Abstract

The utility model relates to a retainer of a single-row cylindrical roller bearing. The retainer comprises a retainer seat and a retainer cover, wherein the retainer seat and the retainer cover are fixedly connected, the retainer seat comprises a plurality of support beams, the inner side of each support beam is provided with a groove, and a plurality of grooves form a circle of grooves at the inner diameter of the retainer seat. The inner diameter surface of the retainer seat of the single-row cylindrical roller bearing is provided with a circle of grooves, the grooves can realize the effects of storing dust and oil and ensuring the bearing lubrication effect, and the efficacy of flexible rotation of the bearing is ensured. In addition, raw materials can also be saved, the retainer of the single-row cylindrical roller bearing is generally a turned brass retainer, through the retainer with the grooves at the inner diameter, the raw materials of copper are greatly saved, and the production cost is reduced. The bearing retainer structure has the advantages that the friction can be reduced, the effects of oil storage and lubrication can also be realized, and the retainer can be widely applied to the single-row cylindrical roller bearings having types such as NU, NJ, N, NUP and NF.

Description

A kind of retainer of single row roller bearing

Technical field

The utility model belongs to the retainer field, particularly a kind of retainer of single row roller bearing.

Background technique

The retainer of traditional single row roller bearing, maintenance stand and retainer lid for the entity brass of car system connect with rivet, play a part to separate and guide rolls.

If but on-stream bearing load is too small, can produce between the roller of single row roller bearing and the raceway and slide, cause friction.The big large-scale single row roller bearing of roller and retainer weight particularly.

The model utility content:

The purpose of the utility model provides a kind of retainer of single row roller bearing, and this retainer reduces the slip between roller and the raceway keeping the stand internal diameter to offer a circle groove, but oil storage storage dirt, and the copper that saves material, reduced cost of production.

The technological scheme that adopts is:

A kind of retainer of single row roller bearing comprises the maintenance stand and the retainer lid that are fixedly connected.

Its technological points is:

Keep stand to comprise a plurality of support beams, offer groove in each support beam inboard, described a plurality of grooves form a circle groove at the internal diameter that keeps stand.

Keep stand to cover and be known technology, so repeated description not with retainer.The size of groove and the degree of depth are according to the width of retainer and thickness and decide.

Its advantage is:

This single row roller bearing keeps the stand inside diameter surface that one circle groove is arranged, and groove can play the lubrication of depositing dirt, oil storage, assurance bearing, has guaranteed that bearing rotates effect flexibly.And can save material, the retainer of single row roller bearing is generally the brass retainer of car system, and the reeded retainer of this internal diameter has been practiced thrift the raw material of copper greatly, has reduced cost of production.This bearing cage structure not only can reduce friction, can also oil storage play lubricated effect, can be widely used in NU, NJ, N, NUP, the isostructural single row roller bearing of NF.
