Description

Large-scale automobile-used self-aligning roller bearing

Technical field

The utility model relates to field of bearings, and in particular to a kind of self-aligning roller bearing that large size is automobile-used.

Background technique

In recent years, with the fast development of building trade, oversize vehicle using more and more extensive, since bearing uses work The particularity of condition, the frequent continuous work of bearing, load is very big, and with shock loading, the aligning roller axis of ordinary construction The technical requirements for being unable to satisfy high-mechanic, large aligning angle degree at all are held, the service life and reliability for directly resulting in bearing are very It is low, and the self-aligning roller bearing of oversize vehicle is also subjected to very big axial load while bearing radial load, Bearing two-way bearing moment makes Bearing inner grease accelerate consumption, and lubricate to the service life of bearing and friction, abrasion, Vibration etc. has a major impact, and good lubrication is the necessary condition for guaranteeing bearing and running well, according to statistics, 40% or so bearing Damage it is all related with insufficient lubrication, when grease consume it is excessive and cannot timely repairing when, the working efficiency and service life of bearing It can greatly reduce.

Utility model content

The utility model provides a kind of self-aligning roller bearing that large size is automobile-used, consumes in the running to solve prior art bearing Oil mass, which rises, to make bearing frictional torque improve by fuel feeding in time, cause what bearing working efficiency and service life reduced to ask Topic.

A kind of self-aligning roller bearing that large size is automobile-used, including outer ring, inner ring and roller, the outer ring split settings are at master Body and annular clamping portion, the roller are rotatably arranged between main body and inner ring, and the annular clamping portion is equipped with flange rib, The mounting hole being fixed on for installing bolt for bearing on base, the annular clamping portion are evenly distributed on the flange rib It is mutually fixed with main body, the hollow setting in annular clamping portion is formed with grease storing chamber, and the main body is equipped with pump nozzle, the annular The oil outlet being connected to grease storing chamber is offered on clamping portion, the oil outlet is connected to form grease storing chamber and Bearing inner with pump nozzle Conducting, be provided with crushing block in the grease storing chamber, the depot fat cotton for storing grease, the storage be provided in the grease storing chamber Rouge cavity wall is equipped with the rubber ring being fixedly connected with crushing block, and the crushing block is made of shape memory alloy material, described There is the first form in crushing block, the crushing block has the second form, the crushing block at the second temperature at the first temperature Under the first form between depot fat cotton there are gap, the crushing block squeezes to form grease storing chamber under the second form to depot fat cotton To the fuel-displaced of pump nozzle, it is described annular clamping portion on offer several for toward grease storing chamber oiling repairing hole.

By adopting the above technical scheme it is beneficial that: outer ring split settings are at main body and annular clamping portion, so that annular clamping Portion can disassemble, and carry out replacing the components inside annular clamping portion convenient for operator, so that bearing reaches repetition and makes Function improves bearing service life, and annular clamping portion is fixed by flange rib with base, and crushing block passes through rubber ring It is fixed in grease storing chamber, and crushing block is made of that have shape memory alloy material, at work due to hub bearing, is rubbed Wiping acts on its temperature and will increase, and there is the first form at the first temperature at it, there are the second form, shape notes under second temperature Ultimum Ti, nickel titanium copper memory alloy, Fe-based shape memory alloy, copper-based memory alloy or tool can be used by recalling alloy material There are the other materials etc. of memory function, the martensite reverse transformation of memorial alloy completes the design value of temperature Af generally at 40-50 DEG C Between, so second temperature is the normal working temperature of hub bearing, the first temperature is then that is, at 40 DEG C, to squeeze lower than 40 DEG C Briquetting constancy of volume and there are gaps between depot fat cotton, when bearing is in off working state, crushing block will not be with depot fat cotton Contact causes grease to leak, and when hub bearing operating, especially the automobile hub bearing of oversize vehicle, temperature can reach 60-110, so that crushing block is heated, volume becomes the second form from the first form, and crushing block volume, which becomes larger, squeezes depot fat cotton, depot fat Cotton is squeezed fuel-displaced, is injected into Bearing inner by pump nozzle from oil outlet is fuel-displaced, lubrication Bearing inner is to improve bearing Working efficiency and service life, avoid oversize vehicle hub bearing because the excessively high acceleration for leading to lubricant grease of being heated is lost, together When due to rubber ring have elastic characteristic can be stretched with the increase of crushing block volume, will not influence its normal work, and The setting in repairing hole, when so that grease storing chamber internal grease disappearing, operator can increase by repairing hole to oiling inside grease storing chamber Add the service life of bearing.

The utility model is further arranged: several expression lobes are evenly equipped on the crushing block.

By adopting the above technical scheme it is beneficial that: expression lobes are evenly arranged on crushing block, when crushing block occur the second form When transformation, volume becomes larger, and expression lobes is driven to squeeze depot fat cotton, and adjacent expression lobes are combined to be formed and be squeezed to periphery depot fat cotton Pressure so that at the second temperature, depot fat cotton can sufficiently be extruded it is fuel-displaced, to lubricate bearing.

The utility model is further arranged: the pump nozzle is circumferentially arranged along main body end face, between the adjacent oil outlet Spacing etc..

By adopting the above technical scheme it is beneficial that: pump nozzle is circumferentially arranged along main body end face, and between adjacent oil outlet Spacing etc., when so that annular clamping portion being connected in main body, oil outlet can always be connected to oiling with pump nozzle, avoid It when annular clamping portion and main body are clamped, needs to repeat the position to its oil outlet and pump nozzle, improves operator's replacement zero Component rate.

The utility model is further arranged: it is provided with capping compatible with repairing hole on the annular clamping portion, it is described Capping combines the closing to be formed to grease storing chamber with repairing hole.

By adopting the above technical scheme it is beneficial that: capping with repairing hole combines the closing to be formed to grease storing chamber, so that repairing Hole can effectively prevent the grease of grease storing chamber from leaking when not needing oiling.

The utility model is further arranged: annular fixture block is provided on the annular clamping portion lateral wall, outside the main body Corresponding annular fixture block is provided with annular slot on side wall, and the annular fixture block and annular slot are engaged by clamping to form annular clamping portion With being fixedly connected for main body.

By adopting the above technical scheme it is beneficial that: annular fixture block and annular slot are engaged by clamping to form annular clamping portion and master Body is fixedly connected, while annular clamping portion passes through flange rib.
