Abstract

The utility model discloses a kind of cylinder roller bearing retainer to guide new construction, it includes outer ring, inner ring, rolling element and retainer, when cylinder roller bearing is that NU, NJ profile shaft are held, reduce the symmetrical annular retainer internal diameter size in both sides, the circular inside diameters size and the roller surface of the inner ring for making the retainer are adapted, and the guide surface of retainer is used as using the roller surface of the inner ring；When cylinder roller bearing is that N, NF profile shaft are held, increase the symmetrical annular retainer outside dimension in both sides, the annular outside dimension and the roller surface of the outer ring for making the retainer are adapted, and the guide surface of retainer is used as using the roller surface of the outer ring.The utility model, which avoids, lacks lubricating oil phenomenon between retainer and bearing ring, retainer guide surface is in oil film state all the time, reduces retainer abrasion, reduces vibration, reduce noise, improves bearing service life.

Description

Cylinder roller bearing retainer guides new construction

Technical field：

A kind of bearing and retainer are the utility model is related to, is guided more particularly to a kind of cylinder roller bearing retainer new Structure.

Background technology：

It is well known that in bearing industry, retainer guidance mode has three kinds：1. inner ring internal-and external diameter guides retainer Internal diameter（Shown in Fig. 7 and Fig. 8）, internal diameter guiding retainer external diameter outside 2. outer rings（Shown in Fig. 5 and Fig. 6）, the guiding holding of 3. rolling elements Frame pocket hole（The bearing slow-speed of revolution is only limited to use）, thereon 1 or 2 modes easily make guide surface lack lubricating oil, cause retainer to grind Damage is serious, raises bearing temperature, and causes vibration and noise, causes bearing failure.Professional is looking for feasible side always Method, inherently one of hang-up, and the bearing professional problem to be solved and never solved.

Utility model content：

Technical problem to be solved in the utility model is：Overcome the deficiencies in the prior art, there is provided one kind is reasonable in design, subtracts Few retainer abrasion and the cylinder roller bearing retainer guiding new construction for reducing noise.

The technical solution of the utility model is：

A kind of cylinder roller bearing retainer guides new construction, including outer ring, inner ring, rolling element and retainer, cylinder rolling When sub- bearing is that NU, NJ profile shaft are held, the symmetrical annular retainer internal diameter size in both sides is reduced, makes the circular inside diameters chi of the retainer The very little roller surface with the inner ring is adapted, and the guide surface of retainer is used as using the roller surface of the inner ring；Cylinder roller bearing When being held for N, NF profile shaft, increase the symmetrical annular retainer outside dimension in both sides, make annular outside dimension and the institute of the retainer The roller surface for stating outer ring is adapted, and the guide surface of retainer is used as using the roller surface of the outer ring.

When cylinder roller bearing is that NU, NJ profile shaft are held, the circular inside diameters of the retainer are reduced in size to than the inner ring The big 0.25--0.6mm of raceway size；When cylinder roller bearing is that N, NF profile shaft are held, the annular outside dimension of the retainer increases Greatly to smaller 0.3--0.9mm than the raceway size of the outer ring.

The beneficial effects of the utility model are：

1st, the utility model, which avoids, lacks lubricating oil phenomenon between retainer and bearing ring, guide retainer

Face is in oil film state all the time, reduces retainer abrasion, reduces vibration, reduce noise, improves bearing service life.

2nd, in the running, imported bearing level has been fully achieved in the utility model product in terms of vibration, noise, for production Enterprise reduces bearing use cost, obtains the consistent accreditation of user, and its applicability is very high, implementation easy to spread, has good Good economic benefit.

Embodiment：

Embodiment：Referring to Fig. 1-Fig. 8, in figure, 01- outer rings, 02- inner rings, 03- retainers, 04- rolling elements, 5- retainers Guide surface.

Cylinder roller bearing retainer guides new construction, including outer ring 01, inner ring 02, rolling element 04 and retainer 03, its In：When cylinder roller bearing is that NU, NJ profile shaft are held, the symmetrical annular retainer internal diameter size in both sides is reduced, makes the ring of retainer 03 The roller surface of shape internal diameter size and inner ring 02 is adapted, the guide surface 05 using the roller surface of inner ring 02 as retainer；Cylinder rolls When sub- bearing is that N, NF profile shaft are held, increases the symmetrical annular retainer outside dimension in both sides, make the annular outside dimension of retainer 03 It is adapted with the roller surface of outer ring 01, the guide surface 05 using the roller surface of outer ring 01 as retainer.

When cylinder roller bearing is that NU, NJ profile shaft are held, the circular inside diameters of retainer 03 are reduced in size to the rolling than inner ring 02 The big 0.25--0.6mm of road size；When cylinder roller bearing is that N, NF profile shaft are held, the annular outside dimension of retainer 03 increases to ratio The small 0.3--0.9mm of raceway size of outer ring 01.

The utility model, which avoids, lacks lubricating oil phenomenon between retainer and bearing ring, retainer guide surface is begun

Oil film state is in eventually, is reduced retainer abrasion, is reduced vibration, reduce noise, improves bearing service life.

It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal Limitation, every any simple modification made according to the technical essence of the utility model to above example, equivalent variations with Modification, in the range of still falling within technical solutions of the utility model.

Claims

1. a kind of cylinder roller bearing retainer guides new construction, including outer ring, inner ring, rolling element and retainer, it is characterized in that： When cylinder roller bearing is that NU, NJ profile shaft are held, the symmetrical annular retainer internal diameter size in both sides is reduced, makes the annular of the retainer The roller surface of internal diameter size and the inner ring is adapted, and the guide surface of retainer is used as using the roller surface of the inner ring；Cylinder rolls When sub- bearing is that N, NF profile shaft are held, increases the symmetrical annular retainer outside dimension in both sides, make the annular outer diameter ruler of the retainer The very little roller surface with the outer ring is adapted, and the guide surface of retainer is used as using the roller surface of the outer ring.
