Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides the structure of a kind of novel skid bearing and friction, lubrication mechanism, mainly contain skid bearing and skid bearing oil feeding mechanism composition, wherein said skid bearing is primarily of weak elastic rolling body, slide mass, inner ring and outer ring composition, cavity is formed between described outer ring and inner ring, slide mass and weak elastic rolling body are installed in described cavity, described slide mass and weak elastic rolling body interval are installed, and described skid bearing oil feeding mechanism provides lubricant oil for skid bearing.
Described skid bearing oil feeding mechanism adopts the self adaption circulation-supplied mode of skid bearing oil.
Described skid bearing oil feeding mechanism is measured the friction power loss of oil film thickness, skid bearing and the motion of skid bearing, by critical temperature during friction power loss inspection lubrication failure, circulation impact power and Part Surface Roughness.
The critical temperature that described film lubrication lost efficacy is the temperature spots that minimum oil film thickness and maximum oil film shearing stress are corresponding.
The supply of skid bearing oil crosses that I haven't seen you for ages affects the hydrodynamic lubrication performance of its slide mass, supply too much can produce more heat because of the stirring of its rolling element; Unclean lubricant oil can affect the lubrication effect of bearing and increase friction; Bad sealing makes bearing oil easily pollute, leaks and evaporate.
The self adaption circulation-supplied mode that the skid bearing oil feeding mechanism provided of the present invention adopts.Ensureing that slide mass has enough dynamic pressure oil film thickness and rolling element to stir fluid and produces on the less benchmark of heat, the liquid viscous friction power produced with bearing inner race motion is for power; And the attitudes vibration making full use of slide mass is to transmit liquid; Utilize the gravity of liquid and the attitudes vibration withdrawal liquid of slide mass, realize the self adaption circulation-supplied of lubricant oil.By setting up the lubrication and seal system of a set of lubricant oil energy self adaption circulation-supplied, skid bearing is made can substantially to keep liquid friction running state long-term effectively.
Utilize the peculiar cavity structure of bearing outer ring to complete storage, the cooling of lubricant oil, utilize the weight of pollutant and settle magnetic substance to realize lubricating oil filtration at cavity inner wall.Utilize non-contact spiral groove to run the design philosophy of gas seal, at inner ring end face design spiral chute, set up by inner ring motion the sealing problem that solves lubricant oil with the pressure air film of leakage liquid motion reverse motions and fluid cools problem.
The good lubrication of skid bearing can effectively reduce the friction of relative movement part, alleviate the huge circulation impact of heavy duty, by detecting the viscosity characteristics of oiling agent under heavily loaded circulation impact, the slide mass oil film thickness of skid bearing, by analyzing the influence factor and correlation thereof that obtain skid Bearing and lubrication oil, being impacted by high duty cycle and the slide mass lubrication behavior of skid bearing is detected.Prevent to lubricate because of loading cycle impact failure by this embodiment and find oiling agent, design of part characteristic parameter (size, shape, surface roughness) and the matching gap that can meet needed for skid bearing lubrication performance under high duty cycle impacts.
Weak elastic rolling body is adopted to coordinate between rolling element and slide mass, make the enormous impact power that the no smooth undertaking rolling element of high duty cycle impact lower slider physical efficiency unloads, by the optimum shape finding most suitable weak elastic rolling body, slide mass produces good lubrication, obtain the behavior of rolling element resiliently deformable in the circulation impact next cycle of motion, the change of slide mass athletic posture, the oil-film force Changing Pattern of slide mass, carry out circulation impact power, the oil-film force of rolling element and the oil-film force three of slide mass act under the dynamic analysis of skid bearing and dynamic design.Object finds high duty cycle to impact design of part feature when lower rolling element and slide mass are coordinated good needed for bearing and matching gap.
During skid bearing working, friction (liquid viscous friction) causes energy ezpenditure, and the heat of generation can reduce lubricant oil viscosity, reduces oil film support force, change design of part feature (size, shape) and matching gap.By the foundation of the generation to frictional heat, transmission and thermal equilibrium state relation, the critical temperature that slide mass film lubrication lost efficacy, limiting value (maximum displacement response of oil film ultimate bearing capacity, the excitation cycle) restriction to bearing parts structural characteristic parameter value of thermal effect and part cold and hot deformation effect lower bearing static and dynamic performance detects.Target is that prevention lubrication Yin Wendu impact was lost efficacy and obtained the structure characteristic and matching gap that when skid bearing normally works, part need meet.
Novel bearing provided by the invention is the degree of depth derivative of rolling bearing and hydrodynamic sliding bearing, particularly it is by weak elastic rolling body and the ingenious collocation of rigidity slide mass, make it not only have the advantage of rolling bearing and hydrodynamic sliding bearing but also overcome their shortcoming, thus be particularly suitable for high duty cycle impact workplace.Utilize the motion of slide mass to set up the self adaption circulation-supplied of oiling agent, utilize the outer ring of hollow to store lubricant oil, play heat radiation, precipitated impurities and meet lubrication.
