Abstract
The utility model discloses an angle stroke electric actuator which comprises an outer cover 1, an invertible motor 2, a position feedback gear wheel component 3, a controller component 7, a worm wheel box 9, a base 10 and an output shaft 11, wherein a driving gear wheel 5 is connected to the invertible motor 2, and a driven gear wheel 6 is connected to a worm screw 4 of the worm wheel box 9; the driving gear wheel 5 and the driven gear wheel 6 are engaged with each other. The transmission between the invertible motor and the worm wheel box is completed by the rotation of the driving gear wheel and the driven gear wheel. The utility model overcomes the disadvantages of easy abrasion and easy aging of the original belt wheel. Compared with the prior art, the utility model has the advantages of abrasion resistance and long service life.
Description
One, technical field
The utility model relates to a kind of valve actuator, specifically relates to the angle stroke electric actuator of using on a kind of valve.
Two, background technique
The reversible electric machine of existing angle stroke electric actuator is finished by being connected belt pulley with the transmission between the Worm gear case.And belt pulley wearing and tearing easily under running up for a long time, particularly poor at this final controlling element working condition, ambient temperature is too high or situation such as too low under, belt is aging easily, causes belt phenomenon of rupture to occur, make this final controlling element can't proper functioning, shorten its working life.
Three, model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of angle stroke electric actuator of wear-resistant, long service life is provided.
The purpose of this utility model realizes by following technical solution: a kind of angle stroke electric actuator, comprise that outer cover, reversible electric machine, position return feedback gear assembly, controller assemblies, Worm gear case, base, output shaft, on reversible electric machine, connect driving gear, on the worm screw of Worm gear case, connect driven gear, and driving gear and driven gear are connected with a joggle.
After adopting the utility model structure, finish, overcome the defective easy to wear, that easily wear out of former belt pulley because the transmission between reversible electric machine and the Worm gear case is rotated by driving gear and driven gear.Therefore, the utility model compared with prior art has anti abrasive advantage, has prolonged the working life of final controlling element.
Four, description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model angle stroke electric actuator.
Fig. 2 is the right elevation of Fig. 1.
Fig. 3 is the plan view of Fig. 2.
Five, embodiment
With reference to Fig. 1, Fig. 2, Fig. 3 as can be known, the utility model angle stroke electric actuator, comprise that outer cover 1, reversible electric machine 2, position return feedback gear assembly 3, controller assemblies 7, Worm gear case 9, base 10, output shaft 11, on reversible electric machine 2, connect driving gear 5, on the worm screw 4 of Worm gear case 9, connect driven gear 6, and driving gear 5 is connected with a joggle with driven gear 6.Wherein the position return the feedback gear assembly 3 comprise potentiometer 13, reversible electric machine 2 is contained on the connecting plate for electric motor 8; This final controlling element also can be equipped with manual drives assembly 12 (as shown in Figure 3), does manually control when shutting down in order to reversible electric machine.
Working procedure of the present utility model is: when reversible electric machine starts, drive driving gear and rotate, and then drive the driven gear rotation and worm screw is rotated.Transmission by Worm gear case rotates output shaft then, to open or throttle down.During this time, the time of valve opening and closing and angular dimension are regulated as required by controller assemblies and position feedback gear assembly.
Claims (1)
1, a kind of angle stroke electric actuator, comprise that outer cover (1), reversible electric machine (2), position return feedback gear assembly (3), controller assemblies (7), Worm gear case (9), base (10), output shaft (11), it is characterized in that: go up connection driving gear (5) at reversible electric machine (2), worm screw (4) in Worm gear case (9) goes up and connects driven gear (6), and driving gear (5) is connected with a joggle with driven gear (6).
