Description
Technical field
The present invention relates to a kind of band bearing class product when carrying out the load moment of friction square test of bearing band, it can simulate on aircraft
The bearing attachment of connect band bearing class product point, measures after applying different directions, different size of load to product bearing and produces
The moment of friction square mechanism for testing for the torque index that product bearing rotates.
Background technology
Bearing frictional torque test is discussed using bearing under conditions of slowly running, test bearing friction and dynamic characteristics,
Bearing friction and dynamic characteristic curves are obtained, by analyzing the defects of judging, disclosing bearing and shafting, example to characteristic
Such as raceway misalignment, bearing preload lotus deviation, lubricating status, retainer dragging and other fortune in raceway impression, pollution, assembling
Turn problem, be the indispensable measurement of modern bearing manufacturing and bearing user, testing instruments.Utilize precision bearing frictional force
Square tester is examined, test, screening bearing, be very important work for bearing manufacturing, bearing user and must not
The quality control method that can lack.Bearing frictional torque tester is mainly by load maintainer and equilibrant force measurement in the prior art
System；Static pressure air-bearing main shaft head；Computer；Test software；Workbench；Measured bearing；Control cabinet；The portions such as mute air pump
It is grouped into.Have by interior axle, shell, power transmission pin, cantilever beam, stress strain gauge, strain acquirement analytical instrument and motor
Composition.This device drives interior axle to rotate using motor, and the inner ring of measured bearing rotates therewith, due to measured bearing
The torque signals of the inside and outside circle of bearing, are converted into the force signal of power transmission pin, into one by the effect of moment of friction between inside and outside circle
Step is converted into the strain signal of cantilever beam, then is measured with stress strain gauge, and strain signal is converted into electric signal,
The electric signal of stress strain gauge is converted with strain acquirement analysis system, is nursed one's health, realizes the survey of moment of friction eventually
Examination.Self-lubricating knuckle bearing is using a kind of joint of the low friction coefficient materials such as polytetrafluoroethylene (PTFE) between inner ring and outer ring
Bearing.When no-load starting moment of friction refers to that bearing is not subject to load, the inside and outside circle of bearing is since inactive state opposite turn to
The frictional resistance moment overcome required for dynamic moment.Compactness, the pretension situation of the inside and outside circle sphere of its concentrated expression bearing
And the frictional behaviour of selflubricating liner, be self-lubricating knuckle bearing an important parameter.According to outer ring structure, from
Lubricating joint bearing is divided into separable double half outside ring type and integral outer ring's formula.Integral outer ring's formula bearing uses extrusion molding work
Skill assembles the inside and outside circle of bearing, and compact-sized, application is wide.Since the friction mechanism of self-lubricating material is more complicated, rub
The influence that performance is vulnerable to the factors such as environment temperature and air humidity is wiped, the discreteness of friction factor is bigger.No-load starting power
Square value is smaller in itself, it is difficult to accomplish to measure under absolute " no-load " state.Self-lubricating knuckle bearing no-load starting moment of friction is surveyed
Since numerical value is small during amount, disturbing factor is more, it is difficult to accurate measurement.Work as bearing generally than relatively thin in the outer ring of self-lubricating knuckle bearing
During Rig up error, bearing outer ring easily is deformed, significantly affect the size of no-load starting moment of friction.So this technology
The measurement of index is always the problem of world's bearing industry.Self-lubricating knuckle bearing no-load starting friction is measured in actual production
The common method of torque is mainly:Counterweight method and the measuring method based on torque sensor.Counterweight method tests no-load starting power
Square, during test, first manually rotates 2~3 circles by bearing inner race, then bearing is installed on to the horizontal core of measuring device
On axis, with mandrel fixing bearing inner ring, by it is flat it is soft with one end adhesion and be wrapped in the excircle of measured bearing, the other end is hung
Counterweight.Constantly add counterweight, until outer ring starts to rotate, (m is counterbalance mass to the gravity mg of added counterweight, and g adds for gravity at this time
Speed) torque that produces is no-load starting torque as bearing.Counterweight method test device very simple, but measurement accuracy is low.
Radial load mg is also applied with bearing at the same time when loading counterweight, changes " no-load " state of bearing.In addition, loading weight
Synchronous codes sequence, place when consistent level, the loading capacity of last time have a great impact to test result, can bring compared with
Big random error.Counterweight loading is that have level loading, and operating personnel are difficult the loading capacity of accurate definite final step.Measurement is closed
During the no-load starting torque of bearings, easily because changing " no-load " state of measured bearing or changing the pretension of the inside and outside circle of bearing
State, makes the no-load starting torque of bearing produce offset, and brings significant systematic error.In the common measuring method of enterprise
In, counterweight method test device is simple, but can introduce bearing load, counterweight to have grade load mode will also result in larger random
Error.It can avoid changing the idling of bearing using torque tester method, but the method for clamping of measured bearing is to measurement accuracy
Have a great influence.Staring torque startingtorque makes a bearing ring or packing ring lasso or packing ring relative to another fixation
Start to rotate required torque.Turning moment runningtorque is prevented another when a bearing ring or packing ring rotation
Torque needed for lasso or packing ring movement.Radial load radialload acts on the load of vertical bearing direction of axis line.Root
According to frictional property, bearing can be divided into two class of rolling bearing and sliding bearing.Rolling bearing is universal standard part, and friction coefficient is very
It is small, it is only the 1/10 of sliding bearing.Sliding bearing structure is simple, cheap, and rigidity is larger.According to the direction for bearing load,
Bearing is divided into radial bearing:Substantial radial load.Such as:Self-aligning ball bearing, self-aligning roller bearing, can only bear axial load
The deep groove ball bearing thrust bearing of lotus.Bearing frictional torque directly affects the performance of bearing, is that one of rolling bearing is important
Performance indicator；It directly influences the loss of energy, is also related to the accuracy of precision instrument action and information transmission.Friction
Torque crosses the rising that conference causes bearing temperature, and undue temperature, which rises, will make lubricant deterioration, abrasion aggravation, even result in
Rolling surface is burnt, bearing damage.The principal element that must take into consideration when moment of friction is design bearing, both at home and abroad rubs bearing
The research for wiping performance is attached great importance to.The problem of bearing frictional torque is one sufficiently complex, quantitative study and measurement bearing friction
Torque is always the frontline subject of world's bearing industry.Bearing frictional torque is that bearing hinders it to move in rotary course
Torque summation.It is required in a flash that locked rotor torque (staring torque) is that two lasso of bearing is relatively rotated since inactive state to
The frictional resistance overcome；Dynamic force moment is the required frictional resistance moment overcome when two sets of bearing relatively rotates.It can be carried in measurement
Maximum moment, average torque and torque difference are taken as evaluation bearing dynamic friction performance parameter.Bearing is in rotary course, steel
Ball pure rolling caused by rotation and revolution motion in interior outer raceway groove is rubbed.Bearing is in rotary course, steel ball and inner and outer ring raceway
Juxtaposition metamorphose and the sliding friction that produces.Its bigger torque of general bearing size is also bigger, but bearing arrangement and design parameter
Difference, the influence to its torque is also different, such as ditch curvature, radial internal clearance and retainer parameter.Machining accuracy factor:Bearing
The size of moment of friction, bearing are worked under the conditions of bearing load, so also requiring having load when measuring torque
In the case of carry out, its moment of friction value also differs when measurement payload when application, direction (axially or radially) are different.
Air drag need to be overcome during bearing rotary, and adds the power attenuation of stirring lubricant, so the more high then torque of bearing rotating speed
It is bigger.When high speed measures torque, when turning moment running torque are a bearing ring or packing ring rotation, resistance
The only torque needed for another lasso or packing ring movement.When instantaneous peak value will surmount or be measured system by the rotary inertia of rotating part
System is absorbed and cannot truly reflected, and can only measure average friction torque.And maximum friction torque can only in extremely low rotating speed and
Measured under conditions of measuring system rotary inertia very little.Measurement position refers to that measured bearing axis is to be located at upright position
Or water position.When general instrument both domestic and external applies radial load to bearing, its measured bearing is horizontal, and to axis
When holding application axial load, its measured bearing is in vertical position.The motion state of the measurement position difference part of bearing also has
Institute is different, its moment values is not only of different sizes but also there is the difference of essence.In short, bearing frictional torque is a random change
Amount, wherein metastable torque part, is design factor and measuring condition.So bearing frictional torque be various influences because
The overall target of element, from the point of view of the part of torque and the influence factor of torque, the moment of friction value of bearing be exactly one with
Machine variable.Moment properties during practical bearing work may not be obtained, can not meet the performance requirement of host, bearing
Measurement of friction torque instrument is in addition to meeting the requirement of measuring principle and technical indicator, it is also necessary to required according to the difference of bearing,
Using different measuring methods, so bearing friction force torque measuring instrument device species is various, only disclose report just has nearly hundred both at home and abroad
Kind instrument.Most of mechanical devices using bearing connection installation product, using process middle (center) bearing can not in different size, no
Rotated under equidirectional load, in use, the problem of producing local part breaking often, be mainly manifested in the axis of connecting portion
Hold and be not rotated further by after some limit load is reached, the range of movement of mechanical device is significantly reduced, bearing occur can not turn
Dynamic phenomenon, and then part stress concentration occur and cause to be broken.At this stage be used for measure bearing band loaded-up condition lower inner ring with
The moment of friction square mechanism for testing of peak torque when outer shroud relatively rotates, the motion problems during use need to provide axis
Hold the moment of friction square index born in use under different directions, different size of load.Reduce and rub to greatest extent
It is to limit not possess the problem that special band carries bearing test function to wipe power and increase 1 range of movement of measured bearing.
