Description
Technical Field
The utility model mainly relates to the field of auxiliary bearings, in particular to a roller for a slewing bearing.
Background
For long shafts of various large-scale load equipment in the industries of petroleum, chemical industry, pharmacy, food, metallurgy and the like, in order to prevent the phenomenon that the equipment is unstable in operation and further causes the damage of the related equipment due to the swing of the long shaft,
the prior art generally adopts the arrangement of a middle bearing or a bottom bearing to play a role of auxiliary supporting for a long shaft, and because the middle bearing or the bottom bearing only plays a role of auxiliary supporting for the long shaft, most of sliding bearings placed in equipment depend on self lubrication of materials due to poor lubrication conditions, the sliding bearings are easy to wear, and have higher requirements on lubrication and maintenance.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model provides a roller for a slewing bearing, which comprises a ball body 1 and an annular hollow oil storage cavity 2 arranged in the ball body 1, wherein an oil outlet 3 connected to the oil storage cavity 2 is arranged on the ball body 1,
the ball bearing comprises a ball body 1 and is characterized in that a sleeve 4 and two bearings 5 are sleeved on the side wall of the ball bearing body 1, the two bearings 5 are respectively located at two ends of the sleeve 4, a bearing seat 6 is arranged between each bearing 5 and the corresponding sleeve 4, and the sleeve 4 is fixedly connected with the outer ring of each bearing 5 through the corresponding bearing seat 6.
Preferably, the inner ring of the bearing 5 is sleeved on the side wall of the ball body 1 by adopting an embedded installation method.
Preferably, a clamp spring 7 for fixing an inner ring of the bearing 2 is arranged at one end, far away from the oil storage cavity 2, of the bearing 5.
Preferably, the lateral wall of the ball body 1 is further sleeved with two side vertical plates 8, and the two side vertical plates 8 are respectively arranged at two ends of the sleeve 4.
Preferably, the side vertical plate 8 is fixedly connected with the bearing seat 6 through a bolt device.
Preferably, the oil outlet holes 3 are provided in plurality at equal intervals in the circumferential direction of the oil storage chamber 2.
The utility model has the beneficial effects that:
through seting up the oil outlet in that the ball body is inside, can reach the effect of self-lubricating at the oil outlet at the operation in-process, set up two bearings, the sleeve passes through the bearing frame to be connected fixedly with the outer lane of a shaft, and the embedding of bearing inner race has reduced the coefficient of friction of ball body at the operation in-process on the ball body, not only easily lubricates but also simple structure, and maintenance cost is lower.
