately.
Referring to accompanying drawing 2～6, in the present invention, roller filling hole 7 be shaped as circle, rectangle, two arch, internal moment outer ring or interior arch outer ring, its object is also in order to make two lock dogs 8,9 can block the jail breach at place separately.
Claims (3)
1. an end face arranges the roller bearing of filling hole, include inside and outside circle, it is characterized in that: the outer side surface of described inner ring is provided with ring-type rectangular recess, the inner side surface of described outer ring is provided with ring-type rectangular recess identical with inner ring groove size but opposite direction, described outer ring and inner ring be nested and neat after, described two grooves are merged into ring-type rectangle raceway, in described ring-type rectangle raceway, are filled with several cylindrical rollers; On an end face of described inside and outside circle combination, be respectively equipped with inside and outside breach, described inside and outside breach forms roller filling hole centered by the mid point of the bonding crack of described inside and outside circle, described roller filling hole is after completing roller filling, respectively by two lock dog shutoff.
