Description
Technical field
This utility model relates to mechanical erection, electric automatic equipment technical field, is specifically related to a kind of bearing life testing machine.
Background technology
What China currently used the employing of high-speed precise machine tool main shaft bearing is all imported bearing, and domestic bearing can not meet the requirement of high-speed precise machine tool main shaft bearing mostly.My company researchs and develops precision machine tool base bearing now, substitutes imported bearing.Bearing to carry out bearing life test to new product High Speed Precision Angular Contact Ball Bearing before coming into operation, and my company there are currently no such high speed life test machine, domestic can't buy this equipment, so researching and developing the testing machine in high-speed precision bearing life-span voluntarily.
Summary of the invention
The purpose of this utility model is that providing one can simulate bearing uses environmental requirement, it is determined that whether new product bearing life meets design requirement, makes the high-revolving precision machine tool main shaft bearing of high accuracy realize the HZ250 high-speed precision bearing life test machine of production domesticization.
nullThe purpose of this utility model is achieved in that it includes experimental machine、Base 1、Axially loaded mechanism 2、Upper cover 5、Radial loaded mechanism 6、Shaft coupling 10 and electro spindle 11，Base 1 is arranged on bottom experimental machine，Upper cover 5 is arranged on experimental machine top，The frock of test bearing 8 is arranged on the intracavity of experimental machine，Frock includes that two are accompanied examination bearing 3、Two test bearings 7、Power transmission shaft 9 and axial lubricating structure 4，Axially lubricating structure 4 is arranged on test bearing 7 side，Axially loaded mechanism 2 is arranged on the frock side of test bearing 8，Radial loaded mechanism 6 is arranged on above the frock of test bearing 8，Shaft coupling 10 is connected with power transmission shaft 9，Power transmission shaft two ends connect two respectively and accompany examination bearing，Accompany for two and connect two test bearings in the middle of examination bearing，Power transmission shaft motoring ring test bearing inner race rotates，Electro spindle 11 connects electric control console.
This utility model the most so some technical characteristics:
1, described test bearing internal diameter is φ 100 ~ φ 200mm, and external diameter is φ 150 ~ φ 250mm.
The HZ250 high-speed precision bearing life test machine that this utility model R & D design manufactures, the new product high-revolving precision machine tool bearing for spindle of high accuracy is carried out life test, simulation bearing uses environmental requirement, judge whether new product bearing life meets design requirement, make the high-revolving precision machine tool main shaft bearing of high accuracy realize production domesticization.
This utility model by test bearing scope be internal diameter φ 100 ~ φ 200mm. external diameter be φ this machine of 150 ~ φ 250mm. can realize test axle 26000r/min stepless speed regulation, there is heating system, lubricating oil can be heated, the temperature of lubricating oil during the actual application of simulation bearing.The signals such as load, temperature, power consumption, pressure are gathered automatically, realizes monitoring and the function of display, there is the automatic alarm that breaks down, stopping function.This utility model performance is complete, practical, and equipment performance is stable, reaches the target of design, and be in a leading position in industry level.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings:
nullIn conjunction with Fig. 1，The present embodiment includes experimental machine、Base 1、Axially loaded mechanism 2、Upper cover 5、Radial loaded mechanism 6、Shaft coupling 10 and electro spindle 11，Base 1 is arranged on bottom experimental machine，Upper cover 5 is arranged on experimental machine top，The frock 7 of test bearing is arranged on the intracavity of experimental machine，Frock includes that two are accompanied examination bearing 3、Two test bearings 8、Power transmission shaft 9 and axial lubricating structure 4，Axially lubricating structure 4 is arranged on test bearing 8 side，Axially loaded mechanism 2 is arranged on the frock side of test bearing，Radial loaded mechanism 6 is arranged on above the frock of test bearing，Shaft coupling 10 is connected with power transmission shaft 9，Power transmission shaft two ends connect two respectively and accompany examination bearing，Accompany for two and connect two test bearings in the middle of examination bearing，Power transmission shaft motoring ring test bearing inner race rotates，Electro spindle 11 connects electric control console.
Upper cover 5 it is first turned on during test, the frock of test bearing is loaded the intracavity of experimental machine, frock mainly includes that two are accompanied examination bearing 3, two test bearings 8, power transmission shaft 9, axial lubricating structures 4, during work, according to new product bearing test requirement, determine the rotating speed of test bearing, and the size of axially and radially loading force, by electric control console, set the working speed of electro spindle 11 and axial, the setting of radial loaded power.Frock has connected, after axially loaded mechanism 2 and radial loaded mechanism 6 have loaded, control station starts electro spindle, and mechanism's power is driven by electro spindle, is connected with power transmission shaft by shaft coupling 10, power transmission shaft two ends be two accompany examination bearing in the middle of be two test bearings, transmission shaft driven, drives bearing inner race to rotate, it is achieved the mensuration to the test bearing life-span, lubricating structure is tested bearing lubrication simultaneously, it is ensured that bearing life test is smoothed out.Bearing control testing stand can show in real time test bearing axial-radial load size, by temperature sensor, the display signal such as bearing temperature and tank pressure automatically gathers, monitors and show function.
