Description
Technical field
The present invention relates to pneumatic bearing, especially a kind of pneumatic bearing protective gear.
Background technique
Pneumatic bearing (being called air-bearing again) refers to the sliding bearing of gas as oiling agent.Air ratio oil viscosity is little, high temperature resistant, pollution-free, thereby can be used in high speed machines, precision type instrument and the radioactivity device.Pneumatic bearing provides high radial and axial running accuracy.Owing to do not have Mechanical Contact between rotor rotated and the static supporting part, so wearing and tearing do not produce, thereby it is stable to guarantee that precision remains.But pneumatic bearing is not having under the situation of air feed; Rotor rotated directly contacts with static supporting part, if the mechanism that at this time is connected with pneumatic bearing produces motion, then directly pneumatic bearing is produced wearing and tearing; Especially under the carrying situation, pneumatic bearing possibly will soon be damaged.
On the other hand; Pneumatic bearing is used for torque testing system has very big advantage; Torque sensor is connected with measured piece through pneumatic bearing, and the air bearing rotor does not have physics with static supporting part and contacts when rotatablely moving, so guarantees that measurement value sensor is exactly the torque value of measured piece; Do not have the influence of zerofriction force square, so pneumatic bearing there is greatly advantage in the highi degree of accuracy torque measurement.
Torque testing system must be demarcated torque sensor, and the method that adopts usually is to install to demarcate bar realization static demarcating, produces torque value through hanging the counterweight mode, verifies the precision of torque sensor thus.The present invention has designed a kind of pneumatic bearing device that the demarcation bar can directly be installed.
Summary of the invention
For the unprotect measure that overcomes existing pneumatic bearing, the deficiency of damaging easily, the present invention provides a kind of protectiveness by force, effectively to avoid the pneumatic bearing protective gear that damages.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of pneumatic bearing protective gear; Two pneumatic bearing about comprising; Be rigidly connected through sheath in the middle of said two pneumatic bearing, be provided with the intercommunicating pore with the inlet hole connection of two pneumatic bearing in the middle of the said sheath, said two pneumatic bearing are provided with inlet hole; Said two pneumatic bearing, sheaths are installed on the axle; Setting pressure sensor in the said inlet hole, said pressure transducer be connected in order to the Electromgnetic seat clutch controller of when detect pressure, controlling Electromgnetic seat clutch closure, said Electromgnetic seat clutch controller is connected with said Electromgnetic seat clutch; Said Electromgnetic seat clutch is installed on the axle, and the Electromgnetic seat clutch is connected with pneumatic bearing.
Further; Said protective gear also comprises the demarcation bar; Said sheath is provided with installation through holes and centering through hole with the axle middle part, and all through the same mid point of said axle, said demarcation bar passes the installation through holes at said sheath and axle middle part for said centering through hole and installation through holes.
Further, said protective gear also comprises check lock lever, and said check lock lever passes the installation through holes at said sheath and axle middle part.
Beneficial effect of the present invention mainly shows: 1, protectiveness by force, is effectively avoided damaging; 2, can directly carry out on-line proving to sensor.

Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
With reference to Fig. 1～Fig. 3; A kind of pneumatic bearing protective gear, two pneumatic bearing about comprising are rigidly connected through sheath in the middle of said two pneumatic bearing; Be provided with intercommunicating pore in the middle of the said sheath with the inlet hole connection of two pneumatic bearing; Said two pneumatic bearing are provided with inlet hole, and said two pneumatic bearing, sheaths are installed on the axle 6, setting pressure sensor 3 in the said inlet hole; Said pressure transducer 3 be connected in order to the closed Electromgnetic seat clutch controller 2 of control Electromgnetic seat clutch when detecting pressure; Said Electromgnetic seat clutch controller 2 is connected with said Electromgnetic seat clutch 1, and said Electromgnetic seat clutch 1 is installed on the axle 6, and Electromgnetic seat clutch 1 is connected with pneumatic bearing.
Said protective gear also comprises demarcates bar 8, and said sheath is provided with installation through holes and centering through hole with the axle middle part, and all through the same mid point of said axle, said demarcation bar 8 passes the installation through holes at said sheath and axle middle part for said centering through hole and installation through holes.
Further, said protective gear also comprises check lock lever 10, and said check lock lever 10 passes the installation through holes at said sheath and axle middle part.
In the present embodiment, two common pneumatic bearing about pneumatic bearing mechanism 7 comprises, the working principle of the protection of pneumatic bearing is following: 5 is the inlet hole of pneumatic bearing among Fig. 1; If not ventilation; The checkout value of pressure transducer 3 is zero, and passes to Electromgnetic seat clutch controller 2 to this signal value, control Electromgnetic seat clutch 1; This device and miscellaneous equipment (drive unit, deceleration loading device etc.) are thrown off, thereby play a protective role; Otherwise the inlet hole 5 of pneumatic bearing has ventilation, and the checkout value of pressure transducer 3 is non-vanishing, and passes to Electromgnetic seat clutch controller 2 to this signal value, and control Electromgnetic seat clutch 1 on making this device and miscellaneous equipment being connected, begins proper functioning then.
State shown in Figure 2 is the demarcation state.Be used for static demarcating is carried out in torque, concrete calibration method adopts conventional counterweight to demarcate, i.e. the fixing arm of force is through hanging the counterweight generation standard moment values of different quality.As shown in Figure 2; Demarcation bar 8 among Fig. 2 inserts pneumatic bearing mechanism 7 at the moment timing signal, and passes the installation through holes at axle 6 middle parts, axle 6 need rotate in advance in the middle part of installation through holes and the pneumatic bearing installation through holes over against; Demarcate the bar centre bit and be equipped with a pair of middle through hole; 4 is the centering through hole among Fig. 2, after demarcating bar insertion pneumatic bearing and axle 6, demarcates the bar central aperture centering through hole fixing demarcation in 4 backs bar.Can hang counterweight in demarcation bar both sides then and realize the torque value demarcation.
State shown in Figure 3 is a locking state.When this device was not tested, as shown in Figure 3, check lock lever 10 played and prevents that dust from getting into the effect of pneumatic bearing among Fig. 3.When needs are tested, at first take out check lock lever 10, could normally use then.
