Abstract
Gig running roller, comprises running roller body, and running roller body interior is the structure of hollow, and described running roller body internal surface two ends are provided with the boss of ring-type, are provided with needle roller between two boss, and needle roller is circumferentially in running roller body internal surface, and needle roller is fastened between two boss; Rolling axle is provided with in described running roller body.The utility model bearing load is large; Long service life.
Description
Technical field
The utility model relates to a kind of gig running roller.
Background technology
Gig is the heavy mechanical equipment being undertaken transporting by changing potential energy.At present, in gig running roller, be deep groove ball bearing structure, by deep groove ball bearing and rolling axle with the use of.This type of gig running roller load is less, if the load of carrying exceedes peak load value, will affect the service life of roller.Meanwhile, the rolling axle of this type of gig running roller does not have oil hole, inconvenient oiling; In addition, the rolling axle of this type of gig running roller all adopts carbon round steel to make, and service life is shorter.
Utility model content
Technical problem to be solved in the utility model is, overcomes the deficiency of above-mentioned background technology, provides that a kind of bearing load is large, the gig running roller of long service life.
The technical scheme that the utility model solves the employing of its technical matters is, a kind of gig running roller, comprise running roller body, running roller body interior is the structure of hollow, described running roller body internal surface two ends are provided with the boss of ring-type, be provided with needle roller between two boss, needle roller is circumferentially in running roller body internal surface, and needle roller is fastened between two boss; Rolling axle is provided with in described running roller body.
Further, described rolling axle is provided with oil hole.
Further, the length of described rolling axle is 50 ~ 70mm.
Further, the quantity of described needle roller is 10 ~ 30.
Further, described rolling axle adopts bearing steel to make.
Compared with prior art, advantage of the present utility model is as follows: (1) running roller body internal surface two ends are provided with the boss of ring-type, are provided with needle roller between two boss, by needle roller and rolling axle with the use of, the load of carrying is large, and service life is longer; (2) rolling axle is provided with oil hole, facilitates oiling; (3) rolling axle adopts bearing steel to make, and can improve service life.
