Abstract

The utility model relates to a rolling bearing, in particular to an internal lubricant injection type rolling bearing, comprising an outer ring (1) and an inner ring (3). A rolling body (2) is arranged between the outer ring (1) and the inner ring (3). Holders (4) are symmetrically arranged on the both sides of the rolling body (2). The bearing adopts an internal lubricant hole injection type structure which is provided with a lubricant hole (5) on the outer ring (1), and can also be provided with a lubricant hole (6) on the inner ring (3). The advantages of the internal lubricant injection type rolling bearing are that the maintenance is convenient, the internal lubricant injection type rolling bearing does not need to be dismounted when maintenance, the pressing fat or the dripping oil of the internal lubricant injection type rolling bearing is easy to control, the lubricant fat is accurately pressed or the oil is accurately dripped, etc.

Description

The internal lubricant injection type rolling bearing

Technical field:

The utility model relates to a kind of rolling bearing.

Background technique:

At present, rolling bearing engineering, weaving, chemical industry, etc. in the machinery utilization very extensive.And rolling bearing some phenomenons usually can occur in maintenance, using process, as: the rolling element that bearing lacks the improper damage of fat (oil) property, bearing cooperates pine spacious with the too early ultralimit of rolling element orbit gap, bearing damage in maintenance process, bearing with axle (or a bearing hole).The reason of these phenomenons mainly be rolling bearing in use: make when safeguarding in inconvenient, the non-demolition and maintenance process pressure injection lubricating grease (or the oil that instils) the wearer secondary enter in a large number roller track cause the wearing and tearing aggravation, when safeguarding in dismounting or running in bearings process unexpected the damage, frequent dismounting causes bearing to cooperate Song Kuanger to cause with spool (bearing hole).

Summary is got up, and the shortcoming of grease lubrication rolling bearing mainly contains following 2 points at present:

1. the lubricated axis of rolling of the fat of demolition and maintenance (oil) can't replenish when lacking lubricating grease (oil) immediately, inconvenience when safeguarding, and repeatedly demolition and maintenance make bearing cooperate pine spacious with bearing hole, seriously cause mechanical body to be scrapped.

2. its pressure injection lubricating grease (oil) amount of the non-demolition and maintenance rolling bearing of the outer pressure injection lubricating grease (oil) of employing bearing is uncontrollable, and, lubricating grease cause bearing operation overheated because of filling up bearing space, bring wearer into bearing inside in a large number simultaneously, make the bearing wear aggravation; Pressure injection lubricating grease (oil) in-position is inaccurate, and because of lubricating grease (oil) very few (or nothing) makes damage of bearings, the lubricating grease amount is too much squeezed bad other caulking gum parts (as engine cooling water pump) when serious.

Summary of the invention:

The purpose of this utility model is exactly in order to address the above problem, a kind of internal lubricant injection type rolling bearing is provided, it have easy to maintenance, need not dismantle, press fat (or instil oil) amount to control and make advantages such as lubricating grease pressure injection (or the oil that instils) accurately puts in place easily when safeguarding.

The utility model solution is as follows:

A kind of internal lubricant injection type rolling bearing, it is made of outer ring, rolling element, inner ring and retainer, described rolling element is arranged between outer ring and the inner ring, and described retainer then is symmetricly set on the both sides of rolling element, it is characterized in that described bearing adopts the injected inner hole moistening type structure.

Above-mentioned injected inner hole moistening type structure is for having the profit hole on the outer ring.

Above-mentioned injected inner hole moistening type structure is for having the profit hole on inner ring.

Lubricating grease (oil) just can directly enter the rolling element track by the profit hole on outer ring (inner ring) like this, and the auxiliary rotating that passes through bearing forms oil film attached to rolling element and rolling element raceway surface, need not dismantle when safeguarding, thereby reach purpose easy to maintenance, that save lubricating grease (oil) and lubricating grease (oil) pressure injection is accurately put in place.Make the wearer secondary enter the rolling element track in a large number when avoiding pressure injection lubricating grease (oil) simultaneously.

This kind internal lubricant injection type rolling bearing is compared with prior art:

Advantage be easy to maintenance, need not dismantle directly pressure injection when safeguarding, control, lubricating grease (oil) pressure injection accurately put, save lubricating grease (oil) 40%-60% in place to stuffing (oil) amount easily.

2. characteristics:

(1.) internal lubricant injection type, lubricating grease (oil) directly replenishes by bearing is inner through the profit hole.

(2.) high lubricating effect, lubricating grease (oil) directly arrives rolling element and rolling element raceway surface by the profit hole.

(3.) stuffing (oil) amount is stable, and pressure injection lubricating grease or instillation oil mass are controlled (1/2-1/3 of bearing space) easily.

Description of drawings:

Fig. 1 is an internal lubricant injection type cylinder roller bearing outer ring profit hole structure schematic representation;

Fig. 2 is an internal lubricant injection type cylinder roller bearing inner race profit hole structure schematic representation.

Embodiment:

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

With internal lubricant injection type cylinder roller bearing is example, it is by outer ring 1, rolling element 2, inner ring 3 and retainer 4 constitute, described rolling element 2 is arranged between outer ring 1 and the

inner ring

3,4 both sides that are symmetricly set on rolling element 2 of described retainer, have profit hole 5 (as shown in Figure 1) on the outer ring 1 or on inner ring 3, have profit hole 6 (as shown in Figure 2), its outer ring, rolling element, inner ring, the retainer actual size is identical with common rolling bearing, also promptly its agent structure of this kind internal lubricant injection type rolling bearing is identical with common rolling bearing, and its main difference point is to have profit hole 5 in outer ring 1 or have profit hole 6 on inner ring 3.Lubricating grease (oil) just can pass through the outer oil duct of bearing, directly enter bearing inside by the profit hole on the outer ring 1 like this, thereby realizes purpose of the present invention.The utility model manufacturing is simple, and Production of bearing producer can directly produce, in increasing () enclose outside the manufacturing procedure of profit hole, need not change other existing production process.The utility model working service is convenient.Be that machinery uses desirable rolling bearing.

Claims

1, a kind of internal lubricant injection type rolling bearing, it is made of outer ring (1), rolling element (2), inner ring (3) and retainer (4), described rolling element (2) is arranged between outer ring (1) and the inner ring (3), described retainer (4) then is symmetricly set on the both sides of rolling element (2), it is characterized in that described bearing adopts the injected inner hole moistening type structure.
