Embodiment Construction

[0018] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] As shown in the figure, a needle-roller-ball combined rolling element for a bearing includes two connected identical needle rollers 1 and several rolling balls 2 placed between the two needle rollers 1 .

[0020] The two connected needle roller bodies 1 are movably connected.

[0021] The contact position between the needle roller body 1 and the rolling ball body 2 has a groove structure matching with the rolling ball body 2 .

[0022] The two identical needle roller bodies 1 are connected by a connecting rod, and there are several oil grooves 3 on the connecting rod.

[0023] There is a gap between the rolling ball body 2 and two adjacent needle roller bodies 1 .

[0024] The roller body 2 is fixed between two needle roller bodies 1, and the contact between the needle roller body 1 and the roller body 2 has a groove stru...

Abstract

The invention discloses a rolling needle and rolling ball combined rolling body for a bearing. The rolling body comprises two same rolling needle bodies and multiple rolling ball bodies, wherein the two rolling needle bodies are connected and the rolling ball bodies are arranged between the two rolling needle bodies. Compared with the prior art, the rolling needle type rolling bodies and rolling ball type rolling bodies of the bearing are combined and three stress points contact an outer ring and an inner ring of the bearing simultaneously, so that the bearing has strong wear resistance and can still rotate when the rolling needle bodies or the rolling ball bodies are damaged.

Description

technical field [0001] The invention relates to an inner rolling body of a bearing, in particular to a needle-roller-ball combined rolling body for a bearing. Background technique [0002] In the past, the rotary bearings were mostly composed of inner rings, rolling elements and outer rings. The rolling elements are generally needle rollers or balls. The needle rollers are a cylindrical structure and are a whole. Under long-term rotation and friction, once damaged , the whole body cannot rotate, or even get stuck in the outer ring and inner ring, and wear the inner and outer rings, causing greater damage. The rotation of the rolling ball is relatively tight, the contact surface between the ball and the inner and outer rings is small, and the relative pressure is greater. It will not play its original role at all and lose its support. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a needle-roller-ball comb...
