Abstract
The utility model discloses a synchronous rotating piston and counterweight device of a piston pressure gauge, characterized in that a speed regulating motor drives a rotating sleeve to rotate via a belt, the rotating sleeve drives a synchronizing wheel to rotate synchronously, and the synchronizing wheel drives a piston and a counterweight placed on a bearing sleeve to rotate. By using the synchronous rotating piston and counterweight device of the piston pressure gauge, the disadvantage is overcome that when the piston and the counterweight in an original device are started, the rotation is not stable to cause that the piston is easy to damage; and by arranging gaskets between the upper and lower rings of the synchronizing wheel, pistons of different heights can use the same device.
Description
Technical field
The utility model relates to the pressure measurement technical field, specifically is synchronous rotating piston of piston manometer and counterweight device.
Background technology
Piston manometer is a kind of standard of pressure measurement, and the calibrating and the amount that are mainly used in pressure magnitude pass.In verification process, need piston and counterweight to rotate to overcome to cause influence to accuracy because of friction force.After piston rotation armrest or rotating mechanism drive, after making piston position climb away rotating mechanism, internal pressure rotates freely through increasing.
Usually the rotation of piston and counterweight has dual mode: rotate counterweight with hand and drive piston rotation perhaps by driven by motor; The employing constant speed motor starts; Drive a rotary body by motor through belt and rotate, promote one by the ratchet of installing on the rotary body again and rotate with the montant that counterweight mechanism is connected with piston.
The problem of current existence is: be with the hand propelled counterweight or promoting montant with ratchet all is that single-point or line promote piston and counterweight rotation; Rotation when piston and counterweight start is unstable; Swing when causing counterweight to begin to rotate; Can stablize after need rotating freely a period of time, can carry out measurement verification after stablizing; Drive the mode of piston and counterweight rotation with ratchet, when piston and counterweight fell, montant can drop on the ratchet and impact sometimes, causes bigger swing, even can cause the damage of piston.
Summary of the invention
The technical matters to be solved of the utility model is: solve rotation instability problem and montant when piston and counterweight start in synchronous rotating piston of present piston manometer and the counterweight device and drop on to impact on the ratchet and cause bigger swing, even can cause the damage problem of piston.
For achieving the above object, the utility model provides synchronous rotating piston of a kind of improved piston manometer and counterweight device to prior art, the rotation instability problem when using adjustable speed motor to reduce piston and counterweight startup on the one hand; Drive piston and counterweight smooth rotation through the friction force of using upper and lower two ends of synchronizing wheel " face " contact to produce on the other hand; The form that " increases " " subtracting " pad between synchronizing wheel is two-layer is adjusted; Make the synchronizing wheel height satisfy the height requirement of different pistons; Change stressed bearing into radial thrust bearing by radial bearing, increase " axle " ability to bearing load.
The technical scheme that the utility model adopts is: synchronous rotating piston of a kind of piston manometer and counterweight device; Comprise buncher, belt, turnbarrel, synchronizing wheel, piston, load-bearing sleeve, counterweight, radial thrust bearing; Buncher rotates through belt driven rotary sleeve; Turnbarrel drives synchronizing wheel and rotates synchronously, and synchronizing wheel drives piston and rotates through radial thrust bearing with the counterweight that is placed on the load-bearing sleeve; Between the ring pad is arranged on ring and the synchronizing wheel under the synchronizing wheel.
Beneficial effect: adjustable speed motor can make piston and counterweight after slow-speed of revolution slow-roll stabilization, progressively is transferred to high rotating speed again, the more stationarity that makes the rotation of piston and counterweight; Make synchronizing wheel convert the mode that " face " contacts with counterweight mechanism to from " point " way of contact, after piston and counterweight start, when rise is freely rotated, rotate more steady with piston; Piston and counterweight rise to rotate freely to be examined and determine, and what contact after calibrating is accomplished piston and counterweight is fallen is a face, rather than a point, can not cause the swing once more and the impact of piston and counterweight; Two-layer inside and outside synchronizing wheel is designed to, can adjust the height of synchronizing wheel between two-layer through the mode that increases pad quantity, the piston that is fit to differing heights is installed.So use this device to improve the security that piston uses, prolonged the serviceable life of instrument.
