Abstract
The utility model discloses a linear driver with an improved transmission structure, which comprises a gearbox housing, a motor, a dustproof outer pipe, a worm gear and a worm; a gear set is arranged in the gearbox housing, and a master gear of the gear set is screwed with the horizontally-arranged worm; the worm is sleeved with the worm gear matched with the worm; an iron pipe is arranged on the outer side of the worm gear; and the dustproof outer pipe is arranged at the outer part of the iron pipe. The linear driver has the characteristics of simple structure, reasonable design, low cost, high efficiency, energy conservation and the like, and has huge market potential.
Description
Technical field
The utility model relates to the Drive technology field, especially a kind of Linear actuator with modified model drive mechanism.
Background technique
Linear actuator is widely used in various apparatuses.
Traditional Linear actuator adopts the full depth tooth roller box to carry out transmission, and not only velocity ratio is little, and load capacity is poor, and efficient is low, and cost height, power consumption and Security are low, can not satisfy existing society to product quality and staff's safe requirement.
Therefore, existing technology awaits improving.
Summary of the invention
For solving above-mentioned the problems referred to above of the prior art, the purpose of the utility model provides that a kind of velocity ratio is big, cost is low, efficient is high, energy-conservation, safe, stable drive and noiseless Linear actuator with modified model drive mechanism.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of Linear actuator with modified model drive mechanism; Comprise gear box casing, motor, dustproof outer tube, worm gear and worm screw; Be provided with gear train in the described gear box casing, the master gear of the gear train horizontally disposed worm screw that spins, this worm screw is provided with and is with the turbine that matches with worm screw; The said turbine outside is provided with iron pipe, and the outside of said iron pipe is provided with dustproof outer tube.
Compared with prior art; The beneficial effect of the utility model is: owing to adopt said structure, under the constant situation of worm gear, worm screw centre distance, only need to change velocity ratio that number of threads can make product and become big or diminish; Also at double increase or minimizing thereupon of gear-box load capacity simultaneously; Simultaneously the gear-box load capacity also thereupon at double increase or reduce, rising or falling speed is slack-off simultaneously or accelerate, not only cost is low, efficient is high; And energy-saving effect is remarkable, can satisfy the requirement of client's different loads; Because the drive mechanism self structure avoids product in use owing to the load that receives overburdening suddenly makes the accident that causes, improve product Security in use.The utility model is simple in structure, reasonable in design, has characteristics such as cost is low, efficient is high, energy-conservation, has huge market potential.
Description of drawings
Fig. 1 is the structural representation that the utlity model has the Linear actuator of modified model drive mechanism.
Each label is respectively among the figure: (1) gear box casing, (2) motor, (3) outer tube that prevents dust, (4) worm gear, (5) worm screw, (6) iron pipe.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to specify:
Referring to Fig. 1; A kind of Linear actuator with modified model drive mechanism of the utility model comprises gear box casing 1, motor 2, dustproof outer tube 3, worm gear 4 and worm screw 5, is provided with gear train in the described gear box casing 1; The master gear of the gear train horizontally disposed worm screw 5 that spins; This worm screw 5 is provided with and is with the turbine 4 that matches with worm screw 5, and said turbine 4 outsides are provided with iron pipe 6, and the outside of said iron pipe 6 is provided with dustproof outer tube 3.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified to the equivalent embodiment of equivalent variations; But all the utility model technological scheme contents that do not break away from, all still belong in the scope of the utility model technological scheme any simple modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
