Specific embodiment
Below by specific embodiment, and in conjunction with attached drawing, the technical solution of the utility model work is further specifically retouched
It states:
Embodiment: as shown in attached drawing 1-5, a kind of ring cam set metering pump transmission mechanism, including the transmitting of deceleration mechanism, power
Component, travel adjustment 5, regulation indicator 4, the deceleration mechanism, travel adjustment, adjust instruction at power transfer member
Device collects on transmission case 6, and the deceleration mechanism includes motor 1, electric machine support 2, guider screw 3, crawler shoe 7, worm screw 9 and snail
Wheel 10, the motor output end connecting worm, the worm and wheel engage transmitting, the power and fortune of two between centers of spatial intersecting
Dynamic, power transfer member includes worm gear shaft 11, eccentric wheel 12 and deep groove ball bearing, and deep groove ball bearing is installed on the outside of eccentric wheel,
Eccentric wheel is installed on worm gear shaft, and three forms radial gear, is provided with eccentric wheel driving groove, stroke on travel adjustment
Adjuster cooperation eccentric wheel rotation move reciprocatingly, travel adjustment include toroidal frame 13, adjusting screw rod 16, balancing pole 15,
Deep groove ball bearing 14 and circlip for shaft, balancing pole pass through the sliding slot of adjusting bracket tail portion, and adjusting screw rod screws in toroidal frame, axis
The interstitial hole of head insertion balancing pole, hinged together with washer and split pin, deep groove ball bearing is loaded at balancing pole both ends and axis is used
Circlip, adjusting screw rod is opposite with the internal screw thread of toroidal frame tail portion to screw, and balancing pole just screws and axial position with adjusting screw rod
It moves, balancing pole position limits the stroke length of travel adjustment, regulation indicator cooperation rotation adjusting screw rod.Regulation indicator packet
It includes sleeve 17, dial 18, adjusting handle 19, chain bridge 20, hexagonal and pulls 21 and interior hexagonal holding screw 22, have mark on sleeve
Ruler, chain bridge cooperates with adjusting screw rod realizes the chain synchronous of adjusting handle rotation adjusting, and sleeve is fixed on transmission case, is adjusted
Dial is fixed on handwheel, adjusting handle is connect with bush whorl, and hexagonal, which is pulled, is fixedly connected with chain bridge and adjusting handle, and hexagonal is pulled
It is fixed with adjusting handle by interior hexagonal holding screw.Transmission case one end is fixedly connected with crawler shoe, and crawler shoe is socketed travel adjustment one
End, crawler shoe support travel adjustment one end, and provide the axially directed of travel adjustment reciprocating motion.Transmission case one end is fixed with
Bracket 8.Guider screw is fixed on transmission case, is respectively arranged at travel adjustment two sides, provides travel adjustment reciprocating motion
It is axially directed.
When utility model works, the power of worm and wheel engagement transmitting two between centers of spatial intersecting and movement.Worm gear shaft
The eccentric wheel of upper worm gear two sides changes power and movement, together forms the retarded motion of worm gear pair；The rotation of eccentric wheel is transported
Turn changes the reciprocating motion of travel adjustment into, and adjusting screw rod drives the stroke length of balancing pole control travel adjustment.When inclined
It when heart wheel deep groove ball bearing meets with the deep groove ball bearing on travel adjustment balancing pole and pushes, at this point, pump is in sucking row
Journey state.When suction stroke terminates, and eccentric wheel pushes two shoulder position on travel adjustment, pump is in discharge stroke shape
State；When regulation indicator is set up at 0 relative length of stroke position, travel adjustment will not generate reciprocating motion, i.e., no row
Journey.
Travel adjustment is the core of pump, and adjusting screw rod drives balancing pole to move back and forth, to change dead point after pump stroke
Position, so that the preceding dead point for realizing toroidal frame front end (plunger) is constant.
Regulation indicator is manual operation and the tool for indicating relative length of stroke position, provides toroidal frame reciprocating motion
Support and guiding role.Adjusting screw rod can turn can move to axial again；Dial can be to the instruction of pump stroke length
And reading, while being the guide slide of support and the reciprocating motion of travel adjustment tail end again；Chain bridge and adjusting screw rod cooperate
Realize the chain synchronization that adjusting handle rotation is adjusted.As long as synchronous rotary dial and adjusting handle can change the row of plunger
Cheng Changdu can read relative length of stroke value on dial and scale.
When the stroke of regulation indicator is designated as 0, start motor, pumps as 0 stroke, be in idling conditions.Work as dial
It rotates clockwise, 20% on the alignment scale of 0 on scale, left hand controls dial, and the right hand rotates clockwise adjusting handle simultaneously
It keeps up with dial to lock again, at this point, pump is run at 20% relative travel.If it is required that pump is in 100% relative length of stroke
Locate work, dial can be controlled with left hand, the right hand unscrews handwheel unlock counterclockwise, then dial is adjusted to 0 thereon clockwise
On alignment scale 100% at, handwheel synchronous rotary clockwise is kept up with dial and locked by the right hand, at this point, pump be 100%
It is run at relative travel.It is run if necessary to be transferred to from 100% relative length of stroke at 50% relative travel, with left hand control
Scale making disk, after right hand unlock, by dial rotation counterclockwise synchronous with adjusting handle, until 0 alignment scale of dial
On 50% when, then adjusting handle rotation is kept up with dial and locked, at this point, the pump just operation at 50% relative travel.Such as
This analogizes.
Embodiment described above is a kind of preferable scheme of the utility model, is not made to the utility model any
Formal limitation, there are also other variations and modifications on the premise of not exceeding the technical scheme recorded in the claims.
