Description

Spring steel skeleton double-row full-complement cylinder roller bearing
Technical field
The utility model relates to field of bearings, concretely, relates to the spring steel skeleton double-row full-complement cylinder roller bearing on a kind of pulley that is used for hoist industry large lifting equipment.
Background technique
Roller bearing is a kind of application bearing very widely, usually be divided into structures such as single-row, biserial and four row, wherein double-row full-complement cylinder roller bearing can also bear tilting moment except can bearing very big radial load and thrust load, therefore, be commonly used for rigid bearing.The double-row full-complement cylinder roller bearing of using on the pulley, contact seal is adopted at two ends, is filled with lubricating grease in the seal ring.Preferably under the situation, lubricating grease can prolong the operating life of bearing in service condition.Can carry out again lubricated by oil groove on the outer ring and oilhole.If same several Bearing Installation are on an axle, then because the outer ring is narrower than inner ring, so the rotating speed of outer ring can be different.These characteristics are fit to pulley mechanism, are fixed to easily on the bearing outer ring for making pulley, and the circular groove of shooting property back-up ring is all arranged at the bearing outer ring two ends.This kind bearing at present in the world each major company generally to adopt TPU(be polyamine ester, a kind of thermoplastic elastic body rubber) contact seal, outer astragal centre rib, external diameter two ends, outer ring are respectively with the circular groove of shooting a property back-up ring, interior coil structures is the independent inner ring of two two ribs of band, the middle part, footpath is connected and fixed by connecting folder within it, uniform 3 lubrication oil holes on the connection folder, and the oilhole that connects on the folder needs to aim at the oilhole of bearing inner race and fix.There is following drawback in this kind structure: seal ring is because exoskeletal support, and diameter and the width direction that must pay attention to during design at TPU leave enough spaces, otherwise very easily causes bearing TPU when lubricated once more to be extruded bearing, thereby causes bearing failure.Because seal ring takies than large space, cause the length of rolling element design to shorten to some extent simultaneously, under the prerequisite that guarantees same rolling element diameter, cause bearing load carrying capacity to descend to some extent.In addition, two inner rings need to press from both sides connection by connection, and the assembling of connection folder need be used mould, and mould is owing to size-constrained, and the manufacturing more complicated, and it is difficult to assemble the connection folder, can not guarantee assembly quality fully, occurs waste product easily, delivers goods thereby influence.In a word, conventional structure is more loaded down with trivial details from being designed into manufacturing, the manufacture cost height, and the friendship phase is longer.
Summary of the invention
Defective in view of the prior art existence, the purpose of this utility model provides and a kind ofly saves manufacture cost, shortens the manufacture cycle, reduces assembling difficulty, improves finished product trap rate, prolongs the bearing spring steel skeleton double-row full-complement cylinder roller bearing in working life, this bearing can also bear tilting moment except can bearing very big radial load and thrust load.
Spring steel skeleton double-row full-complement cylinder roller bearing, comprise outer ring, inner ring, rolling element, seal ring, it is characterized in that: the outer ring is three ribs, be processed with two seal ring filling notches at two outside ribs, there is the circular groove of two shooting property back-up rings the external diameter both sides, and an annular lubrication groove and uniform three lubrication holes are arranged at the middle part of external diameter; Inner ring has a rib, at the inner ring opposite side loose rib of an activity is arranged, and the inner ring and the loose rib outside respectively have the step of a big chamfering of R type, are used for cooperating with the sealing lip of seal ring; An annular lubrication groove and uniform three lubrication holes are arranged at the middle part of internal diameter; Two row have the rolling element that circular arc modified line bus is repaiied type, no retainer; The 65Mn material is housed in the bearing both sides does skeleton, NBR(nitrile butadiene rubber) seal ring.
Described rolling element one row is 31, and two rows amount to 62.
Described bearing ring is all handled through phosphatization, an amount of SHELL Alvania RL3 board lubricating grease of the inner filling of bearing.
The utility model has following advantage compared to existing technology:
1. all handle through phosphatization on the utility model bearing ring surface, look unfamiliar fine and close black phosphating film uniformly at ring table, film thickness monitoring makes the bearing itself under complex working condition have corrosion protection and lubrication at 0.005-0.008mm, has prolonged bearing working life.Sealing lip for seal ring and bearing inner race mating part, phosphating coat can prevent external foreign matter corrosion seal lip, avoid simultaneously sealing too early wearing and tearing, thereby cause bearing early failue, also have the function that impurity such as external dust of preventing and water are invaded bearing inside.
2. the utility model bearing seal ring framework adopts 65Mn, seal ring matrix adopting NBR(nitrile butadiene rubber).It is high that the relative 08Al of 65Mn material hardness wants, and elasticity and plasticity are good, and is in use not yielding, and uniform sealing load can be provided, and seal ring is difficult to come off from bearing.Compare 08Al, 65Mn skeleton fatigue resistance is high a lot, long service life.When guaranteeing good sealing effect, with low cost, buying easily.The temperature range that the NBR seal ring is suitable for is bigger, generally can adapt to the wide territory temperature range of 40 degrees below zero to 120 degree above freezing.This sealing ring material hardness is moderate, and oil resistant, abrasive resistance excellence have good mechanical property and tightness, effectively guarantee the sealing effect of bearing, prolongs bearing working life.
3. the utility model bearing adopts SHELL Alvania RL3 board lubricating grease, this lubricating grease is high-quality, the multipurpose industrial grease that is used under the moderate temperature conditions, form by high viscosity index (HVI) mineral oil and the blending of lithium soap base thickening agent, and contain wear-resistant, anticorrosive additive.Can in long-term using process, keep good performance.Contain suitable base oil viscosity and water-thickening agent in this lubricating grease, have favorable mechanical stability, can effectively reduce the friction between the bearing and reduce the degree of wear between the part.Long service life, the reliability height.
4. the seal groove of bearing outer ring both sides occupies little space, and compact structure is reasonable.Every side end face has a sealing filling slot apart from the outside appropriate location of rib diameter in the outer ring, and notch becomes 30 degree angles with cycle surface, so both helped the filling of seal ring, can prevent effectively that again seal ring from coming off from seal groove.Seal ring is installed for being more convenient for, one right angle is arranged at slotting position and cycle surface intersection.Have a circular groove at outer ring external diameter middle part, uniform three lubrication holes in circular groove help in use lubricated once more of bearing.
5. bearing inner race has a rib, the loose rib that an activity is arranged at the inner ring opposite side, She Ji benefit is to have saved the connection of two two rib inner rings in the conventional design like this, the Bearing Installation working service is become to be realized easily, and can save to make and produce the expense that connects clamp mould, can effectively shorten the manufacture cycle.Avoid conventional design to connect the folder oilhole and be difficult to align with inner ring end face lubrication hole and in use be connected folder oilhole and the easy phenomenon that breaks away from of inner ring lubrication aperture, thereby guaranteed the light realization that bearing is lubricated again.In addition, can also save a part of material.
