Abstract
The utility model discloses a hollow roller used for an over-sized bearing, which comprises a bearing roller body (8). The center of the roller body (8) is provided with a through hole (1); the hollow rate of the through hole (1) which is the ratio between the diameter of the through hole and the outer diameter of the roller body (8) is 40 to 60 percent. The hollow roller has the advantages of high bearing capability, small contact stress, long fatigue life, convenient processing, good harden-ability performance, light weight, small eccentric force and small starting moment, etc.
Description
Technical field
The utility model belongs to technical field of bearings, and what relate generally to is the structural type of extra large size bearing with hollow roller.
Background technique
At present, China's dress is mainly used on the equipment such as mine, metallurgy, cement, wind-force water generating with the extra large size bearing of rolling element diameter more than or equal to 100 millimeters, because the applying working condition of these equipment is abominable, requires to be installed in bearing on these equipment and have the bearing capacity height, resistance to shock is good, running is steady, greasy property is good, the good advantages such as (to selfaligning roller bearing and self-aligning thrust roller bearings) of aligning performance.Because the major diameter roller of these bearings all adopts solid roller, the hardenability of material is poor during heat-treatment quenching, causes roller hardness to be difficult to the requirement of the standard that reaches, so that the bearing capacity of bearing descends, and causes bearing to lose efficacy in advance.
Summary of the invention
The purpose of this utility model provides the extra large size bearing hollow roller, makes it have characteristics such as bearing capacity height, contact stress is little, fatigue life is long.
The purpose of this utility model can adopt following technological scheme to realize: it comprises the roller body, and there is a through hole that runs through at the center of roller body; The hollow rate of through hole is that the ratio of through-hole diameter and this body diameter of roller (asymmetric roller is got the average diameter of roller body) is 40-60%.
For cylindrical roller and aligning roller, two symmetrical end faces of its body respectively do one concentric and join with through hole greater than the depression and the through hole of through-hole diameter; Respectively falling an angle at the through hole two ends for tapered roller is 60 ° chamfering, and roller small end face and chamfering are joined, roller large end face do one concentric and join with through hole greater than the depression and the chamfering of through-hole diameter; For the thrust force aligning roller respectively fall at the through hole two ends one be 60 ° chamfering with the end face angle of joining.
For the cylindrical roller and the tapered roller of perforating branches post in the middle of the through hole, be the frictional heating that reduces through hole and pillar, the length of its through hole is 1/2nd of roller length, and through hole is positioned at the centre of roller, and it is 10 ° bellmouth orifice that respectively there is an angle at the through hole two ends; Each joins two bellmouth orifices of cylindrical roller with the depression at two ends; Two bellmouth orifice one ends and the depression of tapered roller join, and an end and angle are that 60 ° chamfering is joined.
The hollow roller of the utility model design is easy to process, hardenability good, and has from heavy and light, advantage such as centrifugal force is little, starting torque is little.
