Abstract
The utility model relates to a bearing, belong to the transmission field, concretely relates to loose rib bearing. Include: bearing inner race, bearing inner race, loose rib, wherein: bearing inner race's axial both ends are provided with two counter bores respectively, the loose rib sets up in this counter bore, bearing inner race's both ends are provided with the tang circle respectively, the hole of flat ring washer respectively with the tang circle interference fit at bearing inner race both ends, be provided with the radial rolling element of a plurality of between bearing inner race and the bearing inner race. Therefore, the utility model has the advantages of as follows: 1. Reasonable in design, simple structure and practical completely, 2. The rolling element rolls the body for needle -like, can be able to bear or endure big loading and impact, and movement resistance is little, 3. Adopt supply formula grease lubrication, coefficient of friction is littleer, 4. But the both ends retaining ring is the fixing bearing position both, can prevent dust again.
Description
Technical field
The utility model relates to a kind of bearing, belongs to transmission device field, is specifically related to a kind of loose rib bearing.
Background technique
Bearing is a kind of important spare part in contemporary machinery.Its major function is supported mechanical solid of rotation, reduces the friction factor in its movement process, and ensures its rotating accuracy.
By the difference of motor element frictional property, bearing can be divided into rolling bearing and the large class of sliding bearing two.Wherein rolling bearing standardization, seriation, but its radial dimension, vibration & noise is comparatively large compared with sliding bearing, and price is also higher.
Rolling bearing is generally made up of outer ring, inner ring, rolling element and retainer four part.By the shape of rolling element, rolling bearing is divided into ball bearing and the large class of roller bearing two.
Loose rib bearing is usually used in rectilinear orbit, and flat ring washer can prevent dust from entering in bearing affect bearing use, thus can extend bearing working life.Generally being made up of outer ring, inner ring, radial rolling element and loose rib, is sliding friction between outer ring and loose rib.But existing loose rib bearing bears radial load only, rolling element is difficult to bear large loading and impact, and resistance to motion is large.
As can be seen here, above-mentioned existing loose rib roller bearing with in use in structure, obviously still has inconvenience and defect, and is urgently further improved.
Model utility content
The utility model mainly solves the above-mentioned technical problem existing for prior art, provides a kind of loose rib bearing.This loose rib bearing roller is needle-like roll body, can withstand large loading and impact, and resistance to motion is little, adopts the grease lubrication of supply formula simultaneously, significantly can reduce friction factor, can be used in automobile, cultivator, lathe iso-variable velocity device.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of loose rib bearing, comprising: bearing outer ring, bearing inner race, loose rib, wherein: the axial two ends of described bearing outer ring are respectively arranged with two counterbores, and described loose rib is arranged in this counterbore; The two ends of described bearing inner race are respectively arranged with seam circle, the endoporus of described flat ring washer respectively with the seam circle interference fit at bearing inner race two ends; Several radial rolling element are provided with between described bearing inner race and bearing outer ring.
Optimize, above-mentioned a kind of loose rib bearing, described radial rolling element is needle roller.
Optimize, above-mentioned a kind of loose rib bearing, the central shaft of described bearing inner race is upwards provided with through hole.
Optimize, above-mentioned a kind of loose rib bearing, described bearing inner race is run through at least one end of described bearing inner via hole.
Optimize, above-mentioned a kind of loose rib bearing, described bearing outer ring, bearing inner race, loose rib form a cavity, are filled with Lubricants in described cavity.
Therefore, the utility model tool has the following advantages: 1. reasonable in design, and structure is simply and completely practical; 2. rolling element is needle-like roll body, can withstand large loading and impact, and resistance to motion is little; 3. adopt the grease lubrication of supply formula, friction factor is less; 4. two ends back-up ring both can rigid bearing position, again can be dust-proof.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.In figure, bearing outer ring 1, bearing inner race 2, loose rib 3, radial rolling element 4, through hole 5.
Embodiment:
A kind of loose rib bearing, comprising: bearing outer ring 1, bearing inner race 2, loose rib 3, wherein: the axial two ends of bearing outer ring 1 are respectively arranged with two counterbores, and loose rib 3 is arranged in this counterbore; The two ends of bearing inner race 2 are respectively arranged with seam circle, the endoporus of loose rib respectively with the seam circle interference fit at bearing inner race 2 two ends; Bearing outer ring 1, bearing inner race 2, loose rib 3 form a cavity, are filled with Lubricants in cavity.Also be provided with several radial rolling element 4 in this cavity, this radial rolling element 4 is preferably needle roller.The central shaft of bearing inner race 2 is upwards provided with through hole 5, and at least one end through-shaft of bearing inner via hole 5 holds inner ring 2.
Adopt after said structure, the new two ends loose rib 3 of this practicality compresses (interference) respectively on inner ring 2 seam, and by two ends, outer ring 1 inner stopper restriction back-up ring axial motion, rolling element installation wherein, forms an entirety, can not be split; Rolling element is needle-like roll body, can withstand large loading and impact, and resistance to motion is little.In bearing, adopt the grease lubrication of supply formula, friction factor is less.Two ends back-up ring both can rigid bearing position, again can be dust-proof.The utility model is mainly used in automobile, cultivator, lathe iso-variable velocity device.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the terms such as bearing outer ring 1, bearing inner race 2, loose rib 3, radial rolling element 4, through hole 5 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
