Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail, so that above-mentioned advantage of the present utility model is clearer and more definite.
Fig. 1 is the structural representation of the utility model straight line electric push rod deployed condition;
Fig. 2 is the structural representation of the utility model straight line electric push rod contraction state.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1, the utility model push rod comprises mounting bracket 1, motor outer tube 2, motor 3, screw rod link cover 4, motor adapter sleeve 5, plane bearing 6, screw rod pressing plate 7, first butterfly spring sheet 8, locating sleeve 9, screw rod 10, nut 11, interior hexagonal ball screw 12, the 3rd plane bearing 13, second largest butterfly spring sheet 14, locating sleeve chock plug 15, interior aluminum pipe 16, push rod joint 17, soket head cap screw 18, rubber ring 19, power line 20, gear box 21.
Wherein, the afterbody link mounting bracket 1 of described motor outer tube 2, the head link motor adapter sleeve 5 of mounting bracket, motor 3 links with gear box 21, the output flange of gear box and motor adapter sleeve 5 motor that is fixedly connected, the bottom of locating sleeve 9 links stationary positioned sleeve pipe 9 with motor adapter sleeve 5, the output shaft of gear box 21 links with screw rod 10, being fixed on bottom the screw rod of screw rod adapter sleeve 4, the screw rod adapter sleeve be placed with first plane bearing 6 and second plane bearing, 6 ＇ up and down, the effect that is provided with plane bearing is to reduce friction, reducing the push rod running is the resistance that is subjected to, and, also putting screw rod pressing plate 7 on first plane bearing 6, the effect of screw rod pressing plate 7 is that anti-throw-out lever stroke part is pulled out push rod integral body.
In addition, the top of locating sleeve 9 links with locating sleeve chock plug 15, the effect that locating sleeve chock plug 15 plays be fixing in aluminum pipe 16 and stop that screw mandrel shifts the effect that the top can move forward onto.
In addition, first butterfly shell fragment 8 is placed on above the screw rod pressing plate 7, it produces noise in the time of can preventing the too loosening running of screw rod pressing plate 7 and plane bearing A6, can also lower the speed that push rod stops when working at high speed, has improved the useful life of screw mandrel 10, nut 11, plane bearing A6 motor 3, gear box 21.
In addition, interior hexagonal ball screw 12 is linked at the top of screw mandrel, and second largest butterfly shell fragment 14 and the 3rd plane bearing 13 are arranged between interior hexagonal ball screw 12 and the screw mandrel 10, and its effect is to prevent that it is stuck present appearance that throw-out lever is shifted range onto.And second largest butterfly shell fragment 14 can lower recoil and lower speed, and prevents that screw mandrel from having the push rod output to break away from push rod and can't work.
In addition, the bottom of aluminum pipe 16 in the external screw thread of nut 11 is linked at, aluminum pipe 16 top links push rod joint (17) and external linkages in the internal thread link screw mandrel 11, push rod joint 17, interior aluminum pipe 16, nut 11 are whole and and external linkages of one group of independent telescope.
In addition, also be provided with rubber ring 19, it is placed on the effect of playing locating sleeve chock plug 15 the insides is to prevent dust, and water etc. enter push rod inside, power line 20 link motor 3 and external controllers.
The utility model straight line electric push rod is performed such work:
At first, open motor 3, motor 3 lowers rotating speed by epicyclic gearbox 21, gear box 21 is fixed on institute above the motor adapter sleeve 5, the output shaft link screw mandrel 10 of gear box 21 is synchronized with the movement with the output axle bed of gear box 21, because screw mandrel 10 is trapezoidal thread screw mandrels, so can promoting nut 11 rotations when motion, screw mandrel 10 slowly rises, circular motion is transformed into rectilinear motion, there is nut 11 to be installed in interior aluminum pipe 16 bottoms, so interior aluminum pipe rises, aluminum pipe 16 tops and interior aluminum pipe 16 were synchronized with the movement in push rod joint link 17 was linked at, and promoted exterior part simultaneously and did rectilinear motion.
When push rod runs to range, slow down running speed as the second largest butterfly shell fragment 14 of Fig. 1, noise-decreasing, the 3rd plane bearing 13 contacts with the top of nut 11 with nut and rotates synchronously, reduced the damage of nut 11, following a slice of first butterfly shell fragment 8 reduces the wearing and tearing between screw rod link cover 4 and the motor adapter sleeve 5 simultaneously lower a part of frictional force along with screw rod link cover 4 rotates always simultaneously.Disable motor is stop motion.
When the rotation direction that changes motor is that the direction of push rod operation is also along with change, when push rod when pulling back, screw rod pressing plate 7 blocks screw rod adapter sleeve 4 and prevents that screw mandrel is drawn out because screw rod adapter sleeve 4 and screw rod 10 are can not breaking away from of being threaded togather, because return to produce relative displacement between the screw rod pressing plate 7 screw rod adapter sleeves 4, so also have second plane bearing, 6 ＇ to reduce to rub to reduce noise between them between screw rod pressing plate 7 and the screw rod adapter sleeve 4.When pushrod movement during to contraction state nut 11 be pressed onto that big video disc A8 underspeeds, noise-decreasing.Deenergization quits work.
In addition, this practical drive unit is installed in motor sleeve pipe 2 the insides, and is fixing with motor adapter sleeve 5 and mounting bracket 1.Screw mandrel 10, interior aluminum pipe 16, the locating sleeve 9 that only need change top when needs change the stroke of push rod get final product.Do not need to change all parts.
In addition,, and do not have bearing above the screw mandrel, make that the self-lock force between screw mandrel and the nut is very strong because screw mandrel uses is that the angle of elevation of trapezoidal thread structure screw mandrel is very low.
The beneficial effects of the utility model: this electric linear push rod, the making of comparing with former push rod is simple, rational in infrastructure, volume is little, and outward appearance is more exquisite, and noise is low, thrust is big, and this practical thrust that can promote is the 2-3 times of present push rod of the same type to 1800N in size of the same type.
Use big butterfly shell fragment and rubber blanket noise can reduce by 6 decibels, now obviously can be reduced to the 10-15 decibel in addition at high frequency motion.This is a very big improvement for electric pushrod.
This is practical has also removed push rod and has shifted manifesting that top or bottom can be stuck onto.Make push rod make it along with screw motion running to the bottom and can be expressed to plane bearing during the top because installed plane bearing additional.
Above-mentioned specific embodiment only is exemplary, and under above-mentioned instruction of the present utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improvement or distortion drop in the protection range of the present utility model.It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of this utility model, are not to be used to limit the utility model.Protection range of the present utility model is limited by claim and equivalent thereof.
