Description

A kind of machine spindle bearing bearing with damping performance

Technical field

The utility model is related to a kind of machine bearing, specially a kind of machine spindle bearing bearing with damping performance, Belong to machine tool accessory technical field.

Background technology

Bearing is a kind of important spare part in contemporary plant equipment, and its major function is the mechanical rotary body of support, reduction Coefficient of friction in its motion process, and ensure its rotating accuracy, by the difference of motor element frictional property, bearing can be divided into rolling Dynamic bearing and the major class of sliding bearing two, and lathe is widely used as a kind of machine of manufacture instrument, the running of lathe also from Bearing is not driven, bearing plays important role in the accessory of lathe.And current machine spindle bearing bearing is typically adding Enter cumbersome, inconvenience during lubricating oil, Bearing inner in running, and bearing inner race and rotating shaft operating when, can all have Frictional dissipation between larger vibrations, and bearing internal external circle is than larger, and whole service life will be reduced, therefore, for Above mentioned problem proposes a kind of machine spindle bearing bearing with damping performance.

Utility model content

The purpose of this utility model is that provides a kind of machine spindle with damping performance to solve the above problems Bearing bearing.

The utility model is achieved through the following technical solutions above-mentioned purpose, a kind of machine spindle bearing with damping performance Set with bearing, including outer ring, on the outer ring has oil filler point through the outer ring；Groove is provided with the inside of the outer ring； The side of the groove is provided with flexible rings；The side of the flexible rings is roller；Retainer is socketed with the roller；It is described Flexible rings are arranged on the groove on the inside of inner ring；It is provided between the inner ring and the outer ring positioned at the retainer one The dust cap of side；Damping silica gel is provided with the outside of the inner ring.

It is preferred that, in order that the overall service precision of bearing is higher, opened on the outer ledge of the outer ring and the inner ring There is chamfering.

It is preferred that, in order that the right and left can sealed dustproof, the symmetrical outer ring of dust cap and described simultaneously Inner ring is provided with two.

It is preferred that, in order that rotating shaft and inner ring 3 are contacted closely, be machined with knurling on the outer surface of the damping silica gel.

It is preferred that, in order that installing simple and retentivity preferably, the retainer is rivet type retainer.

It is preferred that, in order that damping silica gel has preferable stability on inner ring, the damping silica gel is viscous by adhesive Knot is on the outside of the inner ring.

The beneficial effects of the utility model are：The machine spindle bearing that this kind has damping performance is provided with bearing on outer ring The oil filler point through outer ring facilitate carry out injection lubricating oil to whole Bearing inner, it is convenient and time-saving, while again effective The stability of inner rotation is improved, the frictional dissipation of inside is reduced, and dust cap between bearing internal external circle can be effective Prevent external dust from entering inside and causing obstruction, and provided with the flexibility with roller contact on the groove on the inside of inner ring and outer ring Circle, reduces roller noise in the running and also has buffering effect, while avoiding roller and inner ring, the groove of outer ring are straight Contact, also avoids them and directly rubs, it is to avoid loss, improve service life, on the outside of the inner ring on it is glued Damping silica gel can increase the friction of the contact with grafting rotating shaft, reduce the vibrations of inner ring and grafting rotating shaft in the running, this Machine spindle bearing with damping performance with bearing using easy to operate, while there is damping, the characteristic of frictional dissipation is reduced, and Service life is long.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

Refer to shown in Fig. 1-2, a kind of machine spindle bearing bearing with damping performance, including outer ring 1, on outer ring 1 Set has oil filler point 2 through outer ring 1；The inner side of outer ring 1 is provided with groove 8；The side of groove 8 is provided with flexible rings 9；Roller 7 On be socketed with retainer 6；The side of roller 7 is flexible rings 9；Flexible rings 9 are arranged on the groove 8 of the inner side of inner ring 3；The He of inner ring 3 The dust cap 5 positioned at the side of retainer 6 is provided between outer ring 1；Damping silica gel 4 is provided with the outside of inner ring 3.

Chamfering is provided with the outer ledge of outer ring 1 and inner ring 3, it is ensured that the overall service precision of bearing is higher；Dust cap 5 Symmetrical outer ring 1 and inner ring 3 are provided with two, and the right and left can be while sealed dustproof；Processed on the outer surface of damping silica gel 4 There is knurling, increase contact friction so that rotating shaft and inner ring 3 are contacted closely；Retainer 6 is rivet type retainer, installs simple And retentivity is preferable；Damping silica gel 4 is bonded in by adhesive on the outside of inner ring 3, it is ensured that damping silica gel 4 is on inner ring 3 Stability.
