Description

A kind of inner ferrule gearing

Technical field

This utility model belongs to field of bearings, a kind of inner ferrule gearing.

Background technology

Bearing is to play parts that are fixing and that reduce load coefficient of friction in mechanical transmission course.It may also be said that when other When parts produce relative motion on axle each other, it is used for reducing the coefficient of friction in power transmission process and holding shaft center Fixing parts.Bearing is a kind of very important parts in plant equipment in the present age.Its major function is to support machinery rotation Turn, in order to reduce equipment mechanical load coefficient of friction in transmission process.

Bearing generally includes bearing outer ring and bearing inner race, is provided with between bearing outer ring and the bearing inner race of ball bearing Ball, is arranged in axle in bearing inner race during use so that it is fix with bearing inner race, and bearing outer ring is relative with bearing inner race to be turned Dynamic, to reach to reduce the purpose of friction.

The utility model of Application No. CN201420627240.X discloses a kind of bearing, including in bearing outer ring and bearing Circle, be radially disposed with several adjusting rings in bearing inner race, some adjusting rings are all coaxially disposed, some adjusting rings all with Bearing inner race links, and removably connects between some adjusting rings, regulates in bearing according to practical situations such as the diameter of axle Footpath size.

But bearing should be high degree of symmetry part, between the adjusting ring of this bearing and adjusting ring and adjusting ring and inner ring Relying on the Flange joint being arranged on bearing side to fix, bearing is when rotating, and inner ring is fixed with portion inside part, when inner ring rotates, First adjusting ring can be applied steering force, adjusting ring only uniquely relies on inner ring and is arranged on the flange of side and fixes, and therefore turns Xiang Lihui acts on flange, but flange is only provided in the side of bearing, therefore to cause unbalance stress, the side of flange Meeting increased wear, bearing easily damages, and reduces the service life of bearing；And while preventing adjusting ring from skidding, key and key Groove can be rotated in a circumferential direction the oppressing of power by a part, but the keyway of this bearing is only provided with at one, in the course of time, and bearing Also therefore serious wear compared to other positions, the service life of bearing can be significantly reduced at keyway.

Utility model content

For the deficiencies in the prior art, this utility model provides one and is provided by centrosymmetric inside race, and And the entirety of bearing is in a center of symmetry, and by the superposition from level to level of inside race, i.e. can realize bearing inner ring hole footpath Regulation, again because high degree of symmetry, uniform force, has longer service life, and reasonable in design, the inside race of simple in construction Bearing.

For achieving the above object, this utility model provides following technical scheme: a kind of inner ferrule gearing, including outer ring and Inner ring, is provided with retainer between inner ring and outer ring, retainer is provided with ball and it is characterized in that: described inner ring is the most successively Being equipped with several lassos, several lassos described are all provided with on inner ring coaxial linkage, and the circumference side of described lasso Several screwed holes, described lasso is the most symmetrical on central axis, and centrosymmetry in the circumferential.

Further, on the circumference side of described lasso, the place of corresponding screwed hole offers for accommodating the recessed of bolt head Groove.

Further, the inner ring face of described lasso offers several locating grooves, and described locating groove becomes center It is symmetrically distributed on lasso, the face, outer ring of corresponding lasso is provided with the positioning convex strip fastened with locating groove.

Further, described locating groove is interspersed with screwed hole.

Further, the edges and corners of described location card article are provided with fillet.

Compared with prior art, the beneficial effects of the utility model are:

1, by inside race and the setting of screwed hole so that lasso is tightened on inner ring by bolt, and superposition The bearing of complete lasso remains in that symmetrical on central axis, and keeps centrosymmetry in the circumferential；Such bearing Can change the size in inner ring aperture to adapt to the portion inside part of different radii size, and become high degree of symmetry, bearing makes During with rotation, each place uniform force of bearing, increase the service life, improve the service efficiency of bearing.

2, by the setting of groove, groove can accommodate the head of bolt, keeps the contact surface light of lasso and portion inside part Slide, and the socket of lasso will not be hindered, improve the matching property of bearing.

3, by positioning convex strip and the setting of locating groove, draw-in groove i.e. can convenient when dismounting lasso be installed, Er Qieke To share the power that rotates in a circumferential direction of a part, prevent the damage of bearing inner ring, and locating groove is in a center of symmetry, make axle equally The uniform force held, increases the service life.

4, by the setting of fillet so that positioning convex strip will not scratch the hands of operator when mounted, operative employee is improved The safety of people.
