Embodiment
Be described in detail to characteristic sum principle of the present utility model below in conjunction with accompanying drawing 1-7, illustrated embodiment, only for explaining the utility model, not limits protection domain of the present utility model with this.
As shown in Figure 2, Figure 3, Figure 4, for the dismounting schematic diagram of this model utility, comprise retainer body 1 and cylindrical roller 3, different from the entity structure of original retainer body 1 ' (as shown in Figure 1), this retainer also comprises except retainer is originally external the collar 2 coordinated with it.Retainer body is evenly provided with some pocket holes 4 for installing cylindrical roller for one week along retainer body outer peripheral surface, pocket hole is the circular hole of the radial direction evenly processing on retainer outer peripheral surface along retainer, wherein the diameter of circular hole is greater than the thickness of retainer, and therefore circular hole all has opening at the upper and lower surface of retainer; Cylindrical roller exposes pocket hole from this opening part.
As shown in Figure 5, Figure 6, further, be provided with the step-like bead 5 of annular at retainer body outer peripheral surface, what coordinate with this bead is the collar 2 with the annular of bead.The diameter of the collar and the diameter of retainer body outer peripheral surface are suitable, namely circumferential collar bead and the bead on retainer body by both the careful design of sizes process the tight interference fit that can realize between the two.
Do not have this structure of bead to be suitable for the less bearing of retainer body diameter, because now retainer is mainly used in small-sized cylindrical roller thrust bearing, impact shock amplitude is little; In addition because size is relatively little, bead is relatively not easily processed.By the circular hole of radial design upper and lower opening on retainer body as pocket hole, and the collar of annular is set at retainer outer peripheral surface, pocket hole coordinates with the collar and is fixed in pocket hole by cylindrical roller, circular hole and cylindrical roller are that face contacts, therefore cylindrical roller up and down scope in pocket hole is little, as shown in Figure 7, makes there is certain hole distance between retainer and blowout patche or base, therefore no longer there is serious fretting wear in retainer and blowout patche 8 or base 9, and the retainer life-span is improved.It is relatively above-mentioned not with the medium-sized retainer that the retainer diameter of bead is larger that retainer with bead is then suitable for retainer body diameter, because now to be mainly applicable to impact shock amplitude relatively large for retainer, and retainer body dimension larger processing bead is also relatively easy, the cooperation of bead makes the powerful enhancing of retainer entirety, not yielding, the life-span improves.
In order to ensure that the collar and the tight of retainer body are fixed, be evenly provided with some volume pins 6 in collar radial direction.
Further, for large-scale cylindrical roller thrust bearing, impact shock suffered by retainer is large, is therefore provided with protruding lacing wire 7 at retainer inner peripheral surface edge, and the circumferential surface edge of the collar is also provided with protruding lacing wire.The lacing wire of the projection arranged at the edge of retainer inner peripheral surface edge and the collar makes the intensity of retainer be improved, not yielding, the life-span improve while also make that lubricant oil or lubricating grease can be more lasting be kept on retainer, high lubricating effect.
Embodiment recited above is described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; relevant technical staff in the field, to various distortion of the present invention and improvement, all should expand in protection domain as determined in claims of the present invention.
