Description

Bearing

Technical field

The utility model relates to component of machine fields, in particular to bearing.

Background technique

Bearing refers to plays component that is fixed and reducing load coefficient of friction in mechanical transmission course.When other parts are in axis On when generating relative motion each other, bearing can be used to reduce coefficient of friction in power transmission process and holding shaft center is solid It is fixed.Therefore, bearing is a kind of very important components in contemporary mechanical equipment.Its major function is the mechanical rotation of support Body, to reduce mechanical load coefficient of friction of the equipment in transmission process.

Currently, bearing is by outer ring, inner ring and is fixed on the rolling element between outer ring and inner ring by retainer and forms, It has the following deficiencies: first is that bearing at runtime can be by the relatively high speed rotation of rolling element, in order to subtract between outer ring and inner ring The abrasion of few Bearing inner needs artificial frequently addition lubricating oil to be lubricated bearing, and cumbersome and lubricant effect is not It is good；Second is that extraneous sundries and dust is easily accessible Bearing inner outside being exposed between the outer ring and inner ring two sides of bearing, aggravation Abrasion between rolling element and outer ring and inner ring, to influence the service life of bearing, or even directly results in bearing damage；Three It is the outer ring of bearing and inner ring is integrated setting, when Bearing inner breaks down or needs to clear up, bearing is torn open Dress is inconvenient.

Utility model content

In view of the shortcomings of the background art, the utility model provides bearing, and the technical problem to be solved is that such as What keeps bearing dismantling convenient and efficiently reduces the abrasion of Bearing inner.

To reach the purpose of this utility model, the technical solution adopted is that: bearing, inner ring including coaxial arrangement and outer Circle, the inner ring by be detachably connected first in half-turn and second half-turn form, the outer ring by be detachably connected the One outer half-turn and the second outer half-turn composition, the middle part of the outer peripheral surface of the inner ring is equipped with the first raceway, the inner circumferential of the outer ring The middle part in face is equipped with the second raceway corresponding with the first raceway, is formed and is put between first raceway and second raceway Slot is set, matched several spherical balls are equipped in the placing groove, each spherical ball is equipped with shoe cream room, described The outer peripheral surface of spherical ball is equipped at least one through-hole being connected to the shoe cream room, and the two sides of the outer ring are equipped with detachable Annular dustproof cover, each annular dustproof cover covers the placing groove, the inner face and the inner ring of the annular dustproof cover There are gaps for side.

It is uniformly provided with the first bolt hole on the side of the outer ring, is offered and described first on the annular dustproof cover The second bolt hole that bolt hole matches, first bolt hole are connect with second bolt hole by bolt thread.

The inner peripheral surface of the connecting pin of half-turn is equipped with the first U-type groove in described first, the connecting pin of half-turn in described second Inner peripheral surface be equipped with the second U-type groove, second U-type groove is corresponding with first U-type groove, first U-type groove and institute State and be equipped with the first link block in the second U-type groove, first link block respectively with first U-type groove and second U-type groove It is threadedly coupled.

The outer peripheral surface of the connecting pin of the first outer half-turn is equipped with third U-type groove, the connecting pin of the second outer half-turn Outer peripheral surface be equipped with the 4th U-type groove, the third U-type groove is corresponding with the 4th U-type groove, the third U-type groove and institute State and be equipped with the second link block in the 4th U-type groove, second link block respectively with the third U-type groove and the 4th U-type groove It is threadedly coupled.

Acquired beneficial effect is the utility model compared with the existing technology: by carrying oil storage inside spherical ball Chamber, and its outer peripheral surface is equipped with the through-hole being connected to shoe cream room, during rotation, the oily meeting due to centrifugal action, in shoe cream room It is thrown out of and in slave through-hole slowly, realize the effect of lubrication, to reduce the abrasion of Bearing inner, improve bearing Service life；By installing the dustproof cover of covering placing groove in the two sides of bearing, sundries and some mechanical ashes are effectively prevented Dirt enters Bearing inner, it is avoided to cause to wear to Bearing inner, further improves the service life of bearing；By by bearing Outer ring and inner ring be set to be detachably connected two half-turns and form, realize the convenient technical effect of bearing dismantling.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

The present invention will be further described with specific embodiment with reference to the accompanying drawings of the specification.

Bearing as shown in Figure 1:, inner ring 1 and outer ring 2 including coaxial arrangement, inner ring 1 by be detachably connected first in half Half-turn composition in circle and second, in this way setting are convenient to dismount outer ring 2 and inner ring 1, and then conveniently carries out to Bearing inner Maintenance, in this implementation column, the inner peripheral surface of the connecting pin of half-turn is equipped with the first U-type groove in first, the connection of half-turn in second The inner peripheral surface at end is equipped with the second U-type groove, and the second U-type groove is corresponding with the first U-type groove, sets in the first U-type groove and the second U-type groove There is the first link block, the first link block is threadedly coupled with the first U-type groove and the second U-type groove respectively.Outer ring 2 is by being detachably connected First outer half-turn and the second outer half-turn composition, in the present embodiment, the outer peripheral surface of the connecting pin of the first outer half-turn is equipped with the 3rd U The outer peripheral surface of type groove, the connecting pin of the second outer half-turn is equipped with the 4th U-type groove, and third U-type groove is corresponding with the 4th U-type groove, the The second link block is equipped in three U-type grooves and the 4th U-type groove, the second link block connects with third U-type groove and the 4th U-type groove screw thread respectively It connects.The middle part of the outer peripheral surface of inner ring 1 is equipped with the first raceway 3, and the middle part of the inner peripheral surface of outer ring 2 is equipped with and 3 phase of the first raceway Corresponding second raceway 4 forms placing groove 5, is equipped in placing groove 5 matched between first raceway 3 and the second raceway 4 Several spherical balls 6, each spherical ball 6 are equipped with shoe cream room, and the outer peripheral surface of spherical ball 6 is equipped at least one and shoe cream room The through-hole 8 of connection, during rotation, due to centrifugal action, the oil in shoe cream room can be thrown out of bearing in slave through-hole 8 slowly Come, makes to have obtained sufficient lubrication between spherical ball 6 and placing groove 5, reduce the friction of Bearing inner, to reduce axis Internal abrasion is held, the service life of bearing is improved.The two sides of outer ring 2 are equipped with dismountable annular dustproof cover 9, removably Setting is convenient to dismount annular dustproof cover 9, so that convenient cleaned and replaced to annular dustproof cover 9, in the present embodiment In, it is uniformly provided with the first bolt hole on the side of outer ring 2, offers on annular dustproof cover 9 and match with the first bolt hole Second bolt hole, the first bolt hole are connect with the second bolt hole by bolt thread.Each annular dustproof cover 9 covers placing groove 5, Setting effectively prevents sundries in this way and dust enters Bearing inner, avoids it from causing to wear to Bearing inner, further mentions The high service life of bearing, there are gap, such setting ensure that axis for the inner face of annular dustproof cover 9 and the side of inner ring 1 Hold normal operation.
