Description
Technical field:
This utility model belongs to peristaltic pump field, particularly relates to a kind of worm and gear double reduction miniature peristaltic pump.
Background technology:
Peristaltic pump, it it is a kind of novel industrial pump, it is the product of development of modern industry, be widely used in the industries such as pharmacy, food, chemical industry, carry some with sensitivity, thickness, severe corrosive, there is ablation, purity requirement is high and medium containing certain granules shape material.
Existing peristaltic pump volume is relatively big, and structure is complicated.The worm and gear single-stage speed reducing that additionally peristaltic pump is commonly used at present, needs to take the biggest horizontal space to reach certain speed reducing ratio, thus causes whole peristaltic pump volume big, be not beneficial in narrow and small occasion or equipment application.
Utility model content:
This utility model overcomes the deficiency that prior art exists, and solves existing peristaltic pump volume bigger.Baroque problem, it is desirable to provide a kind of worm and gear double reduction miniature peristaltic pump, this peristaltic pump structure is the compactest, and reducing gear is novel in design, by increasing capacitance it is possible to increase the application scenario of peristaltic pump so that it is be applicable in little equipment.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: worm and gear double reduction miniature peristaltic pump, including motor, the output shaft of motor connects to be had worm screw and drives it to rotate, the side of worm screw is engaged with duplicate gear, duplicate gear side is engaged with output gear, and the top flank of tooth of output gear is provided with multiple Rotational Cylindrical, and Rotational Cylindrical completes to aspirate medium action with repeatedly extruding the peristaltic tube being arranged on Rotational Cylindrical side in output gear rotation process.
Further, the quantity of described Rotational Cylindrical is three, or is four, or is five.
Further, described Rotational Cylindrical is evenly distributed on the top flank of tooth of output gear.
Further, the top of described Rotational Cylindrical is installed with gripper shoe, and gripper shoe is all connected with the top of multiple Rotational Cylindrical.
Further, described Rotational Cylindrical includes the rotary column body of setting one-body molded with output gear, and the inside of rotary column body is fitted with metallic pin, and the outer sheath of rotary column body is equipped with pressure roller.
Further, described worm screw, duplicate gear and output gear are installed in gear-box, gear-box is made up of gear-box bottom and gear-box top cover, and gear-box top cover is provided above upper cover, and upper cover and gear-box top cover are fastenedly connected on gear-box bottom by fastening screw.
This utility model compared with prior art has the advantages that peristaltic pump of the present utility model slows down by being further added by one-level duplicate gear on the basis of worm and gear, add speed reducing ratio, the micromachine making little moment of torsion also can drive reducing gear, also reduces big retarding to be reached than necessary horizontal space simultaneously.Whole peristaltic pump structure is compact, rationally distributed, and volume is little, and moment of torsion is big, reduces the performance requirement to motor, and assembling is simple, and dependable performance is non-maintaining.
Accompanying drawing illustrates:
The utility model is described in more detail below in conjunction with the accompanying drawings.
Fig. 1 is detonation configuration schematic diagram of the present utility model.
Fig. 2 is the structural representation of Rotational Cylindrical.
In figure: 1 is motor, 2 is worm screw, and 3 is duplicate gear, and 31 is worm gear, and 32 is travelling gear, and 4 is output gear, 5 is Rotational Cylindrical, and 51 is metallic pin, and 52 is pressure roller, and 53 is rotary column body, and 6 is gripper shoe, 7 is gear-box bottom, and 8 is gear-box top cover, and 9 is upper cover, and 10 is fastening screw, and 11 is pump line.
Detailed description of the invention:
As shown in Figure 1 and Figure 2, worm and gear double reduction miniature peristaltic pump, including motor 1, the output shaft of motor 1 connects to be had worm screw 2 and drives it to rotate, the side of worm screw 2 is engaged with duplicate gear 3, duplicate gear 3 includes by worm gear 31 and travelling gear 32 is one-body molded forms, worm gear 31 engages with worm screw 2, travelling gear 32 engages with output gear 4, duplicate gear 3 plays gearing between worm screw 2 and output gear 4, and duplicate gear 3 can increase the speed reducing ratio of reducing gear on the basis of being not take up peristaltic pump horizontal space.
Duplicate gear 3 side is engaged with output gear 4, and the top flank of tooth of output gear 4 is provided with multiple Rotational Cylindrical 5, and uniform in order to make wriggling pump out liquid, described Rotational Cylindrical 5 is evenly distributed on the top flank of tooth of output gear 4.Rotational Cylindrical 5 completes to aspirate medium action with repeatedly extruding the peristaltic tube being arranged on Rotational Cylindrical 5 side in output gear 4 rotation process.
During work, starting motor 1, the output shaft of motor 1 drives worm screw 2 to rotate, and worm screw 2 transmission worm gear 31, worm gear 31 band nutating gear 32 rotates, thus drives output gear 4 to rotate.What three Rotational Cylindrical 5 that output gear 4 drive during rotating moved in circles rolls pump line 11, thus reaches to aspirate the purpose of medium.
As in figure 2 it is shown, the structure of Rotational Cylindrical 5 is: include the rotary column body 53 of setting one-body molded with output gear 4, the inside of rotary column body 53 is fitted with metallic pin 51, and the outer sheath of rotary column body 53 is equipped with pressure roller 52.Internal employing metallic pin 51 increases Rotational Cylindrical 5 structural strength, and outside pressure roller 52 uses other materials, is possible to prevent Rotational Cylindrical 5 to damage pump line 11.
In order to increase the structural strength of Rotational Cylindrical 5 further so that it is stability of rotation, being installed with gripper shoe 6 at the top of Rotational Cylindrical 5, gripper shoe 6 is all connected with the top of multiple Rotational Cylindrical 5.Multiple Rotational Cylindrical 5 are connected as an entirety by gripper shoe 6, it is possible to realize rotation-limited post 5 and the purpose of bracing reinforcement Rotational Cylindrical 5.
Not limiting the quantity of Rotational Cylindrical 5 above, the quantity of Rotational Cylindrical 5 is three, or is four, or is five.The quantity of Rotational Cylindrical 5 can increase and decrease according to the actual demand of flow or pulsation.
Additionally, in order to increase the sealing property of whole peristaltic pump, worm screw 2, duplicate gear 3 and output gear 4 are installed in gear-box, gear-box is made up of gear-box bottom 7 and gear-box top cover 8, gear-box top cover 8 is provided above upper cover 9, and upper cover 9 and gear-box top cover 8 are fastenedly connected on gear-box bottom 7 by fastening screw 10.Upper cover 9 is for spacing pump line 11 and fixing output shaft.Gear-box plays sealing, positioning action.
In sum, peristaltic pump structure of the present utility model is compact, rationally distributed, and volume is little, and moment of torsion is big, reduces the performance requirement to motor 11, and assembling is simple, and dependable performance is non-maintaining.
Above in conjunction with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art are possessed, it is also possible on the premise of without departing from this utility model objective, various changes can be made.
