Abstract
The invention provides one kind to be based on pneumatically supported ultrahigh speed artificial rotary table device, belongs to artificial rotary table engineering device technique field.The present invention includes：Preposition air-bearing, rearmounted air-bearing, used axle, work top, motor and its drive device and base, the preposition air-bearing and rearmounted air-bearing are separately mounted on base, used axle is rotatablely connected with preposition air-bearing and rearmounted air-bearing respectively, motor and its drive device are fixed on base, the output end of motor and its drive device is connected with the rear end of used axle, and used axle is fixedly arranged at the front end with work top.The present invention is compared with prior art, overcome technology prejudice, combined using the air-bearing of preposition air-bearing and rearmounted air-bearing, the effect of big air-bearing is realized by less air-bearing, because small air-bearing can have very high maximum permissible revolution, and its bearing capacity can be improved by double air-bearings, this design can also improve the rigidity and resistance to capsizing of system.
Description
Technical field
The present invention relates to one kind to be based on pneumatically supported ultrahigh speed artificial rotary table device, belongs to artificial rotary table engineering device technique field.
Background technology
Shell has very high rotating speed after the transmission, needs one kind to have ultrahigh speed in the ground simulation to shell
The artificial rotary table of rotatory power, this for shell ground simulation highly significant.
Application publication number is CN102042834A, data of publication of application is on May 4th, 2011, entitled " single shaft ultrahigh speed turns
The application for a patent for invention of platform " discloses a kind of ultrahigh speed turntable of single shaft, it comprise at least have rotary test mechanism, monitoring box and
Chassis, by transforming original motor, improve motor reel and honour the endurance of axial load and to vibrations
Resistance, the rotating speed and precision of single-shaft superspeed rotary table are improved using Integral type rotary mechanism for testing.
Paper " structure design of a certain axle high speed turntable " (see《Electric mechanical engineering》The 5th phase 22- of volume 30 in 2014
Page 24) in describe a kind of Novel turntable structure, it without complexity driving-chain, using reducing motor direct driven antenna.With
Traditional turntable form is compared, and it has the advantages that simple in construction, transmission efficiency is high.Meanwhile the turntable is applicable to high rotating speed
Occasion, output speed is up to 60r/min.
Rotating speed can not improve much in the technical scheme that can be found at present, and rotating speed of target is designed as tens thousand of turns per minute.
For ultrahigh speed, subject matter is the selection of bearing, and bearing, which has selected big, can cause the maximum speed reduction that it allows, bearing choosing
That selects is too small, and its bearing capacity is unsatisfactory for requiring again.
The content of the invention
The invention aims to solve the above-mentioned problems of the prior art, and then provide a kind of based on pneumatically supported super
High-speed simulation rotation table device.
The purpose of the present invention is achieved through the following technical solutions：
One kind is based on pneumatically supported ultrahigh speed artificial rotary table device, including：Preposition air-bearing, rearmounted air-bearing, used axle,
Work top, motor and its drive device and base, the preposition air-bearing and rearmounted air-bearing are separately mounted to base
On, it to be used to axle and is rotatablely connected respectively with preposition air-bearing and rearmounted air-bearing, motor and its drive device are fixed on base,
The output end of motor and its drive device is connected with the rear end of used axle, and used axle is fixedly arranged at the front end with work top.
The present invention compared with prior art, overcomes technology prejudice, using preposition air-bearing and rearmounted air-bearing
Air-bearing combines, and the effect of big air-bearing is realized by less air-bearing, because small air-bearing can have very
High maximum permissible revolution, and its bearing capacity can be improved by double air-bearings, this design can also improve system
Rigidity and resistance to capsizing.

Bearing 1 and rearmounted air-bearing 2 are separately mounted on base 7, be used to axle 3 respectively with preposition air-bearing 1 and rearmounted air-bearing 2
Rotation connection, motor and its drive device 6 are fixed on base 7, after the output end of motor and its drive device 6 and used axle 3
End is connected, and used axle 3 is fixedly arranged at the front end with work top 4.
Protective cover 5 is also included based on pneumatically supported ultrahigh speed artificial rotary table device, the protective cover 5 is arranged on work top 4
On.Protective cover 5 is installed on work top 4, test load can be surrounded to prevent from flying out during high-speed simulation wherein and hurted sb.'s feelings.
The foregoing is only a preferred embodiment of the present invention, these embodiments are all based on the present invention
Different implementations under general idea, and protection scope of the present invention is not limited thereto, it is any to be familiar with the art
Technical staff the invention discloses technical scope in, the change or replacement that can readily occur in, should all cover the present invention's
Within protection domain.Therefore, protection scope of the present invention should be defined by the protection domain of claims.
